# REVIEW — OBPI-0.23.0-02-product-proof-gate

**Reviewer:** spec-reviewer agent
**Date:** 2026-03-28
**Verdict:** PASS

## Promises vs Delivery

| # | Requirement | Met? | Evidence |
|---|------------|------|----------|
| 1 | `check_product_proof(adr_id)` in `quality.py` scanning for operator docs per OBPI | YES | `src/gzkit/quality.py:566` — `check_product_proof()` with three detection mechanisms |
| 2 | `closeout_cmd()` invokes proof check and exits 1 if missing | YES | `src/gzkit/commands/closeout.py:561` — proof gate blocks closeout with clear report |
| 3 | Three proof types: runbook keyword match, command doc existence, docstring AST check | YES | `quality.py:520` (`_check_runbook_proof`), `:528` (`_check_command_doc_proof`), `:543` (`_check_docstring_proof`) |
| 4 | Output: per-OBPI table showing proof type or MISSING | YES | `closeout.py:414` — `_render_product_proof_human()` renders status table |
| 5 | BDD scenario: closeout with and without product proof | YES | `features/closeout_product_proof.feature` — 3 scenarios (blocks missing, allows docstring, JSON output) |

**Promises met:** 5/5

## Documentation Quality

**Assessment:** substantive

Command doc at `docs/user/commands/closeout.md` updated. Implementation evidence references concrete file paths, test counts (29 unit, 3 BDD), and reproducible proof commands.

## Closing Argument Quality

**Assessment:** earned

The closing argument identifies the three detection mechanisms by name, explains the integration into `closeout_cmd()`, and articulates the operator impact (cannot proceed without proof). References actual runtime behavior, not planning intent.

## Concerns (Non-blocking)

1. **ALLOWED PATHS drift (minor).** The brief lists `src/gzkit/cli.py` in ALLOWED PATHS and integration points, but the actual implementation is in `src/gzkit/commands/closeout.py` (post-refactor path). The evidence section correctly identifies the actual file. This is a stale reference from before the CLI was decomposed into `commands/`, not a scope violation.

## Summary

All five requirements are delivered with strong evidence. The product proof gate is a genuine hard blocker in the closeout pipeline with three independent detection mechanisms and 29 unit tests. The ALLOWED PATHS reference to `cli.py` is stale (should be `commands/closeout.py`) but does not affect the delivered functionality.
