Platform
Binding architecture, toolchain, and decision records for the greenfield Flow platform.
These pages summarize material that applies to every service. The canonical, binding spec for architecture questions is still docs/architecture.md at the repository root.
Architecture
Postgres as source of truth, commands and queries, outbox, Cedar, identifiers, and layout.
Toolchain
Go, Postgres, Huma, sqlc, Cedar, Azure Service Bus, and why each was chosen.
Sign-in and authorization
Kratos, Hydra, the identity service, and how web apps and services use them.
Decisions
ADRs: no event sourcing, HTTP/JSON, transactional outbox, and more.
