Current exact state

  • protected base: develop@042b0c70531b229af3acbd0421a2f23098d848b3
  • exact head: acd8a8412475a38a86c2749958b59e589de6d1e6
  • lifecycle: Draft / central dependency-review ownership repair / hosted governance evidence incomplete
  • effective delta: remove repository-local .github/workflows/dependency-review.yml and update the release-governance contract test

This lane removes the duplicate repository-local dependency-review execution while retaining the merge-authoritative dependency-review context through the central Security Scan owner path. The live protected ruleset still requires the dependency-review context; the central owner must therefore produce that exact-head evidence before this deletion can land. Do not reintroduce a local duplicate merely to manufacture a status.

Retained author-side source evidence: release-governance suite 36 passed, actionlint passed, diff check passed, and the current branch-head commit is signature-verified. Those results do not replace hosted current-head evidence.

The live Naruon governance layer currently also requires one approving review, stale-review dismissal, review-thread resolution and last-push approval with no bypass actor. The central solo-maintainer satisfiability defect is tracked at ContextualWisdomLab/.github#772; Naruon remains fail closed rather than self-approving or treating a bot/model as a human.

Keep Draft until the unchanged exact head has the central replacement dependency-review plus every other then-live required check terminal-success, zero valid unresolved findings, and effective governance has a legitimate satisfiable path. No dummy requeue commit, gate weakening, self-approval, bypass, force-push, destructive rebase, or predecessor evidence transfer.

Replace this repo's hand-written dependency-review.yml (harden-runner
step, comment-summary-in-pr: never, moderate severity, multi-branch
trigger) with a thin caller into ContextualWisdomLab/.github's reusable
workflow, preserving this repo's exact original policy. The harden-runner
step and comment_summary_in_pr input this repo needed were added to the
central workflow specifically because of this repo's own original design
(see ContextualWisdomLab/.github#1732) -- this repo is the reason those
two features exist centrally, not just a consumer of an unrelated change.

Drops the redundant job-level permissions: block (workflow-level already
covers it) and the informational "Log dependency review policy" step (no
policy value beyond what the underlying action itself reports).

See ContextualWisdomLab/.github#1724, #1728, #1732 and their
docs/adr/0024-.../docs/doctoring/dependency-review-reusable-workflow-
consolidation.md for the full audit and design rationale.

📝 Walkthrough

Walkthrough

The dependency review job now delegates to a pinned central reusable workflow. It uses moderate severity handling, disables PR comment summaries, and declares read-only permissions. The governance test validates the workflow reference, SHA pinning, and permissions.

Changes

Dependency review workflow

Layer / File(s) Summary
Reusable workflow caller and governance validation
.github/workflows/dependency-review.yml, backend/tests/test_release_governance.py
The local dependency review steps were replaced with a full-SHA-pinned reusable workflow. The workflow sets moderate severity handling, disables PR comment summaries, and documents permission inheritance. The governance test validates the caller and read-only permissions.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 72354

The centralized dependency-review caller is configured with read-only permissions and expected inputs, but its governance test does not fully protect those settings from future drift. Strengthen the test before merge.

Fresh live execution found a real caller-contract defect on exact head 6e7a8d8a947fec1ffdfff15f165b3a171ec2e03e: Dependency Review run 33630975578 resolves .github@5f8e5b2a79e709c4ab1a4179a605d34c458b13a1 but terminates startup_failure before creating any job. This is not runner queue starvation.

The canonical .github owner already reproduced the same failure class in newsdom-api/mightyETL and owns the repair in ContextualWisdomLab/.github#1725: reusable workflows cannot elevate the caller's GITHUB_TOKEN permissions. This thin caller removed Naruon's original workflow-level permission envelope, so the minimal consumer repair is to restore:

permissions:
  contents: read
  pull-requests: read

at caller workflow scope while keeping the immutable central pin, fail_on_severity: moderate, comment_summary_in_pr: never, trigger/concurrency policy, and required published check name. After the caller head changes, discard this startup-failure/predecessor evidence and require a fresh real dependency-review / dependency-review job on the new exact head. Do not work around this with gate weakening, runner churn, or a mutable @main pin.

Comment thread .github/workflows/dependency-review.yml Fixed
seonghobae and others added 2 commits September 3, 2026 10:03
workflow test assertions

Two independently-found real gaps in the migration to the central
reusable dependency-review.yml:

1. This caller had no permissions: block at all (CodeQL: workflow does
   not contain permissions). GitHub reusable workflows cannot elevate
   GITHUB_TOKEN permissions through the call chain, so without this the
   job ran with the repo's broader default token permissions instead of
   the minimal contents/pull-requests read the central workflow needs.
   Added an explicit read-only permissions block matching the other
   consumer repos.

2. test_stepsecurity_remediation_adds_pinned_audit_hardening still
   asserted the OLD standalone workflow's internals (a direct
   dependency-review-action pin, BASE_REF/HEAD_REF env vars, a specific
   step-name split) even though the comment directly above it already
   said dependency-review is centralized and "intentionally not
   duplicated locally" (Devin Review). The migrated file is a thin
   workflow_call caller with none of that -- the assertions were simply
   never updated to match. Replaced them with checks on the caller shape
   that actually matters: it calls the central reusable workflow, pinned
   to a full 40-character commit SHA (not a mutable ref), with the
   read-only permissions block from fix 1.

Full backend suite: 1807 passed, 32 skipped.

Comment thread backend/tests/test_release_governance.py Outdated
CodeRabbit on #1539: the substring/regex checks for
dependency-review.yml's reusable-workflow caller shape pass even if a
write permission is added alongside the read ones, and say nothing
about fail_on_severity or comment_summary_in_pr regressing to a
weaker value. Parse the workflow YAML and assert the exact permissions
mapping and with: mapping instead of scanning for substrings.

Verified the new assertions against the actual file content directly
before committing, then ran the full backend suite with CI's exact
invocation (hash-pinned install, PYTHONWARNINGS=error): 1806 passed,
33 skipped.

The organization-required Security Scan already owns the exact-base/head dependency-review hard gate and check context. Remove the redundant local caller and keep a repository contract that central ownership remains explicit.

Current head acd8a8412475a38a86c2749958b59e589de6d1e6 was revalidated against the live central security-scan.yml: its dependency-review job checks out and verifies the exact PR head, probes exact base/head support fail-closed, runs pinned dependency-review-action v5.0.0 with fail-on-severity: moderate and comment-summary-in-pr: never. Local release-governance tests are 36 passed; actionlint and diff check pass. Organization ruleset detail requires unavailable admin:org, so hosted required-workflow execution remains the merge authority. Pending checks/review are wait states, so the PR is Ready, not merge-authorized.
