# S01 Post-Slice Assessment

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

## Risk Retirement

- **Import rewiring completeness** — retired. 5+ consumer files rewired correctly including aliased imports, verified by 9 integration tests through binary protocol.
- **Relative path computation** — retired. 19 unit tests cover path computation across different directory depths. macOS canonicalization edge case (D111) discovered and fixed during integration testing.

## Success Criterion Coverage

- Move symbol with import rewiring → S01 ✅ (complete)
- Extract function with free variable inference → S02 (unchanged)
- Inline symbol with scope conflict detection → S02 (unchanged)
- LSP-enhanced disambiguation → S03 (unchanged)

All criteria have remaining owners. No gaps.

## Boundary Map Accuracy

S01 produced exactly what the boundary map specified:
- `move_symbol` handler following `handle_*(req, ctx)` pattern ✅
- Relative path computation utility ✅
- Multi-file mutation coordination with checkpoint + sequential `write_format_validate` ✅
- Plugin tool `aft_move_symbol` with Zod schema in `refactoring.ts` ✅

S02 and S03 consumption contracts remain valid.

## Requirement Coverage

- R028 (move symbol) — validated by S01, 28 Rust tests + plugin round-trip
- R029 (extract function) — still active, owned by S02
- R030 (inline symbol) — still active, owned by S02
- R031 (LSP-aware architecture) — still active, completing in S03
- R033 (LSP integration) — still active, owned by S03

No requirement ownership or status changes needed.

## Assumptions That Changed

- `callers_of` returns relative paths, not absolute — fixed in S01 handler, no downstream impact on S02/S03.
- macOS `/var` vs `/private/var` canonicalization — fixed via D111, no downstream impact.
- Neither changes the remaining slice designs.

## New Risks

None surfaced.
