From 5e78e7b42aa8769afd24aed96d0bbb1be73f1573 Mon Sep 17 00:00:00 2001 From: Andhi Jeannot Date: Fri, 22 May 2026 12:55:15 -0500 Subject: [PATCH 1/4] Update archcheck tool to use new rules file path and add suppression handling` **Details:** - **Rules file path:** Changed from `specs/009-constitution-compliance/contracts/structural-rules.yaml` to `tools/archcheck/rules.yaml` for centralized rule management. - **Suppression flags:** Added `--suppressions` to specify suppression files, and `--no-suppress` to bypass suppression logic entirely. - **Formatting:** Adjusted `--format` and `--report` flags for flexibility in output. - **Exit code:** Updated to handle suppressed violations gracefully (exit code 1 for violations, 0 for compliance). **Impact:** - Ensures consistent rule enforcement across the tool. - Provides flexibility for suppression rules while maintaining compliance checks. - Improves usability by allowing customization of output formats and suppression behavior. --- .github/workflows/ci.yml | 32 +-- .gitignore | 2 + .golangci.yml | 31 +- .specify/init-options.json | 2 +- .specify/integrations/claude.manifest.json | 14 +- .specify/integrations/pi.manifest.json | 14 +- .specify/integrations/speckit.manifest.json | 14 +- .specify/memory/constitution.md | 6 +- Taskfile.yml | 5 + ...-tighten-outer-layer-entity-import-rule.md | 62 ++++ scripts/benchmark-archcheck.sh | 55 ++++ scripts/check-rules-sync.sh | 94 ++++++ scripts/coverage-delta.sh | 73 +++++ .../checklists/requirements.md | 37 +++ .../contracts/archcheck-cli.md | 134 +++++++++ .../contracts/structural-rules.yaml | 162 +++++++++++ .../contracts/suppression-file-schema.yaml | 92 ++++++ .../contracts/violation-report.schema.json | 109 +++++++ .../010-constitution-compliance/data-model.md | 161 +++++++++++ specs/010-constitution-compliance/plan.md | 138 +++++++++ .../010-constitution-compliance/quickstart.md | 160 +++++++++++ specs/010-constitution-compliance/research.md | 179 ++++++++++++ specs/010-constitution-compliance/spec.md | 148 ++++++++++ specs/010-constitution-compliance/tasks.md | 272 ++++++++++++++++++ tools/archcheck/main.go | 30 +- 25 files changed, 1975 insertions(+), 51 deletions(-) create mode 100644 docs/adr/0010-tighten-outer-layer-entity-import-rule.md create mode 100755 scripts/benchmark-archcheck.sh create mode 100755 scripts/check-rules-sync.sh create mode 100755 scripts/coverage-delta.sh create mode 100644 specs/010-constitution-compliance/checklists/requirements.md create mode 100644 specs/010-constitution-compliance/contracts/archcheck-cli.md create mode 100644 specs/010-constitution-compliance/contracts/structural-rules.yaml create mode 100644 specs/010-constitution-compliance/contracts/suppression-file-schema.yaml create mode 100644 specs/010-constitution-compliance/contracts/violation-report.schema.json create mode 100644 specs/010-constitution-compliance/data-model.md create mode 100644 specs/010-constitution-compliance/plan.md create mode 100644 specs/010-constitution-compliance/quickstart.md create mode 100644 specs/010-constitution-compliance/research.md create mode 100644 specs/010-constitution-compliance/spec.md create mode 100644 specs/010-constitution-compliance/tasks.md diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index c2f9e7a..35cf5f3 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -75,25 +75,21 @@ jobs: - name: Checkout uses: actions/checkout@v4 - - name: Run constitution audit - run: | - chmod +x scripts/audit-constitution.sh - ./scripts/audit-constitution.sh - # continue-on-error so the output is always visible even when violations exist - continue-on-error: true + - name: Set up Go + uses: actions/setup-go@v5 + with: + go-version: '1.25' - - name: Enforce constitution (fail on violations) - run: | - echo "Constitution audit: Enforcing handler size limits..." - if ./scripts/audit-constitution.sh;

The refactor is behaviour-preserving: command names, flags, exit codes, produced files, and MCP tool input/output schemas are byte-equivalent across the change. A small suppression mechanism (file-scoped, owner-tagged, dated) is added so the gate can land green on `main` without first requiring a separate sweep of pre-existing violations outside the named scope. + +## Technical Context + +**Language/Version**: Go 1.25+ (matches `go.mod`) +**Primary Dependencies**: cobra + viper (CLI), lipgloss (TUI), fsnotify (watcher), d2 CLI (behind `DiagramRenderer` port), ason (behind `TemplateEngine` port), TOON v3 (behind `OutputEncoder` port). New for this feature: a Go AST-based custom audit tool (`tools/archcheck`, already scaffolded under feature 009 — extended here) and `golangci-lint depguard` rule (already in toolchain via `task lint`). No new third-party runtime dependency. +**Storage**: filesystem only (`loko.toml`, `relationships.toml`, `*.md`, `dist/*.d2` artefacts). Refactor adds no storage. The compliance check uses a small YAML rule file (`specs/010-constitution-compliance/contracts/structural-rules.yaml`) and a suppression file (`.archcheck-suppressions.yaml` at repo root). +**Testing**: `go test ./...` for unit + integration; existing CLI smoke tests under `tests/integration/cli/`; MCP tool tests under `internal/mcp/tools/*_test.go`; new audit-tool tests under `tools/archcheck/*_test.go` (`go test ./tools/archcheck/...`). +**Target Platform**: macOS / Linux developer workstations and CI runners (GitHub Actions Ubuntu); single static Go binary for `loko`; `tools/archcheck` is a separate small build-time binary. +**Project Type**: single repository — Go monorepo with three consumer interfaces (CLI, MCP server, HTTP API) over a shared core (entities + use cases + adapter ports). +**Performance Goals**: structural compliance check runs in **< 30 s** on a contributor laptop (SC-009); per-file AST parse and per-file dependency-graph evaluation amortised across worker goroutines if needed. +**Constraints**: pure refactor — **no observable behaviour change** (FR-015); test coverage of touched packages must not decrease (FR-016); CI gate must produce file-line-rule diagnostics good enough that a contributor unfamiliar with the project can act on the failure without consulting docs (SC-010). +**Scale/Scope**: ~30–50 production files touched across `cmd/`, `internal/mcp/tools/`, `internal/core/usecases/`, `internal/core/entities/`; one new tool package (`tools/archcheck`); one new contract directory (`contracts/`); one new CI step; one constitution amendment (1.1.0 → 1.2.0) to tighten the outer-layer rule (see Constitution Check below). + +## Constitution Check + +*GATE: Must pass before Phase 0 research.

Interface-First | ✅ PASS | New use cases consume existing ports (`ProjectRepository`, `TemplateEngine`, `DiagramRenderer`, `OutputEncoder`); no new ports introduced (no new external dependency). | +| III. Thin Handlers | ✅ PASS by construction | FR-001 (CLI ≤ 50 eff lines/function), FR-002 (MCP ≤ 30 eff lines/function), and FR-011 (decompose oversized MCP handlers) mirror this principle exactly. | +| IV. Entity Validation | ✅ PASS | No validation logic moves into use cases or handlers. Entity constructors remain authoritative. | +| V. Test-First | ✅ PASS | New use cases land with unit tests using concrete mock ports; new `tools/archcheck` rules land with table-driven tests over fixture trees; FR-016 forbids coverage regression. | +| VI. Token Efficiency | ✅ PASS (out of scope) | No change to output formats or MCP responses; refactor is structural only. | +| VII. Simplicity & YAGNI | ⚠ TENSION → JUSTIFIED | The suppression mechanism (FR-017) is a new piece of infrastructure that did not exist before. Justified because without it the CI gate cannot be turned green on `main` without first executing a wider, unbounded clean-up. See Complexity Tracking. | +| Architecture Rules — File-Size Budgets | ✅ PASS | FR-003 (use-case ≤ 200), FR-004 (entity ≤ 300) mirror the rules table verbatim. | +| Architecture Rules — Dependency Direction | ⚠ TENSION → REQUIRES AMENDMENT | Spec FR-008 forbids direct entity-layer imports from **all three** outer entry-points (`cmd/`, `internal/mcp/`, `internal/api/`). Constitution v1.1.0 forbids it only for `cmd/`. This feature must either (a) ship a constitution amendment to v1.2.0 that tightens `internal/mcp/` and `internal/api/`, or (b) scope FR-008 down to match v1.1.0. Decision: ship the amendment as a deliverable of this feature (see Complexity Tracking + research.md R7). | +| Quality Gates — Before Every Commit | ✅ PASS | New `depguard` config strengthens, does not replace, existing `task lint`. | +| Quality Gates — Before Every PR | ✅ PASS | This feature *adds* the `task audit-constitution` gate; nothing existing weakens. | + +**Verdict**: gates pass under the documented amendment plan. Proceed to Phase 0. + +### Post-Phase-1 Re-evaluation + +Re-checked after Phase 1 artefacts (research.md, data-model.md, contracts/, quickstart.md) were written: + +- **No new principle violations introduced by the design.** The `tools/archcheck` extensions remain outside `internal/` and so are not bound by the dependency-direction rules; the new rule and suppression file formats are pure data. +- **Suppression mechanism (FR-017)** is now fully scoped in `contracts/suppression-file-schema.yaml` and `data-model.md`: 90-day hard cap, owner-tagged, expiry-as-failure semantics. The Simplicity & YAGNI tension flagged before Phase 0 stays at "JUSTIFIED" — the design does not grow the mechanism beyond what FR-017 requires. +- **Constitution amendment 1.1.0 → 1.2.0** remains a planned deliverable; the rule set in `contracts/structural-rules.yaml` already encodes the v1.2.0 outer-layer-tightening, so the amendment and the enforcement land atomically (`research.md R7`). +- **No new ports introduced.** The use cases extracted from `cmd/new.go` and `cmd/build.go` consume existing ports only (`ProjectRepository`, `TemplateEngine`, `DiagramRenderer`, `OutputEncoder`); Interface-First is satisfied without extension. + +Gates remain green.

Reusing the same definition prevents two competing "what counts as a line?" answers in the codebase. The constitution version pins it (one source of truth). + +**Alternatives considered**: +- *Raw `wc -l`*: fails because it punishes commenting; would discourage docstrings. +- *Tokens-per-function instead of lines*: more precise but harder for a reviewer to eyeball; rejected for ergonomics. +- *AST node count*: same ergonomic problem. + +--- + +## R2 — How to enforce the rules: custom AST tool, off-the-shelf linter, or both? + +**Decision**: Use both, with clearly separated roles: +1. `tools/archcheck` (custom Go AST binary) is the **authoritative** check. It owns: per-function effective-line budgets (CLI ≤ 50, MCP ≤ 30), per-file effective-line budgets (use-case ≤ 200, entity ≤ 300), layer-import rules, categorical exemptions, suppression-file evaluation, and machine-readable violation reports. +2. `golangci-lint depguard` is a **redundant fast-path** check that catches layer-import violations during normal lint runs. It is intentionally narrower than `archcheck` (it cannot do per-function line counting or categorical exemptions), but it catches the most common class of regression (a casual import in the wrong direction) instantly during `task lint`. + +**Rationale**: A single off-the-shelf linter cannot do all of: per-function effective-line counts with the exact convention from R1, file-size budgets restricted to specific glob patterns, categorical filename exemptions (`*_cobra.go`, `*_test.go`, generated headers), and a suppression file. A custom tool can. But running an AST-aware tool on every save is heavy; `depguard` is fast enough to live inside the normal lint pass and catches the most common mistake instantly. + +**Alternatives considered**: +- *`go-arch-lint` (only)*: cannot do per-function effective-line budgets; rules use yet another DSL we'd have to learn and maintain. +- *`depguard` (only)*: cannot do line budgets at all. +- *`archcheck` (only, no depguard)*: doubles developer feedback latency for the most common mistake (cross-layer import) because it would only fire during `task audit-constitution`, not during `task lint`. + +--- + +## R3 — `depguard` configuration for layer rules + +**Decision**: Encode the dependency-direction table from the constitution as one `depguard` rule per layer. Each rule names a list of allowed import patterns and an explicit `deny` for the forbidden patterns. Patterns are package import paths under `github.com/madstone-io/loko/…` (or whatever module path `go.mod` declares). The configuration lives in `.golangci.yml` and is the runtime artefact; `specs/010-constitution-compliance/contracts/structural-rules.yaml` is the human-readable mirror that ships with the spec and is referenced by the constitution governance footer. + +**Rationale**: `depguard` v2 supports per-file-glob rule scoping (so the rule for `internal/core/entities/` only applies to those files), pattern-based allow/deny lists, and rich diagnostic messages. It is already a `golangci-lint` plugin in the project's toolchain. The runtime YAML is duplicated by design so the spec stays self-contained. + +**Alternatives considered**: +- *`gomodguard`*: oriented toward module-level allowlists, not directory-level layer rules; awkward fit. +- *Hand-rolled `go list` parser*: reinvents `depguard` with no benefit. +- *Putting the rules only in `archcheck` (no `depguard`)*: see R2 — loses fast-path feedback during `task lint`. + +--- + +## R4 — Suppression mechanism (FR-017) design + +**Decision**: A single repo-root file `.archcheck-suppressions.yaml` enumerates each suppression entry as `{ rule, file, owner, expires_on, reason }`. The audit tool loads it at start, normalises paths, and silently drops matching violations from the failure report while still printing them under a "Suppressed (will fail after expiry)" footer. Any entry whose `expires_on` is in the past is converted back into a normal failure (the gate fails). Entries cannot be wildcarded across rules (`rule` is required and specific); they may use file globs to cover a small cluster of related files. + +**Rationale**: A flat, single-file design is the lightest weight option that still satisfies the audit-quality requirements (owner + expiry, surface in tooling, not silent). Expiry-as-failure trick converts the suppression file into a self-cleaning ledger: an unmaintained suppression eventually becomes a CI failure, forcing either renewal or fix. + +**Alternatives considered**: +- *Inline `//nolint:archcheck-XYZ`-style pragmas*: scatters suppression across the codebase, no central ledger, easy to forget. +- *Per-rule allowlist files*: more files, more boilerplate, no advantage. +- *No suppression mechanism* (force a full clean-up first): rejected — see Complexity Tracking justification in plan.md. + +--- + +## R5 — CI integration approach + +**Decision**: Add one new job step `Audit constitution` to `.github/workflows/ci.yml`, which runs `task audit-constitution`. The task builds `tools/archcheck` (cached across runs) and invokes it with the structural-rules YAML and the suppressions file. The step is **required** for the branch protection rules of `main`; failure blocks the merge button. Existing `Build` and `Test` jobs are not modified. The audit step also publishes the JSON violation report as a workflow artefact so a contributor can download it instead of scrolling through logs. + +**Rationale**: One additional step is the smallest possible change to the existing CI; it composes cleanly with the existing `Test` and `Lint` steps without reordering them. Branch protection — not workflow YAML — is what makes the step gating, matching the existing pattern for `Test`. + +**Alternatives considered**: +- *Run `archcheck` inside the `Lint` step*: couples two distinct concerns and makes failures harder to attribute on the run summary page. +- *Run `archcheck` as a pre-commit hook only*: leaves the gate at the wrong level (developer machine, not CI); easy to bypass with `--no-verify`. + +--- + +## R6 — Test-coverage gating + +**Decision**: FR-016 ("coverage must not decrease for touched packages") is enforced by a small CI script that runs `go test -coverprofile=cover.out ./...`, parses the per-package coverage with `go tool cover`, and compares each touched package's number against the value recorded at the merge-base of the PR. A regression beyond a 0.5-pp tolerance fails the CI job. The list of "touched packages" is computed from `git diff --name-only $merge_base`. + +**Rationale**: Treats coverage as a per-package floor rather than a global one. A global floor would mask a major regression in one package by improvements in another; the per-package floor matches the spec's intent ("packages touched by the refactor"). + +**Alternatives considered**: +- *Global floor only*: rejected — masks per-package regressions. +- *Codecov / Coveralls*: adds a third-party dependency to the gating path; current tooling can do this in ~30 lines of bash + `go tool cover`. + +--- + +## R7 — Constitution amendment v1.1.0 → v1.2.0 + +**Decision**: Ship a constitution amendment as part of this feature.

The constitution version goes to **1.2.0** (MINOR — tightens a principle's surface area without redefining it incompatibly with the principle's existing intent). + +**Rationale**: The user's feature description names all three outer entry-points as bound by the no-direct-entity-import rule. Feature 009 deliberately deferred the mcp/api tightening to keep that feature's scope narrow; this feature owns the deferred work. Doing the amendment under 010 closes the gap noted in the v1.1.0 SYNC IMPACT REPORT ("Tightening that is a future-feature concern"). + +**Alternatives considered**: +- *Scope FR-008 down to `cmd/` only*: rejected — user-stated requirement is broader; would leave the same can-kick for a third feature. +- *Ship the amendment under a separate constitution-only PR*: rejected — amendment and the code it enables must land together to avoid a window in which the rule is in the constitution but unenforced. + +--- + +## R8 — Decomposition strategy for `cmd/new.go` (504 lines) + +**Decision**: The handler `cmd/new.go` is split into: +- `cmd/new.go` (orchestration only; one Cobra `RunE` per subcommand, each ≤ 50 effective lines): parses flags, loads config, dispatches to a use case, renders output. +- `internal/core/usecases/scaffold_project.go`: top-level project scaffold (creates project root, `loko.toml`, top-level layout). +- `internal/core/usecases/scaffold_system.go`: add-system flow. +- `internal/core/usecases/scaffold_container.go`: add-container flow (under a chosen system). +- `internal/core/usecases/scaffold_component.go`: add-component flow (under a chosen container). + +Each use-case file is targeted ≤ 200 effective lines (FR-003). If a single scaffold flow exceeds the budget, it is split further by sub-step (e.g., `scaffold_project_files.go` for the file-writing sub-step) — splits are deliberate and cohesion-preserving, not mechanical. + +**Rationale**: The four-way split mirrors the four logical subcommands of `loko new` (`project | system | container | component`); each file is then independently testable with concrete mock `ProjectRepository` + `TemplateEngine` ports. This matches the constitution's "interface-first" principle and the spec's "narrative coherence" acceptance scenario (Story 4 AS3). + +**Alternatives considered**: +- *Single big `scaffold.go` with internal sub-functions*: would itself exceed 200 lines; defeats the purpose. +- *One file per public method (`scaffold_new_project`, `scaffold_new_system`…)*: same as the chosen split; semantically equivalent. + +--- + +## R9 — Decomposition strategy for `cmd/build.go` (251 lines) + +**Decision**: `cmd/build.go` becomes a thin Cobra `RunE` that parses flags and delegates to an existing/extended `internal/core/usecases/build_docs.go`. The existing companion files (`build_docs_diagrams.go`, `build_docs_tables.go`) absorb their respective sub-step logic that today lives inline in `cmd/build.go`. Any further sub-step that pushes `build_docs.go` past 200 effective lines is split into a new `build_docs_.go` sibling (e.g., `build_docs_render.go`, `build_docs_assets.go`). + +**Rationale**: `build_docs.go` is the natural home for build orchestration; the file family already exists, so this is incremental rather than greenfield. The split-by-sub-step pattern is the one the constitution's File-Size Budgets row explicitly suggests as an example. + +**Alternatives considered**: +- *One monolithic `build_docs.go`*: would exceed 200 lines; rejected by FR-003. +- *Class-style "Builder" type with methods spread across files*: more ceremony than needed; the project consistently uses free functions over structs-with-methods for use cases. + +--- + +## R10 — MCP-tool decomposition strategy + +**Decision**: For every MCP tool handler currently exceeding 30 effective lines, the per-tool file structure becomes: +- The handler function (≤ 30 eff lines): unmarshal protocol input → call a use case → marshal protocol output. +- A small "request" struct + "response" struct that owns nothing but JSON tags (lives in the same file or a sibling `*_schemas.go` — `*_schemas.go` is a categorically exempt data-file under Principle III). +- Domain logic moves to an `internal/core/usecases/` use case (creating a new one if no existing use case fits — see R8/R9 patterns). + +If two MCP tools share a use case (likely for `build_docs` and the CLI's `build`), the use case is written once and called by both adapters. This is the constitution's "three interfaces share one core" promise in action. + +**Rationale**: Standard MCP-adapter pattern matching constitution Principle III. The schemas-file carve-out is already enshrined in the categorical exemptions (`schemas.go`, `registry.go`, `helpers.go`, `constants.go`) so no new exemption is needed. + +**Alternatives considered**: +- *Inline JSON-unmarshal calls in handler*: violates the 30-eff-line budget on tools with non-trivial schemas. +- *One mega-file per tool category*: defeats the per-handler budget and hurts grep-ability. + +--- + +## R11 — Behaviour preservation verification + +**Decision**: Behaviour preservation (FR-015) is verified by three layers: +1. **Unit tests**: existing per-package tests must all stay green. +2. **CLI golden-file tests** (under `tests/integration/cli/`): for each CLI command in scope, capture pre-refactor `stdout + stderr + exit-code + tree-of-files-produced` into a golden file; the test re-runs the command and diffs against the golden file. +3. **MCP smoke tests** (`specs/010-constitution-compliance/mcp-smoke.md`): for each MCP tool, a small JSON-RPC fixture is replayed against the running server and the response is byte-compared to a pre-refactor capture. + +The golden files and JSON fixtures are captured **before** any production code is moved, so the diff at the end of the refactor is genuinely a refactor signal, not an accidental retrofit. + +**Rationale**: Three layers because each catches a different class of regression: unit tests catch logic bugs, golden-file tests catch shell-surface regressions (a printf format that drifts), MCP smoke tests catch protocol-surface regressions. + +**Alternatives considered**: +- *Unit tests only*: misses shell- and protocol-surface drift, which is exactly the failure mode a "no observable behaviour change" refactor is supposed to prevent. +- *Big-bang manual QA at the end*: not reproducible, not scalable, not what FR-016 asks for. + +--- + +*All NEEDS CLARIFICATION items from the plan's Technical Context are resolved above.

Rationale: the project already uses Taskfile.yml as the canonical entry point for `task test`, `task lint`, `task build`, `task setup`; adding a `make`-based command would split the toolchain. (Plan-level detail; recorded here for traceability — does not change any functional requirement.) + +## User Scenarios & Testing *(mandatory)* + +### User Story 1 - Bring Oversized CLI Handlers Within the Architectural Budget (Priority: P1) + +As a maintainer, I need every command-line entry point to be a thin orchestration layer that delegates real work to the core domain, so the project's architectural constitution is honoured at the most-trafficked entry points of the product. Today, the project-scaffolding command and the documentation-build command are the two most egregious offenders: each contains the bulk of its logic inline, mixing user-facing concerns with domain logic and infrastructure access. Until they are decomposed, contributors will keep copying that pattern when adding new commands. + +**Why this priority**: These two handlers are the largest and most visible violations called out in the production design document. Fixing them establishes the canonical "thin CLI handler → core use case" pattern that the rest of the refactor depends on, and it unblocks reuse of the extracted use cases by other layers (MCP, future API). + +**Independent Test**: Run the project's structural compliance checker against the CLI package after the refactor. It reports zero handler-size violations and zero layer-import violations for the two named commands; behavioural tests for those commands all pass; end-users invoking the commands observe identical produced files, console output, exit codes, and error messages. + +**Acceptance Scenarios**: + +1. **Given** the previously oversized scaffolding command, **When** a contributor inspects the handler file, **Then** every handler function fits within the small-handler size budget and all scaffolding logic is reachable from one or more dedicated use cases in the core domain rather than from the command file. +2. **Given** the previously oversized documentation-build command, **When** a contributor inspects the handler file, **Then** every handler function fits within the small-handler size budget and the build orchestration is reachable from a dedicated use case in the core domain rather than from the command file. +3. **Given** a user invoking either of those commands with their full pre-refactor argument set, **When** the command runs to completion, **Then** the produced files, console output, exit code, and error messages are equivalent to the pre-refactor version under the same inputs. +4. **Given** the existing automated test suite, **When** it is run against the refactored code, **Then** every previously passing test still passes and coverage of the touched commands does not decrease. + +--- + +### User Story 2 - Bring Oversized MCP Tool Handlers Within the Strict Per-Handler Budget (Priority: P1) + +As a maintainer, I need every Model-Context-Protocol tool handler to remain a thin adapter that translates between the protocol and a core use case, so protocol-handling code never accumulates business logic. Today, several MCP tool handlers exceed the constitution's strict per-handler size budget, with domain logic inlined into transport code. + +**Why this priority**: MCP tools are an externally exposed surface and an active growth area for the product; future tools will copy whatever pattern is set today. They are co-equal in priority with the CLI work because the MCP server is an independent, user-facing entry point — leaving it non-compliant defeats the purpose of fixing the CLI. + +**Independent Test**: Run the structural compliance checker against the MCP tool package. Zero handlers exceed the per-handler size budget; every tool's domain logic is reachable from a use case in the core domain; the integration tests that exercise each MCP tool over the protocol still pass with byte-equivalent responses for the same inputs. + +**Acceptance Scenarios**: + +1. **Given** every MCP tool handler the project exposes today, **When** the handler files are inspected, **Then** every handler function fits within the strict MCP-handler size budget. +2. **Given** an external client calling any MCP tool, **When** the tool is invoked with its previously supported inputs, **Then** the tool returns results equivalent to the pre-refactor responses for the same inputs. +3. **Given** the existing MCP tool tests, **When** they are run against the refactored handlers, **Then** every previously passing test still passes. + +--- + +### User Story 3 - Enforce Layer and Size Rules Mechanically and Continuously (Priority: P1) + +As a maintainer, I need the layered architecture rules and file-size budgets to be enforced by an automated check that runs locally and in continuous integration, so contributors cannot accidentally re-introduce violations after the one-off refactor lands. Today the rules exist only as prose, and any violation has to be caught manually during review. + +**Why this priority**: Refactoring without a guard is throwaway work — the same violations will reappear within weeks. The mechanical check is what converts the constitution from a guideline into a guarantee. It is co-equal in priority with Stories 1 and 2 because the value of the refactor is fully realised only when regressions are prevented. + +**Independent Test**: On a throwaway branch, introduce one deliberate layer violation (e.g., import the entity layer directly from a CLI command file) and one deliberate file-size violation (e.g., balloon a use-case file past its budget). Run the check locally and open a pull request. Both violations are reported with file, offending entity (function or import path), and the specific rule broken; the pull request is blocked from merging until the violations are removed. + +**Acceptance Scenarios**: + +1. **Given** the entity layer, **When** the check runs, **Then** it fails on any entity-layer file that imports any other internal package of the project. +2. **Given** the use-case layer, **When** the check runs, **Then** it fails on any use-case file that imports anything from internal packages other than the entity layer. +3. **Given** the adapters layer, **When** the check runs, **Then** it fails on any adapter file that imports any internal package other than entities and use cases. +4. **Given** the outer entry-point packages (CLI commands, MCP server, HTTP API server), **When** the check runs, **Then** it fails on any file in those packages that imports the entity layer directly instead of obtaining entity types via adapters or via use-case return values. +5. **Given** any source file in the production codebase, **When** the check runs, **Then** it fails on any file that exceeds the file-size budget for its category. +6. **Given** the project's continuous integration pipeline, **When** a pull request introduces any layer or size violation, **Then** the pipeline fails before the change can be merged into the default branch. + +--- + +### User Story 4 - Keep the Core Layer Compliant After Migration (Priority: P2) + +As a maintainer, I need every use-case file and every entity file in the core domain to stay within its file-size budget after CLI and MCP logic is moved into it, so the refactor does not simply relocate the violations from the outer layers to the core. Without deliberate splitting, the use-case files that absorb the extracted logic will themselves cross the budget. + +**Why this priority**: This story is sequenced after Stories 1–3 because the file-size pressure on the core arrives only once the outer-layer logic has been moved. It is a P2 — not P1 — because if Stories 1–3 land but the core files are slightly oversized at the moment of cutover, the mechanical check from Story 3 will catch it and Story 4 finishes the job in a follow-up commit. The story still must land in-scope of this feature so the gate from Story 3 is actually green on main. + +**Independent Test**: Run the file-size portion of the structural compliance checker against the entity and use-case packages after the refactor. Every use-case file is within the use-case file budget; every entity file is within the entity file budget; reviewers confirm no use case has been chopped so finely that it loses narrative coherence. + +**Acceptance Scenarios**: + +1. **Given** the use-case package after the refactor, **When** the file-size check runs, **Then** every file is within the use-case file budget. +2. **Given** the entity package after the refactor, **When** the file-size check runs, **Then** every file is within the entity file budget. +3. **Given** a logically grouped use case (e.g., "scaffold a new project"), **When** a contributor opens the related files, **Then** related steps live together in cohesive files rather than being scattered across many trivial files just to satisfy the size budget. + +--- + +### Edge Cases + +- A function or file is exactly at its size limit boundary: the rule treats the limit as inclusive (e.g., 50 lines is allowed, 51 is not), and the counting convention used by the check tool (logical lines of code, excluding blank lines and comments) is documented in the project's compliance reference so contributors get the same answer the tool gets. +- A use case is split across multiple files inside one logical package and the package as a whole is large: the file-size budget applies per file, not per package, so well-organised multi-file use cases remain compliant. +- Generated code (e.g., protocol stubs, embedded asset registries) lives in the repository: generated files are exempt from file-size budgets but remain subject to layer-import rules, and the exemption mechanism is explicitly documented so it cannot be abused as a workaround. +- Test files are large because they enumerate many cases: test files are exempt from production-code file-size budgets so growth of test coverage is never penalised. +- A contributor adds a new outer-layer entry point (e.g., a new server or new CLI subcommand) that needs entity types: they must obtain those types via an adapter or a use-case return value, never by importing the entity package directly. The check's failure message tells them this on first attempt. +- The refactor moves a function whose previous name was part of an exported public surface: the externally observable public surface (command names, command-line flags and their help text, MCP tool names, MCP tool input and output schemas, exit codes, log lines that downstream tools may parse) is preserved exactly so external users see no change. +- A test relied on internals that moved during the refactor: the test is updated to call the new internal location, but the behaviour it verifies is unchanged. No test is deleted to make the refactor fit; if a behaviour was tested before, it is still tested after. +- The compliance check itself flags a pre-existing violation that is outside the declared scope of this refactor (e.g., a file owned by a different feature): the check supports a clearly-documented, time-bound suppression mechanism so the gate can be enabled on the main branch without first blocking unrelated work; every active suppression has an owner and a removal deadline. + +## Requirements *(mandatory)* + +### Functional Requirements + +- **FR-001**: Every command-line handler function MUST fit within the small-handler size budget (no handler function exceeds 50 lines under the project's documented counting convention). +- **FR-002**: Every Model-Context-Protocol tool handler function MUST fit within the strict MCP-handler size budget (no MCP tool handler function exceeds 30 lines under the project's documented counting convention). +- **FR-003**: Every use-case file in the core domain MUST fit within the use-case file budget (no use-case file exceeds 200 lines under the project's documented counting convention). +- **FR-004**: Every entity file in the core domain MUST fit within the entity file budget (no entity file exceeds 300 lines under the project's documented counting convention). +- **FR-005**: The entity layer MUST NOT import from any other internal package of the project. +- **FR-006**: The use-case layer MUST NOT import from any internal package other than the entity layer. +- **FR-007**: The adapters layer MUST NOT import from any internal package other than the entity layer and the use-case layer. +- **FR-008**: The outer entry-point packages (CLI commands, MCP server, HTTP API server) MUST NOT import the entity layer directly; they MUST obtain entity types via adapters or via use-case return values. +- **FR-009**: The previously oversized project-scaffolding CLI handler MUST be decomposed so that its scaffolding logic lives in dedicated, narrowly-scoped use cases in the core domain, and the handler itself only parses inputs, calls the use case(s), and renders output. +- **FR-010**: The previously oversized documentation-build CLI handler MUST be decomposed so that its build orchestration lives in a dedicated use case in the core domain, and the handler itself only parses inputs, calls the use case, and renders output. +- **FR-011**: Every Model-Context-Protocol tool handler that previously exceeded the strict handler budget MUST be reduced to a thin protocol adapter that delegates domain logic to a use case. +- **FR-012**: An automated structural-compliance check (covering both file-size budgets and layer-import rules) MUST exist as part of the project's tooling and be runnable locally with a single documented command. +- **FR-013**: The automated structural-compliance check MUST be wired into the project's continuous integration pipeline as a gating check; failures of this check MUST block pull requests from being merged into the default branch. +- **FR-014**: The automated structural-compliance check MUST produce error messages that name, for each violation, the offending file, the offending entity (function name for size violations, import path for layer violations), and the specific rule that was broken. +- **FR-015**: The refactor MUST be behaviour-preserving: command names, command-line flags and their help text, MCP tool names, MCP tool input and output schemas, exit codes, and the contents of files produced by build and scaffolding commands MUST be equivalent before and after the refactor for the same inputs. +- **FR-016**: The existing automated test suite MUST pass against the refactored code, and overall test coverage of the touched packages MUST NOT decrease. +- **FR-017**: The compliance check MUST support a clearly-documented suppression mechanism for pre-existing violations outside the scope of this refactor, where each active suppression carries an owner and a removal date, so the gate can be enabled on the main branch without blocking unrelated work indefinitely. + +### Key Entities *(include if feature involves data)* + +- **Source File Category**: A classification (CLI command, MCP tool handler, use case, entity, adapter, generated, test) used by the compliance check to decide which size budget and which import rules apply to a given file. +- **Layer Rule**: A statement of the form "files in layer X may import only from layers Y, Z, …" that the check evaluates against the import graph of every source file. +- **Size Budget**: A maximum line count, per file or per function, associated with a source-file category and measured under the project's documented counting convention. +- **Violation Report**: A machine- and human-readable record naming the offending file, the offending entity (function for size violations, import path for layer violations), the rule broken, and (for size violations) the measured value versus the budget. +- **Suppression Entry**: A scoped, owner-tagged, dated exemption for a single pre-existing violation that allows the gate to be turned on without blocking work outside this feature's scope. + +## Success Criteria *(mandatory)* + +### Measurable Outcomes + +- **SC-001**: Zero handler-size violations remain in the CLI command package after the refactor, as reported by the structural compliance check. +- **SC-002**: Zero handler-size violations remain in the MCP tool package after the refactor, as reported by the structural compliance check. +- **SC-003**: Zero file-size violations remain in the core domain (use cases and entities) after the refactor, as reported by the structural compliance check. +- **SC-004**: Zero layer-import violations remain anywhere in the production codebase after the refactor, as reported by the structural compliance check. +- **SC-005**: The continuous integration pipeline blocks every pull request that introduces any structural violation, demonstrated by a deliberately-violating test pull request that is correctly rejected. +- **SC-006**: 100% of the project's previously passing automated tests still pass against the refactored code. +- **SC-007**: Test coverage of every package touched by the refactor is greater than or equal to the pre-refactor coverage for that package. +- **SC-008**: Users invoking any CLI command or MCP tool with its pre-refactor inputs observe equivalent outputs (produced files, console output, exit codes, error messages, MCP tool responses) — verified by a smoke-test run against a representative sample of commands and tools. +- **SC-009**: The structural compliance check completes in under 30 seconds on a typical contributor laptop, so it is cheap enough to be run on every save during development. +- **SC-010**: A contributor unfamiliar with the project can read the compliance check's failure message for any violation and locate the offending file and line, and identify the rule that was broken, without consulting additional documentation. + +## Assumptions + +- The constitution version that applies to this refactor is the one described in the Constitution Compliance section of `docs/superpowers/specs/2026-05-08-loko-production-design.md`; the size budgets (50 / 30 / 200 / 300) and the layer rules quoted in the user description are authoritative for the duration of this feature. +- The "counting convention" for handler-function and file-size limits is logical lines of code (excluding blank lines and comment-only lines), computed by the compliance check tool itself; whatever the tool measures is the canonical answer, and any drift between manual estimates and the tool's measurement is resolved in favour of the tool. +- The project's continuous integration pipeline already runs the project's existing lint and test commands and can be extended with one additional gating step without architectural change. +- The MCP server and HTTP API server packages are treated as outer entry-point layers and are required to honour the same "no direct entity-layer import" rule as the CLI commands package; if a prior constitution version exempted any of those, this refactor closes that gap. +- The set of pre-existing structural violations outside the named scope (CLI handlers, MCP tool handlers, core file sizes after migration) is small enough to be addressed either inside this feature or via the documented suppression mechanism — i.e., enabling the CI gate does not require a multi-week separate clean-up effort. +- No new third-party runtime dependency is needed to perform the refactor itself; the compliance check may use existing project tooling, the standard language toolchain, or a small custom tool added to the project's build-time dependencies. +- The refactor lands as a single feature branch merged to the default branch in one or more reviewable pull requests; no flag-guarded rollout is required because the change is internal-only and behaviour-preserving. diff --git a/specs/010-constitution-compliance/tasks.md b/specs/010-constitution-compliance/tasks.md new file mode 100644 index 0000000..8e40a88 --- /dev/null +++ b/specs/010-constitution-compliance/tasks.md @@ -0,0 +1,272 @@ +--- + +description: "Task list for feature 010-constitution-compliance" +--- + +# Tasks: Constitution Compliance Refactor + +**Input**: Design documents from `/specs/010-constitution-compliance/` +**Prerequisites**: plan.md, spec.md, research.md, data-model.md, contracts/, quickstart.md + +**Tests**: Behaviour-preservation tests are MANDATORY (FR-015, FR-016).

At that time, TOON was added as an optional format to the `query_architecture` tool with JSON as the default, because: +1. TOON was a new, unfamiliar format +2. Existing MCP clients consumed JSON +3. The change was additive — no client behavior changed + +Feature 011 proposes making TOON the default output format for all seven MCP read tools (`query_project`, `query_architecture`, `query_dependencies`, `query_related_components`, `search_elements`, `list_relationships`, `analyze_coupling`). This reverses the default for read tools: TOON becomes default, JSON becomes opt-in via `format: "json"`. + +This directly conflicts with Principle VI as currently written. + +### Why the conflict is justified + +The Principle VI default was scoped to **file output and CLI output** — formats that are consumed by humans, scripts, and external tools that expect stable serialization. MCP read-tool responses, by contrast, are: + +1. **Internal to the LLM↔MCP server interaction** — never written to disk, never consumed by external systems +2. **Ephemeral** — each response is consumed immediately by the calling LLM and discarded +3. **Volume-dominant** — read tools are the highest-frequency MCP calls; their responses dominate token spend +4. **Already negotiated** — the MCP transport is JSON-RPC; the *content* of the `result` field is what changes, not the transport encoding + +The original opt-in design in ADR 0003 was conservative because TOON was experimental. Since then, TOON has proven stable, the `toon-go` library is a declared dependency, and the `OutputEncoder` interface has been in production use. The risk of TOON as default for MCP read-tool *content* is materially lower than for file/CLI output. + +### What does NOT change + +This amendment does NOT change the default for: +- CLI output (`loko build --format` defaults remain unchanged) +- File output (architecture documents written to disk) +- Mutation tool responses (still JSON) +- Validation tool responses (still JSON) +- HTTP API responses (JSON default retained) + +## Decision + +Amend Principle VI to narrow the "JSON default" scope: + +> "Default to JSON for compatibility in file output, CLI output, and HTTP API responses.

It currently accepts `"text"`, `"json"`, `"toon"`, `"compact"`. The advertised schema will be updated to `enum: ["toon", "json"]` with `"toon"` as default. `"text"` and `"compact"` remain accepted internally for backward compatibility but map to `"toon"` behavior. + +2. **Should mutation tools silently ignore `format` or error?** + - Resolved: Silently ignore. The `format` parameter is not in their input schemas, so an MCP client cannot pass it without a schema violation. If passed anyway (protocol-level), it is ignored. + +3. **Should the TOON payload be pretty-printed or minified?** + - Resolved: Minified. `toon.Marshal` produces compact output.

Shrinking them is the single largest token-efficiency lever in the product, and it delivers value even if nothing else in this feature lands. + +**Independent Test**: Call each of the seven read tools against the canonical test project with no `format` argument; confirm every response is returned in TOON and that the information content (every element, relationship, count, and field present in the JSON form) is preserved. + +**Acceptance Scenarios**: + +1. **Given** an LLM calls `query_project` with no format argument, **When** the tool returns, **Then** the response body is TOON-encoded and contains the same project, system, container, and component information the JSON form would have contained. +2. **Given** an LLM calls any of the seven read tools, **When** it inspects the response, **Then** the format is TOON by default without the caller having to opt in. +3. **Given** a representative project payload, **When** the same query is answered in TOON versus JSON, **Then** the TOON form uses at least 30% fewer tokens. + +--- + +### User Story 2 - Developer requests JSON for human-readable debugging (Priority: P2) + +A developer (or an MCP client that needs human-readable output) calls a read tool with an explicit `format: "json"` argument and receives the response as JSON, so they can read, diff, or paste it into existing JSON-aware tooling while debugging. + +**Why this priority**: TOON is optimized for token density, not human reading. Without an explicit escape hatch, the default change would make interactive debugging and existing JSON-consuming integrations harder. This makes the new default safe to adopt. + +**Independent Test**: Call each read tool with `format: "json"` and confirm the response is valid JSON equivalent in content to the TOON response; call with `format: "toon"` and confirm TOON; call with an unrecognized format value and confirm a clear error rather than a silent fallback. + +**Acceptance Scenarios**: + +1. **Given** a read tool is called with `format: "json"`, **When** it returns, **Then** the response is valid JSON carrying the same information as the default TOON response. +2. **Given** a read tool is called with `format: "toon"` explicitly, **When** it returns, **Then** the response is TOON (identical to the default). +3. **Given** a read tool is called with an unsupported `format` value, **When** it is processed, **Then** the caller receives a clear error naming the offending value and the allowed values. +4. **Given** a mutation tool (e.g. `create_system`) or a validation tool, **When** it returns, **Then** the response is JSON regardless of any `format` argument, and its behavior is unchanged from today. + +--- + +### User Story 3 - Maintainer proves and guards the token-reduction target (Priority: P3) + +A maintainer runs a repeatable benchmark that measures token counts for TOON versus JSON across representative payloads and reports the percentage reduction, so the 30–40% target can be verified before release and protected against regression over time. + +**Why this priority**: The 30–40% reduction is the feature's headline claim and its acceptance criterion. A reproducible, reviewable benchmark turns that claim from an assertion into an enforced gate, and it fills in the currently-empty results table in the existing methodology doc. + +**Independent Test**: Run the benchmark suite against the representative payload set; confirm it emits per-payload JSON-token, TOON-token, and percentage-reduction figures, and that it fails (non-zero) if the aggregate reduction across the read-tool payloads drops below the agreed threshold. + +**Acceptance Scenarios**: + +1. **Given** the benchmark suite is run, **When** it completes, **Then** it reports JSON tokens, TOON tokens, and percentage reduction for each representative payload and an aggregate figure. +2. **Given** the aggregate reduction is below the minimum acceptance threshold, **When** the benchmark runs in the gating context, **Then** it signals failure. +3. **Given** the benchmark has run, **When** a maintainer opens the methodology results document, **Then** the previously-empty results table is populated with the measured figures. + +--- + +### Edge Cases + +- **Empty or minimal payloads** (e.g. `query_project` on a project with no systems): TOON must still be produced and parseable; very small payloads may show little or no reduction — these are excluded from the gated aggregate (the gate is about representative, non-trivial payloads). +- **Unsupported `format` value**: returns a clear error, never a silent default to the wrong format. +- **Special characters / nesting** in element names, descriptions, narratives, or tags: TOON output must remain well-formed and unambiguously decodable. +- **A read tool whose payload is dominated by long free-text** (e.g. narratives): reduction may be lower than for list-heavy payloads; the suite reports per-payload figures so this is visible rather than hidden in the aggregate. +- **Existing MCP clients that assumed JSON**: behavior changes by default (now TOON); they must opt back into JSON via `format: "json"`. This is an intentional, documented change for read tools (see Assumptions). + +## Requirements *(mandatory)* + +### Functional Requirements + +- **FR-001**: All seven read tools — `query_project`, `query_architecture`, `query_dependencies`, `query_related_components`, `search_elements`, `list_relationships`, `analyze_coupling` — MUST return their responses in TOON when no format is specified. +- **FR-002**: Each read tool MUST accept an optional `format` argument with the allowed values `toon` (default) and `json`. +- **FR-003**: When `format: "json"` is supplied, a read tool MUST return valid JSON whose information content is equivalent to its TOON response (same elements, relationships, counts, and fields). +- **FR-004**: When an unsupported `format` value is supplied, the tool MUST return a clear error that names the rejected value and lists the allowed values, and MUST NOT silently substitute a format. +- **FR-005**: Mutation tools (create/update/delete) and validation tools MUST continue to return JSON, and their outputs MUST be unchanged by this feature regardless of any `format` argument. +- **FR-006**: TOON responses MUST preserve the full information of the equivalent JSON response — no field, element, relationship, or count may be dropped solely because of the format. +- **FR-007**: TOON responses MUST be well-formed and unambiguously decodable for all valid model content, including names, descriptions, narratives, and tags containing special characters or nested structure. +- **FR-008**: Each read tool's declared input schema MUST document the `format` argument, its allowed values, and its default, so MCP clients and LLMs can discover it. +- **FR-009**: A benchmark suite MUST measure and report, per representative payload, the JSON token count, the TOON token count, and the percentage reduction, plus an aggregate across the read-tool payloads, using the methodology documented in `research/token-efficiency-benchmarks.md`. +- **FR-010**: The benchmark suite MUST signal failure when the aggregate token reduction across representative read-tool payloads falls below the minimum acceptance threshold (see Success Criteria), so it can act as a release/CI gate. +- **FR-011**: Running the benchmark MUST populate the results table in `research/token-efficiency-benchmarks.md` (currently empty) with the measured figures. +- **FR-012**: The change MUST be reversible per call — any client can obtain JSON for any read tool by passing `format: "json"` without server reconfiguration. + +### Key Entities *(include if feature involves data)* + +- **Tool response payload**: the data a read tool returns about the architecture model (project, systems, containers, components, relationships, dependency/coupling reports, search results). Format-independent in content; rendered as either TOON or JSON. +- **Format selector**: the per-call choice of output notation (`toon` or `json`), defaulting to `toon`. +- **Benchmark payload set**: the representative model payloads used to measure token efficiency, drawn from the example projects already referenced by the existing methodology and the canonical test project. + +## Success Criteria *(mandatory)* + +### Measurable Outcomes + +- **SC-001**: Across the representative read-tool payloads, TOON responses use **at least 30%** fewer tokens than the equivalent JSON responses (target band 30–40%), measured by the documented methodology. +- **SC-002**: All seven named read tools return TOON by default and JSON on request; 100% of them support both formats. +- **SC-003**: Mutation and validation tool outputs are unchanged from before the feature (0 regressions in their responses). +- **SC-004**: An invalid `format` value yields an actionable error in 100% of cases, with no silent format substitution. +- **SC-005**: The benchmark suite is reproducible (same inputs produce the same reported reduction figures) and is wired into the project's automated gate so a drop below the threshold fails the build. +- **SC-006**: The results table in the methodology document is populated with current measured figures rather than empty. +- **SC-007**: A maintainer can verify the headline reduction claim end-to-end by running a single benchmark command and reading its output, without inspecting implementation internals. + +## Assumptions + +- **The `format` argument is a per-call tool parameter**, not a session-level or environment-level setting. This matches how MCP tools expose options and lets a single client mix TOON and JSON across calls. (Candidate for `/speckit.clarify` if a global/session toggle is preferred.) +- **TOON becomes the default for read tools, which is an intentional behavior change** for existing MCP clients; clients that require JSON opt in via `format: "json"`. The feature description states this explicitly. +- **A TOON encoding capability already exists** in the project (an output-encoder abstraction with a TOON implementation, already used by the build pipeline). This feature applies it to MCP read-tool responses; it does not introduce a new TOON library (`toon-go` is already a dependency). +- **The representative benchmark payload set** is the example projects referenced by `research/token-efficiency-benchmarks.md` plus the canonical test project, exercised through the seven read tools. (Exact dataset composition is a `/speckit.clarify` candidate.) +- **Token counting uses the approximation already documented** in the methodology doc (≈4 characters per token for structured data) unless a more precise tokenizer is later chosen; the gate is expressed as a percentage reduction so it is robust to the estimator choice. +- **The 30–40% figure is a target band**; the hard gate is the lower bound (≥30%) to avoid flapping when a payload happens to land at the band's edge. +- **Mutation/validation tools are out of scope** for format changes because their payloads are small and their JSON outputs are relied upon elsewhere. +- **No change to the MCP transport, tool names, or call signatures** beyond adding the optional `format` argument to the seven read tools. diff --git a/specs/011-toon-mcp-output/tasks.md b/specs/011-toon-mcp-output/tasks.md new file mode 100644 index 0000000..18195e2 --- /dev/null +++ b/specs/011-toon-mcp-output/tasks.md @@ -0,0 +1,222 @@ +# Tasks: TOON Output Format for MCP Query Tools + +**Input**: Design documents from `/specs/011-toon-mcp-output/` +**Prerequisites**: plan.md (required), spec.md (required for user stories), research.md, data-model.md, contracts/mcp-tool-format.md + +**Tests**: Tests are REQUIRED per the specification's "Independent Test" criteria and the constitution's Test-First principle.

This broke CI compilation of the archcheck tool, which in turn failed the Test, Lint, and Constitution Audit jobs. Also force-add .archcheck-suppressions.yaml which contains the initial constitution v1.2.0 suppression entries and was similarly ignored. --- .archcheck-suppressions.yaml | 80 +++++++++++++ tools/archcheck/rules.yaml | 167 +++++++++++++++++++++++++++ tools/archcheck/suppression.go | 169 ++++++++++++++++++++++++++++ tools/archcheck/suppression_test.go | 141 +++++++++++++++++++++++ 4 files changed, 557 insertions(+) create mode 100644 .archcheck-suppressions.yaml create mode 100644 tools/archcheck/rules.yaml create mode 100644 tools/archcheck/suppression.go create mode 100644 tools/archcheck/suppression_test.go diff --git a/.archcheck-suppressions.yaml b/.archcheck-suppressions.yaml new file mode 100644 index 0000000..85aa16f --- /dev/null +++ b/.archcheck-suppressions.yaml @@ -0,0 +1,80 @@ +# Suppressions for archcheck (loko constitution compliance check). +# +# Each entry is a scoped, owner-tagged, dated exemption for a pre-existing +# violation that cannot be fixed within the current feature's scope.
