🪪 Session-Title Branch Pin

Bug: the prompt-bar title was re-derived from the live git branch every turn. With multiple Claude sessions sharing one working tree, another session's git checkout flips the branch under you — so your title flip-flops and your /rename gets clobbered. The fix pins the title to the session's first-seen branch. Simulate it below.

Event log

How each model decides whether to re-emit the title

turn input	Before → title source	After → title source
buildSessionTitle(branch)	getCachedBranch() — live HEAD	getPinnedBranch() — first-seen
shouldEmitSessionTitle()	computed ≠ last → RE-EMIT	computed == last → stay silent

The pin makes the computed title stable across thrash, so the delta-skip keeps the bar silent and /rename survives. Trade-off: an in-session checkout by this session won't refresh the title (fine for the recommended one-worktree-per-session setup).
