The gate design is written before any generation exists, because lv-bronte's
verdict turned on a choice that was only visible after the numbers printed.
THE FLOOR RULE IS NOW PAIRWISE. lv-bronte computed the noise floor as the largest
within-arm seed spread across ALL arms present. Its ckpt475 shipped at +0.193
against a 0.251 floor set entirely by ckpt925 -- a third arm nobody was shipping,
on one outlier seed. Scored against the arm it was actually compared to, the floor
is 0.092 and the same gap clears at 2.1x. A candidate's verdict must not depend on
which other arms happened to be generated. voice_distance.py now prints both floors
and flags any disagreement, so the lv-bronte record stays comparable.
audit_pairs_sourcenames.py closes the blind spot leak_gate.py has by construction:
it reads the corpus and the renamed copies, never the generated beats, so it cannot
see a beat-writing model restoring the author's real character names. Run over the
Hemingway pairs, which predate build_sft_pairs.py --source-entities:
val 0 of 200 -- the eval fixture is clean, the gate is unconfounded
train 70 of 7,094 (0.96%) -- Santiago x16, Catherine x7, Rinaldi x3, Brett,
Harry, Jake, Pablo, Nick, Maria ...
responses 0 of 7,294 -- the lv-bronte beat-only signature exactly
A matched surface is only counted when the rename actually removed it, verified
against the renamed copies, so a beat naming a held real-world place is not a leak.
Controls run every time: 941/941 surfaces found in the unrenamed source, nonce
absent from both trees, and 6 planted canonical names detected 6/6.
voice_distance.py --author is now REQUIRED. It was hardcoded "Yarros" and printed
"reference: held-out Yarros" over Brontë's numbers into a committed artifact. A
default would have moved the silent-wrong-label failure rather than removed it. The
stale "one seed-pair per arm / corroborates Base < Instruct" footer is replaced with
what the run actually carries.
Gate design: three arms (base-unadapted, ckpt1750, ckpt850), 60 beats, 4 seeds.
ckpt850 is present because the loss curve cannot separate it from ckpt1750 -- +0.0040
against a 0.0044 median neighbour jitter, with three checkpoints inside one jitter of
the minimum. adapter/ is excluded: +0.0762 is 17.4x the jitter and is resolved without
a gate.
Adds the Yarros-side evaluation the training exists to justify: does the adapter
move arbitrary prose toward Yarros, and can the instruct arm still expand a beat
to a paragraph on direction. Yarros-flavoured voice prompts (modern/neutral/
romantasy tiers so any Yarros voice in the modern tier is adapter-attributable,
not prompt-supplied) and a Yarros-register beat SYS on the chat generator.
voice_distance.py is the honest slice of adjudication that needs no seat: Burrows's
Delta over character bigrams against held-out Yarros. Its first cut mis-framed the
noise floor — it used the same-author distance (held-out vs itself) as the
between-arm significance threshold, which is the target, not the threshold. Fixed
to the measured floor: the within-arm seed spread, which is this metric's sampling
variance at this sample size, computed from the two seeds already generated rather
than assumed.
Result on the built corpus, ordering base-125-tuned < instruct-tuned <
base-unadapted, both adapters clearing the 0.046 measured floor (base +0.157,
instruct +0.076), and the ordering corroborating the independent held-out loss
ordering (Base below Instruct). One seed-pair per arm, so it corroborates rather
than settles; the full frozen adjudication still needs a romantasy control panel,
a second seed, and the gen seat for the beat-incumbent leg.
