Review exact current head 4ccb3ff only against protected main 6eb06cd. This is the minimal Strix evidence successor to broad PR #965. Verify exact artifact/run/repository/head/digest binding, provider fail-closed behavior, process-group hardening, terminal checks, and all review findings. This is a request-only review, not approval or Merge authority. |

Review exact current head 2833d8a only against protected main 6eb06cd. This is the minimal Strix evidence successor PR #1009. The latest commit only models the Linux x86_64 runner in uv verification tests; full local suite is 978 passed with 16 subtests. Verify exact artifact/run/repository/head/digest binding, fail-closed provider behavior, process-group hardening, and terminal protected checks.

Exact-head Strix audit: run 31813452739/job 94809347457 executed trusted base workflow SHA 6eb06cd against PR head 2833d8a. It failed closed after 445 seconds because NVIDIA NIM produced agents.exceptions.ModelBehaviorError: Tool execute not found in agent strix; no vulnerability report or structured binding was produced. This is provider/model-tool-contract plus pull_request_target trusted-base evidence, not a source vulnerability and not a clean Strix result. The PR-head classifier is covered locally (9 pytest tests passed; required workflow smoke passed), but it is not privileged execution evidence until protected default-branch integration/dispatch. Keep Merge blocked pending terminal exact-head checks, independent approval, resolved threads, and structured same-head evidence. |

Pull request overview
OpenCode could not approve from deterministic current-head evidence because GitHub Checks have failed.
Findings
1. HIGH Current-head GitHub Checks - Fix failed required checks before approval
- Problem: Failed same-head checks remain for
2833d8a1c2f2cbb02387a2af752db51298cc64c4. - Root cause: The model-unavailable evidence fallback is allowed only when peer GitHub Checks are complete and clean.
- Fix: Read and fix the failed check logs below, then rerun the current-head checks.
- Regression test: Keep the model-unavailable fallback gated on an empty failed-check rollup.
Failed checks:
- Strix Security Scan/strix: FAILURE (https://github.com/ContextualWisdomLab/.github/actions/runs/31813452739/job/94809347457)
- Strix Security Scan/strix: failure (https://github.com/ContextualWisdomLab/.github/actions/runs/31813452739/job/94809347457)

Exact-head validation request (not an approval). Central PR head: 2833d8a; base: 6eb06cd. The trusted-base Strix run 31813452739/job 94809347457 failed after 599 seconds with agents.exceptions.ModelBehaviorError: Tool execute not found in agent strix; no vulnerability report or bound evidence was produced. Because this required workflow is pull_request_target/repository-dispatch based, that run executed the trusted workflow path rather than proving that the PR-head workflow change had executed. Please obtain an independent formal review, repair/verify the provider-tool contract on the trusted path, and rerun with repository, PR head, run/job, report path, and digest binding. This is an evidence/review request, not an approval or Merge instruction. |

Exact-head review request for current commit 7d98519.\n\nThe ADR/doctoring record now binds the central rerun evidence: predecessor head 2833d8a, run 31813452739 attempt 2, job 94912967996, artifact 9236314064, report SHA-256 8d35921b389a7a88d6b03240bfe7283d395318192028e75ddd626561fcc29982, and run.json SHA-256 c7e7bd734cfe544d3b5ac4d9eb98572f304f9bdd56f2bcdf4ad974c75081664a. The report was zero-finding, but run.json had null repository/head/commit metadata and the artifact had no evidence-binding.json. The record also documents that pull_request_target used protected main's older workflow, so the PR branch's provenance validation could not self-prove its own required run.\n\nThe docs-only push invalidates predecessor checks, Strix evidence, and review snapshots. Please produce a fresh independent review and exact-head terminal checks for 7d98519. Do not treat the old green status, an unbound provider report, or a manual/status-only approval as a clean gate. |
|
Correction to the exact-head request: the latest current commit is d22097a. The follow-up records the five live default-branch Dependabot alerts and requires post-fix alert/lock-hash verification; the prior 7d98519 request is superseded. Please rerun independent review and all exact-head checks for d22097a. |
|
Security finding remediated on exact current commit 532c71a.\n\nThe predecessor exact-head Strix run 31847453432 / job 94916734763 failed closed with MEDIUM vuln-0001 in redact_sensitive_log.py. I reproduced the report's PoC, fixed known provider-token coverage, applied the credential pass to serialized JSON values, preserved valid JSON quoting for sensitive-key redaction, and added trusted contract regressions for JSON non-sensitive keys, sensitive keys, and assignments. Local direct checks, Python compile, shell syntax, and filtered Strix contract execution passed. The fixture is constructed at runtime and contains no committed secret.\n\nPlease run fresh exact-head checks and Strix for 532c71a, then obtain an independent review. The predecessor failure remains a real finding; do not downgrade it to a provider flake or use status-only/manual approval. |

Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
-
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head. -
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
-
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present. -
Result: REQUEST_CHANGES
-
Reason: coverage-evidence result was
failure, so required test/docstring evidence was not proven for current head532c71a274556330e71af17c3ec9d3b0bd5066b2. -

📝 Info: IS_PR_EVIDENCE_RUN stays true for merged full-tree scans
STRIX_TARGET_PATH and STRIX_DISABLE_PR_SCOPING were updated to exclude the new merge_state == 'merged' path (.github/workflows/strix.yml:854,870), but IS_PR_EVIDENCE_RUN (strix.yml) still evaluates to true for merged dispatches because it only checks client_payload.pr_number != ''. That value drives STRIX_CHILD_REQUIRE_EXECUTABLE_INTEGRITY in strix_quick_gate.sh:2382. For a merged full-tree scan this makes the child require executable integrity, which is a hardening rather than a break, so this is not a functional bug, but the inconsistency (PR-evidence semantics kept true while PR scoping is disabled) is worth a deliberate confirmation.

🔍 Post-merge Strix provenance requires run.json head metadata that base evidence often lacks
The new Validate Strix report provenance step (strix.yml) runs on always() && steps.gate.outputs.enabled == 'true' and fails closed (exit 1) unless it finds exactly one run.json whose head_sha/commit_sha (or nested scan_results.*) equals the evidence head SHA. The doctoring in strix-provider-evidence-fail-closed.md repeatedly observes that Strix run.json often carries null repository/head/commit metadata. If Strix does not populate those fields when scanning the trusted workspace (especially the merged-commit tree for the new merge_state=merged path, where the checked-out SHA is the merge commit but evidence_head_sha is the original PR head), every such run would produce zero eligible candidates and the job would fail. This is central to the PR's intent and presumably validated by the author, but it hinges on Strix's internal run.json contents which cannot be verified from this diff. Worth confirming that a real post-merge/default-branch dispatch actually yields a matching binding rather than failing closed unconditionally.

📝 Info: _redact_assignments key-run skip drops digit-prefixed sensitive assignments
The performance optimization in _redact_assignments (redact_sensitive_log.py) now fast-forwards over an entire contiguous KEY_CHARS run when _consume_sensitive_assignment returns None. Because _consume_sensitive_assignment bails with None when the run starts with a digit (redact_sensitive_log.py:73), an input like 9token=secret now skips the whole 9token run and never retries token=secret starting at offset 1, whereas the previous char-by-char advance would have redacted it. This is a genuine behavior change but only affects sensitive keys glued to a preceding digit-led key-char run with no separator, which is very unlikely in real CI text (env var names cannot start with digits, and JSON is handled by _redact_json). Flagging for awareness rather than as a bug given the negligible realistic trigger.

📝 Info: OpenCode wrapper now accepts review-control flags from client_payload with safe defaults
The OpenCode dispatch wrapper changed the review-control env values from hardcoded literals to ${{ github.event.client_payload.<flag> || '<default>' }} (agent-mention-opencode-dispatch.yml). Because the downstream Validate exact invocation payload step still hard-asserts TRIGGER_REVIEWS==true, REVIEW_DISPATCH_LIMIT==1, ENABLE_AUTO_MERGE==false, UPDATE_BRANCHES==false, MERGE_MODE==disabled before the HMAC/invocation-key check, a malicious dispatch that supplies e.g. enable_auto_merge=true still fails closed. The router no longer emits these keys (keeping the payload at 9 properties), so the defaults apply in normal operation. Behavior is preserved; noting the widened input surface for reviewer awareness.

📝 Info: Strix run-name merge_state suffix is parsed only by the scheduler dedup
The Strix run-name now appends :${{ client_payload.merge_state || 'open' }} (strix.yml). The only consumer that parses the @<sha> display-title suffix is active_review_run_refs in pr_review_merge_scheduler.py, which was correctly updated to partition(":") and handle both suffixed and legacy (no-colon) titles against required_merge_state. OpenCode dispatch titles remain colon-free and default to required_merge_state=None, so they still match. No other run-title parser (failed-check collector, opencode approval) keys off the @<sha> suffix, so the added :state suffix does not break them.

…, not 17) Devin Review caught an internal inconsistency: the entry said "17 open PRs" but listed and later referenced 16. Corrected the count and clarified that the two queued-but-unposted PRs (#1147, #1009) never received a comment and need no retraction reply.

Triage sweep: this branch has had no owner activity since Aug 29 ( Given the PR body's own "evidence-convergence contract" scope, the "status: blocked"/"priority: critical" labels, and how much of the central review/dispatch pipeline both sides have independently moved on this surface since Aug 14, this isn't a mechanical rebase — reconciling it correctly requires understanding which of the two evolutions of each script/workflow is now current and how they compose, not just picking a side per hunk. Leaving it for the dedicated owner rather than guessing; no changes pushed, branch left as-is. Generated by Claude Code |

main replaced the 4063-line scheduler monolith this branch was built on with a 241-line facade plus a 6222-line core, so all four scheduler conflicts had ours 656/1322/611/359 lines against theirs 2/17/2/15. That is the #1009 shape, but it is relocatable here, not a re-implementation: all 16 functions the branch's hunks anchor on still exist in pr_review_merge_scheduler_core.py. Method: take main's facade, then replay the branch's own diff against the core module (git apply --3way with the path rewritten). 15 of 17 hunks landed cleanly. The two that did not were placement collisions, resolved by applying the branch's intent at core's existing sites instead of at the branch's: - core already owns active_workflow_runs (23 references vs the branch's 4) and had grown server-side filters and memoization. Kept core's function and rerouted its single call to run_github_actions_for_repository(repo, args), which is what the branch's version of that function did. - core calls cancel_stale_pr_runs at a different point in inspect_pr than the branch did. Wrapped core's call site with the branch's repository_dispatch_target(repo).casefold() == repo.casefold() guard. Other files: - .github/workflows/pr-review-merge-scheduler.yml: main deleted the entire 684-line org-queue-sweep job and pins its absence (assert_file_not_contains 'org-queue-sweep'). Took main's side. Provenance checked: org-queue-sweep is 4x at the merge base and 4x on the branch, 0x on main, and the branch's own change to this file is only +2 lines, so nothing the branch authored is lost with the job. One of those two lines (SCHEDULER_WORKFLOW_TOKEN) belonged to org-queue-sweep; the other had already auto-merged into the job main kept. - tests/test_opencode_agent_contract.py: the branch pinned count('SCHEDULER_WORKFLOW_TOKEN: ...') == 2. One of those two occurrences was org-queue-sweep's, so the merged tree has 1. Changed the pin to 1 with the reason in a comment. - tests/test_pr_review_autofix_nvidia_nim_contract.py: REVIEW_DISPATCH_BLOB_SHA pins git hash-object on opencode-review-dispatch.yml. Both sides are correct for their own tree and both wrong for this merge (branch ea13d12, main 26e8555). Recomputed from the merged file: d7f7c18. - tests/test_pr_review_merge_scheduler.py: kept both sides (main's 337 lines and the branch's 32). The conflict boundary falls between complete top-level functions. - CHANGELOG.md: kept both entries. Evidence: - uvx ruff check --select F821 scripts/ci tests: All checks passed - full suite, branch head b297581 (unmerged): 1920 passed, 0 failed - full suite, this merge: 2919 passed, 0 failed - PR's own oracle (test_lint_github_workflows.py, test_pr_review_merge_ scheduler.py, test_pr_review_autofix_nvidia_nim_contract.py): 372 passed - coverage: TOTAL 100%; pr_review_merge_scheduler_core.py 2557/2557 100%. With fail_under = 100 this is the independent proof that both relocated edits are reached, not merged-in-but-dead. - negative control: deleting the SCHEDULER_WORKFLOW_TOKEN workflow line makes test_merge_scheduler_uses_escalating_mutation_credentials fail by name - interrogate: PASSED (minimum 100.0%) Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Status
Ready-for-review bounded successor to broad historical PR #965. The branch is based on protected
main@c47afc2dc68488292c1db7c9d6f82dcd5360f181; no rebase, force-push, Admin bypass, reviewer substitution, or evidence transfer is used. Exact current head remains4b3cdb77599a3c67817bccf0e45a2058da52a122and GitHub currently reports it mechanically mergeable.Scope
This branch contains the Strix exact-head evidence boundary and its directly required control-plane contracts:
strix-reportsselection;repository_dispatchsize, property-count, event-type, identity, and complete-payload binding;The established independent read-only reviewer workflow remains the protected-main version. Strix post-merge evidence semantics are owned and tested by
.github/workflows/strix.ymlandscripts/ci/collect_failed_check_evidence.sh, not coupled to the independent reviewer.Every check, review, artifact, comment, or verdict bound to an earlier head is historical only.
Security contracts
Fresh consumer contradiction: report/artifact/verdict semantics

It proves that artifact existence, report content, remediation status, and gate verdict are separate evidence authorities and must not contradict one another.
Required evidence-convergence contract
The dedicated owner should preserve the existing exact-head/artifact/digest binding and add or verify machine-checkable semantics so that:
resolved/fixedremediation state cannot be inferred merely because a sandbox patch was attempted or proposed—successful mutation plus post-fix verification must be explicit evidence, otherwise remediation remains unverified/unresolved;incomplete/invalid evidence, not as source success and not as an invented source vulnerability;Add deterministic RED fixtures using a synthetic bound report that reproduces the #164 contradiction before changing production evidence logic. Do not weaken required Strix, synthesize success, broadly trust model-authored
resolvedtext, or mutate the consumer repository to satisfy stale scanner prose.Verified repair lineage
Workflow run
31944747372, job95158934524repaired the stale quick-gate ownership contract test-first:compileall, andgit diff --checkpassed;The repair removes stale assertions that expected manual Strix evidence logic inside the immutable reviewer. Existing focused assertions continue to bind exact-head artifact download, status description, digest, path, and explicit superseded-failure behavior at the actual Strix and failed-check collector boundaries. Those predecessor repair results establish lineage only; any new production change for the contradiction contract must regenerate its own exact-head evidence.
Merge contract
Fresh exact-head quality, security, supply-chain, Strix, and semantic-review evidence must bind to
4b3cdb77599a3c67817bccf0e45a2058da52a122or to any later exact head created by the dedicated owner. Merge only after the unchanged final head has terminal required checks, zero valid unresolved findings, qualifying independent non-author approvals including an approval after the latest push where live protection requires it, and ordinary protected-branch acceptance. Do not self-approve, dismiss a valid current finding, use Admin bypass, substitute status-only evidence, or accept an unbound/contradictory artifact.After protected integration, affected consumer repositories—including the then-current Inkspan #164 head if still open—must produce new authoritative same-head Strix evidence before their own merges.
