# Phase 3 Verification — v0.8 Coverage & Trust Hardening

**Phase**: P03 — Requirements-hygiene gate
**Milestone**: v0.8
**REQ**: REQ-060
**Date**: 2026-08-04
**Result**: ✅ PASS (all 4 layers)

## Layer 1 — Structural ✅

- `go build ./...` PASS
- `go vet ./...` PASS
- `cmd/verify-reqs/main.go` (~180 LOC, stdlib only) compiles + links
- All exports resolve: `verify(roadmapPath, reqsPath) (diff []string, count int, err error)`
- No new dependencies

## Layer 2 — Behavioral ✅

- `go test ./cmd/verify-reqs/...` PASS (7 golden-file tests: clean, multi-drift, default-args, malformed, missing-file, v0.2-substring-tolerant, real-repo regression)
- `make verify-reqs` → exit 0 on the current repo (`✓ 60 requirements consistent with roadmap`)
- T03.5 synthetic drift verification: scratch flip of REQ-053 → `make verify-reqs` exit 1 + `REQ-053: status=Pending, expected=Complete (direction=forward)`; revert → exit 0
- `go test ./...` PASS (all 16 packages)
- Forward + reverse assertions both exercised (golden test `TestVerify_drift` asserts `direction=reverse` for REQ-003)

## Layer 3 — Security ✅

- verify-reqs is a static doc-consistency checker — no network, no secrets, no input injection (markdown is parsed with `regexp` over local files only)
- `.coreci.yml` step runs in the existing `golang:1.25` container (no new image, no new permissions)
- No STRIDE surface added

## Layer 4 — Quality ✅

- Testable core (`verify()` function) + thin `main()` — follows the `cmd/orca/main.go` → `run()` pattern from T01.11
- Golden-file test fixtures cover the substring-tolerant regex regression (v0.2 header variant)
- GRILL condition #4 satisfied: substring-tolerant regex + reverse-direction assertion + scope note (doc-vs-doc only)
- P0 issues: none. P1+ issues: none flagged.

## Requirement Coverage

| REQ | Status | Evidence |
|-----|--------|----------|
| REQ-060 | ✅ Complete | `cmd/verify-reqs` (T03.1) + golden tests (T03.2) + `make verify-reqs` (T03.3) + `.coreci.yml` validate hook (T03.4) + synthetic drift verification (T03.5) |

## GRILL Conditions Check

- **#4 (verify-reqs regex + reverse direction)**: ✅ substring-tolerant regex matches v0.2's `**COMPLETE (merged to main via v0.3)**` header (golden test `TestVerify_v0_2_substring_tolerant`); reverse-direction assertion implemented + tested; scope note documented in the commit + the verification report.

## Lessons

- The two-regex parser (one for REQ rows, one for milestone-complete headers) with substring tolerance is the right shape — a single strict regex would have silently exempted v0.2 (the exact drift the GRILL flagged).
- Refactoring `main()` into a testable `verify()` function made golden-file testing trivial (no subprocess orchestration). This mirrors the T01.11 `main()→run()` pattern and should be the house style for all `cmd/` programs.
