[Bug] Statusline displays stale PR number when worktree reused across branches
Bug Description
Statusline shows a stale PR number when one worktree is reused across branches.
What happened: the statusline kept showing "PR #451" after that PR merged and
I created a new branch (with a new PR) in the same worktree. It misled me twice
— I asked "why is 451 still open?" when it wasn't, and later didn't realize the
session had moved on to #452.
Ground truth at that moment:
cwd .claude/worktrees/<name>
git branch --show-current chore/lanes-probe-is-a-name-list
gh pr view --json number 452 (OPEN)
PR 451 MERGED
Expected: the indicator follows the current branch's PR, or shows nothing.
Repro:
- In a git worktree, create branch A, open PR A, merge it.
- Without leaving the worktree: git checkout -b B, push, open PR B.
- Statusline still shows PR A.
Notes: no statusLine key in my global, local, or project settings, so this is
the built-in indicator rather than a custom script. There's a
~/.claude/gh-pr-status-cache.json but it contained neither PR, so that doesn't
look like the source.
