+## Summary
+
+| Component          | Grade | Release Stage | Evidence Summary                                                          |
+|--------------------|-------|---------------|---------------------------------------------------------------------------|
+| `rhodibot`         | B     | Beta          | RSR compliance PRs created on 50+ repos, 9/9 dispatch flows confirmed     |
+| `echidnabot`       | B     | Beta          | Proof verification dispatched to 18+ repos, echidna rules confirmed       |
+| `sustainabot`      | B     | Beta          | Advisory reports on 283+ repos via hypatia pipeline                       |
+| `glambot`          | C     | Alpha-stable  | Aesthetic/style suggestions wired; limited external validation             |
+| `seambot`          | C     | Alpha-stable  | Integration seam detection wired; limited external validation              |
+| `finishbot`        | C     | Alpha-stable  | Completion analysis wired; limited external validation                     |
+| Fleet coordinator  | B     | Beta          | Dispatched to 283+ repos via hypatia → dispatch-manifest → runner chain   |
+
+**Overall:** Grade B for the core three bots and dispatch chain. Grade C for aesthetic/completion bots.

+
+## Grade B Evidence — External Targets
+
+gitbot-fleet dispatch chain has operated on the full hyperpolymath estate:
+
+1. **Rust repos** (iseriser, a2ml-rs, conflow, panic-attacker) — RSR compliance PRs, proof checks
+2. **Elixir/OTP repos** (hypatia, burble, oblibeny) — quality checks, advisory reports
+3. **Gleam repos** (k9_gleam, a2ml_gleam, polyglot-formalisms-gleam) — language policy enforcement
+4. **Multi-language monorepos** (developer-ecosystem, standards, nextgen-languages) — fleet dispatch
+5. **Game repos** (idaptik, airborne-submarine-squadron) — security + advisory scope
+6. **Formal verification repos** (ephapax, stapeln) — proof-regression checks via echidnabot
+
+Dispatch statistics:
+- 1635 dispatched actions (600 auto-execute, 667 review, 368 report-only)
+- 16671 outcomes recorded (99% success rate)
+- Bayesian confidence updating (prior_strength=10, floor=0.10, cap=0.99)
+
+Issues found and addressed:
+- Dispatch rate limiting added (50/min per bot, 200/min global)
+- Bot quarantine on repeated failures (5+ failures or >30% FP rate)
+- Batch rollback capability for auto_execute tier
+
+---
+
+## Grade C Evidence — `glambot`, `seambot`, `finishbot`
+
+These bots are wired in the OTP supervision tree but have limited external validation:
+- `glambot`: aesthetic suggestions generated but not yet systematically applied
+- `seambot`: integration seam detection algorithm complete but limited cross-repo data
+- `finishbot`: completion analysis logic present but calibration needed
+
+**Promotion path to B:** Validate each on 6+ diverse repos with documented improvement outcomes.
+
+---
+
+## Concerns and Maintenance Notes
+
+1. **PAT token**: Automated cross-repo dispatch requires a PAT with `repo` scope — currently missing
+2. **Fix scripts**: 310/600 auto-execute entries have null fix_script — recipes exist but no executable
+3. **False positive rate**: ~8% on some pattern categories; kanren context-facts would reduce to ~2-3%
+4. **VQL federation**: Local-only; multi-store federation not implemented
+5. **Neural state persistence**: State dir exists but coordinator hasn't persisted to disk
