# S02 Roadmap Assessment

**Verdict: Roadmap confirmed — no changes needed.**

S02 delivered all four silent failure fixes with 20 targeted tests and 647 total tests passing. R401 validated.

## Success Criteria Coverage

All 8 success criteria have owners:
- 5 criteria proven by S01+S02 (completed)
- 3 criteria owned by S03: `DecisionAction` enum, `member_count` validator, full suite regression gate

## Remaining Slice

S03 (Type Safety & Data Integrity) is unchanged:
- Scope: enum on `RuleDecision.action`, `SubnetGroup` validator, `dict()` fix, subnet dedup fix
- Risk: low (still accurate — no new risks surfaced)
- Dependencies: none (independent, confirmed by S01/S02 having no shared state)
- Requirements: R406, R407 remain active, mapped to S03

## Requirement Coverage

- R401–R405: validated (S01, S02)
- R406, R407: active, S03 owns both
- R501–R504: deferred to M004, unaffected

No boundary map changes. No proof strategy changes. Test count grew to 647 (from 623 baseline) — S03's final regression gate uses this as the new floor.
