BusinessCentral.AL.Runner

Pipeline architecture, stage-by-stage flow, BC→mock type rewriting, and the key-file map for AlRunner. Use when modifying AlRunner/ source (Program.cs, RoslynRewriter.cs, Pipeline.cs, Runtime/**), debugging compilation/transpilation issues, adding new mock types, understanding why a BC type is or is not rewritten, or interpreting non-zero exit codes (1/2/3).

How to write, place, and run AL test suites in this repo — proving-test rules, bucket/category layout, AL object-ID uniqueness, run-all-buckets command, build commands, stubs invocation. Use when adding a test suite under tests/, picking object IDs for a new codeunit/table/page, running the test matrix locally, or evaluating whether an existing test "proves" anything.

Multi-agent workflow contract for this repo — orchestrator vs implementation agents, GitHub label state machine (status, agent), PR lifecycle, and the role of `al-runner --guide`. Use when acting as orchestrator/impl-agent without the dedicated sub-agent, when triaging the issue/PR queue manually, or when updating runner capabilities (must update PrintGuide() in lockstep).
