will.anderson 5f6ce5ca1f M-INTEROCEPTION P1: two-threshold consolidation layer (ENGRAM_CONSOLIDATION, default OFF)
The co-activation accrual already works (hebb is an EWMA over co-firing); what
was missing is the promotion layer from design §9 that turns accrual into
durable structure. This adds it on top, entirely behind ENGRAM_CONSOLIDATION so
the OFF path is byte-identical to trunk.

CONNECTION threshold ("connection IS consolidation"): when a strongly-firing
InternalStateEvent is created (salience >= ENGRAM_CONSOL_CONN_MIN, default 0.6),
wire hebbian-associate edges from it to the top-K working-memory nodes active at
that instant (ENGRAM_CONSOL_WM_TOPK, default 5), provenance-tagged
"consolidated-from-ISE" and dedup-guarded. A sub-threshold ISE forms nothing (a
shower thought) and drifts out at the existing 48h prune.

PERMANENCE threshold (rare): engram_consolidate_permanence(node) marks a node
whose rehearsed ACT-R base-level clears ENGRAM_CONSOL_PERM_MIN durable via a
reversible metadata marker; engram_prune_telemetry then exempts it (gated, so no
trunk node is ever affected). Idempotent, no double-promote.

Thresholds are env-tunable for A/B without a rebuild.

MEASURED on a copy (throwaway HOME):
- Headline accrual curve (flag OFF, pure trunk) over N co-activations of a wired
  pair — hebb_max: N=1 -> 1e-4 (=ETA), N=100 -> 0.010, N=1625 -> 0.150
  (LINK_MIN, where an unwired pair consolidates), N=3000 -> 0.259; tracks the
  analytic EWMA 1-0.9999^N within measurement noise (co-activation P~1).
- Strong ISE wired 2 edges to exactly the wm_top nodes (hebb-a, hebb-b); weak
  ISE formed 0; edges carry the reversible provenance marker.
- Promoted node survived the 48h prune (2->1 nodes); ephemeral ISE swept.
- Flag OFF: ISE creation added 0 edges, permanence returned 0 (no-op).
ASan+UBSan clean.

/* test_interoception_p1_consol.c — M-INTEROCEPTION Priority 1.
* Two-threshold consolidation (ENGRAM_CONSOLIDATION, default OFF).
*
* Modes:
* accrual — flag OFF (pure trunk). Drive N co-activations of a WIRED pair and
* print act-stats at sampled N so the run script can plot the
* hebb accrual curve (headline measurement). No consolidation code
* runs; this measures the EXISTING EWMA accrual.
* connect — flag ON. Seed, activate to populate WM, then create a STRONG ISE
* (connects to wm_top) and a WEAK ISE (below the bar → nothing).
* Exports the graph so edges from each ISE can be counted.
* perm — flag ON. Load two OLD InternalStateEvent nodes; promote one to
* permanence; prune telemetry; export so the durable one is shown
* to survive while the ephemeral one is swept.
* offcheck — flag OFF. Prove creating an ISE forms NO edges and
* engram_consolidate_permanence is a no-op (byte-identical OFF path).
