Two independent ways a tab description could be typed in and silently lost.
1. Session Options modal (deterministic). The Session Name input saves on
blur, and every autosave handler in the modal bails on a null
editingSessionId. closeSessionOptions() cleared that id BEFORE hiding the
modal, and hiding it is what blurs the input, so the save always ran too
late and returned early. Escape and backdrop-click lost the name with no
PUT at all; only the X button worked, because mousedown blurs the input
before the click handler runs. Fix: blur the focused modal field first,
then clear the id. That also covers the auto-compact prompt, which saves
on change and had the same fate.
2. Right-click inline rename (racy). The _inlineRenameActive guard from #81
sits in renderSessionTabs() (the scheduler) and _fullRenderSessionTabs(),
but not in _renderSessionTabsImmediate() (the debounced executor). A
render queued in the ~100ms before the rename opened still fires and the
incremental branch rewrites .tab-name's innerHTML, destroying the input
mid-keystroke: it commits a truncated name, or, if it lands before the
first keystroke, closes the rename so everything typed after goes
nowhere. Fix: guard the executor too. finishRename() re-renders on both
commit and cancel, so a render dropped there is picked back up.
Verified end-to-end against a live server on an isolated instance: all three
modal close paths now persist the name, and the rename input survives a
render mid-typing. Both regression tests were checked to fail with their fix
reverted; the render one was vacuous at first because the synthetic tab sat
on <body> instead of inside #sessionTabs, so it now builds the tab in the
real container.
