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withdrawn.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.
Will waived diff review -> build it for real. Add engram_boundary_beat() to the
runtime (afferent counter++ + engram_chrono_tick + engram_strengthen(self-anchor)
+ dharma_emit) and two act-stats counters (aff_boundary_ops, dharma_emits).
codegen cg_fn injects ONE engram_boundary_beat(op) at the entry of every
@manager/@accessor fn (fn_has_decorator, so it fires under @route @manager too) —
a decorated op self-reports with ZERO hand-written instrumentation. Rebuilt elc
self-host + the cognition engram in the worktree; ran it as the clone daemon on
:8900. Proof (/api/boundary-proof, @manager, empty body, 5x): aff_boundary_ops
0->5, dharma_emits 0->5, self activation_count 1510->1513, chrono stamp advanced.
Brought in feat/cognitive-architecture engram runtime+server for the build.
strengthen = activation bump (not content/edge write) -> identity protection
intact. Live :8742 untouched; no push, no cutover.
