The 2026-07-17 20:23 postgres blip left the live loop writing zero events for
hours: emit() executed on a RAW cursor, bypassing PgConnection._run's
reconnect. cursor() doesn't round-trip so the dead conn went unnoticed until
the raw execute failed with no retry, and self._conn was never rebuilt.
Routing emit through the facade execute() wraps the round-trip in _run, so a
DB blip reconnects on the next write instead of running blind. 2 reconnect
tests + 34 storage tests green. (Deeper 'halt trading when persistently
unable to write' safety guard queued separately.)
