The takeoffs were run again on a real P&ID pair (kept outside the repository)
and compared with the hand-made workbooks. The user chose how three gaps
should close:
- Rooms drawn as frames. A room label that no wall face holds takes the
smallest closed, straight-sided polyline around it, provided it holds no
other room number and is at least ten label heights a side (label+frame,
0.8). A P&ID draws its rooms this way, so P&ID lengths are now cut at the
frames rather than sent to the nearest label. An unnumbered mention inside
a frame ('hot room') does not deny it.
- The nearest panel, flagged. cable_takeoff(panel_rule="nearest") is the
default: a load that no callout places takes the nearest panel on the
layout, among names with a panel prefix (is_panel_name: CP, JB, DB,
MCC ...) or names a callout gives. The row is flagged panel_inferred, and
an inferred panel never makes a package. panel_rule="stated" keeps the old
behaviour. The takeoff_roundtrip gate and the cable correctness check read
stated panels only: a guess is no evidence.
- Possible packages and detail copies. pipe_takeoff reports detail_copies:
compact groups of tags drawn twice (repeated), and compact groups of one
equipment's own parts, such as M150B, M150C and M150D of M150 (family). A
vendor package or an equipment detail shows up this way. Nothing is
removed until exclude_regions names a region. The runs left out go to the
control rows as excluded_region and to excluded_m. The workbook's method
sheet names the regions.
Each change has a synthetic test that failed first. Suite: 4986 passed, 1
xfailed. The inventory and the document numbers match (README: 4987
collected).

pipe_takeoff merged line ends closer than tol = 1.0 drawing units and
silently dropped any segment shorter than that. On a millimetre P&ID that is
1 mm. On a metre drawing it is a metre: ends a metre apart were merged and
every pipe under a metre disappeared from the totals, with no warning. The
review of the network engine found this.
- tol now defaults to 1 mm in the unit the P&ID's geometry implies: 1.0 on
a millimetre drawing, 0.001 on a metre one. A tol the caller gives is
used as given.
- build_network counts the segments that collapse to a point
(stats.segments_below_tol), and pipe_rows turns a non-zero count into a
warning naming the tolerance.
A new wire test builds a metre P&ID with a 0.6 m pipe and a 5 m pipe. Before
this change the takeoff said 5.0 m; now it says 5.6 m. The network test
checks that a sub-tolerance stub is counted. Registry, packs, aliases and
every track H suite: 472 passed. The inventory matches the live surface.

cable_rows reads each load's power, phases, voltage, neutral and VFD from the
P&ID's electrical texts near its tag, and its panel from the layout's wiring
callouts (else the P&ID's), names normalised CP 1 -> CP-1. The length is the
Manhattan distance on the layout from the tag to its panel, and the cable
ROUNDUP(length x (1 + allowance)) to the metre, on the length rounded to
1e-6 m so binary noise never buys a metre. Power is never invented: a load
with no stated kW keeps an empty cell and an open item. Without a layout the
lengths stay empty with an open item per row. Room and panel totals count a
panel package's power once, never its children's as well; the rule is on the
method sheet. Sections only from the caller's section_rules - no standard
table exists here.
The workbook gains the cable shape (Metraj, Ozet by room and panel, Kontrol
as the open-items list, Metodoloji) in the same three languages;
cable_takeoff joins SECTION 27. Inventory regenerated; README snapshot 243
tools (238 advertised); registry snapshot analysis: 14.

write_workbook builds the user's takeoff workbook from a result: Metraj (rows
with direct, continuity and unassigned lengths split, the allowance as its
own column, routed / unroutable / grand totals), Ozet (by service, diameter
and room), Kontrol (unassigned diameters and unroutable runs with the
reason) and Metodoloji, generated from the result: sources, the length
source and why, the scale-check verdict with its statistics, the units,
every rule and tolerance, and every warning. Headers and sentences in
Turkish, English or Russian. CSV always, one file per sheet; XLSX with
openpyxl, otherwise the xlsx_write refusal naming the office extra while
the CSV files are still written.
pipe_takeoff reads the P&ID and the layout once each (take_snapshot),
computes in a worker thread and never modifies either drawing. Tagged plant
and analysis; the plant pack is the integration task's. Alias record in
English, Turkish and Russian. Inventory regenerated; README snapshot 242
tools (237 advertised); registry snapshot analysis: 13.
