tigrbl_engine_xlsx is an XLSX engine plugin for Excel workbook-backed table access where each worksheet is exposed as a Tigrbl table.

tigrbl_engine_xlsx 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

• Excel workbook-backed tables, worksheet-to-table mapping, workbook persistence, and spreadsheet data 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.
