 The Client runs in one of two modes selected at construction:
 
 - **Single-tenant** (default). The constructor receives a non-nil `*sql.DB` / `*mongo.Client`. Reads serve from an in-process cache; writes upsert through the store and update the cache. The backend's changefeed (LISTEN/NOTIFY on Postgres, change stream on MongoDB) drives invalidation and fires `OnChange` subscribers.
-- **Multi-tenant** (opt-in via `WithMultiTenantEnabled()`). DB/client may be nil. Every read/write resolves the tenant database from `ctx` via `tmcore.GetPGContext(ctx, module)` / `tmcore.GetMBContext(ctx, module)` (`lib-commons/v5/commons/tenant-manager/core`). For Postgres the lib performs NO runtime schema provisioning — `systemplane_entries` plus its NOTIFY trigger function/triggers must be created externally via `SchemaSQL()` / `DefaultSeedSQL()` (e.g. the consumer's migration pipeline); the runtime role only needs DML + `LISTEN`. (MongoDB still bootstraps its collection/indexes lazily once per resolved tenant database via a `sync.Map`-backed `sync.Once` cache.) No in-process cache. No LISTEN/NOTIFY. `OnChange` returns `ErrNotSupportedInMultiTenant`. Callers wire `tenant-manager/middleware.TenantMiddleware` (with `WithPG(...)` or `WithMB(...)` and a matching module name) before the lib's handlers.

 - Sentinel errors: `ErrClosed`, `ErrNotStarted`, `ErrRegisterAfterStart`, `ErrUnknownKey`, `ErrValidation`, `ErrDuplicateKey`, `ErrNilContext`, `ErrNotSupportedInMultiTenant`, `ErrTenantConnectionMissing`.
 - `NewForTesting(s TestStore, opts ...Option) (*Client, error)` is an explicit out-of-package test helper. Build-tag gated (`unit`/`integration`); not a promised production API.

 > **Provisioning (Postgres).** The library no longer creates its schema or seeds defaults at runtime. Provision `systemplane_entries` (plus the `systemplane_notify_v3()` trigger function and the NOTIFY triggers) and any defaults externally — e.g. via your migration pipeline — using the DDL published by [`SchemaSQL()` / `DefaultSeedSQL()`](#schema-provisioning). The runtime database role only needs DML (`SELECT`/`INSERT`/`UPDATE`/`DELETE`) + `LISTEN`; it does NOT need `CREATE` on the schema.
