vh 7b0580dcbe 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.
