# A3 — Route Lengths Typical-Range Table
# Per Operating Principle #11: per-project, context-reasoned typical ranges with basis disclosed.
# NOT a single global "30 m default" — values reasoned per cable context.
#
# Source basis: ANNEX_A 13002/3/4 (Electronics Site Dev Plan Layout Parts A/B/C, 150 DPI render visual estimation)
# Method: visual estimation against the depot site footprint (~600-800m long axis × ~150-300m wide)
#         with per-zone tier classification. Calibration: ±20% pending site survey post-NTP.
# Customer-facing disclosure: cable lengths estimated by context tier; refined at site survey.
