Tested the tempting explanation for the last 51 -- that _l/_dead variants share
their base's vertex and index counts, making them mutually confusable and
adjacent so locality cannot help. It is FALSE: 2714 variant/base pairs across
every container, and exactly zero share identical counts.
What is actually happening is better news. e010_bdy_01_l is 171 verts / 90 tris
and NO other resource in its container shares those counts, yet in Stage_S02 and
S26 it decodes to 1600x2100x4800 -- the same bounds e303_wep_01 (172/110)
produced before the fix. Differently-shaped resources land on the same place, so
the attractor is a region of round axis-aligned box data that validates for many
(vtx, idx) shapes at once, not "another mesh with my shape".
That also explains why the neighbourhood fix helped so broadly: it steers
resources away from one strong attractor rather than resolving many pairwise
confusions.
Candidate next step recorded with its risk: de-prefer candidates whose sampled
positions are all multiples of 50 with a large span. It must be a TIEBREAK
between validating candidates rather than a rejection -- an earlier sweep for
that signature also flagged legitimate e_rou_* composite proxies -- and it needs
the same gate (decoded must not fall from 5480).
