`add_diameter_dim` / `add_radius_dim` measure to the point they are handed; `leader_length` is a text placement. The ezdxf backend passed `centre + (radius + leader)` as that point, so the leader became part of the measurement: a true 40 mm bore was dimensioned 60 at the default `leader_length=10`, and 108 at 34. Radius callouts were `leader_length` too large the same way. This is the worst class of defect for this project -- a wrong number, at default settings, on the one part of a drawing that exists to carry numbers -- and it shipped in v1.4.0 and earlier. The size now comes from `radius` and `location` only places the text. The live COM backend was never affected: ActiveX's AddDimDiametric takes the two chord points and the leader length as separate arguments. The two engines had been disagreeing by 2 x leader_length on the same call. Found while building the drawing for the new README, whose own bore callout was wrong. Two checks added to correctness_suite.py; both report fail -> pass against v1.4.0, not miss -> pass, which is what separates a repaired defect from new capability in that lane. A/B is now 21/26 -> 26/26, five fixed, zero regressed. README rewritten from scratch - Hero is a real ISO A3 sheet the server drew: m6 z24 involute spur gear, DIN 6885 keyed bore, section A-A, ISO 129 dimensions, ISO 286 H7 fit, ISO 7200 title block, 56 entities, drawing_critique clean. New scripts/render_readme_showcase.py rebuilds it, and the tool-call sequence that produces it is printed in the page. - Star history chart, badge row, capability matrix, five evidence lanes, and a "what this release is bad at" section carrying the 28% throughput regression. - Every image and repo link is now an absolute URL: README.md is the PyPI long description, where relative paths 404. Corrections this work forced, all measured - The df=0 example was wrong. FILLET is already in entity_fillet's own text; the commands that genuinely scored zero are WBLOCK, PEDIT, OVERKILL, LAYTRANS and MATCHPROP. - 40,305 tokens is the tools/list wire payload; ~25,143 is the part forwarded to the model. The old wording said "of schema", which is neither. - `--tokenizer anthropic` needs a package and credentials this repo does not lock, and refuses rather than falling back. Said so. - Discovery ranks over the 149-tool advertised catalog, not the 154 registered. - Five middlewares, not four; the fifth is what makes refusals machine-readable. - Five of the 27 capability keys are environment-dependent, so the matrix carries footnotes instead of bare ticks. - "Every coordinate is WCS" has one deliberate exception: TEXT rotation. - render_live_chart's axis still said "fixed 10-task matrix" while our bar came from v3's fifteen. Each bar now carries its own matrix. - .env.example said MAX_UNDO_STACK=50 (code: 5) and omitted four real variables, two of them the remote-HTTP controls. - server.json described an empty ALLOWED_PATHS as blocking access. It disables the allowlist. - server.py called the lean profile ~46 tools; it is 47. - backends/capability.py cited a test file that does not exist. 1249 passed, 1 xfailed.
