CLAUDE.md gains items 18-20 (styles, page setup & templates, environment),
the grown drawing_settings facade on item 11, lean 55 / 52 and
TOOL_PACKS=all|core,pid,settings, and three conventions: layer states are
ours (ACADMCP_LAYERSTATES XRECORD, mode "xrecord"), page-setup evidence is
the PDF's own /MediaBox, nothing interprets coordinates in UCS.
README token table re-measured on this tree with benchmarks/token_suite.py
(ratio/v1 estimates): full 199 tools / 59,315 tokens, core,settings 190 /
55,593, core 168 / 48,825, lean 55 / 16,360, search 2 / 356; corpus
re-derived from discovery.aliases: 186 AutoCAD command names, 933 synonym
phrases, 204 tools. Styles & standards row, page setup & templates row,
final environment wording, and "Known limitations of the settings track".
CHANGELOG Unreleased: the track E intro, Added (styles, page setup &
templates, environment, drawing_settings growth, benchmark evidence),
Fixed (the Track A hardening list), Changed (three groups, packs, measured
idle cost, release snapshot 204 · 8 · 5 · 3284). Spec status: implemented.
Where the plan's text and the tree disagreed, the tree wins:
mleaderstyle_create is implemented on both engines through the
ACAD_MLEADERSTYLE dictionary and no `mleaderstyle` capability key exists
(spec §4, capability maps), so the docs say so instead of calling it
ezdxf-only; the Task 7 fix (tolerant ACADMCP_PID payloads, crossings
tested against the arc) joins the hardening list the plan left it out of.
