// This example is embedded IN the metaobjects monorepo (not `npm install`ed),
// so there is no scaffolded ADR-0034 owned-copy target for it to import from
// (`meta init`'s codegen/generators/*.ts copies resolve their OWN imports via
// a real package install, which this repo-local example doesn't have). A real
// consumer project runs `meta init` and gets local, editable owned copies —
// see CLAUDE.md "Codegen architecture (Vite-style plugins)". Here every
// generator is imported directly from the package.

// `entityFile`/`queriesFile`/`routesFile` derive DB participation from a
// declared/inherited `source.*` child (the #248 persistability contract), so
// the sourceless shapes here need no filter for them: `entityFile` renders a
// sourceless shape as SHAPE-ONLY output (interface + Zod, no Drizzle table —
// see ProgramDescriptionPayload.ts in src/generated/), while `queriesFile`/
// `routesFile` skip it outright. The sourceless shapes: the pure
// `object.value`s (SyllabusSection / InstructorProfile — a value can never
// declare a source, loader-enforced) and the SOURCELESS `object.projection`
// payload (ProgramDescriptionPayload, #210 — assembly origins live on
// projections; a template payloadRef may target a sourceless projection).
// `formFile` is the one generator that does NOT yet make that distinction —
// it assumes every passing entity is form-submittable — so it alone needs the
// config-level `filter` (the option exists for exactly this): only a PERSISTED
// object is form-submitted in this domain.
