# S01 Roadmap Assessment

**Verdict:** Roadmap unchanged. S02 and S03 proceed as planned.

## Coverage Verification

All 8 success criteria have owning slices. S01 retired 3 criteria (stage identity, token tracking, prompt field names). Remaining 5 criteria map cleanly to S02 (silent failures) and S03 (type safety).

## Key Findings

- S01's stage-level error wrapping (D064) does not overlap with S02's 8 bare `except Exception` targets — those are in `rich_output.py`, `excel_rich_output.py`, `registry.py`, and `export/models.py`, not pipeline stages.
- S02/S03 planners should note: `error_code == "PIPELINE_STAGE_FAILED"` is no longer reachable for stage errors (stage-level wrapping catches first). This doesn't affect S02/S03 scope — just test expectations if they touch runner error paths.
- No new risks, no new requirements, no deferred captures.

## Requirement Coverage

- R401 (active) → S02 primary — unchanged
- R405 (validated by S01) → S02 supporting for orphaned decisions logging — unchanged
- R406 (active) → S03 primary — unchanged
- R407 (active) → S03 primary — unchanged
- R402, R403, R404 validated by S01 — no further action needed
