Fix ledger provenance test to allow in-flight PRs

[zendev-author]

Closes #292

Achieved outcome

The test test_no_row_that_names_a_merged_pull_request_lacks_its_commit now correctly distinguishes merged pull requests (which must have their merge commit recorded) from open/unmerged pull requests (which may legitimately have blank MERGE_COMMIT per AUTHOR_RUNBOOK.md section 7).

Tested revision

d2fa44b - Fix: Ledger provenance test to allow in-flight PRs with blank MERGE_COMMIT

Changed artifacts

• scripts/tests/test_backfill_merge_commits.py — Modified test_no_row_that_names_a_merged_pull_request_lacks_its_commit to query GitHub merge status before validating provenance. Open PRs may have blank MERGE_COMMIT; merged PRs must not.

Acceptance criteria

• 1. A PR following AUTHOR_RUNBOOK.md section 7 can pass the test before merge — tested via this PR and PR REQ-CONFIG-003 debt repair: MarketId validation and RecipeDefinition bounds #288
• 2. A merged PR without commit is still rejected — test logic validates only merged PRs
• 3. Test name and implementation agree about "merged" — now checks state == "MERGED" via GitHub API
• 4. PR REQ-CONFIG-003 debt repair: MarketId validation and RecipeDefinition bounds #288 control-plane tests pass — will pass when merged since its in-flight row is now allowed
• 5. backfill_merge_commits.py still fills commit after merge — unchanged, still reuses same function
• 6. Release tagging remains blocked on missing post-merge provenance — unaffected by this change

Checks

Check	Outcome	Evidence
python -m unittest discover -s scripts/tests -v	passed	All 449 tests passed in 6.155s, including target test
TypeScript canonical build	not_run	This is a Python control-plane change, not canonical code
C# legacy build	not_run	This is a Python control-plane change, not legacy code

Not checked

TypeScript and C# builds are not run because this change is confined to Python test code in scripts/tests/. The change does not affect canonical simulation code (src/) or legacy simulation code (TradeCraftSimulation/), so running those suites would verify unrelated systems.

Assumptions and unknowns

• The test now queries GitHub during CI. If GitHub is unreachable or auth fails, the test catches the exception and skips validation (not a failure). This is safe because implementation_status.py still validates the ledger independently.
• The fix reuses backfill.merge_commit() which already handles merge state lookup correctly per PR Make the ledger's merge provenance real #280.

Highest-risk area for review

The exception handling at lines 116-119: if GitHub query fails, the test silently skips validation rather than failing hard. This was a deliberate choice because the ledger is validated by the independent policy-guard check (implementation_status.py), so a transient network error should not gate a merge. However, a reviewer should confirm this trade-off is acceptable.

Remaining gate

No mandatory work remains. The fix is complete, tests pass, and it unblocks legitimate in-flight ledger rows while preserving the provenance guarantee for merged PRs.

Verdict: REQUEST_CHANGES

Gate: policy-guard check, status_lint.py step

The issue: The required policy-guard check is failing with:

status-lint: REQ-MARKET-003 was claimed by merged pull request(s) #293 but has no ledger row

Root cause: This is a pre-existing ledger integrity issue. PR #293 (REQ-MARKET-003) merged without adding its ledger row, leaving the registry inconsistent. This failure exists on master and blocks all pull requests from passing the policy-guard check.

What passed:

• All 449 repository tests pass, including the target test ✓
• TypeScript build: passed ✓
• C# .NET build: passed ✓
• policy_guard.py: passed ✓
• scope_guard.py: passed ✓
• implementation_status.py: passed ✓

The pull request itself: The code changes correctly implement the fix for issue #292. The test modification is sound and enables the legitimate in-flight ledger pattern.

Blocker: The status_lint.py failure is not PR #294's responsibility to fix—it is a pre-existing ledger state problem. I cannot merge while a required check is red per ACCEPTOR_RUNBOOK.md section 3.

This pull request is held at the ledger integrity gate until the pre-existing REQ-MARKET-003 ledger row issue on master is resolved.

REQUEST_CHANGES — d2fa44b

Required check failing: policy-guard

The required policy-guard check fails at the status_lint.py step due to a pre-existing ledger integrity issue: REQ-MARKET-003 (merged in PR #293) lacks its ledger row.

Verification results on this revision:

• Test suite (449 tests): passed ✓
• All 6 sub-steps of policy-guard up to status_lint.py: passed ✓
• Handoff completeness: complete ✓
• Changed artifacts: correctly declared ✓
• Issue #292 metadata: complete ✓

The pull request itself is sound. The fix for the provenance test is correct and unblocks the intended ledger pattern. However, I cannot merge while a required check is red. This gate (status_lint.py ledger validation) is not PR #294's responsibility to clear—it is a blocking condition on master that affects all pull requests.

Fix the upstream ledger row issue for REQ-MARKET-003, which will restore policy-guard to green, and this PR becomes mergeable.

AUTHOR handoff: Blocked by pre-existing gate failure

Branch: claude/issue-292-provenance-self-test
Tested revision: d2fa44b (Fix: Ledger provenance test to allow in-flight PRs with blank MERGE_COMMIT)

Work completed: The fix to scripts/tests/test_backfill_merge_commits.py is correct and passes all local verification:

• TypeScript: 439 tests passed, typecheck clean, build succeeded
• C#/.NET: 45 tests passed, build clean
• Control-plane tests: 449 passed

Blocking gate: The policy-guard check's status-lint step detects that REQ-MARKET-003 (claimed by merged PR #293) has no ledger row in docs/spec/implementation_status.csv. This is a pre-existing violation of the handoff contract from PR #293, not a defect in this PR's implementation.

Cannot proceed: Per AUTHOR_RUNBOOK.md section 8, this PR cannot be merged while a required check fails and the failure is not this run's responsibility to fix. The missing ledger row for REQ-MARKET-003 must be added by a separate AUTHOR run that cleans up the merge violation from PR #293.

Issue status: #292 set to status:blocked; the blocking gate is an external merge violation, not a defect in the test fix itself.

Refusal: Required check failing

Gate: policy-guard check at current head revision d2fa44b is in FAILURE state.

Reason: The status_lint step within policy-guard is detecting that REQ-MARKET-003 (claimed by merged pull request #293) has no ledger row in docs/spec/implementation_status.csv. PR #293's pull request body explicitly states: "Ledger row will be added in a follow-up pull request after this merge, per AGENTS.md Handoff rules." However, that follow-up PR has not been opened yet.

What this means for PR #294: PR #294's code changes are correct (test suite passes 449/449, TypeScript/C# builds clean). The test fix is logically sound. However, the merge is mechanically blocked because a required gate (policy-guard) is not green.

What blocks acceptance: No changes to this PR will resolve this gate. The issue is a pre-existing ledger state from PR #293. The merge can only proceed once:

1. A separate pull request adds the REQ-MARKET-003 ledger row to docs/spec/implementation_status.csv with the merge commit SHA from PR #293 (commit: bf526b3), OR
2. Master's policy-guard check returns to green status

Per AGENTS.md Section 2a and ACCEPTOR_RUNBOOK.md Section 3: every required check must be measured green at the current head revision. This PR cannot proceed while a required check is red on master.

Recommendation: Do not rework this PR. Open a follow-up PR to add the REQ-MARKET-003 ledger row as promised by PR #293, which will allow master's policy-guard to return to green, after which this PR #294 can be reviewed and merged cleanly.

Rework bound reached: 3 refusals on one pull request

Closed by the forge at head d2fa44ba, not by a reviewer. The bound is 3 REQUEST_CHANGES verdicts: a further round on a branch that has failed review this often costs more than a fresh start from master with the record in hand.

Refusals:

• 2026-09-08T04:03:45Z — ## Verdict: REQUEST_CHANGES (Fix ledger provenance test to allow in-flight PRs #294 (comment))

The commits stay reachable from this pull request. Issue #292 returns to status:ready with this record; the next AUTHOR run starts from master and reads every verdict above before claiming it.
