Neuron	7a1501d097	Grounding is the edge's weight, and the weight is a vector ... A relation that keeps holding up strengthens; one that stops corresponding decays. That is not analogous to grounding, it IS grounding — so it belongs on the edge, not in a subsystem beside it. The graph was already the grounding structure; this stops modelling it as something else. Deleted, not refactored: - cog_ground_edge and the `grounded-by` relation type. A grounded-by edge models grounding as a relation BETWEEN nodes when it is a property OF a relation. #147 fixed which endpoints that edge landed on and left the wrong idea intact. Measured on the live store: the old path scored two nodes with ZERO edges between them at 0.925237 and wrote an edge for it. - ground() writing. It was a read that wrote — the eg_vindex_sync defect. Three identical calls produced three writes to the same edge id. - keystone_write_blocked. Its measured cost was 0.00% brier reduction over n_trials 0 on the keystone: the loop never ran, so the self was never calibrated and never falsifiable. Nothing replaces it — non-circularity of the reference frame is temporal, not a permission. - a graph predicate for "evidence downstream of itself", built and then withdrawn. Reachability from the self region covers 89.2% of the live graph (10,580 of 11,861 nodes), so any topological predicate marks nearly all evidence tainted and degenerates into the total block censorship began as. The vector, carried in a GRD1 block on the edge's own metadata: factual, relational, associative (the existing hebb), polarity (SIGNED — near zero is "no support", negative is "actively contradicts"; `inhibitory` is that distinction crushed to one bit), provenance class, and a timestamp. Confidence, recency, staleness and volatility are DERIVED at read and never serialized. Decay is one model, not two: cog_decay_factor is the single implementation and engram_temporal_decay now delegates to it — proven bit-identical over 24 (age, reinforcement) points. Values reference: thirteen regions, aggregate MIN, binding value named. Measured — the 13 have pairwise centroid cosine min 0.1525 / mean 0.5199 / max 0.9278, so they demonstrably are not one region, and a mean would let agreement with twelve mask a violation of the thirteenth. Supersession versions the whole vector jointly, gated by consequence and salience with no epsilon anywhere: floor crossings and sign changes only. Polarity flips and provenance-class changes are inherently significant and bypass the salience gate. Also fixed: the frame contract. Descriptors are built over L2-normalized member embeddings; think() and the grounding path were fitting RAW vectors against them. Measured on the self region, same data, same 106 members: magnitude 0.00283443 -> 0.536134, spread 18.7565 -> 0.930163. Every fit score sat three decimal places below the 0.5 floors that gate on them. assert() gates on both floors and computes still_held instead of returning a hardcoded `true` — the old build reported still_held for a node that does not exist.	2026-08-16 13:18:50 -05:00
