K0 ran on the owner's SJ Prio Mastercard on 2026-10-24; the report
docs/spikes/K0-enable-banking.md holds aggregates only. SPEC v0.36 answers
every K0 TODO(spec) of §9.12: D-177 K0's outcome and the owner's
assumptions (partner card, pending->booked, next-day session; verified by
K1's owner steps), D-178 the windowed history fetch (100-row cap, no
continuation key: 30-day windows split at 100 rows), D-179 the transaction
mapping (merchant from remittance_information, booking date else value
date, FEE debits to handle, debtor/CPAN fields never stored), D-180 the
artwork cropped to the card (1313 x 829) and committed for Android and the
web. K plans, prompts/README and HANDOFF follow; K1 to K3 spec text goes
into v0.37.
