# S03 Post-Slice Assessment

**Verdict: Roadmap holds. No changes needed.**

## Risk Retirement

S03 retired the "LLM context window limits" risk via the pre-summarizer (D049) — 600 flows compress to ~2-3K tokens instead of ~40K. Mechanism proven by unit tests. Full validation with real LLM deferred to S05 UAT, which is the right place for it.

## Success Criteria Coverage

All 11 success criteria have at least one remaining owning slice:

- Criteria 1-2 (CLI commands, Rich/JSON output) → S05
- Criteria 3-5 (xlsx/pdf export, custom template) → S04, S05
- Criteria 6-9, 11 → already validated by S01-S03
- Criterion 10 (token usage footer) → S05

No gaps.

## Boundary Contracts

S03→S04 contract (`ExcelPipelineState` with decisions, proposals, risk classifications) matches what was built. S03→S05 contract (pipeline runner + output formatters) confirmed ready. S04→S05 boundary (export functions) unchanged.

## Requirement Coverage

- R109, R110, R111 → S04 (active, on track)
- R108 → S05 (active, on track)
- No new requirements surfaced. No invalidations.

## Remaining Proof Strategy

- PDF quality → retire in S04 (unchanged)
- All other risks retired.
