The map is now a torus - walk off any edge and reappear on the opposite
side, no edges or corners. A new Toroidal helper carries all wrap-aware
distance/direction/movement math, and every position comparison in the sim
routes through it: soul pressure, node + structure sensing, gift/teacher/
neighbor scans, bonding, movement, the spatial grids (NPC and node cell
index both wrap their bucket lookups at the seam), and town centroid
(averaged in anchor-relative deltas, since averaging raw coordinates across
the seam is meaningless).
Towns re-laid as a 2x2 even grid on the torus (quarter/three-quarter points,
320 & 960 on a 1280 world): every town sits exactly 640 units from each of
its two axis-neighbours in all directions, wrap included - no more edge-boxed
North/South that could only forage inward. World grew 1152 -> 1280 with
resources scaled to area.
Verified over a 240-day soak: all four towns alive and balanced (pop 23-25),
population stable ~96, 119 bonds (27 cross-town), cultures still diverge, and
wrapped distances correctly cap at the torus half-diagonal (no false
across-seam blowups). 183s headless.

World scaled 3x (768x768) with all four towns at compass points, each
running its own soul culture: North generational, South nature, West
materialist (new profile), East selfish. Two new resources: Ore (metal
tier) and Herb (medicine - mends health, reason to forage, trade good).
Spatial hash grid replaces O(n^2) proximity scans (soul pressure,
neighbor, teacher) - 3.6x headless speedup at ~80 NPCs. First social
verb beyond work: pair-bonds - settled adults who keep warm company pair
up; warmth now accrues from proximity not only gifts; bonds break at
death. Reproduction deferred (bonds-first per plan).
The four-town thesis fully realized on one engine (240-day run):
North know 1.27 clean, South nourish 0.85 clean, West prosperous but
debris 0.23, East hungriest 0.60 and lowest knowledge 1.08. Positive
cultures stay soul-clean, negative ones carry real debris, all from
behavior weights - nothing scripted. 99 bonds, 80 deaths, four living
societies.
