isTransientFailure() checks the driver's error code first, and 57014
(statement timeout) is already in its transient set. But the wrapping idiom
across the codebase was `throw new Error(\`Database error: ${err.message}\`)`,
which keeps the prose and drops the code. A retryable timeout therefore
arrived anonymous and resolved to UNKNOWN_ERROR: "Något gick fel. Försök
igen." An agent cannot dispatch on that, so it retried.
On production over 60 days, with the two bot integrations excluded: 1024 real
agent failures, 645 of them UNKNOWN_ERROR across 60 actors and 57 companies.
82 retry streaks of three or more identical failures, 462 wasted repeat calls,
53.1% of all agent error calls sitting inside a streak.
The worst offender traces to one line in core. gnubok_query_journal failed 164
times at a p50 of 8110ms while every other failing tool sat between 1 and
315ms, and its path is fetchEntryLines -> fetchAllRows, where
lib/supabase/fetch-all.ts threw `new Error(error.message)`. That is the
highest-traffic strip point in the repo: 31 callers, every paginated read.
query_journal already had a correct TRANSIENT_ERROR branch offering "retry, or
narrow with date_from/date_to" which could never fire, because by the time it
looked, the code was gone.
fetch-all keeps the driver message verbatim: callers match on the existing
text, and this adds the code rather than rewording anything.
Attaching the code is safe. extractCode() only accepts /^[A-Z_]+$/ and every
SQLSTATE contains digits, so it cannot be mistaken for one of our own stable
codes. There is a test for that, and one asserting the old bare-Error shape
still resolves to UNKNOWN_ERROR so the fix cannot silently regress.
Also stops rendering the literal "undefined" when a driver-level failure
carries no message, which is the string that made these unsearchable.
