+# Phase 3: Poka-yoke Integration & Fleet Verification
+
+Epic #967. Morning review packet for Hermes harness features.
+
+## Poka-yoke Features Implemented
+
+| Feature | Module | PR | Status |
+|---------|--------|-----|--------|
+| Token budget tracker | agent/token_budget.py | #930 | MERGED |
+| Provider preflight validation | agent/provider_preflight.py | #932 | MERGED |
+| Atomic skill editing | tools/skill_edit_guard.py | #933 | MERGED |
+| Config debt fixes | gateway/config.py | #437 | MERGED |
+| Test collection fixes | tests/acp/conftest.py | #794 | MERGED |
+| Context-faithful prompting | agent/context_faithful.py | #786 | MERGED |
+
+## Fleet Verification
+
+- Unit tests pass on all modules
+- Collection: 11,472 tests, 0 errors (was 6 errors)
+- ACP tests: cleanly skipped when acp extra missing
+- Provider validation: catches missing/short keys
+- Skill editing: atomic with auto-revert
+
+## Next Steps
+
+1. Wire token_budget into run_agent.py conversation loop
+2. Wire provider_preflight into session start
+3. Wire skill_edit_guard into skill_manage tool
+4. Fleet-wide deployment verification
