Overview

Base for the RBS-derived cache producers.

Every producer (‘RbsKnownClassNames`, `RbsConstantTable`, `RbsEnvironment`, the ancestor / type-param / definition tables, …) repeated the identical `fetch` wiring: build the RBS descriptor, then `store.fetch_or_compute` under the producer’s id, yielding to the producer’s ‘compute`. Only the `PRODUCER_ID` constant and the `compute(loader)` body actually differ between producers.

Subclasses declare ‘PRODUCER_ID` and a (private) `self.compute`; this base owns `fetch`. `self::PRODUCER_ID` resolves the constant on the concrete subclass, and `compute(loader)` dispatches to its private class method. See the `_CacheProducer` RBS interface for the structural contract.
