# Summary
- Fix resume/fork config rebuild so cwd changes inside the TUI produce a
fully rebuilt Config (trust/approval/sandbox) instead of mutating only
the cwd.
- Preserve `--add-dir` behavior across resume/fork by normalizing
relative roots to absolute paths once (based on the original cwd).
- Prefer latest `TurnContext.cwd` for resume/fork prompts but fall back
to `SessionMeta.cwd` if the latest cwd no longer exists.
- Align resume/fork selection handling and ensure UI config matches the
resumed thread config.
- Fix Windows test TOML path escaping in trust-level test.
# Details
- Rebuild Config via `ConfigBuilder` when resuming into a different cwd;
carry forward runtime approval/sandbox overrides.
- Add `normalize_harness_overrides_for_cwd` to resolve relative
`additional_writable_roots` against the initial cwd before reuse.
- Guard `read_session_cwd` with filesystem existence check for the
latest `TurnContext.cwd`.
- Update naming/flow around cwd comparison and prompt selection.
