+E03 (`run-c18babdb7be34396a07fbb994c23d4cb`) changed only regularization from
+0.00 to 0.10. The saved 53.8 GB BF16 checkpoint was independently reloaded for
+each evaluation after verifying all 35 checkpoint inventory entries by size and
+SHA-256. With the corrected full-completion coherence scorer, the immutable
+optimizer-tune split produced 1.41% refusal (2/142), 100% coherence, 83.3%
+capability, 3.21 perplexity (1.02x pristine), and 1/142 degenerate harmful
+responses. It therefore earned exactly one evaluation on the untouched final
+split. That final saved-checkpoint reload produced 1.0% refusal (2/200), 100%
+coherence, 83.3% capability, 3.21 perplexity, and 6/200 degenerate harmful
+responses. Both durable evaluation records are hashed in the run manifest.
+
+E03 passes the declared promotion gates of refusal below 30% and coherence of
+at least 80%. The 3% final harmful-output degeneracy rate remains a follow-up
+quality concern and should be included in downstream human and classifier
+audits rather than hidden by the aggregate promotion result.
