A continuation of "The acraflow middleware worker apparatus" with a deep inventory of token-conservation features — the implemented mechanisms that realize the middleware's design. This enhanced gist catalogs the full repertoire of levers, handlers, components, and directives that make token-efficient solving possible: from cached grounding to deterministic routing to synthetic pre-staging, every feature that saves tokens (or ensures they're spent wisely).
Once a problem is solved, re-encountering it should cost no model call.
