Backend

The API is a NestJS application with these currently implemented modules:

health
users
security
auth
journal
diary
notes
goals
notifications
analysis
mirror
growth
memory
search
governance

The runtime path still uses in-memory services, but the module boundaries now match the intended product shape. The backend already exposes real endpoints for:

capture domains: journal, diary, notes
execution domains: goals, reminders/preferences
AI workflow domains: analysis, mirror, growth, quantum-lens via analysis, memory and search
platform trust domains: auth, security, governance

Prisma currently serves as the persistence contract and next migration target. The next backend step is moving selected services from in-memory storage to Prisma repositories without changing their public controller surface.
