Two additive columns on integration_statuses driving B4 + B7:
- consecutive_failures_by_kind (jsonb) — bucketed counter
{ transient, reauth_required, persistent } so a transient hiccup
followed by a persistent failure no longer resets the persistent
streak counter. The single-column consecutive_failures stays for
one release as a fallback; the alert ladder reads Math.max across
buckets for backward compatibility.
- persistent_failure_started_at (timestamp) — start of the current
persistent failure streak. Once >24h elapse with the persistent
bucket still non-zero, the status writer flips state to 'parked'.
The state column stays free-form; 'parked' is recognised at the
application layer. Existing rows have NULL in both new columns and
are back-filled on the next write.
