Summary

This branch preserves ADR-008's accepted decision and records the retirement
of EnvLock as a dated addendum rather than restoring its synchronization
tests. Environment-variable callers use injected mockable::Env seams, while
current-working-directory callers use the existing working-directory seam or
an absolute-path/-C route. Migrations #491, #492, and #493 are recorded as
complete; issue #494 tracks removal.

Closes #321.

Roadmap task: (3.11.5)

Review walkthrough

Validation

  • make check-fmt: passed.
  • make lint: passed, including Whitaker.
  • make doc-coverage: passed (98.98%).
  • make test: passed (2,398 nextest tests and doctests).
  • make markdownlint: passed.
  • make nixie: passed.

Notes

No execplan was required; the branch implements the issue's specified decision
record and documentation work without changing EnvLock behaviour or tests.

References

Summary by Sourcery

Retire EnvLock as the long-term synchronization strategy and document the migration path to injected environment and path-based working-directory seams.

Enhancements:

  • Document EnvLock as a retiring legacy exception and direct environment-variable callers to injected seams, while directing CWD callers to existing seam or path-based alternatives.

Documentation:

  • Record the accepted EnvLock retirement decision, migration status, and planned removal in the ADR and roadmap; update developer and test-support guidance accordingly.

Merge Risk: ⚪ Minimal · up to 369eb

This change retires EnvLock guidance without changing runtime behavior or tests; the remaining issues are limited to minor documentation clarity and wording, so no actionable merge-blocking risk remains.

Full details: Out of Scope Changes check

Explanation

The changes remain within scope. They update the required ADR, developer guidance, test policy, legacy module notices, crate documentation, and roadmap without changing EnvLock behaviour or adding unrelated code.

Full details: Docstring Coverage

Explanation

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 2 files. (3 skipped: 3 unsupported.)

Full details: Testing (Overall)

Explanation

PASS — The pull request introduces no product functionality or behavioural change. The cumulative diff from the inferred base changes only documentation and Rust module comments; it adds no test files, test markers, executable declarations, or test configuration. test_support/src/env_lock.rs keeps its implementation and existing tests unchanged. The testing requirement is therefore not applicable.

Full details: User-Facing Documentation

Explanation

Mark this check as passed. The PR changes only internal guidance, ADR/roadmap content, and Rust module documentation. It does not change user-facing functionality or behaviour. test_support is unpublished, and no source implementation changes are present. Therefore, no update to docs/users-guide.md or a migration guide is required.

Full details: Developer Documentation

Explanation

Accept the documentation check. The PR changes only documentation and module comments; no new API or build requirement is introduced. docs/developers-guide.md documents the retiring EnvLock seam, injected mockable::Env usage, CWD alternatives, and the prohibition on new callers or tests. docs/adr-008-environment-seam-taxonomy.md preserves the accepted status, original date, and decision text, then records retirement in a dated addendum. Roadmap item 3.11.5 remains open because issue #494 still tracks removal; completed migration subtasks #491–#493 are checked. No new execplan or translated developer-guide copy is present, and the changed internal links resolve.

Full details: Module-Level Documentation

Explanation

The changed Rust modules carry module-level //! documentation. In particular, test_support/src/env_lock.rs:1-11 explains the seam's purpose, its thread-bound re-entrant locking utility, its legacy status, replacement seams, and relationship to ADR-008 and issue #494. test_support/src/lib.rs:1-17 identifies the crate's test-support role and the retained env_lock component. Other surviving touched modules also retain documented headers, including src/runner/process/mod.rs and src/status_timing_tests.rs. No changed module lacks the required documentation.

Full details: Testing (Unit And Behavioural)

Explanation

Pass this check. The PR changes documentation only: the Rust diff modifies module-level documentation in test_support/src/env_lock.rs and test_support/src/lib.rs, with no executable-code additions or test changes. Existing EnvLock tests remain unchanged. The PR retires the seam and does not change an externally observable workflow, so no new unit, behavioural, or end-to-end test is required by this check.

Full details: Testing (Property / Proof)

Explanation

Pass this check. The pull request changes documentation and module comments only. The executable Rust content and existing EnvLock tests, including the existing proptest, are unchanged from the base revision. The pull request introduces no new behaviour, invariant, lemma, or proof assumption that requires property testing or exhaustive proof.

Full details: Testing (Compile-Time / Ui)

Explanation

Mark this check PASS. The diff from the merge-base to HEAD changes only six documentation or documentation-comment files. The only Rust changes are module-level documentation in test_support/src/env_lock.rs and test_support/src/lib.rs; no declarations, implementation, tests, UI cases, snapshots, or runtime output changed. Therefore no compile-time behaviour exists that requires a trybuild test, and snapshot testing is not appropriate for these developer and API documentation edits.

Full details: Unit Architecture

Explanation

Pass. The pull-request diff from the apparent base changes only documentation and Rust module documentation. It adds no query or command logic, no fallible API, dependency, side-effect, state mutation, or test. The new guidance makes the legacy EnvLock boundary explicit, forbids new callers and tests, and directs callers to injected mockable::Env or explicit CWD seams. Existing EnvLock implementation and callers remain unchanged, so no Unit Architecture failure is introduced.

Full details: Domain Architecture

Explanation

Pass Domain Architecture. The complete diff against main changes documentation and Rust module documentation only. It adds no domain logic, public declarations, adapter calls, transport or persistence dependencies. The guidance reinforces injected mockable::Env seams and keeps EnvLock in test_support as a retiring infrastructure seam.

Full details: Observability

Explanation

Treat this check as passed. The pull request changes only documentation and Rust module-level documentation. The diff adds no executable behaviour, operational failure mode, metric path, trace boundary, alert condition, or log decision point. No observability changes are required.

Full details: Security And Privacy

Explanation

Pass the Security and Privacy check. The PR diff against main changes guidance, ADR/roadmap text, and Rust documentation comments only; it does not change executable behaviour, authentication, authorization, permissions, parsing, or data flows. test_support/src/env_lock.rs keeps its implementation and tests unchanged. Added text contains no secrets, credentials, tokens, keys, certificates, customer data, or operational data. The environment-variable references document existing seams and child-process isolation without adding secret values or logging paths.

Full details: Performance And Resource Use

Explanation

Mark this check PASS. The complete PR range from 1d0cb16 to HEAD changes only AGENTS.md, Markdown documents, and Rust module documentation. The EnvLock implementation and tests remain unchanged. The diff adds no loops, collections, allocations, cloning, I/O, retries, polling, or blocking work. No performance or resource-use failure condition is introduced.

Full details: Concurrency And State

Explanation

Pass this check. The pull request changes only AGENTS.md and documentation, plus Rust module-level documentation in test_support/src/env_lock.rs and test_support/src/lib.rs; it introduces no shared mutable state, lock, task, ordering, or cancellation behaviour. The existing EnvLock implementation remains unchanged and already documents thread binding, re-entrancy, and mutex ownership. Existing tests cover nested and out-of-order release, contention, interleaved operations, and mutex-poison recovery. Existing CwdGuard tests cover CWD restoration. The new guidance explicitly prohibits new EnvLock callers and tests and directs migration to injected or isolated seams.

Full details: Architectural Complexity And Maintainability

Explanation

Pass this check. The complete PR diff changes six documentation or documentation-comment files only; it adds no dependency, trait, layer, registry, framework, generated path, or runtime orchestration. The existing EnvLock callers and the existing mockable::Env seam are unchanged between the base commit and HEAD. The PR documents retirement and directs migration to existing seams, so it introduces no architectural complexity that matches a failure condition.

Full details: Rust Compiler Lint Integrity

Explanation

Accept this change for Rust Compiler Lint Integrity. The PR diff against origin/main changes only documentation comments in test_support/src/env_lock.rs and test_support/src/lib.rs; it adds no Rust code, lint suppression, artificial usage anchor, or .clone() call. The existing EnvLock implementation, tests, module boundary, and callers are unchanged. The repository contains no explicit broad dead_code, unused_imports, or unused allowances in Rust source.

@coderabbitai Addressed the remaining Developer Documentation and Module-Level Documentation checks in 369eb0d. ADR-008 now preserves the merge-base Accepted. metadata, 2026-08-06 date, and original main decision text; the retirement is a dated 2026-08-26 addendum. The existing module documentation states that EnvLock is a thread-bound, re-entrant global lock for legacy process-global environment/CWD tests and prevents interference. The roadmap separately marks closed migrations #491-#493 complete and leaves #494 open. All declared deterministic gates pass.

@leynos Address the documentation findings.

docs/adr-008-environment-seam-taxonomy.md retains Accepted. and the 2026-08-06 date. It records the retirement decision in the dated 2026-08-26 addendum. The addendum includes the required replacement seams, CWD routes, issue references, and prohibitions.

test_support/src/env_lock.rs now states the module purpose. It identifies EnvLock as a thread-bound, re-entrant global lock for legacy process-global environment and CWD mutations. It also states that the lock prevents interference.

The roadmap marks #491, #492, and #493 complete. It leaves removal under #494 open.

The current title includes roadmap item 3.11.5. It meets the title-check requirement.

The focused merge-base diff could not run because the base SHA was unavailable in the local clone. Direct inspection of the current files verified the requested documentation content. I did not independently run the declared validation gates in this sandbox.

or -C/--directory. Keep issue `#494` explicitly dependent on removing all
remaining EnvLock callers.

In `@test_support/src/env_lock.rs`:
- Around line 7-9: Update the documentation comment near the injected
mockable::Env reference to list the CWD options as three alternatives: the
existing working-directory seam, absolute paths, or -C/--directory. Preserve the
surrounding wording and content.

Record that EnvLock is a retiring exception, not a synchronization mechanism to
harden. Direct remaining callers to injected mockable::Env seams before removal
under #494.
Direct developers away from adding EnvLock callers or tests while preserving the
legacy CWD ordering guidance until tracked migrations remove the seam.
Record the injected mockable::Env replacement and sequence the caller
migrations before the tracked removal of the legacy seam.
leynos added 3 commits August 28, 2026 12:54
Distinguish environment-variable injection from working-directory migration
so the retirement record directs the remaining CWD callers to a viable seam.
Keep the ADR amendment metadata, describe the legacy guard's utility, and
make the roadmap migration work independently trackable.
Preserve ADR-008's accepted decision and metadata while recording the
retirement as its dated addendum. Mark the completed migration issues in the
roadmap separately so only the outstanding retirement work remains open.
State the production, test, and CWD migration completion criteria in the
roadmap, and make #494 contingent on removing every remaining legacy caller.
Clarify the matching CWD alternatives at the module boundary.

⚠️ Action not completed

Head commit changed.

Note: CodeRabbit is an incremental review system and does not re-review already reviewed commits. This command is applicable only when automatic reviews are paused.

Keep the current `main` tool-installation and Whitaker guidance after the
rebase while retaining the EnvLock retirement instructions. The entity merge
otherwise duplicated and then partially displaced that unrelated content.

@leynos Mark all three checks as resolved.

  • Module-Level Documentation: Resolved. test_support/src/env_lock.rs states the module purpose. It identifies EnvLock as a thread-bound, re-entrant global lock for legacy tests that mutate process-global environment or CWD state. It states that the lock prevents interference.
  • Developer Documentation: Resolved. ADR-008 retains its merge-base Accepted. status, 2026-08-06 date, and original primary decision text. The only ADR change is the dated ### 2026-08-26: EnvLock retirement addendum. The addendum documents the required environment and CWD seams, issues #491–Retire EnvLock and the env mutation guards from test_support #494, and the prohibition on new callers and synchronization tests.
  • Title check: Resolved. The current title includes roadmap item 3.11.5.

Do not create a follow-up issue. No further work is required for these checks, so no AI agent prompt is needed.
