# Multi-LLM Review — Final Outcome (Upstream Detector Fix)

**Review Target**: The upstream CLI change detector enhancement (bidirectional help surface probe + `--probe-installed` support in live scanner + snapshot augmentation + docs).

**Process**: 
- Round 1: Parallel reviews by Claude, Codex, Gemini, Grok, Mistral (all with fresh mcp_managed + full MCP tool access, 90s+ polling compliance, strict "inspect with tools yourself + quote source" instructions, "UNCONDITIONAL APPROVED or concrete blocker" verdict requirement).
- Blocker found by Claude: new `prefer-const` ESLint error at `src/upstream-contracts.ts:1110` (`let name` in new `extractDiscoveredFlags`).
- Fix applied + verified (eslint clean, gates/tests pass).
- Round 2: Fresh permissions + focused re-inspection of the one-line delta only + evidence addendum.

**Round 2 Verdicts (all after direct tool inspection of the fix)**:
- **Claude** (Opus 4.8): UNCONDITIONAL APPROVED  
  Explicitly re-read the exact line, re-ran lint (`NO prefer-const violations`), confirmed all prior claims + invariants remain accurate. "The one concrete blocker I raised in Round 1 is resolved, and nothing new was introduced."
- **Grok**: UNCONDITIONAL APPROVED  
  Re-inspected the delta, re-ran eslint (clean) and tests (12/12), confirmed no side effects and all claims hold.
- **Mistral**: UNCONDITIONAL APPROVED
- **Gemini**: UNCONDITIONAL APPROVED
- **Codex**: UNCONDITIONAL APPROVED (fix verified)

**Final State**:
- All 5 reviewers gave **UNCONDITIONAL APPROVED** in Round 2.
- The only issue raised across both rounds (the lint error) was fixed with a one-character change that has been independently verified by the reviewer who found it.
- No remaining concrete blockers.
- Full audit trail exists (job IDs, approval records with fresh mcp_managed grants each round, saved outputs, Verification Report + evidence addenda, minimal diffs).

**Conclusion**: The detector fix (including the lint correction) has passed rigorous, evidence-based, multi-LLM review with unanimous unconditional approval from Claude, Codex, Gemini, Grok, and Mistral after they inspected the actual code and artifacts with their tools.

**Key Artifacts**:
- Verification Report: `docs/upstream/reviews/detector-fix-verification-report.md`
- Round 2 Evidence: `/tmp/detector-fix-round2-evidence.md`
- Launch metadata (Round 1 & 2): `/tmp/detector-review-round-*-launch.json`
- All job results persisted in the session MCP call logs.

Review complete — success.
