### Result
**Review Result: Mergeable**
Blocking Issues: 0. No changes recommended.
The policy optimization is correctly scoped and preserves the repository’s
safety, authorization, compatibility, verification, and review guarantees while
reducing unnecessary instruction loading and repeated workflow execution.
### Evidence
- All seven changed files were reviewed completely against baseline
`eab0040389567f45fee805338ae91e5a73830441`.
- Root policy size decreased from 12,368 to 9,728 bytes, a 21.3% reduction,
and remains below the 13,000-byte limit.
- Mandatory policy-reading estimates decreased by 12.4%–34.0%, depending on
the workflow.
- Git mutation remains explicitly user-authorized and read-only by default.
- Scope freezing, exact-delta inspection, preservation of unattributed
changes, architecture gates, and supported-behavior protection remain explicit.
- Passing verification may be reused only while no relevant write, failure,
scope change, configuration change, or new evidence invalidates it.
- Completion now terminates when the unchanged delta, checks, and review
have passed, preventing redundant loops without weakening required gates.
- Formal Review escalation remains mandatory for public or shared contracts,
security, concurrency, externally visible performance, irreversible work,
last-consumer removal, unresolved evidence, and contract-affecting deletion.
- `git diff --check` passed.
- Harness validation and all 116 harness unit tests passed.
- All 310 source-read traces passed.
- Full semantic stability passed:
- Candidate: 131/155
- V0 baseline: 128/155
- Safety regressions: 0
- Confirmed case regressions: 0
- Changed-contract failures: 0
- Critical regressions: 0
- The validated semantic artifacts match the committed contents of all seven
changed policy sources.
- Root-cause, blast-radius, tests/runtime, and convergence review passes
each found zero new issues.
- The working tree is clean after removal of temporary review artifacts.
### Coverage
- Review type: Code Correctness Review
- Candidate type: Standalone local commit
- Baseline: `eab0040389567f45fee805338ae91e5a73830441`
- Candidate: `2d5f64ef9be4e5e7230c16ea653bbd164d1ab5cb`
- Files reviewed:
- `AGENTS.md`
- `.codex/skills/code-implementation/SKILL.md`
- `.codex/skills/code-implementation/references/rules/non-regression.md`
- `.codex/skills/code-implementation/references/verification.md`
- `.codex/skills/coding-standards/SKILL.md`
- `.codex/context/change-completion.md`
- `.codex/harness/agents/cases.toml`
- Behavior clusters reviewed:
- Root routing, authority, and safety
- Implementation and non-regression routing
- Verification reuse and stale-evidence invalidation
- Coding-standard reference selection
- Completion-loop termination and review escalation
- Semantic canaries and policy bindings
- Unresolved evidence gaps: None
- CI scope: Not reviewed; this is a standalone local policy candidate with
no public PR.
- PR style verification gate: Not applicable because the candidate changes
only Markdown and TOML policy artifacts, with no Java, Maven POM, or
style-configuration changes.
