Normalize base_path before deriving subdir.
On Unix, FilePicker::new preserves .., while git_recency::compute returns repository-relative paths. For /repo/sub/.., strip_prefix produces sub/..; the resulting sub/../ prefix matches no Git path, so all recency scores stay zero. Normalize base_path lexically and add a .. regression test.

resolve_base_branch from a Rust doc comment to a normal // comment, preserving
its existing text and meaning.
- Around line 148-158: Update resolve_base_branch to derive the preferred branch
from the repository’s origin/HEAD symbolic reference instead of the
init.defaultBranch configuration; preserve fallback ordering to main and master
when origin/HEAD is unavailable, and ensure the selected branch is resolved
against the remote HEAD target.
- Line 41: Rename the helper and both of its occurrences from
base_path_witin_repo to base_path_within_repo, including the call in the shown
code, without changing behavior.
- Line 47: Correct the spelling in the comment near the default branch recency
logic by replacing “brach” with “branch”; do not change the surrounding behavior
or code.
In `@crates/fff-core/src/git.rs`:
- Around line 13-23: Update tune_libgit2_for_local_reads to remove the call to
git2::opts::strict_hash_verification(false), while preserving the one-time
initialization and object cache limit configuration.
In `@crates/fff-core/src/shared.rs`:
- Line 394: Update refresh_git_status around picker.apply_git_recency so the
asynchronously captured Git status and relative-path recency are applied only
when the same picker generation or identity is still current after reacquiring
the write lock; discard both results on mismatch, without relying solely on root
or base-path comparisons.

Treat this as a breaking API change. fff-search exposes FilePickerOptions with public fields. Adding required git_recency makes existing downstream struct literals fail to compile. Update supported consumers and publish this in a breaking release.

Set Sort::TIME before seeding the revwalk.
Sort::NONE is arbitrary in git2 0.21.0. The budget can therefore stop before newer commits and produce incorrect recency scores. Add revwalk.set_sorting(git2::Sort::TIME).ok()?; before revwalk.push(head).
