`leak_gate.py` scans `\b(Surface)\b`. Any character inserted inside a name defeats
that pattern outright, so a mangled occurrence is unrenameable by rename.py AND
unreportable by the gate. lv-mccarthy's 2026-09-17 tree passed at "0 of 75
renameable and 0 of 37 sub-threshold" while carrying 13 occurrences of Bell,
Chigurh, Moss, Toadvine and Glanton in all six copies:
B ell C higurh M oss T oadvine a small-caps drop cap kept as its own token
Toad-vine Glan-ton a print line-break hyphen kept by the extractor
Every visible occurrence HAD been renamed, which is what made the residue invisible
to a spot-read. Fixed at three levels, all three of which must stay:
build_corpus_mccarthy.py rules 4 and 5 repair the source text — 32 split initials
with a lowercase remainder, 5 hyphen-split names, each with an expected count so a
master change fails the build. Rule 4's letter class is consonants only: `I` opens
1,966 paragraphs, `A` 143 and `Y` 32 (Spanish `y`); folding any would corrupt 2,141
lines to fix 32.
leak_gate.py gains a separator-tolerant pass with its own positive and negative
controls, and it FAILS the gate. Validated against the pre-fix tree: reports all
five surfaces, exits 1. Its fragment filter is what makes it usable — a naive scan
returns 18 false positives on Hemingway (`God damn`, `I run`) against 3 real ones;
requiring one fragment to be a non-word of the corpus cleared all 18 and kept all 3.
The whole D1→D3 chain is reproduced byte-identically before and after, so the fix
is the only delta: 6 works, the entity map, the final map and all 36 copy files.
Cross-checked on the shipped corpora: lv-bronte is clean of this class, lv-hemingway
carries 3 (`Primi tivo`, `Pasionar ia`, `Chi cote`) and is live on fv-ml1.
Also in build_sft_pairs.py, both needed before lv-mccarthy's pairs:
DEFECT 4, hard-wrap reflow. Measured on the SHIPPED lv-bronte adapter, which emits
mid-sentence line breaks at 12.46 per 1k chars against 0.00 for its own base control
and 0.00 for every Hemingway arm. McCarthy is the mixed case — The Road is wrapped,
the other five works are not — so the corpus teaches the break as a coin flip. The
obvious fix (join every interior newline) corrupts 46 two-speaker exchanges whose
blank line was lost, and unmarked dialogue is the one thing this adapter exists to
learn; the rule splits on sentence-final punctuation instead and takes the cheaper
error. Self-targeting and off by default, so every shipped pair set is unchanged.
A `mccarthy` register, which names the punctuation deliberately: the eval drives the
base control arm with this same prompt, so tics left out of it are a surface trick
only the adapter can perform, and delta_cb is a character-bigram measure.
drop_leading_heading now also consumes Blood Meridian's dash-separated chapter
arguments — 131 paragraphs, 0 in every other work of all three corpora.
And a RUNBOOK, because the D1→D3 session recorded nothing and the chain had to be
recovered by rebuilding candidates and matching sha256 against the artifacts on disk.
