0475 and 0480 added their columns with a bare ALTER TABLE, which waits
for its table lock behind every open transaction while every write to
the table queues behind it. Both now run in a DO block with a five
second lock_timeout and carry the boot's retry marker; the effect is
the same and both stay safe to run again.
Neither has shipped in a release. A database that already applied them
is unaffected: prisma migrate deploy and migrate status ignore the
checksum of an applied migration (checked against a database migrated
with the old files), so nothing is re-run and nothing is reported.
The lock-timeout guard now refuses, from 0475 on, any statement that
takes a table lock outside such a block.
A status note whose generation stalled or failed opened a fixed five-minute
negative window, and only the read path honoured it. The ingest
invalidator counted only a stored note as fresh, so every data sync
re-enqueued each note whose last generation had just failed, and the
worker generated it again whatever the window said. With a model that
never answers, every sync bought another round of calls per note.
The window now grows with the generations in a row that ended without a
note (failure_streak, migration 0480): five minutes, doubling per failure,
up to two hours. A written or re-dated note resets it. A failure inside an
open window neither moves nor counts it.
runStatusCompletion waits the window out before any provider work,
whichever path selected the note again (a sync, a warm pass, a queued
job), and the ingest invalidator no longer enqueues a note inside its
window. A derived-score assessment that fails now opens the same window.
The person's own regenerate closes the record's windows first, and saving
the AI provider settings closes them and forgets the provider's health
rows, so a fixed setup does not sit out a pause the old one earned.
The window code moves to status-negative-window.ts; the status parity
golden records that the mood note screened earlier in the same minute is
no longer generated again inside its window.
