glitter: list worktrees git knows about, not just rt's registry - #365
Merged
Merged
Conversation
worktree:list only reads rt's own registry, so a worktree made with a plain `git worktree add` (or GitHub Desktop) never appeared in the mission board's foldout -- not even the one the user was currently standing in. mergeWorktreeTrees joins the registry's rows with listWorktreesAsync's own truth by path: the registry wins where both know a path (it carries the rt name and on-deck state), a git-only path is synthesized with its directory basename and never on-deck, and a failed git listing degrades to the registry rows alone.

Canonicalize paths before merging worktree rows.
git worktree list --porcelain returns canonicalized paths, but registry paths are persisted from join(cfg.root, name) without canonicalization. When cfg.root uses a symlink or non-canonical spelling, the exact lookup misses and emits both the registry row and a synthesized row. Use the repository’s canon helper for both sides of the merge, including the seen check.

What
rt glitter's worktree foldout showed "no matches" for repos that plainly have worktrees, because it was built only from rt's registry. A worktree created with plaingit worktree addwas never provisioned through rt, so it was invisible to the board.Reproduced on
flock:Two symptoms, the second worse than the first. The board claimed a repo had no worktrees while git said otherwise, and it did not list the worktree the user was standing in: the top bar read "Current Worktree: flock" while the foldout below it said no matches.
The same view already read git's truth elsewhere. The branch foldout correctly marks a branch "guarded, checked out in another worktree", because
buildWorktreeGuardMapcallslistWorktreesAsyncdirectly. So one foldout showed git and the other showed the registry, in the same frame.Fix
mergeWorktreeTreesunions the two sources by path, behind a newMissionDeps.listGitWorktreescached inrefresh()alongside the other blocking reads (never frommodel()/push(), which run on every keystroke, matching what the neighbouring deps' comments already require).No "unmanaged" marker, deliberately. A git-only tree shows its directory basename where an rt tree shows its rt-assigned name, which already reads as different at no cost. A real badge would need new wire surface plus Go rendering, which is more than this bug warrants.
Badges needed no change:
joinWorktreeRowsalready falls back toEMPTY_GIT_BADGEfor an unmatched path, andcurrentBadge()already carries a comment anticipating that "a plain, never-registered repo never will" be swept. The codebase expected this case; the worktree list was the one place that had not caught up.Verification
Six new driver tests, written first and confirmed red by reverting the implementation: the union, the canonical checkout appearing when the registry knows nothing, the registry winning a shared path, a git-only row getting a usable name and not claiming on-deck, a null listing leaving registry rows intact, and switching to a git-only worktree.
bunx tsc --noEmitclean;bun test lib/mission141/141;bash scripts/repo-purity.shok.bun test packages539/0 andbun test commands1142/0 on a quiet machine.flock, the repo that exposed the bug. The foldout now lists both worktrees, including the canonical checkout, with badges resolving (✓clean,2↑ahead) for trees rt has never seen.A note on the suite, since it could mislead someone reading CI history: an earlier full-suite run here showed 19 failures. Every one was a uniform 5001ms git-subprocess timeout caused by running the full suite concurrently with per-slice runs and several subagents. Re-run on a quiet machine, the same slices are clean, and
main's own baseline was clean throughout. Not a regression from this change.🤖 Generated with Claude Code
