## Notes
- Verified that all fixes from the previous audit (2026-03-31) have been merged and are active. `Sandbox::check` accurately denies paths with directory traversal tokens. `WorkspaceRoot::resolve` properly guards against absolute path replacements. `hash_file` uses buffered incremental hashing instead of allocating the full file into memory.
- `compute_lines_changed` handles string modifications safely for E7.
- Overall code quality is very high. No regressions or unimplemented gaps found.
