- the assistant keeps facts for a trip (remember_for_trip) as a change card,
applied into the user's trip notes; existing expenses can be changed
- change card fields as a few icon chips with the rest folded under Details,
the day band marks only what changes, the week grid as compact tiles
- no map button on receipts of things that have no place on the map
- tests follow the composer's accessible name, the receipt's status icon and
the GL map's container; the hanging stream helper honours an early abort
- Postgres probe: qualified columns in the upsert updates; entities restored
to the generator's output; strict ratchet reads the SDK client as untyped
