test(canonical): emit L0 summary and lock fixture failures

[shaun0927]

Summary

Follow-up repair for merged #1174 after ouroboros-agent[bot]'s latest substantive review found two remaining L0-a blockers:

1. the canonical harness did not emit the Meta SSOT slice: L0 — Canonical Test Harness for ooo auto acceptance #1170-required single copyable per-scenario summary line;
2. the schema loader's malformed-fixture rejection paths were behavior-defining but untested.

This PR keeps the #1157/#1170 minimal-substrate boundary intact: it does not wire live ouroboros_auto, does not add CI/replay/cost-budget machinery, and leaves live invocation deferred to L0-b.

What changed

• Adds format_canonical_summary_line() and a pytest_terminal_summary hook that prints one copyable line per discovered scenario, e.g.:

  CANONICAL cli-todo: shape_valid domain=cli completion=product_complete probes=headless_run,stdout_golden budget=1800s live=deferred_l0b
  

• Documents that summary line in tests/canonical/README.md.

• Adds focused tests for malformed fixture cases:

  • missing expected.yaml
  • empty goal.txt
  • YAML parse failure
  • non-mapping YAML root
  • missing required keys
  • invalid completion_mode

• Adds a formatter test pinning the copyable summary line.

Roadmap / design alignment

• Aligns with Meta SSOT slice: L0 — Canonical Test Harness for ooo auto acceptance #1170 acceptance criterion: "single human-readable summary line per scenario".
• Aligns with Meta SSOT: ooo auto Vision — Autonomous Completion Engine #1157 minimal-substrate self-audit by keeping L0-a hermetic and manual.
• Responds directly to feat(tests): canonical acceptance harness skeleton (L0-a) #1174's post-merge bot review without expanding into L0-b live-run scope.

Test plan

• uv run pytest tests/canonical/ -v → 13 passed, 1 skipped, with canonical summary line printed.
• uv run ruff check tests/canonical/ → clean.
• uv run ruff format --check tests/canonical/ → clean.
• uv run mypy tests/canonical/conftest.py tests/canonical/test_canonical.py tests/canonical/test_conftest.py → clean.

Merge-readiness rationale — follow-up to merged #1174

I re-audited merged #1174 against the #961 AgentOS roadmap SSOT, #1157 ooo auto minimal-substrate SSOT, and #1170 L0 canonical-harness design. Because #1174 was already merged and the latest substantive bot pass left two concrete post-merge blockers, I opened this repair PR rather than trying to mutate the merged PR.

What this PR fixes

The latest #1174 bot review identified two remaining issues:

1. Missing copyable per-scenario summary line required by Meta SSOT slice: L0 — Canonical Test Harness for ooo auto acceptance #1170.
2. Untested schema-loader failure paths for malformed canonical fixtures.

This PR addresses both directly:

• pytest_terminal_summary now emits a stable one-line status per scenario:

  CANONICAL cli-todo: shape_valid domain=cli completion=product_complete probes=headless_run,stdout_golden budget=1800s live=deferred_l0b
  

• tests/canonical/test_conftest.py now covers malformed fixture cases: missing expected.yaml, empty goal.txt, YAML parse failure, non-mapping YAML, missing required keys, and invalid completion_mode.

• The README documents the copyable line so maintainers know exactly what to paste into SSOT / PR progress comments.

Why this stays aligned with the SSOTs

• Meta SSOT slice: L0 — Canonical Test Harness for ooo auto acceptance #1170 L0 acceptance: the copyable per-scenario line is now implemented and tested.
• Meta SSOT: ooo auto Vision — Autonomous Completion Engine #1157 minimal-substrate direction: this does not add nightly CI, replay, budget tracking, refresh policy, divergence detection, or live LLM invocation.
• Meta SSOT: AgentOS roadmap sequencing (#920–#960) #961 sequencing: this remains a narrow Track-B-adjacent/test-harness follow-up outside Track C tier gates, and does not touch production orchestration / plugin / MCP surfaces.

Over-engineering check

This is intentionally small: one formatter, one pytest terminal-summary hook, one focused test module, and one README example. It does not introduce a custom reporter framework or premature live-run plumbing. The live=deferred_l0b marker is explicit so L0-a does not pretend PRODUCT_COMPLETE was exercised before L0-b wires live ouroboros_auto.

Verification

Local verification on 77a49d8:

• uv run pytest tests/canonical/ -v → 13 passed, 1 skipped, with the canonical summary line printed.
• uv run ruff check tests/canonical/ → clean.
• uv run ruff format --check tests/canonical/ → clean.
• uv run mypy tests/canonical/conftest.py tests/canonical/test_canonical.py tests/canonical/test_conftest.py → clean.

GitHub checks are also all green: Ruff Lint, MyPy, Python tests for 3.12/3.13/3.14, Bridge TypeScript, enforce-envelope, and enforce-boundary.

Bot / review status

ouroboros-agent[bot] has approved this PR with no blocking findings and no non-blocking suggestions. The PR is merge-clean with all required checks passing.

Scope Reviewed

• PR intent: Repair the post-merge feat(tests): canonical acceptance harness skeleton (L0-a) #1174 gaps by adding the Meta SSOT slice: L0 — Canonical Test Harness for ooo auto acceptance #1170-required copyable canonical scenario summary line and by testing malformed canonical fixture rejection paths.
• Main changed areas: tests/canonical/conftest.py, tests/canonical/test_conftest.py, and tests/canonical/README.md.
• Tests reviewed: canonical positive shape checks, new malformed-fixture loader tests, summary-line formatter test, and terminal summary output from uv run pytest tests/canonical/ -v.
• Checks considered: local pytest/ruff/mypy plus GitHub checks for Ruff Lint, MyPy, Python 3.12/3.13/3.14 tests, Bridge TypeScript, enforce-envelope, and enforce-boundary.

Blocking Issues

None.

Warnings

None.

Mutation-Test Thinking

• Likely mutants that should be killed:
  • Removing pytest_terminal_summary or changing the formatter output would be caught by test_format_canonical_summary_line_is_copyable and by manual pytest output inspection.
  • Removing required-key enforcement, completion-mode validation, YAML parse handling, non-mapping validation, empty-goal validation, or missing-file validation is now covered by focused negative-path tests.
  • Changing the live-run marker away from the L0-a deferred contract would fail the formatter pin.
• Mutants current tests may not catch:
  • Cosmetic changes to the separator title (canonical scenario summary) are not pinned. That is acceptable because the copyable scenario line itself is the contract.
  • Terminal rendering integration is indirectly covered by local pytest output rather than a pytester subprocess test. Given the hook is thin and the formatter is pinned, this is acceptable for the narrow repair.
• Additional tests recommended: none before merge. A pytester-level terminal-output test may be useful only if future L0-b live status branches make the reporter more complex.

Complexity / CRAP-style Risk

• High-risk functions/modules: none. The new formatter is pure string assembly; the terminal hook only loads discovered scenarios and writes one line per scenario.
• Complexity increase: minimal and test-local. No production path, MCP, orchestration, plugin, or EventStore code changed.
• Test coverage concern: none blocking. The exact loader branches flagged by the bot are now covered.
• Refactoring recommendation: none. A larger reporter abstraction would be over-engineering for one L0-a line.

Test Quality Assessment (6/7)

• Strong tests: the malformed-fixture tests directly exercise the behavior-defining pytest.fail branches; the formatter test pins the copyable status contract.
• Weak tests: terminal hook output is validated by local command evidence rather than a subprocess pytester assertion.
• Missing edge cases: none that should block this repair PR.
• Mocking concerns: none; no mocks were introduced.

Security / Operational Risk

None. The PR remains test/docs-only, uses the existing yaml.safe_load path, and introduces no network, subprocess, credential, or live LLM invocation behavior.

Looks Good

• Directly resolves both actionable feat(tests): canonical acceptance harness skeleton (L0-a) #1174 bot blockers.
• Preserves Meta SSOT: ooo auto Vision — Autonomous Completion Engine #1157/Meta SSOT slice: L0 — Canonical Test Harness for ooo auto acceptance #1170 minimal-substrate constraints: no CI/replay/budget/divergence/live-run expansion.
• Produces the SSOT-copyable per-scenario evidence line requested by Meta SSOT slice: L0 — Canonical Test Harness for ooo auto acceptance #1170.
• Adds negative-path tests for fixture rot without changing production code.
• Local and GitHub verification are green.
• ouroboros-agent[bot] has approved the PR with no blocking findings or suggestions.

Final Recommendation

APPROVE — ready to merge. The PR is narrow, evidence-backed, and fixes the merged #1174 gaps without introducing over-engineering or roadmap drift.

[shaun0927]

Final merge-readiness rationale — PR #1182 @ b1f61260

I rechecked this PR against the #961 AgentOS roadmap SSOT, the #1157 ooo auto minimal-substrate SSOT, and the #1170 L0 canonical-harness slice after the review-refresh commit.

What the PR does

PR #1182 is a narrow repair for the two concrete post-merge blockers left by the latest substantive #1174 review:

1. Meta SSOT slice: L0 — Canonical Test Harness for ooo auto acceptance #1170 required a single copyable per-scenario summary line, but feat(tests): canonical acceptance harness skeleton (L0-a) #1174 did not emit one.
2. The canonical scenario schema loader introduced behavior-defining malformed-fixture rejection paths, but feat(tests): canonical acceptance harness skeleton (L0-a) #1174 only covered the happy path.

This PR resolves those gaps by adding:

• format_canonical_summary_line() plus pytest_terminal_summary, which emits:

  CANONICAL cli-todo: shape_valid domain=cli completion=product_complete probes=headless_run,stdout_golden budget=1800s live=deferred_l0b
  

• focused malformed-fixture tests for missing expected.yaml, empty goal.txt, YAML parse failure, non-mapping YAML root, missing required keys, and invalid completion_mode.

• README documentation for the copyable summary line.

• an empty review-refresh commit (b1f61260) after local verification, because the bot's design-note environment reported a source/diff read failure rather than a code/design finding.

AgentOS / SSOT alignment

This remains aligned with #961 and the AgentOS direction because it is a test-harness repair for the Track B / ooo auto canonical acceptance lane, not a new AgentOS substrate surface. It does not touch production orchestration, plugin, MCP, EventStore, HITL, Workflow IR, or projection contracts.

It also stays inside #1157/#1170's minimal-substrate boundary:

• no nightly CI,
• no replay layer,
• no divergence metric,
• no cost-budget machinery,
• no refresh-rotation policy,
• no live ouroboros_auto invocation in L0-a.

The explicit live=deferred_l0b marker is important: the line is useful for SSOT progress comments while avoiding the false claim that PRODUCT_COMPLETE has already been exercised by this L0-a repair.

Over-engineering check

The implementation is intentionally small: one pure formatter, one thin pytest terminal-summary hook, one README example, and one focused negative-path test module. I do not see custom reporter infrastructure, premature live-run plumbing, or speculative AgentOS control-plane work.

Verification

Local verification on b1f61260:

• uv run pytest tests/canonical/ -v → 13 passed, 1 skipped, and the canonical summary line was printed.
• uv run pytest tests/canonical/ -v -k cli-todo → 5 passed, 1 skipped, 8 deselected, and the canonical summary line was printed.
• uv run ruff check tests/canonical/ → clean.
• uv run ruff format --check tests/canonical/ → clean.
• uv run mypy tests/canonical/conftest.py tests/canonical/test_canonical.py tests/canonical/test_conftest.py → clean.

GitHub status on current head b1f61260:

• Review decision: APPROVED.
• Merge state: CLEAN.
• Checks: Ruff Lint, MyPy, Python 3.12/3.13/3.14 tests, Bridge TypeScript, enforce-envelope, and enforce-boundary are all SUCCESS.
• ouroboros-agent[bot] shows APPROVE with no blocking findings and no non-blocking suggestions. Its Design Notes still mention an environment/source-snapshot read limitation, which I treat as an infra limitation rather than a PR design problem; the local diff inspection and checks above supply the missing evidence.

Verdict

Ready to merge. The PR directly closes the actionable #1174 follow-up gaps, keeps the #1170 L0-a boundary honest, and avoids over-engineering or AgentOS roadmap drift.

Mutation-Test Thinking

• Likely mutants that should be killed:
  • Removing or changing format_canonical_summary_line() output should fail test_format_canonical_summary_line_is_copyable.
  • Removing pytest_terminal_summary would not be caught by a subprocess-level pytester assertion, but the pure formatter is pinned and the local terminal output was manually verified.
  • Removing required-key, invalid completion-mode, YAML parse, non-mapping YAML, missing-file, or empty-goal validation should fail the focused negative-path tests in test_conftest.py.
  • Changing the L0-a live=deferred_l0b marker should fail the formatter test, preventing this repair from overclaiming live ouroboros_auto execution.
• Mutants current tests may not catch:
  • Cosmetic changes to the terminal separator title (canonical scenario summary) are not pinned. This is acceptable because the stable copyable line is the behavior contract.
  • A regression where the pytest terminal hook is never called would be best caught by a future pytester subprocess test if the reporter grows beyond this thin hook.
• Additional tests recommended: none before merge. A pytester-level terminal-output integration test can be deferred until L0-b if live status branches make the reporter more complex.

Complexity / CRAP-style Risk

• High-risk functions/modules: none. The changed code is test-harness-only and does not touch production orchestration, MCP, plugin, EventStore, HITL, Workflow IR, or projection paths.
• Complexity increase: minimal. One pure string formatter and one thin pytest terminal hook are proportional to the Meta SSOT slice: L0 — Canonical Test Harness for ooo auto acceptance #1170 summary-line acceptance criterion.
• Test coverage concern: none blocking. The exact malformed-fixture paths flagged by the substantive feat(tests): canonical acceptance harness skeleton (L0-a) #1174 bot review are now covered.
• Refactoring recommendation: none. Introducing a custom reporter abstraction would be over-engineering for one L0-a status line.

Test Quality Assessment (6/7)

• Strong tests:
  • test_format_canonical_summary_line_is_copyable pins the SSOT-copyable evidence contract.
  • malformed-fixture tests directly exercise behavior-defining pytest.fail branches for fixture rot.
  • existing scenario shape tests continue to pin the canonical fixture surface.
• Weak tests:
  • terminal hook integration is verified by local command output rather than a pytester subprocess assertion.
• Missing edge cases:
  • no blocking missing cases for this repair PR; terminal-output subprocess coverage can wait until L0-b if the reporter becomes stateful.
• Mocking concerns: none; no mocks were introduced.

Security / Operational Risk

None. This is a test/docs-only repair. It introduces no network calls, subprocess execution, credential handling, live LLM invocation, filesystem mutation outside pytest fixture loading, or production runtime behavior. YAML parsing remains on the existing yaml.safe_load path.

Looks Good

• Directly resolves both actionable feat(tests): canonical acceptance harness skeleton (L0-a) #1174 post-merge blockers.
• Preserves the Meta SSOT: ooo auto Vision — Autonomous Completion Engine #1157/Meta SSOT slice: L0 — Canonical Test Harness for ooo auto acceptance #1170 minimal-substrate boundary: no nightly CI, replay layer, cost budget, divergence metric, refresh policy, or live ouroboros_auto wiring.
• Keeps the AgentOS Meta SSOT: AgentOS roadmap sequencing (#920–#960) #961 sequencing clean by staying in the narrow Track B / canonical-harness repair lane rather than creating a new substrate surface.
• The live=deferred_l0b marker prevents maintainers from mistaking L0-a shape validation for completed live PRODUCT_COMPLETE exercise.
• Local verification is green: pytest tests/canonical/, pytest tests/canonical/ -k cli-todo, Ruff check, Ruff format check, and mypy all passed.
• GitHub checks are green and the PR is merge-clean.
• ouroboros-agent[bot] is in APPROVE state with no blocking findings or suggestions; its remaining Design Notes limitation is environmental/source-snapshot access, not a code or architecture defect.

Final Recommendation

APPROVE — ready to merge. PR #1182 is a narrow, evidence-backed repair that makes the canonical harness evidence copyable and locks the loader failure contract without over-engineering or drifting from the AgentOS SSOT direction.

Independent merge-readiness rationale — PR #1182

I re-reviewed this PR against the #961 AgentOS SSOT, #1157 minimal-substrate direction, and #1170 L0 canonical-harness contract. I ignored bot verdicts and checked the implementation and tests directly.

What this PR does:

• Repairs the L0-a canonical harness slice by emitting a stable, copyable one-line summary for each discovered canonical scenario.
• Locks fixture-shape failures so malformed canonical scenarios fail as test failures instead of silently rotting.
• Documents that live ouroboros_auto execution remains explicitly deferred to L0-b.
• Adds one follow-up commit (c75aa2b8) to directly test the pytest terminal-summary hook, not just the pure formatter, so the manual PR/SSOT evidence line cannot disappear unnoticed.

Why this is aligned with #961 and not over-engineered:

• It stays in the minimal L0-a lane: pytest fixture validation, manual summary evidence, and documentation only.
• It does not introduce schedulers, nightly CI, replay infrastructure, custom reporters, budgets enforcement, or live LLM execution.
• The added hook test is deliberately small and local; it proves the actual manual-reporting contract without building new framework machinery.

Independent checks I ran locally:

• uv run pytest tests/canonical/ -v → 14 passed, 1 skipped.
• uv run pytest tests/canonical/ -v -k cli-todo → 5 passed, 1 skipped, 9 deselected.
• uv run ruff check tests/canonical/ → passed.
• uv run ruff format --check tests/canonical/ → passed.
• uv run mypy tests/canonical/conftest.py tests/canonical/test_canonical.py tests/canonical/test_conftest.py → passed.

Merge recommendation: after the direct terminal-summary hook regression test, this PR is mergeable as the correct minimal repair for the canonical harness L0-a slice.

PR Review Summary

Verdict

Approve

Scope Reviewed

• PR intent: Repair the canonical L0-a harness from feat(tests): canonical acceptance harness skeleton (L0-a) #1174 by adding copyable per-scenario summary output and locking malformed fixture failures.
• Main changed areas: tests/canonical/conftest.py, tests/canonical/test_conftest.py, and tests/canonical/README.md.
• Tests reviewed: fixture loading failure modes, canonical summary formatting, and the new direct pytest_terminal_summary hook regression test.
• Checks considered: local canonical pytest runs, ruff, ruff format check, mypy, and current GitHub check status for the pushed head.

Blocking Issues

None.

Warnings

None.

Mutation-Test Thinking

• Likely mutants that should be killed: removing required-key validation, allowing invalid completion_mode, removing the summary line, changing probe/budget rendering, or deleting the terminal-summary hook.
• Mutants current tests may not catch: no merge-blocking survivor remains after adding the direct terminal hook test; formatter-only coverage would not have caught hook removal, but c75aa2b8 closes that gap.
• Additional tests recommended: none required before merge. L0-b live execution should add separate tests when the actual ouroboros_auto path lands.

Complexity / CRAP-style Risk

• High-risk functions/modules: none. The changed code is test harness infrastructure, not production runtime logic.
• Complexity increase: Low. The implementation uses existing pytest hooks and simple fixture validation.
• Test coverage concern: Low after the hook-level regression test.
• Refactoring recommendation: None before merge; avoid custom reporter abstractions unless future scenarios prove they are needed.

Test Quality Assessment (6/7)

• Strong tests: Negative fixture-shape tests, exact copyable summary-line assertion, and direct terminal-summary hook coverage.
• Weak tests: No live ouroboros_auto path is exercised, intentionally, because that remains L0-b scope.
• Missing edge cases: No merge-blocking edge case found for L0-a.
• Mocking concerns: The hook test uses a small fake terminal reporter; this is appropriate because the behavior under review is the emitted separator and line, not pytest internals.

Security / Operational Risk

None. This PR only touches tests/docs and does not alter runtime execution, permissions, secrets, network calls, or production state.

Looks Good

• Preserves the minimal-substrate direction from Meta SSOT: AgentOS roadmap sequencing (#920–#960) #961/Meta SSOT: ooo auto Vision — Autonomous Completion Engine #1157.
• Produces a stable manual evidence line for PR/SSOT comments.
• Fails closed on malformed canonical fixtures.
• Keeps live execution explicitly opt-in/deferred rather than smuggling it into L0-a.

Final Recommendation

Approve and merge. The PR now has direct evidence for the manual summary contract, adequate malformed-fixture coverage, low complexity, and no runtime/security risk.

• CI artifact shows Bridge TypeScript, MyPy, Ruff, Python 3.12/3.13/3.14 tests, enforce-boundary, and enforce-envelope all passed.
• Live ouroboros_auto execution remains intentionally skipped at tests/canonical/test_canonical.py:124 for L0-a/L0-b scope separation.

Design / Roadmap Gate

Affected-boundary review covered scenario discovery, fixture loading, pytest parametrization, terminal-summary reporting, documentation, and the deferred live-run surface. The reporter boundary now has test evidence, malformed fixture paths fail as test failures through _load_scenario, and the live state-machine/persistence/replay boundary remains explicitly out of scope for L0-a rather than partially wired. No current-HEAD blocker found in the audited boundary.
