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.
Stoplisting a surface removes it from the entity map, so rename never touches it
and the gate never scans for it. That is exactly what a stoplist is FOR when the
surface is a real-world referent — and exactly how a wrongly stoplisted CHARACTER
becomes an undetectable leak. The gate reports 0 of N surviving and is telling the
truth about the set it was given.
Found by luck on lv-bronte: a generated beat said "Mrs. Leaven", and Leaven had
been filed under scripture as the bread noun. Reading it back: "Robert Leaven,
the coachman" — Bessie's married surname in Jane Eyre.
Running the audit instead of trusting that luck caught two more:
Pierrot "Madame Pierrot: she comes from Lisle, in France" — a teacher in
The Professor, filed as the commedia dell'arte figure
Samuel "Mr. Samuel Wynne" — filed as scripture
and correctly CLEARED two:
Wellington "that Baal of a Lord Wellington" — the real Duke
Moses "the Rev. Moses Barraclough" — the documented dual-use
Signal is an honorific in front of the surface: real-world referents are not
addressed as Mr/Mrs/Miss/Madame/Lord. It is a heuristic and not a proof, which is
why every hit is REPORTED FOR READING and never auto-removed — Wellington and
Moses both trip it and both are correct. Exit 1 on anything not on --allow, so it
can gate a pipeline.
Blast radius of the three errors was 16 of 3781 train pairs and 3 of 80 val —
small, but they are the author's characters in training data, which is the one
thing this pipeline exists to prevent. Corpus rebuilt rather than dropping the
affected pairs: a corpus on disk that disagrees with its committed config is how
superseded claims get made. Gate re-passes at 0 of 368 (three more surfaces than
before, exactly the restored characters), both controls green.
Two harness defects that would each make a voice number uninterpretable.
build_beat_fixture.py — the fixture is now SAMPLED from the val split rather than
hand-written. The original BabyYarros fixture was five hand-written beats about a
stray dog and a kitten: wrong genre, so 'He licked her clean' came back as
explicit sex from a romantasy adapter, and n=5 had a noise floor of 0.800 that
manufactured a +0.45 result which collapsed to +0.08 at n=120. Sampling from val
makes it in-genre and held out by construction, spread across works so a naive
head(30) is not one novel. Refuses outright if the pairs carry any split but val,
because a fixture drawn from training data makes every downstream number a
memorisation measurement wearing a voice label.
gen_beats_chat_yarros.py --system-from — the SYS constant in this harness is
Yarros's. Driving a Bronte or Hemingway adapter with it measures the arm under a
system prompt it was never trained on and confounds the carrier change with a
prompt change. Rather than duplicate the register table and rely on whoever runs
it to pick the matching one, read the prompt out of the pair build's own
provenance, which is the artefact that records what the adapter actually saw.
Records the reproducible chain and, more usefully, why it diverges from the
Yarros/Hemingway pipeline in five places, each forced by a measurement rather
than a preference.
Includes the control post-mortem, which is worth keeping because in three of
four cases the CONTROL was wrong and the detector was right — the opposite of
the reflex. Adele vs Adele-with-a-grave, Hollow at a 0.235 lowercase ratio, and
Grace at 0.224 were all correct refusals. Blanche, at 0.0526 against a 0.05 bar,
was the one real detector miss.
A leak the corpus gate structurally cannot see, found on lv-bronte.
The rename strips the author's names from the prose and leak_gate.py proves
they are gone — 0 of 365 surviving on Brontë, both controls green. But the beat
is written by an LLM that READ THE PASSAGE, and if it recognises the book it
supplies the canonical names out of its own training. The beat is the
INSTRUCTION half of the pair, so training on it re-teaches exactly the
inventions the rename pipeline exists to remove, and the gate never looks at it:
the gate reads the corpus and the renamed copies, never the generated beats.
MEASURED on the first 714 Brontë pairs, before the filter existed:
13 beats (1.8%) named source characters — Rochester x6, Jane x3,
Brocklehurst x2, Beck, Fairfax, Helen, Burns, Eyre, Reed, Rivers
0 of 714 RESPONSES did. The rename was perfect; the instruction side was not.
One beat read "Saoirse confirms Rochester's flaws, then agrees in English to
marry him" — a renamed name and a canonical one in the same sentence, which is
the mechanism in miniature.
Exposure scales with how well the generator knows the book, so it is WORST for
public-domain classics and mildest for recent work. That is exactly why the
Yarros and Hemingway runs came up clean and Brontë did not — their clean runs
are NOT evidence this cannot happen to them, and both should be rebuilt with
--source-entities if they are ever regenerated.
Adds a `sourcename` reject to vet() plus --source-entities, which takes the
UNRENAMED entity map and refuses any beat naming a surface from it. Firing at
roughly 3% of attempts on Brontë.
Also adds a `bronte` register. Brontë is the far end of the same axis from
Hemingway and the register has to say so, or the beat-writer produces modern
summary prose the passages never match.
The Brontë corpus's "0 of 203" was a HAND COUNT made before leak_gate.py
existed. On Yarros the automated instrument read 212 surviving where a hand
count said 86, so the hand count was never evidence. This runs the real gate,
and getting it to pass required fixing four defects the hand count could not
have seen.
CORPUS DEFECTS (repair_corpus_bronte.py, both measured):
- 1,922 words of publisher back matter inside Shirley's last unit — a
T. Nelson & Sons catalogue advertising Ainsworth, Marryat, Verne, Kingsley
and Dickens, plus a Gutenberg transcriber's punctuation list. Not Brontë,
and the source of the entity CHARLES. Same structural cause as the
Hemingway run: a splitter cuts on headings, nothing follows the final one.
- 1,368 Gutenberg italic spans. Two harms: they teach the adapter to emit
underscores, and the underscore is a word character, so the gate's
word-boundary scan cannot match inside an italicised name. An entity in
italics is invisible to the gate — the same never-renamed-AND-never-
reported shape as Yarros's possessive-only Afendra.
DETECTOR GAPS (phrase_map_bronte.json):
- Blanche is 19 capitalised against ONE lowercase — ratio 0.0526, over the
0.05 bar by a single token, so a named character with 19 mentions is
dropped by a hair.
- Grace (0.224) and Hollow (0.235) are refused correctly — both are common
nouns — but Grace Poole and Hollow's Mill are Brontë's. Sampling all 21
bare capitalised Grace found 20 are the character in direct address and
exactly one is the theological noun.
- Five compounds whose every component is non-renameable survive verbatim:
Moor House, Marsh End, Vale Hall, Bigben Close, Royd Lane. The other 77
audited phrases do not, because each has a renameable component.
GENDER (pin_known_gender.py): the inherited resolver put Jane MALE across 336
occurrences. Hemingway's base-rate resolver is strictly better here (1 wrong vs
4) but still fails on Jane, and the failure is structural, not tuning — Brontë's
three narrators are first-person, so their names appear almost only in dialogue
surrounded by other characters' pronouns. Ground truth is pinned separately from
the resolver's evaluation so the two are never conflated.
Also: min-cap lowered 8 to 3, which pulled Bertha, Ferndean, Rochesters and
Creemsvort in from below the old floor; corpus-scope rename so a name below
threshold in one novel is not printed verbatim there while renamed in another.
Gate: 0 of 365 surviving, positive control 365/365, negative control clean,
phrase audit 0 of 82. Floor stated: 3 capitals per work, 5 recurrences.
Adds playbooks/update-stack-image.yaml — pull the newest image for one
compose stack service and recreate it, with a verify phase that asserts
the container's image id equals what the tag now resolves to rather than
trusting a 'Up' line from docker ps.
Scoped to a single service on purpose: the recreate is 'up -d <service>',
never a bare 'up -d', which would recreate every service in the project.
Go template format strings are written bare; elway's {{ identifier }}
substitution leaves them alone, but {{end}} / {{else}} would match and
die as undefined variables, so the health read uses {{json .State.Health}}
instead of an if/else.
First use: drawio on esh-docker-vm, 28.1.2 -> 31.4.6.
Sent with both specimens. Adds the root cause, which is in SYSTEM_PROMPT rather
than the model.
Next steps is the only one of the three generated sections with no empty case.
Watch out for is told to omit itself when there are no gotchas and Resume here is
told what to say when nothing is in flight, but Next steps is told only that it is
a numbered, ordered, concrete list. With nothing in flight the sole action-shaped
nouns in the input are the deferred items, and the nothing-in-flight rule points
the model straight at them by asking it to name the most recent open pointer.
Nothing in the prompt protects modality. Invent nothing and trace every claim to
the input are both satisfied - the items really are in the input - while their
deferred-ness is exactly what gets dropped. The verbatim-identifier rule already
establishes that some attributes of the input must survive restructuring untouched;
modality is one of them and only identifiers are guarded.
Proposed two prompt changes to galdrabok: an empty-case escape for Next steps, and
a rule making deferred, parked, belayed and deliberately-not-done items constraints
belonging in Watch out for rather than steps. Offered as a caller's diagnosis since
the skill is theirs. Noted that galdrabok-dev is pull mode, so there is no herald
poke and they will see it on their next check.
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.
The operator asked this mid-sweep and the answer never reached durable memory -
caught only because he asked again after the snapshot. Recommendation is not to
move it.
Re-measured rather than reciting the earlier figure, which was right when taken and
is now wrong: breeze holds 10,316 MiB after 53 minutes of uptime against 9,218 MiB
shortly after warm-up. The footprint grows with use, consistent with PyTorch's
caching allocator not returning memory - probably caching rather than a leak, but
resident either way and counting against any neighbour. Two points is a trend, not
a curve; whether it plateaus is unmeasured and stated as such.
That changes the placement answer. fv-ml1 GPU 0 has 11,982 MiB free, so the margin
is 1.7 GB and shrinking rather than the 2.8 GB the earlier number implied, on the
card carrying the live chat serving path.
The stronger objection is topology rather than VRAM: tts-gateway runs on irv-ml1
and reaches breeze on the same box, so moving breeze alone puts a cross-site hop on
every TTS call against a 478 ms to-first-sample budget. Moving it properly means
moving the gateway too. It is also not constrained where it sits - the 3090 still
has 10 GB free.
Also records the trap that nearly produced a wrong number: breeze reports nothing
at idle when queried on the wrong GPU, because BREEZE_GPU_DEVICES=0 is the 3090
rather than the A6000. An idle query of the A6000 shows it absent entirely.
Closes both of the previous session's named jobs and six unplanned pieces of work.
Nothing is in flight and nothing is blocked.
Parakeet STT live on fv-ml1 GPU 0 behind LiteLLM ext-stt and whisper-1; GPU 3 is now
a documented reserve after the operator caught an 800 MiB seat parked on the one
pristine 96 GB card. svos_miranda enabled and Miranda serving, with
agent.disabled_toolsets deleted and staying out by operator ruling. talk v10
deployed as the STT seat's first consumer. The irv-ml1 dead-address sweep is
complete at 0 of 112 Homepage cards, having turned up four live breakages on other
hosts. The secrets-broker concurrency bug is fixed, and ~/.local/bin/secret is a
symlink rather than a stale copy.
Auto-archival fired at 433 lines but moved only one entry: three of the four
candidates old enough to qualify carry open deferred-work pointers - a park id, an
althing thread, and an explicit 'untracked by operator choice' - and the guard held
them. The index stays over cap at 389 lines, which is the correct trade: nearly
every entry is genuinely under fourteen days old.
The generated handoff needed correcting in-session before it shipped. The model had
turned three operator-deferred items into a to-do list and invited the next session
to commit files that predate this one. Both would have read as instructions to a
fresh context, which is the durable-false-warning failure this session spent the day
documenting.
Vuong asked me to find and fix the harness issue blocking tts-dev from deploying
talk. There was no harness issue, and no issue of any kind.
/opt/docker/compose on nh3-dev is root:docker 2775, agent sessions run as lkraven,
and lkraven is in the docker group. A mkdir settles it in one second and nobody ran
one for nine days. There is also no tts-dev OS account, so the group request had no
referent.
It held together because a stale persistent-memory row supplied a plausible
mechanism and the operator's routing instruction - 'give it to infra' - was read as
corroboration of a capability limit. Those are different claims and only one was
ever stated: a routing preference explains where work went, never whether it could
have gone elsewhere. A contradicting ls -la was on screen in the same session and
was dropped. I then repeated the claim to the operator as fact in a deploy report,
which put a second name behind it.
Then I did the same thing one layer up. Finding no OS problem and no deny rule, I
inferred an auto-mode classifier refusal because the shape fit, and committed a
settings.json into tts-dev's repo on that inference. Their mkdir showed the path
writes with no refusal at all, so the hypothesis was wrong and the commit is
reverted. I had spent the night writing up this failure class and still built a fix
for a layer nobody had shown me failing.
That commit also claimed a doc correction it did not contain: the edit and the
commit were chained in one invocation, the edit's anchor assertion failed because
the target text had already been fixed, and the commit ran regardless. Amended
before reverting. Never chain an edit and its commit in one invocation.
The rule worth keeping is that 'I can't do X' from any source is a hypothesis until
someone runs the command and pastes the error, and that 'there is no error text,
because there was no error' is a possible answer.
svos-dev observed that three instances of the same shape turned up between two
agents in one night and that it is starting to look like a characteristic failure
rather than a coincidence. Collecting all nine from today, because the class is more
useful than any instance.
The shape is a check that reads the input to a transformation and gets reported as
if it read the output - or more generally, the instrument answering instead of the
system, in a form shaped exactly like a real answer. What makes it expensive is not
that things break but that the broken state is indistinguishable from a legitimate
one, so it passes review and is found later by accident. Every one of the nine
passed a check.
The tell is stated so it can be recognised prospectively: whenever 'broken' and
'legitimately empty, absent or off' produce the same output, the cheap check cannot
tell them apart by construction.
Remedies that actually worked today: measure the output rather than the input;
positive controls, since a method that has only ever passed cannot tell you it is
not blind; true-negative controls, because two apparent failures in the
secrets-broker test were names I had invented and would have been read as a partial
fix; refuse to emit the ambiguous value, which was the real fix rather than the
lock; and do not declare victory on a plausible fix, which is the only reason the
session-establishment root cause was found at all.
Reported by svos-dev after parallelising four vault reads in SVOS's systemd
wrapper. Reproduced here and it is worse than reported: four concurrent secret get
calls for distinct items returned empty strings with exit code 0, zero of four
succeeding against their one of four. No error, no timeout, no diagnostic.
The shape is the problem, not the race. A caller treating an empty optional secret
as 'not configured' degrades silently and never learns otherwise - it cost SVOS the
ability to page the operator while the process logged a clean startup line.
Root cause is session establishment, not item reads. Every invocation runs bw
unlock, and concurrent unlocks against the shared appdata dir invalidate each
other. The damage then surfaces downstream as an empty listing or an empty item
body, which is why a per-call lock is useless: by the time the read runs the
session it holds is already dead. So the lock wraps the whole command instead.
Three changes. The command-level lock makes concurrent callers queue. cmd_get now
refuses an empty value rather than printing it, since a stored secret is never
legitimately zero-length. And find() no longer coerces empty stdout to '[]' - that
turned a broken read into a confident 'no such secret', the same silent-wrong-answer
shape one layer up.
Verified: four parallel reads of four real items now return all four correctly,
serialised at the honest ~17s each. A name that genuinely does not exist still
fails loudly, so the guard did not simply mute the negative case.
Also replaces the copy at ~/.local/bin/secret with a symlink to this file. It was a
plain copy in sync by luck, and every edit here silently left the live tool behind.
Operator-directed. The wg0 lifeline retired at the 2026-09-06 headscale cutover is
on no interface anywhere, so anything pointing at it gets no route at all. Homepage
went from 9 dead cards to 0 of 112.
The load-bearing part is that there is no single right target: it depends on who
resolves it. The operator's browser and the Homepage and open-webui containers on
esh-docker-vm all resolve nh3.internal, so those get the name and survive the next
renumber. Containers on irv-ml1 and ana-docker cannot resolve it at all, so those
get the IP.
litellm on ana-docker looked like a counterexample and is not: it resolves the name
only through its own extra_hosts entry, while asset-engine on the same host fails on
it. Test from the container you are about to change, never from a neighbour. Before
committing to the name I confirmed the Homepage container actually fetches ytvc's
healthz through it in production rather than assuming resolution implies reach.
On irv-ml1, 24 files swept and 14 comment-only hits left as port-allocation history.
Seven running containers recreated so the labels took. Seven dormant ones carried
stale labels because editing a compose file does not touch an existing container
object - fixed with compose create --force-recreate, which rebuilds the container
without starting it, the right tool for a deliberately dormant stack.
The sweep's real find was off irv-ml1 entirely: four live values on two other hosts,
silently dead for nine days and alerting nobody. Open WebUI's read-aloud TTS,
asset-engine's inference host, and two skaldsong TTS URLs. Both running services were
recreated and verified reaching their targets afterwards rather than merely carrying
the new string.
One self-inflicted outage worth recording: I recreated breeze-tts for a cosmetic
label change and took ext-tts down for its ~90s CUDA-graph warm-up, returning 500. I
caught it only because I had taken a baseline before touching it. A label-only edit
still costs a full model reload on a GPU container.
They adopted the gate as tts-stack tools/gate_served_page.py and extended it in a
place that matters: my version would have passed a broken page.
A worklet lives inside a template literal, so a syntax error in it is invisible to
a parse of the enclosing script - it is just a string until addModule compiles it
at runtime, where it fails as a rejected promise and the page quietly falls back to
buffered playback or records nothing. Silent degradation, which is harder to notice
than a dead page rather than easier. They parse the worklet separately, and they
positive-controlled the whole thing against two deliberately broken pages rather
than assuming a gate that has only ever passed is not blind. The second control -
valid enclosing script, broken worklet - is the one my version fails.
The lesson on my own work is the useful part: I built a gate for the failure I had
just been shown and stopped at its boundary. The class is 'code that is a string at
parse time and code at run time'; an inline script is one instance and a
template-literal worklet is another. I checked the instance, not the class.
Also promotes the underlying rule to the index, since it was named twice tonight
from two unrelated directions: a check that reads an artifact as stored cannot see
a transformation that happens between storage and execution.
Operator-instructed via tts-dev. First consumer of the ext-stt seat stood up the
same night - talk can now listen as well as speak. Relayed authorization was fine
to act on because the work is reversible: one-line tag rollback, v1..v9 retained,
compose and .env backed up. Checked the escape hatch existed rather than believing
the message that described it.
Gated properly: build, throwaway on a non-live port, four acceptance checks, tear
down, then cut over in a separate invocation. Re-ran all four against production
afterwards, because a gate that only ever ran against the throwaway proves the
image rather than the deployment, and confirmed the two new env vars inside the
running container rather than in the file.
Added a fifth gate worth keeping. tts-dev's worst bug this cycle was a JS escape
inside a Python string arriving transformed, closing the string and killing the
entire inline script while the page still rendered and both import and node --check
passed - because the file still held the backslash. So: fetch the page over HTTP,
extract the inline script from the response body, and node --check that. Same
instrument pointed at the other side of the transformation, and over the wire it
also catches anything that mangles the body after TLS and ASGI.
That is the second instance tonight of one rule: a check that reads the artifact as
stored cannot see a transformation between storage and execution. provider=cuda in
a log is the same error - an echo of configured intent read as a measurement of
running reality.
Also notes an open question for the operator: talk deploys route through infra-ops
only because tts-dev's identity is not in nh3-dev's docker group. The durable fix is
a group membership, not a standing relay.
svos-dev restarted :8770 at 02:17 and both roster lines printed clean. Confirmed
from this side rather than taken on their word: :8770 answers 200 on the new pid,
an unauthenticated Bifrost dispatch gets 401, and Hermes reports 29 toolsets with
svos_miranda the sole enabled=True row.
Two patterns from their restart that generalise past this service.
A dry-run boot against the still-held port: start the new process while the old
one still owns the socket, and it proves every check above the bind before dying
on EADDRINUSE. Zero downtime, no commitment, and it turns a one-way restart into a
rehearsed one. Worth doing for any service whose startup validates before binding.
And a trap: SIGTERM released the port but left the process alive for 35 seconds,
needing SIGKILL. The port was free that entire time, so a script waiting on port
availability would have started the replacement alongside a still-running old
process. Kill by PID and wait on the PID, never on the port - a freed port is not
evidence of a dead process, the same way an unreachable post office is an outage
rather than an empty inbox.
The IRV seat was retired on tts-dev's numbers: it lost to the FV seat at both
clip lengths and to whisper-large-v3 at 6.24s. Their length sweep fits ~58ms
fixed + 56ms per audio-second with an asymptote of ~17.8x realtime, which
independently reproduces our 17x on a different clip and harness, and the gateway
hop measured below their harness resolution so ext-stt is the right consumer path.
Two caveats recorded against our own numbers: their between-run variance is 20%
because GPU 0 carries the live chat path, and our 0.50s median came off an idle
GPU 3 - a best case, not a comparable.
Their RTFx retraction is the durable part: published RTFx is batched throughput on
datacenter hardware rather than single-stream latency, and the two differ by ~200x.
Also banks the shape their acceptance gate caught, because it generalises past
their repo. A JS escape inside a Python string arrives transformed, closing the
string and killing the whole inline script, while the page still renders and both
import and node --check pass - the file still holds the backslash. That is the
same failure as reading provider=cuda out of a log: a check that reads the
artifact as stored cannot see a transformation that happens between storage and
execution. Both check the input to a transformation and get reported as if they
checked its output.
svos-dev landed c9d2a96 - build_miranda_roster now returns an empty disabled list
unconditionally and the startup line no longer names the key. The 28-name list is
removed from ~/.hermes/config.yaml rather than left commented, since a paste-ready
array behind a hash is what a future session uncomments; a short warning stands in
its place.
Their mechanism is better than mine and replaces it in the record.
_get_platform_tools resolves platform_toolsets first and applies global suppression
last, so subtracting 28 names from a one-element platform set is a no-op by
resolution order - not merely 'adds no safety on top'. That holds for any future
platform; the measurement only established the single case.
And the endpoint already carried the answer. _handle_toolsets computes each row's
enabled as membership in the per-platform set, so verified live: 29 rows with
svos_miranda the only one reporting enabled=True. A check reading that field rather
than counting rows was correct all along, against a config that never needed the key.
Four operator rulings executed.
svos_miranda is live in Hermes. Gateway restarted 02:10 (PID 3107822 -> 3901622,
confirmed by observing the change). /v1/toolsets now reports 29 rows including
svos_miranda, and an api_server session resolves to exactly the 8 plugin tools
with the write-klass five absent.
agent.disabled_toolsets stays off permanently: 'i dont want the tools disabled
everywhere'. That key is a global end-of-pipeline subtraction rather than an
api_server-scoped one - measured, a default session goes 46 tools to 20 - and it
is unnecessary anyway, since platform_toolsets.api_server alone produces the exact
8-tool surface. The operator's own session was verified intact at 46 tools after
the restart, which was the point of the ruling.
The consequence is now SVOS's to absorb: it must stop verifying against the global
roster before it restarts, because that roster is 29 by design and will not shrink.
Two workable options went to svos-dev - verify the api_server surface instead, or
relax the check to 'svos_miranda present and write-klass absent'. The second also
survives any unrelated plugin landing on this host, which matters because 'stt'
already appears in that endpoint's rows while resolving it logs 'Unknown toolset'.
irv parakeet retired: it lost tts-dev's bench to the FV seat at both clip lengths
and to whisper-large-v3 at 6.24s. Checked for consumers first - no gateway alias
pointed at it, and every other reference on that host was a comment in a
port-allocation register. Retirement banner on its README names the replacement.
voice-studio stopped: it existed for the dots mint loop and Breeze obsoleted dots
on 2026-09-06, so it was retired rather than repaired.
Two corrections and one finding from the same night.
voice-studio: operator ruled the stack out of service. It existed for the dots
mint/audition loop and dots was decommissioned 2026-09-06 when Breeze took the
fleet seat, so its reason to exist went with it - which is also why nine days of
breakage alerted nobody. No v11 rebuild. The gate one-liner was applied minutes
before the retraction landed and was left in place rather than reverted, since
the value it replaced was a dead address and reverting is another recreate of a
stack that is going away. Container not stopped: it was already running, and
'down for now' arrived as a relayed paraphrase rather than an instruction.
The two host-level facts survive the stack. Containers on irv-ml1 cannot resolve
nh3.internal at all, so on that host the DNS name is the WRONG fix for a dead-IP
bug - it swaps a dead address for an unresolvable one. Confirm resolution from
inside the container before recommending a name. And a stale link can have more
than one drift behind it: voice-studio had three stacked, two of them invisible
from the host compose file.
Hermes: svos_miranda is installed and enabled in config but the gateway was NOT
restarted, so it is not live. agent.disabled_toolsets as specified by svos-dev is
not scoped to api_server - it is a strict end-of-pipeline subtraction applied to
every session on every platform. Measured: a default session goes 46 tools to 20,
losing memory, file, terminal, web, browser and more. It is also unnecessary:
platform_toolsets.api_server alone resolves an api_server session to exactly the
8 svos_miranda tools. The line buys only SVOS's startup check, which reads a
global endpoint to verify a per-platform property. Left commented out with the
measurement inline so an incidental restart cannot gut the assistant.
tts-dev benched both endpoints against a Whisper baseline. FV wins at both clip
lengths (155/391 ms vs IRV 354/1010 vs whisper-large-v3 457/690) — IRV is slower
than the incumbent at 6.24 s, so the duplicate seat is now retirable on evidence
rather than on tidiness. Their length sweep fits ~58 ms fixed + 56 ms per
audio-second, asymptote ~17.8x realtime, independently reproducing our 17x on a
different clip and a different harness. The gateway hop measured below their
harness resolution, so ext-stt is the right consumer path.
Two caveats recorded against our own numbers: their between-run variance is ±20%
because GPU 0 carries the live chat path, and our 0.50 s median was taken on an
idle GPU 3 — marked as a best case, not a comparable.
Also records tts-dev's retraction, which is the durable lesson: published RTFx is
batched throughput on datacenter hardware, not single-stream latency, and the two
differ by ~200x. Their plan had projected 60-120 ms from it.
Separately, chasing the one stale Homepage href they flagged turned up 96
occurrences of the retired wg0 lifeline 10.100.79.3 under /opt/docker on irv-ml1.
Most are cosmetic, but voice-studio is genuinely broken: it is configured to reach
studio-gate at that address, both are running, they sit on separate docker
networks, and the address is on no interface on the host. Failing since the
2026-09-06 cutover with nothing alerting. ext-tts verified unaffected.
Not fixed here — eight containers to recreate, three load-bearing, and the
voice-studio repair touches app.py rather than config. Surfaced with evidence.
The pattern is the third of its shape: a retired address needs a repo-wide grep by
ADDRESS rather than by hostname, and container labels live in no file the sweep
reads until the container is recreated.
Placed on GPU 3 first because it was the empty card. That was the wrong read:
the seat is ~800 MiB, under 1% of a 96 GB card, so the question was never "where
does it fit" but "whose headroom is cheapest to spend".
vLLM sizes its KV cache as a fraction of TOTAL VRAM, not free VRAM. A resident
tenant on an otherwise-clean card therefore does not cost its own megabytes — it
costs the profiling margin of whatever full-size seat lands there later, and
flash-next needs 93 GiB of 96. A 96 GB card at 2 MiB can still take that; the
same card at 922 MiB is one where the next big seat needs its utilization
hand-trimmed, which this repo's flash-next history shows is both thin and silent
when it goes wrong.
Committed utilization per card is the number that governs, not free bytes:
GPU 0 0.40 + 0.48 = 0.88 ~13 GB spare <- moved here
GPU 1 0.52+0.24+0.10+0.055+0.03+0.03 = 0.975 ~4.3 GB
GPU 2 0.96 ~1.8 GB
GPU 3 - kept empty as reserve
GPU 3 is back to 2 MiB / 97,247 MiB free and is now documented as a deliberate
reserve rather than a spare.
Post-move n=5 on the same clip: 0.68 / 0.54 / 0.54 / 0.52 / 0.53 s, median 0.54 s
against 0.50 s on GPU 3. The spreads overlap at this sample size and no difference
is claimed; the GPU 3 figure was taken on an idle card and is now noted as a best
case, since the seat shares GPU 0 with the hot serving path. Silence control and
the gateway round-trip both re-verified after the move.
Also records both Parakeet endpoints (FV v3 on Blackwell, IRV v2 on a 3090) and
the four confounds that make them not an A/B pair, sent to tts-dev for the bench.
Retargets the existing sherpa-onnx stack from irv-ml1 to fv-ml1's utility card
and puts it behind the gateway. GPU 3 was the only card with room: 0/1/2 carry
the vLLM seats at 84-95.5 GB of 96.
Changes:
- compose: pin GPU via `device_ids: ["3"]` (the dead on-host stub used
`count: all`, which would have handed a 0.6B ASR seat all four cards);
join traefik-net; port 8300; homepage href to the live FV address.
- .env.example: default to the v3 int8 model (25 European languages, 464 MiB)
rather than English-only v2; models to /tank/parakeet/models.
- app.py: warm the recognizer at startup before uvicorn accepts traffic.
The warmup is not an optimisation. ONNX Runtime's CUDA EP compiles and autotunes
lazily on the FIRST DECODE, and on sm_120 that measured 45.7s cold (reproduced at
45.1s on a second container) against ~0.50s warm. A 45s first request is
indistinguishable from a hang and LiteLLM's default timeout abandons it long
before it returns. Decoding 1s of silence at load moves the cost inside the
healthcheck's 300s start_period; first real request after restart is now 0.65s.
Verification, because "provider=cuda" in the log is only an echo of the env var:
ORT falls back to CPU silently and still returns correct text, so the service
being up and the transcript being right establishes nothing. The discriminator is
a process on GPU 3 (922 MiB), confirmed. Controls both directions — a known TTS
sentence transcribes near-exactly (positive), 3s of digital silence returns
empty (null). Warm throughput 0.50s median on an 8.52s clip, n=5, spread
0.47-0.65s, single-stream, one clip: a smoke measurement with its harness
stated, not a benchmark.
Gateway aliases `ext-stt` (engine-neutral, mirrors ext-tts) and `whisper-1`
(OpenAI-compatible drop-in) registered via POST /model/new, i.e. LiteLLM's
Postgres store where the ext-tts family already lives — no gateway restart, and
config.yaml is consequently not a complete picture of what the gateway serves.
Both verified end to end.
The aliases use a raw IP deliberately: ana-docker resolves no .internal names at
all (resolv.conf points at 1.1.1.1), and LiteLLM only reaches irv-ml1 through a
hand-pinned extra_hosts entry. A second hosts entry would mean recreating the
container and bouncing the gateway for every consumer.
Also records the svos_miranda plugin validation pass and its structural findings,
and notes that the irv-ml1 parakeet is still running — there are two now, and
retiring the old one is the operator's call.
Captures the close-out of the fleet networking session: mesh membership retired
for both fv-ml1 and nh3-dev, leaving six nodes that each have a job, with
fv-ml1 carrying a break-glass rejoin instead of standing membership and exactly
one live reusable pre-auth key left fleet-wide.
In-flight rewritten to lead with the two jobs the operator named for the next
session -- drain the svos-dev message that has been unread since 00:52, then
stand up an STT service from nothing -- so a fresh context opens on the work
rather than on the history.
nh3-dev sits on the NH3 LAN and reaches every site through its own default
gateway; RouteAll was already false, so it never used the tunnel for routing.
Membership bought a 100.64.0.4 address nothing referenced -- grep across the
repo and ~/development found only docs and memory hits.
It also cost something concrete. A host running Tailscale installs
-A ts-input -s 100.64.0.0/10 ! -i tailscale0 -j DROP, and because the fleet's
subnet routers preserve source rather than masquerading RFC1918, a mesh client's
packet reached nh3-dev's ens18 still sourced 100.64.x and was dropped silently.
That is why nh3-dev.nh3.internal failed from the mesh while every NH3 host that
does not run Tailscale worked, and it needed a -d 10.100.10.50/32 -j MASQUERADE
exception on nh3-scale to paper over. Retiring the membership removed the
anti-spoof rule, so the exception went with it -- mesh-exit-masq.sh is back to
the two rules it had before yesterday.
Verified after: nh3-dev reachable at 10.100.10.50 from ESH, Anaheim, FV, Irvine
and NH3, and reaching all four sites plus the internet itself. fv-ml1
unaffected.
The mesh is now six nodes and every one has a job: three site routers,
vb-gateway, irv-ml1 (Irvine's own router, no separate scale node), and the
operator's MacBook Air. Nothing is enrolled just in case.
Operator's design, and a better one. Once the FV SNAT rules landed, fv-ml1's
mesh membership was redundant for routing and its only remaining value was as a
second way in. Keeping it enrolled bought a standing second door; joining on
demand buys the same recovery path without one.
normal tailscaled stopped + disabled; fleet reached via the gateway SNAT
fault nh3-dev / nh3-docker unreachable while the WAN is up
action start tailscaled + tailscale up -> reachable at its 100.64.x address
fv-ml1 is now off the mesh and its node record deleted. Verified it still
reaches NH3, ESH, Anaheim, Irvine and the internet on the SNAT path alone, then
the break-glass fired on cue (counted 1..4, joined at 5 as 100.64.0.10),
answered ping and ssh from nh3-dev, and was closed again cleanly.
No auto-leave, deliberately: once open the door stays open until a human runs
systemctl disable --now tailscaled. A watchdog that re-closes on recovery flaps,
and a flapping recovery path is down exactly when someone finally looks. It also
skips entirely when already on the mesh, which is what makes it idempotent after
firing.
The question exposed a hole worth more than the redesign. The stored rejoin key
was one of the 2026-09-12 FV cutover keys, expiring 2026-09-19 -- a break-glass
credential that dies in four days and fails silently at the only moment it
matters. Replaced with a dedicated 1-year reusable key (headscale ID 8, expires
2027-09-15), vaulted as fv-ml1/headscale-breakglass-key, root:600 on the host.
That also closes the standing self-join risk rather than trading it: the two
stale reusable keys (IDs 5, 6) are expired, so the mesh now has exactly one live
reusable key -- purpose-built, on a host we control -- instead of two orphans
nobody owned.
Rejoin uses --accept-routes=false and the reason is in the script: on 2026-09-14
tailscale up --accept-routes on this box accepted its OWN subnet from the
gateway and black-holed it. That happened with a human watching; here it runs
unattended, during an incident, on a box already in trouble.
Session captured: the FV outbound-NAT root cause and its diagnostic signature,
the fv-ml1 dead man's switch, fleet identity/group/path conventions and the
root:docker normalization, nh3-dev's ts-input reachability fix, ESPHome
modernisation and the kb KB-search tool, and the Hermes bearer rotation
release. Six new detail files.
Tried-and-abandoned gains three: probing OPNsense endpoints by POSTing at them
(which rebooted the FV firewall), advertising a /32 from nh3-dev, and the
nh3-scale remote-site masquerade rules that fired but were not the fix.
Housekeeping: 8 Recent-decisions entries archived to archival-memory.md, and 21
oversized inline entries split into detail files per the two-tier rule -- they
had been sitting fully inline in the index, which is what the split exists to
prevent. Two pointers to a detail file archived this run were repointed at
archival-memory.md.
The index is 389 lines, still over the ~300 soft cap. The archival guards stop
it there: only 4 further entries are old enough to move and every one carries an
open deferred-work pointer. An over-cap file that keeps live decisions beats a
scannable one that lost a deferred call.
All four outbound-NAT rules on the FV gateway now match source
10.251.50.0/24 instead of fv-ml1's single address, so a second host at FV
works on arrival rather than reproducing a failure whose symptoms point at
routing rather than NAT.
Anaheim got a /24 rule of its own through the API. The 2026-09-13 ANA rule was
written with write_config and is invisible to source_nat/search_rule, so
leaving it as the only ANA coverage would have kept one destination on a
different code path from the other three. The legacy /32 rule is now redundant
but harmless -- it NATs identically and first-match wins -- and is noted in the
runbook for deletion from the UI, since it is the one rule the API cannot see.
Descriptions rewritten to name the real scope. Three of them said "fv-ml1 to X"
while covering the whole subnet, and a description that understates a rule's
reach is the same trap as the Anaheim-only scope that caused this.
Verified after: fv-ml1 reaches NH3, nh3-dev, ESH, Anaheim, Irvine, the mesh and
the internet; nh3-dev, esh-docker-vm and ana-docker all reach FV and each
other; the FV BMC remains reachable inbound. Pre-change config backup taken.
Also records that 10.251.250.0/24 (BMC/management) is deliberately NOT covered
-- inbound reachability is what out-of-band recovery needs, but a management
host originating traffic to another site would hit this same wall.
FV could not reach any site but Anaheim. The cause was a single outbound-NAT
rule on the FV gateway, added 2026-09-13 and scoped to Anaheim only --
docs/runbooks/fv-to-ana-nat.md says so in as many words: "Other remote sites
remain outside this fix's scope." Three mirrors added, same interface and
source, only the destination differing: 10.100.0.0/16, 10.0.0.0/16 and
10.6.110.0/24.
After: fv-ml1 reaches NH3, ESH, Anaheim, Irvine, the mesh and the internet.
Regression sweep clean across nh3-dev, nh3-docker and esh-docker-vm.
The runbook now records what the failure looks like, because it presents as a
routing or Tailscale fault and is neither. fv-ml1 reached mesh addresses
perfectly and LAN addresses not at all; the FV firewall log showed the outbound
passing with src=10.251.50.54 and no reply returning; temporary counting rules
proved nh3-scale received 5 packets and sent 4 replies; both peers' AllowedIPs
were correct. The discriminator that settles it is that every other site pair
works -- nh3-docker to esh/ana/FV and esh-docker-vm to FV all succeed -- so a
general subnet-to-subnet limitation is ruled out and only outbound SNAT is
left.
Also reverts the remote-site MASQUERADE rules added to nh3-scale earlier on the
asymmetric-return theory. They fired but were not the fix, so they are removed
rather than left to accumulate as NAT that achieves nothing.
Applied via source_nat/add_rule + apply with a pre-change config backup taken
first. Source scope is still fv-ml1's /32, so a second FV host will hit this
again -- flagged in the runbook.
WATCHDOG (done, proven). fv-mesh-watchdog probes two independent anchors every
minute and, after 5 consecutive failures, puts Tailscale back to known-good:
accept-routes off, re-up against headscale with a stored key. It touches
nothing else — a watchdog with a wide remit is a second way to lose the box.
Two anchors that cannot share a failure mode: a plain-internet one and a
mesh-only one. If BOTH fail the site uplink is down, Tailscale cannot fix that,
and it deliberately does nothing — thrashing tailscaled during an ISP outage
turns a wait into an incident. Disable file at /etc/fv-watchdog.disable for
planned work.
Proven by positive control, not assumed: counter incremented 1..4 without
acting, fired the restore at 5 (tailscale up ran, tailscaled restarted), and
reset to 0 once the real anchor returned. fv-ml1 stayed reachable throughout.
This exists because a on fv-ml1 black-holed it
from its own LAN earlier the same day: it accepted 10.251.0.0/16 from the
gateway — its OWN subnet — and routed the local network through the tunnel.
FV CROSS-SITE ROUTING (partial). Two changes landed, the path is still broken:
1. acceptSubnetRoutes 0 -> 1 on the FV gateway's tailscale plugin, via
settings/set + service/reconfigure (the documented apply, not a reboot).
The GATEWAY now has 10.0/16, 10.100/16 and 10.250/16 in its routing table
and reaches NH3 and ESH itself. It could not before.
2. Remote-site MASQUERADE rules on nh3-scale. The existing jump matched only
-s 100.64.0.0/10, so traffic from another site's LAN never entered
MESH-EXIT and kept its original source; an NH3 host then replied via its
own LAN router instead of back through nh3-scale, making the path
asymmetric. The rule is confirmed firing (counter increments on FV
traffic) but does not complete the path.
Still failing: fv-ml1 -> NH3/ESH LAN addresses. Mesh addresses work perfectly
from fv-ml1 (100.64.0.1, 100.64.0.4), Anaheim works over the metro link, and
the FV firewall log shows the outbound passing on tailscale0 with
src=10.251.50.54 and no reply ever returning. The remaining gap is forwarded
FV-LAN traffic specifically, not the gateway's own.
Full regression sweep clean: nh3-dev, ana-docker and esh-docker-vm all reach
all four sites plus the internet.
