Reference

Configuration, data models, dependencies, and the feature-flag catalogue. The user-facing reference docs live in docs/.

Topic	Page	Source of truth
Configuration file schema	Configuration	config/config.go, docs/configuration/configuration.md
On-disk + wire data formats	Data models	tsdb/, prompb/
Third-party dependencies	Dependencies	go.mod, web/ui/mantine-ui/package.json
Feature flag catalogue	Feature flags	docs/feature_flags.md, util/features/

The CLI flag list is generated by make cli-documentation into docs/command-line/prometheus.md and docs/command-line/promtool.md and is the authoritative reference for runtime knobs.
