# Interior-O courtyard / light-well seeding A/B (ld2, DESIGN.md §13.6). The erc
# crinkliness residual is dominated by LANDLOCKED rooms (seed probe: every
# crinkliness fail is under-exposed crink<0.62, none over-exposed) — rooms with
# no plot facade and no uncovered-O neighbour, so area_outside ~ 0. The current
# adjacency-aware seeder places ONE O on the most PERIPHERAL leaf, where adjacent
# rooms already have facade, wasting it. This arm instead seeds O as INTERIOR
# light wells (most-landlocked leaves first) and scales their count with the room
# count (outside_divisor=3). Seed probe (bal+share stack): harbor 147->129,
# maple 219->206 total fails at odiv=3 — but the lever ADDS leaves (harbor +4,
# maple +8), so the §13.4 risk is the seed advantage washing out under search.
# This A/B answers whether it survives to convergence.
#
# Both arms hold the current default stack LEAFSHARE=1 (factor 3) + DEPTHBAL=1
# (the §13.5 winner). The control arm is interior-OFF (peripheral O) — must
# reproduce §13.5 bal+share (maple 82.3, harbor 40.0); the experiment arm adds
# INTERIORO=1 (odiv=3). Seeds 0/1/2, two programmes, 20000 native evals, staged.
