Marc-André Bombeck 351e7d1fe0 fix(backup): keep a dump locally only where it survives the container
The image creates DB_BACKUP_DIR owned by the app user, so an install that
runs it without the backups volume could write there, and every nightly and
pre-migration dump landed in the container's own layer. The next update
threw them away while the admin page, the boot line and the readiness card
called them kept on this server.

A dump directory now counts as kept only when it survives the container:
inside a container (Docker, Podman, Kubernetes, a container cgroup or an
overlay root) the directory must sit on a mount of its own that is not a
tmpfs, read from /proc/self/mountinfo with a device-number fallback;
outside one, a writable directory is a disk. Otherwise no dump is written
there: the nightly run uploads off-host only and records not_persistent,
the pre-migration dump is skipped with a warning, the boot line says the
directory is inside the container, the backups page stops promising local
dumps and ignores local-only ledger rows, and readiness fails with no
bucket and notes the bucket-only setup otherwise.

The Unraid template gains a path for the dumps, the Unraid and TrueNAS
pages say why it is needed, and the restore drill first runs the stack
without the volume and checks that nothing is kept or claimed.

prisma/

The database layer. HealthLog runs on PostgreSQL 18 (the compose default) or 16 via Prisma 7. This directory holds the single schema file and the forward-only migration history; the generated client is emitted elsewhere.

Contents

  • schema.prisma — 61 models, one file. cuid() primary keys, snake_case columns via @map(...), encrypted columns mostly suffixed *Encrypted (search the file; there are 24 encrypted column references). The generator client block emits to ../src/generated/prisma (imported as @/generated/prisma).
  • migrations/ — numbered, forward-only SQL migrations (0001_… upward). migration_lock.toml pins the provider to postgresql.

Migration workflow

# author a migration from a schema edit
pnpm dlx prisma migrate dev --name <short_snake_case_name>

# regenerate the client after any schema change
pnpm dlx prisma generate

Number a new migration with the next free prefix. The production entrypoint runs prisma migrate deploy on boot, so every migration must apply cleanly forward — there is no down-migration path. Always include the migration file in the same change as the schema edit.

Conventions

  • Encryption is fail-closed: *Encrypted columns are written through @/lib/crypto (AES-256-GCM, versioned key ids); never store plaintext in an encrypted column. Key rotation is scripts/rotate-encryption-key.ts + docs/ops/encryption-key-rotation.md.
  • The generated client under src/generated/prisma is build output — do not edit it.
  • Schema-touching changes that affect the API surface must regenerate docs/api/openapi.yaml (see ../CLAUDE.md).
