38 tools in three sections: ISO-25/ANSI dimension, text and leader styles
with drawing_apply_standard; drawing_settings growth, a system-variable
catalogue and document properties; page setup with PDF mediabox read-back,
batch plot and five bundled templates built by the server's own tools;
multi-document on both engines, portable layer states, named views, UCS,
launch, preferences and operator prompts. Track A hardening is wave 0.

scripts/smoke_pid_com.py runs the whole track against the live AutoCAD in
a new document. ComBackend.connect() is lazy by design, so the script reads
reachability from system_status()["connected"] rather than from connect()
as the plan sketched, and closes its document without saving unless --keep
is passed. On this machine (AutoCAD 2026, "25.1s (LMS Tech)") it exits 0:
5 nodes, 4 edges, 0 dangling, confidence_min 1.0, 0 critique issues,
2 XDATA chunks — identical to the headless engine on the same spec. The
first attempt exited 2 on a stale win32com gen_py cache (a package folder
holding only __pycache__); an environment fault, no backend change needed.
A/B against v1.5.1 published as ab-v1.5.1-vs-v1.6.0-dev.json: 26/29 ->
29/29, three miss -> pass, zero regressed. check_doc_numbers.py now names
the report and the two row labels in one place (AB_REPORT, AB_*_LABEL),
and README.md / benchmarks/README.md carry the new rows; the v1.5.0 and
v1.4.0 tables stay as history.
README: P&ID row, the showcase and catalogue images, the token table
re-measured (161 / 44,930 by default, 152 / 41,420 with TOOL_PACKS=core,
lean 50 / 14,007), every stale count reconciled (154 -> 166 registered,
149 -> 161 advertised, corpus 158/672 -> 162/731 by the same count, 19 ->
20 groups, 6 -> 8 resources, six-task matrix with pid_roundtrip), a
"Known limitations of the P&ID track" subsection, and the snapshot line at
this machine's 2423 collected tests (CI has not run on this tree; noted in
the changelog with the pre-existing 1369 vs 1363 drift).
CLAUDE.md: section 17, sections 5 and 7 counts, TOOL_PACKS, the two 1.6
contracts and the reader rules. Spec status -> implemented. The plan and
spec markdown were reformatted by ruff (fenced Python only) because
`ruff format --check .` was already red on them at HEAD and the gate
requires the whole tree clean.

Plan covers the prerequisite block_insert attribute fix (ezdxf wrapped the
INSERT in an anonymous *U block and lost its ATTRIBs), the two generic
contracts, the 43-symbol catalogue, routing, the ISA-5.1 grammar, the
graph reader, deliverables, six critique focuses, pid_from_spec, TOOL_PACKS,
resources, benchmark v4, and the live COM smoke.
Spec reconciled with the plan: 43 base symbols, FUNC/LOOP at +-2.0,
solid = DXF SOLID entity, shape/direction options, example spec uses an
actuated FCV-101 (a hand valve has no signal port), refine hints in
detail["hint"], preflight LAYER_SET_INTENT_MISMATCH, radial port matching
on the circle.

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.
