fix(orchestrator): credit transcript test commands for tests_passed claims#1166
Conversation
…laims The fat-harness atomic verifier sourced candidate test commands only from `commands_run` evidence. When an agent ran `pytest <file>` (recorded in the runtime transcript) but listed only a lint command in `commands_run`, every node-id `tests_passed` claim was rejected as FABRICATION_SUSPECTED even though the test run is real and green — failing the entire AC on correct work. `_runtime_messages_support_test_claim` now also treats each Bash message's own recorded command as a candidate, in addition to the backed `commands_run` entries. That command is backed by definition (it is the literal transcript invocation), so a transcript-proven test run can support a node-id claim. Anti-fabrication is preserved: the command must still be a real Bash invocation in the transcript, the chunk must show test success, and the claim must be targeted by the command (`_test_command_targets_claim`). The two existing "rejects ... missing from runtime" tests still reject. Adds a regression test that fails without this change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

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

…-command guard Addresses review follow-ups on Q00#1166: - Expand the comment in `_runtime_messages_support_test_claim` to note the per-message `_runtime_message_supports_command_claim` gate is tautological (the candidate is that message's own command); the anti-fabrication guarantee is carried by the test-success and claim-targeting gates, not by three independent checks. - Add `test_fat_harness_verifier_rejects_node_id_claim_backed_only_by_non_test_command`: a Bash message running a non-test command (`cat fake_results.txt`) whose output literally contains `<node-id> passed` must NOT back a node-id `tests_passed` claim — `_looks_like_test_command` excludes it and the claim stays FABRICATION_SUSPECTED.

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.

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.

Problem
In fat-harness mode (the default since the
legacyexecution mode was removed), the atomic AC verifier rejects legitimate, green work asFABRICATION_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) yetparallel_executor.ac.completedloggedsuccess=False, cascading todependency_failedskips and a failed session. The recorded verdict:Root cause
_verify_atomic_evidence_against_runtime_messagesbuildsbacked_commandsonly fromcommands_runevidence entries, and_runtime_messages_support_test_claimuses that list as the sole source of candidate test commands.So a
tests_passednode-id claim can only be verified if the correspondingpytestinvocation was also echoed intocommands_run. When the agent ranpytest <file>(clearly present in the runtime transcript, with a passing result) but listed only a lint command incommands_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_claimnow also treats each Bash message's own recorded command (_runtime_message_command_values) as a candidate test command, in addition to the backedcommands_runentries.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_passedclaim even when the agent did not duplicate it intocommands_run.Anti-fabrication is preserved. A claim is still credited only when:
_runtime_message_supports_command_claim),_message_contains_test_success), and_test_command_targets_claim).The two existing "rejects … missing from runtime" tests still reject.
Tests
test_fat_harness_verifier_accepts_pytest_node_id_claim_backed_by_transcript_command, which reproduces the bug: lint incommands_run,pytest <file>only in the transcript, node-idtests_passedclaim. It fails onmain(verifier rejects) and passes with this change.tests/unit/orchestrator/test_parallel_executor.pycontinue to pass.Context
Relates to #1164 (implementer
subtype=successrejected by the executor, then cascadesdependency_failed). This PR addresses one root cause of that rejection in the verifier's matching logic. Companion: #1168 covers the siblingcommands_runredirection/pipe matching gap. The two are independent and can land in either order.
