Owner correction (chat, 2026-08-27): no flat chamfer at the tip — a plain
sharp apex. Proven by execution on the issue fixture: the outset contour fell
back to a two-point bevel (the 4·h mitre limit against an 87 cm reach) while
the inset contour folded into a bow-tie, and subtracting that fold carved the
V-notches — together they made the trident. Now a degenerate corner (below 15
degrees, inner faces meeting inside both walls) contributes ONE outset point
at the plan's own vertex — no bevel, no metres-long mitre needle — and its
inset is clipped at the convergence line so no fold is subtracted. Plain and
merely sharp pairs keep the full mitre of #310. The write-side limits of
П1-П5 stop new plans from creating such corners at all.

The owner's five limits as pure functions: minimum 15 degrees between
neighbouring rays of a node (a straight wall through the node is a 180 pair,
not a violation), at most 6 walls per node, a segment at least
max(20 cm, its own thickness), 5 cm clearance between non-incident nodes and
between a node and a foreign wall (a T-joint sitting exactly on that wall is
incidence, not a near miss), and a room interior of at least 25 cm2 after the
masonry is subtracted. Thresholds are absolute and do not scale with cell_cm.
newViolations() implements the spec's inheritance boundary: only violations
introduced by the write are reported.
