nx_observatory.nx

nx_observatory.nx -- external watcher for paired-cell dyads. Astronomical observatories watch celestial bodies from a distance without touching them. Nishi observatory watches nx_dyad pairs (or organism-level cell sets) from outside the cells' isolation boundaries -- it READS what cells emit but never writes into them. Per [[feedback-cell-immune-system-ransomware-judo-ddos-by-bit]]: "verify D observer received parallel telemetry without vacuole bytes crossing." Observatory is the substrate primitive for that "parallel telemetry without crossing." Sees both A's and B's outputs side by side; computes a comparison metric; surfaces divergence + agreement counts. Naming: nx_observer is too generic (Observer pattern in nearly every framework). nx_observatory keeps biology/science-domain distance and matches the "external scientific instrument" semantic exactly. Composes: nx_dyad -- the paired cells being watched nx_provenance_chain -- observatory's reading is a transform; chain-logged nx_evict_journal -- significant divergence events logged nx_xenocell -- when one cell of the dyad turns hostile, the observatory catches the deviation before it spreads V1 ships: - struct NxObservatory with dyad pointer + sample ring + agreement_count / divergence_count - sample(): grab one reading of A and B's outputs, compute diff bytes, increment agree-or-diverge counter - agreement_q10(): Q10 ratio of agreements to total samples - is_divergent(): predicate firing when divergence_count exceeds caller-supplied threshold Gap list (V1 honest perf verdict): - byte-equality diff is coarse (V2 supports semantic-diff callbacks for structured outputs)
