One Skip broke a tester's whole onboarding. The provider named every
tool call "call_0", and the desktop bound each setup card to its
request by call id alone. After the apps card was skipped, every later
card with "call_0" showed that old "Skipped" answer instead of its
picker. Composer text was also saved as a pick, so "hey" became a
plugin and a complaint became the layout.
- The agent renames a tool call whose id is already used earlier in
the session (call_0 -> call_0_d2), before the call is stored or run.
Ids already in history never change, so the prompt cache holds.
- The card's request binding is keyed by session, message and call id.
- Composer text on a card with fixed rows counts as a pick only when it
names a row by id or label. Otherwise setup_choose returns
outcome "typed" with the words in `said`, records no card facts, and
tells the model to reply and send the card again. The settled card
shows the typed words.
