The SAME pill the home screen carries — above the composer, dashed
'Pick propositions from the map' when empty, count + Clear when picked
— now lives on the /chat/new?mode=practice draft. The draft has no
graph behind it, so the pill opens the standalone ChainTableOverlay
(select mode, controlled selection, Done bar) over the /api/graph
snapshot, fetched lazily on first open. The first send carries the
picks as graphContext: the created session is born WITH its ids-first
context marker (target validation's truth set) instead of pickless —
the same contract as the home screen's practice send. Teach drafts
render no pill; practice with no picks stays lean on the wire.
