nx_crispr.nx

nx_crispr.nx -- adaptive signature memory (Tier-1 immune). Biology: CRISPR-Cas is the bacterial adaptive immune system. When a virus infects, bacteria capture a fragment of viral DNA as a "spacer" in their CRISPR array; on next encounter, Cas enzymes match the spacer and cleave the virus. Substrate equivalent: when nx_pamp detects a hit, nx_crispr remembers its content-addressed signature; on next encounter the lookup is O(1) and the response can fire WITHOUT re-running pamp's expensive scanners. THIS COMPLETES THE LEARN-FROM-EXPERIENCE LOOP. nx_pamp is the pattern recognition; nx_crispr is the memory. Together they implement adaptive innate immunity. Per [[feedback-unified-immune- architecture-three-tier]] the signature DB grows across encounters and (V2) shares via peer mesh so every Nishi cell benefits from every Nishi cell's incident history. Composes: nx_pamp -- supplier of new signatures to remember nx_xenocell -- the source of confirmed-hostile events nx_decoy -- decoy hits become CRISPR entries since they prove someone read the decoy nx_evict_journal -- pre-existing forensic substrate; CRISPR complements (pamp_journal is event log, crispr is THE SIGNATURE INDEX) V1 ships a fixed-capacity ring of spacer entries. V2 makes it peer-sharable (content-addressed merkle tree) so the community shares intrusion intelligence without leaking specifics. Gap list (V1 honest perf verdict): - linear-scan lookup; V2 builds hash index for O(1) - no automatic expiration of stale spacers - no peer-mesh federation - no signature-class grouping (every spacer treated independently) genealogy_id: cardinal_2026-05-19_tier_1_innate_immune_microbial + biology_CRISPR_Cas_adaptive_immunity lineage_id: substrate_crispr_v1
