tigrbl_engine_memqueue is an in-memory queue engine plugin for process-local queue semantics for Tigrbl task and message workflows.

tigrbl_engine_memqueue 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, OpenAPI/OpenRPC documentation surfaces, and PyPI distributions that complete the system.

Engine ownership and database guards

• process-local queue semantics, task/message ordering, and queue lifecycle 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.

Package ecosystem cross-links

Every Tigrbl Python package links to its sibling distributions on PyPI so package indexes, search engines, answer engines, dependency scanners, and human readers can move through the installable package graph without falling back to source-tree paths.
