description	Audit and fix persistence wiring so the repository adapter (TypeORM/Firestore/other) stays swappable. Use when adding or reviewing entity/repository code, when you see @InjectRepository or a module-local TypeOrmModule.forFeature, or when checking that core/feature packages don't hard-require an ORM. Triggers on "is this persistence swappable", "register this entity", "review repository usage".

Persistence-Agnostic Linter

The supported contract is RepositoryInterface + dynamic repository keys. Concrete backends are selected in module options and must stay swappable. Flag and fix anything that nails the code to one ORM.

Reject these

• @InjectRepository(...) / importing Repository from typeorm in core or feature code.
• A module-local TypeOrmModule.forFeature([...]) to register a feature entity.
• ORM types (FindManyOptions, DeepPartial, SaveOptions, TypeORM EntityManager) in rockets-core public surface, types, or docs.
• The same entity/key registered in two places, or key and class split across files.

Require instead

• @InjectDynamicRepository(KEY) + RepositoryInterface<Entity>. Feature/server code imports these from @concepta/rockets-core (it re-exports InjectDynamicRepository, RepositoryInterface, RepositoryModuleInterface, Where, getDynamicRepositoryToken). Only core/lower packages import from @concepta/rockets-repository directly.
• Entity registration through bundles in resources[]: defineResource() auto-contributes its entity row; defineModuleResource({ entities: [...] }) contributes extra rows; userMetadata.entity for the metadata row.
• A single top-level repository: RepositoryModuleInterface (default adapter) at the module root; per-entity repository override only when one table needs a different backend. No repositories.entities[] block.
• For the zod layer: entity generation goes through a SchemaEntityCompiler adapter (e.g. typeOrmZodEntityCompiler), never TypeORM imported directly into rockets-zod.

How to audit

1. grep -rn "@InjectRepository\|from 'typeorm'\|TypeOrmModule.forFeature" packages/*/src — every hit in core or a feature is a finding (example/sample apps may legitimately pick TypeORM as the concrete adapter).
2. Confirm each entity is registered exactly once, via a bundle, not a module-local forFeature.
3. Confirm rockets-core builds and type-checks with no ORM symbol in its public index.ts.

When you fix a violation, migrate it to the dynamic-repository pattern — do not cast around the type. If a real gap blocks the abstraction, stop and ask rather than leaking the ORM.
