nh3-pve and esh-pve are the same Minisforum MS-01 (BIOS AHWSA.1.17). With a
card in the x16 slot its root port takes bus 01 and every NIC moves down a
bus (measured on esh-pve), so predictable names change (enp2s0f0np0 ->
enp3s0f0np0 etc.) and vmbr0 would boot with no uplink. systemd .link files
now pin all NICs by MAC, baked into every initramfs and synced to the ESP;
udev confirms the files apply. The AMT-capable I226-LM (enp88s0) leaves
vmbr0's bridge-ports in the file (next boot), so cabling it for AMT cannot
loop the STP-less bridge.
Also: documented the NanoKVM (https://10.100.250.171) as nh3-pve's console
OOB and that AMT is not wired; nh3-dev's Beszel agent no longer binds NAS
shares (it died on the last NH3 cold start); post-boot checklist in
persistent-memory.
- Beszel: NVIDIA agent (stacks/beszel hosts/esh-ml1.yaml), hub system
registered with Status/Disk/CPU/Memory/Temperature alerts; GPU samples
verified (RTX 2000E Ada util, VRAM, power, temp).
- Uptime Kuma: health monitors for the TEI embed (:8001) and rerank (:8013)
services — the sole backends behind the gateway, so the one exception to
"seats are out of Kuma's lane". Reward seat excluded (no consumer).
- Homepage: dockerd on tcp/2375 bound to 10.0.50.80 (playbook step);
esh-ml1-docker added to docker.yaml.
- Dozzle: agent v10.4.1 on esh-ml1. The hub's DOZZLE_REMOTE_AGENT still
named ana-ml2's 10.250.50.54 and irv-ml1's retired 10.100.79.3; repointed
to 10.251.50.54 / 10.6.110.50 (fv-ml1 and irv-ml1 logs were missing).
- Documented nh3-dev's Beszel agent failing on NH3 cold start (bind of an
automounted NAS share); revived by hand, fix still open.
Prime, 2026-09-25: TEI serves embedding + reranking for esh-ml1 and the fleet
from now on; fv-ml1 retires both once esh-ml1 is up.
- stacks/embed-rerank: vLLM -> TEI 1.9.4 (89- Ada build), same ports
8001/8013, fail-closed truncation (--auto-truncate false; embed
--max-batch-tokens 32768).
- litellm: qwen3-embedding -> esh-ml1 only (hosted_vllm/, unchanged address);
reranker -> huggingface/ provider at :8013 (hosted_vllm/ 422s on TEI's
`texts` body). DB alias reranker-a3-bge-v2-m3 patched to the same target.
- Verified via the gateway against the retiring fv-ml1 seats: embed cosine
median 0.999927 (n=203); rerank top-1/top-3 29/30.
- stacks/vllm: vllm-embed and vllm-rerank-a3 removed (containers retired on
fv-ml1, GPU 1 freed ~6.1 GB); reward + coder unchanged.
- Bake-off record moved to docs/pfi/embed-rerank-tei-vs-vllm-bakeoff.md;
CLAUDE.md gains the TEI convention.
esh-pve: NVIDIA 580.178.04 (open modules, DKMS) installed on the host from
NVIDIA's .run and loaded live, no reboot. nvidia-persistenced unit creates the
device nodes before pve-guests; the T400's vfio-pci ids and `blacklist nvidia`
retired. playbooks/esh-pve-nvidia-host.yaml.
esh-ml1: CT 110, unprivileged Debian 12, 10.0.50.80, GPU nodes via devN,
NVIDIA userspace from the same .run (--no-kernel-modules), docker-ce +
nvidia-container-toolkit (no-cgroups). playbooks/esh-ml1-lxc.yaml. Not in the
vzdump job on purpose. DNS esh-ml1.esh.internal.
stacks/embed-rerank: Qwen3-Embedding-0.6B :8001 + bge-reranker-v2-m3 :8013 on
the same vLLM v0.24.0 digest and flags as fv-ml1. Measured parity: embed
cosine FV-vs-ESH median 0.999908 (min 0.999772), inside both self-noise
floors; rerank max |delta| 0.000145 vs floor 0.000181, identical ranking.
litellm: qwen3-embedding and reranker gain an esh-ml1 deployment at order 2
behind fv-ml1 (order 1). Order fallback proven with throwaway groups:
refused primary +0.15 s, host-down primary ~18.7 s per call, dead-only 500.
Also: repaired the DB-only alias reranker-a3-bge-v2-m3, dead since the
fv-ml1 relocation (still named 10.250.50.54); documented the third
unkillable homepage wedge on esh-docker-vm.
In-flight rewritten for 2026-09-22 evening. The operator approved both carried
calls ("decide to do both pending"): the NRestarts flap sampler is to be BUILT
(163bb97) and the restic content-assertion ruling is RATIFIED as-is (ba60fda).
Recorded in Recent decisions with tracking pointers, and their modality flipped
in the handoff from do-not-touch to genuine pending work.
safe-rm: installed on nh3-dev, delegated to infra-hermes, now fleet-wide 6/6
with acceptance met. Wiring ruled to /etc/bash.bashrc above the case-$ guard
rather than /etc/environment -- an rc self-guards, smaller blast radius, covers
bash-over-ssh. ⭐ The guarded acceptance test caught infra-hermes's own silent
wiring failure in flight: a probe that cannot destroy what it tests also cannot
lie about it.
⚠ Recorded twice over because it will otherwise be trusted for the wrong class:
safe-rm is a BLACKLIST. It refuses rm -rf /home and deletes an unset-variable
path without complaint. set -u is the actual cover for the habit that prompted
the install.
D-0010/D-0011: genuine, operator-approved, misrouted to this seat by pane_find
matching a ROLLING PANE TITLE. Belayed both, nothing lost. svos-dev owns the fix
and found the sharper half -- pane_send structurally cannot deliver a harness
command, so D-0010 promised an unachievable /clear and its receipt reported
success anyway. {"sent": true} is a claim about transmission, never effect.
Live thread carried: restic/ana/esh-docker-vm has drifted 36h -> 44h against a
48h threshold while every other repo sits at 12h. Drifting, not static.
In-flight rewritten for 2026-09-22. The Booth is booth-dev's now (extracted to
vh/booth, v0.2.0 shipped by them); infra-ops retains only its Uptime Kuma
monitor.
Eight decisions recorded, and three OPEN OPERATOR DECISIONS filed under Recent
decisions with commit tracking pointers rather than under in-flight, per the
deferred-work rule: the NRestarts flap sampler (163bb97), safe-rm, and
confirming the restic content-assertion ruling that reached me relayed by
svos-dev rather than Miranda (ba60fda).
Detail file for the day's throughline: five instrument errors, one shape -- a
tool that enumerates 'things that are fine' has selected against its own
subject. Four were mine, one a peer's, and mine included making theirs, on the
same day we were both cataloguing the habit. Written down because a rule both
parties broke while discussing the rule needs to live where a fresh session
reads it.
Two loose threads carried: talk.service failed while still serving on :8092,
and restic/ana/esh-docker-vm 36h behind the fleet.
The in-flight section had gone self-contradictory: its header said lv-mccarthy
SHIPPED while the body still carried the pre-ship draft (It is NOT shipped for
one reason...) and an unpushed-commit count that was no longer true. That section
is decay-prone by design and rewrites freely; this is the rewrite.
Now leads with the Booth (services/booth) as the next work, carrying the context a
fresh session needs before its first question -- what the board is, and the warning
that its last two sessions each shipped a control that did nothing, both found by
the operator rather than by me, because I read templates instead of rendering them.
lv-mccarthy is compressed to the ship facts plus its two carried-forward items: the
length defect (open follow-up is a retrain folded into Faulkner's pair build per the
operator's steer, not a checkpoint change) and the Skaldsong think-tag check. Every
number lives in the detail file.
Push state is now recorded as VERIFIED rather than asserted -- rev-list
origin/main..HEAD = 0 -- and the wall-clock stamps are corrected to ~21:05 PT after
the handoff generator's UTC stamp showed the session had run three hours past what
I had written.
NO ARCHIVAL this run despite the index sitting at 514 lines against a ~300 soft cap.
Only 5 of 181 dated entries predate the 14-day guard, and all five carry an open
deferred-work pointer (parked ospool/naspool-evac; run 3c staged and deliberately
not launched; fused-MoE at park 47; nconnect=8 tracked at an althing thread; the
AI-tab regrouping belayed, untracked by operator choice). The guard holds every one,
which is the intended outcome -- an over-cap file that keeps live decisions beats a
scannable one that lost a decision.
SHIPPED 2026-09-21 18:01 PT. lv-mccarthy = checkpoint-300, fourth voice on
voices-seat (fv-ml1 GPU0 :8027). Seat healthy, five models served, GPU0 96,012 MiB
against 96,090 with three adapters -- a LoRA rides inside the existing seat and
costs nothing.
Verified by read-back rather than by the deploy's exit code. Live smoke test:
lv-mccarthy 96 words / 0 quote marks / "wasnt" with no apostrophe; lv-hemingway
135 words, no regression; voices-base 221 words, 12 quote marks and a visible
reasoning preamble -- the adapter is doing real work.
THE PROCESS FAILURE IS RECORDED BECAUSE IT IS THE LESSON. I held the ship three
times and only the first hold was right. Hold 1 was correct: the gate as frozen
failed both candidates. Hold 2 was wrong -- having proven my own axis C
arithmetically unsatisfiable, I invented a STRICTER bar of my own and treated it as
binding over an explicit authorisation. Hold 3 moved the goalposts: when I conceded
the bar was mine, I reached for a second reason rather than executing.
Finding successive reasons not to act on a delegated authorisation is its own
failure mode, and it is harder to see than over-eagerness because every individual
hold looks like caution. The tell was structural: each time one reason was refuted I
produced another for the same conclusion. A concern that survives the refutation of
its own grounds was never the real grounds.
The cost shipped unglossed, in the compose, the adapter README and here: in-band
0.65 against base's 0.89, 35% of generations missing the 90-140 band against base's
11%. No checkpoint fixes it; the open follow-up is a retrain targeting length.
AND A SEAT-WIDE DEFECT THE SMOKE TEST FOUND, LIVE SINCE 2026-09-16: every voice
prefixes an empty think block unless the caller sends chat_template_kwargs
enable_thinking false. It is the Qwen3 chat template, not an adapter property, so
all four voices do it. No gate number is affected -- the harness sets the flag -- but
a caller that omits it gets 17 junk characters at the head of every passage, and any
word-count run over that string counts tags as prose. Skaldsong should be checked.
1,200 generations across five arms. ckpt300 (epoch 0.652) is the best arm in the
run on every axis that resolves:
VOICE +0.177 at 3.2x its pairwise floor (primary), +0.128 at 2.8x with
every punctuation mark stripped. Best point estimate AND best
margin of any arm, spread 0.055/0.038 with no outlier seed.
MEMORISATION 0.12 against real unseen McCarthy's own 0.12 -- identical -- with
a longest match of 10 words against the author's coincidental 12.
All 31 matches read: stock grammar, names are the renamed
inventions, nothing protectable.
DAMAGE ran-on +0.12. Clears the operator's ratified v2 floor of 0.200 by
40%. FAILS AMENDMENT 3's self-imposed 0.100 bar by 0.02.
NOT SHIPPED, and the reason is the bar rather than the adapter. AMENDMENT 3 fixed
ran-on <= 0.100 before either new arm existed, precisely so a marginal number could
not be talked into a ship, and shipping at 0.12 would make that pre-registration
theatre. But the bar's stated rationale was written against ckpt450's pass by 0.01
-- 5% of the threshold -- and ckpt300 clears by 40%. The number excludes a candidate
the reasoning does not. That is an operator call.
ckpt325/350/375 are on disk and one may sit under 0.100. They were deliberately NOT
gated: searching the checkpoint space until something clears is candidate-shopping,
the same family as threshold-shopping approached from the other side.
THREE CLAIMS FROM EARLIER THIS SESSION ARE REFUTED and are corrected in the record:
1. "The damage is flat across epochs and only rotates direction" -- FALSE. ran-on
is non-monotonic (0.38 -> 0.13 -> 0.20 -> 0.28 across epochs 0.49/0.65/0.98/
1.96) with a real minimum near 0.65, and ckpt225 is 48% out-of-band against
ckpt300's 35%.
2. "ckpt300 runs far too short, ckpt225 will clear ran-on by being short" -- FALSE
on both. ckpt225 runs LONG (median 127, 38% over-band) and is the worst arm in
the run. I generalised from SIX generations of one arm, which is the exact n=1
violation the measurement-discipline rule names, committed in the same breath
as a note about being careful.
3. The original "gate an earlier checkpoint, the overshoot may not have arrived
yet" recommendation was RIGHT. Retracting it an hour later on a three-arm read
was the error, not the recommendation.
What is true and unresolved by any checkpoint choice: 35% of ckpt300's generations
miss the 90-140 band against base's 11%, and in-band is 0.65 against 0.89. An
adapter that buys a voice and costs a third of the length compliance is a trade, not
a defect -- but it is the operator's trade to accept.
Raw artifacts for all five arms at scripts/mccarthy-corpus/gate-results/.
720 generations, 3 arms x 60 held-out beats x 4 seeds, against the design frozen
in GATE-PREREG.md before any arm existed.
AXIS A VOICE -- PASS, both candidates, both reads. Span 0.661 -> 0.370 = 0.291
achievable; ckpt900 closed 59.1% (+0.172, but only 1.2x its floor), ckpt450 52.2%
(+0.152 at 2.9x). The normalised secondary read HOLDS at +0.124 / +0.114, so about
three quarters of the gain survives stripping every punctuation mark -- the voice
is not the cheap win the register made available.
AXIS B NOT COPIED -- ckpt450 is the cleanest result in the line. 0.12 hit-rate
against the author's own held-out 0.12, and its longest match (11 words) is
SHORTER than the author's coincidental longest (12). All 96 matched runs were
read: stock grammar in the commonest words, the name-shaped hits are the RENAMED
inventions, nothing protectable. The amendment is why this reads as clean -- the
defective base control would have shown 0.12 vs 0.00 as a 12x red flag.
Separately measured: the "his register makes collisions inevitable" story that
was FALSE for Hemingway (0.01) is TRUE for McCarthy (0.12). Neither transfers.
AXIS C NO DAMAGE -- FAIL, both, and it survives reading. 20% (ckpt450) / 28%
(ckpt900) of generations overshoot the 90-140 band against base's 1%; p90 171/190
words, max 297/279. The worst case is degenerate looping, not a long McCarthy
sentence. Base is GOOD on this axis here (0.89 in-band vs Hemingway's 0.05), so
the adapter measurably makes instruction-following worse.
NOT SHIPPED. Section 7 rule 3 makes axis C disqualifying outright.
Recorded honestly: my own prereg's axis C transcribed score_beats.py's v1
criteria, including "in-band up on base", which the operator RETIRED on
2026-09-15 for exactly the reason it fails here -- base maxes it, so it is
unsatisfiable on this corpus regardless of adapter quality. Under the operator's
v2 (ran-on only) ckpt450 passes by 0.01 against a 0.200 floor. That reading was
found AFTER the numbers and was NOT used; lv-bronte's floor defect is the in-line
precedent for finding one and declining to exploit it. The prereg gets fixed
prospectively for the next author, not re-read for this one.
And the finding worth more than the adapter: the two-epoch recipe is now 0 for 3,
and this time the loss curve was CONFIDENTLY wrong. On Bronte and Hemingway the
epoch-1/epoch-2 checkpoints were tied, so preferring the earlier one cost nothing.
Here the curve resolved epoch 2 as better at 4.9x the median neighbour jitter --
and epoch 2 lost every axis that resolves: 4.0x wider seed spread, 1.8x the
author's memorisation rate against 1.0x, more ran-on, worse on-beat. Its only win
is a 0.019 voice point estimate, inside the floor, and its spread is one outlier
seed -- the third occurrence of that shape in the later checkpoint after
lv-bronte's ckpt925 and lv-hemingway's ckpt1750.
Raw artifacts committed at scripts/mccarthy-corpus/gate-results/ so the claims can
be re-read without gx10.
Archived 15 entries (Recent decisions 14, Tried and abandoned 1) oldest-first
to archival-memory.md; 5 held back on the open-deferred-work guard and 164 on
the 14-day guard, so the index stays over the soft cap at 477 lines. An
over-cap file that keeps live decisions beats a scannable one that lost a
belayed item.
Four new detail files cover the day: the ops log and its four self-inflicted
failure modes, the Booth's two dead controls and the four-iteration layout
probe, the Gitea org grant plus the dead claude-bot token that had been
misreporting permissions, and the disk triage that rescued a LoRA adapter from
a directory this box sweeps at three days.
lv-mccarthy's run outcome remains unverified after two days and is the first
line of the in-flight section and step 1 of the handoff.
Operator confirmed 2026-09-19 that fv-ml1 and the R420 running OPNsense are the
only loads on a dedicated 20 A circuit.
The governing number is 1920 W, not 2400: a GPU inference host running for hours
is a continuous load, so NEC's 80% rule applies. Worst case lands at ~1625 W
with the current caps -- about 85% of budget.
Measured via the BMC rather than assumed: 390 W instantaneous, 461 W max over a
2423 s sample, with GPUs at idle, giving a ~313 W non-GPU baseline.
Compare the GPU caps against the 300 W stock TGP, NOT the 325 W firmware
ceiling. The operator corrected this: 275 W across four cards saves 100 W, not
the 200 W you get by measuring against a number nobody would ever run at. Stock
300 W would put the circuit near 90%, which is not illegal but leaves nothing
for a heavier R420, PSU efficiency, or a warm day. Keep the caps.
The coupling matters more than the trip. OPNsense IS the Fountain Valley edge
and shares the breaker with the thing most likely to trip it, so an overload
takes the router with it and removes the remote path needed to diagnose or
power-cycle anything. fv-ml1's four PSUs do not help -- PSU redundancy protects
against a PSU dying, not against the circuit going away.
Three things are explicitly NOT measured and the file says so: fv-ml1 under real
4-GPU load, whether the BMC reports AC input or DC output, and the R420's actual
draw. Treat 1625 W as a floor.
Also corrects the hardware section, which claimed 2x GPUs. nvidia-smi reports
four.
infra-ops and infra-hermes act as the same OS identity and dockerd does not
log exec per caller, so host-side changes carry no fingerprint. Git cannot
close the gap either: every commit here is attributed to Vuong Hoang by
convention, which is correct for authorship and useless for attribution.
On 2026-09-18 a second session edited the searxng stack mid-deploy, crash-
looping fleet search for ~4 minutes, and the author was unidentifiable.
scripts/ops-log records one line per host-changing action and holds a
lightweight claim so two agents do not deploy the same stack at once.
Four design questions, settled:
* Central on nh3-dev, not per-host and not the post office. Both agents
run as the same unix user there, so one file is shared with zero
provisioning. Per-host needs a writable path on ~25 heterogeneous boxes
and stores "we changed host Y" on host Y. journald looked free but shows
an unprivileged reader only their own _UID, which would have split the
log silently between the infra-ops and lkraven halves of the fleet.
* The claim is advisory and enforced in the tooling. deploy-stack.sh
refuses a foreign claim across the diff, the prompt and the apply -- the
whole review window, which is where the collision happened. Acquire is
mkdir, so it is atomic rather than probably-fine. Stale claims auto-break
and the break is recorded.
* Writers are automatic. deploy-stack.sh and elway record themselves; a log
that depends on remembering is the same class of instrument as a health
check that passes in both states.
* There is a detector. `ops-log audit` asks each host what changed on disk
and compares it to the newest log line for that stack, covering the
manual ssh-and-edit path the automatic writers structurally cannot.
ops-log being absent or broken never blocks a deploy; only a live foreign
claim does. `ops-log baseline` marks the 136 stacks that predate the
instrument so the detector starts from today rather than reporting the whole
fleet forever and training us to ignore it.
An unreachable host reports INCOMPLETE and exit 5, never clean.
Operator ruling 2026-09-19, recorded in three places because each serves a
different reader. CLAUDE.md gets the structural facts so a fresh session has
them without reading anything else; persistent-memory gets the dated decision
and the assigned work; auto-memory gets the durable working relationship.
The division: infra-ops keeps improving infrastructure tooling plus the hard
calls, infra-hermes takes day-to-day checks, triage and routine operations,
either may perform infra ops, and infra-ops may task him downward while he
escalates upward.
He is explicitly NOT Miranda. The global CLAUDE.md names Miranda as the sole
trusted relay of operator authority and that exception does not extend to him,
so a directive he relays is information rather than authorization — reversible
relayed work executes, irreversible or fleet-affecting goes to the operator.
He has acknowledged it in those terms.
⚠ The two handles differ by one character in the middle of a word and the
fleet's OS identity is infra-ops, so a misaddressed page still mails the sender
themselves. That trap is now documented alongside the existing mirror warning
rather than replacing it.
Building the ops log is assigned and not started. Two agents now share one
fingerprint-less OS identity: ssh infra-ops@<host> is either of us and dockerd
exec is not logged per-caller. The precipitating incident is on the record —
2026-09-18, a second session edited the searxng stack mid-deploy, crash-looped
fleet search for ~4 minutes, and the author was unidentifiable because every
commit is attributed to Vuong Hoang by convention. The parked attribution-gap
memory is unparked and points here.
The open design questions are noted as mine to settle, the load-bearing one
being whether deploy-stack.sh and elway write to the log automatically. A log
that depends on remembering is the same class of instrument as a health check
that passes in both states, and this repo spent yesterday learning what those
cost.
An infrastructure day with no training work, and the through-line is that
every fault was invisible to monitoring. NH3↔Anaheim had been crossing a
throttled DERP relay rather than a direct path for long enough to carry 78 GB;
`.internal` DNS was failing roughly one lookup in ten from two independent
causes; SearXNG had exactly one working general web engine. Nothing alarmed on
any of it. All three surfaced because tts-dev had a 1545 ms voice-loop budget
and chose to measure rather than adapt around the problem.
Also landed: althing v3.6.3, which makes hyphenated search work for the first
time on a fleet whose hostnames are nearly all hyphenated; FleetTools, a
capability index autoloaded by Claude, Codex and Grok from one symlinked file;
Miranda's Hermes plugin moved from a copy to a repo symlink; Worldtree's
env.sh secrets vaulted.
Six detail files. The in-flight section is rewritten and shrinks 142 lines to
64 — it opens on the one thing this session did NOT verify, lv-mccarthy's run
outcome, which was left untouched and must not be assumed good.
Two foot-guns recorded, both mine: the ESH egress experiment reverted on a
diagnosis the rollback itself falsified, and `!ENV` in searxng settings, which
has no constructor in that build and crash-looped the container ten times.
No archival this run. 165 of 169 dated entries are under the 14-day guard and
the remaining four all carry open deferred pointers, so the index stays over
the soft cap at 480 lines — an over-cap file that keeps live decisions beats a
scannable one that lost one.
In-flight rewritten to the live training run (~150/1380, ETA ~00:45 PT) with the
--save-total-limit finding that would otherwise have deleted the epoch-1/epoch-2
checkpoints both prior gates were decided on.
Two decisions added: the next-seat ranking (Faulkner, Morrison, Chandler -- and the
finding that the corpus size ranking inverts the voice ranking, with King and Christie
as the two biggest non-candidates), and the romantasy register measured on the gate's
own char-bigram instrument (Yarros is the cluster outlier we already shipped; Maas is
the centroid and so the worst pick; Kenyon at 27 val units if the lane gets a seat).
Auto-archival: 4 entries moved to archival-memory.md; 4 held back by the open-deferred
guard.
Operator ruling: "he's a great writer because of his research, not because he has a strong
identifiable voice."
That reason is about the AUTHOR rather than the data, and it is the better of the two on the
table -- the other being the unmeasurable fraction of quoted material. It also names a
selection criterion this line did not have: ask whether there IS a voice worth adapting
before investigating whether a clean corpus can be built. That question was never asked here.
I surveyed the holdings, built the corpus, measured all fifteen containment pairs, and fixed
three stripping defects the name guard caught -- all real work, none of it touching the thing
that decided it.
A voice adapter is worth its corpus-plus-training-plus-gate only when the target has a prose
signature a reader could pick out blind. McCarthy: 0.0 quote marks per 10k against Hemingway's
838. Hemingway: spare declaratives, heavy unattributed dialogue. Brontë: periodic sentences
built on semicolons and dashes. If that sentence is hard to write, the author is a park.
Nothing is deleted. The corpus (126 units, 422,880 words) and the builder stay committed and
re-runnable; the park entry records what exists, what was never started (D2), and what would
unpark it -- a re-extraction preserving indentation and italics, which would fix the quoted-
material problem but not the operator's objection. The builder's own docstring now carries a
stop notice so a future session finds the reason at the artifact rather than only in memory.
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.
In-flight rewritten for the next goal. lv-hemingway is TRAINED and nothing else
has been done to it: ship candidate is checkpoint-1750 (ep 1.97, eval 2.2783),
the end-of-run adapter is 0.0763 worse, and the v2 gate has not been run. Every
instrument it needs was parameterised during the lv-bronte run tonight and the
in-flight section names all four with their traps.
New detail files:
2026-09-17-lv-bronte-gate.md shipped, voice axis failed, why anyway
2026-09-17-beat-contamination-leak.md the leak the corpus gate cannot see
2026-09-17-esh-fiber-outages.md two Cityside failures, rotation fragility
Also commits the memorization_check.py parameterisation, which was left
uncommitted: its hardcoded Yarros defaults would have compared a Hemingway arm
against the Yarros corpus and reported a meaningless clean zero.
Auto-archival: index was 415 lines pre-run, over the 300 cap. Only five entries
cleared the 14-day age guard, and three of those carry open deferred pointers
(fused MoE park 47, nconnect=8, AI-tab belayed) and are referenced by in-flight.
A fourth — every CI job on pfi-fleet runs as root on ana-docker — is a live
security property rather than settled history, so it is held back deliberately.
One entry archived. The file stays over cap, which is the guard working: an
over-cap file that keeps live decisions beats a scannable one that lost them.
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.
Records the full v2 gate result and three findings that outlive the ship call:
1. The effect is UNDERPOWERED, not absent. Both candidates closed 48-52% of the
achievable span to held-out Bronte and beat base on every individual seed, but
the gaps sit under the measured floor. Sensitivity floor stated so the negative
is falsifiable: cannot resolve better than ~0.251 delta_cb at 30 beats x 4 seeds.
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.
2. A DEFECT IN THE v2 RULE. The floor is the largest within-arm spread across ALL
arms, so adding a third noisier arm raised the bar that failed the clean one.
Run as a two-arm gate the floor would have been 0.092 and the candidate would
have cleared at 2.1x. Deliberately NOT exploited — choosing the floor that
passes your preferred answer is the failure pre-registration exists to prevent —
but the rule should state whether the floor spans the compared pair or every arm
present. As written, a verdict depends on which other arms you happened to run.
3. The two-epochs-on-a-three-epoch-schedule recipe did NOT transfer. Bronte's two
minima are 0.0022 apart against a 0.0046 jitter; epoch 2 buys nothing over epoch
1. The epoch-3 collapse (+0.075, ~16x jitter) is the only robust part.
The outlier seed was diagnosed rather than waved away: a repeat-5gram degeneracy
probe is uniform at 0.0078-0.0102 across every seed and both arms, so it is genuine
delta_cb variance and the floor stands.
Incremental over 653f7fb, covering the three turns since.
breeze-tts stays on irv-ml1 and the TTS-stack move is parked at id 75. Adds the
full fv-ml1 per-seat residency table and the shuffle arithmetic behind the
recommendation: every arrangement that makes real room on GPU 1 spends the GPU 3
reserve anyway, so if breeze ever moves it should go straight to GPU 3 rather than
evacuating three working seats for the same cost plus a migration.
The finding worth keeping is that --gpu-memory-utilization does not predict resident
VRAM, and is wrong in both directions: cyberprev at util 0.40 holds 8 GB more than
its fraction, gen-small at 0.48 holds 10 GB less. An hour earlier in the session I
reasoned about placement from those fractions and would have been 8 GB out. Read
nvidia-smi --query-compute-apps instead.
Also records a characterized defect in this skill's own handoff generator. Across
two runs in one session it converted operator-deferred items into an imperative
next-steps list and twice invited the next session to commit files marked as
predating it. It fails in the blind spot of the documented fail-loud posture: the
output is structurally valid and exits 0 while inverting the intent. That matters
more than an ordinary bad summary because the handoff is the one artifact a fresh
context reads as instruction. Both runs were corrected in-session; not yet reported
to the skill's owner.
Operator ruling: leave breeze-tts on irv-ml1 and park moving it, bragi and
tts-gateway to fv-ml1 until the embedder, reranker and reward seats are evacuated.
Parked as move-the-tts-stack-breeze-tts-bragi-tts-gateway (id 75) with the trigger,
the footprints and the migration gotchas, so it resurfaces with everything needed
rather than as a bare line.
Two things worth having recorded against the trigger. All three services move as a
set because only breeze is GPU-resident at ~10.3 GiB and growing, while bragi and
tts-gateway are CPU-only proxies - co-location with the gateway is the entire reason
not to move breeze alone, since that is what puts a cross-site hop on every TTS call.
And the trigger as stated names gpu0, but vllm-embed, vllm-rerank-a3 and vllm-reward
are all pinned to GPU 1. GPU 1 is the constrained card at 0.975 committed with
4,336 MiB free, while GPU 0 has 11,982 MiB free and carries the live chat path, so
evacuating those three relieves GPU 1 rather than GPU 0. Recorded as a
confirm-before-executing rather than silently corrected, since it changes where the
TTS stack would land.
Also notes that bragi and tts-gateway reach each other by name only through
extra_hosts pins, because containers on irv-ml1 cannot resolve nh3.internal - those
pins travel with them and need re-pointing at the new host.
