Build failure notification noise from lint errors in Glitch project alerts

Glitch automatically emails project owners when a build or deployment fails, but the default threshold includes every minor lint error, creating notification noise that hides actionable failures. The Project Settings → Notifications panel can mute alerts for an entire project, yet it provides no granular control to suppress specific error types or severity levels. Webhook alerts are supported for external services, but the documentation lacks a clear example for filtering by error severity. It also remains undocumented whether per-file or per-module notification suppression is possible, leaving developers to filter issues manually.

Because alert behavior may vary between free and paid plans and the interface changes frequently, the exact capabilities are uncertain without direct testing. The goal is to retain alerts for genuine build and deploy failures while eliminating noise from low-severity lint issues.

Does Glitch offer any severity-based filtering for build failure notifications, or is the only control an all-or-nothing project toggle? Is there a supported method to configure webhook payloads so lint errors are ignored while deployment failures still trigger alerts? Are per-file or per-module suppression rules available in any subscription tier?
