Research snapshot of the AutoCAD MCP field (20 READMEs, 2026-09-14), the
seven 1.6 tracks with measurable acceptance criteria, their order
(A -> E -> B -> G -> F -> H -> D), and the tool-pack decision.
Track A: symbol catalogue authored in code (ISO 10628-2 + ISA-5.1), two
generic contracts (block_define, entity_get/set_xdata), nine pid_* tools,
routing, the ISA-5.1 tag grammar, the pid_graph reader, six critique
focuses, TOOL_PACKS, and the test/evidence plan.
