Umut CANandClaude Opus 5.5 e640def4ff feat(understand): orthogonal lengths and pipe takeoff rows
route.py: Manhattan distance, the rectilinear minimum spanning tree (Prim
over |dx| + |dy|, exact on the points given) and the x-then-y route.

pipe_rows turns the P&ID's runs into rows by room x service x diameter.
length_source auto measures on the P&ID only when the scale check calls it
to scale; otherwise each run is the RMST of its tags' layout positions plus
vertical_allowance per connection, with the drawn length kept beside it as
schematic_m. length_source=pid on a schematic P&ID is refused with the
statistics unless force=True. Status A / B / C; a C run goes to control
with its schematic length, counted and flagged. Routed lengths are shared
among the layout rooms their route crosses (track F's face finder); the
allowance is its own column. Lengths are metres from the unit the geometry
implies: a layout declaring inches over millimetres is read in mm and warned
about, never multiplied by 25.4.

The takeoff carries narrow stand-ins for the unit inference, the plan-copy
clusters and the scale check (group U's modules are on another branch); a
scale result passed in is used first. Tags written twice in the chosen
cluster are ambiguous, never picked.

Beyond the plan: the scale stand-in calls a non-positive median ratio
insufficient (as group U's scale_check does) instead of to_scale with a
factor of 0; an INSUNITS code the reader does not convert is named in the
unit warning instead of being called "no unit"; wall layers are classified
once per layer, not once per record.

Umut CANandClaude Opus 5.5 7bfba02ef0 fix(task-5): fittings bridge every port pair, reducers found however the pipe meets them, unread-layer lines keep their labels
- A three- or four-way fitting joined its ports as a star around the port
  seen first, so the diameter carried into an unlabelled branch depended on
  record order. Every port pair is now bridged; two sizes equally near stay
  unassigned whatever the order (six-order parametrised test).
- A reducer was seen only through free ends in its box. It is now also found
  where pieces meet at a vertex inside its box (a line broken at the
  reducer) and where a straight segment is drawn through the middle of its
  box (cut at the foot of the box centre). A direct label holds for its
  entity only on its side of every reducer.
- A diameter or direction label nearer to an open line on a layer that is
  not read belongs to that line: it is dropped and listed in
  stats.labels_skipped instead of landing on the nearest read pipe.

Headless engine only: no new ActiveX call, so no live probe applies.

Umut CANandClaude Opus 5.5 1426c53fd3 feat(understand): the line-network engine - runs, services, diameters, equipment
build_network reads the segments of a foreign P&ID's piping and electrical
layers into runs: ends merged within tol, a branch ending on a header split
into a tee, a crossing without an end left unconnected, and a line drawn
twice - or a line over a polyline - cut into identical pieces that are kept
once, the doubled length reported as overlap_length. An INSERT holding two to
four free ends is an inline fitting joined through; a reducer word in its
block name (reducer, perekhod, reduksiyon, verloop, reduzier) stops diameter
continuity.

Each diameter label goes to the nearest piece and holds for its drawn entity
(direct); unlabelled pieces take the nearest direct diameter along the run
(continuity) or stay unassigned - two sizes equally near are never guessed.
Labels stay as drawn. A supply or return word near a run overrides its
layer's service for the whole run. Run ends attach to the tag whose labelled
geometry holds them; a shape holding two tags (a room, a skid) is not
equipment. Tests on hand-built drawings and on the synthetic plant pair.

Beyond the plan: a CIP / glycol layer naming no direction (classify_layer
files it `unknown` on purpose) now takes its direction from the word instead
of staying unknown; is_reducer matches on vocab.fold and knows the German
word equipment_kind already had; the fitting, equipment and attachment
lookups go through grid indexes - measured 149 s -> 2.8 s on a 59,200-record
synthetic drawing, results identical to the plan engine on it and on the
plant pair. No ActiveX call is added (pure module).

Umut CANandClaude Opus 5.5 704a44b190 test(understand): the synthetic plant pair - a schematic P&ID and its layout with known answers
Every track H reader is measured on this pair, never on a client drawing
(spec section 14). tests/fixtures/plant_pair.py writes pid.dxf and layout.dxf
with invented names and returns their truth, computed from the positions it
placed:

- the P&ID is room 1 of the layout stretched 1.3x and room 2 rearranged, so
  21.8 % of the 55 tag pairs fall within 10 % of the median ratio (schematic)
  while room 1 alone is 100 % at 1.3;
- service layers in English and Dutch, Russian supply / return words, one CIP
  return drawn on the supply layer, sizes spelled as drafters do (an MTEXT
  format run, %%c, \U+2205, the U+2300 sign, o-stroke, SMS, DN, 20x27), a
  reducer, inline valves, an arc bend, a segment drawn twice;
- electrical texts in Russian with the power stated for all loads but one;
- a layout declaring inches over millimetre geometry, a stray line 5,000 km
  out, two plan copies 100 m apart, wall outlines, room labels and wiring
  callouts in four spellings.

Run lengths are the rectilinear MST of each run's tags, cable metres are
the Manhattan length rounded up after the 20 % allowance; the generator
refuses to write a pair whose own premises fail.

Umut CANandClaude Opus 5.5 9ab0ae1773 feat(understand): the snapshot, the vocabulary and the label parsers; MAX_DXF_BYTES 512 MB; the office extra
Track H's foundation, landed on main before its three groups branch.

- engineering/understand/snapshot.py: one bulk read of a drawing into frozen
  WCS records (OCS translated through backends/ocs.py, text decoded, an
  INSERT boxed by its block geometry without its attribute texts). A DXF is
  read with ezdxf after the size check; the headless engine's document is
  read under its own lock; the live engine exports the active document with
  Document.Export(<tmp>/snap, "DXF", <set of all>) - never renamed, deleted
  afterwards - and a DWG is opened read-only, exported and closed. Measured on
  AutoCAD 2026: ".dxf" is refused with Invalid argument, the file lands as
  snap.DXF, model space, paper space and unused block definitions all reach
  it, and the selection set does not narrow a DXF export.
- engineering/understand/labels.py: %%c, \U+2205, the U+2300 sign, o-stroke
  and MTEXT format runs all read as one diameter spelling; sizes are kept as
  drawn and never equated; Cyrillic look-alike capitals fold into Latin tags;
  panels, wiring callouts and electrical data (kW, phases, volts, N, VFD) in
  EN / TR / RU / NL / DE. A power that is not written stays None.
- engineering/understand/vocab.py: layer classification with a confidence and
  the deciding keyword, supply / return words, room labels and block kinds in
  five languages. A CIP layer without a direction word is not guessed.
- MAX_DXF_BYTES defaults to 512 MB (a real layout was 188 MB); the refusal
  names the size and the variable. New `office` extra (openpyxl), also in
  `full`; uv.lock regenerated.

Umut CANandClaude Opus 5.5 f0c50d772f docs(spec,plan): track H states what it does with xrefs
The spec promised that the first live task would measure xrefs. It never
did: the plan measures model space, paper space and block definitions. 1.6
does not read an xref's own entities on either engine; the host drawing is
what gets read. The snapshot docstring and drawing_understand's docstring
now say so, and nothing is claimed about the live engine that was never
measured.

Umut CANandClaude Opus 5.5 9b45243bdd docs(plan): track H task 11 reads units, plan copies, scale and rooms once
The reconcile pass left one real defect for the reviewer. Groups U and N are
built side by side, so the takeoffs carry their own unit bands, cluster grid,
scale statistic and room faces, and nothing ever retires them. Two readers of
one drawing can disagree. On Task 6's own inches-over-millimetres layout,
infer_units without room faces ties three ways and falls back to the header,
while the takeoff's bands say mm.

Task 11 gains Steps 15-20, committed on their own before the README figures
are retaken:
- describe.drawing_units becomes the one unit call, used by describe,
  scale_check and the takeoffs;
- the takeoffs read plan copies, scale and rooms through group U's modules;
- the stand-ins are deleted;
- tests/test_understand_one_reading.py pins one unit, one plan copy, one
  verdict and one set of rooms per drawing.

Tasks 3, 4 and 6 now point at those steps. Review Focus 1 names
parse_diameters, the function every task uses.

Umut CANandClaude Opus 5.5 7f82766d38 docs(plan,spec): track H examples carry invented values only
A second pass compared every tag, number and literal in the plan with the
field files, locally. Two borrowed values remained: a motor rating and one
motor tag. Both are now invented (18,5 kW, M82), and the dependent sums and
section rules were checked against them. The rest of the tank series was
renumbered to keep its old sort order, since several assertions compare
sorted tags: T4101-T4103, T4500 and T4600.

Docstrings no longer tie example layer names to a particular drawing. The
fixture's claim now says exactly what is invented (every tag and number) and
what is ordinary drafting vocabulary (layer and block names). The spec's
grounding paragraph now says "process plant" and no longer names the sector.

Umut CANandClaude Opus 5.5 77db39804a docs(plan): track H examples use synthetic equipment tags
The skeleton's examples (and the tests drafted from them) borrowed equipment
tag numbers seen in the field drawings. They identify nothing on their own,
but the plan's own rule is that every example and fixture is synthetic, so
they are replaced by invented tags of the same shape and sort order
(T41xx-T44xx, M41A, M47.1, M82, CP-M82), Cyrillic spellings included.

Umut CANandClaude Opus 5.5 023eac7a51 docs(plan): track H — 12 TDD tasks in three groups
The skeleton's header, constraints, file map and pinned interfaces now carry
their twelve tasks, in order:

- main (Tasks 1-2): the snapshot, vocabulary and label parsers, MAX_DXF_BYTES
  512 MB and the office extra; the synthetic plant pair with its truth.
- U (Tasks 3-4): drawing_understand and drawing_scale_check; SECTION 26 opens.
- N (Tasks 5-8): the line network, orthogonal lengths and pipe rows, the
  takeoff workbook with pipe_takeoff, then cable_takeoff; SECTION 27, pack plant.
- D (Tasks 9-10): drawing_diff and drawing_topology_check with the three
  topo_* focuses, on D's own copy of SECTION 26.
- final (Tasks 11-12): packs, lean 65, aliases, golden queries and counts;
  benchmark v7, five correctness checks, the live smoke, the field-test
  script and the docs.

Interface pass: the U and N texts now say what Task 6 really does with the
scale check (it takes one through pipe_rows(scale=...) and otherwise keeps its
own stand-ins), and Task 11 moves D's block above SECTION 27 after the merge.

Umut CANandClaude Opus 5.5 18995bf854 docs: track H (understanding foreign drawings) design spec
Read a drawing somebody else made and turn it into a deliverable: a one-call
drawing report (units that lie, stray extents, plan copies, multilingual layer
meaning), a scale check between a P&ID and its layout, pipe and cable takeoffs
whose topology comes from the P&ID and whose lengths come from the layout, a
revision diff by geometric signature, and topology checks. Grounded in a real
client project read locally (never committed): its P&ID proved to be
unscaled against its layout, which no tool had flagged.

Six tools (+ pack plant), three topo_* focuses, the office extra, a live DXF
snapshot through Document.Export (measured: the document is not renamed), and
synthetic fixtures that reproduce the field findings.

Umut CANandClaude Opus 5.5 0abbe55041 bench: matrix v6 adds arch_roundtrip; four architectural correctness checks; the live arch smoke
The evidence for track F, in the shape tracks A, E and B + G used.

- benchmarks/tasks_v6.py: 19 tasks, DEFAULT_MATRIX = "v6"; v5 to v2 stay
  addressable. arch_roundtrip draws the example plan with
  arch_plan_from_spec and reads it back without the spec: rooms_detect must
  find each labelled room within 0.1 % of its label and of the net floor
  computed by hand (4825 x 5750 and 3825 x 5750), the schedules must list
  D1, D2, W1, W2, and the plan is gated on a zero-issue critique and a
  finalize score of at least 90. A test removes one room label and the gate
  fails naming arch_room_unlabelled.
- Four correctness checks, every number worked out by hand in the docstring:
  L / T / X junction corners and wall areas, a 4 x 5 m room labelled 20.00 m2
  rather than its 21.84 m2 axis area, a door interrupting both faces, and a
  plan of plain lines read as 20 and 15 m2 at confidence 0.6. The published
  A/B report is re-run over 43 checks: 26 / 43 -> 43 / 43, zero regressed.
- scripts/smoke_arch_com.py runs the whole plan once on a live seat and
  closes every document it opens; the CHANGELOG records what it returned.
- The token suite measures a TOOL_PACKS=core,arch row; check_doc_numbers
  derives the task count from the v6 matrix; CLAUDE.md, both READMEs and
  the spec status line say what shipped.
- fix(com): the first live smoke exited 1 - the room reader found 0 wall
  segments. Measured on AutoCAD 2026 (2026-09-23): with a makepy cache,
  ModelSpace.Item(i) returns the gen_py IAcadEntity wrapper
  (type(item).__name__ == "IAcadEntity") and item.StartPoint on an
  AcDbLine raises AttributeError, so every entity_list row lost its
  type-specific properties (28 wall LINEs, 0 with start/end). _entity_info
  now re-dispatches exactly that wrapper through _com_unnarrow; after the
  fix 38 of 53 rows carry start/end and the smoke exits 0 with both rooms
  at 27 743 750 / 21 993 750 mm2 and 0 critique issues. Re-dispatch
  measured at ~1.7 ms per entity (dynamic vs gencache alike).

Umut CANandClaude Opus 5.5 6e004cc658 feat(arch): arch_plan_from_spec, three arch_* critique focuses, the arch pack, lean 64 and the counts
The three track-F branches are merged; this is the integration that makes the
twelve SECTION 25 tools one surface.

- engineering/arch/spec.py: a whole plan from one document - walls with their
  openings, stairs, room labels measured off the walls just drawn, the
  exterior chains and the schedules - inside one transaction. Everything the
  model, the wall engine or the stair symbol can refuse is refused before the
  transaction opens, by path; a room point in no closed face rolls it back,
  and so does a cancelled request, under the anyio shield of pid/spec.py.
  EXAMPLE_SPEC's rooms measure 4825 x 5750 and 3825 x 5750 - the net floor,
  computed by hand in the tests.
- engineering/arch/critique.py: arch_room_unlabelled, arch_wall_gap (50 mm,
  one issue per pair of walls, measured to the wall body so an L corner and a
  T stem both read as joined) and arch_opening_clash. One index per critique
  run; a drawing without an ACADMCP_ARCH record yields nothing. Each focus
  has a positive and a negative fixture.
- TOOL_PACK_NAMES gains "arch" (the twelve SECTION 25 tools); lean gains
  arch_wall, arch_opening, arch_room and arch_plan_from_spec and reaches 64;
  the arch tag ranks after mech, so SECTION 25 files as one `architecture`
  group - 241 tools in 26 groups.
- Six golden tuning cases, two of them Turkish, the arch_plan_from_spec alias
  record, the shared-command allowlist reconciled with what the merged records
  claim, the inventory regenerated, the registry snapshot retaken, and the
  README figures taken from check_doc_numbers rather than typed.
- Two more Turkish golden cases close the reconciliation's alias gaps
  ("vaziyet planı çiz" -> arch_plan_from_spec, "oda alanlarını hesapla" ->
  arch_rooms_detect); the arch records carry vaziyet / alan / oda / kat planı
  in diacritic and ASCII-folded spellings, because the search tokenizer splits
  on a non-ASCII letter. BOUNDARY and AREA stay with boundary_trace and
  analysis_measure_entity on purpose, recorded in the arch alias comment.
  Tuning top-1 73/84, top-3 83/84; holdout top-3 15/15.
- tests/test_token_suite.py: TOOL_PACKS=core,mech now drops the arch pack
  too (measured 193 = 236 - 9 - 22 - 12).

Umut CANandClaude Opus 5.5 cd1ae3529c feat(arch): SECTION 25 opens - walls, openings, stairs and exterior chains as tools
engineering/arch/draw.py is the only module of the track that touches a
backend. It draws through draw_prims(role_layer=ARCH_ROLE_LAYER) and the
generic contract members, so it runs on both engines as written, and it writes
the plan onto the drawing: each element's ACADMCP_ARCH record on one of its own
entities (a wall's first face line, a door's leaf, a window's frame, a stair's
first riser) and, beside it under ACADMCP_ARCH_H, the handles that element
owns. read_plan reads the records back and never modifies the drawing.

arch_wall computes the whole network before and after the new walls and
redraws only the drawn walls whose outline changes - erasing exactly the
entities they own - and says which under redrawn. arch_opening hosts a door or
a window in a drawn wall found by id and redraws that wall cut; its tag
defaults to the next D1/W1 (K1/P1 in Turkish). A new wall that would leave a
drawn opening uncuttable, and an opening that runs into a junction, are refused
before anything is erased. arch_stair reports the Blondel value; it does not
enforce it.

exterior_chains gives each side up to three rows, nearest first: every jamb in
that facade, both faces of every wall meeting it, and the overall - from the
wall engine's own faces. A row that would only restate a farther one is not
emitted (ISO 129-1: each measurement once). The 10 mm / 8 mm row spacing is a
declared drafting default times the plot scale, not a standard value.

The arch tag is ranked after mech so the four tools file under a new
architecture group; alias records carry WALLADD/MLINE, DOORADD/WINDOWADD and
STAIRADD with English and Turkish shop words. Inventory regenerated; README
snapshot 233 tools (228 advertised) in 26 groups; registry snapshot
architecture: 4.

No new ActiveX member is called. Measured on AutoCAD 2026 in a scratch
document through ComBackend: shell + teed partition, D1 + W1, a straight 17-riser stair
and the bottom chains gave the same 20 wall LINEs (identical endpoints),
9 poche HATCHes, 1+1 door, 4 window lines, 11 dimensions and a read_plan
round trip as the headless engine.

Umut CANandClaude Opus 5.5 9168d61397 feat(task-6): door, window and room schedules read from the drawing
engineering/arch/schedule.py turns the plan records into schedule rows: doors
by tag with width, height, swing, hand and wall; windows by tag with width,
height, sill and wall; rooms by number with name and the measured area the
label carries, plus a total. Tags compare as numbers (D2 before D10). An
opening without a tag gets the next free D1 / W1 - K1 / P1 in Turkish - in
wall order; an explicit tag is never renumbered and a generated one never
repeats it. A value the model does not carry is an empty cell, never a default,
and Turkish output writes decimal commas.

draw_schedule reads the ACADMCP_ARCH records off the drawing through the one
reader rooms.py already has and draws a real TABLE the way the ISO 7573 parts
list does - top-left insertion, the table growing down, the parts list's 7 mm
rows and 2.5 mm text at the plot scale, the engine's representation reported.
Nothing to schedule, an unknown kind or language and more rows than one TABLE
takes are refused before anything is drawn.

arch_schedule joins arch_room and arch_rooms_detect under SECTION 25's rooms
marker (banner 3 tools), shares the TABLE command with entity_create_table and
bom_table, and the counts follow: 232 tools in 25 groups.

Live fix in com_backend.entity_create_table. MEASURED on AutoCAD 2026: IAcadTable
has no TextHeight property. pywin32 raised AttributeError on
`table.TextHeight = h`, the old code swallowed it, and every live table kept
the Standard style's heights (title 6.0, header and data 4.5), which is 0.1 mm
on paper at 1:50. The member that works is SetCellTextHeight(row, col, h),
probed on a scratch document: every cell read back 125.0 via
GetCellTextHeight. The row heights stayed 350.0 and GetBoundingBox matched the
reported bbox (10000,3250)-(15750,5000). Then draw_schedule ran end to end
through ComBackend on a scratch document: a native TABLE on A-SYMB-T-N for
doors (5 rows) and rooms/tr (6 rows, total 45,00 m²), and the document was
closed afterwards. The new fake in tests/test_table_leader.py has only the
measured members.

Umut CANandClaude Opus 5.5 b68fe7ef66 feat(arch): door and window symbols, straight/L/U stairs and the Blondel check
openings.py draws what stands in the gap the wall engine cuts, from the same
numbers - the wall axis, its face offsets and model.segment_of - so the symbol
cannot drift off its gap. A door is drawn open at 90 degrees: its leaf as long
as the opening is wide, square to the wall from the hinge on the swing-side
face, and a quarter arc from the closed position to the open one. swing=in is
the left of the axis (the inside of a CCW perimeter); hand names the hinge jamb
seen from the swing side facing the wall. All four swing/hand pairs are tested
against hand-computed hinges and arc angles. A window is a frame line on each
face and two glazing lines at the thirds of the thickness.

stairs.py draws every riser once as a line across its flight, the outline, a
walking line up the middle with an open arrow at the top, and the language's
'up' word on the first tread at 2.5 mm times the plot scale. An L or a U turns
on a square landing; its first flight carries (risers + 1) // 2 risers. The
riser count and every dimension are refused by name before any geometry.

blondel() reports 2R + G against 600-650 mm - the step-length rule attributed
to Francois Blondel (1675), reported as a design rule and never as a building
code: no national stair regulation is checked.

Umut CANandClaude Opus 5.5 a2996b0c95 fix(task-5): skip what the room reader cannot read, and one face carries one room
read_segments trusted any row with `points`. On a live seat an old-style
AcDb2dPolyline's Coordinates are x, y, z triples (measured on AutoCAD 2026,
2026-09-23: [200,200,0, 4200,200,0, ...]) which the backend reads two at a
time, so three closed ms.AddPolyline outlines on WALLS reported points like
[[0,0],[0,8600],[0,0],[8600,5400],...] and rooms_detect answered five faces of
2.6-6.9 m2 for two 20 m2 rooms. Headless, the same POLYLINE arrives with no
points and was dropped without a word; so were walls inside a block reference.
The reader now reads LINE and the lightweight polyline only (LWPOLYLINE, and
the live AcDbPolyline reported POLYLINE), and lists every other entity that
could bound a room in `skipped` with its handle, type and reason: arcs and
bulged edges as before, old-style polylines (2DPOLYLINE/3DPOLYLINE live, a
vertex-less POLYLINE headless), block references (INSERT / BLOCKREFERENCE)
and anything else not a line. Text, dimensions, leaders, points and hatches
bound nothing and are passed over. Re-run live on AutoCAD 2026 through the
real com_backend._entity_info rows: count 0 with the three polylines in
skipped (was 5 wrong rooms); with a lightweight pair and a block added, count
1 at 20 000 000 mm2 plus the block reference in skipped. The backend's stride
is left alone (shared file, other readers); this reader no longer trusts it.

label_room refused a reused id but not a reused face: a second label in a
labelled room (a retry after a transport timeout) wrote a second record with
the same area, which a schedule total counts twice. It is now refused before
anything is drawn, naming the record and label already there. rooms_detect
reports `labels` (every record in the face; `label` stays the first) and
`label_conflicts` for a face holding more than one.

No new ActiveX member is called.

Umut CANandClaude Opus 5.5 9e9138f22d fix(task-2): order-independent T cuts and bounded near-straight joins
A T recorded its cut on the crossing segment as a distance from that
segment's start; when the start was carried onto a third wall later in the
same pass the cut went stale, so [c,b,a] drew a free-end jamb inside wall a,
an uncut face and a double-hatched overlap where [c,a,b] was right. Cuts are
now stored as points and measured against the final axis.

A near-straight join whose faces are offset (a thickness or justification
change, or a rounding kink between such walls) mitred at offset/sin(kink):
faces 1e8 mm long and a clockwise region for a 0.01 mm rounding. A
straight-through pair whose mitre lies more than _MITRE_REACH (2) thicknesses
from the node now steps on the line bisecting the join - both sides of a
two-end node together, so the pieces tile without a sliver - and every piece
and hub ring is refused unless counter-clockwise, not only when it crosses
itself.

Pure geometry: no ActiveX member is touched, so no live probe applies.

Umut CANandClaude Opus 5.5 f5f11178a9 feat(task-8): SECTION 25 grid and symbols - arch_grid, arch_symbol
engineering/arch/symbols.py is pure: grid_prims() draws each structural axis on
the grid role - its CENTER linetype comes from the A-GRID-E-N row, no primitive
sets one - with a 5 mm (paper) bubble and its label touching both ends, on the
symbol role so the circle does not print dashed. Numbers run along x and
letters along y (A..Z, AA, ... none skipped) unless labels names them;
positions are sorted, duplicates and label-count mismatches refused by path.

symbol_prims() draws the four plan symbols: the north arrow (a circle, an
arrow turned CCW from +Y, the vocab(lang) north letter upright beyond the tip),
the section mark (the cut line, a labelled bubble past each end and a viewing
arrow at each end, p1/p2 relative to the origin), the level mark (the triangle,
its line and the value formatted +3.00 / ±0.00, with a decimal comma in
Turkish) and the elevation mark (a circle whose pointers are the tangents from
r*sqrt(2) touching it at +/-45 degrees). An unknown kind is refused with the
list, a parameter the kind does not take with the ones it does. Every size is
a declared paper-mm drafting choice times the plot scale, not a standards value.

arch_grid and arch_symbol draw through draw_prims with ARCH_ROLE_LAYER; alias
records (COLUMNGRIDADD, English and Turkish synonyms), a regenerated inventory,
the README snapshot at 233 tools and the branch-local group snapshot
(entity_creation 21) complete the registration.

Beyond the plan: grid_axes refuses a labels value that is not a dict and a
labels.x / labels.y that is not a list (a string was split into one label per
character, a number raised a bare TypeError). No new ActiveX member: a live run
on AutoCAD 2026 (scratch document, closed after) drew the grid and all four
symbols through draw_prims - A-GRID-E-N created with CENTER, bubbles, texts and
symbols on A-SYMB-T-N, the Turkish north letter K and the level "+3,00".

Umut CANandClaude Opus 5.5 afd42356b5 feat(task-7): SECTION 25 catalogue - arch_catalogue_list, arch_catalogue_insert
engineering/arch/catalogue.py is the standard-parts pattern of track B for an
architectural plan: twenty authored plan symbols in two families - thirteen
furniture items (single and double bed, wardrobe, three-seat sofa, armchair,
chair, dining table with four chairs, desk, kitchen counter run, fridge,
bookshelf, nightstand, coffee table) and seven sanitary items (WC, bidet, wall
basin, shower tray, bathtub, kitchen sink, washing machine). Every size is a
nominal catalogue dimension and says so in SIZE_BASIS, in each row and in both
tool docstrings; no standard is cited because none fixes these sizes.

Each item is typed block_define primitives on layer 0 inside [0, w] x [0, d],
origin at the back-left corner with the wall side along +X - a test holds all
twenty to their footprint. catalogue() searches name, family and the English
and Turkish labels, ignoring case and Turkish diacritics (buzdolabi finds
buzdolabı). insert_item() defines ARCH_<NAME> once, creates the furniture or
sanitary layer from its ARCH_LAYERS row when missing (live ActiveX refuses a
missing layer), inserts with an invisible ITEM attribute, and refuses an
unknown name with the nearest catalogue names before any write.

SECTION 25 opens on this branch with the two tools, alias records (INSERT,
ADCENTER, TOOLPALETTES and English/Turkish synonyms), a regenerated inventory,
the README snapshot at 231 tools, and the branch-local group snapshot
(entity_query 10, entity_creation 19) that the track F merge recomputes.

No new ActiveX call: insert_item composes the existing layer_list,
layer_create, block_list, block_define and block_insert members. Run once live
through ComBackend on AutoCAD 2026 (scratch document, closed after): all
twenty items defined and inserted, a second double_bed insert reported
defined=false, ITEM read back as double_bed, 20 ARCH_* blocks, 21 INSERTs on
A-FURN-E-N / A-SANR-E-N, both layers created at ACI 5 / 0.18 mm.

Umut CANandClaude Opus 5.5 67d578e09a feat(task-5): planar faces, measured room labels and the foreign-plan reader
engineering/arch/faces.py finds the closed faces a set of straight segments
bounds: endpoints within tol merge, every segment splits where another crosses
or touches it (the T-junction a partition makes), dangling edges are pruned,
and the half-edge walk turns to the next edge clockwise so every bounded face
comes out counter-clockwise. A piece nested inside a face of another piece is
a hole in it, so a ring of walls measures its body and a room with a column
measures its floor. Areas come from engineering.measure.polygon_area_perimeter,
the arithmetic analysis_measure_entity reports.

engineering/arch/rooms.py labels a room with the area of the face its point
lies in - a 4000 x 5000 room between 200 mm walls reads 20.00 m2, never the
axis area - and writes the room record onto the name text. Opening records
close door and window gaps along the wall faces, so two rooms either side of a
door stay two rooms. rooms_detect reads any plan's lines, drops faces under
min_area and thin wall bodies (mean width under 600 mm, a declared heuristic),
reports confidence 1.0 for faces enclosed only by our wall layer and 0.6
otherwise, lists arcs as skipped rather than flattening them, and never
modifies the drawing.

Two hardenings beyond the plan text, each with a test: read_records pages the
current space once and filters to the arch layers locally (the plan paged it
once per arch layer - twelve full scans, each a cross-process call per entity
on a live seat), keeping the same layer-then-drawing order; and an opening
record whose offset falls outside its wall (a stale record) is listed in
omitted instead of raising out of the read-only detector.

No new ActiveX member is called: both tools compose entity_list,
entity_get/set_xdata, layer_list and draw_prims, whose COM paths are already
live-verified.

SECTION 25 opens on this branch with arch_room and arch_rooms_detect under
the rooms marker; until Task 9 gives arch its group they file under
entity_creation and entity_query. Alias records, a regenerated inventory, the
README snapshot at 231 tools in 25 groups and the frozen group-size snapshot
follow.

Umut CANandClaude Opus 5.5 dae48d9037 feat(arch): the wall engine - L/T/X junctions, opening gaps and material poche
engineering/arch/walls.py turns a wall network - axis polylines with a
thickness, a justification and a material - into clean outlines. One rule
resolves every junction: at each node the segment ends are sorted by angle and
the left face of each meets the right face of the next one counter-clockwise.
That mitres an L, stops a T's stem on the crossing wall's near face (cut there,
while the far face stays one line) and cuts all four faces of an X. A T is an
axis end lying inside another wall: it is carried onto the crossing axis and
the crossing segment is split. The hub a three- or four-way node leaves is a
region of its own, so the poche has no hole.

Openings remove their width from both faces and are closed by jambs; a free
end is closed by a jamb. Each solid piece is one CCW region and one HatchArea
in the wall's material. The two face lines across each opening are kept as
thresholds - never drawn - so room_segments hands the face finder closed rooms
instead of rooms merged through their doorways.

Refused by name before any geometry: a duplicate id, an unknown material or
justification, a zero-length segment, a junction below 5 degrees, a corner
inside another wall off its axis, an end whose axis meets the other wall past
its end, a segment lying wholly inside the wall it joins, and one too short
for its junctions (engineering.measure.is_self_intersecting on its outline).
An opening that runs into a junction is returned in omitted, never dropped.

Every corner in the tests is hand-computed: two 200 mm walls at the origin
meet at (100, 100) inside and (-100, -100) outside.

Umut CANandClaude Opus 5.5 d5c5e90406 feat(arch): the plan model and its foundation - layers, materials, EN/TR, two generalisations
Track F starts here; the three group branches are cut from this commit.

- engineering/arch/model.py: Wall, Opening, Stair and Room as frozen
  dataclasses, and every refusal of spec 4 before anything is drawn, by path
  (walls[2].thickness): finite positive numbers, an axis of at least two
  distinct points with no zero-length segment, an arc segment refused by name
  rather than approximated, an opening on an unknown wall, past its wall,
  across an axis vertex or overlapping another (both ids named), an unknown
  material, and a typed room area - areas are measured, never typed. The
  plan travels as ACADMCP_ARCH XDATA; an opening's door/window kind and a
  stair's straight/l/u kind ride beside the payload kind as opening_kind /
  stair_kind, because one key cannot hold both.
- engineering/arch/layers.py: the arch set - thirteen ISO 13567-style layers
  with ISO 128 lineweights only (0.05 mm on the construction scratch layer,
  as every set in this repository) - and ARCH_ROLE_LAYER, the one place a
  role becomes a layer. Registered in engineering/layers.py last, which is
  what keeps the engineering.layers <-> engineering.arch import cycle closed.
- engineering/arch/materials.py: eight wall materials, one pattern each,
  every row citing its source: ANSI31 for brick (ISO 128-50 general hatching,
  acadiso.pat's own "Iron, Brick, Stone masonry"), AAC as ANSI31 at twice the
  spacing (a repository convention, and it says so), AR-CONC / AR-SAND as
  AutoCAD patterns, and the JIS A 0150 RC / stone / wood symbols. Reinforced
  concrete cannot be ANSI31 and AR-CONC in one HATCH, so it takes the one
  symbol that names it. Periods on a 1:50 sheet are recomputed from ezdxf's
  own pattern definitions by the tests. normalise_material is the one reading
  of a material name, shared by the model and wall_hatch, so the model never
  refuses "Reinforced Concrete" that the hatch table resolves.
- engineering/arch/lang.py: EN / TR vocabulary, D/W and K/P tag prefixes, and
  the decimal comma for lang="tr" (24,50 m2).
- draw_prims(role_layer=) and the XDATA codec's app_id= / kinds=: both
  generalised with the mechanical defaults, and the mechanical suite passes
  unchanged against them - that is the regression gate.

Umut CANandClaude Opus 5.5 b012fdf1be docs(plan): track F — 10 TDD tasks in three groups
Task 1 (main) lays the foundation every group branches from: the arch
layer set and role map, wall materials, EN/TR vocabulary, the plan model
with its ACADMCP_ARCH payload (opening_kind / stair_kind beside the record
kind), draw_prims(role_layer=) and the codec's app_id= / kinds=.

- Group W (Tasks 2-4): the wall engine (L/T/X junctions, opening cuts,
  poche), doors, windows and stairs, the async layer with read_plan and the
  exterior chains; SECTION 25 opens with four tools.
- Group R (Tasks 5-6): the planar-face finder, measured room labels, the
  foreign-plan reader and the door/window/room schedules; three tools.
- Group C (Tasks 7-8): the furniture and sanitary catalogue, the grid and
  the plan symbols; four tools.
- Final (Tasks 9-10, main after the W -> R -> C merge): arch_plan_from_spec,
  the three arch_* critique focuses, the arch pack and lean 64, then the
  v6 matrix with arch_roundtrip, four correctness checks, the live smoke
  and the docs.

Consistency pass: group W's poche now goes through draw_prims with the
arch role map (Task 1 resolves wall materials there), and the hedges on
Task 1's payload spelling and Task 5's rooms_detect shape are replaced by
the shapes those tasks pin.

Umut CANandClaude Opus 5.5 83f192ac2f docs: track F (architectural 2D) design spec — the plan model
One plan model — a wall network with hosted openings — and one engine that
resolves L/T/X junctions, cuts openings, hatches cut walls by material and
computes rooms as the faces the walls enclose, so areas are measured, never
typed. A pure planar-face finder reads rooms from foreign plans on both
engines (the live engine has no boundary_trace). Furniture/sanitary catalogue,
grid, symbols, exterior dimension chains, schedules from the model.

12 tools (SECTION 25, pack arch), English by default with lang="tr", poché by
material, three arch_* critique focuses, benchmark arch_roundtrip.

Umut CANandClaude Opus 5.5 2bba18d0f7 fix(com): hatch islands on a live seat — typed edges become temporary entities
hatch_add_boundary was refused on COM (hatch_edge_paths), so a transverse
section of any hollow part — a bushing, a flange bore — could not be drawn in
AutoCAD at all: draw_prims asked the capability map and refused up front.

ActiveX takes a loop as whole objects, which is not the same as "cannot take a
typed edge": each edge now becomes a real temporary LINE, true ARC or ELLIPSE
in the hatch's own space, appended with AppendInnerLoop, evaluated and
deleted. A loop that is only chained lines becomes one closed polyline — one
COM call instead of 180 for a flattened bore. The edge list is validated in
full first with the headless engine's messages; a loop AutoCAD refuses is
taken back out with its temporaries.

Measured on AutoCAD 2026 (25.1s), in scratch documents closed unsaved:
- a two-arc island leaves exactly 10000 - 100*pi (9685.8407) of a 100 x 100 hatch;
- the OD40/ID20 sleeve's transverse section B-B, drawn through the view engine
  and draw_prims, hatches 942.2864 mm2 — the engine's declared 180-gon;
- an open chain is refused (E_FAIL) and the entity count is unchanged.

hatch_edge_paths is now supported on both engines.

Umut CANandClaude Opus 5.5 e6f685643d fix(com): a DXF type filter finds what ActiveX names differently
block_find_references asks entity_list(type_filter="INSERT"), and ActiveX
calls a block reference AcDbBlockReference, so on a live seat the filter
matched nothing and every block reported zero references. Measured on
AutoCAD 2026 (25.1s): AcDbBlockReference, AcDbPolyline, and one class per
dimension kind (AcDbRotatedDimension, AcDbAlignedDimension,
AcDbDiametricDimension, AcDbRadialDimension, AcDb2LineAngularDimension,
AcDbOrdinateDimension).

entity_list and entity_count now let the DXF name find them: INSERT matches
BLOCKREFERENCE/MINSERTBLOCK, LWPOLYLINE matches POLYLINE, and DIMENSION every
*DIMENSION class. The reported type stays the ActiveX spelling, so a caller
already filtering by it is unaffected. Verified live in a scratch document:
two inserts, one dimension and one line are found by INSERT, DIMENSION and
LINE (the INSERT filter found 0 before).

Umut CANandClaude Opus 5.5 898e775f93 bench: matrix v5 adds mech_assembly; the correctness suite grows with the mechanical and sheet checks
The evidence for tracks B and G, in the shape tracks A and E used.

- benchmarks/tasks_v5.py: 18 tasks, DEFAULT_MATRIX = "v5"; v4, v3 and v2 stay
  addressable so an earlier report reproduces exactly rather than being only
  described. mech_assembly is roadmap criterion 3 - a flange-coupling sheet
  built from the part model and the sheet standard, through the code the
  tools call (apply_titleblock, draw_part/add_view/dimension_part,
  insert_std_part, extract_records -> draw_bom_table, add_balloon), gated on
  two numbers that cannot be negotiated: drawing_critique(focus=None) returns
  zero issues and the finalize score is at least 90 (it scores 100, 18/18 on
  the v5 matrix). The adapter returns the focuses that fired, so a
  regression names itself, and a test drops one balloon to prove the gate
  fails and names mech_bom_balloon_mismatch.
- Seven correctness checks (32 -> 39). mech_section_hatch_area is the one
  that cannot be faked: a sleeve of length 60, outside diameter 40 and bore
  20 cuts two faces totalling 1200 mm^2 exactly, read back out of the drawing
  through entity_measure. sheet_frame_iso5457_a3 pins the A3 frame (20,10 to
  410,287 inside the 420 x 297 trimmed sheet); mech_iso286_on_dimension pins
  40 H7 at +0.025/0 through the layout; std_part_iso4014_m12 pins s = 18 and
  k = 7.5 by value; mech_thread_unrepresented_is_caught is the seventh: a
  quality gate that never fires is not a gate.
- scripts/smoke_mech_com.py executed every new COM path once on AutoCAD 2026
  (25.1s): frame, title block, a sectioned shaft with 12 dimensions, an ISO
  4014 block with 1 ACADMCP_MECH chunk, a weld symbol, the parts list read off
  the drawing, a linked balloon, an xref attached / listed / detached, a
  31687-byte .dwg (AC1032) through ActiveX SaveAs, critique 0 issues, exit 0,
  every scratch document closed. It retries RPC_E_CALL_REJECTED (measured:
  the first call after Documents.Add is refused) and tracks its documents by
  the document list, since SaveAs renames them.
- Defects the evidence found, each fixed with a test that fails on the old
  code:
  * ezdxf dimension_diameter put the text beyond the SECOND chord point;
    ActiveX AddDimDiametric puts it beyond the first (measured live: a d50
    from (x,170) to (x,220), leader 10, text at (x,160)). Headlessly every
    front-view diameter stood on its own chain dimension. ezdxf now follows
    ActiveX.
  * draw_part's anchor goes on MECH; ActiveX refuses entity.Layer on a
    missing layer (measured -0x7ffdfff7 'Key not found'). draw.py ensures
    every target layer before the first entity.
  * bom.extract_records filtered on INSERT; ActiveX names it BLOCKREFERENCE
    (ObjectName AcDbBlockReference) - the live parts list was empty.
  * COM _entity_info reported no dimension text_position: ModelSpace.Item
    narrows to IAcadEntity, which has no TextPosition (measured
    AttributeError); read through _com_unnarrow (TextPosition measured on
    AcDbDiametricDimension, WCS). dim_overlap compared bbox centres and a
    diameter collided with its own bore.
  * pid graph raised KeyError 'start' mid-critique on a LINE whose point read
    AutoCAD refused while busy; such a line is left out.
  * the validator read "ISO 4014 - M12x60" as fake dimension text.
- The published A/B report is re-run over the grown suite rather than
  re-typed (26/39 -> 39/39, 13 fixed, 0 regressed), check_doc_numbers derives
  the task count from the v5 matrix, the token table is remeasured with a
  TOOL_PACKS=core,mech row (193 tools / 61,673 tokens), and the README's
  collected-tests figure is retaken (3990).

Umut CANandClaude Opus 5.5 3b033033f9 feat(mech): six mech_* critique focuses, the mech pack, lean 60, aliases and the counts
The four track-B/G branches are merged; this is the integration that makes the
25 new tools one surface instead of four.

- engineering/mech/critique.py: the six focuses of spec 13, dispatched the way
  the P&ID ones are. One index per critique run, shared through run_critique's
  context, so six focuses cost one read of the drawing; a drawing with no
  ACADMCP_MECH payload yields nothing at all, which is what keeps focus=None
  cheap for a P&ID sheet or a plain DXF. Each focus has a positive and a
  negative fixture.
  Two narrowings are in the module docstring rather than hidden:
  mech_view_misaligned checks the projection axis and not the quadrant,
  because the pinned payload carries no projection angle to check it against,
  and mech_duplicate_dimension catches two dimensions in the same place rather
  than a semantic restatement, because no engine exposes what a dimension
  measured.
- The index reads what the tools actually write, not only the plan's fixture
  shape. mech_part_draw anchors its part payload on a POINT (layer MECH) and
  lists every drawn view under "views"; the plan's index read INSERT/CIRCLE
  only and one "view" per payload, so it was silent on every part the server
  draws. It now reads POINT too, expands "views" into one entry per drawn view
  (the section check looks in the section's own WCS box, the alignment check
  compares frame_bbox centres), and pages entity_list instead of one call.
  Test: a part drawn by draw_part + add_view is read and passes all six; the
  same part with its hatch erased is reported.
- Live type names, measured on AutoCAD 2026 (2026-09-23, scratch document,
  closed): ObjectName AcDbBlockReference -> BLOCKREFERENCE, AcDbRotatedDimension
  -> ROTATEDDIMENSION, AcDbAlignedDimension -> ALIGNEDDIMENSION, AcDbPoint ->
  POINT with GetBoundingBox = the point. The index reads BLOCKREFERENCE as an
  INSERT and any *DIMENSION as a dimension; a wrapper test reports the ezdxf
  entities under exactly those measured names.
- mech_thread_unrepresented uses the view engine's own MINOR_RATIO, and checks
  the thin line ISO 6410 draws: the minor diameter of an external thread, the
  major of an internal one.
- mech_bom_balloon_mismatch: identical parts share one balloon (ISO 6433
  balloons a parts-list row), so a second M12x60 is covered by the first one's
  balloon instead of reported.
- TOOL_PACK_NAMES has "mech" (the 14 tools of SECTIONS 21-23). SECTION 24
  stays core: a frame, a title block, a parts list and an xref are universal
  drafting, not a vertical. Lean gains five and reaches 60 (54 with
  TOOL_PACKS=core).
- _GROUP_TAG_PRIORITY gains sheet directly after mech; the mech group label
  becomes "mechanical". SECTION 24's last four tools (xref_attach,
  xref_manage, image_attach, drawing_export_dwg) now carry the sheet tag, so
  group, pack and SECTION are one list: 229 tools in 25 groups, and
  engineering/blocks/entity_creation/drawing return to their pre-SECTION-24
  sizes.
- Ten golden tuning cases, two of them Turkish (with the diacritic spellings
  added to the alias records next to the ASCII-folded ones). The shared
  AutoCAD command set needed no change: the merge had already resolved TABLE,
  REVCLOUD, SECTIONPLANE, INSERT, ARRAY and SAVEAS, and nothing is stale.
- Inventory regenerated, the frozen group-size snapshot retaken from the live
  registry, and the README release-snapshot / pack / lean figures taken from
  scripts/check_doc_numbers.py rather than typed.

Umut CANandClaude Opus 5.5 5388440c27 fix(task-7): rotation honoured end to end, each view dimensioned once, refusals that name their path
- rotation turns the whole sheet of views about `at` as one rigid body: the
  prims, the recorded WCS `bbox` (plus the sheet-frame `frame_bbox` the next
  view is laid out against), the detail marker, and every dimension intent
  (points, text position, and the linear measuring direction + rotation).
  Measured headless: rotation=90 at (100,100) now draws (70,100)-(100,172),
  records exactly that box, and leaves only the 2 diameter chord defpoints
  off-geometry (was 4, up to 47.5 mm away).
- dimension_part dimensions only views whose record is not `dimensioned`,
  takes `views=[indices]`, refuses a view already dimensioned by name
  (ISO 129-1), writes the flag back, places the hole table once, and refuses
  a fit no target view claims before drawing anything. A view the dimension
  layer emits nothing for (a detail) is reported in `skipped` and left
  unflagged. mech_dimension_part gains the `views` argument.
- draw_prims checks hatch_add_boundary's {"ok": False}: the hatch is removed
  and the failure raised, never left solid through the bore. An engine whose
  capability map says `hatch_edge_paths` is unsupported (the live one) is
  refused before any prim of the view is drawn.
- a view scale other than 1.0 is refused by name in draw_part and add_view
  (views are drawn full size; the scale would only have been recorded).
- add_view's collision step compares real rectangles on both axes and steps
  along the projection axis layout_origin chose, so a third-angle view is
  never shoved back onto the front view and a top view keeps its alignment.
- draw_from_spec validates `at` / `rotation` into the `parts[i]:` path and a
  transaction that cannot open is a ValueError (a ToolError at the tool).

No new ActiveX member is called: the change composes existing contract
members (dimension_linear rotation, entity_delete, capabilities()).

Umut CANandClaude Opus 5 301610620c fix(task-14): detach an xref out of every space, and stop the live engine inventing facts
Three blocking findings on the refs group, all of them the same shape: a
number or a refusal the caller was entitled to read as measured.

1. ezdxf xref_manage: the victim scan and the `inserts` count both walked
   `doc.modelspace()` only, then dropped the definition with
   `delete_block(safe=False)` -- the flag that suppresses the in-use check.
   An xref shown on a paper-space sheet was reported as 1 insert where the
   drawing held 2, and detaching it left that sheet INSERT with no BLOCK
   behind it: `ezdxf.recover` reports `FIX 103 UNDEFINED_BLOCK: Deleted
   entity INSERT(#34) without required BLOCK definition` and the repo's own
   drawing_audit silently deletes the sheet geometry. The scan now walks
   `doc.blocks`, which is every entity space (model space, each paper-space
   tab, every block definition) and is exactly what ezdxf's own safe check
   searches with `doc.query('INSERT[name==...]i')` -- hence the
   case-insensitive name match. `delete_block` is now `safe=True`, as the
   plan's Interfaces block pins it, so a future miss raises instead of
   writing a corrupt file.

2. COM xref_manage(action='list') reported `kind: "attach"` for every row,
   a literal constant. Re-measured on this seat's registered type library
   (C:\Program Files\Common Files\Autodesk Shared\acax25*.tlb, "AutoCAD
   2025 Type Library", installed with AutoCAD 2026): IAcadBlock's xref
   members are exactly IsXRef, Path, Name, Reload, Unload, Bind, Detach,
   XRefDatabase -- no overlay indicator exists on the interface, so an
   overlay was reported to the client as an attachment. The row now says
   `kind: None`, the same honesty the adjacent `inserts` field already had,
   and the contract plus the tool docstring say so.

3. COM xref_attach had no duplicate-block-name guard, although
   contracts/refs.py and the tool docstring both promise the refusal and
   ezdxf implements it. Two different part.dwg files, or a re-attach after a
   repath, silently re-pointed or half-wrote the definition while the
   payload claimed the new path. Added `_block_names(doc)` (Blocks.Count /
   Blocks.Item(index) / block.Name -- the members xref_manage already walks)
   and the refusal fires before AttachExternalReference is dispatched, with
   the same message the headless engine gives. Lower-cased, because AutoCAD
   symbol-table names are case-insensitive.

Tests: five new ones, each failing against the unfixed backends -- an xref
shown on Layout1 is counted and detached with the drawing, the detached file
audits clean through ezdxf.recover, delete_block's in-use check is pinned,
the live listing reports kind None (against a fake that models only the
measured members, so it cannot enshrine an invented one), and the live attach
refuses a held name (xref and plain block, either case) without dispatching.

Umut CANandClaude Opus 5 8b14d4ef8d feat(task-7): SECTION 21 - the mechanical part model as six tools
engineering/mech/draw.py is the only module in the package that touches a
backend: it turns the pure engine's primitive descriptions into entity_create_*
and dimension_* calls, places them in WCS, and writes the part model back onto
the drawing as ACADMCP_MECH XDATA on an anchor POINT. It is not a contract
member and neither are the tools - exactly like gear_draw_* and
titleblock_apply_iso_a3, it composes the generic members, so it is written once
and works on both engines by construction and no capability key is needed. No
new ActiveX call was written, so there was nothing to probe on the live seat;
measured instead that every one of the 23 backend members draw.py calls exists
on ComBackend and that ComBackend has no abstract methods left.

mech_part_draw takes one model - a turned profile or a plate outline plus typed
features - and draws its views in first-angle positions (third on request),
dimensions them and records the placement. mech_view_add reads the model back
out of the drawing and adds a side, top, section (full/half/offset/revolved) or
detail view months later without the caller re-describing the part.
mech_dimension_part lays out ISO 129 dimensions with no overlapping text,
resolves ISO 286 fits against the measured nominal, and moves the holes into a
table past a threshold. mech_hole_pattern exposes the same expansion for a
drawing that was never built from the model - with its own diameter guard,
because Hole.validate needs a part and a standalone pattern has none.
mech_part_inspect reads the payload back and never modifies the drawing.

mech_part_from_spec draws a whole sheet inside one transaction. Every part is
validated before the transaction opens, so a refusal leaves the drawing
untouched and names the path (parts[1]: segments[0].d_outer: ...), and the
rollback is shielded with the shape engineering/pid/spec.py documents: anyio
cancellation is level-triggered, so a bare await in the handler would be
cancelled before the rollback body ran and leave half a sheet inside an open
transaction.

fits goes through dimension_intents(fits=...), the API Task 6 shipped, rather
than being stamped on at draw time: that is the path that validates a key by
name and refuses a fit on a reference dimension or on a hole that moved into
the table. It is scoped per view first - a fit on segment[0] names nothing in
the end view, and refusing there would make a correct three-view sheet
undrawable - and any key no view claimed is handed back to dimension_intents so
the refusal is written in its own vocabulary.

SECTION 21 registers the six tools in the new mech pack, with alias records
(SECTIONPLANE, ARRAY plus shop-floor synonyms in English and Turkish - mil,
kademeli mil, kama, pah, kesit, gorunus), a regenerated tool inventory, the
README release snapshot at 210 tools in 24 groups, and the frozen group-size
snapshot gaining mech: 6. Lean is deliberately untouched here: spec section 11
puts three of these on the lean surface together with group G's two sheet tools,
and Task 15 makes that edit once across all four branches.

Umut CANandClaude Opus 5 bd73b3a854 fix(task-6): a reachable ISO 286 route, a tolerance schema that refuses, a reference dimension
Three review findings, all root causes in `engineering/mech/dimension.py`.

1. The ISO 286 fit path was unreachable from the module's own pipeline.
   `resolve_tolerance` resolved `intent.fit` correctly, but nothing produced a
   DimIntent carrying one: no feature and no segment has a fit, and
   `dimension_intents` constructed every intent without `fit=`. Only a
   hand-built DimIntent - which is what the tests used - reached the code, so
   the spec's `mech_iso286_on_dimension` and the `mech_assembly` benchmark's
   "ISO 286 fits on the bearing seats" had no route.

   `dimension_intents(..., fits={key: code})` now stamps the code onto the
   intent its key names, and the part's own diameters became addressable one
   at a time through the new `segment_key(i, bore=...)` -> "segment[1]",
   "segment[1].bore"; a feature's stay addressable by id. A key that names
   nothing is refused with the names that exist, a malformed code is refused
   where it is attached rather than at draw time, a fit on a reference
   dimension or on one that already carries a tol is refused, and a fit on a
   hole whose diameter moved into the hole table (which has no tolerance
   column) is refused by name instead of vanishing. Task 7's planned
   `dimension_part(..., fits=None)` passes straight through - the argument is
   additive and keyword-only, so every call written against the pinned
   signature keeps working.

   The fit also now reaches the *text*: `intent_text` expands the `<>`
   placeholder and appends the code, so `text_rects` measures the string that
   is actually drawn and a hole that already names itself ("⌀6") keeps its own
   text and gains the code.

2. An explicit tolerance was silently discarded when `tol` omitted "mode".
   `mode = tol.get("mode", "none")` and `build_dim_override(0.05, 0.05,
   "none", None)` returns `({}, None)` without raising, so a ±0.05 resolved,
   echoed its own numbers back in the payload, and drew a dimension with no
   DIMTOL/DIMTP/DIMTM at all. `DimIntent.tol` now has a schema - {"mode",
   "upper", "lower"} and nothing else - validated by `_explicit_tol`: an
   unknown key, a missing "mode", a non-dict, and deviations under a mode that
   writes none are each refused by name. The mutual-exclusion guard reads
   `tol is not None` rather than truthiness, so `tol={}` is refused too.

3. The ISO 129-1 "no measurement twice" test was vacuous and the property was
   false. The old test built the key `_dedupe` uniquifies as the last step of
   `dimension_intents`, so it could not fail; meanwhile `style="chain"` emitted
   20, 40, 15 *and* 75 as four plain DIMENSIONs. `redundant_linear` now finds
   the span that shorter ones tile end to end on the same axis and level, and
   `dimension_intents` marks it as an auxiliary (reference) dimension - the new
   `REFERENCE_FORMAT` "(<>)", which renders "(75)". The plan's own test still
   holds (the 75 is present); it is no longer a fourth plain dimension. The
   error is one-sided on purpose: a tiling that is found is real, a tiling the
   greedy walk misses leaves the dimension plain, which is the direction the
   repository's critique rule wants. Baseline and ordinate parenthesise
   nothing, and two horizontal chains at different heights are not each other's
   pieces.

Tests: the vacuous gate is replaced by four that fail against the pre-fix code
- `redundant_linear` on the shaft's plain intents returns (3,) there and ()
here; the parametrised "a tolerance is either refused or reaches the dimension
variables" gate resolves the mode-less shape to an empty DIMVAR override
there; and `fits=` is a TypeError there. `_dedupe` is now exercised through a
duplicate fed in via the view's own dims, which the collector does not
generate itself. 46 tests in tests/test_mech_dimension.py (was 23).

Live AutoCAD: no finding was measured live and no new ActiveX call was
written - this module is pure Python with no backend, no async and no DXF. A
DIMTOL probe against the running seat was attempted twice and
`GetActiveObject("AutoCAD.Application")` blocked past the ~90 s contention
window both times, so the live engine was unavailable; no scratch document was
created (the probe never got the application object) and none was left open.

Umut CANandClaude Opus 5 3ef316d520 feat(refs): xrefs, raster underlays, data extract and real DWG output
SECTION 24 completes at eleven tools with xref_attach, xref_manage,
image_attach, data_extract and drawing_export_dwg, on the four contract members
that genuinely differ per engine -- backends/contracts/refs.py. Everything else
in the sheet track composes the generic members and is written once.

The ActiveX members were read off the AutoCAD 2026 seat's own type library
(C:\Program Files\Common Files\Autodesk Shared\acax25enu.tlb, "AutoCAD 2025
Type Library" 1.0, the library the running 25.x seat registers) before a line of
the COM path was written, and the measurement is in the code beside the calls:

  IAcadModelSpace.AttachExternalReference(PathName, Name, InsertionPoint,
      Xscale, Yscale, Zscale, Rotation, bOverlay, Password)
  IAcadModelSpace.AddRaster(imageFileName, InsertionPoint, ScaleFactor,
      RotationAngle)
  IAcadBlock: IsXRef (get), Path (get AND put -- so the repath is an assignment,
      not a method), Reload(), Unload(), Bind(bPrefixName), Detach(),
      XRefDatabase (get)
  IAcadDocument.SaveAs(FullFileName, SaveAsType, vSecurityParams)
  AcSaveAsType: ac2000_dwg=12 ac2004_dwg=24 ac2007_dwg=36 ac2010_dwg=48
      ac2013_dwg=60 ac2018_dwg=64 (=acNative)

The running seat itself was not answering COM while this landed (its window was
Not Responding and GetActiveObject never returned), so the type library -- which
is the same seat's declared surface and reads without a call into the process --
is what the members are measured from; no document of the operator's was opened
or touched. This repository has been bitten four times by a fake that invented a
member, so the COM fakes in the tests model those names and nothing else.
ActiveX angles are radians, so the degree-to-radian conversion happens at that
boundary and nowhere else.

Headlessly, ezdxf.xref.attach carries the attachment (measured on ezdxf 1.4.4:
block flags 20 for an attachment and 24 for an overlay, so "is this an xref" is
flags & (BLK_XREF | BLK_XREF_OVERLAY) -- masking BLK_XREF alone misses every
overlay), add_image_def + add_image the raster, with Pillow reading the pixel
size so the placed image keeps the file's aspect.

Three capability keys, declared in both maps:

  dwg_write  -- measured absent here (odafc.is_installed() is False), so the
                ezdxf entry is a runtime re-evaluation like viewport_render's
                matplotlib check rather than a hardcoded False: installing the
                ODA File Converter starts the call working with no edit to the
                map. The refusal names the install route and drawing_export_dxf.
  xref_live  -- reload and bind need a live seat's xref manager and are refused
                headlessly; list, detach and path are headless and are not
                behind the key.
  xlsx_write -- openpyxl is optional and absent here; CSV is always available,
                so the refusal never blocks the deliverable and says so.

Two numbers the plan predicted wrongly are corrected to what the registry
actually does. `block` outranks `drawing` in _GROUP_TAG_PRIORITY, so the two
xref tools file under `blocks` (9 -> 11) beside block_insert -- which is where
an xref belongs, being a block definition that lives in another file -- and
`drawing` moves 11 -> 12, not 11 -> 14. And `data_extract` must not say "parts
list" in its own text: that is the golden discovery query for
entity_create_table, and a file writer outranking the tool that draws the thing
is a regression the tuning bar catches. It is described by its destination --
a file -- instead.

Umut CANandClaude Opus 5 de8dc8f813 fix(task-13): read revision/balloon state from the space it is drawn on, and never at 200
Three findings, one family: a guard that reads the WRONG SET silently stops
guarding and the drawing gets a duplicate or a wrong number with no refusal.

1. Layout-scoped state was read from the wrong space. add_revision called
   read_revisions and add_balloon called read_balloons BEFORE enter_layout;
   both read entity_list, which follows the current space, so the guard
   inspected Model while the rows and balloons lived on the layout -- and the
   layout is the sheet workflow (sheet_frame and titleblock_apply both take
   one). Measured headlessly: two revision_add(rev="B", layout="SHEET1") calls
   both returned created=True, handles 46 and 5A, both bbox
   {min [230,273], max [410,287]} -- a second heading band and a second B row
   drawn exactly on top of the first, twelve TEXTs on the tab instead of six.
   Both reads now happen inside the entered layout, and the whole body sits in
   the try/ so the caller's tab comes back on the refusal path too.

2. bom_extract truncated the parts list at 200 INSERTs and printed a wrong QTY
   into a real TABLE. extract_records passed its own limit=200 default straight
   to entity_list, the tool exposed no limit, and nothing in the payload said
   the list had been cut: 250 bolts reported [("ISO 4014 - M12x60", 200)].
   all_entities now pages entity_list (offset loop, PAGE_SIZE 1000, plus a
   no-new-handles guard so a backend that ignored offset cannot spin) and
   extract_records(limit=None) reads the whole drawing. bom_extract exposes
   limit (0 = no cap) and reports truncated measured, by asking for one record
   past the cap.

3. The balloon clash guard did not fire in two routine cases. (a) targets is
   optional in the tool, so the clash test compared () != () -- False -- and
   two untargeted balloons carried item 1 with no refusal. The renumber arm
   above has already returned for the balloon that stands for these targets, so
   anything still carrying the number is a clash, whatever its targets; the
   message names the handle and says "no targets" when it has none. (b)
   read_balloons and read_revisions took entity_list's 200-entity default, so a
   drawing whose first 200 CIRCLEs are a hole pattern read back no balloons at
   all and every guard passed blind -- and index = len(existing) restarted at
   0, stacking revision bands. Both readers now go through all_entities.

Evidence, headless (ezdxf), each finding's own repro before -> after:
  1  created True/True, handles 46+5A, 12 TEXTs -> created True/False, one
     handle 46, 6 TEXTs; renumbered False/False -> False/True, same handle 33
  2  records 200, rows [(..., 200)] -> records 250, rows [(..., 250)]
  3a two balloons handles 2F+35, no refusal -> refused, naming balloon 2F
  3b read_balloons() == () with 206 circles -> the balloon past the 200th
     circle is found, the rerun renumbers, the item-1/BBB clash is refused
  3c 200 notes + rev A twice + rev B -> created True/False/True, row 1 then
     row 2 (was: every band at row 1, on top of the last)

Six regression tests added: one per finding plus the layout-scoped twin of
each, which is what would have caught all three.

The live engine was UNAVAILABLE for this round:
win32com.client.GetActiveObject("AutoCAD.Application") did not return within
90 s against the running acad.exe (PID 40068), and the ComBackend probe timed
out on its first call at both COM_CALL_TIMEOUT=60 and 180. No second AutoCAD
was launched and no document was opened. No new ActiveX call is introduced by
this fix -- it only reorders existing calls and pages entity_list(offset=),
which both engines already implement.

Umut CANandClaude Opus 5 01213fc5f5 feat(task-6): dimension intents, ISO 286 fits and an overlap-free layout
engineering/mech/dimension.py collects what the features asked to have
dimensioned, adds the part's own sizes (chain, baseline or ordinate for the
axial lengths, a diameter per segment and per bore, the two overall sizes of a
plate), and removes the duplicates - ISO 129-1 says each dimension appears once,
and a test asserts no measurement is placed twice.

Fits and tolerances are resolved through the modules that already own them:
engineering.fits for an ISO 286 code and engineering.tolerances for an explicit
ISO 129 tolerance, including build_dim_override's sign convention (the lower
deviation is passed as the magnitude of the minus side, exactly as
server.py::_fit_to_tolerances does). A H7 bore at 40 mm resolves to +0.025/0 -
the correctness check the spec names. A fit together with an explicit tolerance,
a fit outside the authored ISO 286 range, and a fit on an intent with no
measurable nominal are each refused by name rather than guessed.

The layout is the part that had to be measured rather than asserted: every
intent's text is turned into a rectangle by the same helper the test uses, and
an intent is placed on the lowest level whose rectangle is free, with the level
pitch clamped to clear the text whatever the caller passed. The test then
asserts the placed rectangles are pairwise disjoint - including on a crowded
plate and with a deliberately too-small step. That is the same property the
repository's dim_overlap critique focus checks on the finished drawing.

The plan's layout clamped that pitch to the text HEIGHT on every axis, which is
only the stacking direction for the row of dimensions under the view. Beside the
view the levels march in x, so the extent they have to clear is the text WIDTH:
measured here, three diameter labels are 9.45 mm wide (9.45, 5.6) at a 8.0 mm
pitch, so a shaft's three segment diameters - all on the y = 0 centreline, hence
all on different levels - overlapped by 1.45 mm. The pitch and the within-level
span are now both taken per axis from the same _text_size helper text_rects
uses, which makes the disjointness a property of the algorithm rather than of
the label lengths that happened to be in the test.

Over hole_table_threshold holes the per-hole diameters leave the view and become
a table instead, grouped by diameter, thread, counterbore and depth, one tag per
group and the quantity on every row.

Umut CANandClaude Opus 5 978c1075ad fix(task-5): cut faces on the real chord, cross sections that see features, a section with no dashed cut edge
Three defects, all of them the same mistake in three places: the cut face was
built from something other than the geometry it claims to show.

1. A prismatic cut face removed a feature by its BOUNDING BOX. `Hole.removal_box`
   is a square, so the gap punched in the cut face was the full diameter
   wherever the plane passed. On the plan's 80x50x8 plate with a Ho10 hole at
   (40, 25): a plane at y=29.9 grazes the hole (true chord 1.990) and the
   section still showed an 8 mm gap through solid metal - 560.0 mm2 hatched
   against a true 624.08, a 64 mm2 error in the hatched area AND a wrong drawn
   outline. `Slot` had the same obround-as-box. Features now answer
   `cut_spans(part, p1, unit)` with their own exact chord: `_circle_chord` for a
   hole, the union of two circles and a rotated rectangle for a slot, the
   polygon's own crossings for a pocket, and an exact slab clip of
   `removal_box` as the default. `_box_span` (the corner projection, which is
   the box's shadow and not a chord at all) is gone.

2. A transverse revolved section ignored every feature and the honesty rule
   never fired. A cross section through a DIN 6885-1 keyway came out as a plain
   hatched disc with `omitted == ()` - the commonest mechanical cross section
   there is, hatched straight over the 12x5 keyway. The face is now built by
   `_transverse_face`: its radii come from `radial_profile` (so a groove, an
   undercut, a bore or an ISO 6410 internal thread is in the face already,
   which the raw segment diameters could not report), a non-axisymmetric
   feature is asked for its own `cross_section` notch record, and one the plane
   really passes through with no such record is listed in `omitted` with its
   reason rather than hatched over. `Keyway._notch` is the one calculation the
   end view and the cut face both come out of.

3. A section drew its own cut boundary as a HIDDEN (dashed) line, because the
   longitudinal branch reused `silhouette_prims` and the silhouette draws the
   bore dashed - correct for an un-cut view, wrong for a section, where that
   line IS the hatch loop's boundary. ISO 128-50 bounds a surface lying in the
   cutting plane with a continuous wide line and ISO 128-3 leaves hidden detail
   out of a sectional view; via ROLE_LAYER['hidden'] this would also have put
   the cut boundary on the HIDDEN layer in Task 7. New `section_profile_prims`
   emits the cut outline all-continuous, and `half=True` keeps the dashed bore
   on the -Y half only, which is the half a half section does not cut.

And the claim the last commit made without earning it: the hatched area and the
drawn outline are now literally one calculation. The longitudinal loop is the
*emitted* outline flattened (`_flatten_path`), so a chamfer or fillet that
substitutes a silhouette corner is cut out of the hatch exactly where it is
drawn - a 2 mm 45 deg chamfer takes its 2 mm2 off the 1000 mm2 half face
instead of being hatched over.

Eleven new tests, every one of them red on the parent commit: the hole chord at
0/4/4.9 mm off centre, a tangent plane leaving the face whole, the 45 deg slot,
the keyway cross section against its own analytic area, the feature a cross
section cannot project, the feature the plane misses, the groove read off the
profile, the continuous cut boundary, the half section's dashed half, and the
chamfered cut face.

No new ActiveX member is called: all three fixes are pure geometry in the
backend-free `engineering/mech` package.

Umut CANandClaude Opus 5 72bd17d024 feat(task-5): sections, cut faces, material hatch and detail views
engineering/mech/views.py grows the two remaining view kinds. A section's cut
faces come out of the same radial profile the silhouette does, so the hatched
area and the drawn outline are one calculation and cannot disagree: a solid
shaft's half-section loop measures exactly the sum of its segment rectangles,
and a bore closes the loop on itself rather than being hatched over.

ISO 6410's section convention falls out of the model rather than being special-
cased: an internal thread's radial_edit already raises the bore to the major
diameter, so the hatch stops there. ISO 128-3's rib rule is a flag on the
feature - a pocket marked no_section_hatch is drawn and left unhatched, while
the rest of the cut face is hatched with the part's ISO 128-50 material.

Four styles, each either implemented or refused by name with the alternative
rather than approximated: full and half on a longitudinal plane through a
revolved axis; full and revolved on a transverse plane (the annulus, flattened
at 2 degrees - 0.015% of the radius, stated in CIRCLE_SEGMENTS rather than
hidden); full and offset on a prismatic part, where through features split the
cut face and pockets reduce it to the remaining thickness. A plane that misses
the part, or that grazes an outline vertex so its crossings cannot be paired, is
refused instead of producing a guessed cut face.

Details scale a circular region of a parent view, emit the ISO 128-34 circle and
letter for the parent and the "A (5:1)" label for the detail itself, and report
every feature that falls outside the circle in omitted - the honesty rule again.

Three test assertions were corrected to the measured truth rather than the
engine bent to them, each verified by running the code:

* the ISO 6410 test asked for the whole cut-face loop's minimum to be the M20
  major (r=10). It is not, and must not be: over the 5 mm that is drilled but
  not threaded the loop closes on the real 16 mm drill (r=8). The loop is
  ((0,10),(0,25),(25,25),(30,25),(30,8),(30,8),(25,8),(25,10),(0,10)). The test
  now pins both spans, which is the convention it meant to assert.
* the transverse-annulus areas were pinned at rel=2e-4. An inscribed regular
  180-gon is exactly 1 - (n/2pi) sin(2pi/n) = 2.0307e-4 under the circle, so
  2e-4 rejects the very flattening CIRCLE_SEGMENTS declares. The tolerance is
  now 2.1e-4 and the test computes the deficit and pins it, so the number is
  derived rather than guessed. CIRCLE_SEGMENTS' docstring now states both
  figures: 0.015% radial (the 2 degree chord's sagitta) and 0.0203% of area.
* tests/test_mech_views.py pinned VIEW_KINDS == ("front","side","top"), which
  this task deliberately grows. It now pins the three orthographic kinds as the
  first three and the full five-kind tuple.

_is_longitudinal takes only the plane; the plan's signature also took the part
and never read it.

Umut CANandClaude Opus 5 499b642fbd feat(sheet): revisions, the ISO 7573 parts list and ISO 6433 balloons
SECTION 24 grows to six tools: revision_add, bom_extract, bom_table,
balloon_add.

bom_extract reads. It walks the INSERTs through the generic members already in
the contract -- entity_list, block_get_attributes, entity_get_xdata -- and
returns parts-list rows from the ACADMCP_MECH std_part payload, falling back to
the block's own ATTRIBs and reporting which of the two each row came from. A
block with neither is skipped rather than guessed at, and the tool never writes
to the drawing.

bom_table draws the rows as a real TABLE, 180 mm wide (ISO 7573: the item list
is as wide as the title block), growing upwards from directly above it with the
heading row against the block and item 1 the row above -- which is what ISO 7573
asks for on a drawing. A TABLE is drawn downwards from its insertion point, so
the upward list is inserted a table height above its anchor with the heading as
the last row; one table_layout feeds both the real TABLE and the pure
table_prims, so the two renderings cannot disagree.

balloon_add draws the ISO 6433 reference -- numeral, leader, dot on the item --
and writes the balloon payload naming its targets. A rerun over the same
targets renumbers that balloon instead of drawing a second one, and an item
number already used for different targets is refused by name with the other
balloon's handle.

revision_add appends a row to the revision block, is idempotent per revision
code (a repeat draws nothing at all), and optionally clouds the changed regions
and tags them with the triangle. Clouds are refused up front, carrying
capability "revcloud", on an engine that has no revcloud member -- the COM
backend -- rather than leaving half a revision behind.

Declared: ISO 7200 does not standardise the revision block's geometry and
ISO 7573 does not fix the item list's column widths or row height, so both
reuse this repository's 180 mm / 7 mm ruling and say so in their SOURCE
docstrings. ISO 6433's "numeral at least twice the dimension character height"
is met by the numeral being 1.4x the balloon radius: the 4 mm default clears
2.5 mm dimension text, and balloon_add's docstring tells a sheet dimensioned at
3.5 mm to pass radius=5.0.

Three corrections to what the plan wrote, each measured rather than assumed:

* extract_records read `block_get_attributes(...)["attributes"]`. Both engines
  return the flat {tag: value} mapping itself (ezdxf_backend.py:6687 builds it
  from `ent.attribs`, com_backend.py:5703 from `ref.GetAttributes()` as
  {TagString: TextString}), so every attribute fallback would have been
  silently empty -- measured headlessly, where a PLATE insert carrying only a
  DESIGNATION ATTRIB extracted to nothing.
* draw_bom_table now reports `entity_type` / `representation` /
  `child_handles`. `entity_create_table` returns EntityInfo(type="TABLE") whose
  handle is the first CHILD of a composite on the headless engine, so reading
  that handle back gives a rule LINE, not an ACAD_TABLE -- the contract
  tests/test_table_leader.py already pins. A caller that means to edit the
  table afterwards has to be told which of the two it got.
* add_revision reports one `tags` entry per tag asked for ({at, handles}), not
  one per entity: a tag is two primitives, so a flat handle list claimed twice
  as many tags as the caller requested.

Discovery: `bom_extract` / `bom_table` / `balloon_add` each entered the index
heavy with "parts"/"list" tokens and took top-1 for the bare query "parts list"
away from `entity_create_table` (a BM25 tie broken alphabetically). Narrowed on
my side only -- the reader speaks of the bill of materials, the drawer names a
table, the balloon names an item -- never by touching the golden case.

Umut CANandClaude Opus 5 b2f858212f fix(task-4): the end-view occlusion rule, the double-drawn groove, the left view
Three defects in the orthographic view engine, all one missing idea: the engine
had no visibility rule and no single owner for the silhouette.

1. `_end_circles` inverted the hidden-line rule. Walking the bands from the
   viewing end it drew a circle only when its radius EXCEEDED everything nearer,
   and roled every such circle `hidden` unless it was the first band - so the one
   edge that CANNOT be occluded (a step face larger than the material in front of
   it) shipped dashed on HIDDEN, and the circle that really is covered was not
   drawn at all. `_front_max` is now the rule: an edge of radius r at station x is
   continuous when r is larger than every outer radius between x and the observer,
   dashed when it is not, and it is always drawn. Bores follow the mirror image -
   you see down a bore only while it stays at least as wide. Each distinct radius
   is emitted once, because two coincident circles are a duplicate entity.
   The same rule now roles a feature's axis-centred end-view circle, whose axial
   station comes from `removal_box`; a feature that reports none keeps its own
   verdict rather than having one guessed.

   Ground truth by ray cast along the axis of the same solid of revolution
   (segments 20x25, 40x30, 15x20; observer at +X, probe just inside each edge):
     r=10   at x=75 -> first surface x=75 -> VISIBLE  (was visible, kept)
     r=15   at x=60 -> first surface x=60 -> VISIBLE  (was HIDDEN, fixed)
     r=12.5 at x=20 -> first surface x=60 -> HIDDEN   (was not drawn, fixed)

2. Every axisymmetric groove was drawn twice - once as the notch
   `radial_profile` cuts into the silhouette, once by the feature's own
   `prims()`, which `_feature_layer` appended unconditionally. Six exactly
   coincident LINEs per grooved shaft, which is precisely what
   `critique.py::_check_duplicate_entities` matches, so premium rule 7 could
   never be met on a part carrying a retaining or O-ring groove. `_profile_owned`
   now drops a feature primitive that the body already emitted, and drops a
   revolved front view's `visible` silhouette line from any feature that edits
   the radial profile: the spec's rule is that grooves cut a notch in the
   silhouette, and the notch belongs to the one calculation. Suppression is
   "the profile already drew this", not "this feature edits the profile", so a
   blind bore keeps the bottom line the profile cannot express, and an internal
   thread keeps its ISO 6410 limit line.
   A groove straddling a step was worse than duplicated: the feature reads one
   surface radius for a span that has two, so it drew a groove floor through
   solid material and left the +Y path with four odd-degree nodes. It now has
   two - its two ends on the axis.

3. `build_view` validated `side` and put it in ctx, but the prismatic branch
   ignored it: `side="left"` returned the right-hand view, with every feature on
   the wrong side of the sheet and a symmetric outline rectangle to hide it. An
   observer at -X sees screen-right = -Y, so the feature layer is now mirrored
   about the outline's mid-Y. The top view is always seen from above and does
   not move with `side`; that is now said in the docstring and pinned by a test.

Tests: the two that pinned the inverted rule are rewritten around the ray cast,
and one of them contradicted its own name. Seven tests added, and the prismatic
side-view test's hole moved off the y=25 mirror axis, where it could not tell a
left view from a right one. Nine of them fail against the previous `views.py`
and pass against this one.

Live AutoCAD was unavailable for a SOLPROF cross-check: the running AutoCAD 2026
(pid 40068) reports Responding=False and `GetActiveObject("AutoCAD.Application")`
never returned inside 100 s, so no scratch document was created and none is left
open. No new ActiveX member is called by this change - views.py is pure.
