# S05 Roadmap Assessment

**Verdict: Roadmap unchanged.**

## Risk Retirement

S05 retired its medium risk — three-layer editing with auto-backup, syntax validation, and disambiguation all proven across 133 tests. No new risks surfaced.

## Success Criteria Coverage

All 7 success criteria have remaining owners:

- Agent can edit a function by name through OpenCode and get syntax validation feedback → S06
- Agent can read a file's structure (outline) in one call → S06
- Agent can zoom to a single symbol and see what calls it and what it calls → S06
- Agent can checkpoint workspace state, make experimental changes, and restore → S06
- Agent can undo an individual file edit in one call → S06
- All content flows through JSON stdin/stdout — zero shell escaping errors → validated (S01–S05)
- Binary installs via `npm install @aft/core` on macOS/Linux/Windows → S07

## Requirement Coverage

- R001–R008, R010–R011, R032: validated through S01–S05
- R009 (OpenCode plugin bridge): active, owned by S06
- R012 (Binary distribution): active, owned by S07
- R031 (LSP-aware architecture): partially validated (S01), full validation deferred to M004/S03
- R034 (Web-first priority): active, grammars shipped in S02, constraint holds

No requirement ownership changes needed. No requirements invalidated or re-scoped.

## Boundary Contracts

S05 → S06 boundary accurate: all four mutation commands (write, edit_symbol, edit_match, batch) plus shared edit engine match the boundary map's "Produces" section. Integration tests in `tests/integration/edit_test.rs` serve as authoritative request/response shapes for Zod schema generation.

## Remaining Slices

- **S06: OpenCode Plugin Bridge** — no changes. All upstream commands now exist.
- **S07: Binary Distribution Pipeline** — no changes. Depends only on S06 output.
