No pattern-to-station data exists in the drawings. Per user decision
(2026-10-21) the modelled range 4+745..5+480 is split into 2 m segments with
arbitrary pattern names, marked placeholder in CSV, meta and viewer, to be
replaced later. Ring step reduced to 1 m so that the 2 m segments align.

No station range is written next to pattern names in 03-003..008; the pattern
names appear only in file names. 04-006..008 name WL/RP zones at the portals
without stations. Pattern-to-station mapping is left open, not inferred.

build_skeleton.py sweeps the confirmed standard section (R6982 inner, 300 mm
lining, R7402 excavation, crown 6.615 m above road) along the centreline for
4+745..5+480, road = 계획고, ground = 지반고 band. Walls and invert are
approximations and recorded in meta. Verified: inner radius identity, crown
height, chord length 799.9 m for 4+700..5+500. Viewer uses three.js 0.160.0.

Table 1 (R1..R3', phi1/phi2) and table 2 (A..K, 라이닝 두께 300) are parsed by
S(%) rows +3..-3. R1=6982, R3'=4699, R2'=3910 match the arc list; lining
thickness 300 mm matches the concrete arc band. Units of a..f and the
cross-slope station ranges need HITL confirmation.

Concrete major arcs R7282/R6982 (same centre) give a 300 mm lining band
and excavation R7402 sits 120 mm outside the outer lining arc. Table cells
(CS-TABL-TEX2) meaning is left to HITL.

A single regression over 4+740..5+480 gives 2.39%, which hides that the grade
is 2.491% up to 5+300 and drops after it (likely a vertical curve, [추론]).
Segment grades are now reported; no value is adjusted.

Applies the 2026-10-21 decisions: A column = GL, B column = design grade,
20 m station numbering, gaps marked [미확정]. Regression slope of the grade
column is compared with the drawn S=2.4913%. No value is adjusted.

Ruler 4+740..5+480 (38 stations, 20 m). Two decimal series per station:
A (|across|~33 m) varies with terrain; B (|across|~16 m) rises ~0.498 m per
station (2.49% grade). Series naming and the ruler scale (chord ~21.27 m per
20 m station) are left to HITL. Output is a draft; no value is adjusted.

Shows CR-TABL-TEX2 carries the same positions with different decimal values
between sheets (e.g. 63.938 vs 65.969), consistent with differing ground
levels. Interpretation of the 740.00~980.00 ruler is left to HITL.

extract_alignment_plan.py takes the midpoint of each station's two side
ticks (CA-ALGN-STSM) as the centreline point. Sheet 001 gives 4+700..5+500
with consecutive residual <= 0.02 m. Sheet 002 gives identical output, so
the duplicate question is left to HITL. Profile EL is not yet extracted.
