+# S01 Assessment — Roadmap Reassessment
+
+**Verdict: Roadmap is fine. No changes needed.**
+
+## Success Criteria Coverage
+
+- Secrets manifest with predicted keys and guidance → S01 ✅ (contract), S04 (runtime)
+- Auto-mode pauses for uncollected secrets → S03
+- Guided /gsd flow triggers collection → S03
+- Existing keys silently skipped → S02, S03
+- Summary screen before collection → S02
+- npm run build passes → S04
+- npm run test passes → S04
+
+All criteria have at least one remaining owning slice.
+
+## Risk Retirement
+
+S01 was tagged `risk:medium` for prompt compliance — whether the LLM reliably produces a parseable manifest. The forgiving parser mitigates malformed output, and the prompt instructions are clear. The risk is partially retired (contract side). Full retirement is S04's job (runtime proof).
+
+## Boundary Contract Accuracy
+
+S01's actual output matches the boundary map exactly:
+- `SecretsManifestEntry` and `SecretsManifest` types in `types.ts`
+- `parseSecretsManifest()` and `formatSecretsManifest()` in `files.ts`
+- `secrets-manifest.md` template
+- `secretsOutputPath` wired through `auto.ts` and `guided-flow.ts`
+- Planning prompt instructions in both `plan-milestone.md` and `guided-plan-milestone.md`
+
+No boundary map updates needed.
+
+## Requirement Coverage
+
+- R001, R002, R003: contract-proven (S01) — on track
+- R009: validated (S01) — complete
+- R004, R005, R006, R010: mapped to S02 — unchanged
+- R007, R008: mapped to S03 — unchanged
+- All active requirements have owning slices. Coverage is sound.
+
+## Remaining Slice Ordering
+
+S02 → S03 → S04 dependency chain is correct. No reordering, merging, or splitting needed.
