The signup → Attio sync (`attio.server.ts` `#assert`) logged every
non-2xx response at `error` level and threw the same way regardless of
status. Transient upstream failures (5xx/429) are retried by the common
worker and self-heal, so treating them as errors created false alerts
for something that isn't actually a bug.
Now `#assert` splits the two cases:
- **5xx / 429** — Logged at `warn` and thrown with `logLevel: "warn"`,
so they continue to be retried but don't raise error-level alerts. This
reuses the same pattern the worker already honors
(`directorySyncEffects`).
- **4xx** — Unchanged: logged at `error` and thrown, so genuine
integration bugs (schema, permissions, auth, etc.) remain visible.
There is no behavior change to retries or the signup flow. This is a
server-only change.
