# S03 Roadmap Assessment

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

## Evidence

S03 delivered outline and zoom commands exactly as specified, established the `src/commands/` module pattern, and wired `TreeSitterProvider` through dispatch. 84 tests pass, zero deviations from plan, no new risks surfaced.

## Success Criteria Coverage

All 7 success criteria have remaining owners or are already validated:

- Edit function by name + syntax validation → S05, S06
- Read file structure (outline) → ✅ S03 (validated)
- Zoom to symbol with callers/callees → ✅ S03 (validated)
- Checkpoint/restore workspace → S04
- Undo individual file edit → S04
- JSON stdin/stdout protocol → ✅ S01 (validated)
- npm install binary distribution → S07

## Requirement Coverage

Active M001 requirements remain correctly mapped:

- R004, R005, R006, R010, R011 → S05
- R007, R008 → S04
- R009 → S06
- R012 → S07

No requirement ownership or status changes needed.

## Boundary Contracts

S03's actual outputs match the boundary map:

- `src/commands/outline.rs`, `src/commands/zoom.rs` — produced as specified
- Command handler signature `handle_X(&RawRequest, &dyn LanguageProvider) -> Response` — established as the pattern S04/S05 will follow
- `resolve_symbol()` available on provider for S05's `edit_symbol` — confirmed working

S03→S05 boundary is accurate. S04→S05 boundary (backup/checkpoint stores) is unaffected by S03.

## Risks

- Tree-sitter accuracy risk retired by S02 ✅
- Persistent process reliability retired by S01 ✅
- Cross-compilation deferred to S07 — unchanged
- No new risks from S03

## Next Slice

S04 (Safety & Recovery System) — depends only on S01, no blockers.
