Same-day settlement visibility plus maximal data capture from the
reporting feed. The handler gains an allowlisted endpoint parameter
(EventBridge passes {"endpoint":"current-day"} on a new 16/19/22 UTC
weekday rule; the 9am previous-day sweep is unchanged and remains
authoritative). Every response's exact bytes archive to a new
Retain-protected bucket before classification, so the feed is
replayable and auditable even across parser changes. Summary rows
become per-date boa_balance# snapshots (latest-wins on run_at, no
TTL) instead of being discarded. The staleness sweep is gated to
previous-day runs so intraday runs don't re-alert the backlog three
times a day. History events carry a via:<endpoint> audit tag outside
the replay-idempotence identity. Fixtures are sanitized real API
captures; classification histograms assert against live-verified
counts.
