Reference
The developer-trust layer: the CLI, what's configurable (and what deliberately isn't), integration surfaces, and error semantics. For per-endpoint detail, see the API reference section.
CLI
Every surfil command, with honest gaps where flags aren't finalized.
Configuration
What you can configure, and the invariants that aren't settings.
Webhooks
The one inbound webhook today, and what doesn't exist yet.
Errors
Status codes, safe retries, and why 402 never writes.
SDK
There's no SDK yet - use the CLI or the REST API directly.
FAQ
Short answers to the questions people actually ask.
