fix(orchestrator): credit transcript test commands for tests_passed claims

[nkjunbc]

Problem

In fat-harness mode (the default since the legacy execution mode was removed), the atomic AC verifier rejects legitimate, green work as FABRICATION_SUSPECTED, failing the whole AC even though the code is written and the tests pass.

Observed in production (Windows, Claude Code runtime): every sub-AC reported success ([AC_COMPLETE: N], full suite green) yet parallel_executor.ac.completed logged success=False, cascading to dependency_failed skips and a failed session. The recorded verdict:

typed_evidence_present: True
typed_evidence_valid:   True
verifier_ran:           True
verifier_passed:        False
verifier_failure_class: FABRICATION_SUSPECTED
verifier_reasons: unsupported evidence claims:
  commands_run: python -m ruff check src/poc/structure_extractor.py ...;
  tests_passed: tests/test_structure_and_draft_substance.py::test_numbering_system_classifies_roman_and_arabic; ...

Root cause

_verify_atomic_evidence_against_runtime_messages builds backed_commands only from commands_run evidence entries, and _runtime_messages_support_test_claim uses that list as the sole source of candidate test commands.

So a tests_passed node-id claim can only be verified if the corresponding pytest invocation was also echoed into commands_run. When the agent ran pytest <file> (clearly present in the runtime transcript, with a passing result) but listed only a lint command in commands_run, there is no candidate test command, so every node-id claim is marked unsupported → FABRICATION_SUSPECTED → the AC fails on correct work.

The transcript is the ground truth here, but the verifier never consults the Bash messages' own commands for test-claim support.

Fix

_runtime_messages_support_test_claim now also treats each Bash message's own recorded command (_runtime_message_command_values) as a candidate test command, in addition to the backed commands_run entries.

That command is backed by definition — it is the literal invocation recorded in the transcript — so a real, transcript-proven test run can support a node-id tests_passed claim even when the agent did not duplicate it into commands_run.

Anti-fabrication is preserved. A claim is still credited only when:

• the command is a real Bash invocation in the transcript (_runtime_message_supports_command_claim),
• the chunk shows test success (_message_contains_test_success), and
• the claim is targeted by the command (_test_command_targets_claim).

The two existing "rejects … missing from runtime" tests still reject.

Tests

• Added test_fat_harness_verifier_accepts_pytest_node_id_claim_backed_by_transcript_command, which reproduces the bug: lint in commands_run, pytest <file> only in the transcript, node-id tests_passed claim. It fails on main (verifier rejects) and passes with this change.
• Existing fat-harness accept/reject tests in tests/unit/orchestrator/test_parallel_executor.py continue to pass.

Note: 3 pre-existing failures in this file (*_normalizes_workspace_absolute_file_claim, *_rejects_unscoped_file_and_failed_test_command, *_accepts_wrapped_broad_pytest_for_current_test_file) are unrelated Windows-only test-fixture issues: they embed tmp_path directly into a JSON evidence literal, and on Windows the backslash path separators are invalid JSON escapes (Evidence is not valid JSON: Invalid \escape), so the evidence fails to parse before any verifier logic runs. They pass on POSIX CI (forward-slash paths) and fail identically on unmodified main; this change does not touch them.

Context

Relates to #1164 (implementer subtype=success rejected by the executor, then cascades dependency_failed). This PR addresses one root cause of that rejection in the verifier's matching logic. Companion: #1168 covers the sibling commands_run redirection/pipe matching gap. The two are independent and can land in either order.

Thanks @nkjunbc — approving. This lands cleanly as a narrow Track A / #978 verifier follow-up, outside Track C tier gates (same lineage as #1006 / #1018 / #1020 / #1026).

I traced the verifier path end-to-end before approving. A few notes for the record, since this touches anti-fabrication semantics:

Why this is safe. Adding _runtime_message_command_values(message) to the candidate set means _runtime_message_supports_command_claim(candidate, message) is tautologically satisfied for per-message candidates (the candidate is drawn from the same message it is checked against). That gate is effectively a no-op here. The actual anti-fabrication protection now rests on two downstream invariants:

1. _message_contains_test_success consults _runtime_message_test_proof_text, which extracts only from structured runtime fields (output / stdout / tool_result) — never from assistant narration or content. An agent cannot inject a fake success marker into those fields; they are populated by the tool runtime itself.
2. For node-id claims, _test_command_targets_claim requires the file part of the node id to appear in the chunk, anchored to the recorded command. For summary-style claims, _claim_summary_matches_runtime_chunk requires the summary text to appear in the structured proof text. I confirmed test_fat_harness_verifier_rejects_shell_wrapped_unittest_summary_missing_from_runtime and test_fat_harness_verifier_rejects_unittest_summary_missing_from_runtime still reject under this code path for exactly that reason.

Also confirmed: _runtime_message_command_values reads from tool_input / input / arguments containers and never from output or content, so the new candidate source is structurally trustworthy.

Two small follow-ups (non-blocking, fine in a separate PR):

• The 9-line comment is helpful for the why, but it would be worth one extra line noting that the first gate is tautological for per-message candidates and that the security guarantee is carried by the success + targeting gates. Right now a future reader could mistake it for three independent checks.
• A negative test for the new code path would round out coverage: a Bash message whose tool_input.command is a non-test command (e.g., echo "test_foo.py::test_bar passed" or a cat of a fake summary) — the _looks_like_test_command filter should reject it, and an explicit test would lock that invariant in.

One housekeeping ask before I merge: could you link a CI run on unmodified main showing the three test failures you flagged (*_normalizes_workspace_absolute_file_claim, *_rejects_unscoped_file_and_failed_test_command, *_accepts_wrapped_broad_pytest_for_current_test_file)? Your description says they fail identically on main and are unrelated Windows path-resolution issues — I'd like that on the record so we can split them into a separate needs-info issue rather than letting them stay implicit in the test file.

Thanks again for the careful root-cause writeup — the production transcript with verifier_failure_class: FABRICATION_SUSPECTED despite [AC_COMPLETE] made the bug very easy to confirm.

[nkjunbc]

Thanks @shaun0927 — both follow-ups are in e6911da:

• Comment clarification. Expanded the _runtime_messages_support_test_claim comment to spell out that the per-message _runtime_message_supports_command_claim gate is tautological (the candidate is that message's own command) and that the anti-fabrication guarantee is carried by _message_contains_test_success + _test_command_targets_claim, not three independent checks — matches your trace.
• Negative test. test_fat_harness_verifier_rejects_node_id_claim_backed_only_by_non_test_command: a Bash message running cat fake_results.txt whose recorded output is literally test_slugify.py::test_spaces passed must not back the node-id claim — _looks_like_test_command excludes it and it stays FABRICATION_SUSPECTED. (Used cat instead of echo "...::... passed" to avoid unescaped quotes in the JSON evidence literal; same intent, and it also proves a fake marker in the output alone isn't enough.)

On the housekeeping ask — plus a correction to my own PR text. There's no CI run on main showing those three failures, because they don't fail on CI. When I dug in, my original "Windows path-resolution" wording turned out to be wrong. The real cause is a test-fixture portability bug: the three tests embed tmp_path directly into a JSON evidence literal, e.g.

f'{{"files_touched":["{touched_file}"], ...}}'

On Windows tmp_path is C:\Users\...\test_todo.py, so the backslashes are invalid JSON escapes and the evidence never parses — it fails before any verifier logic runs:

typed_evidence_error = 'Evidence is not valid JSON: Invalid \escape (line 1, col 22)'

On POSIX the paths are forward-slash, the JSON is valid, and the tests pass — which is exactly why this PR's Linux CI is green (Test 3.12/3.13/3.14 ✓). Local Windows run on unmodified main (git checkout main, clean tree):

FAILED tests/unit/orchestrator/test_parallel_executor.py::TestParallelACExecutor::test_fat_harness_verifier_normalizes_workspace_absolute_file_claim
FAILED tests/unit/orchestrator/test_parallel_executor.py::TestParallelACExecutor::test_fat_harness_verifier_rejects_unscoped_file_and_failed_test_command
FAILED tests/unit/orchestrator/test_parallel_executor.py::TestParallelACExecutor::test_fat_harness_verifier_accepts_wrapped_broad_pytest_for_current_test_file
3 failed, 186 deselected
# all three fail with: Evidence is not valid JSON: Invalid \escape

I've corrected the PR description to reflect this. The fix for those tests is to encode the path in the fixtures (json.dumps(str(path)) or Path.as_posix()) rather than f-string interpolation. Happy to open a separate needs-info issue with this writeup if that's the preferred home for it — just say the word.

What Improved

• Added transcript-command candidates for tests_passed verification while keeping command extraction structured and limited to Bash message data.
• Added positive regression coverage for transcript-backed pytest node-id claims and negative coverage for non-test commands with fake success output.

Issue #1164 Requirements

Requirement	Status
Legitimate green work should not be rejected as FABRICATION_SUSPECTED solely because the pytest command appears in the runtime transcript but not in commands_run.	MET — src/ouroboros/orchestrator/parallel_executor.py:1290 adds the Bash message command as a candidate, and tests/unit/orchestrator/test_parallel_executor.py:5011 verifies the regression case.
Preserve anti-fabrication behavior for unsupported/fake test claims.	MET — _looks_like_test_command and runtime proof/targeting gates remain in place at src/ouroboros/orchestrator/parallel_executor.py:1291, and tests/unit/orchestrator/test_parallel_executor.py:5116 verifies a fake cat output remains rejected.
Emit more diagnostic visibility for verifier rejection and inferred dependency cascades from issue #1164.	NOT MET / OUT OF PR SCOPE — the PR body explicitly frames this as one root-cause verifier fix related to #1164, not the full logging/dependency-visibility work.

Test Coverage

The newly added verifier path in src/ouroboros/orchestrator/parallel_executor.py:1290 is covered by tests/unit/orchestrator/test_parallel_executor.py:5011 for the intended transcript-backed pytest case and tests/unit/orchestrator/test_parallel_executor.py:5116 for the non-test-command rejection guard. Existing surrounding rejection tests remain adjacent at tests/unit/orchestrator/test_parallel_executor.py:4928 and tests/unit/orchestrator/test_parallel_executor.py:5194. All newly added logic/state mutations have corresponding focused tests. I attempted to run the targeted pytest selection, but the local build failed because the repository git wrapper times out during hatch-vcs version detection.

Design / Roadmap Gate

design_context.md frames this as a Track A / #978 evidence-gated verifier hardening change, outside broader Track C tier gates. Current HEAD aligns with that scope: command candidates are still extracted from structured runtime fields at src/ouroboros/orchestrator/parallel_executor.py:536, and the new candidate path remains guarded by test-command recognition plus runtime proof/claim targeting at src/ouroboros/orchestrator/parallel_executor.py:1291.

Merge Recommendation

• Ready to merge as the narrow verifier root-cause fix; keep the broader #1164 logging/dependency-visibility work tracked separately.

Merge-readiness re-audit — reviewer pass from a separate worktree

Re-audited this PR end-to-end from an isolated worktree (/tmp/ouro-pr1166 at head e6911da) against the Issue #961 Meta SSOT, the ooo auto / ooo run direction, and an over-engineering lens. Posting the reasoning so the audit trail is self-contained.

1. SSOT alignment (Issue #961)

This PR is explicitly named in the Track A row of the SSOT body and re-confirmed in five freshness syncs on 2026-05-22 (warden 11:20 / 13:06 / 15:56 / 20:27 / 20:59 KST):

"#1166 and #1168 are open, green, and APPROVED as fat-harness verifier evidence follow-ups."

It sits in the same #978 / #920 fat-harness verifier lineage as the already-merged hardening series #1006 / #1018 / #1020 / #1026 / #1068 / #1069 / #1072 / #1073, outside Track C tier gates. There is no roadmap drift.

2. Direction check vs. ooo auto / ooo run

The bug is the upstream root cause of a real ooo auto failure mode documented in #1164: every sub-AC reports [AC_COMPLETE] and subtype=success, but the verifier records verifier_passed=False / verifier_failure_class=FABRICATION_SUSPECTED, which cascades into dependency_failed skips and fails the session. That directly blocks the Track B "self-healing ooo auto" narrative. Fixing it here is on-strategy, not a tangent.

3. Over-engineering check — surgical, not over-engineered

Production-code delta is literally one effective line of logic:

candidate_commands = (*backed_commands, *_runtime_message_command_values(message))
# ...
for candidate in candidate_commands  # was: for candidate in backed_commands

Everything else in the +202/-1 diff is:

• +16 lines of comment spelling out the anti-fabrication contract (added at owner's explicit request in review).
• +2 tests — one positive regression (the actual production transcript shape) and one negative guard (cat fake_results.txt whose output literally contains test_x.py::test_y passed is still rejected because _looks_like_test_command filters it out).

No new types, no new abstractions, no new public API, no helper added — the change reuses six pre-existing helpers (_runtime_message_command_values, _looks_like_test_command, _runtime_message_supports_command_claim, _message_contains_test_success, _test_command_targets_claim, _runtime_message_test_proof_text). This is the minimum-blast-radius shape this fix can take.

4. Anti-fabrication invariants — preserved

Re-traced the gates after the change:

1. Candidate source is structural, not prose. _runtime_message_command_values reads only from tool_input / input / arguments / args containers (lines 545–553 of parallel_executor.py), never from output or assistant content. Adapters populate these; the agent cannot inject into them.
2. Test-command filter still in force. _looks_like_test_command (line 903) gates every candidate — proven by the new negative test.
3. Success marker is structural, not prose. _message_contains_test_success → _runtime_message_test_proof_text only consults structured runtime fields (result_preview / output / stdout / stderr), never content.
4. Targeting still anchored. _test_command_targets_claim requires the node-id file part to appear in the recorded command + proof text.

The two existing FABRICATION_SUSPECTED reject tests (*_rejects_shell_wrapped_unittest_summary_missing_from_runtime, *_rejects_unittest_summary_missing_from_runtime) plus the new negative guard all still reject — verified locally:

tests/unit/orchestrator/test_parallel_executor.py
  test_fat_harness_verifier_accepts_pytest_node_id_claim_backed_by_transcript_command   PASSED
  test_fat_harness_verifier_rejects_node_id_claim_backed_only_by_non_test_command       PASSED
  test_fat_harness_verifier_rejects_shell_wrapped_unittest_summary_missing_from_runtime PASSED
  test_fat_harness_verifier_rejects_unittest_summary_missing_from_runtime               PASSED
4 passed, 187 deselected in 0.77s

(Run on e6911da against local src/ on PYTHONPATH to bypass the globally-installed ouroboros shim.)

5. Review-cycle state

• Owner @shaun0927 approved on 2026-05-22 02:07 KST with an end-to-end trace.
• Both non-blocking follow-ups he asked for landed in e6911da (comment clarification + negative test).
• The author also corrected their own PR description: the three pre-existing test failures are not "Windows path-resolution" but a JSON-escape portability bug from f-string-interpolating tmp_path into a JSON evidence literal; root-cause is on record in-thread.
• CI: 9/9 green (Lint Ruff/MyPy/Bridge-TS, Tests 3.12/3.13/3.14, enforce-envelope, enforce-boundary).
• mergeable: MERGEABLE, mergeStateStatus: CLEAN, reviewDecision: APPROVED.

Verdict

Merge-ready as-is. No fix commits added by this audit — the diff is already at the right scope, the anti-fabrication contract is preserved, the SSOT explicitly lists this PR as a clean Track A follow-up, and every concern raised in the original review thread has been addressed in e6911da. A separate /pr-review skill pass with full mutation-survivor / CRAP-risk analysis is being posted next.

Verdict

Approve

Scope Reviewed

• PR intent: Fix fat-harness atomic-AC verifier so a transcript-proven pytest <file> run can back a node-id tests_passed claim even when the agent did not duplicate the exact pytest invocation into commands_run evidence. Without this, legitimate green ACs are stamped FABRICATION_SUSPECTED and cascade dependency_failed.
• Main changed areas:
  • src/ouroboros/orchestrator/parallel_executor.py — _runtime_messages_support_test_claim (one-line candidate-set expansion + 16-line anti-fabrication contract comment).
  • tests/unit/orchestrator/test_parallel_executor.py — one positive regression test (*_accepts_pytest_node_id_claim_backed_by_transcript_command) + one negative guard test (*_rejects_node_id_claim_backed_only_by_non_test_command).
• Tests reviewed:
  • New positive: agent puts ruff in commands_run, runs pytest test_slugify.py -q only in transcript → claim accepted (was rejected on main).
  • New negative guard: agent puts cat fake_results.txt in commands_run, recorded output literally contains test_slugify.py::test_spaces passed → claim still rejected via _looks_like_test_command.
  • Existing reject tests preserved: *_rejects_shell_wrapped_unittest_summary_missing_from_runtime, *_rejects_unittest_summary_missing_from_runtime.
  • Local pytest run on e6911da (with PYTHONPATH=src to bypass the globally-installed shim): 4 passed, 187 deselected in 0.77s.
• Checks considered: GitHub status checks 9/9 SUCCESS (Lint Ruff/MyPy/Bridge-TS, Tests 3.12/3.13/3.14, enforce-envelope, enforce-boundary); mergeStateStatus CLEAN; reviewDecision APPROVED; head commit e6911da already addresses owner's two follow-ups.

Blocking Issues

None.

Warnings

None.

Mutation-Test Thinking

• Likely mutants that should be killed:
  • Drop _runtime_message_command_values(message) from the candidate union → positive test fails (regression coverage proven).
  • Drop _looks_like_test_command(candidate) filter → negative guard test fails (cat fake_results.txt would back the claim through its fake output marker).
  • Replace tuple(candidate for candidate in candidate_commands if ...) with (backed_commands[0],) style narrowing → positive test fails (claim becomes unsupported again).
  • Make _runtime_message_supports_command_claim skip the message-self check → no functional regression in the current test surface (this gate is tautological for per-message candidates, as both owner trace and the in-code comment document), so this mutant is intentionally uncovered — the in-code comment now explicitly explains why that is by design.
• Mutants current tests may not catch:
  • Loosening _message_contains_test_success to read from assistant content instead of structured runtime fields. This would silently weaken anti-fabrication but is out of this PR's scope — the helper isn't touched. needs verification whether a standalone test asserts the structural-only read.
  • Loosening _test_command_targets_claim to drop the file-part anchor. Same comment — outside this diff; covered indirectly by the two preserved reject tests, but no targeted single-mutant test exists.
• Additional tests recommended: None as a merge blocker. The two helpers above are pre-existing and untouched by this PR; harvesting targeted mutant-killing tests for them belongs in a separate #978 verifier-hardening follow-up alongside Scope runtime command evidence to validation commands #1068/Normalize workspace file evidence claims #1069/Harden docs-only evidence prompts #1072/Respect docs-only evidence scope #1073, not here.

Complexity / CRAP-style Risk

• High-risk functions/modules: _runtime_messages_support_test_claim is on a security-relevant path (anti-fabrication). Cyclomatic complexity is unchanged by this PR: still one outer for + one inner generator + three guard checks; the diff only widens the iterable feeding the generator.
• Complexity increase: Zero net complexity added. One identifier (candidate_commands) introduced; one assignment line; one renamed variable in the comprehension. Branch count, nesting depth, and side-effect surface are identical.
• Test coverage concern: None for the changed surface — both the new acceptance path and the new candidate source's failure mode (non-test command) are exercised by the two new tests, and the prior reject tests remain green.
• Refactoring recommendation: None. The 16-line contract comment is the right shape for this kind of fix — the change in the candidate set is one line, but the semantic change is "this gate is now tautological for per-message candidates; the security guarantee shifts to the downstream success+targeting gates," which is exactly what the comment captures. Removing or shortening the comment would be a regression.

Test Quality Assessment (6/7)

• Strong tests:
  • The positive regression mirrors the actual production transcript shape (lint in commands_run, pytest only in tool_input.command, node-id claim) — not a synthetic minimal repro.
  • The negative guard is deliberately adversarial: cat fake_results.txt whose output literally contains test_slugify.py::test_spaces passed. This proves the new candidate source does not open a fake-marker-in-output attack vector, because the filter is on the command, not the output.
  • Both tests assert at the event level (execution.ac.typed_evidence.observed → verifier_passed / verifier_failure_class), which is the contract surface, not internal state.
• Weak tests: None in this PR's surface.
• Missing edge cases: None blocking. Possible future hardening (out of scope): a Goose-style argv list form for tool_input.command, e.g. ["python", "-m", "pytest", "test_x.py"]; this is already covered by _runtime_command_value_to_text (line 557) and the _test_command_invocation shell-wrapper path (line 908), but a single explicit Goose-shape test would be a tidy addition in a follow-up.
• Mocking concerns: Tests use _FinalMessageRuntime + _make_replaying_event_store — same shape as every other fat-harness verifier test in the file. No new mock layers introduced.

Security / Operational Risk

• Anti-fabrication contract (security-equivalent for this codebase): preserved end-to-end after re-tracing:
  1. _runtime_message_command_values extracts only from tool_input / input / arguments / args structured containers (lines 545–553) — never from agent narration or content. The runtime adapter populates these, not the LLM.
  2. _looks_like_test_command filter still gates every candidate (verified by the new negative guard).
  3. _message_contains_test_success → _runtime_message_test_proof_text reads only result_preview / output / stdout / stderr structured fields (lines 895–899).
  4. _test_command_targets_claim still anchors the node-id file part to the recorded command + proof text.
• Operational risk: None. The change can only widen the set of legitimate transcripts the verifier accepts; it cannot make the verifier accept any transcript the prior gates would have accepted, because the candidate added is gated by the same _looks_like_test_command filter and the same downstream success/targeting gates.
• Backward compatibility / migration: None. Pure in-process verifier logic; no schema, no DB, no on-disk format, no event-stream contract changes.
• Logging / secrets: No changes.

Looks Good

• Diff is the minimum-blast-radius shape this fix can take — one-line logic change, zero new types/abstractions/helpers.
• Anti-fabrication contract is documented in the code itself, not just in PR text, so the rationale survives the PR being closed.
• Negative guard test is genuinely adversarial (fake marker in output) and locks the new candidate source's safety invariant in.
• Author corrected their own PR description after deeper investigation (Windows path-resolution → JSON-escape portability bug from f-string tmp_path interpolation) — good intellectual honesty on the side issue.
• SSOT (Issue Meta SSOT: AgentOS roadmap sequencing (#920–#960) #961) explicitly names this PR as a clean Track A fat-harness verifier follow-up across five 2026-05-22 freshness syncs, same lineage as Require verifier PASS for fat-harness AC acceptance #1006/fix(harness): accept zero-failure verifier summaries #1018/fix(harness): reject standalone failed verifier output #1020/fix(orchestrator): align atomic verifier with Codex runtime evidence #1026/Scope runtime command evidence to validation commands #1068/Normalize workspace file evidence claims #1069/Harden docs-only evidence prompts #1072/Respect docs-only evidence scope #1073.

Final Recommendation

Approve and merge. This is a surgical, well-tested, on-strategy fix for a production-observed verifier bug. The diff is the minimum shape it can take, the anti-fabrication contract is preserved and now documented in-code, the two added tests target both the bug and the new attack vector the bug-fix could have opened, all 9 CI checks are green, mergeStateStatus is CLEAN, and the owner has already approved with both review follow-ups addressed in e6911da. No blocking issues, no warnings, no merge-time risk identified.

No substantive prior blocker; previous bot review reported no blocking findings and noted it could not inspect files/diff.	WITHDRAWN — there was no current-HEAD-verified blocker to maintain; this review inspected the changed files and adjacent verifier helpers directly.

Test Coverage

The newly added verifier logic has corresponding tests: tests/unit/orchestrator/test_parallel_executor.py:5011 covers accepting a node-id tests_passed claim backed by the transcript pytest command, and tests/unit/orchestrator/test_parallel_executor.py:5116 covers rejecting a fake success marker from a non-test command. Existing adjacent reject coverage remains around tests/unit/orchestrator/test_parallel_executor.py:5193. I could not run the targeted tests locally because pytest is absent from the base interpreter and uv run failed during editable-package version detection due a hanging git wrapper, but the current code and test coverage were inspected directly.

Design / Roadmap Gate

design_context.md identifies this PR as a Track A fat-harness verifier evidence follow-up in the #978/#920 lineage and outside Track C tier gates. Current HEAD evidence matches that scope: the only production change is the verifier candidate source in src/ouroboros/orchestrator/parallel_executor.py:1290, with no schema, persistence, CLI/MCP, or public API change.

Merge Recommendation

• Merge is reasonable as-is; no current-HEAD blocker was verified.
