Wire the centered relational-neighborhood geometry (engram_geometry.c) into
activation seed selection behind a reversible env flag that defaults OFF. Flag
unset => byte-identical to M8 (verified: identical result id sequence + order
across 15 queries vs the M8 baseline binary). When set, composes with M8's ANN
candidate generation: damp-only seed reweight by centered membership
(disambiguation) + sub-threshold neighborhood priming (warm floor below the WM
gate, capped, ISE-skipped). Safe because the BFS keeps the max, so priming only
raises a floor and can never cap a legitimate activation.
Descriptor + global mean run over the paged store; the resident-array vindex is
bridged with a vids[] map. Tunables via env (SEED_LO/PRIME_SCALE/PRIME_MAX).
Default-OFF binary is behavior-neutral and safe to deploy. Enabling the flag is
currently NO-GO on cost/benefit: 3.2x median / 13x p90 latency for no reliable
coherence/disambiguation gain (see perf profile). Not a defect - WM cap holds,
no crash, ASan/UBSan clean.
