Code Review

Code Review

Owns: read-only review findings for one frozen scope. It never edits files, runs a quality loop, produces a Verification Record, decides the final claim ceiling, or mutates Git/provider state.

Use the semantic vocabulary and required fields from the canonical Verification Record. Flag missing or contradictory inputs; do not reconstruct a second evidence/gate policy.

Inputs

Accept one acquisition route:

• Runner handoff: frozen diff, CandidateRef, normalized Ticket Envelope, acceptance criteria, decisions, baseline, observed evidence, and draft record when one exists.
• Standalone acquisition: acquire a PR, commit, local diff, or user-requested scope read-only; record its observed head/commit/worktree identity, request constraints, relevant repository rules, and available baseline/evidence.

Do not parse Markdown to infer a Ticket Envelope. If standalone context has no normalized ticket, review against the explicit request and repository contract. If the diff changes, return stale-candidate and stop.

Volatile intake bound

• max_volatile_bytes: 107656 normalized UTF-8 bytes per invocation. This is the observed 96,393-byte candidate-diff high-water mark plus maxima of 2,380 bytes for the ticket body, 4,459 for the implementation handoff, and 4,424 for simplification. The corpus is the run's TK-01/TK-02/TK-05/TK-07/TK-08 normalized git diff --no-ext-diff --no-color observations, its nine ticket bodies, and compact leaf results.
• max_single_output_bytes: 32596, the observed TK-02 executable-code candidate diff.

Count every diff, raw file slice, pasted handoff, evidence body, and tool result after CRLF or lone-CR normalization to LF. Acquire the expected manifest first; truncate command output before it enters context and continue larger diffs by file or hunk. Prefer path plus SHA-256 references over pasted artifacts, loading referenced content only when a review axis requires it. If the next required read would exceed a cap, return a schema-3 partial result with exact inspected/remaining scope and budget-exhausted; do not skip scope or downgrade a finding to fit the bound.

Bounded runner handoff

When the runner supplies a schema-3 bounded LeafContext, treat its CandidateRef, canonical phase contract, expected file manifest, prior inspection, remaining scope, and resource limits as the authoritative continuation boundary. Do not rediscover already-inspected immutable scope for the same CandidateRef.

End every runner-owned review turn with one schema-3 result, including timeout, interruption, or resource exhaustion. Persist the exact CandidateRef and review phase contract, ordered expected/inspected/remaining files, commands, findings, current phase, canonical remaining-phase suffix, and a non-empty stop reason for partial results.

Include normalized schema-3 execution from the observed route. A shared-context or unknown isolation is not independent; report that limitation instead of upgrading it.

A complete review must reach handoff-ready, inspect the declared scope, and return a validated structured finding list. A partial result is usable continuation state but never a pass. A real finding may return the pipeline to implementation and consume a quality failure; timeout, interruption, and resource exhaustion do not. CandidateRef drift invalidates the handoff.

Review axes

Review each axis separately and report only evidence-backed findings:

1. Standards and maintainability — project conventions, clarity, accidental complexity, unsafe error handling, security, data integrity, and unrelated scope.
2. Ticket acceptance — every criterion has a concrete implementation path and observable check; non-goals remain untouched.
3. Semantic regression — externally meaningful behavior is preserved or explicitly authorized. Compare changed boundaries and invariants to the supplied baseline.
4. Causal coverage — tests/evidence exercise the changed mechanism, not merely an adjacent success path. Identify mocked or simulated boundaries explicitly.
5. Claim safety — wording does not exceed the evidence and open gates represented in the canonical record.

Inspect raw files and diffs rather than trusting summaries. Do not call verification-audit; the caller supplies findings to its single audit pass.

Finding format

Sort by severity:

[blocker|should-fix|nit] path:line - problem and impact. Suggested fix.

• blocker: correctness, security, data loss, ticket failure, missing causal coverage, or a material unsupported claim.
• should-fix: meaningful maintainability or non-critical coverage problem.
• nit: optional polish only.

For every finding, name the violated acceptance criterion, invariant, boundary item, or repository rule when available. If no finding exists, say so and list residual evidence limits. A standalone output is a read-only draft; it cannot claim ticket completion or release. Never report PASS for a CandidateRef or standalone scope you did not inspect.
