+      # VOICE ✅ +0.177 delta_cb at 3.2x the pairwise floor — the BEST arm of five, on both the
+      # primary read and the pre-registered punctuation-stripped secondary (+0.128 at 2.8x), so
+      # ~3/4 of the gain is words rather than marks. Closed 60.8% of the reachable span.
+      # ⚠ This corpus's voice axis is DELIBERATELY harder than Brontë's or Hemingway's: the
+      # `mccarthy` register names its own punctuation tics and the eval drives the base control
+      # with the same prompt, so the adapter earns no delta for "emit no quotation marks".
+      #
+      # NOT COPIED ✅ THE CLEANEST SAFETY RESULT IN THIS LINE. 0.12 hit-rate against HELD-OUT
+      # McCARTHY'S OWN 0.12 — indistinguishable from the author — and its longest verbatim run
+      # (10 words) is SHORTER than the one genuinely unseen McCarthy shares with the train split
+      # by coincidence (12). All 31 matched runs were READ: stock grammar in the commonest words
+      # ("looked at the wolf and he looked at the boy"), and the name-shaped hits are the RENAMED
+      # invented names. Nothing protectable. McCarthy is in copyright with a LIVING ESTATE.
+      # ⚠ The base-unadapted control is defective and its 0.00 is unearned — base writes summary
+      # and cannot collide with a register it does not imitate. Against base this reads as a 12x
+      # red flag; against the author it is 1.0x. Use the author, not base.
+      #
+      # ⚠⚠ THE COST, AND THE GATE'S RULE IS BLIND TO IT. Axis C is ran-on only (ratified
+      # 2026-09-15 because the carrier maxes the other terms) and this adapter passes it with 40%
+      # headroom — but IN-BAND IS 0.65 AGAINST BASE'S 0.89 and on-beat 0.42 against 0.71.
+      # **35% of its generations miss the requested 90-140 word band, against base's 11%.**
+      # Base is GOOD at length here, so the adapter measurably makes direction-following worse.
+      # ⚠ No checkpoint choice fixes this — every adapted arm is 33-48% out-of-band and ran-on is
+      # non-monotonic in epoch (0.38 -> 0.13 -> 0.20 -> 0.28); ckpt300 is the measured minimum.
+      # The fix, if the cost bites, is a retrain targeting length, not a different checkpoint.
+      # IF A CALLER DEPENDS ON A WORD BUDGET, EXPECT ONE GENERATION IN THREE TO MISS IT.
