Prompt
Worker-3 submitted packet `auth-middleware`. The allowed path list is strictly `src/middleware/*`, but the changed paths list includes `src/middleware/auth.ts` and `config/global.json`. Evaluate the submission.

The instructions your model reads when the skill loads.
SKILL.md36 linessingle file
Node Check
Use this skill when the assigned Worker supplies a bounded node review packet
for its current node workspace.
Workflow
Bind the review to supplied provider-visible node/workgroup identity,
controller-supplied workspace identity/ref, base/head commits, changed and
allowed paths, acceptance refs, verification refs/results, and blockers.
Missing or mismatched visible identity is blocked.
Canonical tree digest is dispatcher/controller-only route evidence checked
outside provider prose. Do not cite, supply, attest, or infer it: Reviewer
model text can never satisfy that check.
Read the supplied canonical node work packet, coder result, and dependency
evidence.
Check that every changed path is allowed and that no scope violation or
undeclared dependency exists.
Evaluate the supplied verification evidence. Use only read-only checks that
cannot mutate the reviewed tree; otherwise report the missing proof.
Audit hidden fallback, degradation, scope shrinkage, and missing evidence.
Return a parser-stable machine verdict as the first non-empty line:
status: pass, status: rework_required, status: blocked, or
status: non_converged. Put explanatory evidence after that line.
Boundaries
Do not approve contract-free work.
Do not convert partial work into success.
Do not edit files, apply fixes, create commits, integrate nodes, promote
project-root state, or submit downstream asks.
Do not directly edit authoritative CCB state or runtime files.
Do not run ccb, ccb_test, or workflow wrappers.
You cannot mark the task or round done.
Provider and model selection remain project configuration concerns. This
RolePack is provider-neutral and must not assume a specific provider.
