nx_homeostasis.nx

nx_homeostasis.nx -- steady-state monitor that triggers migration. Biological analogue: homeostasis is the body's set-point control -- when blood glucose / pH / temperature drift past tolerance bands, counter-regulatory signals fire. Nishi homeostasis watches each cell's budget pressure, eviction history, and metabolism heat; when any drifts past its set-point, it emits a migration signal that nx_tropism resolves into a concrete relocation target. This is the structural EXCEED-axis vs the kernel OOM-killer: the kernel waits until the host is OUT of memory and then kills the biggest offender after the fact. Homeostasis fires PROACTIVELY at 90% pressure (Q10 921), giving the substrate slack to relocate the cell cleanly before any user-visible disruption. Composes: nx_budget -- pressure_q10 per resource nx_evict_journal -- count_for_cell to spot eviction storms nx_metabolism -- hot sites are migration candidates nx_attention_class -- foreground cells prefer local migration; idle cells are offload-OK to peer/cloud nx_tropism -- consumes the migration signal to pick target V1 ships per-cell snapshot polling. Continuous monitoring (an integrator that fires on sustained pressure rather than instantaneous) is queued; today the caller drives polling at its preferred cadence (a 100ms tick is the canonical default). Gap list (V1 honest perf verdict): - no integrator / leaky-bucket dampening (transient spikes can fire migration signals) - no cross-cell pressure (only per-cell, not host-aggregate) - no de-bounce on repeated MIGRATE signals from same cell - no return-to-set-point hysteresis (cell re-evaluated each tick) genealogy_id: nishi_cardinal_2026-05-17_cooperative_resource_arbitration + cardinal-21 lineage_id: substrate_homeostasis_v1 nx_safety_envelope: intended_use: "Proactive migration trigger before host OOM;
