Two related AI-infrastructure hardenings landing together because both
touch the same nutriphi/planta route definitions:
═══ 1. Wire-format schema versioning ═══
Adds AI_SCHEMA_VERSION + AiResponseEnvelope<T> in @mana/shared-types so
every AI structured-output endpoint speaks a single envelope dialect:
{ schemaVersion: '1', data: <validated object> }
Backend wraps via a small `envelope()` helper in each module's routes.ts;
frontend api.ts unwraps via `unwrapEnvelope<T>()` which throws an
AiSchemaVersionMismatchError if the server returns a version this
client wasn't compiled against.
Why this matters before launch:
- Catches stale-cache scenarios immediately ("client v1 talking to
server v2") with an actionable error in the network panel, not a
cascade of "field is undefined" bugs further down the stack
- Forces explicit version bumps when we make non-additive schema
changes — the bump rules are documented inline next to the constant
- Cheap to remove if it ever feels overkill: drop the envelope() call
on the backend and the unwrapEnvelope on the frontend, ~10 lines
═══ 2. Anthropic prompt-caching directive (forward-compat) ═══
Adds `providerOptions: { anthropic: { cacheControl: { type: 'ephemeral' } } }`
on the system message in nutriphi + planta routes via a SYSTEM_CACHE_HINT
constant. This is a NO-OP today because:
- mana-llm currently routes to Gemini, not Claude
- Our system prompts are ~50 tokens, well under Anthropic's 1024-token
cache minimum
Kept anyway because it's ~5 lines per route and lights up automatically
when either condition flips (e.g. when we add per-user dietary preferences
as system context, pushing prompts past the threshold). The day we point
mana-llm at Claude Sonnet, every existing call site already has caching
enabled — no scavenger hunt through the routes.
System messages had to migrate from the `system:` shorthand to a full
messages[] entry to attach providerOptions, which is a tiny readability
loss but the only way to get per-message metadata into the AI SDK.
═══ Tests ═══
13 new cases in apps/mana/apps/web/.../nutriphi/ai-schemas.test.ts cover:
- AI_SCHEMA_VERSION presence + AiSchemaVersionMismatchError shape
- MealAnalysisSchema acceptance/rejection (confidence bounds, missing
nutrients, optional food fields, default empty arrays)
- PlantIdentificationSchema (every-field-optional design, defaults,
confidence range)
(Test file lives in the web app rather than packages/shared-types
because the latter has no test runner configured — adding vitest there
just for these would be overkill.)
Total nutriphi + planta suite: 62/62 passing.
