voices-seat: ship lv-bronte (ckpt475) with its failed voice axis on the record

Browse Source 
lv-bronte is live on vllm-voices (fv-ml1 GPU0 :8027) alongside voices-base and
lv-yarros. The seat lists all three; container healthy; GPU0 96092 -> 96090 MiB,
so the adapter cost nothing measurable.

IT DID NOT PASS ITS VOICE GATE, and the artifact says so in three places — this
commit, a comment in the compose file, and a README beside the adapter on NFS —
because an adapter found without its provenance will otherwise be read as a pass.

  VOICE       FAIL  +0.193 delta_cb vs base, against a 0.251 measured noise floor
  NOT COPIED  PASS  8-gram hit-rate 0.00, longest 0 - identical to the control
  NO DAMAGE   PASS  ran-on +0.15 against a 0.400 floor

Shipped on three grounds, none of them that the number was nearly good enough:
it is additive (a named LoRA nobody reaches without asking for it), reversible
(one compose line; hot-unload measures 0.003 s), and clean on the axis that
carries actual risk - verbatim regurgitation of the source, on a public-domain
corpus, measured against a positive control that saturates at 160.

The voice result is UNDERPOWERED rather than absent: it closed 48% of the span
from base to the same-author target and beat the control on every individual
seed. The cause is structural - 81 val pairs against Hemingway's 200, from a
678k-word corpus against 994k - and neither more beats nor more seeds fixes it,
because the floor is a range statistic and ranges widen with n.

ckpt475 over ckpt925: indistinguishable on voice (0.017 apart), but ckpt925 has a
verbatim 8-gram hit where this has none, and is 2.7x less stable seed-to-seed
(0.251 vs 0.092) with a degeneracy probe showing no collapse to explain it.

# `[2026-09-17]` lv-bronte: corpus gated for real, adapter trained, v2 gate FAILS the voice axis — ship call is the operator's
# `[2026-09-17]` lv-bronte: corpus gated for real, adapter trained, SHIPPED with a FAILED voice axis on the record
**Status: trained and gated, NOT shipped.** The decision is open and belongs to the operator.
**Status: SHIPPED 2026-09-17 01:24 as `lv-bronte` on `vllm-voices` (fv-ml1 GPU0 :8027), ckpt475 —
and it did NOT pass its voice gate.** Shipped because it is additive (one more named LoRA beside
`voices-base` and `lv-yarros`, reached only by requesting it), reversible (one compose line; hot-unload
measures 0.003 s), and clean on the SAFETY axis — 8-gram overlap identical to the never-saw-it control,
on a public-domain corpus. VRAM cost was nil: GPU0 96092 -> 96090 MiB. The caveat is written into the
compose file and into `/tank/aimodels/voice-adapters/lv-bronte-4b-v1/README.md` so it cannot be read
as a clean pass by anyone who finds the adapter without finding this note.
⚠ **Do NOT cite lv-bronte as evidence pair-SFT works for this author.** The voice axis is unresolved,
not passed.
