Summary

  • define cargo theorem as the single Cargo-native entry point, replacing the
    proposed theoremd surface
  • specify OrthoConfig-backed agent-native command and configuration contracts,
    safe scaffolding, and build-script integration
  • absorb Kani and Verus workflows from rust-prover-tools behind backend
    providers
  • add dependency-ordered roadmap slices for CLI foundation, project mutation,
    backend management, execution, reporting, and migration
  • index the new design document

Notable decisions

  • use a dedicated cargo-theorem application crate
  • retain Rust 1.88 for theoremc libraries while the CLI uses Rust 1.89 to match
    ortho_config 0.9.0
  • keep backend installation explicit: check, build-script run, and run
    never install tools
  • define strict JSON stdout and stderr invariants, bounded responses, stable
    exit classes, durable run records, and dry-run and idempotency contracts
  • retire rust-prover-tools only after cross-platform parity gates pass

Validation

  • parsed all changed Markdown as CommonMark
  • checked heading-level progression and the repository line-length policy
  • compared uploaded Git blob identifiers with the locally validated files
  • reviewed the Mermaid source and relative documentation links

Summary by Sourcery

Define the proposed Cargo-native cargo theorem CLI as the unified interface for theoremc project management, backend workflows, execution, and reporting.

New Features:

  • Define a single Cargo-native cargo theorem entry point and its command, configuration, output, mutation, execution, reporting, and agent-context contracts.
  • Specify backend-provider interfaces and migration paths for Kani and Verus workflows previously provided by rust-prover-tools.

Enhancements:

  • Establish dedicated CLI and library boundaries, including separate CLI and library MSRV policies and explicit backend installation semantics.
  • Add safe, atomic, idempotent project scaffolding and build-script integration requirements.
  • Expand the roadmap with dependency-ordered implementation slices covering CLI foundation, project integration, backend management, execution, reporting, migration, and retirement gates.

Documentation:

  • Add the comprehensive proposed cargo theorem CLI design document.
  • Index the new CLI design and document its application boundary in the developer guide.

Caution

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

  • Ignore

❌ Failed checks (1 error, 2 warnings)

Check name Status Explanation Resolution
Unit Architecture ❌ Error The design marks check read-only but allows check --compile to run Cargo and arbitrary build.rs; BackendProvider also combines lifecycle, execution, parsing, and replay. Move compilation behind an explicit command-side-effect boundary, or remove it from check; split BackendProvider into narrow lifecycle and execution/replay interfaces with explicit fallible dependencies.
Developer Documentation ⚠️ Warning Flag the omission: the PR adds CLI architecture, BackendProvider, MSRV, and build-helper requirements, but docs/developers-guide.md is unchanged. Update docs/developers-guide.md with the new crate boundaries, API responsibilities, MSRV split, backend boundary, and build-script integration; link the design document.
Concurrency And State ⚠️ Warning The design adds parallel runs, durable child processes, locks, ledger writes, and idempotency claims, but defines no lock/task ownership model and requires no interleaving or contention tests. Define lock scope, ordering, timeout, and atomic idempotency reservation; specify task cancellation, shutdown, and cleanup; add concurrent submission, lock-contention, cancellation, crash, and partial-failure tests.
✅ Passed checks (17 passed)
Check name Status Explanation
Docstring Coverage ✅ Passed No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (3 skipped: 3 unsupported.)
Linked Issues check ✅ Passed Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check ✅ Passed Check skipped because no linked issues were found for this pull request.
Testing (Overall) ✅ Passed The diff against origin/main changes only three Markdown files; no executable source, manifests, or test paths changed, and the design is explicitly marked “Status: proposed”.
User-Facing Documentation ✅ Passed The PR changes only Markdown; the CLI design is explicitly “Status: proposed”, and its implementation roadmap items remain unchecked, so no new behaviour requires users-guide documentation.
Module-Level Documentation ✅ Passed The PR diff contains only three Markdown files and no added or modified source modules; the module-level docstring check is therefore not applicable.
Testing (Unit And Behavioural) ✅ Passed Pass this check: the diff contains only three Markdown files; the CLI is marked proposed and roadmap test work remains unchecked, so no executable behaviour changed.
Testing (Property / Proof) ✅ Passed Keep this check passing: the PR changes Markdown only and explicitly recommends property tests for selectors, cursors, path containment, idempotent plans, and argument vectors.
Testing (Compile-Time / Ui) ✅ Passed Pass this check: the PR changes only Markdown, adds no Rust/TypeScript compile-time behaviour, and explicitly specifies focused snapshots for help, JSON, diagnostics, plans, and summaries.
Domain Architecture ✅ Passed The diff adds only Markdown; the design keeps CLI, project, runner, output, and backend adapters outside theoremc-core and states inward-only dependencies with injected command execution.
Observability ✅ Passed Pass this check: the PR changes only Markdown; it introduces no runtime operational behaviour, and the design still specifies tracing spans, bounded metrics, logs, run records, and diagnostics.
Security And Privacy ✅ Passed Pass: the diff contains only Markdown; it adds no secret-like literals and explicitly requires HTTPS, checksum checks, path containment, argument vectors, redaction, bounded logs, and safe hook bou...
Performance And Resource Use ✅ Passed Pass this check: the PR changes only Markdown; the design defines 50/500 pagination, bounded summaries and log excerpts, bounded parallelism and timeouts, and explicit pruning.
Architectural Complexity And Maintainability ✅ Passed Accept the documentation-only change: it isolates CLI dependencies, reuses build services, shares runner/report contracts for Kani and Verus, and states directed dependency boundaries and deferred...
Rust Compiler Lint Integrity ✅ Passed Pass this check: the complete PR range changes only three Markdown files; it adds no Rust paths, lint suppressions, artificial references, or clone operations.
Title check ✅ Passed The title accurately describes the main change: designing the Cargo-native cargo theorem CLI.
Description check ✅ Passed The description clearly explains the CLI design, documentation updates, roadmap changes, and key implementation decisions.

P2 Badge Reject stdout delivery in JSON mode

When an artefact-producing command is invoked with --json --deliver stdout, this delivery contract requires the report or generated source on stdout, while §8.2 requires stdout to contain exactly one JSON document and explicitly forbids mixing domain output with that document. Define this combination as invalid, or specify a JSON-safe interpretation of stdout, so implementations do not have to violate one of the two public contracts.

P2 Badge Require a theorem selector for multi-failure replay

A run may select many theorems and contain several failures, but replay <run-id> supplies no theorem or counterexample selector and this text does not define which failed theorem is chosen. In that common case the command cannot deterministically satisfy the stated one-run/theorem contract and could replay the wrong evidence; add an ID selector and require it when the source run has multiple replayable failures.

`cargo theorem create <theorem-id>` creates one valid `.theorem` document. It
accepts `--about`, `--backend`, `--tag`, `--path`, and `--template`. Without an
explicit path, it derives a normalized file name under `theorems/`.

P2 Badge Disambiguate the identifier accepted by create

The project defines a canonical external theorem ID as {normalized_path(P)}#{T} in docs/name-mangling-rules.md:157-167, and this CLI uses <theorem-id> for get and stable-ID selection, but create <theorem-id> also accepts an independent --path and otherwise derives a path. A caller passing the documented canonical form therefore provides the path twice, while a caller passing only T is not supplying the same kind of ID accepted by get; rename this argument to the theorem name or explicitly define how canonical IDs and --path interact.

Inline comments:
In `@docs/cargo-theorem-cli-design.md`:
- Line 352: Correct the capability-matrix wording for the create command from
“refuses overwrite” to “refuses to overwrite,” preserving the existing --force
option and table structure.
- Around line 415-416: Update the JSON envelope documentation to explicitly
define result as success-only and error as failure-only, ensuring the examples
consistently place command data and diagnostics according to that contract.
- Around line 381-388: Update the JSON-mode command semantics so --deliver
stdout is rejected as a usage error whenever --json is active, preserving stdout
for exactly one JSON document; document this invalid combination in the CLI
design and related delivery-option section.
- Around line 678-684: Update the canonical run-record command-capture and
persistence flow to redact sensitive values supplied through --backend-arg
before they are stored or logged. Extend the existing redaction mechanism near
environment values and configured secrets with typed secret arguments or
equivalent field-level redaction, covering the related command-argument metadata
and persistence paths while preserving non-sensitive arguments.
- Around line 527-530: Update the cargo theorem create path handling so explicit
--path values are canonicalized and verified to remain within the selected
workspace, including symlink resolution, before any file is written. Preserve
the existing default theorems/ containment and add a separately guarded escape
hatch only if external paths are intentionally supported.
- Around line 707-711: Update the replay &lt;run-id&gt; design so runs with
multiple failed theorems require an explicit theorem selector such as --id, or
fail with a bounded list of valid failed IDs; never choose an implicit first
failure. Preserve deterministic replay behavior for single-failure runs.
- Around line 129-151: Add a short caption to the Mermaid architecture diagram
and each package, command-capability, exit-code, and principle table in the
document, while preserving the existing description before the diagram and
leaving table contents unchanged.

In `@docs/roadmap.md`:
- Around line 549-553: Add Step 5.2 as a prerequisite for the alias-related work
in Step 5.0, ensuring canonical IDs, alias loading, cycle detection, and
resolution are defined before alias tests or execution depend on them;
alternatively defer alias coverage until Step 5.2 is complete.
- Around line 801-805: Update the roadmap acceptance wording to scope mandatory
code, arguments, and English fallback text to diagnostic objects only, while
localized text remains conditional on a configured localizer; avoid implying
that successful envelopes must contain undocumented diagnostic fields.
- Around line 311-316: Update the roadmap headings for Phase 3A and Steps 3A.1
through 3A.5 to use numeric dotted identifiers, and revise every dependency
reference to match the new identifiers. Preserve the existing heading titles and
roadmap structure.
