BabyYarros: stage the 4B-Base comparison arm, both concurrent and chained
One arm is not a comparison. On the Brontë corpus Base won held-out loss (2.814 against the instruct arm's 2.908) while instruct won instruction-following, and that trade is the open question for Skaldsong. It has to be re-measured on this corpus rather than carried over: BabyYarros is 12% larger and contemporary. Two entry points because the right one depends on a measurement rather than an argument. The box has 98 GiB free against an 18.4 GiB training footprint, so VRAM is not the constraint -- but VRAM was never the binding constraint on a GB10 that onboarding measured at 6x slower than ana-ml2 where compute predicts 2.7x, and where batching was not a throughput lever. If the box is already at its bandwidth roofline, a second job splits the same bandwidth and buys nothing. So: launch-yarros-4b-base.sh takes an explicit --allow-shared-gpu that bypasses the GPU-clear guard, and chain-yarros-4b-base.sh waits on the instruct run and refuses if it produced no adapter. The bypass is an argument and never a default, because the guard's normal job -- stopping a chain from firing into a live run -- is what keeps one lost run from becoming two. A shared-GPU launch stamps its own log with a warning that its s/it is not comparable to a solo run, since the harness is part of the number. Both carry the same gate guard as the instruct arm: refuse to start unless the leak gate report on disk says PASSED. |

BabyYarros: the leak gate passes, and it found three defects nobody was looking for
The gate is new. There was no committed instrument for "does any of the author's own proper nouns survive the rename" -- the Brontë number was produced by hand -- so leak_gate.py is now that instrument, and it runs both directions every time: the same scan over the unrenamed source as a positive control, and a nonce string as a negative one. A detector that only ever sees renamed text cannot distinguish absent from blind. Run against BabyYarros as built it reported 212 surviving entities, not the 86 recorded earlier, because it scans the whole corpus rather than each work separately and it counts the sub-threshold entities rename never looked at. Three findings came out of closing that. The corpus had a typography defect of its own. The D1 notes correctly say no unwrap was needed; a different defect was there instead. The Empyrean books set their chapter epigraphs in small caps and the extractor rendered the run as uppercase while leaving the large initial as a separate token, so the corpus carried "M AJOR A FENDRA'S G UIDE TO THE R IDERS Q UADRANT" -- 106 lines, ~700 splits -- plus 52 drop caps like "T he flight field". That is where the entities called IDERS, UADRANT, NAUTHORIZED and seventeen bare single letters came from. A split initial next to an uppercased run is enough to recover the original mixed case, so the restore is exact rather than approximate: a word with a split initial was capitalised, an all-caps word without one was lowercase. Back matter was inside the prose. The builder splits on chapter headings and nothing follows the last one, so every work carried its acknowledgments, newsletter pitches and cover-artist credits -- 4,555 words naming the author's agent, editors and children, in a corpus whose entire purpose is that no identifiable name survives. And the gate passed at 0 of 314 while Afendra was still in every copy. The name never appears unpossessed, so it keyed as an apostrophe form, and rename and the gate both skip those as contractions -- unrenamed and unreported at once, which is the worst failure shape available. Baxter escaped a different way: wilder renders an in-book news article entirely in lowercase, putting the cap/lowercase ratio at 0.13 against a 0.05 bar. Then a second class the unigram scan structurally cannot see. Riders Quadrant, Flame Section, War Games and Fourth Wing -- the book's own title -- are built from ordinary words the detector correctly refuses to call names. The gate now audits recurring capitalised 2-3grams against an explicit allow list, and rename applies a phrase map after the entity pass. Every new detector flag is opt-in and off by default, and the Brontë entity map was re-derived after each change and confirmed identical in keys, surfaces and every field. The stoplist was built by reading each surface in context, which is why it is short: Violence is Xaden's nickname for Violet, and Continent, Presentation, Barrens, Originals, Montserrat, Athena, Aura, Curator and Sage are all in-world. A plausible-looking guess would have excluded most of them. Final: 0 of 325 entities and 0 of 91 audited phrases survive in any of 30 copy files, both controls passing. The sensitivity floor is stated in the gate's own output -- 3 occurrences for a name, 5 for a phrase -- because a negative without one is unfalsifiable. |

BabyYarros: corpus built, gender resolution fixed, rename blocked on leak gate
Located the source: five Rebecca Yarros works in the Kvasir licensed library, with rights recorded as gated. Built D1 at 208 chapters and 780,744 words, which is 15% larger than the Brontë corpus. No unwrap step was needed because Kvasir's cleaner already emits flowing paragraphs, so the hard-wrap defect that cost a re-cut on Brontë does not exist here. The alphabet was re-derived rather than inherited: 23 non-ASCII letters across three forms, against F02's 4 on a smaller sample. Same ASCII-fold conclusion from a different measurement, which is the reason to re-derive per corpus. The interesting finding is a new pathology. In a rotating first-person POV corpus, every book's narrator gets the wrong gender. Measured against six names verified in the text, the pronoun resolver called Violet male, Leah male and Landon female -- three of eighteen wrong, and all three are the narrator of the book where they were misgendered. A narrator is "I" in her own book, so her name appears mostly inside the other lead's dialogue surrounded by his pronouns. This is Brontë's "Jane called male" amplified by rotating POV. Title-first resolution, which fixed it for Brontë, is nearly blind here because contemporary romance uses given names rather than honorifics. What works is the POV header: resolve each name from the chapters it does not narrate. Validated at 9 correct, 9 held, 0 wrong against the previous 7, 8 and 3 wrong, and the instrument refuses to write unless it beats what it replaces. Re-pointing rename.py surfaced three bugs, two of which would have silently corrupted the corpus. Gender came only from honorifics and the entities file's gender field was ignored, so the POV fix had no effect until wired through; that took wilder from 1 gendered entity to 13. The pool labels were hardcoded in a print statement, so any non-Brontë preset crashed. And the collision-filter log claimed it dropped names colliding with Brontë entities regardless of which corpus it filtered against -- the logic was right but the message named the wrong corpus, which is how a reader later concludes the filter ran on the wrong thing. D3 is blocked and nothing has been trained. The leak gate shows 86 of 232 renameable source entities surviving where the Brontë run reached 0 of 203. It decomposes into detector false positives that need a stopword filter rather than renaming, genuine misses among worldbuilding proper nouns, and a third class whose cause is not yet established. Training before the gate passes means fitting in-copyright text with 86 identifiable source entities intact, in a corpus F02 already flagged as small enough for leak to be a real concern. |
