Add the shared contract the reasoning release builds on, with no change to how a turn runs today. - Schema: operator reasoning controls on app_settings (0376), the encrypted trail text on coach_messages (0377), and source, last_used_at and source_message_id on coach_facts (0378). - Provider contract: CompletionParams.reasoning and onReasoning, CompletionResult.reasoning and providerState, AiMessage.providerState. - Reasoning levels, thinking budgets and the background-job table in src/lib/ai/reasoning/levels.ts; coachPrefsJson.reasoning, absent meaning medium, salvaged field by field like every other pref. - Stream: activity, memoryNote and planProposal frames, done.stop and done.withheldResults, result.interim, a compare chart kind, eight table refs, three more clarification kinds with an assumed choice, the change_assumption chip, and assumptions, activity, stop, memoryNote and planProposal on the provenance. Zod mirror, type parity and the native-client key rule cover every new frame. - Chat request: memoryDecision and planDecision, parsed and not yet acted on. - Stub contracts for the memory functions and the activity recorder, inert until their implementations land. - Backup, restore and rotation carry the new columns; a fact's message reference is resolved against the restored messages like its conversation reference. - Message keys for the trail, memory, plans, assumptions, replies, interim tables, comparison charts and reasoning settings in all seven locales, each reachable from a catalog and checked both ways.
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).
