Shipping

  • All work lands through a pull request. Deploys happen on merge.
  • Database changes are SQL migrations in supabase/migrations/. A migration must be applied to the database when its PR merges, not later.
  • Work is tracked in Linear, in the Cellpath MVP: North Star project.

Where the docs are

  • docs/README.md in the main repo: the map of all engineering docs
  • docs/substrate/: how to add a new domain module
  • docs/decisions/: architecture decision records (ADRs)
