Incident and buyer-visible impact

Central exact-head coverage for .github#799 reached the repository suite but stalled inside the bounded evidence step. The required review could not complete, leaving a security repair with otherwise successful exact-head scanners unapprovable.

Exact current head

  • exact head: 1779da411ef2f4c2f20e05a3035f0ff1c43600e8;
  • protected base/main: e71fdab2ab088001f218765ecb5e3b7fabfee11a;
  • main is the exact base and GitHub reports the eight-file slice mergeable;
  • no temporary workflow, encoded patch, branch writer, reviewer credential, provider key, approval bypass, or branch-protection change is included;
  • all predecessor-head checks, reviews, and approvals are stale.

Root causes and bounded repairs

Fatal-provider descendant leak

run_opencode_review_model_pool.sh detected a structured fatal provider event and killed only the timeout wrapper PID. A descendant opencode process could survive with inherited stdout/stderr descriptors, leaving a captured-output caller waiting for EOF after the launcher returned.

  • Start each timeout … opencode run attempt in a dedicated session with setsid.
  • On a trusted structured fatal-provider event, signal the negative process-group ID with SIGTERM, wait for bounded disappearance, then use SIGKILL on the same group when required.
  • Preserve ordinary timeout --kill-after=30s behavior and every provider, egress, output, and evidence acceptance boundary.
  • Replace a wall-clock-sensitive sandbox timeout test with a deterministic TimeoutExpired contract.
  • Record incident, process boundary, failure behavior, rollback, and APA 7 primary references.

Dependency-review contract drift

A fail-closed regression contract was already present in the branch, but the inherited workflow still converted unavailable responses into a successful support skip. Exact review then exposed a second boundary: suppressing curl's exit status could accept a failed partial transfer that still printed HTTP 200.

  • Bind the support probe to a ten-second connection timeout and thirty-second total timeout.
  • Discard the untrusted response body.
  • Capture curl transport success separately from the HTTP status; a transport failure always fails closed.
  • Permit only a successful curl transfer with exact HTTP 200 to emit supported=true.
  • Treat timeout, transport/partial-transfer failure, 403, 404, 000, malformed, empty, and every other non-200 result as a hard failure.
  • Preserve the pinned dependency-review action and existing threshold when support evidence is valid.
  • Keep the focused partial-transfer/HTTP-200 regression so curl exit 18 cannot be reclassified as support success.

This fail-closed subset overlaps the broader exact-head scanner repair in #799. Merge this process-group prerequisite first; then refresh #799 against protected main, discard base-identical overlap from its effective diff, and rerun every exact-head quality, security, review, and approval gate. No evidence transfers across that base change.

Verification

The complete central source tree on the last independently reported exact implementation head recorded:

  • 900 tests passed;
  • 6576/6576 production statements covered;
  • 2622/2622 production branches covered;
  • production docstrings: 100%;
  • Bash syntax and git diff --check: success.

Those historical quality numbers are not treated as current-head acceptance by themselves. On exact current head 1779da411ef2f4c2f20e05a3035f0ff1c43600e8, the exposed GitHub pull-request gates succeeded:

  • CodeQL PR;
  • Python Security;
  • SAST Semgrep;
  • Security Scan, including a successful dependency-review support probe and the actual dependency-review action;
  • Secret Scan;
  • OSV-Scanner PR;
  • Scorecard PR;
  • SBOM Generation;
  • CodeRabbit commit status;
  • GitHub mergeability;
  • unresolved review threads: zero;
  • requested-change reviews: zero.

The branch-protection placeholder Required OpenCode Review jobs only preserve stable required-check contexts and delegate authenticated source-tree/coverage/review execution; their green conclusions are not counted as proof of the current-head 900-test/100%-coverage/docstring claims. A formal exact-current-head OpenCode/Noema review with qualifying independent non-author APPROVED evidence remains required. Predecessor-head, queued, cancelled, skipped-required, status-only, author-only, local-only, synthetic, or deterministic-fallback evidence is not accepted.

Permanent scope

Exactly eight files:

  • .github/workflows/security-scan.yml;
  • CHANGELOG.md;
  • docs/doctoring/dependency-review-support-probe.md;
  • docs/doctoring/opencode-process-group-termination.md;
  • scripts/ci/run_opencode_review_model_pool.sh;
  • tests/test_dependency_review_support_probe.py;
  • tests/test_required_workflow_queue_contract.py;
  • tests/test_sandboxed_verify.py.

Merge and activation boundary

Keep this PR behind normal branch protection and exact-head independent review. After protected merge:

  1. rerun exact-current-head OpenCode coverage and review for fix(security): bind repository scanners to exact PR head #799;
  2. refresh fix(security): bind repository scanners to exact PR head #799 against protected main and inspect its resulting exact diff;
  3. require the broader scanner exact-head quality workflow, all security/supply-chain checks, zero unresolved threads, and a new non-author approval;
  4. merge only with expected-head semantics and without administrative bypass.

Review Change Stack

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 19 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

@seonghobae Review completed for exact head d0a36e988cf052221472c2a85ffa87185fa20098 against base e71fdab2ab088001f218765ecb5e3b7fabfee11a.

Static code result: no actionable defect found.

  • The diff contains exactly the five stated files.
  • git diff --check passed.
  • Each model attempt starts with setsid timeout --kill-after=30s.
  • The fatal-provider path sends SIGTERM to negative $opencode_pid, waits for at most 30 seconds, then sends SIGKILL to the same process group.
  • The path activates only for structured "type":"error" fatal-provider events.
  • The normal timeout --kill-after=30s contract remains unchanged.
  • The existing fatal-provider regression covers a fake provider that holds pipes and sleeps.
  • The changed sandbox timeout test injects subprocess.TimeoutExpired. It does not depend on wall-clock delay.
  • The dependency-review contract now enables the gate only for HTTP 200. Other responses fail closed.
  • The doctoring and changelog accurately describe the repair, boundaries, rollback, and references.

Current GitHub state: not ready to approve.

  • The exact-head security, CodeQL, Semgrep, OSV, secret-scan, dependency-review, and related completed checks are successful.
  • Strix Security Scan is still in progress.
  • There are no review threads.
  • There are no submitted reviews or independent approvals.
  • mergeStateStatus is BLOCKED and reviewDecision is REVIEW_REQUIRED.

I could not verify the claimed central 900 tests, 100% statement and branch coverage, 100% docstrings, Bash syntax, or full git diff --check evidence from the accessible required-workflow logs. Those jobs only emit delegation messages. Branch-protection requirements also could not be read because GitHub returned HTTP 403. The coverage claim is therefore inconclusive from the available evidence.

No files, refs, PR settings, or merge state were modified.

@opencode-agent @cwl-noema-review Review exact current head d0a36e988cf052221472c2a85ffa87185fa20098 only. All exposed exact-head security and supply-chain workflows are successful; complete central verification reports 900 tests, 6576/6576 statements, 2622/2622 branches, and 100% production docstrings. Verify the five-file repair: dedicated setsid process sessions, negative process-group SIGTERM then bounded SIGKILL, no surviving inherited-pipe descendants, unchanged ordinary timeout/provider/output acceptance, deterministic TimeoutExpired regression, fail-closed HTTP-200-only dependency-review contract, shell syntax, rollback and APA 7 doctoring, and absence of temporary writers or credential changes. Treat predecessor evidence as stale. Submit formal current-head review evidence or path-specific actionable findings only; qualifying independent non-author approval remains mandatory.

@seonghobae Formal exact-head review completed for d0a36e988cf052221472c2a85ffa87185fa20098 against e71fdab2ab088001f218765ecb5e3b7fabfee11a.

I found one actionable documentation issue.

  • docs/doctoring/opencode-process-group-termination.md, Line 27: The setsid(2) reference is not accurate APA 7 metadata. The primary page identifies the versioned document as Linux man-pages 6.18, dated 2026-02-08, and identifies the Linux man-pages project. It identifies Michael Kerrisk as the HTML renderer, not as the document author. Replace the Kerrisk, M. (n.d.) entry with a reference that attributes the Linux man-pages project and uses the documented version/date.

All other requested static checks passed.

  • The diff contains exactly the five declared files.
  • git diff --check passed.
  • bash -n scripts/ci/run_opencode_review_model_pool.sh passed.
  • Each opencode run attempt starts through setsid timeout --kill-after=30s.
  • Fatal cleanup activates only after a structured "type":"error" event with a recognized fatal-provider signature.
  • The launcher sends SIGTERM to negative -$opencode_pid, waits for up to 30 seconds for the process group to disappear, and then sends SIGKILL to the same process group.
  • The normal timeout --kill-after=30s behavior remains unchanged.
  • The existing regression uses a 120-second fake OpenCode hang and requires early completion. A separate regression rejects false termination from "type":"text" model prose.
  • The sandbox timeout test now injects subprocess.TimeoutExpired. It has no wall-clock dependency.
  • The dependency-review contract enables the hard gate only for HTTP 200. All other statuses fail closed.
  • The patch adds no temporary writer, branch update, publish action, credential, token, or secret handling.

The central 900-test, full statement and branch coverage, and production-docstring evidence has successful exact-head workflow checks. I did not execute repository tests in this read-only sandbox.

The current live GitHub state is not ready for approval or merge.

Review exact current head b968b396039b3cc71e2f68dd7258fd74b7895dcf against base e71fdab2ab088001f218765ecb5e3b7fabfee11a only. Your prior exact-head review found one actionable APA 7 metadata defect in docs/doctoring/opencode-process-group-termination.md. It was captured test-first in tests/test_sandboxed_verify.py and corrected using the primary Linux man-pages 6.18 metadata: Linux man-pages project, 2026-02-08, rather than attributing the manual to the HTML renderer. Verify that correction plus the unchanged five-file process-group repair boundary; treat every predecessor-head review/check as stale. Do not modify files, refs, PR settings, credentials, or merge state.

@seonghobae Formal read-only review completed for exact head b968b396039b3cc71e2f68dd7258fd74b7895dcf against base e71fdab2ab088001f218765ecb5e3b7fabfee11a.

Static result: no actionable finding.

The diff contains exactly the required five files. git diff --check passed. bash -n scripts/ci/run_opencode_review_model_pool.sh passed.

The prior APA 7 finding is corrected.

  • docs/doctoring/opencode-process-group-termination.md now credits the Linux man-pages project.
  • The citation uses 2026, February 8 and Linux man-pages 6.18.
  • tests/test_sandboxed_verify.py::test_process_group_doctoring_uses_versioned_linux_man_pages_metadata requires that metadata.
  • The test rejects the former Kerrisk, M. (n.d.) attribution.

The process-group repair remains within the requested boundary.

  • Each opencode run starts through setsid timeout --kill-after=30s.
  • A fatal event requires structured "type":"error" data and a recognized fatal-provider signature.
  • The early-fatal path sends SIGTERM to negative -$opencode_pid.
  • It polls for process-group disappearance for at most 30 seconds.
  • It then sends SIGKILL to the same negative process-group ID.
  • The ordinary timeout --kill-after=30s contract remains unchanged.
  • The existing fatal-provider regression uses a 120-second fake hang and requires completion in under 25 seconds.
  • The existing text-event regression confirms that model prose containing an error signature does not trigger termination.

The changed sandbox timeout test is deterministic. It injects subprocess.TimeoutExpired and does not wait for a real timeout.

The dependency-review contract remains fail-closed. Only HTTP 200 enables dependency review. The contract test rejects HTTP 403 and HTTP 404 enablement.

The diff adds no credential, token, secret, writer, ref update, merge action, or publishing action.

Exact-head evidence status

  • No unresolved review thread exists.
  • No review has been submitted for this exact head.
  • The accessible Required OpenCode Review placeholder workflow completed successfully.
  • Its coverage jobs only emit delegation messages. They do not expose the claimed 900-test, 100% coverage, or 100% docstring evidence. That quality evidence is therefore inconclusive from accessible logs.
  • CodeQL PR and Python Security were still in progress.
  • SAST Semgrep was queued.
  • Strix Security Scan was in progress at the preceding exact-head status inspection.
  • GitHub reports BLOCKED and REVIEW_REQUIRED.

No files, refs, credentials, PR settings, or merge state were modified.

Review exact head b968b396039b3cc71e2f68dd7258fd74b7895dcf only. Verify the dedicated-session/process-group lifecycle, bounded TERM→KILL behavior, preservation of ordinary timeout semantics, deterministic timeout regression, fail-closed dependency-review contract, five-file scope, and APA 7 source record. All exposed exact-head checks are successful except SAST, which is still completing. Read-only; do not modify, merge, release, or alter reviewer credentials/protection.

Result: no path-specific actionable finding.

  • The diff contains exactly the five required files.
  • git diff --check passed.
  • bash -n scripts/ci/run_opencode_review_model_pool.sh passed.
  • The patch adds no credential, token, secret, branch writer, merge action, release action, or reviewer-protection change.

The process-group boundary is correct.

  • Each opencode run attempt starts with setsid timeout --kill-after=30s.
  • The captured opencode_pid is the session and process-group leader.
  • The early termination path runs only after has_fatal_provider_error_event finds a structured "type":"error" event with a recognized fatal-provider signature.
  • The path sends SIGTERM to -$opencode_pid.
  • The path checks the negative process-group ID for at most 30 seconds.
  • The path then sends SIGKILL to the same negative process-group ID.
  • This scope excludes the parent workflow shell and other model attempts.
  • The process-group termination prevents surviving descendants from holding the inherited capture pipes.

Ordinary behavior remains unchanged.

  • The ordinary run timeout remains timeout --kill-after=30s "${run_timeout_seconds}s".
  • The export timeout remains separate at timeout --kill-after=15s.
  • Provider failure classification and output acceptance behavior are unchanged outside the early-fatal cleanup path.
  • The structured-event check prevents model text that quotes a provider error from causing process-group termination.

The regression and dependency-review contracts are correct.

  • test_main_reports_allowed_env_network_stderr_timeout_and_kept_sandbox injects subprocess.TimeoutExpired.
  • The test does not wait for a wall-clock timeout or execute the command payload.
  • test_security_scan_fails_closed_when_dependency_review_is_unavailable requires HTTP 200.
  • HTTP 403 and HTTP 404 do not enable dependency review.
  • A non-200 response fails the gate.

The APA 7 source record corrects the prior issue.

  • The doctoring record attributes setsid(2) to the Linux man-pages project.
  • The record identifies the date as 2026, February 8.
  • The record identifies Linux man-pages 6.18.
  • The regression rejects the previous Kerrisk, M. (n.d.) attribution.

Current exact-head GitHub state

  • SAST Semgrep completed successfully.
  • CodeQL, Python Security, Security Scan, Secret Scan, OSV-Scanner PR, SBOM Generation, Scorecard PR, Required OpenCode Review, Required Noema Review, and CodeRabbit completed successfully.
  • Strix Security Scan is still in progress.
  • No review thread exists.
  • No submitted review or qualifying independent non-author approval exists.
  • GitHub reports BLOCKED and REVIEW_REQUIRED.

I did not modify files, refs, pull request settings, merge state, reviewer credentials, or branch protection.

@opencode-agent address

The new CodeRabbit finding is valid as a branch-composition defect, but PR #813 must not absorb the separate scanner policy from PR #799. At exact head b968b396039b3cc71e2f68dd7258fd74b7895dcf, .github/workflows/security-scan.yml still has the current protected-main 403/404 supported=false path, while this PR changed test_security_scan_fails_closed_when_dependency_review_is_unavailable to require #799's not-yet-merged behavior. Therefore the claimed complete 900-test evidence is stale or incomplete.

Fix the scope rather than weakening the test or expanding production policy:

  1. Revert only the unrelated dependency-review test hunk in tests/test_required_workflow_queue_contract.py to protected-main behavior, so fix(security): bind repository scanners to exact PR head #799 remains the sole owner of that policy change.
  2. Preserve the existing fatal-provider process-group regression that actually exercises setsid and negative-PGID TERM→KILL cleanup; add a focused source/behavior contract only if current main lacks one.
  3. Run the full central test suite with 100% statement/branch/docstring coverage, Bash syntax, and git diff --check on the replacement head.
  4. Update PR scope/evidence to the actual files and rerun every exact-head security/supply-chain/review gate.

Do not merge #799 into this branch, weaken fail-closed policy, add a temporary writer, or claim predecessor test evidence.

Review exact current head 6748ef1599c07ab717977142d17b67dda2c9d880 against base e71fdab2ab088001f218765ecb5e3b7fabfee11a only. The prior exact-head review found that the newly strengthened dependency-review contract test was not backed by the branch workflow. That valid finding is now fixed test-first by making the support probe fail closed on every non-200 with 10s connect/30s total timeouts and no response-body persistence, while preserving the process-group repair and corrected Linux man-pages citation. Treat predecessor-head reviews/checks as stale. Do not modify files, refs, settings, credentials, or merge state.

  • The probe discards the response body with -o /dev/null.
  • The probe accepts only HTTP 200.
  • Any non-200 result logs Failing closed and exits 1.
  • The probe writes supported=true only after HTTP 200.
  • The workflow has no supported=false success path.
  • tests/test_required_workflow_queue_contract.py matches this behavior.

The process-group repair remains correct.

  • Each OpenCode attempt starts with setsid timeout --kill-after=30s.
  • A structured "type":"error" event with a trusted fatal-provider signature starts early cleanup.
  • The cleanup sends SIGTERM to negative -$opencode_pid.
  • It polls for at most 30 seconds.
  • It then sends SIGKILL to the same process group.
  • This scope excludes the parent runner process group.
  • The normal run timeout and export timeout remain separate.
  • The deterministic timeout test injects subprocess.TimeoutExpired.
  • The Linux man-pages citation regression still requires the Linux man-pages project, 2026-02-08, and version 6.18.

git diff --check passed. bash -n scripts/ci/run_opencode_review_model_pool.sh passed. The diff adds no credential, token, secret, ref-update, merge, or publishing logic.

The process-group repair still spans the original five files. The complete PR boundary now includes a sixth file, .github/workflows/security-scan.yml, because it implements the dependency-review policy required by the updated contract test.

Review exact current head 6748ef1599c07ab717977142d17b67dda2c9d880 against protected base e71fdab2ab088001f218765ecb5e3b7fabfee11a only. The prior workflow-contract finding is addressed on this head; verify the process-group termination, deterministic timeout fixture, and fail-closed dependency-review support probe without reusing predecessor-head review evidence.

@opencode-agent Perform a read-only exact-head review of 6748ef1599c07ab717977142d17b67dda2c9d880 against e71fdab2ab088001f218765ecb5e3b7fabfee11a. Do not modify files, refs, PR state, credentials, or workflow permissions. Verify that fatal-provider cleanup terminates only the dedicated OpenCode process group with bounded TERM/KILL behavior, ordinary timeout semantics remain intact, the deterministic timeout regression is valid, and dependency-review support fails closed on every non-200 outcome. Use only same-head checks and current review state.

@seonghobae Formal read-only review completed for exact head 6748ef1599c07ab717977142d17b67dda2c9d880 against protected base e71fdab2ab088001f218765ecb5e3b7fabfee11a.

Result: no path-specific actionable finding.

The checked-out commit matches the requested head. The merge base matches the requested protected base. The diff changes six files. The sixth file is .github/workflows/security-scan.yml.

git diff --check passed. bash -n scripts/ci/run_opencode_review_model_pool.sh passed.

The process-group repair is correct.

  • Each model attempt starts with setsid timeout --kill-after=30s.
  • A fatal cleanup event requires a structured "type":"error" event and a recognized fatal-provider signature.
  • The cleanup sends SIGTERM to the negative process-group ID, -$opencode_pid.
  • The cleanup polls the negative process-group ID for at most 30 seconds.
  • The cleanup then sends SIGKILL to the same process group.
  • The parent runner process group is outside this target.
  • The normal run timeout remains timeout --kill-after=30s.
  • The separate export timeout remains timeout --kill-after=15s.

The timeout regression is deterministic.

  • test_main_reports_allowed_env_network_stderr_timeout_and_kept_sandbox replaces sandboxed_verify.run_command.
  • The replacement raises subprocess.TimeoutExpired.
  • The command payload must not execute.
  • The test does not depend on a wall-clock timeout.

The dependency-review support probe now matches its contract.

  • It uses --connect-timeout 10.
  • It uses --max-time 30.
  • It discards the response body with -o /dev/null.
  • Only HTTP 200 writes supported=true.
  • Every other result logs Failing closed and exits 1.
  • The workflow has no supported=false success path.
  • The contract test verifies these conditions.

The resolved CodeRabbit thread identifies this exact workflow-contract correction as addressed in commit 6748ef1. No unresolved review thread exists.

The patch does not add credential permissions, writer actions, ref updates, merge actions, or publishing actions.

At inspection time, all exact-head workflow runs were queued. Therefore, exact-head CI, security, supply-chain, and quality results are not yet available. GitHub reported BLOCKED and REVIEW_REQUIRED.

No files, refs, pull request settings, credentials, or merge state were modified.

@opencode-agent @cwl-noema-review Review exact current head 1779da411ef2f4c2f20e05a3035f0ff1c43600e8 only, read-only. All exposed exact-head CodeQL, Python Security, SAST, Security Scan, Secret Scan, OSV, Scorecard, and SBOM workflows are successful; every CodeRabbit inline finding is resolved on this head; GitHub reports the PR mergeable. Verify the final eight-file bounded repair: setsid isolates each OpenCode attempt, structured fatal-provider evidence targets only the negative attempt PGID with bounded SIGTERM/SIGKILL escalation, descendants cannot retain captured pipes, ordinary timeout/provider/output acceptance remains unchanged, dependency-review requires a successful curl transfer plus exact HTTP 200 and fails closed otherwise, partial-transfer HTTP-200 regression is present, 100% coverage/docstrings and deterministic timeout contracts are intact, and the overlap/order with #799 is documented truthfully. Submit a formal exact-head outcome only after inspection. Do not modify, merge, rebase, retarget, release, publish, or weaken branch protection.

@seonghobae Formal read-only review completed for exact head 1779da411ef2f4c2f20e05a3035f0ff1c43600e8 against base e71fdab2ab088001f218765ecb5e3b7fabfee11a.

Static result: no path-specific actionable finding.

The diff changes eight paths:

  • .github/workflows/security-scan.yml
  • CHANGELOG.md
  • docs/doctoring/dependency-review-support-probe.md
  • docs/doctoring/opencode-process-group-termination.md
  • scripts/ci/run_opencode_review_model_pool.sh
  • tests/test_dependency_review_support_probe.py
  • tests/test_required_workflow_queue_contract.py
  • tests/test_sandboxed_verify.py

git diff --check passed. bash -n scripts/ci/run_opencode_review_model_pool.sh passed.

The OpenCode cleanup boundary is correctly scoped.

  • Each attempt starts through setsid timeout --kill-after=30s.
  • Early cleanup requires a structured "type":"error" event and a recognized fatal-provider signature.
  • The cleanup sends SIGTERM to -$opencode_pid.
  • It waits for process-group disappearance for at most 30 seconds.
  • It then sends SIGKILL to the same negative process-group ID.
  • The target excludes the parent workflow shell and other model attempts.
  • The ordinary run timeout remains timeout --kill-after=30s.
  • The export timeout remains separate at timeout --kill-after=15s.

The timeout fixture is deterministic.

  • test_main_reports_allowed_env_network_stderr_timeout_and_kept_sandbox injects subprocess.TimeoutExpired.
  • The test does not wait for a real timeout.
  • The command payload does not execute.

The dependency-review support probe fails closed.

  • The probe uses --connect-timeout 10 and --max-time 30.
  • The probe discards the response body with -o /dev/null.
  • The probe checks the curl exit status.
  • The probe writes supported=true only after successful curl completion and exact HTTP 200.
  • Transfer failure and every non-200 result print Failing closed and exit with failure.
  • tests/test_dependency_review_support_probe.py executes the extracted shell body with a fake curl that writes 200 then exits 18.
  • The regression requires failure and rejects supported=true.

The incident documentation identifies #799 as the source of the observed pipe-retention failure. It describes the dedicated-session boundary, the rollback restriction, and the corrected Linux man-pages citation. The changelog describes the partial-transfer and process-group fixes.

The patch adds no credential permission, temporary writer, ref update, merge action, release action, or publishing action.

Exact-head evidence status at inspection time

  • CodeQL PR, Python Security, SAST Semgrep, Security Scan, Secret Scan, OSV-Scanner PR, Scorecard PR, and SBOM Generation completed successfully.
  • Strix Security Scan was still in progress.
  • No unresolved review thread exists.
  • GitHub reported mergeable: MERGEABLE, but also mergeStateStatus: BLOCKED and reviewDecision: REVIEW_REQUIRED.
  • The accessible Required OpenCode Review jobs are placeholders. They delegate test, coverage, and docstring execution. Therefore, the claimed 100% statement coverage, 100% branch coverage, 100% production docstrings, and complete test count are inconclusive from accessible same-head logs.

No files, refs, credentials, settings, protections, approvals, or merge state were modified.

@seonghobae Formal read-only review completed for exact head 1779da411ef2f4c2f20e05a3035f0ff1c43600e8 against base e71fdab2ab088001f218765ecb5e3b7fabfee11a.

Result: no path-specific actionable finding.

The checked-out commit matches the requested head. The merge base matches the requested base. The diff changes eight paths.

git diff --check passed. bash -n scripts/ci/run_opencode_review_model_pool.sh passed.

The process-group boundary is correct.

  • Each opencode run starts through setsid timeout --kill-after=30s.
  • Early cleanup requires a structured "type":"error" event and a recognized fatal-provider signature.
  • The launcher sends SIGTERM only to the negative attempt process-group ID, -$opencode_pid.
  • The launcher polls for at most 30 seconds.
  • The launcher then sends SIGKILL to the same process group if it remains.
  • The workflow shell and unrelated model attempts are outside this target.
  • The ordinary run timeout remains timeout --kill-after=30s.
  • The export timeout remains separate at timeout --kill-after=15s.

The dependency-review support probe fails closed.

  • It uses --connect-timeout 10 and --max-time 30.
  • It discards the response body with -o /dev/null.
  • It requires successful curl transport completion.
  • It requires exact HTTP 200.
  • It writes supported=true only after both conditions pass.
  • Transport failure or any other HTTP status logs Failing closed and exits with failure.
  • tests/test_dependency_review_support_probe.py extracts the workflow shell body and simulates curl output 200 followed by exit status 18. The test requires failure and rejects supported=true.

The deterministic timeout fixture remains sound. It injects subprocess.TimeoutExpired, so its timeout path does not depend on wall-clock delay or execution of the command payload.

The patch adds no credential expansion, permission change, temporary writer, ref update, reviewer change, approval change, merge action, release action, or publishing action.

All exposed exact-head workflows completed successfully. This includes Security Scan, CodeQL PR, Python Security, SAST Semgrep, Secret Scan, OSV-Scanner PR, Scorecard PR, SBOM Generation, Strix Security Scan, Required OpenCode Review, and Required Noema Review. The exact-head coverage-source-tree and coverage-evidence checks also succeeded.

No unresolved review thread exists.

The accessible required-workflow logs did not contain the claimed numeric test count or explicit 100% statement coverage, branch coverage, and docstring percentages. Those numeric claims are therefore not independently confirmed from the accessible same-head logs.

GitHub reports mergeable: MERGEABLE, but mergeStateStatus: BLOCKED and reviewDecision: REVIEW_REQUIRED. This is a review-governance condition. It is not a code finding.

No files, refs, settings, credentials, approvals, or merge state were modified.

Final read-only exact-head review for 1779da411ef2f4c2f20e05a3035f0ff1c43600e8. All eight current-head security and supply-chain workflows are successful and all actionable threads are resolved. Validate dedicated process-group termination for fatal provider descendants, bounded TERM→KILL cleanup, fail-closed dependency-review support probing that requires both curl exit 0 and HTTP 200, the partial-transfer regression, 100% central statement/branch/docstring evidence, and the eight-file permanent scope. Submit a formal current-head verdict only; do not mutate or merge.

@seonghobae Formal read-only review completed for exact head 1779da411ef2f4c2f20e05a3035f0ff1c43600e8 against base e71fdab2ab088001f218765ecb5e3b7fabfee11a.

Result: no path-specific actionable finding.

The diff changes these eight paths:

  • .github/workflows/security-scan.yml
  • CHANGELOG.md
  • docs/doctoring/dependency-review-support-probe.md
  • docs/doctoring/opencode-process-group-termination.md
  • scripts/ci/run_opencode_review_model_pool.sh
  • tests/test_dependency_review_support_probe.py
  • tests/test_required_workflow_queue_contract.py
  • tests/test_sandboxed_verify.py

git diff --check passed. bash -n scripts/ci/run_opencode_review_model_pool.sh passed.

The OpenCode process-group boundary is correct.

  • Each attempt starts with setsid timeout --kill-after=30s.
  • Early cleanup requires a structured "type":"error" event and a recognized fatal-provider signature.
  • Cleanup sends SIGTERM to the negative attempt process-group ID.
  • Cleanup polls for up to 30 seconds.
  • Cleanup then sends SIGKILL to the same process group if it remains.
  • The workflow shell and other model attempts are outside the target.
  • The ordinary run timeout remains timeout --kill-after=30s.
  • The export timeout remains timeout --kill-after=15s.

The dependency-review support probe fails closed.

  • curl uses --connect-timeout 10 and --max-time 30.
  • The probe discards the response body with -o /dev/null.
  • The probe requires a successful curl exit status.
  • The probe requires exact HTTP 200.
  • Only then does it write supported=true.
  • A transport failure or any other HTTP status exits with failure.
  • tests/test_dependency_review_support_probe.py simulates HTTP 200 followed by curl exit code 18. The test requires failure and rejects supported=true.

The timeout fixture is deterministic. It injects subprocess.TimeoutExpired. It does not wait for a real command timeout or execute the payload.

All exposed exact-head security and supply-chain workflows completed successfully. This includes Security Scan, CodeQL PR, Python Security, SAST Semgrep, Secret Scan, OSV-Scanner PR, Scorecard PR, SBOM Generation, and Strix Security Scan. No unresolved review thread exists.

The current coverage-source-tree and coverage-evidence checks succeeded. However, their logs only delegate PR-head execution to another authenticated workflow. They do not show a test count, statement coverage, branch coverage, or docstring measurement. Therefore, the claimed 100% statement coverage, 100% branch coverage, 100% production docstrings, and complete central test evidence remain inconclusive from accessible exact-head logs.

GitHub reports mergeable: MERGEABLE, mergeStateStatus: BLOCKED, and reviewDecision: REVIEW_REQUIRED. This is a review-governance condition. It is not a code finding.

No files, refs, settings, credentials, approvals, or merge state were modified.

@seonghobae Formal read-only review completed for exact head 1779da411ef2f4c2f20e05a3035f0ff1c43600e8 against base e71fdab2ab088001f218765ecb5e3b7fabfee11a.

Result: no path-specific actionable finding.

The checked-out commit, PR head, and merge base match the requested commit boundary. The diff changes these eight paths:

  • .github/workflows/security-scan.yml
  • CHANGELOG.md
  • docs/doctoring/dependency-review-support-probe.md
  • docs/doctoring/opencode-process-group-termination.md
  • scripts/ci/run_opencode_review_model_pool.sh
  • tests/test_dependency_review_support_probe.py
  • tests/test_required_workflow_queue_contract.py
  • tests/test_sandboxed_verify.py

git diff --check passed. bash -n scripts/ci/run_opencode_review_model_pool.sh passed.

The OpenCode cleanup uses a dedicated session for each attempt:

  • It launches the bounded run with setsid timeout --kill-after=30s.
  • It starts early cleanup only after a structured "type":"error" event matches a recognized fatal-provider signature.
  • It sends SIGTERM to the negative attempt process-group ID.
  • It waits for group disappearance for at most 30 seconds.
  • It then sends SIGKILL to the same process group when needed.
  • It does not target the workflow shell or unrelated model attempts.
  • The ordinary run timeout remains timeout --kill-after=30s.
  • The export timeout remains timeout --kill-after=15s.

The deterministic timeout regression injects subprocess.TimeoutExpired. It does not wait for a real timeout. The command payload does not execute.

The dependency-review support probe fails closed:

  • curl uses --connect-timeout 10 and --max-time 30.
  • The probe discards the response body with -o /dev/null.
  • It requires successful curl completion.
  • It requires exact HTTP 200.
  • It writes supported=true only after both conditions pass.
  • The focused regression simulates HTTP 200 followed by curl exit code 18.
  • That regression requires a nonzero shell result and rejects supported=true.

The doctoring records describe the failure boundary, rollback constraints, and the partial-transfer condition. The setsid(2) reference credits the Linux man-pages project and identifies Linux man-pages 6.18 with the date February 8, 2026.

The patch does not add reviewer changes, provider credential changes, branch-protection changes, ref writers, merge actions, publishing actions, or release actions.

All exposed exact-head workflows completed successfully. This includes Security Scan, CodeQL PR, Python Security, SAST Semgrep, Secret Scan, OSV-Scanner PR, Scorecard PR, SBOM Generation, Strix Security Scan, Required OpenCode Review, and Required Noema Review. No unresolved review thread exists.

The coverage-source-tree and coverage-evidence checks succeeded. Their exposed metadata does not include numeric statement coverage, branch coverage, or docstring results. I therefore cannot independently confirm those numeric values from the inspected same-head evidence.

GitHub reports mergeable: MERGEABLE, mergeStateStatus: BLOCKED, and reviewDecision: REVIEW_REQUIRED. This is a review-governance condition. I did not create a synthetic approval.

No files, refs, settings, credentials, reviews, or merge state were modified.

/oc Review exact current head 1779da411ef2f4c2f20e05a3035f0ff1c43600e8 read-only. All exact-head quality/security checks are terminal success and review threads are resolved. Verify process-group/session termination and bounded SIGTERM/SIGKILL cleanup for fatal provider descendants, ordinary timeout behavior, descriptor/EOF closure, and dependency-review curl exit-status plus HTTP-200 fail-closed semantics. Publish a formal current-head verdict; do not mutate or merge.

@opencode-agent @cwl-noema-review Please independently review exact current head 1779da411ef2f4c2f20e05a3035f0ff1c43600e8 only. All exact-head quality, security, supply-chain Checks are complete and successful and current inline threads are resolved. Verify process-group termination, bounded signal escalation, curl fail-closed dependency-review support detection including HTTP-200 transport failure, no credential/reviewer-chain changes, and no branch-writer or bypass path. Submit formal APPROVE only if this exact head has no blocker; otherwise publish actionable path-specific findings. Predecessor-head reviews are stale.
