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.

"""The synthetic plant pair: a schematic P&ID and its layout, with known answers.
|
||||
|
||||
Every track H reader is measured on this pair and never on a client drawing
|
||||
(spec §14). It reproduces each field finding of the design spec (§1, §15) with
|
||||
invented names and invented numbers:
|
||||
|
||||
* **Tags in both drawings** - T101..T104, M11, CP-1 in room 1; T201..T203, M12,
|
||||
CP-2 in room 2. T105 is on the P&ID only, so the run to it is not routable.
|
||||
* **The P&ID is not to scale** - room 1 is the layout stretched 1.3x about the
|
||||
origin, room 2 is rearranged outright. The generator computes the scale
|
||||
statistics of its own placement (pairs at least 2 m apart, the ratio of their
|
||||
distances, the share within ±10 % of the median) and refuses to write a pair
|
||||
that would not read as ``schematic``.
|
||||
* **Service layers in English and Dutch** - ``P_product piping``,
|
||||
``P_cipsupplyline``, ``P_cipreturnline``, ``P_ijswater`` (ice water, a utility
|
||||
outside the default takeoff scope), valves and the reducer on ``KLEPPEN``.
|
||||
* **Russian supply / return words** - ПОДАЧА beside the CIP supply runs,
|
||||
ВОЗВРАТ beside the returns, and one return (``CR2``) drawn on the *supply*
|
||||
layer: only the word says which way it runs.
|
||||
* **Size labels as drafters write them** - ``{\\fArial|b0;Ø51}`` (an MTEXT format
|
||||
run), ``Ø51``, ``%%c38``, ``\\U+2205 38``, ``⌀38``, ``ø38``, ``SMS51``, ``DN20``,
|
||||
``DN25``, ``20x27``; each 300 mm from the segment it names and at least 600 mm
|
||||
from every other run (the generator checks it).
|
||||
* **Fittings on runs** - a reducer (``VERLOOPSTUK``) between Ø51 and Ø38 on
|
||||
``PR3``, inline valves (``KLEP_VLINDER``) on ``PR2`` and ``CS2``; the pipe stops
|
||||
at each fitting's box and continues on its far side.
|
||||
* **A double-drawn segment** - on ``PR2`` a LINE lies exactly over an LWPOLYLINE
|
||||
segment; it must count once.
|
||||
* **Electrical texts in Russian** - power, phases, voltage, N and PE, ЧРП (VFD)
|
||||
1500 mm right of each load's tag; the heater on T202 states no power.
|
||||
* **The layout lies about its units** - ``$INSUNITS = 1`` (inches) over
|
||||
millimetre geometry; one stray LINE 5,000 km away; two copies of the plan
|
||||
100 m apart, so every tag is on the layout twice and is unique only within a
|
||||
copy.
|
||||
* **Rooms** - wall outlines (200 mm walls) and labels ``ROOM 1 PROCESS HALL`` /
|
||||
``ПОМЕЩЕНИЕ 2 МОЙКА``; ``Wiring to CP1`` style MULTILEADER callouts from each
|
||||
load to its panel, in four spellings.
|
||||
|
||||
Truth values are **computed here from the positions placed here** - Manhattan
|
||||
distances, the rectilinear minimum spanning tree of each run's tags, the cable
|
||||
lengths rounded up after the allowance - never typed. A position on the layout
|
||||
is the insertion point of the tag's TEXT, which is also the centre of the
|
||||
equipment circle it labels, so "the tag's position" and "the equipment's
|
||||
position" are one point by construction.
