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.

Two authoring slips in the valve x actuator composition:
- The diaphragm actuator's stem stopped at y=4 while the dome's flat base
sat at y=6, so the canonical control-valve symbol (PID_VALVE_*_DIAPHRAGM,
9 catalogue entries) shipped with its dome floating 2 mm above the stem.
- Actuators were placed at a fixed y=4 regardless of the body, so on the
needle body (top 5.6) the piston/motor/solenoid glyphs were drawn over
the knob and the hand bar across the needle's stem; the stem line(0,0,0,4)
also duplicated the needle's own axial line (and the butterfly disc).
Placement is now body-relative: `_body` reports `axis_top` (where its own
geometry on x=0 ends) and the stem runs from there to the glyph base at
`body_top + STEM_CLEARANCE`; the diaphragm dome's base is the stem top
(base + DIAPHRAGM_YOKE), and the FAIL attribute follows the glyph base.
The reference 8x4 bodies keep their published numbers (globe+diaphragm
signal at y=9.0, bbox top 9.0).
Tests: per-combination check that the stem starts at the body's derived
axis top, the glyph's lowest edge equals the stem top, the glyph clears
the body, and the signal port is the topmost edge; plus a catalogue-wide
no-duplicate-primitives gate. 33 combinations fail on the old geometry.
The plan's Step 3 snippet is synced with the fixed module.

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.
