test(auto): assert runtime probe metadata shape

[Q00]

Summary

• Adds direct MCP metadata coverage for the runtime_probe_evidence shape introduced by fix: resolve post-merge review blocker foundations #1205.
• Pins probe kind, pass status, summary, duration, and payload serialization so clients can rely on the public result contract.

Changes

• Covers _result_meta with a RuntimeEvidence fixture in tests/unit/auto/test_surface.py.

Notes

Follow-up for the non-blocking review item on #1205.

Test Coverage Notes

• Reviewed the added test at tests/unit/auto/test_surface.py:499, _result_meta serialization at src/ouroboros/mcp/tools/auto_handler.py:1305, AutoPipelineResult.runtime_probe_evidence at src/ouroboros/auto/pipeline.py:258, and RuntimeEvidence shape at src/ouroboros/orchestrator/runtime_evidence.py:60.
• Attempted to run pytest -q tests/unit/auto/test_surface.py::test_result_meta_serializes_runtime_probe_evidence_shape; pytest is not installed in this environment (python3 -m pytest also reports no module named pytest).

Design Notes

This is test-only and matches the existing public metadata contract: _result_meta emits runtime_probe_evidence as a list of primitive dictionaries.

Design / Roadmap Gate

Affected boundary is MCP auto result metadata. The changed test exercises the direct _result_meta contract and aligns with AutoPipelineResult.runtime_probe_evidence and RuntimeEvidence fields. No persistence, replay, runtime execution, or compatibility behavior is changed by this PR.

Directional Notes

Maintainer memory emphasized runtime reality over optimistic docs, so review focused on whether the added test pins the actual MCP result surface rather than a stale or internal-only shape. No blocker was found.

Test Coverage

• Reviewed the added test at tests/unit/auto/test_surface.py:499, _result_meta serialization at src/ouroboros/mcp/tools/auto_handler.py:1305, AutoPipelineResult.runtime_probe_evidence at src/ouroboros/auto/pipeline.py:258, and RuntimeEvidence shape at src/ouroboros/orchestrator/runtime_evidence.py:60.
• Attempted to run pytest -q tests/unit/auto/test_surface.py::test_result_meta_serializes_runtime_probe_evidence_shape; pytest is not installed in this environment (python3 -m pytest also reports no module named pytest).

Merge Recommendation

Approve. The PR is test-only, the asserted shape matches current HEAD implementation, and no blocking regressions were identified. Test execution could not be completed because pytest is unavailable in the review environment.

Test Coverage Notes

• Reviewed added coverage in tests/unit/auto/test_surface.py:499, _result_meta serialization in src/ouroboros/mcp/tools/auto_handler.py:1196 and :1305, AutoPipelineResult.runtime_probe_evidence in src/ouroboros/auto/pipeline.py:258, probe persistence/result paths in src/ouroboros/auto/pipeline.py:1580 and :2887, and RuntimeEvidence.to_dict() in src/ouroboros/orchestrator/runtime_evidence.py:102.
• Attempted python3 -m pytest -q tests/unit/auto/test_surface.py::test_result_meta_serializes_runtime_probe_evidence_shape; execution was unavailable because pytest is not installed. uv is also unavailable.

Design Notes

This is a narrow test-only change pinning an existing MCP result metadata contract. It does not alter runtime, persistence, replay, or orchestration behavior.

Design / Roadmap Gate

Affected boundary is the MCP auto result metadata surface. Runtime evidence is produced and persisted via RuntimeEvidence.to_dict(), rehydrated through RuntimeEvidence.from_dict(), carried on AutoPipelineResult, and exposed by _result_meta. The added test covers the final serialization boundary with populated evidence; no compatibility or replay behavior changes are introduced.

Directional Notes

Maintainer memory emphasized runtime reality over optimistic surfaces, so review focused on whether the test pins the actual MCP metadata emitted from current AutoPipelineResult and RuntimeEvidence objects. No blocker was found from current source evidence.

Test Coverage

• Reviewed added coverage in tests/unit/auto/test_surface.py:499, _result_meta serialization in src/ouroboros/mcp/tools/auto_handler.py:1196 and :1305, AutoPipelineResult.runtime_probe_evidence in src/ouroboros/auto/pipeline.py:258, probe persistence/result paths in src/ouroboros/auto/pipeline.py:1580 and :2887, and RuntimeEvidence.to_dict() in src/ouroboros/orchestrator/runtime_evidence.py:102.
• Attempted python3 -m pytest -q tests/unit/auto/test_surface.py::test_result_meta_serializes_runtime_probe_evidence_shape; execution was unavailable because pytest is not installed. uv is also unavailable.

Merge Recommendation

Approve. The added test matches the current HEAD contract and no blocking regression was identified. Test execution could not be completed in this environment due to missing pytest tooling.

Merge-readiness rationale (English)

This PR is a focused, test-only follow-up to the merged #1205 runtime-probe-evidence work, and it is ready to merge.

What it does

Adds a single regression test, test_result_meta_serializes_runtime_probe_evidence_shape, that pins the MCP _result_meta serialization for a populated RuntimeEvidence tuple. The asserted shape is the public contract that MCP clients consume:

runtime_probe_evidence: list[{
    probe_kind, passed, summary, duration_seconds, payload
}]

The test exercises the real _result_meta(AutoPipelineResult(...)) path with a concrete RuntimeEvidence instance, so it covers the actual handler boundary in src/ouroboros/mcp/tools/auto_handler.py:1305 rather than a stub.

Why it aligns with the SSOT direction

• Track B (ooo auto self-healing) in issue Meta SSOT: AgentOS roadmap sequencing (#920–#960) #961 lists this as part of the #1222–#1228 follow-up cluster: "post-merge/adjacent fixes rather than new Meta SSOT: AgentOS roadmap sequencing (#920–#960) #961 substrate proposals".
• The fix: resolve post-merge review blocker foundations #1205 review left a non-blocking suggestion to pin the MCP metadata shape; this PR is the smallest possible response to that suggestion.

Why it is not over-engineered

• 1 file changed, +33/-0. No runtime, persistence, or contract change.
• Reuses the existing RuntimeEvidence fixture types and the production _result_meta symbol.

Why it is mergeable

• reviewDecision: APPROVED (two consecutive ouroboros-agent approve verdicts on ff4e1fc and 48a1ae6 — current HEAD).
• Latest review: APPROVE with no blockers, no follow-up findings, no non-blocking suggestions, clean Design / Roadmap Gate notes.
• All 8 required checks green (Ruff, MyPy, Bridge TS, enforce-envelope, enforce-boundary, Tests 3.12/3.13/3.14).
• mergeStateStatus: CLEAN, mergeable: MERGEABLE.
• The test asserts the current implementation shape and would break if RuntimeEvidence.to_dict() (at src/ouroboros/orchestrator/runtime_evidence.py:102) silently changed its emitted keys.

Recommending merge.

PR Review Summary

Posted via /oh-my-claudecode:pr-review skill — evidence-backed verdict.

Verdict

Approve

Scope Reviewed

• PR intent: pin the MCP _result_meta serialization for AutoPipelineResult.runtime_probe_evidence to the documented runtime_probe_evidence: list[{probe_kind, passed, summary, duration_seconds, payload}] shape so MCP clients can rely on the public contract.
• Main changed areas: tests/unit/auto/test_surface.py (+33/-0) — one new test, two new imports.
• Tests reviewed: the new test plus the production _result_meta callsite (src/ouroboros/mcp/tools/auto_handler.py:1196 and :1305), AutoPipelineResult.runtime_probe_evidence (src/ouroboros/auto/pipeline.py:258), RuntimeEvidence.to_dict() (src/ouroboros/orchestrator/runtime_evidence.py:102).
• Checks considered: Ruff Lint, MyPy, Bridge TypeScript, enforce-envelope, enforce-boundary, Tests Python 3.12 / 3.13 / 3.14, two consecutive ouroboros-agent APPROVE verdicts.

Blocking Issues

None.

Warnings

None.

Mutation-Test Thinking

• Likely mutants the test would kill:
  • Removing any of the five keys (probe_kind, passed, summary, duration_seconds, payload) from RuntimeEvidence.to_dict() — the assert meta["runtime_probe_evidence"] == [...] equality is exhaustive.
  • Renaming a key (e.g., probe_kind → kind) — killed by the same equality.
  • Wrapping in an outer object instead of a list — killed.
  • Returning None or [] when evidence is populated — killed.
  • Coercing duration_seconds to a string — killed because Python == distinguishes 0.01 from "0.01".
• Mutants the test may not catch:
  • A subtle drift where evidence is silently truncated to N items when there are more than one (the test uses a tuple of length 1). Low risk — RuntimeEvidence serialization is per-item and the surrounding production code already iterates over the tuple.
  • Field-ordering changes (the assertion uses dict equality, which is order-independent). Acceptable since JSON serialization downstream is also order-independent.
• Additional tests recommended: none for merge gating. Optional: a parametrized two-evidence case to pin list semantics, but fix: resolve post-merge review blocker foundations #1205 already covers the multi-item persistence path; this PR is intentionally about the metadata-emit boundary only.

Complexity / CRAP-style Risk

• High-risk functions/modules: none changed in production code. Test is straight-line with one assertion.
• Complexity increase: zero in production; +1 test function.
• Test coverage concern: this PR strictly increases coverage at a thin public boundary that previously had no direct shape assertion. The bot review confirmed prior coverage was indirect.
• Refactoring recommendation: none.

Test Quality Assessment

• Strong tests: the assertion is on exact dict equality of the emitted metadata, which is far more discriminating than a "key in meta" or isinstance check. It uses a real RuntimeEvidence instance and the production _result_meta callable, not a stub.
• Weak tests: none observed.
• Missing edge cases: empty-tuple case (runtime_probe_evidence=()) is not asserted here — but that is the default-construction path and is already implicitly covered elsewhere by tests that don't pass evidence.
• Mocking concerns: none — no patching.

Security / Operational Risk

• Auth/authz: untouched.
• Data: test-only, no production data path changes.
• Persistence: untouched.
• Replay: untouched.
• Failure mode: if the asserted shape ever drifts, this test fails loudly — exactly the intended signal.
• Observability: untouched.

Looks Good

• One file, one test, one new symbol import. Smallest possible PR for the goal.
• Two consecutive bot APPROVE verdicts on the same content with empty blocker / follow-up / non-blocking tables.
• Aligns with issue Meta SSOT: AgentOS roadmap sequencing (#920–#960) #961 Track B's pattern of narrow post-merge follow-ups.
• All CI green; clean against main.

Final Recommendation

APPROVE. A test-only PR that pins an externally visible MCP contract. No blocking findings, no warnings, no operational risk. Merge.
