Warning
An ingest 401/403 is retried every tick with no backoff, unlike billing
F2 · Warning · correctness
Only status === 402 gets a hold. A 401/403 refusal — isIngestRefusal in upstream-body.ts covers these, and CloudflareAnalyticsService.ts:199 holds them with PLAN_BLOCKED_BACKOFF_MS — falls through to NOT_STORED ("Maple retries in 5 minutes. Nothing to do."). The watermark is not advanced, so the connector is due again on the next tick and re-queries Google's 46 Monitoring calls per connector for a window it can never store, while the customer is told nothing is wrong.
Classify the status with `isIngestRefusal(error.status)` and pass a short `holdUntilMs` for the non-billing refusal, as the Cloudflare poller does, instead of reporting it as a transient storage failure.

In `packages/backend/src/services/integrations/GcpMetricsService.ts:523-526`: An ingest 401/403 is retried every tick with no backoff, unlike billing.
Only `status === 402` gets a hold. A 401/403 refusal — `isIngestRefusal` in `upstream-body.ts` covers these, and `CloudflareAnalyticsService.ts:199` holds them with `PLAN_BLOCKED_BACKOFF_MS` — falls through to `NOT_STORED` ("Maple retries in 5 minutes.

The watermark is not advanced, so the connector is due again on the next tick and re-queries Google's 46 Monitoring calls per connector for a window it can never store, while the customer is told nothing is wrong.
Suggested fix: Classify the status with `isIngestRefusal(error.status)` and pass a short `holdUntilMs` for the non-billing refusal, as the Cloudflare poller does, instead of reporting it as a transient storage failure.
Verify the problem exists at that location before changing it, and keep the fix to those lines.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Classify every billing sentence as BILLING_DISABLED before you check for a disabled service.
reasonFromMessage maps a message to BILLING_DISABLED only when it contains the exact phrase "requires billing". Any other message that contains "is disabled" maps to SERVICE_DISABLED.
Some Google refusals about billing use different wording. One example is "The billing account for the owning project is disabled in state closed." If a 403 like that arrives without an ErrorInfo detail, the code reports SERVICE_DISABLED. The connection then tells the customer to run the setup script again to switch on an API. That does not fix the cause, which is the billing account.
Check for any mention of billing before the SERVICE_DISABLED check.

Google Cloud metrics and resource poller: PR C of the GCP integration, on top of #1321.
Every 5 minutes the alerting Worker reads a curated set of Cloud Monitoring metrics for each connector that has
metrics_enabledand ships them through the ingest gateway as OTLP. Hourly it syncs the connector's resource inventory (its projects, and the resources behind the metrics) into Postgres. A connector is one scope (a project, a folder or an organization) and both Google APIs are queried at that scope, so a poll costs about one call per curated metric however many projects the scope holds.packages/domain/src/gcp-metrics.ts(@maple/domain/gcp-metrics): the curated metric table and asset type list.
