- Source keys carry the normalised origin of the Paperless-ngx or Papra they came from (source_instance on the document, the alias and the purge ledger; unique NULLS NOT DISTINCT). A key stored without one (v1.39.2 imports) matches any instance of its system, and a lookup without one matches any stored instance. The upload route, the lookup route and the import script accept or send it; backups carry it. - Saving a connection reuses the stored token only for the same origin; a new origin needs the token again (422 tokenRequired). - Document ids are checked against what each system issues (Paperless digits, Papra [A-Za-z0-9_-], never . or ..) before any URL is built; the Papra organization id likewise. - Paperless API 9 filters dates on created__gte / created__lte, in the picker and the script. A search page the local re-check empties reads on, up to five source pages. Tags are read past the first 250. - The import's key pre-check uses the lookup allowance, a failed fetch no longer charges the upload allowance, and one import per key runs at a time under an advisory lock, so a double click downloads once. - Reading and deleting one's own connection works with the documents module off and the operator list unset.
prisma/
The database layer. HealthLog runs PostgreSQL 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_casecolumns via@map(...), encrypted columns mostly suffixed*Encrypted(search the file; there are 24 encrypted column references). Thegenerator clientblock emits to../src/generated/prisma(imported as@/generated/prisma).migrations/— numbered, forward-only SQL migrations (0001_…upward).migration_lock.tomlpins the provider topostgresql.
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:
*Encryptedcolumns are written through@/lib/crypto(AES-256-GCM, versioned key ids); never store plaintext in an encrypted column. Key rotation isscripts/rotate-encryption-key.ts+docs/ops/encryption-key-rotation.md. - The generated client under
src/generated/prismais build output — do not edit it. - Schema-touching changes that affect the API surface must regenerate
docs/api/openapi.yaml(see../CLAUDE.md).
