+# Phase 4AI — conditional PN recruitment and APL source audit
+
+Status: `PASS-CONDITIONAL-PN-APL-SOURCE-AUDIT`.
+
+80 existing records; PN events/counts/final states exact; eight fixture histories exact; twelve repeats exact. No new brain experiment, tuning, training, GPU, or learning candidate.
+
+See audit/final-status.json and audit/PN-odor-structure.json. Accepted edges are timed antecedents, not unique causes. Graded-APL cumulative source shares are descriptive, not causal or error-bounded majority claims. Prior CAL failure remains unchanged. Frozen integrity passed; five reference simulations were not rerun.
