2 * TASK-0124 — Database AI: prompts, tool specs + server-side validators.
3 *
4 * The three database-generation features (generate / extract / formula) all
5 * follow the TASK-0123 writing pattern: the client sends IDs + untrusted text
6 * only; this module is the single choke point that assembles the prompt,
7 * declares the structured tool, and VALIDATES the model's tool call before any
8 * write (spec §Security, AGENTS #19). Invalid structure → retry once with the
9 * error as feedback → then a 422 (`ai_invalid_structure` / `formula_invalid`)
10 * with NO partial write.
11 *
12 * The shared zod schemas + allowlist + markdown parser + deterministic mock
13 * live in `@factory/ai` (`packages/ai/src/schemas/database.ts`) — one source
14 * of truth for the LLM tool schema, the server validator, and the mock.
15 *
16 * NOTE (recorded, spec-vs-reality §29): the spec says "22 PropertyType values"
17 * and names an `extraction` type. The real `enum PropertyType` has 24 values
18 * and no `EXTRACTION` member. We mirror the real enum (the architecture is the
19 * source of truth) and express the generated-property allowlist as
20 * `GENERATABLE_PROPERTY_TYPES` (19 of the 24 — the rest are reserved / need a
21 * target / are engine-computed). See the schema's `NON_GENERATABLE_PROPERTY_TYPES`.
