deadfish-verify — Verification Protocol

Order of Operations

Deterministic gate (verify.sh) — always first
LLM criteria fan-out — only if DET passes
Aggregate (build-verdict.py)

verify.sh

bash bin/verify.sh --project-dir <path> --task-file <task.md> --mode pre-commit
bash bin/verify.sh --project-dir <path> --task-file <task.md> --mode post-commit --base-commit <sha>

Env fallback (if flags omitted): VERIFY_PROJECT_DIR, VERIFY_TASK_FILE, VERIFY_MODE, VERIFY_BASE_COMMIT. Modes:

pre-commit: diff working tree vs --base-commit (or HEAD), skips git-clean check.
post-commit (default): diff --base-commit..HEAD, enforces git-clean check. Task ## FILES canonical format:

- path: src/auth/jwt.ts
  action: add
  rationale: new JWT module

Compat accepted: path=src/foo.ts action=add Checks: tests, linter, diff budget (<=3x ESTIMATED_DIFF), scope/blocked files, secrets, git clean (post-commit only). Output: structured JSON. Exit 0 when pass=true; exit non-zero when pass=false.

Criteria Rubric (for LLM-tagged ACs)

Three levels — ALL must pass:

EXISTS: Artifact appears in the diff
SUBSTANTIVE: Real code, not TODO/stub/placeholder
WIRED: Connected into the system (import/export/route/config/DI/CLI)

Bias

False negatives are acceptable. False positives are expensive. If uncertain: FAIL.

Verdict Sentinel

```deadfish:VERDICT
scope: TASK
task_id: auth-P1-T02
verify_sh: PASS
criteria:
  - id: AC-01
    status: PASS
    evidence: "src/auth/jwt.ts exports generateToken, imported in src/auth/index.ts"
  - id: AC-03
    status: FAIL
    evidence: "no error handling for expired tokens"
decision: FAIL
fix_forward:
  - "Add try/catch in jwt.ts:generateToken for TokenExpiredError"
```

Build Verdict Aggregation

echo "$verdicts_json" | python3 bin/build-verdict.py

Output: PASS (all YES) | FAIL (any NO) | NEEDS_HUMAN (parse error)

Track-Level QA (P10)

6 categories: C0 Scope, C1 Docs, C2 Consistency, C3 Architecture, C4 Completeness, C5 Safety. Never set C*=FAIL without ≥1 MAJOR+ finding (R2 rule).
