Reference

Lookup pages generated from the code, so they cannot drift from it: CI regenerates them (go run ./cmd/docgen -check) and fails when a committed page differs. To change one, change its source and run make docs-gen.

Page	Source	Contents
Configuration keys	internal/config	Every YAML key with its environment variable, type, default and description
Metrics	registered Prometheus collectors	Name, type, labels and help of every metric served on /metrics
CLI commands	oa help	Every oa command with its usage
REST API	internal/api/openapi.json	Every endpoint per tag: parameters, request bodies, responses and schemas

How-to pages that explain behaviour, with prose and examples: configuration, monitoring, CLI and REST API.
