voices-seat: ship lv-hemingway (ckpt850), and replace the memorisation control that passed it

Browse Source 
Live on vllm-voices (fv-ml1 GPU0 :8027) beside voices-base, lv-yarros and lv-bronte.
Healthy 190 s after recreate, four models served, GPU0 96,092 -> 96,090 MiB. The adapter
was verified byte-identical to checkpoint-850 by sha256 across both transfer hops, and the
seat was verified by generating, not by reading its config: base emits 170 words of <think>
planning and never writes the passage, lv-hemingway writes the scene.

Gate design was pre-registered before any generation existed (0bb4938). Three arms, 60
held-out beats, 4 seeds, 240 generations per arm.

  A. VOICE   PASS 6.4x   +0.413 delta_cb, pairwise floor 0.064 -- and it clears the OLD
                         all-arms floor (0.113) too, so this verdict does not lean on the
                         rule change. Closes 73.8% of the span between the unadapted
                         carrier and held-out Hemingway itself; lv-bronte closed 48%.
  B. NOT COPIED  see below
  C. NO DAMAGE   PASS    ran-on +0.08, on-beat -0.14, both inside a 0.217 floor

AXIS B: THE NEGATIVE CONTROL WAS THE WRONG ONE, AND FIXING IT MADE THE RESULT WORSE, NOT
BETTER. memorization_check.py uses the base-unadapted arm as its control. Base writes
18,035 words of summary against the adapted arms' 27,413 of pastiche, and text that does
not imitate a register cannot collide with its n-grams -- so base's 0.00 measures "different
register", not "did not memorise". The comfortable reading was that Hemingway's plain
high-frequency prose makes collisions inevitable for any arm that learns it. That is
refutable, so it was tested: held-out Hemingway, the author himself, scored against the
train split at the generations' own median length.

  HELD-OUT HEMINGWAY (never trained)   370 chunks   0.01 hit-rate   mean-longest 0.1   max 10
  base-unadapted                       240 gens     0.00                        0.0        0
  ckpt850 (shipped)                    240 gens     0.07                        0.6        9
  positive control (train vs train)                                             160

The hypothesis is false: the adapter reproduces train n-grams ~7x more often than the
author reproduces himself. That is real and is on the record. All 19 matched runs were then
READ rather than counted -- every one is stock dialogue ("came over and sat down at the
table", "how do you feel i feel very well"), capped at 9 words, with no plot, no imagery and
no proper noun; the one name-shaped hit is the RENAMED invented name. Nine is shorter than
the 10-word run unseen Hemingway shares with the train split by coincidence. Elevated rate,
zero protectable content. Hemingway is in copyright; lv-yarros is the in-line precedent,
also in copyright, shipped at 0.10 against a 0.07 control. Unload is 0.003 s.

The durable lesson is about the instrument: a negative control that differs from the
candidate in a way correlated with the metric is not a control. memorization_selfsim.py and
memorization_dump_matches.py are committed so the claim can be re-derived rather than taken
on faith.

SHIPPED ckpt850, NOT the loss minimum at step 1750. The two are indistinguishable on voice
-- 0.072 apart against a 0.113 pairwise floor -- so the pre-registered tiebreak fell to the
axes that resolve, and 850 wins all of them: 2.3x tighter seed spread (0.050 vs 0.113),
lower memorisation, less ran-on, half an epoch less overfit. ckpt1750's spread is one seed
(0.491, 0.449, 0.468, then 0.562), the same lone-outlier shape that lost ckpt925 the
lv-bronte tiebreak. The two-epoch recipe is now 0 for 2 and should stop being carried
forward; only the epoch-3 collapse is robust at 17.4x jitter.

servers/fv-ml1/ssh-target was a bare IP, so deploy-stack.sh connected as lkraven, could not
write the infra-ops-owned /opt/docker/compose, and could not escalate either because
lkraven's sudo on fv-ml1 wants a password. Now infra-ops@10.251.50.54; --validate-only stays
clean and the deploy works through the repo's own tool rather than around it. Other hosts
may carry the same gap -- a read-only refresh works as either user, so it only surfaces on a
deploy.

### Next goal: land `lv-hemingway`. It is TRAINED; nothing else has been done to it.
### SHIPPED — `lv-hemingway` on ckpt850, the line's first clean voice pass
**Ship candidate is `gx10:~/r49-runs/hemingway-4b-pairs-3ep/checkpoints/checkpoint-1750`**
(epoch 1.97, eval_loss 2.2783 — the loss minimum). The run finished 2026-09-16 18:27, 2,661
steps in 3:17:34, clean. The end-of-run `adapter/` is **0.0763 worse** (2.3546) — epoch 3
overfits and plateaus. Do NOT ship `adapter/`; the run's own log says so.
Live on `vllm-voices` (fv-ml1 GPU 0 :8027) beside `voices-base`, `lv-yarros`, `lv-bronte`.
**VOICE +0.413 delta_cb at 6.4x its floor** — closes 73.8% of the achievable span, and clears
the OLD all-arms floor too, so the verdict does not lean on the rule change. **DAMAGE clean.**
⚠ **MEMORISATION is the axis to read**: 0.07 hit-rate against **held-out Hemingway's own
0.01** — ~7x the author's self-collision rate — but all 19 matched runs were read and every
one is stock dialogue capped at **9 words**, no proper noun, no plot. Elevated rate, zero
protectable content; in-copyright author, so the fair-use call is the operator's.
→ `persistent-memory.d/2026-09-17-lv-hemingway-gate.md`
**The v2 gate has NOT been run on it.** Everything it needs now exists and is parameterised,
built during the lv-bronte run tonight — reuse it rather than rebuilding:
⚠ **ckpt850, NOT the loss minimum at 1750** — the two are indistinguishable on voice (0.072
gap vs a 0.113 floor) so the tiebreak fell to the resolving axes, and 850 wins all of them
(2.3x tighter spread, lower memorisation, less ran-on, half an epoch less overfit).
**The two-epoch recipe is now 0 for 2.** Read the curve; prefer the earlier tied checkpoint.
1. `scripts/r49-corpus/build_beat_fixture.py --pairs <hemingway val pairs> --out beats-hemingway-30.json --sidecar ... -n 30` — refuses any split but `val`.
2. `scripts/r49-corpus/gen_beats_chat_yarros.py --system-from <pairs>.provenance.json` — **the `--system-from` flag is mandatory**; the harness's hardcoded SYS is Yarros's and driving a Hemingway arm with it confounds the carrier change with a prompt change.
3. `scripts/yarros-corpus/memorization_check.py --eval-dir ... --corpus ... --glob 'beats5.*.jsonl'` — **now takes paths**; its old hardcoded Yarros defaults would have compared a Hemingway arm against the Yarros corpus and reported a meaningless clean zero.
4. `scripts/r49-corpus/voice_distance.py <renamed-corpus> <eval-dir>` — needs `voice.<arm>.jsonl` files with a `continuation` field, and identifies the control by the substring **`unadapted`** in the arm name. Adapt with a script like `gx10:~/lv-bronte/voice-prep.py`.
### OPEN for the operator — two measured defects, neither acted on
⚠ **Hemingway's pairs were built BEFORE the `--source-entities` beat filter existed.** Measured
on Brontë: 1.8% of generated beats named the author's real characters, because the beat-writing
model recognises the book and restores canonical names — a leak the corpus gate structurally
cannot see. Exposure scales with how famous the book is. **Re-verify the Hemingway pairs against
its entity map before trusting them**, and regenerate with `--source-entities` if they leak.
1. **Hemingway's TRAIN beats carry the source-name leak: 70 of 7,094 (0.96%)** (Santiago x16,
Catherine x7, Rinaldi x3 ...), responses 0 of 7,294, **val 0 of 200 so the gate itself is
unconfounded**. `audit_pairs_sourcenames.py --filter-out` yields a verified-clean
7,024-pair set in one command. **Retrain ~3h17 + re-gate ~1h40, unattended.**
2. **130 of 946 entity-map surfaces are probably not names** and were renamed anyway
(`African`, `Chinese`, `X-ray`, `Coca-Cola`, `Ritz`, `Prado`), plus **16 bare initials
incl. `C` at 274 occurrences** — 1,616 instances, 0.162% of corpus words.
`audit_entity_map.py` finds them; they need READING, not auto-removal, because
`the Widow` / `the Informer` are genuine epithet-names that should be renamed.
⚠ **Do not assume the two-epoch recipe.** It held for Yarros and Hemingway and did NOT hold for
Brontë. Read the eval curve; Hemingway's minimum genuinely is at 1750, which is already known.
### SHIPPED tonight — `lv-bronte`, with a FAILED voice axis on the record
Live on `vllm-voices` (fv-ml1 GPU 0 :8027) as `lv-bronte` beside `voices-base` and `lv-yarros`.
Checkpoint-475. **It did not pass its voice gate** (+0.193 delta_cb against a 0.251 measured
floor); shipped because it is additive, reversible, and clean on the safety axis (8-gram overlap
0.00, identical to the never-saw-it control) on a public-domain corpus. The caveat is written
into the commit, the compose file, and a README beside the adapter on NFS.
→ `persistent-memory.d/2026-09-17-lv-bronte-gate.md`
Both would be fixed in one pass if a corpus rebuild happens. Neither blocks anything today.

- `[2026-09-17]` ⭐⭐⭐ **lv-hemingway SHIPPED (ckpt850) with the line's strongest voice result — and the memorisation control it passed turned out to be the WRONG control.** Voice +0.413 delta_cb at 6.4x the floor, closing 73.8% of the achievable span (lv-bronte closed 48%). ⚠ `memorization_check.py` uses the base-unadapted arm as its negative control, but base writes 18,035 words of summary against the adapted arms' 27,413 of pastiche — **text that does not imitate the register cannot collide with its n-grams**, so a 0.00 there means "different register", not "did not memorise". The right reference is the author himself: **held-out Hemingway against the train split collides at 0.01 while the adapter does at 0.07**, so the comfortable "his plain register makes collisions inevitable" story is FALSE and was refuted rather than assumed. All 19 matched runs were READ: stock dialogue, max **9 words**, no proper noun — shorter than the 10-word run unseen Hemingway shares with the train split by coincidence. ⭐ **A negative control that differs from the candidate in a way correlated with the metric is not a control.** → `persistent-memory.d/2026-09-17-lv-hemingway-gate.md`
- `[2026-09-17]` ⭐⭐ **The v2 voice floor is now PAIRWISE, and it retroactively passes lv-bronte.** lv-bronte's ckpt475 shipped as a voice-axis FAILURE at +0.193 against a 0.251 floor contributed 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 0.091 and it clears at **2.1x**. The rule was changed **prospectively**, pre-registered for lv-hemingway before any Hemingway number existed, on an argument independent of the answer: the sampling variability of a difference A−B depends on A and B, never on a third arm C. The previous session found the defect and deliberately declined to exploit it; this follows from fixing it. lv-hemingway passes under **both** rules, so its verdict does not lean on the change. Caveats amended append-only in the compose, the NFS README and the gate record. Commits `0bb4938` `2e9b118`.
- `[2026-09-17]` ⭐ **The beat-contamination leak IS present in Hemingway — 70 of 7,094 train beats (0.96%), 0 of 200 val.** `scripts/r49-corpus/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). Cross-validated on real data: the fixed Brontë pairs return 0 of 3,858 and `pairs-full.CONTAMINATED` returns 15 of 792 = 1.89% with the recorded names. `--filter-out` yields a verified-clean 7,024-pair set in one command; the retrain is the operator's call. **The val split being clean is why the gate could run at all.**
- `[2026-09-17]` ⭐ **`audit_entity_map.py` — the rename can DAMAGE the prose and no gate will ever say so.** Mirror of `audit_stoplist.py`: surfaces wrongly held IN the map rather than out of it. 130 of 946 Hemingway surfaces flagged (1,616 instances, 0.162% of words) — `African`, `Chinese`, `X-ray`, `Coca-Cola`, `Ritz`, `Prado` renamed into invented names — plus 16 bare initials incl. `C` at 274 occurrences. Signal is a preceding article; controls derived from the corpus, not hand-picked. Every hit reported for READING: `the Widow` and `the Informer` are genuine epithet-names that should be renamed. Commit `051b99e`.
- `[2026-09-17]` **The two-epoch recipe is now 0 for 2 and should stop being carried forward.** Hemingway's eval minimum is step 1750, but step 850 is +0.0040 against a 0.0044 median neighbour jitter — three checkpoints inside one jitter — and 850 won every resolving axis (2.3x tighter seed spread, lower memorisation, less ran-on). Same outcome as Brontë. What IS robust on this schedule is the epoch-3 collapse: +0.0762 = **17.4x jitter**.
- `[2026-09-17]` **gitea was reaching the PUBLIC route from every repo on nh3-dev** — brokkr-smithy, sleipnir, Galdrabok, kvasir — and brokkr-smithy is pushed several times a week, so the fail2ban trigger was live, not dormant. Measured before acting (no split-horizon rewrite, no ssh alias, `ssh -G` confirmed port 22 to 38.120.12.44). Fixed by overriding the NAME once in `~/.ssh/config` rather than rewriting N remotes, so fresh clones and unaudited repos are covered too. Verified with a real `git ls-remote`, not by inspection. Commit `dcc1abc`. Flagged by brokkr-smithy-dev; `vh/imogen` created for them the same session.
- `[2026-09-17]` **`servers/fv-ml1/ssh-target` was bare `10.251.50.54`, so `deploy-stack.sh` connected as `lkraven` and could not write the infra-ops-owned `/opt/docker/compose/`** — and lkraven's sudo on fv-ml1 needs a password, so `DEPLOY_SUDO=1` failed too. Now `infra-ops@10.251.50.54`; `--validate-only` still clean, deploy works. ⚠ Other hosts' `ssh-target` files may carry the same gap — a read-only refresh works as either user, so the fault only surfaces on a deploy.
- `[2026-09-17]` ⭐⭐ **A leak class the corpus gate structurally CANNOT see: the beat-writing model recognises the book and restores the author's real character names.** 1.8% of Brontë beats named Rochester/Jane/Brocklehurst while 0 responses did. Worst for public-domain classics; Yarros and Hemingway's clean runs are NOT evidence they are immune. Patched as a `sourcename` reject + `--source-entities`. → `persistent-memory.d/2026-09-17-beat-contamination-leak.md`
- `[2026-09-17]` ⭐ **A stoplist entry is an assertion the leak gate can no longer check** — stoplisting removes a surface from the entity map, so a wrongly stoplisted CHARACTER is an undetectable leak. Three were wrong on Brontë (Leaven, Pierrot, Samuel); `scripts/r49-corpus/audit_stoplist.py` finds them by honorific and now gates the pipeline. Commit `8bb7686`.
- `[2026-09-17]` **ESH: Cityside Fiber failed TWICE (19:09 and ~01:06); operator switched WAN1 to DHCP to restore service and has a ticket for the static.** crowdsec `esh` allowlist carries both failover egresses with 7-day expiries — the rotation-fragility is live. → `persistent-memory.d/2026-09-17-esh-fiber-outages.md`
