nx_abortive.nx -- compromised-cell self-termination state machine (Tier-1 immune). Biology: bacterial abortive-infection (Abi) systems are altruistic suicide mechanisms. When a phage infects a bacterium that has an Abi system, the cell kills itself BEFORE the phage can replicate + spread to neighbors. The colony survives because the infected cell took the phage down with it. In multicellular organisms, the analogous mechanism is apoptosis -- programmed cell death of compromised, mutated, or virally-infected cells, recycled cleanly by macrophages without inflammation. Substrate equivalent: a cell that detects internal compromise (failed self-attestation, ransomware-pattern via nx_immune, sustained PAMP hits, BMS-firmware-out-of-spec, etc.) terminates itself BEFORE it can spread the compromise to peers via nx_hypha EXCHANGE_*. The germline data persists per soma/germline doctrine; the cell can be regenerated cleanly via nx_regenerate from sovereign source. Per META-CARDINAL feedback-unified-immune-architecture-three-tier: nx_abortive is the safe-shutdown primitive in the cell layer; nx_lysis is the substrate's external selective-neutralization toolkit; nx_prune is the operator-confirmed quarantine of contaminated soma. All three compose; nx_abortive is the cell's own self-honest mechanism. State machine (sealed): HEALTHY -- no compromise indicators FLAGGED -- one+ indicator surfaced, awaiting corroboration QUARANTINED -- cell stopped accepting new work; existing work drains TERMINATING -- shutdown sequence active TERMINATED -- cell stopped; germline preserved Transitions: HEALTHY -> FLAGGED (one indicator) HEALTHY -> QUARANTINED (two+ corroborated indicators) FLAGGED -> QUARANTINED (corroboration) FLAGGED -> HEALTHY (false positive cleared) QUARANTINED -> TERMINATING (drain complete OR explicit abort) TERMINATING -> TERMINATED (germline preserved + cell stopped)
