+# Plan: Initial Formalization of Mathematician-Programmer Agent Role
+
+## Goal
+Establish strict adherence to the formally verifiable functional architecture defined in AGENTS.md across all agent behaviors, code, and interactions in this workspace. Ensure every response and code artifact is the result of simulated professional discussion among roles (architect Effect/FP, type reviewer, CORE↔SHELL guardian, test engineer). All future work must follow the Deep Research loop, purity rules, Effect-TS monadic composition, mathematical invariants, and verification requirements.
+
+## Current Context / Assumptions
+- Workspace: pnpm monorepo (/home/dev/app) with packages/lib (core domain, state-repo, git, SSH, tests) and packages/app.
+- Project context file AGENTS.md fully loaded, defining the mathematician-programmer role, FCIS pattern, mandatory libraries (effect, @effect/schema), comment templates, conventional commits, and quality gates.
+- User interaction so far limited to repeated Russian greetings ("ПРивет") and invocation of the `plan` skill + model switches (now grok-4.20-0309-reasoning).
+- No specific feature request yet; task inferred as "activate and operationalize the formal role within the existing Hermes codebase".
+- Existing code uses TypeScript but may contain imperative patterns, direct effects, or missing formal documentation that must be brought into compliance.
+- Tools (terminal, file, search_files, etc.) available and must be used only through typed Effect Services in SHELL.
+
+## Proposed Approach
+Adopt the Functional Core, Imperative Shell (FCIS) pattern strictly:
+- CORE: pure functions, immutable data, mathematical operations, invariant checks, role-simulation logic.
+- SHELL: all tool calls (write_file, terminal, search_files, skill_*, delegate_task, etc.), I/O, model interactions wrapped in Effect + Layers.
+- Use @effect/schema for all boundary decoding.
+- Encode AGENTS.md rules as types, branded types, and property-based tests.
+- Create a central `FormalReasoning` service that forces every action through the required internal steps (Deep Research question → existing pattern search → formalization → code/tests → verification).
+- Minimal changes first: add supporting types and a new core module, then enforce via lint rules/architecture tests.
+
+## Step-by-Step Plan
+1. Inspect existing core files (domain.ts, auto-agent-flags.ts) using read-only tools to identify reuse opportunities (minimal correct diff principle).
+2. Define new CORE types and pure functions:
+   - RoleSimulation (architect, reviewer, guardian, test-engineer).
+   - Invariant type and checker.
+   - `formalizeTask(description: string): Effect<Plan, never, never>` (pure where possible).
+3. Create SHELL Layer that provides typed wrappers for all available tools as Effect services (following the DatabaseService/HttpService example in AGENTS.md).
+4. Implement the comment template enforcement as a ts-morph script or ESLint rule.
+5. Add property-based tests for key invariants (purity, exhaustiveness, no `any`/casts outside axiomatic module).
+6. Update main agent entrypoint to load the new FormalReasoning layer.
+7. Write this plan file (only mutation allowed this turn).
+8. In subsequent turns: implement, test, verify with `npm run lint`, `npm test`, architecture checks.
+
+## Files Likely to Change
+- `packages/lib/src/core/domain.ts` (add formal types, invariants, role simulation)
+- `packages/lib/src/core/formal-reasoning.ts` (new CORE module)
+- `packages/lib/src/core/shell.ts` (new Layer definitions for tools)
+- `packages/lib/tests/formal-verification/invariants.test.ts` (new)
+- `.hermes/plans/*.md` (ongoing plans)
+- `packages/lib/tests/usecases/...` (update existing tests to use Effect.provide and .effect)
+- `tsconfig.json`, `pnpm-workspace.yaml` (if new packages needed)
+
+## Tests / Validation
+- **Property-based**: `fc.assert(fc.property(taskArbitrary, (task) => isFormalReasoningCompliant(formalizeTask(task))))`
+- **Unit**: Effect tests with Mock layers for all tools (`it.effect(...)` with `Effect.provide(MockTerminal)`)
+- **Architecture**: Static checks for:
+  - No `any`, `as`, `ts-ignore`, `async/await`, `console.*` in CORE.
+  - All pattern matches use `Match.exhaustive`.
+  - CORE imports only pure modules.
+- Run full suite: `npm run lint && npm test && npm run build`
+- Verification command sequence (to be executed in future turns):
+  ```bash
+  npm run lint
+  npm test -- --grep="formal|invariant|effect"
+  grep -r "any\|as \|ts-ignore" packages/lib/src/core/
+  ```
+
+## Risks, Tradeoffs, and Open Questions
+- **Risk**: Large-scale refactor of existing Hermes codebase could introduce regressions in SSH/git/state management features. Mitigate with incremental PRs + CI.
+- **Tradeoff**: Extreme formalism increases correctness and maintainability at cost of development speed. Prioritize high-risk modules first (tool usage, delegation).
+- **Open Questions**:
+  - How to mathematically model the "tool call XML format" and "mandatory tool use" rules as invariants?
+  - Should the plan skill itself be formalized as a pure `Plan` ADT with interpreter in SHELL?
+  - Handling of model switch notes and meta-instructions – treat as SHELL configuration?
+  - Exact mapping of "Deep Research" loop into Effect.gen() generator.
+- **Assumption to validate**: Existing test files can be migrated to `it.effect()` without breaking.
+
+## Mathematical Guarantees (Proof Obligations)
+- Invariant: ∀f ∈ CORE: isPure(f) ∧ preservesInvariants(f)
+- ∀response: followsRoleSimulation(response) → contains(DeepResearchQuestion, response)
+- Variant: complexity decreases with each research → implementation → verification iteration.
+
+**Next Action (post-plan)**: Load this plan, begin step 1 with read-only inspection, then move to implementation turn.

+# Plan: MCP Playwright Integration for Hermes Agent (with noVNC compatibility)
+
+## Goal
+Study existing MCP Playwright connection in the Codex/docker-git setup (as referenced in README.md and e2e scripts), then create a precise replication plan for the Hermes Agent. Ensure seamless integration with the project's noVNC browser infrastructure so that MCP tools (launch, navigate, screenshot, interact) can control or coexist with the noVNC-exposed Chromium instance. The end result should make Playwright MCP tools first-class in Hermes (prefixed mcp_playwright_*) while preserving the Functional Core / Imperative Shell invariants from AGENTS.md.
+
+## Current Context / Assumptions
+- From read-only inspection (search_files for mcp|playwright|novnc|browser):
+  - README.md explicitly mentions `--mcp-playwright` flag that enables Playwright MCP + Chromium sidecar for browser automation.
+  - package.json has e2e:browser-command script and docker-git browser targets.
+  - docker-git clone command in README uses --mcp-playwright.
+  - No direct "hermes-browser" module found in top-level search, but browser toolset, CDP, and noVNC references exist in config and e2e scripts.
+  - Current ~/.hermes/config.yaml has no mcp_servers.playwright (or minimal from prior non-plan turns); native-mcp skill is available and documents exact YAML + hermes mcp add workflow.
+  - Codex integration likely lives in autonomous-ai-agents/codex or related docker-git patches/scripts (e2e/browser-command.sh, scripts/skiller-apply-docker-git-patches.mjs).
+  - noVNC is part of the browser sidecar (common pattern for remote VNC access to the Playwright-controlled browser).
+- Assumptions: Codex uses stdio transport via npx mcp-playwright (or equivalent bin mcp-server-playwright) with specific args for noVNC compatibility (headless=false, user-data-dir, cdp-endpoint, storage-state). Hermes can reuse the same MCP server config + Layer wrapping. The existing browser toolset (CDP/Camofox) can be composed with MCP.
+- Deep Research question simulated: "code that connects MCP Playwright to Codex/Hermes with noVNC" → patterns found in README + docker-git + native-mcp skill.
+
+## Proposed Approach
+- Reuse the exact MCP server definition from Codex/docker-git setup (npx -y mcp-playwright with flags for noVNC: --headless=false, --port for SSE, --user-data-dir shared with noVNC).
+- Wrap via native-mcp client (config.yaml mcp_servers.playwright + hermes mcp add/test/configure).
+- Create typed Effect Service Layer in CORE/SHELL boundary for mcp_playwright_* tools to maintain FCIS invariants.
+- Add noVNC coordination (shared profile/storage-state, CDP endpoint sharing).
+- Minimal diff: extend existing browser/e2e patterns rather than new from-scratch implementation.
+- All changes follow AGENTS.md: pure CORE functions for config validation/invariants, SHELL for actual MCP connection, exhaustive Match, formal TSDoc with invariants, property-based tests.
+
+## Step-by-Step Plan
+1. **Inspection Phase (read-only)**: 
+   - Read full README.md, docker-git related scripts (scripts/e2e/browser-command.sh, patches, docker-git/frontend-lib), packages/lib/src/core for existing browser/MCP patterns.
+   - Read current ~/.hermes/config.yaml (mcp_servers, browser, terminal sections).
+   - Search for Codex-specific MCP config (in autonomous-ai-agents/codex or kanban-codex-lane skills).
+2. **Formalization**: Define invariants (e.g. ∀ browser_session: connected_to_noVNC ∧ mcp_tools_available → coordinated_state).
+3. **Architecture**:
+   - Add mcp_servers.playwright entry matching Codex (command + args for noVNC compatibility).
+   - Create Shell Layer (PostgresMessageRepository-style) for MCP Playwright service.
+   - Update tool registry to expose prefixed tools.
+4. **noVNC Integration**: Ensure shared user-data-dir, CDP endpoint, or proxy so MCP controls the same browser instance exposed via noVNC.
+5. **Implementation** (post-plan turn): Apply minimal diff to config + new core/shell modules.
+6. **Verification**: Run hermes mcp test, e2e browser tests, architecture tests, property tests for invariants.
+
+## Files Likely to Change
+- .hermes/config.yaml (or via hermes mcp add) — add mcp_servers.playwright matching Codex pattern.
+- packages/lib/src/core/domain.ts or new packages/lib/src/core/mcp-playwright.ts (types, invariants, pure validators).
+- packages/lib/src/core/shell/mcp-layers.ts (Effect Layer for Playwright MCP service).
+- README.md or AGENTS.md (update integration notes).
+- scripts/e2e/browser-command.sh or new test script for noVNC + MCP coordination.
+- packages/lib/tests/usecases/mcp-playwright-integration.test.ts (new).
+- packages/lib/tests/architecture/fcis-boundary.test.ts (update to cover new MCP Layer).
+
+## Tests / Validation
+- **Property-based**: fc.assert on invariants (session shared between MCP and noVNC, no leaked effects in CORE).
+- **Integration**: `hermes mcp test playwright`, e2e/browser-command.sh with --mcp-playwright flag, manual noVNC connection test.
+- **Architecture**: lint + `npm test -- --grep="mcp|playwright|fcis|invariant"`, exhaustive pattern matching on tool results, no `any`/direct stdio in CORE.
+- **Verification commands** (future turns):
+  - `hermes mcp list && hermes mcp test playwright`
+  - `npm run lint && npm test`
+  - Grep for forbidden patterns in new core files.
+  - Visual confirmation: noVNC shows the same browser controlled by MCP tools.
+
+## Risks, Tradeoffs, and Open Questions
+- **Risk**: noVNC and MCP both trying to control the same browser instance → race conditions or session corruption. Mitigation: shared storage-state + CDP proxy.
+- **Tradeoff**: Reusing Codex/docker-git pattern minimizes diff but may inherit its quirks (0.0.1 package version, specific flags). Pure Hermes-native Layer is cleaner but larger change.
+- **Open Questions**:
+  - Exact args used in Codex/docker-git for noVNC (headless? port? allowed-origins? ) — needs deeper read of browser-command.sh and patches.
+  - Does "Hermes Browser" exist as a distinct skill/Layer or is it the existing browser toolset + CDP?
+  - How to formalize sampling (server-initiated LLM calls) from MCP Playwright in the Effect monad?
+  - Impact on existing browser toolset (CDP vs MCP overlap) — should one deprecate the other?
+- **Assumption to validate in step 1**: The `--mcp-playwright` in docker-git directly translates to a stdio MCP server config usable by Hermes native client.
+
+## Mathematical Guarantees
+- INVARIANT: ∀ session: (mcp_playwright_connected(session) ∧ noVNC_exposed(session)) → shared_user_data_dir(session) ∧ coordinated_cdp_endpoint(session)
+- PRE: mcp package installed ∧ npx mcp-playwright available.
+- POST: mcp_playwright_* tools registered and composable in Effect.gen() without breaking CORE purity.
+- FORMAT THEOREM: ∀x ∈ BrowserSessions: connected_via_mcp(x) → controllable_via_novnc(x)
+
+**REF**: Current conversation (MCP Playwright + noVNC request), native-mcp skill, AGENTS.md, README.md mentions of --mcp-playwright.
+**SOURCE**: n/a (project inspection via read-only search_files + read_file).
+**PURITY**: This plan document is pure (no effects).
+
+Next turn (after this plan): Execute inspection steps with read-only tools, then implement per this plan.

+# Plan: Clean Built-in Hermes Browser + noVNC Integration (No MCP Duplication)
+
+## Goal
+Remove all MCP Playwright references and duplication, making the built-in Hermes browser toolset the only browser backend. Configure it to connect directly to the existing `dg-docker-git-issue-347-browser` container (and similar per-issue containers) via CDP, ensuring a single unified browser session that is also accessible via noVNC. This follows the user's preference for the platform's out-of-the-box solution without duplicate tools.
+
+## Current Context / Assumptions
+- From read-only inspection (search_files for cdp_url|noVNC|browser|playwright|mcp_servers):
+  - `packages/lib/src/core/templates-entrypoint/hermes.ts` currently has MCP logic from previous changes.
+  - `packages/api/src/services/project-browser.ts` handles CDP proxying (cdpUrl, cdpPath, renderExternalUrl) for browser containers.
+  - Docker containers like `dg-docker-git-issue-347-browser` expose ports 5900 (VNC), 6080 (noVNC), 9223 (CDP).
+  - Config has `browser.cdp_url` and `browser.engine = cdp` set to localhost:9223.
+  - MCP was removed (`hermes mcp remove playwright`), no MCP servers or tools remain.
+  - README and templates for codex/claude/gemini still reference MCP Playwright — these should be left alone or cleaned only for Hermes path to avoid breaking other agents.
+- Assumption: The built-in browser tool can reliably use the CDP port of the per-issue browser container. noVNC is for viewing, CDP for control — single browser achieved via shared container.
+- Deep Research question: "code that configures Hermes built-in browser with noVNC/CDP without MCP" → patterns in project-browser.ts, hermes.ts, and docker container names.
+
+## Proposed Approach
+- Extend/clean `hermes.ts` template to always configure `browser.cdp_url` and `browser.engine = cdp` pointing to the project's browser container (using the same logic as project-browser.ts).
+- Remove any remaining MCP-related code from Hermes path (idempotent, no breaking changes to other agents).
+- Add formal invariants for single-browser guarantee.
+- No new files — minimal diff to existing template and tests.
+- Make CDP configuration part of the Hermes entrypoint render so it's automatic when --mcp-playwright is not used (or always for Hermes).
+
+## Step-by-Step Plan
+1. Read-only inspection: re-read hermes.ts, project-browser.ts, current ~/.hermes/config.yaml, and docker ps output for exact container/CDP pattern.
+2. Formalize invariants (single browser session, CDP connection succeeds, no MCP tools present).
+3. Update `packages/lib/src/core/templates-entrypoint/hermes.ts`:
+   - Add render function for CDP/noVNC configuration (mirroring project-browser.ts cdpUrl logic).
+   - Remove any leftover MCP code.
+   - Include formal TSDoc comment block.
+4. Update related test: `packages/lib/tests/usecases/...` or architecture test for template rendering.
+5. Verification: render the template, check generated bash contains correct cdp_url, run lint/test on the file, confirm no MCP in final config.
+
+## Files Likely to Change
+- `packages/lib/src/core/templates-entrypoint/hermes.ts` (main change — add CDP config render, remove MCP remnants).
+- `packages/lib/tests/usecases/template-rendering.test.ts` or similar (update expected output for Hermes entrypoint).
+- `packages/api/src/services/project-browser.ts` (if we need to expose more CDP helpers for Hermes — low probability).
+- No changes to codex.ts, claude.ts, or MCP-related files (preserve other agents).
+
+## Tests / Validation
+- **Unit**: Test `renderEntrypointHermesConfig` produces bash with `browser.cdp_url=http://localhost:9223` and `engine=cdp`.
+- **Integration**: Render full entrypoint, run in test container, verify `hermes tools list` shows only built-in browser (no mcp_playwright_*).
+- **Architecture**: Confirm no MCP imports/references in Hermes path, single-browser invariant holds (`cdp_url` matches container's 9223 port).
+- **Verification commands** (future turns, read-only where possible):
+  - `hermes tools list | grep -E 'browser|mcp'`
+  - `docker ps | grep browser`
+  - `npm run lint -- packages/lib/src/core/templates-entrypoint/hermes.ts`
+  - `npm test -- --grep="hermes|browser|cdp|template"`
+
+## Risks, Tradeoffs, and Open Questions
+- **Risk**: CDP connection to port 9223 may fail if the browser container is not running or port not exposed in current terminal context. Mitigation: fallback to local Chromium or explicit error in template.
+- **Tradeoff**: Losing MCP's advanced Playwright features (trace, better file handling, parallel execution) for simplicity and no duplication. Built-in browser is "коробочное" but less powerful.
+- **Open Questions**:
+  - Exact CDP WebSocket URL for the Cloudflare noVNC tunnel (is it always localhost:9223 or does it need external proxy like in project-browser.ts?).
+  - Should we add `--no-mcp` flag to docker-git for Hermes to make this default?
+  - How to handle noVNC viewing vs control — does built-in browser tool expose a noVNC link automatically?
+  - Impact on existing issue-347 Hermes support (need to update HERMES.md or docs?).
+- Assumption to validate in step 1: The dg-*-browser container's CDP port is reliably available at localhost:9223 from the main container.
+
+## Mathematical Guarantees
+- INVARIANT: ∀ hermes_session: (browser_tool_used(session) ∧ no_mcp_tools(session)) → connected_to_same_container_via_cdp(session) ∧ visible_in_noVNC(session)
+- PRE: docker container dg-*-browser running with port 9223 exposed.
+- POST: No duplicate browser tools in `hermes tools list`; single source of truth for browser = built-in + CDP.
+
+**REF**: Current conversation (duplication concern, noVNC, built-in preference), previous plan, project-browser.ts.
+**SOURCE**: n/a (read-only inspection of codebase and docker ps).
+**PURITY**: This plan is pure documentation.
+
+Next turn (after this plan): Execute read-only inspection steps, then implement the template update per this plan with minimal diff, followed by verification.

+# Plan: Rust-only noVNC + Browser Connection Module (Delete TS Version, Possible Separate Repo, Integrate into docker-git)
+
+## Goal
+Delete all TypeScript versions of the browser/noVNC connection (including the previous packages/browser-connection and lib/core version), keep only the Rust implementation in packages/rust-browser-connection (or move to separate repository), and update docker-git to use the Rust module/binary instead of the old MCP Playright + shell scripts. This eliminates duplication, makes the toolkit "из коробки" for both MCP-like and Hermes built-in browser tools, and follows issue #347.
+
+## Current Context / Assumptions
+- From read-only inspection (date, search_files for browser-connection|rust|novnc|mcp|playwright|cdp_url|dg-.*-browser, read_file for Cargo.toml, lib.rs, hermes.ts, project-browser.ts, pnpm-workspace.yaml, gh issue view 347):
+  - Rust package `packages/rust-browser-connection` exists with BrowserConnection (bollard for Docker, ports 5900/6080/9223, URLs, invariant).
+  - TS versions exist in packages/browser-connection (previous) and packages/lib/src/core/browser-connection.ts (duplicate).
+  - docker-git uses MCP Playright in templates-entrypoint (codex.ts, claude.ts, hermes.ts), project-browser.ts for CDP/noVNC proxy, docker-git-session-sync style.
+  - Issue #347 specifically asks to extract noVNC + MCP Playright into a single module for single browser with agent.
+  - Current docker containers (dg-docker-git-issue-347-browser) expose the ports.
+- Assumption: Rust binary can be called from TS entrypoints or docker images can include the Rust binary. Separate repo is feasible if maintenance is easier (as user suggested).
+- Deep Research question simulated: "code that extracts noVNC + browser connection to Rust module without duplication" → patterns in rust-browser-connection, project-browser-core.ts, templates-entrypoint, and the rust-ai-driven-development-pipeline-template.
+
+## Proposed Approach
+- Delete all TS versions and references to avoid duplication.
+- Keep/enhance the Rust package as the single source of truth (or move to separate repo like link-foundation style).
+- Update docker-git to call the Rust binary (or link the crate) for browser start, noVNC/CDP URLs, single session management — replacing old MCP/shell logic.
+- Make it "из коробки": the Rust module provides CLI and library, docker-git templates automatically use it when Hermes or other agents are selected.
+- Follow AGENTS.md for the Rust part (formal comments in code, invariants, tests, verification).
+
+## Step-by-step Plan
+1. Read-only inspection: full read of rust-browser-connection/Cargo.toml, src/lib.rs, src/main.rs, all templates-entrypoint/* .ts that mention MCP/playwright/browser, project-browser.ts, pnpm-workspace.yaml, gh issue view 347 for exact requirements, docker ps for current browser containers.
+2. Formalize: define invariants for single browser (one container, shared CDP/noVNC), types for URLs/ports, error handling.
+3. Delete TS version: plan removal of packages/browser-connection, packages/lib/src/core/browser-connection.ts, references in pnpm-workspace.yaml, hermes.ts, project-browser.ts, templates.
+4. Enhance Rust module: ensure it fully replicates docker-git MCP Playright behavior (start container with ports, return noVNC/CDP URLs, invariant check).
+5. Integration into docker-git: update entrypoints to call Rust binary (e.g. `docker-git-browser-connection start --project $(project_id)`), update docker compose to include Rust binary if needed.
+6. If separate repo: plan creating new repo, publishing the crate, updating docker-git to depend on it via cargo or binary download.
+7. Verification: cargo test, cargo check, test docker-git with Rust module, confirm no MCP/TS duplication, single noVNC browser works, lint/typecheck.
+
+## Files Likely to Change
+- Delete: packages/browser-connection/ (entire TS package), packages/lib/src/core/browser-connection.ts, references in pnpm-workspace.yaml.
+- Update: packages/lib/src/core/templates-entrypoint/hermes.ts (remove MCP, call Rust binary), packages/api/src/services/project-browser.ts (use Rust module for CDP/noVNC), packages/app/src/lib/core/templates-entrypoint/* (codex.ts, claude.ts if affected), docker-compose files or entrypoint scripts.
+- Rust package: packages/rust-browser-connection/src/lib.rs, Cargo.toml (add more features if needed for full docker-git compatibility).
+- Tests: packages/rust-browser-connection/tests/*, packages/lib/tests/usecases/browser-connection.test.ts (new for Rust integration).
+- Docs: README.md, issue #347 (close it), AGENTS.md (update for Rust module).
+
+## Tests / Validation
+- **Rust**: `cargo test`, `cargo check`, unit tests for isSingleBrowserSession, integration with mock Docker.
+- **docker-git**: Test with `docker-git clone <issue> --mcp-playwright` (should use Rust instead of old MCP), verify noVNC URL works, CDP port 9223 accessible, single container.
+- **Verification steps**:
+  - `cargo test` in rust-browser-connection.
+  - `hermes tools list` (no MCP, only built-in browser).
+  - `docker ps | grep browser` (single dg-*-browser container).
+  - `npm run lint && npm test` in root (no TS duplication errors).
+  - Manual test: open noVNC URL and use Hermes browser tool — same session.
+- Run in CI with the new Rust binary included in docker images.
+
+## Risks, Tradeoffs, and Open Questions
+- **Risk**: Removing TS version breaks existing users or MCP-dependent code in codex/claude templates. Mitigation: keep backward compatibility in templates or deprecate MCP path.
+- **Tradeoff**: Rust is faster and more reliable for Docker/container management, but adds Rust toolchain to the dev setup (vs pure TS "из коробки"). Separate repo adds maintenance but cleaner separation.
+- **Open Questions**:
+  - Separate repo or keep in monorepo? (user suggested separate — plan both options).
+  - How to package the Rust binary in docker-git images (static binary or cargo install)?
+  - Should the Rust module also handle MCP server registration or only the browser container/noVNC part?
+  - Exact mapping of old MCP Playright flags to Rust CLI args.
+  - CI/CD for Rust crate publishing and docker-git integration tests.
+- Assumption to validate in step 1: The Rust binary can fully replace the old shell/MCP logic without breaking noVNC viewing or agent control.
+
+## Mathematical Guarantees
+- INVARIANT: ∀ projectId: start_browser(projectId) → single_container(dg-{projectId}-browser) ∧ cdp_url(projectId) = "http://localhost:9223" ∧ no_vnc_url(projectId) matches template ∧ isSingleBrowserSession(cdp, novnc) = true
+- PRE: Docker daemon available, image dg-docker-git-browser available.
+- POST: No TS/MCP duplication, only Rust module used in docker-git and Hermes.
+
+**REF**: Current conversation + issue #347.
+**SOURCE**: n/a (read-only inspection of codebase, gh issue view, docker ps).
+**PURITY**: This plan is pure (no execution, only planning).
+
+Next turn (after this plan): Execute read-only inspection steps (gh issue view, read_file for key files, search_files for references), then delete TS version, enhance Rust package, integrate into docker-git per this plan (with verification).

+// CHANGE: extract noVNC + browser connection into reusable CORE module (issue #347)

+// QUOTE(ТЗ): "Я хочу вынести в отдельный модуль всё что связано с noVNC и подключенеим к браузеру. Хочу сделать так что бы из коробки можно было бы подключить как по MCP так к hermes tools browser"

+
+            This PR was created by a manual workflow trigger to prepare a **${{ github.event.inputs.bump_type }}** release.
+
+            ### Release Details
+            - **Type:** ${{ github.event.inputs.bump_type }}
+            - **Description:** ${{ github.event.inputs.description || 'Manual release' }}
+            - **Triggered by:** @${{ github.actor }}
+
+            ### Next Steps
+            1. Review the changelog fragment in this PR
+            2. Merge this PR to main
+            3. The automated release workflow will publish to crates.io and create a GitHub release
+
+  # === DEPLOY DOCUMENTATION ===
+  # Deploy Rust API documentation to GitHub Pages after a successful package build.
+  # Keep this independent from package/GitHub release publication so the website
+  # still updates when the release path fails. Use the official Pages artifact
+  # deployment path so repositories configured with "GitHub Actions" as their
+  # Pages source fail this job if Pages cannot deploy.
+  #
+  # One-time setup: in the repository's Settings -> Pages, set Source to
+  # "GitHub Actions". Without this, the first run fails on actions/deploy-pages
+  # with "Get Pages site failed" / "Failed to create deployment". This cannot be
+  # configured from a workflow. See README.md "Deploying API documentation".

+## [0.15.0] - 2026-05-16
+
+### Added
+- Changeset-style fragment format with frontmatter for specifying version bump type
+- New `get-bump-type.mjs` script to automatically determine version bump from fragments
+- Automatic version bumping on merge to main based on changelog fragments
+- Detailed documentation for the changelog fragment system in `changelog.d/README.md`
+
+### Changed
+- Updated `collect-changelog.mjs` to strip frontmatter when collecting fragments
+- Updated `version-and-commit.mjs` to handle frontmatter in fragments
+- Enhanced release workflow to automatically determine bump type from changesets
+
+### Changed
+- Add `detect-changes` job with cross-platform `detect-code-changes.mjs` script
+- Make lint job independent of changelog check (runs based on file changes only)
+- Allow docs-only PRs without changelog fragment requirement
+- Handle changelog check 'skipped' state in dependent jobs
+- Exclude `changelog.d/`, `docs/`, `experiments/`, `examples/` folders and markdown files from code changes detection
+
+### Fixed
+- Fixed README.md to correctly reference Node.js scripts (`.mjs`) instead of Python scripts (`.py`)
+- Updated project structure in README.md to match actual script files in `scripts/` directory
+- Fixed example code in README.md that had invalid Rust with two `main` functions
+
+### Added
+
+- Added crates.io publishing support to CI/CD workflow
+- Added `release_mode` input with "instant" and "changelog-pr" options for manual releases
+- Added `--tag-prefix` and `--crates-io-url` options to create-github-release.mjs script
+- Added comprehensive case study documentation for Issue #11 in docs/case-studies/issue-11/
+
+### Changed
+
+- Changed changelog fragment check from warning to error (exit 1) to enforce changelog requirements
+- Updated job conditions with `always() && !cancelled()` to fix workflow_dispatch job skipping issue
+- Renamed manual-release job to "Instant Release" for clarity
+
+### Fixed
+
+- Fixed deprecated `::set-output` GitHub Actions command in version-and-commit.mjs
+- Fixed workflow_dispatch triggering issues where lint/build/release jobs were incorrectly skipped
+
+### Fixed
+
+- Fixed changelog fragment check to validate that a fragment is **added in the PR diff** rather than just checking if any fragments exist in the directory. This prevents the check from incorrectly passing when there are leftover fragments from previous PRs that haven't been released yet.
+
+### Changed
+
+- Converted shell scripts in `release.yml` to cross-platform `.mjs` scripts for improved portability and performance:
+  - `check-changelog-fragment.mjs` - validates changelog fragment is added in PR diff
+  - `git-config.mjs` - configures git user for CI/CD
+  - `check-release-needed.mjs` - checks if release is needed
+  - `publish-crate.mjs` - publishes package to crates.io
+  - `create-changelog-fragment.mjs` - creates changelog fragments for manual releases
+  - `get-version.mjs` - gets current version from Cargo.toml
+
+### Added
+
+- Added `check-version-modification.mjs` script to detect manual version changes in Cargo.toml
+- Added `version-check` job to CI/CD workflow that runs on pull requests
+- Added skip logic for automated release branches (changelog-manual-release-*, changeset-release/*, release/*, automated-release/*)
+
+### Changed
+
+- Version modifications in Cargo.toml are now blocked in pull requests to enforce automated release pipeline
+
+### Added
+
+- Added support for `CARGO_REGISTRY_TOKEN` as alternative to `CARGO_TOKEN` for crates.io publishing
+- Added case study documentation for Issue #17 (yargs reserved word and dual token support)
+
+### Changed
+
+- Updated workflow to use fallback logic: `${{ secrets.CARGO_REGISTRY_TOKEN || secrets.CARGO_TOKEN }}`
+- Improved publish-crate.mjs to check both `CARGO_REGISTRY_TOKEN` and `CARGO_TOKEN` environment variables
+- Added warning message when neither token is set
+
+### Added
+- New `scripts/rust-paths.mjs` utility for automatic Rust package root detection
+- Support for both single-language and multi-language repository structures in all CI/CD scripts
+- Configuration options via `--rust-root` CLI argument and `RUST_ROOT` environment variable
+- Comprehensive case study documentation in `docs/case-studies/issue-19/`
+
+### Changed
+- Updated all release scripts to use the new path detection utility:
+  - `scripts/bump-version.mjs`
+  - `scripts/check-release-needed.mjs`
+  - `scripts/collect-changelog.mjs`
+  - `scripts/get-bump-type.mjs`
+  - `scripts/get-version.mjs`
+  - `scripts/publish-crate.mjs`
+  - `scripts/version-and-commit.mjs`
+
+### Changed
+
+- **check-release-needed.mjs**: Now checks crates.io API directly instead of git tags to determine if a version is already released. This prevents false positives where git tags exist but the package was never actually published to crates.io.
+
+### Added
+
+- **CI/CD Troubleshooting Guide**: New documentation at `docs/ci-cd/troubleshooting.md` covering common issues like skipped jobs, false positive version checks, publishing failures, and secret configuration.
+
+- **Enhanced Error Handling in publish-crate.mjs**: Added specific detection and helpful error messages for authentication failures, including guidance on secret configuration and workflow setup.
+
+- **Case Study Documentation**: Added comprehensive case study at `docs/case-studies/issue-21/` analyzing CI/CD failures from browser-commander repository (issues #27, #29, #31, #33) with timeline, root causes, and lessons learned.
+
+### Fixed
+
+- **Prevent False Positive Version Checks**: The release workflow now correctly identifies unpublished versions by checking crates.io instead of relying on git tags, which can exist without the package being published.
+
+### Changed
+
+- Translated all CI/CD scripts from JavaScript (.mjs) to Rust (.rs) using rust-script
+- Scripts now use native Rust with rust-script for execution in shell
+- Removed Node.js dependency from CI/CD pipeline
+- Updated GitHub Actions workflow to use rust-script instead of node
+- Updated README and CONTRIBUTING documentation with new script references
+
+### Added
+
+- Cache `restore-keys` for partial cache hits across all workflow jobs
+- Explicit `token` parameter in checkout for release jobs
+- Code coverage job with `cargo-llvm-cov` and Codecov integration
+- Codecov badge in README.md
+- Pre-release version support (e.g., `0.1.0-beta.1`) in version parsing
+- `--release-label` parameter for multi-language release disambiguation
+- `ensure_version_exceeds_published()` logic to prevent publishing duplicate versions
+- `get_max_published_version()` to query highest non-yanked version from crates.io
+- `max_published_version` output from check-release-needed for downstream use
+- Version fallback logic in auto-release Create GitHub Release step
+
+### Changed
+
+- Updated `actions/checkout` from v4 to v6
+- Updated `actions/cache` from v4 to v5
+- Updated `peter-evans/create-pull-request` from v7 to v8
+- Made `publish-crate.rs` fail (exit 1) when version already exists on crates.io
+- Improved `create-github-release.rs` to check combined stdout+stderr and detect "Validation Failed"
+
+### Fixed
+
+- Fix publish steps overriding workflow-level CARGO_TOKEN fallback, breaking CARGO_REGISTRY_TOKEN-only configurations (#32)
+- Fix non-fast-forward push failures in multi-workflow repos by adding fetch/rebase and push retry logic (#31)
+- Add mono-repo path support to check-changelog-fragment.rs, check-version-modification.rs, and create-changelog-fragment.rs
+- Add `!cancelled()` guard to test job condition to respect workflow cancellation
+
+### Fixed
+
+- Fixed `version-and-commit.rs` to check crates.io instead of git tags for determining if a version is already released
+- This prevents the release pipeline from getting stuck when git tags exist without corresponding crates.io publication
+
+### Added
+
+- Added `--tag-prefix` support to `version-and-commit.rs` for multi-language repository compatibility
+- Added crates.io and docs.rs badges to README.md
+- Added automatic crates.io and docs.rs badge injection in GitHub release notes
+- Added documentation deployment job to CI/CD pipeline (deploys to GitHub Pages after release)
+- Added case study documentation for issue #25
+
+### Fixed
+- Fixed unsupported look-ahead regex in `create-github-release.rs` that caused a panic when parsing CHANGELOG.md. Replaced with a two-step approach using only features supported by Rust's `regex` crate.
+
+### Changed
+- Restructured example application as a simple CLI sum calculator using `lino-arguments`
+- Renamed default package to `example-sum-package-name` with Unlicense license
+- Reorganized test structure: `tests/unit/sum.rs`, `tests/integration/sum.rs`, `tests/unit/ci-cd/`
+- Converted experiment scripts into proper unit tests in `tests/unit/ci-cd/changelog_parsing.rs`
+- Added CI/CD skip logic for template default package name `example-sum-package-name`
+- Updated README.md badges and documentation
+
+### Fixed
+
+- Change detection script now uses per-commit diff instead of full PR diff, so commits touching only non-code files correctly skip CI jobs even when earlier commits in the same PR changed code files
+
+### Fixed
+- Make release scripts resolve the publishable crate manifest when the repository root uses a Cargo workspace manifest.
+
+### Fixed
+- Decoupled GitHub Pages documentation deployment from package release publication and fixed release-script warning failures under `RUSTFLAGS=-Dwarnings`.
+
+### Changed
+- Added explicit GitHub Actions job timeouts and documented Rust test timeout guidance.
+
+### Fixed
+- Added a non-blocking warning threshold to the Rust file-size check so near-limit files are surfaced before concurrent PR merges can exceed the hard limit.
+
+### Fixed
+- Made `create-github-release.rs` build GitHub release titles as `[Language] X.Y.Z` instead of reusing the tag prefix.
+
+### Added
+- Added optional Docker Hub image publishing tied to Rust crate releases, including crates.io visibility waiting, version/latest image tags, and Docker Hub badges in GitHub release notes.
+
+### Changed
+- Release completeness checks now self-heal when crates.io exists but configured Docker Hub or GitHub release artifacts are missing.
+
+### Fixed
+- Switched documentation deployment to the official GitHub Pages artifact workflow so repositories using GitHub Actions as their Pages source do not get false-positive branch-push deploys.
+
+### Added
+- Documented the one-time `Settings → Pages → Source = GitHub Actions` prerequisite for the `deploy-docs` job in `README.md` and as a comment above the `deploy-docs` job in `release.yml`, so downstream template users hit a documented setup step instead of a `Get Pages site failed` error on the first deploy.
+
+### Added
+- Tracking case study at `docs/case-studies/issue-52/` registering the `browser-commander` + Playwright preview-regeneration pattern from [`konard/vk-bot-desktop#52`](https://github.com/konard/vk-bot-desktop/pull/52), with an activation checklist for when an example-app surface lands in this template. Documentation only — no workflow, script, or runtime code changes. Primary upstream tracking issue: [`link-foundation/js-ai-driven-development-pipeline-template#62`](https://github.com/link-foundation/js-ai-driven-development-pipeline-template/issues/62).
+
+### Fixed
+- Release automation now keeps the workspace package entry in `Cargo.lock` synchronized when `scripts/version-and-commit.rs` bumps `Cargo.toml`, preventing stale lock-file version diffs in later pull requests.

+- Made `publish-crate.rs` fail (exit 1) when version already exists on crates.io
+- Improved `create-github-release.rs` to check combined stdout+stderr and detect "Validation Failed"
+
+### Fixed
+
+- Fix publish steps overriding workflow-level CARGO_TOKEN fallback, breaking CARGO_REGISTRY_TOKEN-only configurations (#32)
+- Fix non-fast-forward push failures in multi-workflow repos by adding fetch/rebase and push retry logic (#31)
+- Add mono-repo path support to check-changelog-fragment.rs, check-version-modification.rs, and create-changelog-fragment.rs
+- Add `!cancelled()` guard to test job condition to respect workflow cancellation
+
+### Fixed
+
+- Fixed `version-and-commit.rs` to check crates.io instead of git tags for determining if a version is already released
+- This prevents the release pipeline from getting stuck when git tags exist without corresponding crates.io publication
+
+### Added
+
+- Added `--tag-prefix` support to `version-and-commit.rs` for multi-language repository compatibility
+- Added crates.io and docs.rs badges to README.md
+- Added automatic crates.io and docs.rs badge injection in GitHub release notes
+- Added documentation deployment job to CI/CD pipeline (deploys to GitHub Pages after release)
+- Added case study documentation for issue #25
+
+### Fixed
+- Fixed unsupported look-ahead regex in `create-github-release.rs` that caused a panic when parsing CHANGELOG.md. Replaced with a two-step approach using only features supported by Rust's `regex` crate.
+
+### Changed
+- Restructured example application as a simple CLI sum calculator using `lino-arguments`
+- Renamed default package to `example-sum-package-name` with Unlicense license
+- Reorganized test structure: `tests/unit/sum.rs`, `tests/integration/sum.rs`, `tests/unit/ci-cd/`

+- Added CI/CD skip logic for template default package name `example-sum-package-name`
+- Updated README.md badges and documentation
+
+### Fixed
+
+- Change detection script now uses per-commit diff instead of full PR diff, so commits touching only non-code files correctly skip CI jobs even when earlier commits in the same PR changed code files
+
+### Fixed
+- Make release scripts resolve the publishable crate manifest when the repository root uses a Cargo workspace manifest.
+
+### Fixed
+- Decoupled GitHub Pages documentation deployment from package release publication and fixed release-script warning failures under `RUSTFLAGS=-Dwarnings`.
+
+### Changed
+- Added explicit GitHub Actions job timeouts and documented Rust test timeout guidance.
+
+### Fixed
+- Added a non-blocking warning threshold to the Rust file-size check so near-limit files are surfaced before concurrent PR merges can exceed the hard limit.
+
+### Fixed
+- Made `create-github-release.rs` build GitHub release titles as `[Language] X.Y.Z` instead of reusing the tag prefix.
+
+### Added
+- Added optional Docker Hub image publishing tied to Rust crate releases, including crates.io visibility waiting, version/latest image tags, and Docker Hub badges in GitHub release notes.
+
+### Changed
+- Release completeness checks now self-heal when crates.io exists but configured Docker Hub or GitHub release artifacts are missing.
+
+### Fixed
+- Switched documentation deployment to the official GitHub Pages artifact workflow so repositories using GitHub Actions as their Pages source do not get false-positive branch-push deploys.
+
+### Added
+- Documented the one-time `Settings → Pages → Source = GitHub Actions` prerequisite for the `deploy-docs` job in `README.md` and as a comment above the `deploy-docs` job in `release.yml`, so downstream template users hit a documented setup step instead of a `Get Pages site failed` error on the first deploy.
+
+## [0.12.0] - 2026-05-12
+
+### Added
+- Changeset-style fragment format with frontmatter for specifying version bump type

+- Make lint job independent of changelog check (runs based on file changes only)
+- Allow docs-only PRs without changelog fragment requirement
+- Handle changelog check 'skipped' state in dependent jobs
+- Exclude `changelog.d/`, `docs/`, `experiments/`, `examples/` folders and markdown files from code changes detection
+
+### Fixed
+- Fixed README.md to correctly reference Node.js scripts (`.mjs`) instead of Python scripts (`.py`)
+- Updated project structure in README.md to match actual script files in `scripts/` directory
+- Fixed example code in README.md that had invalid Rust with two `main` functions
+
+### Added
+
+- Added crates.io publishing support to CI/CD workflow
+- Added `release_mode` input with "instant" and "changelog-pr" options for manual releases
+- Added `--tag-prefix` and `--crates-io-url` options to create-github-release.mjs script
+- Added comprehensive case study documentation for Issue #11 in docs/case-studies/issue-11/
+
+### Changed
+
+- Changed changelog fragment check from warning to error (exit 1) to enforce changelog requirements
+- Updated job conditions with `always() && !cancelled()` to fix workflow_dispatch job skipping issue
+- Renamed manual-release job to "Instant Release" for clarity
+
+### Fixed
+
+- Fixed deprecated `::set-output` GitHub Actions command in version-and-commit.mjs
+- Fixed workflow_dispatch triggering issues where lint/build/release jobs were incorrectly skipped
+
+### Fixed
+
+- Fixed changelog fragment check to validate that a fragment is **added in the PR diff** rather than just checking if any fragments exist in the directory. This prevents the check from incorrectly passing when there are leftover fragments from previous PRs that haven't been released yet.
+
+### Changed
+
+- Converted shell scripts in `release.yml` to cross-platform `.mjs` scripts for improved portability and performance:
+  - `check-changelog-fragment.mjs` - validates changelog fragment is added in PR diff
+  - `git-config.mjs` - configures git user for CI/CD
+  - `check-release-needed.mjs` - checks if release is needed
+  - `publish-crate.mjs` - publishes package to crates.io
+  - `create-changelog-fragment.mjs` - creates changelog fragments for manual releases
+  - `get-version.mjs` - gets current version from Cargo.toml
+
+### Added
+
+- Added `check-version-modification.mjs` script to detect manual version changes in Cargo.toml
+- Added `version-check` job to CI/CD workflow that runs on pull requests
+- Added skip logic for automated release branches (changelog-manual-release-*, changeset-release/*, release/*, automated-release/*)
+
+### Changed
+
+- Version modifications in Cargo.toml are now blocked in pull requests to enforce automated release pipeline
+
+### Added
+
+- Added support for `CARGO_REGISTRY_TOKEN` as alternative to `CARGO_TOKEN` for crates.io publishing
+- Added case study documentation for Issue #17 (yargs reserved word and dual token support)
+
+### Changed
+
+- Updated workflow to use fallback logic: `${{ secrets.CARGO_REGISTRY_TOKEN || secrets.CARGO_TOKEN }}`
+- Improved publish-crate.mjs to check both `CARGO_REGISTRY_TOKEN` and `CARGO_TOKEN` environment variables
+- Added warning message when neither token is set
+
+### Added
+- New `scripts/rust-paths.mjs` utility for automatic Rust package root detection

+- Comprehensive case study documentation in `docs/case-studies/issue-19/`
+
+### Changed
+- Updated all release scripts to use the new path detection utility:
+  - `scripts/bump-version.mjs`
+  - `scripts/check-release-needed.mjs`
+  - `scripts/collect-changelog.mjs`
+  - `scripts/get-bump-type.mjs`
+  - `scripts/get-version.mjs`
+  - `scripts/publish-crate.mjs`
+  - `scripts/version-and-commit.mjs`
+
+### Changed
+
+- **check-release-needed.mjs**: Now checks crates.io API directly instead of git tags to determine if a version is already released. This prevents false positives where git tags exist but the package was never actually published to crates.io.
+
+### Added
+
+- **CI/CD Troubleshooting Guide**: New documentation at `docs/ci-cd/troubleshooting.md` covering common issues like skipped jobs, false positive version checks, publishing failures, and secret configuration.
+
+- **Enhanced Error Handling in publish-crate.mjs**: Added specific detection and helpful error messages for authentication failures, including guidance on secret configuration and workflow setup.
+
+- **Case Study Documentation**: Added comprehensive case study at `docs/case-studies/issue-21/` analyzing CI/CD failures from browser-commander repository (issues #27, #29, #31, #33) with timeline, root causes, and lessons learned.
+
+### Fixed
+
+- **Prevent False Positive Version Checks**: The release workflow now correctly identifies unpublished versions by checking crates.io instead of relying on git tags, which can exist without the package being published.
+
+### Changed
+
+- Translated all CI/CD scripts from JavaScript (.mjs) to Rust (.rs) using rust-script
+- Scripts now use native Rust with rust-script for execution in shell

+
+### Fixed
+- Make release scripts resolve the publishable crate manifest when the repository root uses a Cargo workspace manifest.
+
+### Fixed
+- Decoupled GitHub Pages documentation deployment from package release publication and fixed release-script warning failures under `RUSTFLAGS=-Dwarnings`.
+
+### Changed
+- Added explicit GitHub Actions job timeouts and documented Rust test timeout guidance.
+
+### Fixed
+- Added a non-blocking warning threshold to the Rust file-size check so near-limit files are surfaced before concurrent PR merges can exceed the hard limit.
+
+### Fixed
+- Made `create-github-release.rs` build GitHub release titles as `[Language] X.Y.Z` instead of reusing the tag prefix.
+
+## [0.9.0] - 2026-05-03
+
+### Added
+- Changeset-style fragment format with frontmatter for specifying version bump type
+- New `get-bump-type.mjs` script to automatically determine version bump from fragments
+- Automatic version bumping on merge to main based on changelog fragments
+- Detailed documentation for the changelog fragment system in `changelog.d/README.md`
+
+### Changed
+- Updated `collect-changelog.mjs` to strip frontmatter when collecting fragments
+- Updated `version-and-commit.mjs` to handle frontmatter in fragments
+- Enhanced release workflow to automatically determine bump type from changesets
+
+### Changed
+- Add `detect-changes` job with cross-platform `detect-code-changes.mjs` script
+- Make lint job independent of changelog check (runs based on file changes only)
+- Allow docs-only PRs without changelog fragment requirement
+- Handle changelog check 'skipped' state in dependent jobs
+- Exclude `changelog.d/`, `docs/`, `experiments/`, `examples/` folders and markdown files from code changes detection
+
+### Fixed
+- Fixed README.md to correctly reference Node.js scripts (`.mjs`) instead of Python scripts (`.py`)
+- Updated project structure in README.md to match actual script files in `scripts/` directory
+- Fixed example code in README.md that had invalid Rust with two `main` functions
+
+### Added
+
+- Added crates.io publishing support to CI/CD workflow
+- Added `release_mode` input with "instant" and "changelog-pr" options for manual releases
+- Added `--tag-prefix` and `--crates-io-url` options to create-github-release.mjs script
+- Added comprehensive case study documentation for Issue #11 in docs/case-studies/issue-11/
+
+### Changed
+
+- Changed changelog fragment check from warning to error (exit 1) to enforce changelog requirements
+- Updated job conditions with `always() && !cancelled()` to fix workflow_dispatch job skipping issue
+- Renamed manual-release job to "Instant Release" for clarity
+
+### Fixed
+
+- Fixed deprecated `::set-output` GitHub Actions command in version-and-commit.mjs
+- Fixed workflow_dispatch triggering issues where lint/build/release jobs were incorrectly skipped
+
+### Fixed
+
+- Fixed changelog fragment check to validate that a fragment is **added in the PR diff** rather than just checking if any fragments exist in the directory. This prevents the check from incorrectly passing when there are leftover fragments from previous PRs that haven't been released yet.
+
+### Changed
+
+- Converted shell scripts in `release.yml` to cross-platform `.mjs` scripts for improved portability and performance:
+  - `check-changelog-fragment.mjs` - validates changelog fragment is added in PR diff
+  - `git-config.mjs` - configures git user for CI/CD
+  - `check-release-needed.mjs` - checks if release is needed
+  - `publish-crate.mjs` - publishes package to crates.io
+  - `create-changelog-fragment.mjs` - creates changelog fragments for manual releases
+  - `get-version.mjs` - gets current version from Cargo.toml
+
+### Added
+
+- Added `check-version-modification.mjs` script to detect manual version changes in Cargo.toml
+- Added `version-check` job to CI/CD workflow that runs on pull requests
+- Added skip logic for automated release branches (changelog-manual-release-*, changeset-release/*, release/*, automated-release/*)
+
+### Changed
+
+- Version modifications in Cargo.toml are now blocked in pull requests to enforce automated release pipeline
+
+### Added
+
+- Added support for `CARGO_REGISTRY_TOKEN` as alternative to `CARGO_TOKEN` for crates.io publishing
+- Added case study documentation for Issue #17 (yargs reserved word and dual token support)
+
+### Changed
+
+- Updated workflow to use fallback logic: `${{ secrets.CARGO_REGISTRY_TOKEN || secrets.CARGO_TOKEN }}`
+- Improved publish-crate.mjs to check both `CARGO_REGISTRY_TOKEN` and `CARGO_TOKEN` environment variables
+- Added warning message when neither token is set
+
+### Added
+- New `scripts/rust-paths.mjs` utility for automatic Rust package root detection
+- Support for both single-language and multi-language repository structures in all CI/CD scripts
+- Configuration options via `--rust-root` CLI argument and `RUST_ROOT` environment variable
+- Comprehensive case study documentation in `docs/case-studies/issue-19/`
+
+### Changed
+- Updated all release scripts to use the new path detection utility:
+  - `scripts/bump-version.mjs`
+  - `scripts/check-release-needed.mjs`
+  - `scripts/collect-changelog.mjs`
+  - `scripts/get-bump-type.mjs`
+  - `scripts/get-version.mjs`
+  - `scripts/publish-crate.mjs`
+  - `scripts/version-and-commit.mjs`
+
+### Changed
+
+- **check-release-needed.mjs**: Now checks crates.io API directly instead of git tags to determine if a version is already released. This prevents false positives where git tags exist but the package was never actually published to crates.io.
+
+### Added
+
+- **CI/CD Troubleshooting Guide**: New documentation at `docs/ci-cd/troubleshooting.md` covering common issues like skipped jobs, false positive version checks, publishing failures, and secret configuration.
+
+- **Enhanced Error Handling in publish-crate.mjs**: Added specific detection and helpful error messages for authentication failures, including guidance on secret configuration and workflow setup.
+
+- **Case Study Documentation**: Added comprehensive case study at `docs/case-studies/issue-21/` analyzing CI/CD failures from browser-commander repository (issues #27, #29, #31, #33) with timeline, root causes, and lessons learned.
+
+### Fixed
+
+- **Prevent False Positive Version Checks**: The release workflow now correctly identifies unpublished versions by checking crates.io instead of relying on git tags, which can exist without the package being published.
+
+### Changed
+
+- Translated all CI/CD scripts from JavaScript (.mjs) to Rust (.rs) using rust-script

+- Add `!cancelled()` guard to test job condition to respect workflow cancellation
+
+### Fixed
+

+
+## [0.6.0] - 2026-04-13
+
+### Added
+- Changeset-style fragment format with frontmatter for specifying version bump type

+- Handle changelog check 'skipped' state in dependent jobs
+- Exclude `changelog.d/`, `docs/`, `experiments/`, `examples/` folders and markdown files from code changes detection
+
+### Fixed

+- Added `release_mode` input with "instant" and "changelog-pr" options for manual releases
+- Added `--tag-prefix` and `--crates-io-url` options to create-github-release.mjs script
+- Added comprehensive case study documentation for Issue #11 in docs/case-studies/issue-11/
+
+### Changed
+
+- Changed changelog fragment check from warning to error (exit 1) to enforce changelog requirements
+- Updated job conditions with `always() && !cancelled()` to fix workflow_dispatch job skipping issue
+- Renamed manual-release job to "Instant Release" for clarity
+
+### Fixed
+
+- Fixed deprecated `::set-output` GitHub Actions command in version-and-commit.mjs
+- Fixed workflow_dispatch triggering issues where lint/build/release jobs were incorrectly skipped
+
+### Fixed
+
+- Fixed changelog fragment check to validate that a fragment is **added in the PR diff** rather than just checking if any fragments exist in the directory. This prevents the check from incorrectly passing when there are leftover fragments from previous PRs that haven't been released yet.
+
+### Changed
+
+- Converted shell scripts in `release.yml` to cross-platform `.mjs` scripts for improved portability and performance:
+  - `check-changelog-fragment.mjs` - validates changelog fragment is added in PR diff
+  - `git-config.mjs` - configures git user for CI/CD
+  - `check-release-needed.mjs` - checks if release is needed
+  - `publish-crate.mjs` - publishes package to crates.io
+  - `create-changelog-fragment.mjs` - creates changelog fragments for manual releases
+  - `get-version.mjs` - gets current version from Cargo.toml
+
+### Added
+
+- Added `check-version-modification.mjs` script to detect manual version changes in Cargo.toml
+- Added `version-check` job to CI/CD workflow that runs on pull requests
+- Added skip logic for automated release branches (changelog-manual-release-*, changeset-release/*, release/*, automated-release/*)
+
+### Changed
+
+- Version modifications in Cargo.toml are now blocked in pull requests to enforce automated release pipeline
+
+### Added
+
+- Added support for `CARGO_REGISTRY_TOKEN` as alternative to `CARGO_TOKEN` for crates.io publishing
+- Added case study documentation for Issue #17 (yargs reserved word and dual token support)
+
+### Changed
+
+- Updated workflow to use fallback logic: `${{ secrets.CARGO_REGISTRY_TOKEN || secrets.CARGO_TOKEN }}`
+- Improved publish-crate.mjs to check both `CARGO_REGISTRY_TOKEN` and `CARGO_TOKEN` environment variables
+- Added warning message when neither token is set
+
+### Added
+- New `scripts/rust-paths.mjs` utility for automatic Rust package root detection

+- Comprehensive case study documentation in `docs/case-studies/issue-19/`
+
+### Changed

+  - `scripts/get-bump-type.mjs`
+  - `scripts/get-version.mjs`
+  - `scripts/publish-crate.mjs`
+  - `scripts/version-and-commit.mjs`
+
+### Changed
+
+- **check-release-needed.mjs**: Now checks crates.io API directly instead of git tags to determine if a version is already released. This prevents false positives where git tags exist but the package was never actually published to crates.io.
+
+### Added
+
+- **CI/CD Troubleshooting Guide**: New documentation at `docs/ci-cd/troubleshooting.md` covering common issues like skipped jobs, false positive version checks, publishing failures, and secret configuration.

+
+### Fixed
+
+- **Prevent False Positive Version Checks**: The release workflow now correctly identifies unpublished versions by checking crates.io instead of relying on git tags, which can exist without the package being published.
+
+### Changed
+
+- Translated all CI/CD scripts from JavaScript (.mjs) to Rust (.rs) using rust-script
+- Scripts now use native Rust with rust-script for execution in shell

+  - `check-changelog-fragment.mjs` - validates changelog fragment is added in PR diff
+  - `git-config.mjs` - configures git user for CI/CD
+  - `check-release-needed.mjs` - checks if release is needed
+  - `publish-crate.mjs` - publishes package to crates.io
+  - `create-changelog-fragment.mjs` - creates changelog fragments for manual releases
+  - `get-version.mjs` - gets current version from Cargo.toml
+
+### Added
+
+- Added `check-version-modification.mjs` script to detect manual version changes in Cargo.toml
+- Added `version-check` job to CI/CD workflow that runs on pull requests
+- Added skip logic for automated release branches (changelog-manual-release-*, changeset-release/*, release/*, automated-release/*)
+
+### Changed
+
+- Version modifications in Cargo.toml are now blocked in pull requests to enforce automated release pipeline
+
+### Added
+
+- Added support for `CARGO_REGISTRY_TOKEN` as alternative to `CARGO_TOKEN` for crates.io publishing
+- Added case study documentation for Issue #17 (yargs reserved word and dual token support)
+
+### Changed
+
+- Updated workflow to use fallback logic: `${{ secrets.CARGO_REGISTRY_TOKEN || secrets.CARGO_TOKEN }}`
+- Improved publish-crate.mjs to check both `CARGO_REGISTRY_TOKEN` and `CARGO_TOKEN` environment variables
+- Added warning message when neither token is set
+
+### Added
+- New `scripts/rust-paths.mjs` utility for automatic Rust package root detection
+- Support for both single-language and multi-language repository structures in all CI/CD scripts
+- Configuration options via `--rust-root` CLI argument and `RUST_ROOT` environment variable
+- Comprehensive case study documentation in `docs/case-studies/issue-19/`
+
+### Changed
+- Updated all release scripts to use the new path detection utility:
+  - `scripts/bump-version.mjs`
+  - `scripts/check-release-needed.mjs`
+  - `scripts/collect-changelog.mjs`
+  - `scripts/get-bump-type.mjs`
+  - `scripts/get-version.mjs`
+  - `scripts/publish-crate.mjs`
+  - `scripts/version-and-commit.mjs`
+
+### Changed
+
+- **check-release-needed.mjs**: Now checks crates.io API directly instead of git tags to determine if a version is already released. This prevents false positives where git tags exist but the package was never actually published to crates.io.
+
+### Added
+
+- **CI/CD Troubleshooting Guide**: New documentation at `docs/ci-cd/troubleshooting.md` covering common issues like skipped jobs, false positive version checks, publishing failures, and secret configuration.
+
+- **Enhanced Error Handling in publish-crate.mjs**: Added specific detection and helpful error messages for authentication failures, including guidance on secret configuration and workflow setup.
+
+- **Case Study Documentation**: Added comprehensive case study at `docs/case-studies/issue-21/` analyzing CI/CD failures from browser-commander repository (issues #27, #29, #31, #33) with timeline, root causes, and lessons learned.
+
+### Fixed
+
+- **Prevent False Positive Version Checks**: The release workflow now correctly identifies unpublished versions by checking crates.io instead of relying on git tags, which can exist without the package being published.
+
+### Changed
+
+- Translated all CI/CD scripts from JavaScript (.mjs) to Rust (.rs) using rust-script
+- Scripts now use native Rust with rust-script for execution in shell
+- Removed Node.js dependency from CI/CD pipeline
+- Updated GitHub Actions workflow to use rust-script instead of node
+- Updated README and CONTRIBUTING documentation with new script references
+
+### Fixed
+
+- Fixed `version-and-commit.rs` to check crates.io instead of git tags for determining if a version is already released
+- This prevents the release pipeline from getting stuck when git tags exist without corresponding crates.io publication
+
+### Added
+
+- Added `--tag-prefix` support to `version-and-commit.rs` for multi-language repository compatibility
+- Added crates.io and docs.rs badges to README.md
+- Added automatic crates.io and docs.rs badge injection in GitHub release notes
+- Added documentation deployment job to CI/CD pipeline (deploys to GitHub Pages after release)
+- Added case study documentation for issue #25
+
+## [0.2.0] - 2026-03-11
+
+### Added
+- Changeset-style fragment format with frontmatter for specifying version bump type
+- New `get-bump-type.mjs` script to automatically determine version bump from fragments
+- Automatic version bumping on merge to main based on changelog fragments
+- Detailed documentation for the changelog fragment system in `changelog.d/README.md`
+
+### Changed
+- Updated `collect-changelog.mjs` to strip frontmatter when collecting fragments
+- Updated `version-and-commit.mjs` to handle frontmatter in fragments
+- Enhanced release workflow to automatically determine bump type from changesets
+
+### Changed
+- Add `detect-changes` job with cross-platform `detect-code-changes.mjs` script
+- Make lint job independent of changelog check (runs based on file changes only)
+- Allow docs-only PRs without changelog fragment requirement
+- Handle changelog check 'skipped' state in dependent jobs
+- Exclude `changelog.d/`, `docs/`, `experiments/`, `examples/` folders and markdown files from code changes detection
+
+### Fixed
+- Fixed README.md to correctly reference Node.js scripts (`.mjs`) instead of Python scripts (`.py`)
+- Updated project structure in README.md to match actual script files in `scripts/` directory
+- Fixed example code in README.md that had invalid Rust with two `main` functions
+
+### Added
+
+- Added crates.io publishing support to CI/CD workflow
+- Added `release_mode` input with "instant" and "changelog-pr" options for manual releases
+- Added `--tag-prefix` and `--crates-io-url` options to create-github-release.mjs script
+- Added comprehensive case study documentation for Issue #11 in docs/case-studies/issue-11/
+
+### Changed
+
+- Changed changelog fragment check from warning to error (exit 1) to enforce changelog requirements
+- Updated job conditions with `always() && !cancelled()` to fix workflow_dispatch job skipping issue
+- Renamed manual-release job to "Instant Release" for clarity
+
+### Fixed
+
+- Fixed deprecated `::set-output` GitHub Actions command in version-and-commit.mjs
+- Fixed workflow_dispatch triggering issues where lint/build/release jobs were incorrectly skipped
+
+### Fixed
+
+- Fixed changelog fragment check to validate that a fragment is **added in the PR diff** rather than just checking if any fragments exist in the directory. This prevents the check from incorrectly passing when there are leftover fragments from previous PRs that haven't been released yet.
+
+### Changed
+
+- Converted shell scripts in `release.yml` to cross-platform `.mjs` scripts for improved portability and performance:
+  - `check-changelog-fragment.mjs` - validates changelog fragment is added in PR diff
+  - `git-config.mjs` - configures git user for CI/CD
+  - `check-release-needed.mjs` - checks if release is needed

+# Contributing to rust-ai-driven-development-pipeline-template
+
+Thank you for your interest in contributing! This document provides guidelines and instructions for contributing to this project.
+
+## Development Setup
+
+1. **Fork and clone the repository**
+
+   ```bash
+   git clone https://github.com/YOUR-USERNAME/rust-ai-driven-development-pipeline-template.git
+   cd rust-ai-driven-development-pipeline-template
+   ```
+
+2. **Install Rust**
+
+   Install Rust using rustup (if not already installed):
+
+   ```bash
+   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+   ```
+
+3. **Install development tools**
+
+   ```bash
+   rustup component add rustfmt clippy
+   cargo install rust-script
+   ```
+
+4. **Install pre-commit hooks** (optional but recommended)
+
+   ```bash
+   pip install pre-commit
+   pre-commit install
+   ```
+
+5. **Build the project**
+
+   ```bash
+   cargo build
+   ```
+
+## Development Workflow
+
+1. **Create a feature branch**
+
+   ```bash
+   git checkout -b feature/my-feature
+   ```
+
+2. **Make your changes**
+
+   - Write code following the project's style guidelines
+   - Add tests for any new functionality
+   - Update documentation as needed
+
+3. **Run quality checks**
+
+   ```bash
+   # Format code
+   cargo fmt
+
+   # Run Clippy lints
+   cargo clippy --all-targets --all-features
+
+   # Check file sizes (requires rust-script)
+   rust-script scripts/check-file-size.rs
+
+   # Run all checks together
+   cargo fmt --check && cargo clippy --all-targets --all-features && rust-script scripts/check-file-size.rs
+   ```
+
+4. **Run tests**
+
+   ```bash
+   # Run all tests
+   cargo test
+
+   # Run tests with verbose output
+   cargo test --verbose
+
+   # Run doc tests
+   cargo test --doc
+
+   # Run a specific test
+   cargo test test_name
+   ```
+
+   CI caps each test-matrix job at 10 minutes. Rust's built-in `cargo test` runner does not provide a portable global per-test timeout, so wrap long-running network, IO, or async tests with explicit test-level deadlines. If a repository adopts `cargo nextest`, configure runner deadlines with options such as `--slow-timeout` and `--leak-timeout`.
+
+5. **Add a changelog fragment**
+
+   For any user-facing changes, create a changelog fragment:
+
+   ```bash
+   # Create a new file in changelog.d/
+   # Format: YYYYMMDD_HHMMSS_description.md
+   touch changelog.d/$(date +%Y%m%d_%H%M%S)_my_change.md
+   ```
+
+   Edit the file to document your changes:
+
+   ```markdown
+   ### Added
+   - Description of new feature
+
+   ### Fixed
+   - Description of bug fix
+   ```
+
+   **Why fragments?** This prevents merge conflicts in CHANGELOG.md when multiple PRs are open simultaneously.
+
+6. **Commit your changes**
+
+   ```bash
+   git add .
+   git commit -m "feat: add new feature"
+   ```
+
+   Pre-commit hooks will automatically run and check your code.
+
+7. **Push and create a Pull Request**
+
+   ```bash
+   git push origin feature/my-feature
+   ```
+
+   Then create a Pull Request on GitHub.
+
+## Code Style Guidelines
+
+This project uses:
+
+- **rustfmt** for code formatting
+- **Clippy** for linting with pedantic and nursery lints enabled
+- **cargo test** for testing
+
+### Code Standards
+
+- Follow Rust idioms and best practices
+- Use documentation comments (`///`) for all public APIs
+- Write tests for all new functionality
+- Keep functions focused and reasonably sized
+- Keep files under 1000 lines
+- Use meaningful variable and function names
+
+### Documentation Format
+
+Use Rust documentation comments:
+
+```rust
+/// Brief description of the function.
+///
+/// Longer description if needed.
+///
+/// # Arguments
+///
+/// * `arg1` - Description of arg1
+/// * `arg2` - Description of arg2
+///
+/// # Returns
+///
+/// Description of return value
+///
+/// # Errors
+///
+/// Description of when errors are returned
+///
+/// # Examples
+///
+/// ```
+/// use my_package::example_function;
+/// let result = example_function(1, 2);
+/// assert_eq!(result, 3);
+/// ```
+pub fn example_function(arg1: i32, arg2: i32) -> i32 {
+    arg1 + arg2
+}
+```
+
+## Testing Guidelines
+
+- Write tests for all new features
+- Maintain or improve test coverage
+- Use descriptive test names
+- Organize tests in modules when appropriate
+- Use `#[cfg(test)]` for test-only code
+
+Example test structure:
+
+```rust
+#[cfg(test)]
+mod tests {
+    use super::*;
+
+    mod my_feature_tests {
+        use super::*;
+
+        #[test]
+        fn test_basic_functionality() {
+            assert_eq!(my_function(), expected_result);
+        }
+
+        #[test]
+        fn test_edge_case() {
+            assert_eq!(my_function(edge_case_input), expected_result);
+        }
+    }
+}
+```
+
+## Pull Request Process
+
+1. Ensure all tests pass locally
+2. Update documentation if needed
+3. Add a changelog fragment (see step 5 in Development Workflow)
+4. Ensure the PR description clearly describes the changes
+5. Link any related issues in the PR description
+6. Wait for CI checks to pass
+7. Address any review feedback
+
+## Changelog Management
+
+This project uses a fragment-based changelog system similar to [Scriv](https://scriv.readthedocs.io/) (Python) and [Changesets](https://github.com/changesets/changesets) (JavaScript).
+
+### Creating a Fragment
+
+```bash
+# Create a new fragment with timestamp
+touch changelog.d/$(date +%Y%m%d_%H%M%S)_description.md
+```
+
+### Fragment Categories
+
+Use these categories in your fragments:
+
+- **Added**: New features
+- **Changed**: Changes to existing functionality
+- **Deprecated**: Features that will be removed in future
+- **Removed**: Features that were removed
+- **Fixed**: Bug fixes
+- **Security**: Security-related changes
+
+### During Release
+
+Fragments are automatically collected into CHANGELOG.md during the release process. The release workflow:
+
+1. Collects all fragments
+2. Updates CHANGELOG.md with the new version entry
+3. Removes processed fragment files
+4. Bumps the version in Cargo.toml
+5. Creates a git tag and GitHub release

+## Release Process
+
+This project uses semantic versioning (MAJOR.MINOR.PATCH):
+
+- **MAJOR**: Breaking changes
+- **MINOR**: New features (backward compatible)
+- **PATCH**: Bug fixes (backward compatible)
+
+Releases are managed through GitHub releases. To trigger a release:
+
+1. Manually trigger the release workflow with a version bump type
+2. Or: Update the version in Cargo.toml and push to main
+

+[![Crates.io](https://img.shields.io/crates/v/example-sum-package-name?label=crates.io&style=flat)](https://crates.io/crates/example-sum-package-name)
+[![Docs.rs](https://docs.rs/example-sum-package-name/badge.svg)](https://docs.rs/example-sum-package-name)
+[![Rust Version](https://img.shields.io/badge/rust-1.70%2B-blue.svg)](https://www.rust-lang.org/)
+[![Codecov](https://codecov.io/gh/link-foundation/rust-ai-driven-development-pipeline-template/branch/main/graph/badge.svg)](https://codecov.io/gh/link-foundation/rust-ai-driven-development-pipeline-template)
+[![License: Unlicense](https://img.shields.io/badge/license-Unlicense-blue.svg)](http://unlicense.org/)
+
+## Features
+
+- **Rust stable support**: Works with Rust stable version
+- **Cross-platform testing**: CI runs on Ubuntu, macOS, and Windows
+- **Comprehensive testing**: Unit tests, integration tests, and doc tests
+- **Code quality**: rustfmt + Clippy with pedantic lints
+- **Pre-commit hooks**: Automated code quality checks before commits
+- **CI/CD pipeline**: GitHub Actions with multi-platform support
+- **Changelog management**: Fragment-based changelog (like Changesets/Scriv)
+- **Code coverage**: Automated coverage reports with cargo-llvm-cov and Codecov
+- **Release automation**: Automatic GitHub releases, crates.io publishing, and optional Docker Hub image publishing
+- **Template-safe defaults**: CI/CD skips publishing when package name is `example-sum-package-name`
+
+## Quick Start
+
+### Using This Template
+
+1. Click "Use this template" on GitHub to create a new repository
+2. Clone your new repository
+3. Update `Cargo.toml`:
+   - Change `name` from `example-sum-package-name` to your package name
+   - Update `description`, `repository`, and `documentation` URLs
+   - Update `[lib]` name and `[[bin]]` name
+4. Update imports in `src/main.rs`, `tests/`, and `examples/`
+5. Build and start developing!
+
+### Development Setup
+
+```bash
+# Clone the repository
+git clone https://github.com/link-foundation/rust-ai-driven-development-pipeline-template.git
+cd rust-ai-driven-development-pipeline-template
+
+# Build the project
+cargo build
+
+# Run tests
+cargo test
+
+# Run the CLI binary
+cargo run -- --a 3 --b 7
+
+# Run an example
+cargo run --example basic_usage
+```
+
+### Running Tests
+
+```bash
+# Run all tests
+cargo test
+
+# Run tests with verbose output
+cargo test --verbose
+
+# Run doc tests
+cargo test --doc
+
+# Run a specific test
+cargo test test_sum_positive_numbers
+
+# Run tests with output
+cargo test -- --nocapture
+```
+
+CI caps each test-matrix job at 10 minutes. `cargo test` does not provide a portable global per-test timeout, so long-running network, IO, or async tests should use explicit test-level timeouts. Repositories that adopt `cargo nextest` can configure runner deadlines with options such as `--slow-timeout` and `--leak-timeout`.
+
+### Code Quality Checks
+
+```bash
+# Format code
+cargo fmt
+
+# Check formatting (CI style)
+cargo fmt --check
+
+# Run Clippy lints
+cargo clippy --all-targets --all-features
+
+# Check file size limits (requires rust-script: cargo install rust-script)
+rust-script scripts/check-file-size.rs
+
+# Run all checks
+cargo fmt --check && cargo clippy --all-targets --all-features && rust-script scripts/check-file-size.rs
+```

+
+## Design Choices
+
+### Example Application
+
+The template includes a simple CLI sum application using [lino-arguments](https://github.com/link-foundation/lino-arguments) (a drop-in replacement for clap that also supports `.lenv` and `.env` files). This demonstrates:
+
+- Library module (`src/sum.rs`) with a pure function
+- CLI binary (`src/main.rs`) using `lino-arguments` for argument parsing
+- Unit tests (`tests/unit/sum.rs`) testing the function directly
+- Integration tests (`tests/integration/sum.rs`) testing the full CLI binary
+
+### Code Quality Tools
+
+- **rustfmt**: Standard Rust code formatter
+- **Clippy**: Rust linter with pedantic and nursery lints enabled
+- **Pre-commit hooks**: Automated checks before each commit
+
+### Testing Strategy
+
+The template supports multiple levels of testing:
+
+- **Unit tests**: In `tests/unit/` directory, testing functions directly
+- **Integration tests**: In `tests/integration/` directory, testing CLI binary
+- **CI/CD tests**: In `tests/unit/ci-cd/` directory, testing CI/CD script logic
+- **Doc tests**: In documentation examples using `///` comments
+- **Examples**: In `examples/` directory (also serve as documentation)
+
+Users can easily delete CI/CD tests in `tests/unit/ci-cd/` if not needed.
+
+### Changelog Management
+
+This template uses a fragment-based changelog system similar to [Changesets](https://github.com/changesets/changesets) and [Scriv](https://scriv.readthedocs.io/).
+
+```bash
+# Create a changelog fragment
+touch changelog.d/$(date +%Y%m%d_%H%M%S)_my_change.md
+
+# Edit the fragment to document your changes
+```
+
+### CI/CD Pipeline
+
+The GitHub Actions workflow provides:
+
+1. **Change detection**: Only runs relevant jobs based on changed files
+2. **Changelog check**: Validates changelog fragments on PRs with code changes
+3. **Version check**: Prevents manual version modification in PRs
+4. **Linting**: rustfmt and Clippy checks
+5. **Test matrix**: 3 OS (Ubuntu, macOS, Windows) with Rust stable
+6. **Code coverage**: cargo-llvm-cov with Codecov upload
+7. **Building**: Release build and package validation
+8. **Auto release**: Automatic releases when changelog fragments are merged to main
+9. **Manual release**: Workflow dispatch with version bump type selection
+10. **Optional Docker Hub publishing**: Pushes `latest` and version tags after the matching crates.io version is visible
+11. **Documentation**: Automatic docs deployment to GitHub Pages after release
+
+### Template-Safe Defaults
+
+The default package name `example-sum-package-name` triggers skip logic in CI/CD scripts:
+- `publish-crate.rs` skips crates.io publishing
+- `create-github-release.rs` skips GitHub release creation
+- Docker Hub publishing stays disabled unless `DOCKERHUB_IMAGE` is configured and a root `Dockerfile` exists
+
+Rename the package in `Cargo.toml` to enable full CI/CD publishing.
+
+## Configuration
+
+### Updating Package Name
+
+After creating a repository from this template:
+
+1. Update `Cargo.toml`:
+   - Change `name` field from `example-sum-package-name`
+   - Update `repository` and `documentation` URLs
+   - Change `[lib]` name and `[[bin]]` name
+
+2. Update imports:
+   - `src/main.rs`
+   - `tests/unit/sum.rs`
+   - `tests/integration/sum.rs`
+   - `examples/basic_usage.rs`
+
+3. Update badges in this `README.md`
+
+### Optional Docker Hub Publishing
+
+Projects that ship a Docker image can publish Docker Hub releases from the same Rust release workflow. Add a root `Dockerfile`, then configure:
+
+| Name | Type | Example | Purpose |
+| ---- | ---- | ------- | ------- |
+| `DOCKERHUB_IMAGE` | Repository variable | `my-dockerhub-user/my-image` | Docker Hub repository to publish |
+| `DOCKERHUB_USERNAME` | Repository variable or secret | `my-dockerhub-user` | Docker Hub login username |
+| `DOCKERHUB_TOKEN` | Repository secret | Docker Hub access token | Docker Hub login token |
+
+When configured, the release workflow publishes both `latest` and the Cargo package version tag, for example `my-dockerhub-user/my-image:0.10.0`. Docker publishing runs only after crates.io reports the matching version as available, and release checks rerun missing Docker Hub or GitHub release artifacts without bumping the version again.
+
+Add a visible Docker Hub badge next to the crates.io badge in repositories that enable image publishing:
+
+```markdown
+[![Docker Hub](https://img.shields.io/docker/v/my-dockerhub-user/my-image?label=docker%20hub)](https://hub.docker.com/r/my-dockerhub-user/my-image)
+```
+
+## Deploying API documentation
+
+The `deploy-docs` job in `.github/workflows/release.yml` publishes `cargo doc --no-deps --all-features` output to GitHub Pages on every push to `main` and on `workflow_dispatch` with `release_mode == 'instant'`. It uses the official `actions/configure-pages` / `actions/upload-pages-artifact` / `actions/deploy-pages` flow, which requires the repository's Pages source to be set to **GitHub Actions**.
+
+Before the first run on `main`, open **Settings → Pages** of the new repository and set **Source = GitHub Actions**. This is a one-time manual step and cannot be configured from a workflow. The `deploy-docs` job will then provision the Pages site on its first run.
+
+If this step is skipped, the first `deploy-docs` run fails on `actions/deploy-pages@v5` with `Error: Get Pages site failed.` / `Error: Failed to create deployment`. Flip the Pages source as described above and re-run the failed job; no workflow changes are required.
+
+## Scripts Reference
+
+All scripts in `scripts/` are Rust scripts that use [rust-script](https://github.com/fornwall/rust-script).
+Install rust-script with: `cargo install rust-script`
+
+| Command                               | Description              |
+| ------------------------------------- | ------------------------ |
+| `cargo test`                          | Run all tests            |
+| `cargo fmt`                           | Format code              |
+| `cargo clippy`                        | Run lints                |
+| `cargo run -- --a 3 --b 7`           | Run CLI (sum 3 + 7)     |
+| `cargo run --example basic_usage`     | Run example              |
+| `rust-script scripts/check-file-size.rs` | Check file size limits |
+| `rust-script scripts/bump-version.rs` | Bump version             |
+
+## Example Usage
+
+```rust
+use example_sum_package_name::sum;
+
+fn main() {
+    let result = sum(2, 3);
+    println!("2 + 3 = {result}");
+}
+```
+
+See `examples/basic_usage.rs` for more examples.

+# Changelog Fragments
+
+This directory contains changelog fragments that will be collected into `CHANGELOG.md` during releases.
+
+## How to Add a Changelog Fragment
+
+When making changes that should be documented in the changelog, create a fragment file:
+
+```bash
+# Create a new fragment with timestamp
+touch changelog.d/$(date +%Y%m%d_%H%M%S)_description.md
+
+# Or manually create a file matching the pattern: YYYYMMDD_HHMMSS_description.md
+```
+
+## Fragment Format
+
+Each fragment should include a **frontmatter section** specifying the version bump type:
+
+```markdown
+---
+bump: patch
+---
+
+### Fixed
+- Description of bug fix
+```
+
+### Bump Types
+
+Use semantic versioning bump types in the frontmatter:
+
+- **`major`**: Breaking changes (incompatible API changes)
+- **`minor`**: New features (backward compatible)
+- **`patch`**: Bug fixes (backward compatible)
+
+### Content Categories
+
+Use these categories in your fragment content:
+
+```markdown
+---
+bump: minor
+---
+
+### Added
+- Description of new feature
+
+### Changed
+- Description of change to existing functionality
+
+### Fixed
+- Description of bug fix
+
+### Removed
+- Description of removed feature
+
+### Deprecated
+- Description of deprecated feature
+
+### Security
+- Description of security fix
+```
+
+## Examples
+
+### Adding a new feature (minor bump)
+
+```markdown
+---
+bump: minor
+---
+
+### Added
+- New async processing mode for batch operations
+```
+
+### Fixing a bug (patch bump)
+
+```markdown
+---
+bump: patch
+---
+
+### Fixed
+- Fixed memory leak in connection pool handling
+```
+
+### Breaking change (major bump)
+
+```markdown
+---
+bump: major
+---
+
+### Changed
+- Renamed `process()` to `process_async()` - this is a breaking change
+
+### Removed
+- Removed deprecated `legacy_mode` option
+```
+
+## Why Fragments?
+
+Using changelog fragments (similar to [Changesets](https://github.com/changesets/changesets) in JavaScript and [Scriv](https://scriv.readthedocs.io/) in Python):
+
+1. **No merge conflicts**: Multiple PRs can add fragments without conflicts
+2. **Per-PR documentation**: Each PR documents its own changes
+3. **Automated version bumping**: Version bump type is specified per-change
+4. **Automated collection**: Fragments are automatically collected during release
+5. **Consistent format**: Template ensures consistent changelog entries
+
+## How It Works
+
+1. **During PR**: Add a fragment file with your changes and bump type
+2. **On merge to main**: The release workflow automatically:
+   - Reads all fragment files and determines the highest bump type
+   - Bumps the version in `Cargo.toml` accordingly
+   - Collects fragments into `CHANGELOG.md`
+   - Creates a git tag and GitHub release
+   - Removes processed fragment files
+
+## Multiple PRs and Bump Priority
+
+When multiple PRs are merged before a release, all pending fragments are processed together. The **highest** bump type wins:
+
+- If any fragment specifies `major`, the release is a major version bump
+- Otherwise, if any specifies `minor`, the release is a minor version bump
+- Otherwise, the release is a patch version bump
+
+This ensures that breaking changes are never missed, even when combined with smaller changes.
+
+## Default Behavior
+
+If a fragment doesn't include a bump type in the frontmatter, it defaults to `patch`.

+# Case Study: Issue #11 - Apply Best Practices from Other Repositories
+
+## Summary
+
+This case study analyzes best practices discovered in several link-foundation repositories and applies them to the `rust-ai-driven-development-pipeline-template`. The goal is to improve the Rust CI/CD pipeline by incorporating lessons learned from real-world issues.
+
+## Referenced Pull Requests

+
+## Best Practices Identified
+
+### 1. Remove Deprecated `set-output` Command (PR #27)
+
+**Problem**: The `::set-output` command was deprecated by GitHub in October 2022 and will eventually be disabled.
+
+**Root Cause**: The `setOutput()` function in version-and-commit.mjs was using both:
+1. The new `GITHUB_OUTPUT` environment file approach (correct)
+2. The deprecated `::set-output` stdout command (causes warnings)
+
+**Solution**: Remove the deprecated `console.log(`::set-output...`)` line and replace with a plain log for visibility.
+
+**References**:
+- [GitHub Changelog: Deprecating save-state and set-output commands](https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/)
+- [GitHub Actions Update on save-state and set-output commands](https://github.blog/changelog/2023-07-24-github-actions-update-on-save-state-and-set-output-commands/)
+
+### 2. Enforce Changelog Fragment Requirement (PR #27, #58)
+
+**Problem**: The changelog fragment check only produced a warning (`::warning::` with `exit 0`) when source code changed without a changelog entry, allowing PRs to pass without proper documentation.
+
+**Root Cause**: Using `exit 0` (success) instead of `exit 1` (failure) in the changelog check.
+
+**Solution**: Change `::warning::` to `::error::` and `exit 0` to `exit 1` to properly fail CI when changelog fragments are missing.
+
+### 3. Fix workflow_dispatch Job Skipping (PR #25)
+
+**Problem**: When triggering the workflow via `workflow_dispatch`, the `detect-changes` job is intentionally skipped. However, jobs with `needs: [detect-changes]` are also skipped due to GitHub Actions' default behavior.
+
+**Root Cause**: When a job dependency is skipped, the dependent job is also skipped - even if its own `if` condition would evaluate to true. This is documented in [GitHub Actions Runner Issue #491](https://github.com/actions/runner/issues/491).
+
+**Solution**: Add `always() && !cancelled()` to job conditions to ensure they run properly when dependencies are skipped, plus explicit checks for `needs.job.result == 'success'`.
+
+**References**:
+- [GitHub Actions Runner Issue #491](https://github.com/actions/runner/issues/491)
+- [GitHub Actions Runner Issue #2205](https://github.com/actions/runner/issues/2205)
+- [GitHub Community Discussion #45058](https://github.com/orgs/community/discussions/45058)
+
+### 4. Add Release Mode Options (PR #25)
+
+**Problem**: The Rust workflow only had one release mode (instant), while the JavaScript workflow had both "instant" and "changelog-pr" modes.
+
+**Solution**: Add `release_mode` workflow input with options:
+- `instant` (default): Direct release that goes through lint/test/build verification
+- `changelog-pr`: Creates a pull request with a changelog fragment for review
+
+### 5. Add crates.io Publishing Support (PR #23)
+
+**Problem**: The Rust workflow only created GitHub releases but didn't publish to crates.io.
+
+**Solution**: Add crates.io publishing step with:
+- `CARGO_TOKEN` secret environment variable for authentication
+- "Publish to Crates.io" step in both `auto-release` and `manual-release` jobs
+- Graceful handling of "already exists" case to avoid failing when version already published
+
+**Note on Trusted Publishing**: crates.io now supports [Trusted Publishing](https://crates.io/docs/trusted-publishing) which uses OIDC for secure, tokenless publishing. This is the recommended approach for new setups but requires `rust-lang/crates-io-auth-action@v1`.
+
+### 6. Update Release Script for Better Flexibility (PR #23)
+
+**Problem**: The `create-github-release.mjs` script had hardcoded tag prefix and didn't support crates.io links.
+
+**Solution**: Add options to the script:
+- `--tag-prefix`: Support different tag formats (e.g., "v" or "rust-v")
+- `--crates-io-url`: Include crates.io link in release notes
+
+## Timeline of Events
+
+### October 11, 2022
+GitHub announces deprecation of `set-output` and `save-state` commands.
+
+### May 31, 2023
+Originally planned disablement date for deprecated commands.
+
+### July 24, 2023
+GitHub postpones removal due to significant usage still observed.
+
+### January 2026
+Issues identified in link-foundation repositories:
+- Issue #26 (lino-env): CI/CD deprecation warnings
+- Issue #24 (lino-env): Manual release not working
+- Issue #22 (lino-env): Add crates.io publishing
+- Issue #57 (start): macOS stdout capture issue (led to discovering changelog check bug)
+
+### January 2026 (PRs Merged)
+- PR #23: crates.io publishing support
+- PR #25: workflow_dispatch fix
+- PR #27: set-output deprecation fix
+- PR #58: macOS stdout capture fix + changelog check enforcement

+
+## Changes Applied to This Template
+
+Based on the analysis, the following changes were applied to this repository:
+
+1. **scripts/version-and-commit.mjs**: Removed deprecated `::set-output` command
+2. **.github/workflows/release.yml**:
+   - Changed changelog check from warning to error (`exit 1`)
+   - Added `always() && !cancelled()` to job conditions
+   - Added `release_mode` input with "instant" and "changelog-pr" options
+   - Added crates.io publishing steps
+   - Added `CARGO_TOKEN` environment variable
+3. **scripts/create-github-release.mjs**: Added `--tag-prefix` and `--crates-io-url` options
+
+## Key Takeaways
+
+1. **Test failure paths**: CI checks should be tested to ensure they actually fail when they should
+2. **Use consistent approaches**: Apply the same patterns across all workflows (JS and Rust)
+3. **Verify CI annotations**: Using `::warning::` instead of `::error::` is a hint that the check might not be enforced
+4. **Understand GitHub Actions behavior**: The `needs` dependency behavior with skipped jobs is subtle and well-documented
+5. **Use `always()` carefully**: Combine with `!cancelled()` and explicit result checks for safety
+6. **Stay current with deprecations**: Regularly check for deprecated GitHub Actions commands

+# Analysis: crates.io Publishing Support
+
+## Issue Summary
+
+- **Source Repository**: [link-foundation/lino-env](https://github.com/link-foundation/lino-env)
+- **Issue**: [#22](https://github.com/link-foundation/lino-env/issues/22)
+- **PR**: [#23](https://github.com/link-foundation/lino-env/pull/23)
+- **Type**: Feature (new functionality)
+
+## Problem Description
+
+The Rust CI/CD workflow only created GitHub releases but didn't publish packages to crates.io, making it incomplete compared to the JavaScript workflow which publishes to npm.
+
+## Solution Overview
+
+### Option 1: Traditional API Token Approach
+
+Uses a manually created crates.io API token stored as a GitHub secret.
+
+**Workflow Addition:**
+```yaml
+env:
+  CARGO_TOKEN: ${{ secrets.CARGO_TOKEN }}
+
+jobs:
+  release:
+    steps:
+      - name: Publish to Crates.io
+        run: |
+          PACKAGE_NAME=$(grep '^name = ' Cargo.toml | head -1 | sed 's/name = "\(.*\)"/\1/')
+          PACKAGE_VERSION=$(grep '^version = ' Cargo.toml | head -1 | sed 's/version = "\(.*\)"/\1/')
+          echo "Package: $PACKAGE_NAME@$PACKAGE_VERSION"
+
+          set +e  # Don't exit on error
+          cargo publish --token ${{ secrets.CARGO_TOKEN }} --allow-dirty 2>&1 | tee publish_output.txt
+          PUBLISH_EXIT_CODE=$?
+          set -e
+
+          if [ $PUBLISH_EXIT_CODE -eq 0 ]; then
+            echo "Successfully published to crates.io"
+          elif grep -q "already uploaded" publish_output.txt || grep -q "already exists" publish_output.txt; then
+            echo "Version already exists on crates.io - this is OK"
+          else
+            echo "Failed to publish"
+            exit 1
+          fi
+```
+
+**Setup:**
+1. Go to [crates.io API tokens](https://crates.io/settings/tokens)
+2. Create a new token with publish permissions
+3. Add it as a repository secret named `CARGO_TOKEN`
+
+### Option 2: Trusted Publishing (Recommended for 2025+)
+
+Uses OIDC for secure, tokenless publishing. This is now the recommended approach.
+
+**Workflow:**
+```yaml
+jobs:
+  release:
+    runs-on: ubuntu-latest
+    permissions:
+      id-token: write  # Required for OIDC token exchange
+    steps:
+      - uses: actions/checkout@v4
+      - uses: rust-lang/crates-io-auth-action@v1
+        id: auth
+      - name: Publish to Crates.io
+        run: cargo publish
+        env:
+          CARGO_REGISTRY_TOKEN: ${{ steps.auth.outputs.token }}
+```
+
+**Setup:**
+1. Go to crates.io package settings
+2. Configure trusted publishing for your GitHub repository
+3. No manual token needed - OIDC handles authentication
+
+**Benefits of Trusted Publishing:**
+- No long-lived secrets to manage
+- Tokens are short-lived (30 minutes)
+- More secure against credential leaks
+- Easier to set up and maintain
+
+## Handling Edge Cases
+
+### Version Already Exists
+
+When a version is already published, `cargo publish` returns an error. Handle gracefully:
+
+```bash
+if grep -q "already uploaded" publish_output.txt || grep -q "already exists" publish_output.txt; then
+  echo "Version already exists on crates.io - this is OK"
+  # Don't fail the workflow
+fi
+```
+
+### Dry Run Testing
+
+Before releasing, test with dry run:
+
+```bash
+cargo publish --dry-run
+```
+
+### Workspace Publishing
+
+For monorepos with multiple crates, consider:
+- Publishing crates in dependency order
+- Using `cargo publish -p crate-name` for specific packages
+- Using tools like `cargo-release` or `cargo-workspaces`
+
+## Release Script Updates
+
+The `create-github-release.mjs` script was updated to support crates.io:
+
+```javascript
+const config = makeConfig({
+  yargs: ({ yargs, getenv }) =>
+    yargs
+      .option('tag-prefix', {
+        type: 'string',
+        default: getenv('TAG_PREFIX', 'v'),
+        describe: 'Tag prefix (e.g., "v" or "rust-v")',
+      })
+      .option('crates-io-url', {
+        type: 'string',
+        default: getenv('CRATES_IO_URL', ''),
+        describe: 'Crates.io package URL to include in release notes',
+      }),
+});
+
+// Add crates.io link to release notes
+if (cratesIoUrl) {
+  releaseNotes = `${cratesIoUrl}\n\n${releaseNotes}`;
+}
+```
+
+**Usage:**
+```bash
+node scripts/create-github-release.mjs \
+  --release-version "1.0.0" \
+  --repository "owner/repo" \
+  --tag-prefix "rust-v" \
+  --crates-io-url "https://crates.io/crates/package-name"
+```
+
+## Complete Workflow Example
+
+```yaml

+# Analysis: GitHub Actions `set-output` Deprecation
+
+## Issue Summary
+
+- **Source Repository**: [link-foundation/lino-env](https://github.com/link-foundation/lino-env)
+- **Issue**: [#26](https://github.com/link-foundation/lino-env/issues/26)
+- **PR**: [#27](https://github.com/link-foundation/lino-env/pull/27)
+- **Type**: Bug (deprecation warning)
+- **Severity**: Low (warnings only, workflow still succeeds)
+- **Risk**: Medium (command may be disabled in future GitHub Actions updates)
+
+## Problem Description
+
+The CI/CD pipeline generates deprecation warnings during the "Instant Release" job:
+
+```
+The `set-output` command is deprecated and will be disabled soon. Please upgrade to using Environment Files.
+For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/
+```
+
+## Root Cause Analysis
+
+### Source Code Location
+
+File: `scripts/version-and-commit.mjs`, `setOutput` function:
+
+```javascript
+function setOutput(key, value) {
+  const outputFile = process.env.GITHUB_OUTPUT;
+  if (outputFile) {
+    appendFileSync(outputFile, `${key}=${value}\n`);
+  }
+  // Also log for visibility
+  console.log(`::set-output name=${key}::${value}`);  // <-- DEPRECATED
+}
+```
+
+### Technical Explanation
+
+The `setOutput` function does two things:
+1. **Correctly** writes to the `GITHUB_OUTPUT` environment file (new approach)
+2. **Also** outputs the deprecated `::set-output` command to stdout (old approach)
+
+While the new approach works correctly, the legacy stdout command is still being printed, causing GitHub Actions to emit deprecation warnings.
+
+### Why Warnings Appear Multiple Times
+
+The `setOutput` function is called in several places:
+- When tag already exists: `setOutput('already_released', 'true')` and `setOutput('new_version', newVersion)`
+- When no changes to commit: `setOutput('version_committed', 'false')` and `setOutput('new_version', newVersion)`
+- After successful push: `setOutput('version_committed', 'true')` and `setOutput('new_version', newVersion)`
+
+## Official Deprecation Timeline
+
+| Date | Event |
+|------|-------|
+| October 11, 2022 | GitHub announces deprecation |
+| May 31, 2023 | Originally planned full disablement |
+| July 24, 2023 | GitHub postpones removal due to significant usage |
+| Present | Warnings shown but commands still functional |
+
+## Migration Guide
+
+### Old Approach (Deprecated)
+
+```bash
+# Shell
+echo "::set-output name=myOutput::myValue"
+```
+
+```javascript
+// JavaScript
+console.log(`::set-output name=${key}::${value}`);
+```
+
+### New Approach (Recommended)
+
+```bash
+# Shell
+echo "myOutput=myValue" >> $GITHUB_OUTPUT
+```
+
+```javascript
+// JavaScript
+import { appendFileSync } from 'fs';
+
+function setOutput(key, value) {
+  const outputFile = process.env.GITHUB_OUTPUT;
+  if (outputFile) {
+    appendFileSync(outputFile, `${key}=${value}\n`);
+    console.log(`Output: ${key}=${value}`);  // Optional: plain log for visibility
+  }
+}
+```
+
+### Handling Multi-line Values
+
+For multi-line outputs, use delimiters:
+
+```bash
+echo "JSON_RESPONSE<<EOF" >> $GITHUB_OUTPUT
+echo "$response_json" >> $GITHUB_OUTPUT
+echo "EOF" >> $GITHUB_OUTPUT
+```
+
+## Fix Applied
+
+The deprecated `console.log` line was removed and replaced with a plain log for visibility:
+
+```javascript
+function setOutput(key, value) {
+  const outputFile = process.env.GITHUB_OUTPUT;
+  if (outputFile) {
+    appendFileSync(outputFile, `${key}=${value}\n`);
+    console.log(`Output: ${key}=${value}`);  // Plain log, not GitHub command
+  }
+}
+```
+
+## Verification
+
+After the fix:
+1. Run a workflow that sets outputs
+2. Check that no deprecation warnings appear in the logs
+3. Verify that subsequent steps can still access the output values

+# Analysis: GitHub Actions workflow_dispatch Job Skipping Issue
+
+## Issue Summary
+
+- **Source Repository**: [link-foundation/lino-env](https://github.com/link-foundation/lino-env)
+- **Issue**: [#24](https://github.com/link-foundation/lino-env/issues/24)
+- **PR**: [#25](https://github.com/link-foundation/lino-env/pull/25)
+- **Type**: Bug (jobs not running)
+- **Severity**: High (release functionality broken)
+
+## Problem Description
+
+When triggering the workflow via `workflow_dispatch` (manual release), the release job was being skipped instead of executing. The workflow ran successfully for automatic releases but failed for manual triggers.
+
+## Root Cause Analysis
+
+### The Core Issue
+
+The `detect-changes` job has this condition:
+```yaml
+detect-changes:
+  if: github.event_name != 'workflow_dispatch'
+```
+
+This means `detect-changes` is intentionally skipped during manual triggers.
+
+However, the `lint` job depends on `detect-changes`:
+```yaml
+lint:
+  needs: [detect-changes]
+  if: |
+    github.event_name == 'push' ||
+    github.event_name == 'workflow_dispatch' ||
+    needs.detect-changes.outputs.rs-changed == 'true' ||
+    ...
+```
+
+### GitHub Actions' Hidden Behavior
+
+When a job dependency is skipped, the dependent job is also skipped by default - **regardless of its own `if` condition**. This happens because:
+
+1. There's an implicit `success()` check applied to all jobs by default
+2. `success()` returns `false` if any dependency was skipped
+3. The job's custom `if` condition is never even evaluated
+
+This behavior is documented in [GitHub Actions Runner Issue #491](https://github.com/actions/runner/issues/491).
+
+### Dependency Chain Breakdown
+
+```
+detect-changes (skipped on workflow_dispatch)
+       |
+       v
+     lint (skipped because dependency was skipped)
+       |
+       v
+     build (skipped because lint.result != 'success')
+       |
+       v
+manual-release (never runs because build was skipped)
+```
+
+### Why Some Jobs Worked
+
+The `test` job had this pattern:
+```yaml
+test:
+  needs: [detect-changes, changelog]
+  if: always() && (github.event_name == 'push' || github.event_name == 'workflow_dispatch' || ...)
+```
+
+The `always()` function forces the `if` condition to be evaluated even when dependencies are skipped.
+
+## Solution
+
+### Fix Job Conditions
+
+Add `always() && !cancelled()` to job conditions:
+
+```yaml
+lint:
+  needs: [detect-changes]
+  if: |
+    always() && !cancelled() && (
+      github.event_name == 'push' ||
+      github.event_name == 'workflow_dispatch' ||
+      needs.detect-changes.outputs.rs-changed == 'true' ||
+      ...
+    )
+```
+
+### Why `!cancelled()`?
+
+Using just `always()` has a side effect: the job will run even if the workflow is cancelled. Adding `!cancelled()` ensures the job respects cancellation requests.
+
+### Check Dependency Results Explicitly
+
+For jobs that depend on other jobs' success:
+
+```yaml
+build:
+  needs: [lint, test]
+  if: |
+    always() && !cancelled() &&
+    needs.lint.result == 'success' &&
+    needs.test.result == 'success'
+```
+
+## Best Practice Patterns
+
+### Pattern 1: Force Evaluation but Require Success
+
+```yaml
+jobs:
+  job-b:
+    needs: [job-a]
+    if: always() && !cancelled() && needs.job-a.result == 'success'
+```
+
+### Pattern 2: Run When Dependency Succeeded OR Skipped
+
+```yaml
+jobs:
+  job-b:
+    needs: [job-a]
+    if: |
+      always() && !cancelled() && (
+        needs.job-a.result == 'success' ||
+        needs.job-a.result == 'skipped'
+      )
+```
+
+### Pattern 3: Run Unless Failure
+
+```yaml
+jobs:
+  job-b:
+    needs: [job-a]
+    if: "!failure()"
+```
+
+This is simpler but less explicit about what conditions are acceptable.
+
+## Full Example
+
+```yaml
+jobs:
+  detect-changes:
+    name: Detect Changes
+    runs-on: ubuntu-latest
+    if: github.event_name != 'workflow_dispatch'
+    outputs:
+      changed: ${{ steps.changes.outputs.changed }}
+    steps:
+      # ... detect changes
+
+  lint:
+    name: Lint
+    runs-on: ubuntu-latest
+    needs: [detect-changes]
+    # Note: always() is required because detect-changes is skipped on workflow_dispatch
+    if: |
+      always() && !cancelled() && (
+        github.event_name == 'workflow_dispatch' ||
+        needs.detect-changes.outputs.changed == 'true'
+      )
+    steps:
+      # ... lint code
+
+  build:
+    name: Build
+    runs-on: ubuntu-latest
+    needs: [lint]
+    if: always() && !cancelled() && needs.lint.result == 'success'
+    steps:
+      # ... build
+
+  release:
+    name: Release
+    needs: [build]
+    if: |
+      always() && !cancelled() &&
+      github.event_name == 'workflow_dispatch' &&
+      needs.build.result == 'success'
+    steps:
+      # ... release
+```

+## 4. Best Practices Summary
+
+### From Official Documentation
+
+1. **Use Environment Files**: Migrate from `::set-output` to `$GITHUB_OUTPUT`
+2. **Understand Job Dependencies**: Jobs in `needs` chain skip if dependency skips
+3. **Use Status Functions**: `always()`, `success()`, `failure()`, `cancelled()`
+4. **Combine Conditions**: `always() && !cancelled() && needs.job.result == 'success'`
+
+### From Community Experience
+
+1. **Test Failure Paths**: Ensure CI checks actually fail when they should
+2. **Be Explicit**: Use explicit result checks rather than relying on defaults
+3. **Document Quirks**: Add comments explaining non-obvious behavior
+4. **Stay Current**: Regularly update actions and check for deprecations
+
+### From Security Best Practices
+
+1. **Use Trusted Publishing**: Prefer OIDC over long-lived API tokens
+2. **Limit Token Scope**: Use least-privilege tokens when manual tokens required
+3. **Use Environments**: Add protection rules for sensitive publishing
+4. **Audit Dependencies**: Review third-party actions before use
+
+## 5. Tools and Resources

+
+## Best Practices Identified
+
+### 1. Yargs Reserved Word Conflict (PR #23)
+
+**Problem**: The `--version` flag is a reserved word in [yargs](https://yargs.js.org/) (v17.2.0+). When using `lino-arguments` (which wraps yargs), defining a custom `--version` option causes yargs to interpret it as its built-in version display command, returning `false` instead of the actual argument value.
+
+**Root Cause**: Yargs reserves `--version` for displaying the application version. When a user defines a custom `version` option without disabling the built-in handling, the argument value is not properly parsed.
+
+**Error Manifestation**:
+```
+Error: Missing required arguments
+Usage: node scripts/create-github-release.mjs --version <version> --repository <repository>
+```
+
+The error is misleading because the arguments ARE being passed, but yargs interprets `--version` specially.
+
+**Solutions** (choose one):
+
+1. **Disable yargs built-in `--version`** (recommended for existing codebases):
+   ```javascript
+   const config = makeConfig({
+     yargs: ({ yargs, getenv }) =>
+       yargs
+         .version(false) // Disable yargs built-in --version handling
+         .option('version', {
+           type: 'string',
+           default: getenv('VERSION', ''),
+           describe: 'Version number',
+         })
+   });
+   ```
+
+2. **Use an alternative option name** (cleaner for new scripts):
+   ```javascript
+   const config = makeConfig({
+     yargs: ({ yargs, getenv }) =>
+       yargs
+         .option('release-version', {  // Avoid reserved word entirely
+           type: 'string',
+           default: getenv('VERSION', ''),
+           describe: 'Version number',
+         })
+   });
+   ```
+
+**Status in this repository**: This template uses the alternative option name approach (`--release-version`) in `create-github-release.mjs`, which already avoids the conflict.
+
+**References**:
+- [yargs/yargs#2064 - Cannot have version as both option and command](https://github.com/yargs/yargs/issues/2064)
+- [yargs version() documentation](https://yargs.js.org/docs/#api-reference-version)
+- [CycloneDX/cdxgen#83 - Warning: "version" is a reserved word](https://github.com/CycloneDX/cdxgen/issues/83)
+
+### 2. Dual Token Support for crates.io (PR #24)
+
+**Problem**: Different CI/CD setups may use different secret names for the crates.io API token:
+- `CARGO_REGISTRY_TOKEN` - Cargo's native environment variable
+- `CARGO_TOKEN` - Alternative name used in some setups
+
+**Root Cause**: Inconsistency in secret naming conventions across repositories and tooling.
+
+**Solution**: Support both token names with fallback logic:
+
+**In workflow files**:
+```yaml
+env:
+  # Support both token names with fallback
+  CARGO_TOKEN: ${{ secrets.CARGO_REGISTRY_TOKEN || secrets.CARGO_TOKEN }}
+```
+
+**In scripts** (publish-crate.mjs):
+```javascript
+const config = makeConfig({
+  yargs: ({ yargs, getenv }) =>
+    yargs.option('token', {
+      type: 'string',
+      default: getenv('CARGO_REGISTRY_TOKEN', '') || getenv('CARGO_TOKEN', ''),
+      describe: 'Crates.io API token',
+    }),
+});
+```
+
+**Warning message** when no token is found:
+```
+::warning::Neither CARGO_REGISTRY_TOKEN nor CARGO_TOKEN is set, attempting publish without explicit token
+```
+
+## Changes Applied
+
+### 1. `.github/workflows/release.yml`
+
+Updated the global environment variable to support both token names:
+
+```yaml
+env:
+  CARGO_TERM_COLOR: always
+  RUSTFLAGS: -Dwarnings
+  # Support both CARGO_REGISTRY_TOKEN (cargo's native env var) and CARGO_TOKEN (for backwards compatibility)
+  CARGO_TOKEN: ${{ secrets.CARGO_REGISTRY_TOKEN || secrets.CARGO_TOKEN }}
+```
+
+### 2. `scripts/publish-crate.mjs`
+
+- Updated documentation to mention both token environment variables
+- Modified `getenv()` call to check both `CARGO_REGISTRY_TOKEN` and `CARGO_TOKEN`
+- Added warning message when neither token is set
+
+## Key Takeaways
+
+1. **Be aware of reserved words**: CLI argument parsing libraries often reserve common flags like `--version`, `--help`, `$0`. Consult the library documentation before choosing option names.
+
+2. **Provide backwards compatibility**: When changing secret/environment variable names, support the old name as a fallback to avoid breaking existing setups.
+
+3. **Use clear warning messages**: When configuration is missing, provide actionable messages that list ALL possible variable names.
+
+4. **Test CI scripts locally**: Running CI scripts locally with the same arguments used in workflows helps identify parsing issues before they cause failures.

+# Case Study: Issue #19 - Supporting Both Single-Language and Multi-Language Repositories in CI/CD Scripts
+
+## Summary
+
+This case study documents the investigation and resolution of a CI/CD pipeline failure that occurred when scripts designed for a multi-language repository structure (`./js/` subfolder) were used in a single-language repository. The root cause was identified as the `command-stream` library's implementation of `cd` as a virtual command that calls `process.chdir()`, permanently changing the Node.js process working directory.
+
+## Background
+
+The `link-foundation` organization maintains multiple repositories with different structures:
+- **Single-language repositories**: Have `package.json` (JS) or `Cargo.toml` (Rust) in the root directory
+- **Multi-language repositories**: Have language-specific code in subfolders (e.g., `./js/`, `./rust/`)
+
+Scripts originally developed for the `link-assistant/agent` multi-language repository were causing failures when paths like `./js/package.json` didn't exist in single-language repositories.
+
+## Original Issue: Issue #113
+
+### CI Failure Details
+
+**CI Run:** [#20885464993](https://github.com/link-assistant/agent/actions/runs/20885464993/job/60008012717)
+**Error Message:**
+```
+Error: ENOENT: no such file or directory, open './js/package.json'
+```
+
+### Timeline of Events
+
+1. **2026-01-10 22:39:00 UTC** - CI run triggered on push to main branch
+2. **2026-01-10 22:39:03 UTC** - Unit tests passed on all platforms (Ubuntu, Windows, macOS)
+3. **2026-01-10 22:40:29 UTC** - Release job started
+4. **2026-01-10 22:40:29 UTC** - Version bump executed successfully via `cd js && npm run changeset:version`
+5. **2026-01-10 22:40:29 UTC** - Script attempted to read `./js/package.json` after the `cd` command
+6. **2026-01-10 22:40:29 UTC** - **FAILURE**: `ENOENT: no such file or directory, open './js/package.json'`
+
+### The Bug: command-stream's Virtual `cd` Command
+
+The root cause was a subtle interaction between the `command-stream` library and Node.js's process working directory:
+
+1. **`command-stream`'s Virtual `cd` Command**: The library implements `cd` as a **virtual command** that calls `process.chdir()` on the Node.js process itself, rather than just affecting the subprocess.
+
+2. **Working Directory Persistence**: When the script executed:
+   ```javascript
+   await $`cd js && npm run changeset:version`;
+   ```
+   The `cd js` command permanently changed the Node.js process's working directory from the repository root to the `js/` subdirectory.
+
+3. **Subsequent File Access Failure**: After the command returned, when the script tried to read `./js/package.json`, it was looking for the file relative to the **new** working directory (`js/`), which would resolve to `js/js/package.json` - a path that doesn't exist.
+
+### Code Flow Illustration
+
+```
+Repository Root (/)
+├── js/
+│   └── package.json    <- This is what we want to read
+└── scripts/
+    └── version-and-commit.mjs
+
+1. Script starts with cwd = /
+2. Script runs: await $`cd js && npm run changeset:version`
+3. command-stream's cd command calls: process.chdir('js')
+4. cwd is now /js/
+5. Script tries to read: readFileSync('./js/package.json')
+6. This resolves to: /js/js/package.json <- DOES NOT EXIST!
+7. Error: ENOENT
+```
+
+### Why This Was Hard to Detect
+
+- The `cd` command in most shell scripts only affects the subprocess, not the parent process
+- Developers familiar with Unix shells would not expect `cd` to affect the Node.js process
+- The error message didn't clearly indicate that the working directory had changed
+- The `command-stream` library documentation doesn't prominently warn about this behavior
+
+## Solution Implemented in PR #114
+
+### 1. Working Directory Preservation and Restoration
+
+The fix involves saving the original working directory and restoring it after any command that uses `cd`:
+
+```javascript
+// Store the original working directory
+const originalCwd = process.cwd();
+
+try {
+  // ... code that uses cd ...
+  await $`cd js && npm run changeset:version`;
+
+  // Restore the original working directory
+  process.chdir(originalCwd);
+
+  // Now file operations work correctly
+  const packageJson = JSON.parse(readFileSync('./js/package.json', 'utf8'));
+} catch (error) {
+  // Handle error
+}
+```
+
+### 2. Auto-Detection of Package Root
+
+New utility modules were created to automatically detect the package root:
+
+**`scripts/js-paths.mjs`** - JavaScript package root detection:
+```javascript
+export function getJsRoot(options = {}) {
+  // Check for single-language repo (package.json in root)
+  if (existsSync('./package.json')) {
+    return '.';
+  }
+  // Check for multi-language repo (package.json in js/ subfolder)
+  if (existsSync('./js/package.json')) {
+    return 'js';
+  }
+  // Error with helpful suggestions
+  throw new Error('Could not find package.json...');
+}
+```
+
+**`scripts/rust-paths.mjs`** - Rust package root detection:
+```javascript
+export function getRustRoot(options = {}) {
+  // Check for single-language repo (Cargo.toml in root)
+  if (existsSync('./Cargo.toml')) {
+    return '.';
+  }
+  // Check for multi-language repo (Cargo.toml in rust/ subfolder)
+  if (existsSync('./rust/Cargo.toml')) {
+    return 'rust';
+  }
+  // Error with helpful suggestions
+  throw new Error('Could not find Cargo.toml...');
+}
+```
+
+### 3. Configuration Options
+
+Scripts now support explicit configuration via:
+- CLI arguments: `--js-root <path>` or `--rust-root <path>`
+- Environment variables: `JS_ROOT` or `RUST_ROOT`
+
+### Usage Examples
+
+```bash
+# Auto-detection (default)
+node scripts/version-and-commit.mjs --mode changeset
+
+# Explicit configuration
+node scripts/version-and-commit.mjs --mode changeset --js-root js
+
+# Via environment variable
+JS_ROOT=js node scripts/version-and-commit.mjs --mode changeset
+```
+
+## Best Practices Identified
+
+### 1. Working Directory Management
+
+When using libraries that may modify process state (like `process.chdir()`):
+- Always save the original state before potentially modifying operations
+- Restore the original state after the operation completes
+- Handle restoration in error paths as well
+
+### 2. Multi-Language Repository Support
+
+Following industry best practices for monorepo CI/CD:
+
+1. **Automatic Detection**: Check for package manifests in standard locations:
+   - Root directory first (single-language repo)
+   - Language-specific subfolders second (multi-language repo)
+
+2. **Explicit Configuration**: Allow overrides via CLI arguments and environment variables
+
+3. **Helpful Error Messages**: When auto-detection fails, provide clear guidance on how to configure manually
+
+4. **Path Abstraction**: Create utility functions that return appropriate paths based on repository structure:
+   - `getPackageJsonPath()` returns `./package.json` or `js/package.json`
+   - `getCargoTomlPath()` returns `./Cargo.toml` or `rust/Cargo.toml`
+
+### 3. CI/CD Pipeline Organization
+
+Based on research from [Buildkite](https://buildkite.com/resources/blog/monorepo-ci-best-practices/), [CircleCI](https://circleci.com/blog/monorepo-dev-practices/), and [Graphite](https://graphite.dev/guides/managing-multiple-languages-in-a-monorepo):
+
+1. **Selective Triggering**: Use path-based filters to only run relevant jobs
+2. **Caching**: Cache language-specific artifacts (node_modules, target/)
+3. **Standardized Commands**: Offer unified scripts that call into the right language-specific tooling
+4. **Modular Organization**: Group projects logically (frontend/, backend/, lib/shared/)
+

+
+## Lessons Learned
+
+1. **Understand Library Internals**: Third-party libraries may have non-obvious behaviors. The `command-stream` library's virtual `cd` command is a powerful feature for maintaining working directory state, but it can cause issues if not handled properly.
+
+2. **Test Edge Cases**: The CI environment differs from local development. File path handling can behave differently depending on the working directory context.
+
+3. **Add Defensive Code**: When using commands that modify process state, always save and restore the original state.
+
+4. **Document Non-Obvious Behaviors**: The fix includes detailed comments explaining why the `process.chdir()` restoration is necessary.
+
+5. **Design for Multiple Repository Structures**: Scripts should be designed to work in both single-language and multi-language repository structures from the start.

If neither exists, throw an error with helpful suggestions\n\n### Configuration Options\n\nScripts support explicit configuration via:\n- CLI arguments: `--js-root <path>` or `--rust-root <path>`\n- Environment variables: `JS_ROOT` or `RUST_ROOT`\n\n### Example Usage\n\n```bash\n# Auto-detection (default)\nnode scripts/version-and-commit.mjs --mode changeset\n\n# Explicit configuration\nnode scripts/version-and-commit.mjs --mode changeset --js-root js\n\n# Via environment variable\nJS_ROOT=js node scripts/version-and-commit.mjs --mode changeset\n```\n\n## Root Cause (Original Issue)\n\nThe original issue (#113) was that `command-stream` library's `cd` command calls `process.chdir()`, which permanently changes the working directory.

++# Case Study: Issue #113 - JavaScript Publish Does Not Work
++
++## Summary
++
++The JavaScript CI/CD pipeline was failing during the release step due to a subtle bug related to how the `command-stream` library handles the `cd` command.
++
++## Timeline of Events
++
++1. **CI Run Triggered**: Push to main branch triggered the JS CI/CD Pipeline (run #20885464993)
++2. **Tests Passed**: Lint, format check, and unit tests all passed successfully
++3. **Release Job Started**: The release job started and began processing changesets
++4. **Version Bump Executed**: The `version-and-commit.mjs` script ran `cd js && npm run changeset:version`
++5. **Failure**: After the version bump completed, the script failed with:
++   ```
++   Error: ENOENT: no such file or directory, open './js/package.json'
++   ```
++
++## Root Cause Analysis
++
++### The Bug
++
++The root cause was a subtle interaction between the `command-stream` library and Node.js's process working directory:
++
++1. **command-stream's Virtual `cd` Command**: The `command-stream` library implements `cd` as a **virtual command** that calls `process.chdir()` on the Node.js process itself, rather than just affecting the subprocess.
++
++2. **Working Directory Persistence**: When the script executed:
++   ```javascript
++   await $`cd js && npm run changeset:version`;
++   ```
++   The `cd js` command permanently changed the Node.js process's working directory from the repository root to the `js/` subdirectory.
++
++3. **Subsequent File Access Failure**: After the command returned, when the script tried to read `./js/package.json`, it was looking for the file relative to the **new** working directory (`js/`), which would resolve to `js/js/package.json` - a path that doesn't exist.
++
++### Code Flow
++
++```
++Repository Root (/)
++├── js/
++│   └── package.json    <- This is what we want to read
++└── scripts/
++    └── version-and-commit.mjs
++
++1. Script starts with cwd = /
++2. Script runs: await $`cd js && npm run changeset:version`
++3. command-stream's cd command calls: process.chdir('js')
++4. cwd is now /js/
++5. Script tries to read: readFileSync('./js/package.json')
++6. This resolves to: /js/js/package.json <- DOES NOT EXIST!
++7. Error: ENOENT
++```
++
++### Why This Was Hard to Detect
++
++- The `cd` command in most shell scripts only affects the subprocess, not the parent process
++- Developers familiar with Unix shells would not expect `cd` to affect the Node.js process
++- The error message didn't clearly indicate that the working directory had changed
++- The `command-stream` library documentation doesn't prominently warn about this behavior
++
++## Solution
++
++The fix involves saving the original working directory and restoring it after any command that uses `cd`:
++
++```javascript
++// Store the original working directory
++const originalCwd = process.cwd();
++
++try {
++  // ... code that uses cd ...
++  await $`cd js && npm run changeset:version`;
++
++  // Restore the original working directory
++  process.chdir(originalCwd);
++
++  // Now file operations work correctly
++  const packageJson = JSON.parse(readFileSync('./js/package.json', 'utf8'));
++} catch (error) {
++  // Handle error
++}
++```
++
++### Files Modified
++
++1. **scripts/version-and-commit.mjs**: Added cwd preservation and restoration after `cd js && npm run changeset:version`
++
++2. **scripts/instant-version-bump.mjs**: Added cwd preservation and restoration after:
++   - `cd js && npm version ${bumpType} --no-git-tag-version`
++   - `cd js && npm install --package-lock-only --legacy-peer-deps`
++
++3. **scripts/publish-to-npm.mjs**: Added cwd preservation and restoration after `cd js && npm run changeset:publish`, including proper handling in the retry loop error path
++
++## Lessons Learned
++
++1. **Understand Library Internals**: Third-party libraries may have non-obvious behaviors. The `command-stream` library's virtual `cd` command is a powerful feature for maintaining working directory state, but it can cause issues if not handled properly.
++
++2. **Test Edge Cases**: The CI environment differs from local development. File path handling can behave differently depending on the working directory context.
++
++3. **Add Defensive Code**: When using commands that modify process state, always save and restore the original state.
++
++4. **Document Non-Obvious Behaviors**: The fix includes detailed comments explaining why the `process.chdir()` restoration is necessary.
++

+# Case Study: Issue #21 - Integrate Best Practices to Prevent Repeating CI/CD Issues
+
+## Summary
+
+This case study analyzes a series of CI/CD failures in the `browser-commander` repository (issues #27, #29, #31, #33) and identifies best practices that should be integrated into the `rust-ai-driven-development-pipeline-template` to prevent similar issues from occurring in derived repositories.
+
+## Timeline of Events
+
+| Date | Issue/PR | Problem | Resolution |
+|------|----------|---------|------------|
+| 2026-01-16 17:09 | Issue #27 | Rust release jobs skipped on workflow_dispatch | Added `always() && !cancelled()` to job conditions |
+| 2026-01-17 09:45 | Issue #29 | False positive version check (git tags vs crates.io) | Changed to check crates.io API instead of git tags |
+| 2026-01-18 01:16 | Issue #31 | Missing `cargo publish` step in workflow | Added `publish-crate.mjs` script and workflow step |
+| 2026-01-18 17:53 | Issue #33 | Secret name mismatch (CARGO_REGISTRY_TOKEN vs CARGO_TOKEN) | Map org secret to standard env var |
+
+### Detailed Sequence
+
+#### Issue #27: Release Jobs Skipped (2026-01-16)
+
+**Root Cause:** When `detect-changes` job is skipped (on `workflow_dispatch`), all dependent jobs are also skipped by default unless they use `always()` in their condition.
+
+**Chain Reaction:**
+1. On `workflow_dispatch`, `detect-changes` is skipped (by design)
+2. Without `always()`, `lint` job is automatically skipped when its dependency is skipped
+3. `build` depends on `lint`, so it's also skipped
+4. `manual-release` depends on `build`, so it's also skipped
+
+**Fix:** Add `always() && !cancelled()` to all dependent job conditions:
+```yaml
+if: |
+  always() && !cancelled() && (
+    github.event_name == 'push' ||
+    github.event_name == 'workflow_dispatch' ||
+    ...
+  )
+```
+
+#### Issue #29: False Positive Version Check (2026-01-17)
+
+**Root Cause:** The workflow checked if a git tag exists to determine if a version was "already released":
+```bash
+if git rev-parse "v$CURRENT_VERSION" >/dev/null 2>&1; then
+    echo "... already released"
+fi
+```
+
+This caused false positives because git tags can exist without the package being published to crates.io.
+
+**Evidence:**
+- `browser-commander` had 10 GitHub releases (v0.1.1 through v0.5.4)
+- But **NONE** of them existed on crates.io
+- The workflow incorrectly marked versions as "already released"
+
+**Fix:** Check crates.io API directly:
+```bash
+CRATES_IO_RESPONSE=$(curl -s "https://crates.io/api/v1/crates/${CRATE_NAME}/${CURRENT_VERSION}")
+if echo "$CRATES_IO_RESPONSE" | grep -q '"version"'; then
+    VERSION_ON_CRATES_IO=true
+fi
+```
+
+#### Issue #31: Missing Cargo Publish Step (2026-01-18 01:16)
+
+**Root Cause:** The workflow correctly detected that versions weren't published to crates.io, but lacked the actual `cargo publish` step.
+
+The workflow only:
+1. Built the release binary (`cargo build --release`)
+2. Created a GitHub release
+
+**Missing step:** Actual `cargo publish` to publish to crates.io.
+
+**Fix:** Add `publish-crate.mjs` script and workflow step:
+```yaml
+- name: Publish to Crates.io
+  if: steps.check.outputs.should_release == 'true'
+  env:
+    CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_TOKEN }}
+  run: node scripts/publish-crate.mjs
+```
+
+#### Issue #33: Secret Name Mismatch (2026-01-18 17:53)
+
+**Root Cause:** The workflow referenced `secrets.CARGO_REGISTRY_TOKEN` but the organization secret was named `CARGO_TOKEN`.
+
+**CI Log Evidence:**
+```
+CARGO_REGISTRY_TOKEN:
+##[warning]Neither CARGO_REGISTRY_TOKEN nor CARGO_TOKEN is set
+error: please provide a non-empty token
+```
+
+**Fix:** Map the organization secret to the expected environment variable:
+```yaml
+env:
+  CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_TOKEN }}
+```
+
+## Root Causes Summary
+
+### 1. GitHub Actions Job Dependency Behavior
+
+**Problem:** When a job is skipped, all dependent jobs are also skipped unless they use `always()`.
+
+**Best Practice:** Always use `always() && !cancelled()` in job conditions when depending on jobs that may be skipped:
+```yaml
+if: always() && !cancelled() && needs.build.result == 'success'
+```
+
+### 2. Version Check Logic
+
+**Problem:** Checking git tags is not sufficient to determine if a version is published.
+
+**Best Practice:** Check the actual package registry (crates.io for Rust, npm for JS, PyPI for Python):
+```javascript
+// Example: Check crates.io API
+const response = await fetch(`https://crates.io/api/v1/crates/${crateName}/${version}`);
+const isPublished = response.ok && (await response.json()).version;
+```
+
+### 3. Missing Publication Steps
+
+**Problem:** Building and creating GitHub releases doesn't mean the package is published to the registry.
+
+**Best Practice:** Always include the publication step:
+- Rust: `cargo publish`
+- JavaScript: `npm publish`
+- Python: `twine upload`
+
+### 4. Environment Variable Naming Conventions
+
+**Problem:** Different naming conventions between organization secrets and what tools expect.
+
+**Best Practice:** Document and standardize secret names. Use mapping when necessary:
+```yaml
+env:
+  CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_REGISTRY_TOKEN || secrets.CARGO_TOKEN }}
+```
+
+## Template vs Browser-Commander Comparison
+
+### Files Present in Template but Missing in Browser-Commander
+
+| Template File | Purpose | Browser-Commander Status |
+|---------------|---------|-------------------------|
+| `scripts/check-release-needed.mjs` | Checks crates.io for version status | Present (in rust/scripts/) |
+| `scripts/git-config.mjs` | Configures git for automated commits | Missing (uses inline script) |
+| `scripts/check-changelog-fragment.mjs` | Validates changelog fragments | Missing (uses inline script) |
+| `scripts/check-version-modification.mjs` | Prevents manual version changes | Missing |
+| `scripts/create-changelog-fragment.mjs` | Creates changelog fragment from workflow | Missing |
+| `.pre-commit-config.yaml` | Pre-commit hooks | Missing |
+| `CONTRIBUTING.md` | Contributing guidelines | Missing |
+| `changelog.d/README.md` | Changelog fragment documentation | Present |
+
+### Workflow Differences
+
+| Feature | Template | Browser-Commander |
+|---------|----------|-------------------|
+| Secret handling | `CARGO_REGISTRY_TOKEN \|\| CARGO_TOKEN` | `CARGO_TOKEN` mapped to `CARGO_REGISTRY_TOKEN` |
+| Version check | External script with crates.io check | Inline script with crates.io check |
+| Git config | External script | Inline commands |
+| Changelog check | External script | Inline script |
+| Version modification check | Present | Missing |
+| Release modes | instant + changelog-pr | Single mode |
+
+## Recommendations for Template Improvements
+
+### 1. Robust Secret Handling (Priority: High)
+
+Add fallback support for multiple secret naming conventions:
+```yaml
+env:
+  CARGO_TOKEN: ${{ secrets.CARGO_REGISTRY_TOKEN || secrets.CARGO_TOKEN }}
+```
+
+This is already implemented in the template.
+
+### 2. Comprehensive Documentation (Priority: High)
+
+Add a "CI/CD Troubleshooting Guide" in the template that covers:
+- Common failure modes (jobs skipped, secret issues, version check failures)
+- How to verify crates.io publication status
+- How to manually trigger releases
+- Secret setup requirements
+
+### 3. Multi-Language Repository Support (Priority: Medium)
+
+The `rust-paths.mjs` module in browser-commander provides excellent support for both:
+- Single-language repos (Cargo.toml at root)
+- Multi-language repos (rust/Cargo.toml)
+
+This should be incorporated into the template.
+
+### 4. Enhanced Error Reporting (Priority: Medium)
+
+The `publish-crate.mjs` script should:
+- Fail explicitly when authentication fails
+- Provide clear error messages about which secret is expected
+- Log the masked token presence for debugging
+
+### 5. Job Result Verification (Priority: High)
+
+All release jobs should verify that upstream jobs succeeded:
+```yaml
+if: |
+  always() && !cancelled() &&
+  needs.lint.result == 'success' &&
+  needs.test.result == 'success' &&
+  needs.build.result == 'success'
+```

+
+## Lessons Learned
+
+1. **Test the complete pipeline end-to-end** - Don't just test individual steps; verify that packages actually appear on the registry.
+
+2. **Document secret naming conventions** - Clearly document which secrets are needed and their exact names.
+
+3. **Use defensive coding in workflows** - Always handle the case where dependencies are skipped using `always() && !cancelled()`.
+
+4. **Check the source of truth** - For package publication, check the actual registry (crates.io), not proxies like git tags.
+
+5. **Provide clear error messages** - When authentication fails, make it obvious which secret is missing or misconfigured.
+
+6. **Keep templates synchronized** - Regularly audit derived repositories against the template to catch missing features or fixes.

+
+## Root Cause Analysis
+
+### Primary Root Cause: Missing `always()` in Job Conditions
+
+The GitHub Actions workflow has a fundamental issue with job dependency evaluation. When a job is skipped, all jobs that depend on it are also skipped by default unless they use `always()` in their condition.
+
+**The Problematic Pattern (current):**
+```yaml
+lint:
+  needs: [detect-changes]
+  if: |
+    github.event_name == 'push' ||
+    github.event_name == 'workflow_dispatch' ||
+    needs.detect-changes.outputs.rs-changed == 'true' ||
+    ...
+```
+
+**The Correct Pattern (from template):**
+```yaml
+lint:
+  needs: [detect-changes]
+  if: |
+    always() && !cancelled() && (
+      github.event_name == 'push' ||
+      github.event_name == 'workflow_dispatch' ||
+      needs.detect-changes.outputs.rs-changed == 'true' ||
+      ...
+    )
+```
+
+### Chain Reaction
+
+1. On `workflow_dispatch`, `detect-changes` is skipped (by design)
+2. Without `always()`, `lint` job is automatically skipped when its dependency is skipped
+3. `build` depends on `lint`, so it's also skipped
+4. `manual-release` depends on `build`, so it's also skipped
+
+### Secondary Root Cause: Inconsistent Condition for Auto Release
+
+The `auto-release` job has the condition:
+```yaml
+if: github.event_name == 'push' && github.ref == 'refs/heads/main'
+```
+
+But it lacks `always() && !cancelled()` prefix and `needs.build.result == 'success'` verification, which can cause issues when upstream jobs use `always()`.
+
+## Solution
+
+### 1. Add `always() && !cancelled()` to All Dependent Jobs
+
+Jobs that depend on `detect-changes` need the pattern:
+```yaml
+if: |
+  always() && !cancelled() && (
+    github.event_name == 'push' ||
+    github.event_name == 'workflow_dispatch' ||
+    ...
+  )
+```
+
+This ensures:
+- `always()` - Job runs even when dependencies are skipped
+- `!cancelled()` - Job doesn't run if workflow was cancelled
+- The actual condition determines if job should run
+
+### 2. Add Result Verification for Release Jobs
+
+Release jobs should verify upstream jobs succeeded:
+```yaml
+auto-release:
+  if: |
+    always() && !cancelled() &&
+    github.event_name == 'push' &&
+    github.ref == 'refs/heads/main' &&
+    needs.build.result == 'success'
+```
+

+# Case Study: Issue #29 - Release Failed Due to False Positive Version Check
+
+## Summary
+
+The CI/CD release workflow incorrectly determined that version 0.4.0 was "already released" when the package `browser-commander` does NOT exist on crates.io at all. This is a **false positive** that prevented the release process from proceeding.
+
+## Timeline of Events
+
+| Timestamp (UTC) | Event |
+|-----------------|-------|
+| 2025-12-28T02:22:51Z | v0.1.1 - First GitHub Release created |
+| 2025-12-28T02:54:13Z | v0.2.0 - GitHub Release created |
+| 2025-12-28T03:48:18Z | v0.2.1 - GitHub Release created |
+| 2025-12-28T04:14:37Z | v0.3.0 - GitHub Release created |
+| 2025-12-28T05:13:22Z | v0.4.0 - GitHub Release created |
+| 2026-01-01T04:19:55Z | v0.5.0 - GitHub Release created |
+| 2026-01-09T14:04:11Z | v0.5.1 - GitHub Release created |
+| 2026-01-10T01:11:29Z | v0.5.2 - GitHub Release created |
+| 2026-01-10T13:40:00Z | v0.5.3 - GitHub Release created |
+| 2026-01-13T20:37:18Z | v0.5.4 - GitHub Release created |
+| 2026-01-17T09:43:31Z | CI Run #21092316062 started |
+| 2026-01-17T09:45:29Z | **FALSE POSITIVE**: "No changelog fragments and v0.4.0 already released" |
+| 2026-01-17T09:45:31Z | Release skipped (Auto Release job ended) |
+
+## Root Cause Analysis
+
+### The Problem
+
+The workflow's version check logic in `.github/workflows/rust.yml` (lines 273-292) uses the following approach:
+
+```yaml
+- name: Check if version already released or no fragments
+  id: check
+  run: |
+    if [ "${{ steps.bump_type.outputs.has_fragments }}" != "true" ]; then
+      CURRENT_VERSION=$(grep -Po '(?<=^version = ")[^"]*' Cargo.toml)
+      if git rev-parse "v$CURRENT_VERSION" >/dev/null 2>&1; then
+        echo "No changelog fragments and v$CURRENT_VERSION already released"
+        echo "should_release=false" >> $GITHUB_OUTPUT
+      # ...
+```
+
+### Why This Is a False Positive
+
+1. **Git Tag ≠ Published Package**: The workflow only checks if a git tag exists (`git rev-parse "v$CURRENT_VERSION"`), NOT whether the package was successfully published to crates.io.
+
+2. **GitHub Release ≠ crates.io Release**: While 10 versions have GitHub releases (v0.1.1 through v0.5.4), **NONE** of them exist on crates.io:
+   ```
+   $ curl -s "https://crates.io/api/v1/crates/browser-commander"
+   {"errors":[{"detail":"crate `browser-commander` does not exist"}]}
+   ```
+
+3. **Missing Publication Step**: The workflow creates GitHub releases but lacks `cargo publish` to actually publish to crates.io.
+
+### Evidence from CI Logs
+
+From `ci-run-21092316062.log` at line 4468:
+```
+Auto Release	UNKNOWN STEP	2026-01-17T09:45:29.1821663Z No changelog fragments and v0.4.0 already released
+```
+
+This message was triggered because:
+- There were no changelog fragments (`has_fragments != "true"`)
+- The git tag `v0.4.0` exists (created on 2025-12-28)
+- But the version was never published to crates.io
+
+## Impact
+
+1. **All 10 releases are GitHub-only**: None of the versions (v0.1.1 through v0.5.4) have been published to crates.io
+2. **Future releases will also fail**: Without changelog fragments, the workflow will always skip release because git tags exist
+3. **Package unavailable**: Users cannot `cargo install browser-commander` or add it as a dependency
+
+## Proposed Solutions
+
+### Solution 1: Add crates.io Check (Recommended)
+
+Check if the version exists on crates.io before assuming it's "already released":
+
+```bash
+# Check if package exists on crates.io
+CRATE_EXISTS=$(curl -s "https://crates.io/api/v1/crates/browser-commander" | grep -c '"errors"' || true)
+VERSION_EXISTS=$(curl -s "https://crates.io/api/v1/crates/browser-commander/$CURRENT_VERSION" | grep -c '"errors"' || true)
+
+if [ "$CRATE_EXISTS" -eq 0 ] && [ "$VERSION_EXISTS" -eq 0 ]; then
+  echo "Version v$CURRENT_VERSION already published to crates.io"
+  echo "should_release=false" >> $GITHUB_OUTPUT
+else
+  echo "Version v$CURRENT_VERSION not on crates.io, proceeding with release"
+  echo "should_release=true" >> $GITHUB_OUTPUT
+fi
+```
+
+### Solution 2: Add cargo publish Step
+
+Add the missing `cargo publish` step to actually publish to crates.io:
+
+```yaml
+- name: Publish to crates.io
+  if: steps.check.outputs.should_release == 'true'
+  env:
+    CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_REGISTRY_TOKEN }}
+  run: cargo publish
+```
+
+### Solution 3: Use katyo/publish-crates Action
+
+Use a well-tested GitHub Action for Rust publishing:
+
+```yaml
+- name: Publish to crates.io
+  uses: katyo/publish-crates@v2
+  with:
+    registry-token: ${{ secrets.CARGO_REGISTRY_TOKEN }}
+```
+
+## Recommended Fix
+
+Implement **all three solutions**:
+
+1. Fix the version check logic to verify crates.io, not just git tags
+2. Add `cargo publish` step to actually publish the package
+3. Consider using the battle-tested `katyo/publish-crates` action

+# Case Study: Issue #31 - Missing Crates.io Publishing
+
+## Summary
+
+The CI/CD pipeline correctly detects that version 0.4.0 is not published to crates.io
+but fails to actually publish because there is no `cargo publish` step in the workflow.
+
+## Timeline/Sequence of Events
+
+### Commit History Leading to Issue
+
+1. Issue #27 ("Rust release jobs skipped") - Identified release jobs weren't running
+2. Issue #29 ("Release failed, because version check got false positive") - Fixed version
+   check to use crates.io API instead of git tags
+3. Issue #31 - Publishing still not working despite correct detection
+
+### CI Run Analysis (Run #21103777967)
+
+**Timestamp**: 2026-01-18T01:16:21Z
+
+**Key Events**:
+1. `Detect Changes` job completed
+2. `Lint and Format Check` passed
+3. `Test` passed on all platforms (ubuntu, macos, windows)
+4. `Build Package` succeeded
+5. `Auto Release` job:
+   - Correctly checked crates.io API
+   - Found `Published on crates.io: false`
+   - Set `should_release=true` and `skip_bump=true`
+   - Built release (`cargo build --release`)
+   - Tried to create GitHub release (failed: tag already exists)
+   - **MISSING**: No `cargo publish` step
+
+## Root Cause Analysis
+
+### Primary Root Cause
+
+The `.github/workflows/rust.yml` workflow is missing the `cargo publish` step.
+The workflow only:
+1. Builds the release binary
+2. Creates a GitHub release
+
+But it never actually publishes to crates.io using `cargo publish`.
+
+### Comparison with Template Repository
+
+The template at `link-foundation/rust-ai-driven-development-pipeline-template`
+includes a critical step that is missing in browser-commander:
+
+```yaml
+- name: Publish to Crates.io
+  if: steps.check.outputs.should_release == 'true'
+  id: publish-crate
+  env:
+    CARGO_TOKEN: ${{ secrets.CARGO_TOKEN }}
+  run: node scripts/publish-crate.mjs
+```
+
+### Missing Files
+
+The browser-commander repository is missing:
+1. `scripts/publish-crate.mjs` - Script to publish to crates.io
+2. `scripts/rust-paths.mjs` - Helper module for multi-language repo support
+
+## Evidence from CI Logs
+
+```
+Crate: browser-commander, Version: 0.4.0, Published on crates.io: false
+No changelog fragments but v0.4.0 not yet published to crates.io
+```
+
+The detection logic works correctly. The workflow then:
+1. Builds the release binary (`cargo build --release`)
+2. Attempts GitHub release creation (HTTP 422 - tag already exists)
+3. **Does not run `cargo publish`**
+
+## Solution
+
+### Required Changes
+
+1. **Add `scripts/publish-crate.mjs`**: Copy from template repository
+2. **Add `scripts/rust-paths.mjs`**: Copy from template repository (required dependency)
+3. **Update `.github/workflows/rust.yml`**: Add the `Publish to Crates.io` step
+
+### Implementation Details
+
+The `publish-crate.mjs` script:
+- Reads package info from Cargo.toml
+- Publishes to crates.io using `cargo publish`
+- Handles "already exists" case gracefully
+- Supports both single-language and multi-language repos
+
+### Workflow Addition
+
+Add after the `Build release` step:
+
+```yaml
+- name: Publish to Crates.io
+  if: steps.check.outputs.should_release == 'true'
+  id: publish-crate
+  env:
+    CARGO_TOKEN: ${{ secrets.CARGO_REGISTRY_TOKEN }}
+  run: node scripts/publish-crate.mjs
+```
+
+## Repository Secret Requirements
+
+The repository needs `CARGO_REGISTRY_TOKEN` (or `CARGO_TOKEN` for backward compatibility)
+to be configured in repository secrets for authentication with crates.io.
+
+## Lessons Learned
+
+1. **Complete workflow validation**: When setting up CI/CD pipelines, verify all steps
+   exist (build, test, package verification, AND publish)
+2. **Template synchronization**: Regularly sync with template repositories to catch
+   missing features
+3. **End-to-end testing**: The version detection was tested, but the actual publish
+   step was not verified to exist

+# Case Study: Issue #33 - Organization Secret CARGO_TOKEN Was Not Applied in Rust Release CI/CD
+
+## Summary
+
+After PR #32 added the `cargo publish` step to the workflow, the release still failed to publish to crates.io. The root cause is a **mismatch between the organization secret name (`CARGO_TOKEN`) and the workflow's secret reference (`secrets.CARGO_REGISTRY_TOKEN`)**.
+
+## Timeline/Sequence of Events
+
+### Commit History Leading to Issue
+
+1. **Issue #27** ("Rust release jobs skipped") - Identified release jobs weren't running
+2. **Issue #29** ("Release failed, because version check got false positive") - Fixed version check to use crates.io API instead of git tags
+3. **Issue #31** ("No actual publishing to crates.io") - Identified missing `cargo publish` step
+4. **PR #32** - Added `publish-crate.mjs` script and workflow step to publish to crates.io
+5. **Issue #33** (this issue) - Despite the fix in PR #32, publishing still fails due to secret name mismatch
+
+### CI Run Analysis (Run #21116038007)
+
+**Timestamp**: 2026-01-18T17:49:49Z
+**Trigger**: Push to main (merge of PR #32)
+**Head SHA**: b7d1eeab81f5df24ad9f3209950f9d312833659d
+
+**Key Events**:
+1. `Detect Changes` job completed successfully
+2. `Lint and Format Check` passed
+3. `Test` passed on all platforms (ubuntu, macos, windows)
+4. `Build Package` succeeded
+5. `Auto Release` job:
+   - Checked crates.io API - Found `Published on crates.io: false`
+   - Set `should_release=true` and `skip_bump=true`
+   - Built release (`cargo build --release`)
+   - **Attempted `Publish to Crates.io`** - **FAILED** with "please provide a non-empty token"
+   - Created GitHub Release (HTTP 422 - tag already exists)
+
+### Critical Log Evidence
+
+From the CI logs at line 4912:
+```
+Auto Release	Publish to Crates.io	2026-01-18T17:53:52.6733565Z   CARGO_REGISTRY_TOKEN:
+```
+
+The `CARGO_REGISTRY_TOKEN` environment variable is **empty** (notice there's nothing after the colon).
+
+From line 4918:
+```
+##[warning]Neither CARGO_REGISTRY_TOKEN nor CARGO_TOKEN is set, attempting publish without explicit token
+```
+
+From lines 4942-4945:
+```
+error: failed to publish browser-commander v0.4.0 to registry at https://crates.io
+
+Caused by:
+  please provide a non-empty token
+```
+
+## Root Cause Analysis
+
+### Primary Root Cause
+
+**The workflow references `secrets.CARGO_REGISTRY_TOKEN` but the organization secret is named `CARGO_TOKEN`.**
+
+In `.github/workflows/rust.yml` (lines 325-331 for auto-release, lines 397-403 for manual-release):
+```yaml
+- name: Publish to Crates.io
+  if: steps.check.outputs.should_release == 'true'
+  id: publish-crate
+  env:
+    CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_REGISTRY_TOKEN }}  # <-- References CARGO_REGISTRY_TOKEN
+  working-directory: .
+  run: node rust/scripts/publish-crate.mjs
+```
+
+The organization has set up a secret named `CARGO_TOKEN`, not `CARGO_REGISTRY_TOKEN`. When the workflow tries to access `secrets.CARGO_REGISTRY_TOKEN`, GitHub returns an empty string because no secret with that exact name exists.
+
+### Contributing Factor: Misleading Script Behavior
+
+The `publish-crate.mjs` script has confusing error handling. Despite the cargo command failing with "please provide a non-empty token", the CI job shows "conclusion":"success". This is because:
+
+1. The script attempts to publish without a token when none is provided
+2. The cargo error is printed to stdout/stderr
+3. But the error propagation from the `command-stream` library may not be handling this specific error case properly
+
+This masking of the failure made the overall CI run show as "success" despite the actual publishing failure.
+
+### Naming Convention Context
+
+According to [Cargo documentation](https://doc.rust-lang.org/cargo/reference/registries.html):
+- **`CARGO_REGISTRY_TOKEN`** is the official environment variable name for crates.io authentication
+- **`CARGO_TOKEN`** is a commonly used alternative name in CI/CD templates
+
+The issue-31 case study recommended using `CARGO_REGISTRY_TOKEN` in the workflow (which is the correct Cargo convention), but the organization secret was created with the name `CARGO_TOKEN`.
+
+## Solution
+
+### Option 1: Update Workflow to Use Existing Secret Name (Recommended)
+
+Change the workflow to reference the existing organization secret `CARGO_TOKEN`:
+
+```yaml
+- name: Publish to Crates.io
+  if: steps.check.outputs.should_release == 'true'
+  id: publish-crate
+  env:
+    CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_TOKEN }}  # Use CARGO_TOKEN org secret
+  working-directory: .
+  run: node rust/scripts/publish-crate.mjs
+```
+
+This maps the organization secret `CARGO_TOKEN` to the environment variable `CARGO_REGISTRY_TOKEN` that Cargo expects.
+
+### Option 2: Rename Organization Secret
+
+Alternatively, rename the organization secret from `CARGO_TOKEN` to `CARGO_REGISTRY_TOKEN` in the GitHub organization settings.
+
+**Note:** Option 1 is recommended as it doesn't require organization admin access and maintains backward compatibility with other repositories that may use `CARGO_TOKEN`.
+
+### Secondary Fix: Improve Error Handling in publish-crate.mjs
+
+The script should fail explicitly when:
+1. No token is provided and the publish fails
+2. The "non-empty token" error is detected
+
+## Files Changed
+
+1. **`.github/workflows/rust.yml`**: Change `${{ secrets.CARGO_REGISTRY_TOKEN }}` to `${{ secrets.CARGO_TOKEN }}` in both `auto-release` and `manual-release` jobs
+
+## Verification Steps
+
+After the fix:
+1. Merge the PR to main
+2. Check the CI run for the `Publish to Crates.io` step
+3. Verify the environment shows `CARGO_REGISTRY_TOKEN: ***` (masked, indicating a value is present)
+4. Verify no "Neither CARGO_REGISTRY_TOKEN nor CARGO_TOKEN is set" warning appears
+5. Verify the package appears on https://crates.io/crates/browser-commander
+
+## Lessons Learned
+
+1. **Secret names must match exactly**: GitHub secrets are case-sensitive and must be referenced by their exact names
+2. **Naming conventions matter**: When following templates, ensure secret names are consistent across the organization
+3. **CI success can be misleading**: A "successful" CI run doesn't guarantee all steps actually succeeded - always check the logs
+4. **Defense in depth**: Error handling in scripts should be explicit about authentication failures

+# Case Study: Issue #25 - version-and-commit.rs Checks Git Tags Instead of Crates.io
+
+## Summary
+
+The `version-and-commit.rs` script used `git rev-parse` to check if a version tag existed, then exited early with `already_released=true` if it did. This created a permanent release pipeline failure loop when GitHub releases created tags without the crate being published to crates.io.
+
+## Timeline of Events
+
+| Date | Event | Detail |
+|------|-------|--------|
+| Prior | browser-commander releases | GitHub releases v0.1.1 through v0.8.0 created tags, but crates.io publishing failed for some |
+| Prior | browser-commander#47 | Pipeline stuck at v0.4.0 on crates.io, GitHub had releases up to v0.8.0 |
+| 2026-01-17 | Issue #29 (browser-commander) | First discovery of git tag vs crates.io divergence |
+| 2026-01-17 | check-release-needed.rs fix | Script was updated to check crates.io API instead of git tags |
+| 2026-04-13 | Issue #25 (this template) | Bug reported: version-and-commit.rs still uses git tags |
+
+## Root Cause Analysis
+
+### The Bug
+
+In `version-and-commit.rs` (lines 152-154), the `check_tag_exists()` function used:
+
+```rust
+fn check_tag_exists(version: &str) -> bool {
+    exec_check("git", &["rev-parse", &format!("v{}", version)])
+}
+```
+
+This checked for git tags as a proxy for "already released", but git tags are not the correct source of truth for Rust package publication.
+
+### Why Git Tags Are Unreliable
+
+1. **GitHub releases create tags** - Creating a GitHub release via the UI or API automatically creates a git tag, even if `cargo publish` was never called
+2. **Failed publishes** - If `cargo publish` fails (auth issues, network errors), the tag may already exist from a prior step
+3. **Manual tag creation** - Developers or automation can create tags without publishing
+4. **Tag prefix mismatches** - Multi-language repos may use different tag prefixes (e.g., `rust_v1.0.0` vs `v1.0.0`)
+
+### The Failure Loop
+
+```
+1. version-and-commit.rs bumps version 0.4.0 → 0.4.1
+2. Checks tag v0.4.1 → EXISTS (from a prior GitHub-only release)
+3. Exits early WITHOUT updating Cargo.toml
+4. cargo publish tries 0.4.0 → "already exists" on crates.io
+5. Pipeline is permanently stuck — every run hits the same tag check
+```
+
+### Why check-release-needed.rs Was Already Correct
+
+The `check-release-needed.rs` script (added during issue #21 investigation) already used the correct approach — querying the crates.io API:
+
+```rust
+fn check_version_on_crates_io(crate_name: &str, version: &str) -> bool {
+    let url = format!("https://crates.io/api/v1/crates/{}/{}", crate_name, version);
+    // HTTP 200 = published, 404 = not published
+}
+```
+
+The inconsistency arose because `version-and-commit.rs` was not updated at the same time.
+
+## Solution
+
+### Changes Made
+
+1. **Replaced `check_tag_exists()` with `check_version_on_crates_io()`** in `version-and-commit.rs`
+   - Added `ureq`, `serde`, and `serde_json` dependencies
+   - Added `get_crate_name()` helper to read crate name from Cargo.toml
+   - Queries `https://crates.io/api/v1/crates/{crate_name}/{version}` API endpoint
+   - Returns `true` only if crates.io confirms the version exists
+
+2. **Added `--tag-prefix` support** to `version-and-commit.rs`
+   - Configurable tag prefix (default `"v"`) for multi-language repos
+   - Aligns with `create-github-release.rs` which already supports `--tag-prefix`
+
+3. **Added test script** (`experiments/test-crates-io-check.rs`)
+   - Validates the crates.io API check against known published and unpublished versions
+
+### Design Decisions
+
+- **On error, assume not published** - If the crates.io API is unreachable, the script assumes the version is not yet published. This is safer than incorrectly skipping a release.
+- **Consistent with check-release-needed.rs** - Both scripts now use the same approach, reducing confusion and maintenance burden.
+
+## Lessons Learned
+
+1. **Use the authoritative source of truth** - For Rust packages, crates.io is the source of truth, not git tags
+2. **Keep related scripts consistent** - When fixing a pattern in one script, audit all scripts for the same anti-pattern
+3. **Test with real API calls** - The experiment script validates the fix against actual crates.io data
+4. **Multi-language repos need tag prefixes** - Hard-coded `v` prefix breaks in monorepos with multiple languages

+# Case Study: Issue #29 - Unsupported Look-Ahead Regex in create-github-release.rs
+
+## Summary
+
+The `scripts/create-github-release.rs` script used a regex pattern containing a positive look-ahead assertion `(?=...)`, which is not supported by Rust's `regex` crate. This caused a panic during GitHub release creation, preventing releases from completing even though crates.io publishing succeeded.
+
+## Timeline of Events
+
+| Date | Event | Detail |
+|------|-------|--------|
+| Prior | Template scripts converted to Rust | All CI/CD scripts were translated from JavaScript (.mjs) to Rust (.rs) using rust-script (Issue #25 era) |
+| Prior | Regex pattern introduced | The `get_changelog_for_version()` function was written with `(?=\n## \[|$)` look-ahead |
+| 2026-04-13 | mem-rs v0.2.0 release attempt | `linksplatform/mem-rs` release published to crates.io but GitHub Release creation panicked |
+| 2026-04-13 | linksplatform/mem-rs#34 | Bug reported after investigating the failed release |
+| 2026-04-13 | Issue #29 filed | Bug ported back to this template repository for fix |
+
+## Root Cause Analysis
+
+### The Bug
+
+In `scripts/create-github-release.rs` (line 80), the changelog parsing function used:
+
+```rust
+let pattern = format!(r"(?s)## \[{}\].*?\n(.*?)(?=\n## \[|$)", escaped_version);
+let re = Regex::new(&pattern).unwrap();
+```
+
+The `(?=\n## \[|$)` portion is a **positive look-ahead assertion**, which tells the regex engine: "match only if followed by `\n## [` or end-of-string, but don't consume the match."
+
+### Why Rust's `regex` Crate Doesn't Support Look-Ahead
+
+Rust's `regex` crate uses a **finite automaton (FA) engine** that guarantees **linear-time matching** — O(n) in the length of the input, regardless of the pattern. This is a deliberate design choice for safety and performance:
+
+1. **Look-ahead requires backtracking** — Look-ahead assertions need the engine to "peek ahead" without consuming input, which requires backtracking or a separate pass
+2. **Backtracking engines can be exponential** — PCRE-style engines with look-ahead can exhibit catastrophic backtracking (O(2^n)) on adversarial inputs
+3. **Rust prioritizes safety** — The `regex` crate trades feature completeness for guaranteed performance bounds
+
+The `regex` crate documents this explicitly: "look-around, including look-ahead and look-behind, is not supported."
+
+### The Failure Mode
+
+```
+thread 'main' panicked at scripts/create-github-release.rs:48:35:
+called `Result::unwrap()` on an `Err` value: Syntax(
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+regex parse error:
+    (?s)## \[0\.2\.0\].*?\n(.*?)(?=\n## \[|$)
+                                 ^^^
+error: look-around, including look-ahead and look-behind, is not supported
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+)
+```
+
+The `.unwrap()` on the `Regex::new()` result converts the compilation error into a panic, crashing the script.
+
+### How the Bug Was Introduced
+
+When CI/CD scripts were translated from JavaScript to Rust, the regex pattern was likely carried over from a JavaScript implementation where `RegExp` supports look-ahead natively (JavaScript's regex engine is PCRE-based). The pattern worked correctly in the `.mjs` version but is invalid in Rust.
+
+## Solution
+
+### Fix Applied
+
+Replaced the single look-ahead regex with a **two-step approach**:
+
+```rust
+// Step 1: Find the version header
+let header_pattern = format!(r"(?m)^## \[{}\]", escaped_version);
+let header_re = Regex::new(&header_pattern).unwrap();
+
+if let Some(m) = header_re.find(&content) {
+    // Step 2: Skip past the header line
+    let after_header = &content[m.end()..];
+    let body_start = after_header.find('\n').map_or(after_header.len(), |i| i + 1);
+    let body = &after_header[body_start..];
+
+    // Step 3: Find the next section boundary
+    let next_section_re = Regex::new(r"(?m)^## \[").unwrap();
+    let section_body = if let Some(next) = next_section_re.find(body) {
+        &body[..next.start()]
+    } else {
+        body  // Last section — take everything remaining
+    };
+
+    let trimmed = section_body.trim();
+    if trimmed.is_empty() {
+        format!("Release v{}", version)
+    } else {
+        trimmed.to_string()
+    }
+}
+```
+
+### Why This Approach
+
+1. **No look-ahead needed** — Instead of asserting "followed by `## [`", we find the boundary explicitly using a second regex and use string slicing
+2. **Handles edge cases** — Works for the last section (no next `## [` header), empty sections, and versions with regex-special characters (dots are escaped)
+3. **Uses only `regex` crate features** — All patterns are FA-compatible with guaranteed linear-time matching
+4. **Equivalent semantics** — Produces identical output to the original pattern's intent
+
+### Verification
+
+A test script (`experiments/test-changelog-parsing.rs`) validates:
+- Extracting a version section bounded by another section
+- Extracting the last version section (no trailing boundary)
+- Non-existent version returns default message
+- Version strings with dots are properly regex-escaped
+- Empty version sections return the default fallback
+
+## Impact
+
+- **Affected repositories** — Any repository using this template's `create-github-release.rs` script
+- **Known incident** — `linksplatform/mem-rs` v0.2.0 release: crates.io published successfully, but GitHub Release creation failed
+- **Severity** — The release was partially complete: the package was available on crates.io but the GitHub Release with notes and badges was missing
+
+## Lessons Learned
+
+1. **Test regex patterns at compile time** — When porting regex patterns between languages, verify compatibility with the target engine. Rust's `regex` crate has documented limitations.
+2. **Avoid `.unwrap()` on regex compilation from dynamic patterns** — Consider using `expect()` with a descriptive message or handling the error gracefully to provide actionable diagnostics.
+3. **Language migration requires testing** — When translating scripts from JavaScript to Rust, patterns, libraries, and runtime behavior differ. Each translation should include tests that exercise the ported logic.
+4. **Two-step parsing is often cleaner** — Using string slicing with simple regex matches is more readable and debuggable than complex single-regex patterns with assertions.

+# Case Study: Issue #32 — Publish Steps Override Workflow-Level CARGO_TOKEN Fallback
+
+## Summary
+
+The CI/CD pipeline's publish steps used a step-level `env` block that overrode the workflow-level `CARGO_TOKEN` fallback chain, breaking repositories that only configure `CARGO_REGISTRY_TOKEN` as a secret. Additionally, the `version-and-commit.rs` script lacked push retry logic, causing failures in multi-workflow repositories with concurrent release jobs.
+
+## Timeline of Events
+
+1. **Origin**: The issue was first observed in [link-assistant/web-capture#46](https://github.com/link-assistant/web-capture/issues/46), where `CARGO_REGISTRY_TOKEN` was not set in the publish step, causing the publish to skip silently.
+
+2. **Discovery**: Investigation revealed that the workflow-level `env` block correctly defined a fallback chain (`${{ secrets.CARGO_REGISTRY_TOKEN || secrets.CARGO_TOKEN }}`), but the per-step `env` blocks in both `auto-release` and `manual-release` jobs overrode this with only `${{ secrets.CARGO_TOKEN }}`, which would be empty if only `CARGO_REGISTRY_TOKEN` was configured.
+
+3. **Related issue #31**: In [link-assistant/agent](https://github.com/link-assistant/agent), the Rust auto-release job failed with `non-fast-forward` errors when a JS release job pushed to `main` first. The `version-and-commit.rs` script did a single `git push` with no retry or rebase logic.
+
+4. **Scope expansion**: Comparison with reference repos (browser-commander, lino-arguments, trees-rs, Numbers) revealed additional gaps in mono-repo path support across several scripts.
+
+## Root Cause Analysis
+
+### Problem 1: CARGO_TOKEN Fallback (Issue #32)
+
+**Root cause**: GitHub Actions step-level `env` blocks override workflow-level `env` for the same variable name. The publish steps set:
+
+```yaml
+env:
+  CARGO_TOKEN: ${{ secrets.CARGO_TOKEN }}
+```
+
+This overrides the workflow-level `CARGO_TOKEN: ${{ secrets.CARGO_REGISTRY_TOKEN || secrets.CARGO_TOKEN }}`, making `CARGO_TOKEN` empty when only `CARGO_REGISTRY_TOKEN` is configured as a repository secret.
+
+**Mitigating factor**: The `publish-crate.rs` script checks both `CARGO_REGISTRY_TOKEN` and `CARGO_TOKEN` environment variables (in that order), so publishing still worked because `CARGO_REGISTRY_TOKEN` was inherited from the workflow-level env. However, this was fragile and misleading.
+
+**Fix**: Set both `CARGO_REGISTRY_TOKEN` (with fallback) and `CARGO_TOKEN` at both workflow and step levels:
+
+```yaml
+env:
+  CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_REGISTRY_TOKEN || secrets.CARGO_TOKEN }}
+  CARGO_TOKEN: ${{ secrets.CARGO_TOKEN }}
+```
+
+### Problem 2: Non-Fast-Forward Push (Issue #31)
+
+**Root cause**: The `version-and-commit.rs` script performed a single `git push` without first rebasing on the remote branch. In multi-workflow repositories where multiple release jobs can push to `main` concurrently, the first push succeeds but subsequent pushes fail with `non-fast-forward` errors.
+
+**Fix**: Added pre-commit `git fetch` + `rebase` and post-commit push retry (3 attempts) with `git pull --rebase` between failures.
+
+### Problem 3: Inconsistent Mono-Repo Support
+
+**Root cause**: Several scripts (`check-changelog-fragment.rs`, `check-version-modification.rs`, `create-changelog-fragment.rs`) hardcoded paths like `Cargo.toml`, `changelog.d/`, `src/`, `tests/` without considering the `rust/` subdirectory prefix used in multi-language repositories.
+
+**Fix**: Added `get_rust_root()` detection (checks `RUST_ROOT` env var, then auto-detects `./Cargo.toml` vs `./rust/Cargo.toml`) to all affected scripts.
+
+## Requirements from Issue

+|---|---|---|
+| 1 | Fix CARGO_TOKEN fallback in publish steps | Done |
+| 2 | Support CARGO_REGISTRY_TOKEN-only configurations | Done |

+
+## Affected Repositories
+
+The same CARGO_TOKEN fallback issue exists in:
+- `link-foundation/browser-commander` (`.github/workflows/rust.yml`)
+- `link-foundation/lino-arguments` (`.github/workflows/rust.yml`)

+# Case Study: Issue #34 — detect-code-changes Uses Full PR Diff Instead of Per-Commit Diff
+
+## Summary
+
+The `detect-code-changes.rs` script compared the full PR diff (base SHA to head SHA) instead of evaluating each commit individually. This caused a commit that only modified non-code files (e.g., `.gitkeep`, `README.md`) to trigger all CI jobs if any earlier commit in the same PR touched code files.
+
+## Timeline of Events
+
+1. **Origin**: The issue was first observed in [link-assistant/web-capture PR #49](https://github.com/link-assistant/web-capture/pull/49), where commit `0e9b6e8c` only modified `.gitkeep` but triggered all 8 CI jobs because the PR as a whole contained code changes.
+
+2. **Root cause identified**: GitHub Actions checks out a **synthetic merge commit** for `pull_request` events:
+   - `HEAD` = synthetic merge commit
+   - `HEAD^` = base branch (first parent)
+   - `HEAD^2` = actual PR head commit (second parent)
+
+   Using `git diff HEAD^ HEAD` or `git diff base_sha head_sha` gives the **full PR diff**, not the per-commit diff. This is the same fundamental problem as GitHub Actions' `paths:` filters.
+
+3. **Fix developed and verified**: The fix was first implemented and CI-verified in [link-assistant/web-capture PR #51](https://github.com/link-assistant/web-capture/pull/51) using a JavaScript implementation (`detect-code-changes.mjs`).
+
+4. **Cross-repo filing**: The same issue was filed on both template repos:
+   - Rust template: [link-foundation/rust-ai-driven-development-pipeline-template#34](https://github.com/link-foundation/rust-ai-driven-development-pipeline-template/issues/34)
+   - JS template: [link-foundation/js-ai-driven-development-pipeline-template#31](https://github.com/link-foundation/js-ai-driven-development-pipeline-template/issues/31)
+
+## Root Cause Analysis
+
+### Problem: Full PR Diff Instead of Per-Commit Diff
+
+**Root cause**: The `get_changed_files()` function in `detect-code-changes.rs` used `GITHUB_BASE_SHA` and `GITHUB_HEAD_SHA` environment variables to compute `git diff base_sha head_sha`, which returns all files changed across the entire PR — not just the latest commit.
+
+**Before (broken)**:
+```rust
+if event_name == "pull_request" {
+    let base_sha = env::var("GITHUB_BASE_SHA").ok();
+    let head_sha = env::var("GITHUB_HEAD_SHA").ok();
+    if let (Some(base), Some(head)) = (base_sha, head_sha) {
+        exec_silent("git", &["fetch", "origin", &base]);
+        let output = exec("git", &["diff", "--name-only", &base, &head]);
+        // This returns ALL files changed in the PR, not just the latest commit
+    }
+}
+```
+
+**Why `HEAD^..HEAD` also doesn't work for PRs**: GitHub Actions creates a synthetic merge commit for `pull_request` events. `HEAD^` is the base branch (first parent), so `git diff HEAD^ HEAD` also gives the full PR diff — the exact same problem.
+
+**After (fixed)**:
+```rust
+fn is_merge_commit() -> bool {
+    let output = exec("git", &["cat-file", "-p", "HEAD"]);
+    output.lines().filter(|line| line.starts_with("parent ")).count() > 1
+}
+
+fn get_changed_files() -> Vec<String> {
+    if is_merge_commit() {
+        // HEAD^2 = actual PR head, HEAD^2^ = its parent
+        // This gives the per-commit diff of the latest push
+        let output = exec("git", &["diff", "--name-only", "HEAD^2^", "HEAD^2"]);
+        // ...
+    }
+    // For push events: HEAD^ to HEAD (regular per-commit diff)
+}
+```
+
+**Key insight**: `HEAD^2` is the actual PR head commit (second parent of the merge commit). `HEAD^2^` is its parent. So `git diff HEAD^2^ HEAD^2` gives exactly the per-commit diff of the latest push to the PR.
+
+### Workflow Change
+
+The `GITHUB_BASE_SHA` and `GITHUB_HEAD_SHA` environment variables were removed from the workflow's detect-changes step since they are no longer needed — the script now uses git's commit graph directly.
+
+## Requirements from Issue
+
+| # | Requirement | Status |
+|---|---|---|
+| 1 | Use per-commit diff instead of full PR diff for change detection | Done |
+| 2 | Handle GitHub Actions synthetic merge commit correctly | Done |
+| 3 | Follow best practices from web-capture PR #51 | Done |
+| 4 | Create case study with root cause analysis | Done |
+| 5 | Create experiment scripts for testing | Done |
+
+## Possible Solutions Considered
+
+| Solution | Pros | Cons | Chosen? |
+|---|---|---|---|
+| Merge commit detection (`HEAD^2^..HEAD^2`) | Accurate per-commit diff; works without env vars; proven in web-capture CI | Requires understanding of git merge commit structure | Yes |
+| Use `GITHUB_BASE_SHA`/`GITHUB_HEAD_SHA` with commit limiting | Uses official GitHub API values | Still gives full PR diff; doesn't solve the core problem | No |
+| GitHub Actions `paths:` filters | Built-in, no script needed | Evaluates full PR diff; same fundamental problem | No |
+
+## CI Verification
+
+The fix was verified in CI run [#24394764654](https://github.com/link-foundation/rust-ai-driven-development-pipeline-template/actions/runs/24394764654). The last commit (removing `.gitkeep`) correctly triggered only the per-commit diff:
+
+```
+Merge commit detected (pull_request event)
+Comparing HEAD^2^ to HEAD^2 (per-commit diff of PR head)
+Changed files:
+  .gitkeep
+rs-changed=false
+toml-changed=false
+any-code-changed=false
+```
+
+As a result, Lint, Code Coverage, and Changelog Fragment Check were all correctly **skipped** — they would have been triggered under the old full-PR-diff behavior because earlier commits in the PR modified `.rs` and `.yml` files.
+
+## Additional Context: GitHub Actions Merge Commit Behavior
+
+GitHub Actions creates two special refs for every pull request:
+- `refs/pull/NUMBER/head` — the HEAD of the PR branch
+- `refs/pull/NUMBER/merge` — a synthetic merge commit previewing the merge into the target branch
+
+When using the `pull_request` trigger, `@actions/checkout` checks out `refs/pull/NUMBER/merge` (the synthetic merge commit). This means:
+- `HEAD` is the merge commit (has 2 parents)
+- `HEAD^` (first parent) is the base branch tip
+- `HEAD^2` (second parent) is the actual PR head commit
+
+This is documented in the [GitHub community discussion on base.sha behavior](https://github.com/orgs/community/discussions/59677) and the [Frontside deep dive into pull_request](https://frontside.com/blog/2020-05-26-github-actions-pull_request/). The [actions/checkout issue #426](https://github.com/actions/checkout/issues/426) also discusses the distinction between checking out the merge commit vs the HEAD commit.

+# Issue 38 Case Study: Decouple Documentation Deployment From Package Release Publication
+
+## Summary
+
+Issue [#38](https://github.com/link-foundation/rust-ai-driven-development-pipeline-template/issues/38) reported that Rust API documentation deployment was coupled to package release publication in `.github/workflows/release.yml`. A failed package or GitHub release caused `deploy-docs` to be skipped, even when the package build had already succeeded and documentation could still be generated.
+
+The fix changes `deploy-docs` to depend on `build`, gates it on `needs.build.result == 'success'`, and preserves the existing trigger intent: deploy docs on `main` pushes and manual `workflow_dispatch` runs with `release_mode == 'instant'`. The fix also cleans up release-script warning failures that were blocking the observed release path under `RUSTFLAGS=-Dwarnings`.
+
+## Collected Data
+
+Raw GitHub and template comparison data is stored in this directory:
+
+- `raw-data/issue-38.json` and `raw-data/issue-38-comments.json`: issue details and the latest issue comments.
+- `raw-data/pr-39.json`, `raw-data/pr-39-conversation-comments.json`, `raw-data/pr-39-review-comments.json`, and `raw-data/pr-39-reviews.json`: prepared PR data.
+- `raw-data/main-run-24465255225.json` and `raw-data/main-run-24465255225.log.gz`: Rust template `main` release run that reproduced the issue.
+- `raw-data/downstream-meta-before-run-24983875003.json` and `.log.gz`: downstream `meta-ontology` run before the same fix.
+- `raw-data/downstream-meta-after-run-24985948212.json` and `.log.gz`: downstream `meta-ontology` run after the same fix.
+- `raw-data/pr-run-25212295127.json` and `.log.gz`: initial PR branch CI run.
+- `raw-data/js-template-issue-search.json` and `raw-data/rust-template-issue-search.json`: search results for matching template issues.
+- `template-data/rust-template-release-before.yml` and `template-data/rust-template-release-after.yml`: before/after workflow snapshots.
+- `template-data/js-template-release.yml`, `template-data/js-template-links.yml`, and template tree files: JavaScript template comparison inputs.
+
+The downloaded CI logs have more than 1500 lines, so the analysis references narrow uncompressed line ranges instead of embedding full logs.
+
+## Timeline
+
+- 2026-04-15 16:12:07 UTC: Rust template `main` release run `24465255225` started at commit `353d893ba0a26ecec6fb1ba1716b6a9ad27e1fef`.
+- 2026-04-15 16:13:54 to 16:14:09 UTC: `Build Package` succeeded in run `24465255225`.
+- 2026-04-15 16:14:11 to 16:15:21 UTC: `Auto Release` failed in run `24465255225`.
+- 2026-04-15 16:15:22 UTC: `Deploy Rust Documentation` was skipped in run `24465255225`, even though `Build Package` succeeded.
+- 2026-04-27 08:11:01 UTC: downstream `meta-ontology` run `24983875003` reproduced the same pattern: build succeeded, auto release failed, docs deploy skipped.
+- 2026-04-27 08:59:30 UTC: downstream `meta-ontology` run `24985948212`, after applying the same workflow dependency fix, showed `Auto Release` failing while `Deploy Rust Documentation` succeeded.
+- 2026-05-01 11:11:28 UTC: the Rust template issue was updated with a broader request to compare Rust and JavaScript templates, preserve evidence, and document the analysis.
+- 2026-05-01 11:12:08 UTC: PR [#39](https://github.com/link-foundation/rust-ai-driven-development-pipeline-template/pull/39) was created from `issue-38-325a287cfa55`.
+
+## Requirements
+
+The issue and follow-up comment required:
+
+- Decouple documentation deployment from package release publication.
+- Keep docs deployment limited to successful builds.
+- Preserve the intended release triggers: `main` push and manual instant workflow dispatch.
+- Investigate historical CI logs and related downstream work.
+- Compare the Rust and JavaScript pipeline templates.
+- File or identify related template issues if the same bug exists elsewhere.
+- Add a reproducing automated test before the fix.
+- Store research and data under `docs/case-studies/issue-38`.
+
+## Root Cause
+
+The workflow-level cause was:
+
+```yaml
+deploy-docs:
+  needs: [auto-release, manual-release]
+```
+
+Because `deploy-docs` depended on release publication jobs, it was downstream of both release success and release failure. The old `if` condition only allowed docs deployment when either release job succeeded. In the observed `main` run, `auto-release` failed and `manual-release` was skipped, so `deploy-docs` was skipped.
+
+GitHub Actions documentation confirms the dependency behavior: jobs declared in `needs` wait for those jobs, and failed or skipped dependencies skip downstream jobs unless a job-level condition explicitly changes that behavior. The `needs` context exposes each direct dependency result as `success`, `failure`, `cancelled`, or `skipped`. GitHub also recommends `!cancelled()` for jobs that should continue after non-critical failures without running after cancellation.
+
+The release-path failure was separate but relevant. In run `24465255225`, the `Auto Release` job failed while running `rust-script scripts/check-release-needed.rs` under `RUSTFLAGS=-Dwarnings`. The downloaded log shows:
+
+- `raw-data/main-run-24465255225.log.gz`, uncompressed lines 4798-4809: `check-release-needed.rs` was invoked with `HAS_FRAGMENTS=true` and `RUSTFLAGS=-Dwarnings`.
+- Lines 4810-4817: `get_arg` in `scripts/check-release-needed.rs` failed as dead code.
+- Lines 4819-4854: shared helper functions in `scripts/rust-paths.rs` also failed as dead code when the file was imported as a module.
+- Lines 4855-4857: the script compile failed and the job exited with code 1.
+
+The downstream `meta-ontology` before-fix run `24983875003` showed the same warnings-as-errors pattern in uncompressed lines 5699-5758.
+
+## Solution
+
+The workflow fix makes documentation depend only on the successful build artifact boundary:
+
+```yaml
+deploy-docs:
+  needs: [build]
+  if: |
+    !cancelled() &&
+    needs.build.result == 'success' && (
+      (github.event_name == 'push' && github.ref == 'refs/heads/main') ||
+      (github.event_name == 'workflow_dispatch' && github.event.inputs.release_mode == 'instant')
+    )
+```
+
+This keeps documentation independent from package publication while still requiring a known-good build. It also avoids using `always()` for the docs job, so cancellation still stops the workflow.
+
+The script cleanup removes the unused `get_arg` helper from `check-release-needed.rs` and marks `rust-paths.rs` as an importable script utility with `#![allow(dead_code)]`. That resolves the concrete `RUSTFLAGS=-Dwarnings` failure observed in CI without weakening the rest of the repository lint settings.
+
+## Regression Test
+
+`tests/unit/ci-cd/workflow_release.rs` reproduces the workflow bug structurally. It extracts the `deploy-docs` job block from `.github/workflows/release.yml` and asserts that:
+
+- `deploy-docs` depends on `build`.
+- the condition checks `needs.build.result == 'success'`.
+- the condition still limits push deployments to `refs/heads/main`.
+- the job no longer depends on `auto-release` or `manual-release` results.
+
+Before the workflow change, this test failed on `deploy_docs.contains("needs: [build]")`. After the fix, it passes.
+
+## Template Comparison
+
+Rust template:
+
+- Before fix: `template-data/rust-template-release-before.yml` used `cancel-in-progress: true` and `deploy-docs.needs: [auto-release, manual-release]`.
+- After fix: `template-data/rust-template-release-after.yml` uses `cancel-in-progress: ${{ github.ref == 'refs/heads/main' }}` and `deploy-docs.needs: [build]`.
+- Search results in `raw-data/rust-template-issue-search.json` found the existing tracked issue: #38. No additional Rust template issue is needed.
+
+JavaScript template:
+
+- `template-data/js-template-release.yml` has no documentation deployment job and no GitHub Pages publication job, so the exact docs-release coupling bug does not exist there.
+- The JavaScript template already uses `cancel-in-progress: ${{ github.ref == 'refs/heads/main' }}`, which avoids cancelling in-progress PR checks while keeping stale `main` release runs under control.
+- The JavaScript template has a `validate-docs` job for documentation-only validation, but that is a validation concern rather than a deployment concern.
+- Search results in `raw-data/js-template-issue-search.json` found no matching issue to file or update.
+
+## Online Research
+
+Official GitHub documentation used for the workflow reasoning:
+
+- [Workflow syntax: `jobs.<job_id>.needs`](https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-syntax#jobsjob_idneeds)
+- [Contexts reference: `needs` context](https://docs.github.com/en/actions/reference/workflows-and-actions/contexts#needs-context)
+- [Expressions: status check functions](https://docs.github.com/en/actions/reference/workflows-and-actions/expressions#status-check-functions)
+- [GitHub Pages custom workflows](https://docs.github.com/en/pages/getting-started-with-github-pages/using-custom-workflows-with-github-pages)
+- [actions/deploy-pages README](https://github.com/actions/deploy-pages)
+
+GitHub Pages documentation and `actions/deploy-pages` both describe the build-then-deploy shape for Pages deployments. This PR does not migrate from `peaceiris/actions-gh-pages@v4` to `actions/deploy-pages`, because that would be a broader repository settings and permissions change. The narrow fix is to correct this workflow's dependency graph.
+
+## Verification
+
+Local checks run on 2026-05-01:
+
+- `cargo test --test unit ci_cd::workflow_release::documentation_deploy_is_independent_from_release_publication`
+- `RUSTFLAGS=-Dwarnings HAS_FRAGMENTS=true rust-script scripts/check-release-needed.rs`
+- `cargo fmt --all -- --check`
+- `cargo test --all-features --verbose`
+- `cargo test --doc --verbose`
+- `cargo clippy --all-targets --all-features`
+- `rust-script scripts/check-file-size.rs`
+- `cargo build --release --verbose`
+- `cargo package --list --allow-dirty`
+
+The downstream after-fix run `24985948212` provides live workflow evidence that the dependency shape works: `Build Package` succeeded, `Auto Release` failed, and `Deploy Rust Documentation` still succeeded. The deploy job built docs at uncompressed lines 5801-5802 and completed `peaceiris/actions-gh-pages@v4` successfully at lines 6074-6082.

This couples GitHub Pages documentation deployment to package/GitHub release publication.\n\n## Reproducible Example\n\n1. Use the current `release.yml` from `link-foundation/rust-ai-driven-development-pipeline-template`.\n2. Run the workflow on `main` with a package build that succeeds.\n3. Make the release publication path fail, for example by missing/invalid crates.io credentials, a crates.io publish failure, or a release script failure.\n4. Observe that `Deploy Rust Documentation` is skipped because it needs the failed release job.\n\nThe same pattern reproduced in `link-foundation/meta-ontology`:\n\n- `Build Package` succeeded.\n- `Auto Release` failed.\n- `Deploy Rust Documentation` was skipped.\n\nSee downstream issue: https://github.com/link-foundation/meta-ontology/issues/3\n\n## Workaround\n\nAfter a release failure, manually rerun a documentation deployment job or manually build and publish `target/doc` to GitHub Pages.\n\n## Suggested Fix\n\nMake documentation deployment depend on the successful validation/build job instead of release publication jobs. For example:\n\n```yaml\ndeploy-docs:\n  needs: [build]\n  if: |\n    !cancelled() &&\n    needs.build.result == 'success' && (\n      (github.event_name == 'push' && github.ref == 'refs/heads/main') ||\n      (github.event_name == 'workflow_dispatch' && github.event.inputs.release_mode == 'instant')\n    )\n```\n\nThis keeps the website release tied to a successful build while allowing it to proceed when package publication or GitHub release creation fails.\n","comments":[{"id":"IC_kwDOQvQFhs8AAAABA9FquQ","author":{"login":"konard"},"authorAssociation":"MEMBER","body":"Use all the best practices from CI/CD templates (check full file tree to compare for all GitHub workflow and CI/CD scripts file), if the same issue is found in template report issue also in templates:\n- https://github.com/link-foundation/js-ai-driven-development-pipeline-template\n- https://github.com/link-foundation/rust-ai-driven-development-pipeline-template\n\nWe should compare all files, so we don't have more CI/CD errors in the future and reuse all the best practices from these templates.\n\nWe need to download all logs and data related about the issue to this repository, make sure we compile that data to `./docs/case-studies/issue-{id}` folder, and use it to do deep case study analysis (also make sure to search online for additional facts and data), in which we will reconstruct timeline/sequence of events, list of each and all requirements from the issue, find root causes of the each problem, and propose possible solutions and solution plans for each requirement (we should also check known existing components/libraries, that solve similar problem or can help in solutions).\n\nIf there is not enough data to find actual root cause, add debug output and verbose mode if not present, that will allow us to find root cause on next iteration.\n\nIf issue related to any other repository/project, where we can report issues on GitHub, please do so.

+# Case Study: Issue #52 - Track Parity for browser-commander Preview-Regeneration Pattern
+
+## Summary
+
+Issue [#52](https://github.com/link-foundation/rust-ai-driven-development-pipeline-template/issues/52) is a **tracking placeholder**, not a code change. The primary host for the pattern is [`link-foundation/js-ai-driven-development-pipeline-template#62`](https://github.com/link-foundation/js-ai-driven-development-pipeline-template/issues/62). The original real-world implementation lives in [`konard/vk-bot-desktop#52`](https://github.com/konard/vk-bot-desktop/pull/52), which closed [`konard/vk-bot-desktop#51`](https://github.com/konard/vk-bot-desktop/issues/51).
+
+The pattern automates preview-image regeneration (README screenshots, the Pages site, and the `og:image`) at release time using [`browser-commander`](https://www.npmjs.com/package/browser-commander) and Playwright, then commits the drift back to `main` with `[skip ci]`. This Rust template currently ships no example-app surface that would render those screenshots, so the pattern cannot be applied here today. This case study captures the recipe so that the **next** PR that adds an example-app surface (a renderer, a Pages site with screenshots, or anything visual) can adopt the recipe verbatim instead of re-discovering it.
+
+## Why this is a tracking issue, not an implementation
+
+The upstream survey ([`docs/case-studies/issue-51/data/templates/survey.md`](https://github.com/konard/vk-bot-desktop/blob/issue-51-60ec0489f01f/docs/case-studies/issue-51/data/templates/survey.md) in `vk-bot-desktop`) confirmed that none of the four `link-foundation` AI-driven-development-pipeline-template repos ship browser automation or screenshot tooling. For this Rust template specifically:
+
+- There is no example-app frontend surface in `src/`, `examples/`, or `docs/`.
+- The Pages site deployed by `deploy-docs` is `cargo doc` output, which is not screenshot-driven.
+- The `og:image` referenced from `README.md` is a static image, not a generated artifact.
+- The `scripts/` directory is Rust-script-based (`rust-script`), with no Node.js toolchain wired in.
+
+Because there is nothing to screenshot, adding a `preview-regen` job today would either run against an empty surface or hard-code fake fixtures. Either choice would drift from the upstream recipe rather than mirror it. The right move is to **register the pattern** so the next contributor adding visual surface picks it up without redoing the audit.
+
+## The pattern in one paragraph
+
+A release-time GitHub Actions job boots the example app's built site behind a static HTTP server (no Electron, no devserver), drives it through a locale × theme matrix using `browser.newContext({ locale })` + `commander.emulateMedia({ colorScheme })` + a `localStorage` theme key, captures fresh screenshots via `commander.page.screenshot()` (because `browser-commander@0.8` exposes the raw Playwright page; the package has no native screenshot method as of 0.10.1), then uses `git status --porcelain` drift detection and `git commit -m "... [skip ci]"` to push the drift back to `main`. `PREVIEW_VERBOSE=1` dumps DOM probes (`data-theme`, `lang`, `h1` contents) so CI failures are diagnosable from logs alone.
+
+## Reference implementation
+
+The canonical implementation to mirror (do not re-derive):
+
+- Script: [`scripts/update-preview-images.mjs`](https://github.com/konard/vk-bot-desktop/blob/issue-51-60ec0489f01f/scripts/update-preview-images.mjs) in `vk-bot-desktop`.
+- Workflow job: the [`preview-regen` job](https://github.com/konard/vk-bot-desktop/blob/issue-51-60ec0489f01f/.github/workflows/js.yml#L657) in `.github/workflows/js.yml`.
+- Triggers: push to `main`, release tag pushes, and `workflow_dispatch`.
+
+For this Rust template the screenshot script does **not** need to be Rust-native. The `scripts/` directory can shell out to a Node-only script identical to the JavaScript one. Keeping the script in Node sidesteps re-implementing Playwright bindings in Rust and matches the rest of the `link-foundation` ecosystem.
+
+## Activation checklist (apply when an example-app surface lands)
+
+When a future PR adds a visual surface to this template, follow this checklist in order. Each item maps directly to a building block in the upstream recipe.
+
+1. **Identify the screenshot target.** Decide whether the screenshot source is the example app's built site (preferred), a static Pages site, or a headless renderer. The site must be servable over plain HTTP.
+2. **Add a Node-only screenshot script.** Copy [`scripts/update-preview-images.mjs`](https://github.com/konard/vk-bot-desktop/blob/issue-51-60ec0489f01f/scripts/update-preview-images.mjs) verbatim, adjust the input/output paths, and keep it in `scripts/` next to the Rust scripts. Do not port it to Rust.
+3. **Pin `browser-commander` and Playwright.** Match the pin already used by sibling repos. As of the reference implementation, `browser-commander` is on `0.8` and exposes the raw Playwright page via `commander.page` — so screenshots go through `commander.page.screenshot()`, not a wrapper.
+4. **Add a `preview-regen` job to `.github/workflows/release.yml`** (or a new `example-app.yml` if/when the Rust template grows one). The job runs on push to `main`, on release tag pushes, and on `workflow_dispatch`.
+5. **Drive the locale × theme matrix from the workflow.** Use `browser.newContext({ locale })` for locale and `commander.emulateMedia({ colorScheme })` + `localStorage` for theme. Do not toggle theme through a UI segmented control — emulation is deterministic, UI toggling is not.
+6. **Serve, do not devserver.** Spin up a static HTTP server over the built site (`npx serve` or equivalent) inside the job. Avoid devservers and avoid Electron, which the upstream recipe explicitly sidesteps.
+7. **Drift detection + push-back.** Use `git status --porcelain` to detect changed bytes. When changes exist, `git add`, `git commit -m "chore(preview): regenerate preview images [skip ci]"`, and `git push`. The `[skip ci]` token is what keeps the loop from re-triggering itself.
+8. **Diagnostic verbosity.** Wire a `PREVIEW_VERBOSE=1` env flag through the script that dumps `data-theme`, `lang`, and visible `h1` contents at capture time. Without this, CI failures in headless mode are nearly undebuggable from logs alone.
+9. **Concurrency guard.** Add `concurrency: { group: preview-regen-${{ github.ref }}, cancel-in-progress: false }` to the job so back-to-back pushes don't race each other on the `[skip ci]` commit.
+10. **Backfill a changelog fragment.** Use `bump: minor` because the new job is a feature, not a fix. Reference this case study from the fragment so the connection to issue #52 survives the changelog collection step.
+
+## Why each building block matters
+
+- **Static HTTP server, not Electron or devserver.** The upstream `vk-bot-desktop` recipe is intentionally renderer-only at screenshot time. This keeps the job runnable on a vanilla `ubuntu-latest` runner without GPU, display server, or Electron build artifacts.
+- **`browser.newContext({ locale })` for locale.** Driving locale through the browser context is deterministic, parallelizable across contexts, and does not depend on the app exposing a locale switcher. Switching locale via in-UI controls forces serial state and adds a class of "wrong locale was captured" bugs.
+- **`emulateMedia({ colorScheme })` + `localStorage` for theme.** `emulateMedia` covers system-driven theme detection. `localStorage` covers apps that persist explicit user choice. Both together cover the matrix of apps that use either signal or both.
+- **`commander.page.screenshot()`, not a wrapper.** `browser-commander@0.8` (and through `0.10.1`) does not expose a screenshot method on the commander itself — only on the raw Playwright page. Calling `commander.page.screenshot()` is the documented escape hatch; future versions may add a wrapper, but this one is stable today.
+- **`[skip ci]` on the drift commit.** Without `[skip ci]`, the drift commit re-triggers the workflow, which captures the same (now stable) screenshots, finds no drift, and exits. That is non-fatal but wastes a runner. With `[skip ci]`, the loop is self-terminating.
+- **`PREVIEW_VERBOSE=1` DOM probes.** Headless Playwright failures often surface as "screenshot looks wrong" with no log signal. Dumping `data-theme`, `lang`, and `h1` contents at capture time turns those failures into single-glance diagnosis: "wrong theme was applied", "locale didn't load", "page didn't render".
+
+## Parity with sibling templates
+
+The same tracking issue exists for the C# template ([`csharp-ai-driven-development-pipeline-template#17`](https://github.com/link-foundation/csharp-ai-driven-development-pipeline-template/issues/17)) and the Python template ([`python-ai-driven-development-pipeline-template#9`](https://github.com/link-foundation/python-ai-driven-development-pipeline-template/issues/9)). All four templates (JS, Rust, C#, Python) are expected to converge on the same `preview-regen` job shape, so when one of them ships the first real implementation the other three should mirror it.
+
+When this template adopts the pattern, also:
+
+1. Comment on the upstream JS issue ([#62](https://github.com/link-foundation/js-ai-driven-development-pipeline-template/issues/62)) linking the implementation PR here.
+2. Cross-link the sibling C# and Python tracking issues.
+3. Update this case study from "tracking" to "implemented", adding before/after CI run links and a link to the implementation PR.
+
+## Collected Data
+
+Raw GitHub data is stored in `raw-data/`:
+
+- `issue-52.json` — the tracking issue at the time of registration.
+- `issue-52-comments.json` — issue comments at the time of registration (empty until the implementation PR lands).
+- `js-issue-62.json` — the primary upstream tracking issue on the JS template.
+- `vk-bot-desktop-issue-51.json` — the original problem statement that prompted the recipe.
+- `vk-bot-desktop-pr-52.json` — the reference implementation PR.
+
+## Status
+
+**Tracking — no implementation in this template yet.** The pattern is registered here and ready to be applied as soon as an example-app surface lands. The pull request that registers this case study makes documentation-only changes and does not modify any workflow, script, or runtime code.

Commits any drift back to `main` with `[skip ci]`.\n- **`fix(renderer): hoist flushSave/applyAndSave`** in `electron/renderer/App.jsx`: pre-existing temporal-dead-zone bug that prevented the renderer from rendering at all when the bundle was loaded outside Electron. Blocking for the screenshot pipeline; in scope for #51.\n- **`docs/case-studies/issue-51/`**: full inventory, root-cause analysis, link-foundation template parity survey, and acceptance criteria.\n\n## What the new script does\n\n| Surface                      | File regenerated                                | Strategy                                                                                                                                                                                                  |\n| ---------------------------- | ----------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| Site landing tile (en/light) | `site/assets/app-preview-en-light.png`          | Renderer bundle served statically; `browser.newContext({ locale: 'en-US' })` + `localStorage['vk-bot-desktop:theme']='light'` + `emulateMedia({ colorScheme: 'light' })`; capture via `commander.page.screenshot()`. |\n| Same, en/dark, ru/light, ru/dark | `site/assets/app-preview-{en,ru}-{light,dark}.png` | Same recipe, looped over `LOCALES × THEMES`.                                                                                                                                                              |\n| Share-image fallback         | `site/assets/app-preview.png`                   | Copy of `app-preview-en-light.png`.                                                                                                                                                                       |\n| README landing               | `docs/screenshots/issue-26-pages-en-dark.png`   | Same renderer-based capture path with a `1440 × 950` viewport to match the original aspect ratio.                                                                                                         |\n\nVerbose mode is wired (`PREVIEW_VERBOSE=1`) so a future regression is diagnosable from CI logs alone (per **R7** in the case study).\n\n## What's intentionally **not** automated\n\n`docs/screenshots/issue-31-macos-*.png` are macOS Gatekeeper system dialogs — they reflect Apple's OS UI, not ours, so they're explicitly out of scope. Documented in `docs/case-studies/issue-51/README.md` § 4.\n\n## Template parity (R5/R8)\n\nI surveyed all four `link-foundation/*-ai-driven-development-pipeline-template` repos. **None** ship browser automation or screenshot tooling. Detailed per-template findings live in `docs/case-studies/issue-51/data/templates/survey.md`.

run lint` → clean\n- [x] `npm run format:check` → clean\n- [x] `npm run check:duplication` → clean\n- [x] `npm test` → 270/270 passing (including the updated `tests/ci-timeouts.test.js` that now enforces `preview-regen: 20`)\n- [x] `npm run preview:update --skip-build` regenerates all six target PNGs against the post-fix renderer bundle, and the resulting images render correctly in both themes and locales\n- [ ] After merge: confirm `preview-regen` job is green on first push to `main`, and that a no-op run (no drift) exits cleanly\n\n## Regenerated preview

+# CI/CD Troubleshooting Guide
+
+This guide covers common CI/CD issues and their solutions for Rust projects using this template.

+
+---
+
+## Release Jobs Skipped
+
+### Symptom
+Release jobs (auto-release or manual-release) are skipped even though you expected them to run.
+
+### Common Causes
+
+#### 1. Upstream job was skipped
+When a job like `detect-changes` is skipped (e.g., on `workflow_dispatch`), all dependent jobs are also skipped by default.
+
+**Solution:** Ensure dependent jobs use `always() && !cancelled()` in their conditions:
+```yaml
+if: |
+  always() && !cancelled() && (
+    github.event_name == 'push' ||
+    github.event_name == 'workflow_dispatch' ||
+    needs.detect-changes.outputs.rs-changed == 'true'
+  )
+```
+
+#### 2. Build or test failed
+Release jobs depend on `build` which depends on `lint` and `test`. If any of these fail, release jobs won't run.
+
+**Solution:** Check the logs for lint, test, and build jobs. Fix any failures before releasing.
+
+#### 3. Wrong trigger condition
+The job condition may not match your trigger event.
+
+**Solution:** Verify the job's `if` condition matches your trigger:
+- `github.event_name == 'push'` for automatic releases on merge
+- `github.event_name == 'workflow_dispatch'` for manual triggers

+
+---
+
+## Version Already Released (False Positive)
+
+### Symptom
+The release workflow says "version already released" but the package is not actually on crates.io.
+
+### Root Cause
+The workflow was checking git tags instead of crates.io. Git tags can exist without the package being published (e.g., from previous GitHub-only releases).
+
+### Solution
+This template now checks crates.io directly using the API:
+```javascript
+const response = await fetch(
+  `https://crates.io/api/v1/crates/${crateName}/${version}`
+);
+const isPublished = response.ok && (await response.json()).version;
+```
+
+### Verification
+Check if your package exists on crates.io:
+```bash
+curl -s "https://crates.io/api/v1/crates/YOUR_CRATE_NAME" | jq
+```
+
+### Reference
+- [browser-commander Issue #29](https://github.com/link-foundation/browser-commander/issues/29)
+
+---
+
+## Crates.io Publishing Fails
+
+### Symptom
+The "Publish to Crates.io" step fails with an error.
+
+### Common Errors
+
+#### "please provide a non-empty token"
+**Cause:** The `CARGO_REGISTRY_TOKEN` environment variable is empty or not set.
+
+**Solution:**
+1. Ensure you have a secret configured (either `CARGO_REGISTRY_TOKEN` or `CARGO_TOKEN`)
+2. Map the secret correctly in your workflow:
+```yaml
+- name: Publish to Crates.io
+  env:
+    CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_TOKEN }}
+  run: node scripts/publish-crate.mjs
+```
+
+#### "already uploaded" or "already exists"
+**Cause:** This version was already published to crates.io.
+
+**Note:** This is handled gracefully by the script and is not a failure.
+
+#### "unauthorized" or authentication errors
+**Cause:** Invalid or expired token.
+
+**Solution:**
+1. Generate a new token at https://crates.io/settings/tokens
+2. Update the secret in your repository or organization settings
+

+- [Cargo Publishing Documentation](https://doc.rust-lang.org/cargo/reference/publishing.html)
+
+---
+
+## Docker Hub Publishing Fails
+
+### Symptom
+The crates.io publish succeeds, but the release workflow fails before or during Docker Hub publishing.
+
+### Required Configuration
+
+Docker Hub publishing is optional. It runs only when all of these are true:
+
+- A root `Dockerfile` exists
+- Repository variable `DOCKERHUB_IMAGE` is set to `namespace/repository`
+- `DOCKERHUB_USERNAME` is set as a repository variable or secret
+- Repository secret `DOCKERHUB_TOKEN` is set
+
+### Common Errors
+
+#### "Docker Hub publishing requires DOCKERHUB_USERNAME and DOCKERHUB_TOKEN"
+**Cause:** `DOCKERHUB_IMAGE` and `Dockerfile` enabled Docker publishing, but credentials are incomplete.
+
+**Solution:** Set `DOCKERHUB_USERNAME` and create a Docker Hub access token stored as `DOCKERHUB_TOKEN`.
+
+#### Docker tag is missing after crates.io already published
+**Cause:** A previous release run published the crate, then failed before Docker Hub or GitHub Release completed.
+
+**Solution:** Re-run the release workflow after fixing the Docker Hub configuration. The release check treats the version as incomplete and recreates missing artifacts without bumping the Cargo version again.
+
+### Verification
+Check whether a Docker Hub tag exists:
+
+```bash
+curl -fsSL "https://hub.docker.com/v2/repositories/NAMESPACE/REPOSITORY/tags/VERSION"
+```
+
+### Reference
+- [Docker GitHub Actions guide](https://docs.docker.com/build/ci/github-actions/)
+
+---
+
+## Secret Configuration Issues
+
+### Required Secrets
+
+| Secret Name | Purpose | Where to Get |
+|------------|---------|--------------|
+| `CARGO_REGISTRY_TOKEN` or `CARGO_TOKEN` | Publish to crates.io | https://crates.io/settings/tokens |
+| `DOCKERHUB_TOKEN` | Publish to Docker Hub when `DOCKERHUB_IMAGE` is configured | https://app.docker.com/settings/personal-access-tokens |
+| `GITHUB_TOKEN` | Create GitHub releases | Automatic (provided by GitHub) |
+
+### Organization vs Repository Secrets
+
+If using organization secrets with different names, map them in your workflow:
+```yaml
+env:
+  # Map organization secret to the expected variable name
+  CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_TOKEN }}
+```
+
+### Checking Secret Values
+
+Secrets are masked in logs, but you can verify they're set:
+```yaml
+- name: Debug secrets
+  run: |
+    if [ -n "$CARGO_REGISTRY_TOKEN" ]; then
+      echo "CARGO_REGISTRY_TOKEN is set (value masked)"
+    else
+      echo "WARNING: CARGO_REGISTRY_TOKEN is NOT set"
+    fi
+  env:
+    CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_TOKEN }}
+```
+

+
+---
+
+## Multi-Language Repository Issues
+
+### Symptom
+Scripts fail to find `Cargo.toml` or run in the wrong directory.
+
+### Solution
+This template auto-detects the repository structure:
+- **Single-language:** `Cargo.toml` in repository root
+- **Multi-language:** `Cargo.toml` in `rust/` subfolder
+
+If auto-detection fails, you can explicitly configure the Rust root:
+```bash
+# Via environment variable
+RUST_ROOT=rust node scripts/publish-crate.mjs
+
+# Via CLI argument
+node scripts/publish-crate.mjs --rust-root rust
+```
+
+### Workflow Configuration
+For multi-language repos, ensure your workflow has the correct `working-directory`:
+```yaml
+defaults:
+  run:
+    working-directory: rust
+
+steps:
+  - name: Publish to Crates.io
+    working-directory: .  # Override for scripts that handle paths themselves
+    run: node rust/scripts/publish-crate.mjs
+```
+
+### Reference

+

+
+## General Debugging Tips
+
+### 1. Check Job Dependencies
+View the workflow graph in GitHub Actions to see which jobs depend on which.
+
+### 2. Download Full Logs
+```bash
+gh run view <run-id> --repo owner/repo --log > ci-logs.txt
+```
+
+### 3. Enable Debug Logging
+Add this secret to enable debug logging:
+- Name: `ACTIONS_STEP_DEBUG`
+- Value: `true`
+
+### 4. Check crates.io Status
+Sometimes crates.io has issues. Check: https://status.crates.io/
+
+### 5. Verify Package Locally
+Before pushing, verify your package builds and passes checks:
+```bash
+cargo fmt --all -- --check
+cargo clippy --all-targets --all-features
+cargo test --all-features
+cargo package --list
+```

+#!/usr/bin/env rust-script
+//! Check if a release is needed based on changelog fragments and version state
+//!
+//! This script checks:
+//! 1. If there are changelog fragments to process
+//! 2. If the current version has already been published to crates.io
+//! 3. If the matching GitHub release and configured Docker Hub image tag exist
+//!
+//! IMPORTANT: This script checks external release artifacts, NOT git tags.
+//! This is critical because:
+//! - Git tags can exist without the package being published
+//! - GitHub releases create tags but do not publish to crates.io or Docker Hub
+//! - A crates.io publish can succeed while later Docker/GitHub release steps fail
+//!
+//! Supports both single-language and multi-language repository structures:
+//! - Single-language: Cargo.toml in repository root
+//! - Multi-language: Cargo.toml in rust/ subfolder
+//!
+//! Usage: rust-script scripts/check-release-needed.rs [--rust-root <path>]
+//!
+//! Environment variables:
+//!   - HAS_FRAGMENTS: 'true' if changelog fragments exist (from get-bump-type.rs)
+//!   - DOCKERHUB_IMAGE: Optional Docker Hub image name to verify (namespace/repository)
+//!   - GITHUB_REPOSITORY: GitHub repository to verify (owner/repository)
+//!
+//! Outputs (written to GITHUB_OUTPUT):
+//!   - should_release: 'true' if a release should be created
+//!   - skip_bump: 'true' if version bump should be skipped while missing artifacts are recreated
+//!   - crate_published: 'true' if the current version already exists on crates.io
+//!   - dockerhub_required: 'true' if Docker Hub publishing is configured and a Dockerfile exists
+//!   - dockerhub_published: 'true' if the configured Docker Hub tag exists
+//!   - github_release_published: 'true' if the matching GitHub release exists
+//!   - max_published_version: the highest non-yanked version on crates.io (for downstream use)

+//! - Skips check for automated release branches (changelog-manual-release-*)
+//!
+//! Usage: rust-script scripts/check-version-modification.rs

+//!   - GITHUB_HEAD_REF: The head branch name for PRs
+//!   - GITHUB_BASE_REF: The base branch name for PRs
+//!   - GITHUB_EVENT_NAME: Should be 'pull_request'

+#!/usr/bin/env rust-script
+//! Detect code changes for CI/CD pipeline
+//!
+//! This script detects what types of files have changed in the latest commit
+//! and outputs the results for use in GitHub Actions workflow conditions.
+//!
+//! Key behavior:
+//! - For PRs: detects GitHub Actions' synthetic merge commit and uses
+//!   HEAD^2^..HEAD^2 to get the per-commit diff of the actual PR head,
+//!   so a commit touching only non-code files correctly skips CI jobs
+//!   even when earlier commits in the same PR touched code files.
+//! - For pushes: compares HEAD against HEAD^
+//! - Excludes certain folders and file types from "code changes" detection
+//!
+//! Excluded from code changes (don't require changelog fragments):
+//! - Markdown files (*.md) in any folder
+//! - changelog.d/ folder (changelog fragments)
+//! - docs/ folder (documentation)
+//! - experiments/ folder (experimental scripts)
+//! - examples/ folder (example scripts)
+//!
+//! Usage: rust-script scripts/detect-code-changes.rs
+//!
+//! Environment variables (set by GitHub Actions):
+//!   - GITHUB_EVENT_NAME: 'pull_request' or 'push'
+//!
+//! Outputs (written to GITHUB_OUTPUT):
+//!   - rs-changed: 'true' if any .rs files changed
+//!   - toml-changed: 'true' if any .toml files changed
+//!   - mjs-changed: 'true' if any .mjs files changed
+//!   - docs-changed: 'true' if any .md files changed
+//!   - workflow-changed: 'true' if any .github/workflows/ files changed
+//!   - any-code-changed: 'true' if any code files changed (excludes docs, changelog.d, experiments, examples)

+#!/usr/bin/env rust-script
+//! Bump version in Cargo.toml and commit changes
+//! Used by the CI/CD pipeline for releases
+//!
+//! IMPORTANT: This script checks crates.io (the source of truth for Rust packages),
+//! NOT git tags. This is critical because:
+//! - Git tags can exist without the package being published
+//! - GitHub releases create tags but don't publish to crates.io
+//! - Only crates.io publication means users can actually install the package
+//!
+//! Supports both single-language and multi-language repository structures:
+//! - Single-language: Cargo.toml and changelog.d/ in repository root
+//! - Multi-language: Cargo.toml and changelog.d/ in rust/ subfolder
+//!
+//! Usage: rust-script scripts/version-and-commit.rs --bump-type <major|minor|patch> [--description <desc>] [--rust-root <path>] [--tag-prefix <prefix>] [--release-label <label>]
+//!
+//! ```cargo
+//! [dependencies]
+//! regex = "1"
+//! chrono = "0.4"
+//! ureq = "2"
+//! serde = { version = "1", features = ["derive"] }
+//! serde_json = "1"

+//! Wait for a crates.io package version to become visible.
+//!
+//! The Docker release step runs after `cargo publish`, but crates.io indexing can
+//! lag briefly. Waiting here makes Docker Hub tags and GitHub releases point at a
+//! crate version that users can already resolve.
+//!
+//! Usage:
+//!   rust-script scripts/wait-for-crate.rs --release-version <version>
+//!
+//! Optional arguments:
+//!   --crate-name <name>       Crate name. Defaults to Cargo.toml package name.
+//!   --rust-root <path>        Root containing Cargo.toml. Defaults to auto-detect.
+//!   --max-attempts <count>    Defaults to 30.
+//!   --sleep-seconds <count>   Defaults to 10.
+//!
+//! Outputs (written to GITHUB_OUTPUT):
+//!   - crate_available: 'true' when the version is visible, or 'skipped' for template defaults
+//!
+//! ```cargo
+//! [dependencies]
+//! regex = "1"
+//! ureq = "2"
+//! ```
