Each month of the million-row seed runs in an interactive transaction with
an explicit timeout. The batch form ran under Prisma's 5 s default and a
month took 9.9 s at a high load average, expiring the transaction before
the heap assertion ran.
The heap test for the pulse day-mean rebuild wrote its million readings in
one INSERT ... SELECT, which outran the 60-second statement timeout on CI's
shared Postgres. The fixture is now written a month per statement, each in
its own transaction with the timeout lifted for that transaction only, and
ANALYZE the same way; the code under test keeps the timeout, and the
production-heap assertions are unchanged. With the timeout at 4 seconds the
old seed is cancelled with 57014 and the new one passes.
The rebuild after apply now writes its state beside the dry run
(queued, running, done with counts, failed); a run left queued or
running without a job reads as failed. The card shows it and offers a
new rebuild after a failure, which the route accepts once the method is
applied, without a new dry run.
