bump_fee (tx/broadcast.py) used to overwrite PendingTransaction.
broadcast_at on every fee bump, but reconcile.py's abandon-after-N-
hours grace period is measured from that same column. A transaction
successfully bumped every rbf_timeout_seconds (900s by default) but
never mined reset that clock before it could ever reach the 6-hour
abandon window, so it was never abandoned: its UTXOs never returned to
the user, and if it was a bet the round stayed in "closing"
indefinitely.
PendingTransaction gains a last_broadcast_at column (migration
861e76aaf34c, backfilled from broadcast_at for existing rows before
the NOT NULL constraint is applied). broadcast_at is now never
rewritten after creation, so reconcile.py's _is_due keeps measuring
from the first broadcast unchanged. bump_fee updates last_broadcast_at
instead, and should_bump now reads last_broadcast_at rather than
broadcast_at — correct, since whether another bump is due should reset
after every bump, unlike the reconciler's abandon check, which must
not.
BUGS.md moves B-27 to "Previously fixed" with the fix description; the
suite grows from 148 to 151 tests, including a direct proof that a tx
bumped a minute ago but first broadcast 7 hours ago still gets
abandoned.
