Fjall classifies every failed deployment into a stable dotted code, such as cfn.permissions or ecs.circuit_breaker. The code appears on the deployment’s detail page on fjall.io, in the CLI’s deploy output, and in the deployments list row title. Each code pairs with a stable title, a per-occurrence detail sentence, the provider’s verbatim reason, and remediation steps. Every code also states fault attribution: whether the failure came from your AWS account’s configuration, from your application’s code, from Fjall’s platform, or could not be attributed automatically.

Unclassified failures

The taxonomy grows

New codes are added as recurring failure shapes earn them. The classification schema is versioned, so stored failures can be reclassified when a shape they match gains its own code.
