- 0 CRITICAL
- 1 WARNING
- 2 SUGGESTION

## Section 1: REQ-by-REQ verification (16/16 COMPLIANT)

| REQ | Status | Code location | Notes |
|-----|--------|---------------|-------|
| REQ-001 AgentRunner + Verdict | COMPLIANT | `internal/llm/runner.go:22-51` | Interface single method `Compare`; Verdict has all 5 fields; 5 error sentinels |
| REQ-002 ClaudeRunner parses Claude CLI | COMPLIANT | `internal/llm/claude.go` | Strips fences via `fenceRE`; parses `.result`; injectable `runCLI` |
| REQ-003 OpenCodeRunner parses NDJSON | COMPLIANT | `internal/llm/opencode.go` | `bufio.Scanner`; extracts `type=="text"` events |
| REQ-004 Runner factory | COMPLIANT | `internal/llm/factory.go:28-49` | "claude"→ClaudeRunner, "opencode"→OpenCodeRunner; empty/unknown error names ENGRAM_AGENT_CLI |
| REQ-005 --semantic flag | COMPLIANT | `cmd/engram/conflicts.go:309,340-341,402-439` | --semantic absent → Phase 3 unchanged; cost prompt + fast-fail; --yes skips prompt |
| REQ-006 --concurrency N (1-20, def 5) | COMPLIANT | `cmd/engram/conflicts.go:310,342-348,376-380` | Range validated up-front |
| REQ-007 --timeout-per-call N (def 60s) | COMPLIANT | `cmd/engram/conflicts.go:311,349-355,435` | `context.WithTimeout` per pair; timeouts → SemanticErrors++ |
| REQ-008 --max-semantic N cap (def 100) | COMPLIANT | `cmd/engram/conflicts.go:313,358-364,436` | Cap at pair collection; sets `result.Capped=true` |
| REQ-009 JudgeBySemantic | COMPLIANT | `internal/store/relations.go:725-810` | UPSERT semantics; `marked_by_kind="system"`, `marked_by_actor="engram"`; not_conflict no-op |
| REQ-010 ScanResult counters | COMPLIANT | `internal/store/relations.go:154-156` | JSON tags `semantic_judged/skipped/errors`; zero-value safe |
| REQ-011 mem_compare MCP tool | COMPLIANT | `internal/mcp/mcp.go:99,747-802,1684-1753` | Schema validated; resolves int IDs to sync_ids; calls JudgeBySemantic |
| REQ-012 per-pair failure isolation | COMPLIANT | `internal/store/relations.go:1361-1407` | panic recover; warn log; SemanticErrors++; scan continues |
| REQ-013 conflict-scan modified | COMPLIANT | `cmd/engram/conflicts.go:300-470` | Phase 3 logic preserved when --semantic absent |
| REQ-014 POST /conflicts/scan semantic params | COMPLIANT | `internal/server/server.go:817-933` | `*int` distinguishes absent from zero; counters always present |
| REQ-015 backwards-compatibility | COMPLIANT | Full test suite | ScanOptions zero-value Semantic=false → Phase 3 path |
| REQ-016 existing MCP tools unaffected | COMPLIANT | Tool count 17→18 verified | mem_compare additive only |

### Build

`go build ./...` → exit 0 (clean)

### Coverage on Phase 4 packages

- internal/llm: 82.1%
- internal/store: 79.2%
- internal/mcp: 93.5%
- internal/server: 57.5% (pre-existing gap; Phase 4 block fully covered)

### Strict TDD compliance

- 73 tests added across 12 test files
- All RED-before-GREEN cycles verified per apply-progress
- 0 failures

### Phase 1/2/3 regression

- Phase 1 (mem_judge, FindCandidates): GREEN
- Phase 2 (cloud sync, sync_apply_deferred): GREEN
- Phase 3 (conflicts scan/list/show/stats/deferred): GREEN

## Section 3: Findings

### CRITICAL

None.

### WARNING

1. **WARNING-1 — Stale tool count in `docs/AGENT-SETUP.md:50`**
   - Reads `(12 agent-facing tools)` while lines 61, 102, 454-458 use `18 tools`. Pre-existing from Phase 1.
   - Non-blocking: does not affect runtime behavior or spec REQs.
   - Suggested fix: change to `14 agent-facing tools`.

### SUGGESTION

1. **SUGGESTION-1 — `internal/server` coverage 57.5%**
   - Below other Phase 4 packages (llm 82.1%, store 79.2%, mcp 93.5%). Most uncovered branches are pre-existing (cloud/auth). Phase 4's semantic block is fully covered.

2. **SUGGESTION-2 — `agentRunnerFactory` indirection is non-obvious**
   - Necessary for store→llm import decoupling. Documented in apply-progress Deviations. A code comment would help future contributors.

## Section 4: Recommendation

**READY_TO_ARCHIVE.**

- 16/16 spec REQs COMPLIANT
- 30/30 tasks complete and verified
- Full `go test ./...` GREEN (20 packages, exit 0)
- Build clean
- 1 WARNING (pre-existing, non-blocking)
- Strict TDD verified
- Zero Phase 1/2/3 regressions

The change is production-ready. The WARNING in AGENT-SETUP.md:50 can be addressed in a follow-up doc PR or inline before archiving.
