## Input recall ownership
Prompt recall has two owners on purpose.
- `packages/ui/src/stores/useInputHistoryStore.ts` owns the persisted source of
truth. It keeps the runtime-scoped global bucket and the runtime + directory
+ session bucket, each capped by the configurable input-history limit. That
setting defaults to 40 entries.
- `state/useMessageHistory.ts` owns only keyboard traversal through whichever
bucket the composer was given. It stashes the current draft on entry and
restores it on the way back out.
- `ChatInput.tsx` owns the recalled-entry presentation. If the user edits a
recalled prompt, the UI may show an overlay state for "this came from
history", but that edit does not rewrite stored history.
Transcript visibility is not part of this contract anymore. Revert markers may
hide older user messages from the chat timeline, but they do not decide what
ArrowUp and ArrowDown can recall.
