tigrbl_engine_memlru is an in-memory LRU engine plugin for process-local least-recently-used cache behavior for Tigrbl workflows.

tigrbl_engine_memlru is part of the Tigrbl package graph. It documents package-resident classes, concepts, extension points, and execution responsibilities while cross-linking to the facade, core specs, canonical mapping, runtime phases, concrete objects, operation packages, engine plugins, and Rust crates that complete the system.

Engine ownership and database guards

• process-local least-recently-used eviction, memory cache sizing, and eviction guardrails.
• Engine packages document backend-specific connection settings, session construction, transaction behavior, persistence boundaries, and operational guardrails. Transport routing and operation semantics remain in the facade/canon/runtime/ops packages.
• Register this engine through the package entry point or the Tigrbl engine context so API code can select the backend without embedding backend-specific logic in model definitions.
