Summary

This branch refactors shared-action invocation scanning so its workflow-path
and action-use filtering responsibilities are cohesive helpers, preserving
the existing workflow-contract behaviour while removing nested conditionals.
It now also directly proves the new helper contracts and keeps their private
documentation concise.

Full details: Testing (Overall)

Explanation

PASS. The pull request only refactors tests/workflow_contracts/shared_actions_test.py; it adds no product functionality or intended behaviour change. The diff preserves the previous workflow suffix filtering and shared-action prefix filtering exactly. The existing contract tests still scan the real .github/workflows files and assert approved shared-action paths, full-SHA pinning, and one consistent revision. These assertions provide a meaningful oracle and are not vacuous.

Full details: User-Facing Documentation

Explanation

Pass the check. The diff changes only tests/workflow_contracts/shared_actions_test.py. _workflow_paths preserves sorted workflow selection and suffix filtering. _shared_action_use preserves the existing uses type and prefix checks. The refactor does not change user-facing functionality or behaviour, so docs/users-guide.md does not require an update.

Full details: Developer Documentation

Explanation

PASS. The pull request changes only the private, test-local implementation in tests/workflow_contracts/shared_actions_test.py. It adds _workflow_paths and _shared_action_use, both documented with docstrings, and does not change a production API, architectural boundary, tooling requirement, roadmap item, execplan, ADR, or design document. The existing docs/developers-guide.md already documents the workflow contract tests, their PyYAML scanning, command, and shared-action validation. No developer-guide or design-document update is required for this local refactor.

Full details: Module-Level Documentation

Explanation

Pass the module-level documentation check. tests/workflow_contracts/shared_actions_test.py starts with a module docstring that states its purpose: contract-testing shared-action invocations across workflows. It states its utility by naming make test-workflow-contracts. It also states the module's relationship to workflow files through its scope across every workflow. The docstring exists in both the PR revision and origin/main, so the pull request does not introduce a documentation failure.

Full details: Testing (Unit And Behavioural)

Explanation

The refactor adds two helper implementations but adds no tests for their local behaviour. _workflow_paths now owns suffix filtering and deterministic ordering, and _shared_action_use now owns shared-action, unrelated, missing, and non-string filtering. The only test functions still call _shared_action_versions; no test calls either new helper directly. The real .github/workflows directory contains only supported .yml files, so the tests do not exercise the skip or ordering cases. The current workflow scan does check valid shared-action references and the common-version invariant, but it does not cover the new helper edge cases or error paths. The change does not alter production workflows, so an end-to-end test is not required.

Resolution

Add focused unit tests for _workflow_paths using temporary entries with both supported and unsupported suffixes and assert deterministic order. Add parameterized tests for _shared_action_use covering a valid shared-action string, an unrelated string, a missing uses key, and a non-string value. Add scanner tests for non-mapping YAML and no shared-action invocations, while retaining the existing real-workflow contract tests.

Full details: Testing (Property / Proof)

Explanation

Pass the check. The pull request only extracts existing behaviour from tests/workflow_contracts/shared_actions_test.py. The base revision already sorted workflow paths and applied the same uses type and prefix filter. The new helpers preserve those operations, and the existing recursive traversal and assertions remain unchanged. Therefore, the pull request introduces no new invariant over inputs, orderings, states, or transitions that requires property tests or a formal proof.

Full details: Testing (Compile-Time / Ui)

Explanation

Pass this check. The diff changes only tests/workflow_contracts/shared_actions_test.py, a Python workflow-contract test. It adds no Rust or TypeScript compile-time behaviour, so no trybuild or language-equivalent test applies. It also adds no text, structured, multi-variant, or UI-adjacent output surface; the helpers return internal workflow paths and action references for assertions. Snapshot tests are therefore not appropriate or required.

Full details: Unit Architecture

Explanation

Refactor _workflow_paths so it performs WORKFLOWS_DIR.iterdir() behind an Iterator[Path] query API. The new helper has no explicit input for the filesystem and no declared or handled OSError path, so the caller now hides fallible directory I/O behind an apparently pure read. The diff moves this operation out of _shared_action_invocations and therefore makes fallibility and the filesystem dependency less visible. The remaining YAML read is also fallible, but this pull request specifically introduces the new hidden query boundary.

Resolution

Make path selection pure and injectable. Pass an iterable of directory entries into _workflow_paths, and perform WORKFLOWS_DIR.iterdir() at the test boundary where its OSError can be converted into a clear contract-test failure. Alternatively, give the helper an explicit directory dependency and catch and report filesystem errors at that boundary. Add a focused test for the error path and retain the existing deterministic suffix filtering.

Full details: Domain Architecture

Explanation

PASS. The diff changes only tests/workflow_contracts/shared_actions_test.py. _workflow_paths and _shared_action_use remain test helpers that read workflow files and inspect parsed YAML mappings. They do not modify domain code or introduce domain dependencies on adapter, transport, persistence, framework, or infrastructure details. The custom check has no applicable failure condition.

Full details: Observability

Explanation

PASS. The exact diff from origin/main changes one file only: tests/workflow_contracts/shared_actions_test.py. It extracts deterministic workflow-path and shared-action filtering helpers, while retaining YAML validation and invocation assertions. It adds no production operational behaviour, logging, metrics, tracing, or alerts. The observability check does not apply.

Full details: Security And Privacy

Explanation

Pass the Security and Privacy check. The pull request changes only tests/workflow_contracts/shared_actions_test.py. The diff extracts _workflow_paths and _shared_action_use; both preserve the previous filtering behaviour. yaml.safe_load, recursive mapping traversal, immutable SHA validation, assertions, and invocation ordering remain in place. The changed lines add no secrets, credentials, tokens, permissions, network access, unsafe sinks, or sensitive-data output. Existing workflow secret references are unchanged and contain no secret values.

Full details: Performance And Resource Use

Explanation

PASS. The diff only extracts existing operations. _workflow_paths() keeps the same single sorted iterdir() scan and suffix filter. _shared_action_use() keeps the same one uses lookup and prefix check per traversed mapping. YAML reads, recursive traversal, result appends, and validation remain unchanged. The change adds no loop, I/O call, clone, cache, retry, or unbounded collection. The checked-in input is seven workflow files totalling 10,879 bytes, and the new helpers do not change the linear traversal or memory behaviour.

Full details: Concurrency And State

Explanation

Treat this check as satisfied. The diff changes only tests/workflow_contracts/shared_actions_test.py and only extracts synchronous helpers. It adds no async execution, tasks, cancellation, locks, queues, transactions, parallelism, or shared mutable state. It retains sorted workflow traversal and list-based result collection; no interleaving-sensitive behaviour is introduced.

Full details: Architectural Complexity And Maintainability

Explanation

Approve the change. The committed diff modifies only tests/workflow_contracts/shared_actions_test.py and adds no dependency or module edge. _workflow_paths owns workflow suffix filtering and ordering. _shared_action_use owns the existing shared-action predicate. Both helpers have narrow names, explicit contracts, and one immediate caller. They remove branching from _shared_action_invocations without adding a framework, registry, layer, global state, or speculative reuse mechanism. Existing recursive traversal, YAML validation, ordering, and version checks remain in the same test module.

Full details: Rust Compiler Lint Integrity

Explanation

Pass the check. The pull request changes only tests/workflow_contracts/shared_actions_test.py; git diff origin/main...HEAD -- '*.rs' returns no Rust paths and no added Rust lint suppressions or clone() calls. The Rust compiler lint integrity conditions are therefore not applicable.

Treat the current GitHub check status as green. All reported PR checks now pass.

Mark Testing (Unit And Behavioural) as resolved. The PR now includes focused tests for both helpers:

  • test_workflow_paths_filter_supported_suffixes_in_order tests supported suffix filtering and lexical ordering.
  • test_shared_action_use_filters_workflow_mappings tests a valid shared-action string, a missing uses value, and a non-string uses value.

Keep Unit Architecture open. _workflow_paths still calls WORKFLOWS_DIR.iterdir() internally at Line 25. It has no injectable directory-entry input. It also does not convert OSError into a clear workflow-contract failure.

Keep this work in the PR. It is in scope for code safety and validation coverage. Do not create a GitHub issue. No related open issue exists.

Use this AI-agent prompt:

Update `tests/workflow_contracts/shared_actions_test.py` to resolve the remaining Unit Architecture failure.

Requirements:
1. Make `_workflow_paths` a pure and injectable query helper.
   - Change it to accept an `Iterable[Path]` or `Iterator[Path]` of directory entries.
   - Preserve the current filtering rule: accept only `.yaml` and `.yml` suffixes.
   - Preserve deterministic lexical ordering of returned paths.
   - Do not access `WORKFLOWS_DIR` inside `_workflow_paths`.

2. Move `WORKFLOWS_DIR.iterdir()` into `_shared_action_invocations`, which is the workflow-contract test boundary.
   - Catch `OSError` from `WORKFLOWS_DIR.iterdir()`.
   - Fail with a clear assertion message that identifies the workflow directory and states that its entries could not be read.
   - Pass the resulting directory entries into `_workflow_paths`.

3. Update the existing `_workflow_paths` unit test.
   - Do not monkeypatch `WORKFLOWS_DIR`.
   - Create temporary `.yaml`, `.yml`, and unsupported-suffix files.
   - Pass `tmp_path.iterdir()` directly to `_workflow_paths`.
   - Assert that only supported workflow paths are returned in lexical order.

4. Add focused coverage for the `OSError` boundary behaviour.
   - Monkeypatch the directory iteration performed by `_shared_action_invocations` so it raises `OSError`.
   - Assert that the test fails with the new clear contract-test message.

5. Preserve existing YAML loading, recursive mapping traversal, invocation ordering, version validation, and workflow-contract assertions.
6. Run the focused workflow-contract tests and the repository formatter, linter, type checker, and full test suite.
