Rehome run 3c from ana-ml2 to pfi-gx10 unchanged: same corpus, base,
recipe and hyperparameters, different host. Slower (~13.3 h vs ~2.5 h)
and correct — an Anaheim breaker trip costs a 40-minute drive each way
and 13 hosts down, three of them SureFire client machines, while the
GX10 is a ~240 W appliance at NH3 that can take nothing else down.
Verified rather than assumed, because ana-ml2 ran transformers 5.15.1
on x86-64 and this box runs 5.16.1 on aarch64 — the silent
backend-delta class that has already voided conclusions here:
- both 49 GB base shards sha256-match ana-ml2's (size equality is a
weaker claim and was already true)
- a full encode was run into a throwaway dir and the encoded corpus
compared byte-for-byte: 197,360,233 B, sha256 c08bb1fe2ecb0be3,
identical. Every aggregate matched too. That verified artifact is
what the run will train on — it is seeded into run-03c/encode-cache
- the harness's own suite: 122 passed on aarch64
- the config generator asserts key-by-key that no non-path value
differs from run-03c.json
The encode-cache filename differs by design (base_model_path is part of
the key) — an input hash, not an output hash. Documented so it is not
misread as drift, or "fixed" by faking /tank on this box.
Corpus is copied to local NVMe; the box mounts no NFS. nh3-nas is now on
the same subnet, which makes mounting it tempting and still wrong under
a 13 h unattended run.
The launcher refuses on a live pidfile rather than a pgrep: `pgrep -f
erp_sft_harness` invoked over ssh matches the invoking shell's own argv.
That self-match cost a shell during staging.
Not launched. 13.3 h is the operator's call.
The probe finished. Median is 79.36 s/it across ten timed steps with a
min/max of 79.30 to 79.45, and peak memory is 75.1 of 121.6 GiB by
PyTorch's own max_memory_allocated -- 46 GiB spare rather than the 35 I
estimated from a live free reading, which was counting fragmentation and
the resident model rather than the allocation high-water mark.
Resolved attention backend recorded as flex_attention, read off the loaded
model rather than trusted from the request, which is the check I got wrong
the first time.
Rewrote the in-flight section to reflect that nothing is running and the
operator stood the session down. The GX10 work is recorded as what it was
asked to be: a baseline for the box and a check that the tooling loads,
with the run-3c port scoped but explicitly declined.
Added index lines for four decisions that had detail files but no pointer:
the GX10 baseline at 79.35 s/it, the costing error the operator overruled,
the althing four-surface deploy finding, and the irv-ml1 GPU resident map.
Auto-archival fired at the soft cap and moved 17 entries dated on or
before 2026-08-18 to archival-memory.md, holding back 4 that carry open
deferred-work pointers. The index went from 410 lines to 296, mostly by
rewriting in-flight rather than by archiving -- the dated log was not what
made it long.
Operator clarified the purpose, so the record now leads with it: this was
a baseline for the box and a check that the tooling loads, not a decision
about where run 3c runs. The placement reasoning stays because it is
sound, but it is marked as a byproduct rather than the deliverable.
Two things were actually delivered. The box trains: aarch64 and sm_121
run torch 2.14.0+cu130 with transformers, accelerate, peft, trl, datasets,
safetensors and bitsandbytes, plus the harness's own flex_attention
backend and chunked-loss path, and nothing beyond python3-dev was needed.
And the baseline is 79.35 s/it median across seven timed steps with a
0.19% spread.
Also recorded the port scope without executing it, so nobody re-derives
it: about 2.5 GB of data, a venv rebuild on aarch64, no encode cache worth
moving since the encode runs in 14 seconds, and copy the corpus rather
than mounting NFS on a desk box that will be unattended for hours.
The operator overruled my ana-ml2 recommendation and was right. I had step
times in hand, so I priced a breaker trip as eleven minutes of lost
training. That is the recompute cost and it is the cheapest component of
the loss.
A breaker trip at Anaheim is a forty-minute drive each way on the
operator's time, whenever he happens to notice, with thirteen hosts dark
until he arrives -- including the hypervisor most of them run on, the
fleet's primary backup server, and three SureFire client machines that are
a customer's production hosts under a hosting agreement.
So save_steps 100 to 50 caps the recompute, not the outage, and it was
never the mitigation I claimed. Thirteen hours unattended on a desk in NH3
beats two and a half hours that can put a client's hosts dark, especially
when nothing is waiting on this run.
Recorded the general form at length because it is the transferable part:
when recommending between options, check whether you priced the failure
mode in whatever units you happened to be measuring. A metric in hand will
volunteer itself as the unit of risk.
Also measured and dismissed the obvious third option: the RTX PRO 6000s
have a 250 W floor against a 300 W default, so capping both saves 100 W on
a box drawing about a kilowatt. Not enough to matter, and it costs
throughput to buy.
The GX10 runs run 3c at about 79.3 s/it with 35 GB of headroom, which puts
604 steps at 13.3 hours against ana-ml2's 2.2 to 2.7. Six times slower
where raw compute predicts 2.7, which points at memory bandwidth rather
than FLOPs -- recorded as a hypothesis, since confirming it needs a
bandwidth-bound microbenchmark nobody has run.
That reverses the standing plan. Moving run 3c here was framed as the
power answer, but the run did not die because ana-ml2 is unreliable. It
died because save_steps was 100 and the breaker tripped at step 80, so no
checkpoint existed. save_steps is now 50, which caps a power event at
about eleven minutes. Trading 2.5 hours for 13.3 buys insurance against a
risk already engineered out.
Also records the five launch failures and their causes, and the one that
matters most: the attention-backend trap was present and I first declared
it absent. I checked whether flash-attn was installed, which is the wrong
discriminator; the harness sets flex_attention explicitly in code. Absence
of an alternative is not evidence of the default. The probe now reads the
resolved backend back off the loaded model, and flex_attention does
compile and run on sm_121.
A version number cannot tell you what a stale plugin cost. 0.0.1 and
0.1.1 differ by two hooks and a script, so the runbook now carries a
check that compares hook lists across cached versions and looks for
pane-route.sh directly.
Also records why this hid for five days, which is the more transferable
half. A missing deploy surface does not present as an error -- it presents
as "the migration needs manual work", and there was a ready explanation
for that, because four of five seats were non-Claude and genuinely did
need hand-holding. The seat that falsified the story was our own: a Claude
Code seat that should have self-declared and did not, and it looked
exactly like the other four. Nobody asked why the automatic path had not
fired on the one seat it was built for.
So: when a migration needs manual intervention, verify the automatic path
was actually deployed before concluding it does not apply to your case.
Deployed 3.2.4 and closed the fourth deploy surface. The plugin cache
moved 0.0.1 to 0.1.1 via `claude plugin update althing`, which means the
step I had escalated to the operator was mine to do. Refusing to
hand-edit installed_plugins.json was right; concluding no supported path
existed was an untested assumption, and `claude plugin` has install,
update, uninstall, list, details, validate and marketplace subcommands.
Recording the pattern once rather than four separate lessons: four times
tonight I reported a proxy or an assumption as the fact itself. sudo -n -v
for NOPASSWD, command -v nvcc for the toolkit, a lock file's pid for a
flock, and "no CLI path exists" for a CLI I never ran. Each was cheap to
test and expensive to assert.
Also ran the audit forseti's 3.2.4 makes possible, since a seat could have
been silently pull-only since 3.1.2 with every failure rendering as
silence. Nine of ten seats with a live waiter report push. regin-smithy-dev
holds a live waiter and the post office has it pull-only -- but regin
deliberately released their pane route earlier tonight, so release-then-arm
ordering explains the same observation with no bug involved. Not
distinguishable from outside, so it went to regin as a question rather
than to forseti as a confirmed instance.
forseti measured my stale-lock claim and it is false. I said a lock file
holding a dead pid would make the next althing-listen exit 3 and turn a
reap into a permanent monitoring outage that reports healthy. The gate is
flock -n on an open fd, which the kernel releases when the holder dies, so
a lock left by a reaped listener is inert and exit 3 only fires against a
live holder. The pid in the file is read by --stop alone.
I reasoned from the artifact's contents when the behaviour is set by the
locking mechanism, and put the consequence in durable memory without
testing it. forseti tested before writing code. That is the third time
tonight I reported a proxy as the thing itself, after sudo -n -v for
NOPASSWD and command -v nvcc for the toolkit.
Deployed 3.2.3, which makes althing-listen refuse on a pane seat with its
own exit code rather than silently demoting it.
And found the real shape of the plugin gap, which is worse than the stale
document forseti and I were both discussing. Nothing syncs the repo's
plugin directory into the marketplace directory, so it was frozen at Aug
28 with only the UserPromptSubmit hook -- no SessionStart, no SessionEnd,
no pane-route.sh at all. That means "CC seats re-declare automatically at
their next SessionStart" has never been true on this box, which is why
every seat including our own needed a hand-fed declare. Source is fixed
and bumped to 0.1.1; refreshing the plugin cache needs a /plugin update
from the operator, and I deliberately did not hand-edit Claude Code's own
plugin bookkeeping to force it.
The comparison number nobody had written down: ana-ml2's real run-3c step
times, pulled out of run-03c.log before the breaker killed it. About 10.8
to 15.8 s/it over the first 24 steps, so 604 steps lands at roughly 2.2
to 2.7 hours. Anything under about 45 s/it on the GX10 makes it an
overnight run.
Also records the exact geometry from run-03c.json and a real
adapter_config.json, so the probe measures the shape that actually ran
rather than an approximation of it.
Checked the backend-delta trap the playbook warns about before running
anything rather than after: flash-attn is installed on neither box, so
both fall back to sdpa. Library versions do differ -- torch 2.13.0 versus
2.14.0, transformers 5.15.1 versus 5.16.1 -- and that is recorded rather
than assumed harmless. The probe reads the resolved attention
implementation back off the loaded model instead of trusting the request.
The probe discards its first two steps as warmup, which is not optional on
this box: an unwarmed benchmark here already read 27 TFLOP/s when the true
figure was 93, because it was timing the PTX JIT.
`sudo -v` refreshes the auth timestamp, and a NOPASSWD-only rule creates
no timestamp to refresh, so on sudo >= 1.9.15 `sudo -n -v` returns
non-zero while every real command runs passwordless. Measured:
pfi-gx10 sudo 1.9.15p5 sudo -n -v rc=1 sudo -n true rc=0
nh3-docker sudo 1.9.13p3 sudo -n -v rc=0 sudo -n true rc=0
ana-docker sudo 1.9.13p3 sudo -n -v rc=0 sudo -n true rc=0
irv-ml1 sudo 1.9.13p3 sudo -n -v rc=0 sudo -n true rc=0
Only pfi-gx10 is new enough to hit it today, but every host does as it
moves past 1.9.13, and the failure mode is bad: elway prompts for a
password on a host with working NOPASSWD sudo, which in a
non-interactive run is an EOFError partway through a playbook.
The same probe in my own notes cost this session directly. gx10 looked
like a fleet exception with no NOPASSWD sudo when it had it from account
creation, and the operator was asked for a password that was never
needed. Corrected in auto-memory too.
Also lands the gx10 privileged outfit playbook, now green at 5/5:
NOPASSWD sudo, nvcc, docker group, a CUDA container seeing the GB10, and
the userspace torch stack still working afterward.
Ruling on the architecture question: bare metal, not Proxmox. Proxmox VE
has no aarch64 build, and more fundamentally the GB10's GPU sits on an
on-package root complex cache-coherent with the CPU over NVLink-C2C,
sharing the same LPDDR5X. Passing it to a guest would mean partitioning
the unified memory that is the entire reason for the box. The fleet's
other GPU hosts are bare metal for the same class of reason.
Installed uv and a venv with torch 2.14.0+cu130 plus the full training
stack, and every one of transformers, accelerate, peft, trl, datasets,
safetensors, huggingface_hub and bitsandbytes imports clean on aarch64.
The per-arch unknowns warning did not materialise for any of them.
CUDA works: sm_121, 121.6 GiB addressable, about 93 TFLOP/s dense bf16
with tensor cores confirmed engaged by the bf16-to-fp32 ratio. That is
A6000-class throughput with two and a half times the memory, so capacity
rather than speed is what this box buys.
Two warnings worth keeping. sm_121 is not in torch's compiled arch list,
so everything runs by PTX JIT from sm_120: first use of every kernel pays
a compile, and any library shipping cubins without PTX will fail outright.
And an unwarmed benchmark read 27 TFLOP/s because it was timing that JIT,
which nearly became a phantom report that tensor cores were broken -- the
playbook's section 4 shape exactly, a run that completes and reports
plausible numbers and is wrong.
The privileged half is blocked: infra-ops has no NOPASSWD sudo on this
box, unlike the rest of the fleet, and no credential is vaulted. That
gates nvcc, the container toolkit and the docker group, but not the
run-3c throughput probe.
Probed the box read-only. Alive and idle at 11h48m uptime, 118 of 121 GB
memory free, 822 GB disk free, and completely unchanged since onboarding:
no torch, no nvcc, no uv, and infra-ops is not in the docker group.
The useful finding is a negative one. I assumed the temporary Wi-Fi would
gate getting a 49 GB base model onto the box and it does not. The link is
Wi-Fi 7 on 6 GHz at 2401.9 Mbit/s with a -48 dBm signal, and a measured
300 MB transfer ran at 67 MB/s over SSH, which puts the full base at
about twelve minutes. SSH's cipher is the limiter there, not the radio.
So the throughput probe can run from the desk today and racking is worth
doing for permanence rather than as a blocker.
Also recorded that nvidia-smi reporting FB Memory and BAR1 as N/A is
correct for GB10 rather than a driver fault, since the Grace Blackwell
superchip shares unified LPDDR5X between CPU and GPU and has no discrete
VRAM figure to report.
The /althing:monitor slash command is a separate artifact from the
canonical skill and sync_skill.sh does not touch it. It sits at plugin
version 0.0.1 with pre-3.2.0 text and zero mentions of pane routes, while
the canonical skill it should mirror is at 3.2.2.
That makes it active harm rather than stale documentation. The canonical
precedence rule is that a live waiter wins over a pane entry, so an agent
on a healthy pane route who follows the command verbatim demotes itself
back onto the FIFO path the harness reaps -- the path that died twice on
this seat tonight. The command cannot warn about it because it predates
the problem, and every Claude Code seat reaches for the slash command
first because it is the discoverable surface.
Declined to arm on this seat and left the route intact. Reported to
forseti with a recommendation that althing-listen refuse to arm when a
pane route exists for the handle, since a binary enforcing the documented
precedence beats a doc that relies on a reader noticing.
Also cleared a stale wake-listener lock holding a dead pid, and recorded
why it matters: the next althing-listen seeing it exits 3, whose
documented response is do not drain and do not re-arm. A stale lock turns
a reap into a permanent monitoring outage that reports itself as healthy.
Checked the disk rather than waiting on comfy-dev. Both builds are there,
pulled a minute apart on Aug 23: a 26 GB int8 and a 15 GB nvfp4-awq.
I had asked whether their nvfp4 pin was set under a Blackwell assumption,
since Ada has no native nvfp4, which would make the int8 file the right
one on the new box. It cannot be. They pinned it on irv-ml1's A6000,
which is Ampere sm_86 and has neither native nvfp4 nor native fp8. Ada
sm_89 supports a strict superset, so a pin that was correct on the weaker
card cannot be invalidated by moving to the stronger one. The migration is
incapable of breaking it.
The pin is about VRAM, not architecture. Eleven gigabytes on a 48 GB card
that also holds a DiT and two VAEs decides whether a graph runs, and a
text encoder runs once per prompt rather than once per diffusion step, so
its throughput matters far less than the DiT's. That also explains why
this pin went the opposite way from their other one without either being
inconsistent. The RTX 6000 Ada is also 48 GB, so nothing relaxes.
Reclassified the 26 GB int8 from orphan to spare: with the extra drives
the destination lands near 14% full, so disk stops being the constraint
and the pin-rot argument says keep it. Question withdrawn to comfy-dev.
Four of the five items I raised are closed and tagged. The one that
matters most: --discover-pid matched comm == "claude", which means kimi,
grok, codex and pi would each have walked to the multiplexer and refused.
Four of five pane seats could never have used it. It now matches the
pane's own command, which zellij already reports and guard 1 already
compares against, so discovery and the guard read one string.
Recording a second miss of my own alongside it. I handed all four seats
explicit measured pids because I suspected the ancestry walk was broken,
then reported the suspicion as an open question rather than spending the
same twenty seconds to settle it, with four live non-Claude seats in
front of me. That pairs with the earlier miss in the opposite direction:
asserting an open risk on something the author had already measured. Same
root -- having the means to settle a question and reporting it as open
instead.
Also keeping forseti's two dead ends as negative results, because they
are the obvious things to propose next and both fail: locating a TUI's
input box in a screen dump needs per-TUI parsing, and diffing two dumps
to detect typing refuses every poke forever, because status bars carry
live token counts and clocks so consecutive dumps differ on an idle pane.
The kimi/pi coverage gap is deliberately unfixed and now sits with the
operator, with a recommendation to leave it per-seat.
All four seats answered. Delivery is now verified on four TUI families and
forseti's measured idle columns held exactly, so nobody had to guess.
The two seats guard 4 cannot cover made opposite calls on the same facts
and both are right. regin-smithy-dev released to pull-only because the
operator composes in that pane routinely, so the exposure is continuous.
bil-smithy-dev kept its route because that pane is poke-driven, making the
collision window narrow, and because pull-only had already cost them a
notice that sat unread for days. The deciding variable is who composes in
the pane and why, not risk appetite -- a flat rule either way would have
been wrong for one of them.
regin also supplied the only real path to closing the hole: pi and kimi
report no cursor because their input line is not an empty-prompt-at-idle,
so a moment-check reading pane content rather than cursor column would
cover them. Column is a proxy; an empty input line is the actual
predicate. Relayed to forseti as the lead item.
And bil corrected something upstream: the Aug 28 probes proved delivery
against non-Claude TUIs but never exercised the collision case, because
nobody was typing during them. Two different questions, one body of
evidence, only one of them answered by it -- which means the earlier
retraction of the non-Claude risk flag was right about delivery and
silent about stapling.
Note for the operator: regin-smithy-dev is pull-only as of 22:42 and will
not be poked until it declares again.
3.2.0 wrote its pokes into pane input lines and pressed Enter, so anyone
mid-sentence had their half-written message submitted with the herald's
line stapled on. It hit the operator within an hour of this evening's
deploy. 3.2.1 adds a fourth guard that pins the pane's idle cursor column
and stays silent when the live column has moved.
Deployed all three steps at 22:40 and re-declared this seat, which pinned
idle_cursor=3 as expected for a claude TUI.
The finding worth keeping is the hole the fix leaves. forseti's own
measurements say kimi and pi report no cursor at all, which means
bil-smithy-dev and regin-smithy-dev can never acquire guard 4 no matter
what they run. Two of the five pane seats on this box stay permanently
exposed to the bug 3.2.1 fixes, so the sentence "3.2.1 fixes the
write-into-a-typing-pane bug" is only true where the cursor is legible.
All four seats were told, differentiated: a pre-filled re-declare and the
expected column for the two that can be guarded, and the honest version
plus the release-to-pull-only option for the two that cannot.
Also keeping forseti's post-mortem line, because it generalises: three
guards that all answer "is this the right pane" and none that asks
whether it is a good moment are one check wearing three hats.
All four notified seats re-declared within about twelve minutes and the
log went quiet. Five of five pane routes now carry the guard fields, and
delivery is confirmed on a claude seat, a pi seat and a grok seat.
Two findings survive the close-out. The herald's exclusion reason is
false for the migration case -- every declaring process was alive and
four days old with no pid wrap, and the real cause is simply that the
route predates the fields the guard needs. And the uv trap stands as the
thing most likely to bite the next person.
The third is mine. I raised non-Claude pane delivery with forseti as an
open risk on their release when forseti had personally measured it days
earlier, on the exact seats in question, and the resulting matrix is what
characterised the settle bug they fixed. The error was not caution, it
was calling something open without checking whether it was already
settled, with the peers who knew right in front of me. Recorded because
"I don't know" and "this is an open risk" are different claims and I made
the second when only the first was true.
Still open with forseti: the uv --force runbook fix, an exclusion-message
third branch, --discover-pid against a non-Claude process tree, the
one-tick latency note, and status not being durable evidence.
Operator directed that the four affected seats be told directly. Measured
their state before writing, which turned up two things worth more than
the notification itself.
The herald logs each exclusion as "the process that declared this route
is gone, or its pid was reused by something that started at a different
time." Neither is true for any of the four. Each declaring process
started minutes before its route was written and is still running four
days later, and pid_max is 4194304 against a current 2.86M so the counter
has not wrapped. The real cause is a third one the message never offers:
the route predates the guard fields, so identity cannot be verified. The
behaviour is right and the explanation is wrong, and it would send anyone
debugging it hunting a dead agent that is alive.
Separately, all four seats run non-Claude CLIs -- kimi, grok, codex and
pi -- while the pane poke is built around typing into a Claude Code pane.
Whether --discover-pid walks a non-Claude process tree, and what a poke
does to a non-Claude TUI, are both unverified. Each agent was given their
measured pid to sidestep the first, told plainly about the second, and
offered the choice between re-declaring as a test or staying pull-only.
Both findings raised with forseti.
The waiter died a second time, within minutes of being armed, so this
seat stopped re-arming and declared a pane route instead. That is exactly
what 3.2.0 shipped for.
- althing-route declare --discover-pid walks the ancestry to the
long-lived claude process rather than the ephemeral bash that invoked
it. Passing --pid $$ would bind the route to a shell that dies with the
tool call.
- Recorded the sharper form of the failure: the waiter does not just die,
it dies after confirming it is up. Both waiters reported push and
reachable immediately after arming. So a green postbox status is not
durable evidence of monitoring, and the reap is not confined to the
pane seats that were migrated -- this seat is a fifo waiter and was hit
twice.
Both consequences raised with forseti on the deploy thread, along with a
note that reachable is a report rather than a delivered poke.
forseti requested the deploy, operator-approved and tagged at c4ede0f.
All three steps landed on nh3-dev and verified: force reinstall to 3.2.0
with seven binaries, herald restart, skill sync.
The durable lesson is the trap in step 1. `uv tool install .` matches on
the source spec rather than its contents, so on a box that already had
the tool installed from that path it prints "already installed" and exits
0 having done nothing. Following the runbook literally would have left
the new binary absent with every command reporting success. Always use
--force when reinstalling from a local path.
Also recorded: the pane-route migration revoked exactly four routes,
verified by splitting on channel= before the restart rather than by
auditing fields (all twelve route files lack the new fields, so a field
audit over-counts). The four affected agents were deliberately not
notified, per the standing rule against unsolicited fleet broadcast, and
that is surfaced to the operator instead.
And this closes an open question from earlier today: the waiter that died
with status "killed" was CC 2.1.257 reaping detached tasks, which is the
premise 3.2.0 exists to address.
Operator freed ComfyUI's VRAM directly, so tts-dev is unblocked and the
window request is withdrawn with comfy-dev.
- Verified it was a model unload, not a stop: comfyui still up 8 days,
same pid, HTTP 200, 18,500 -> 612 MiB. Told comfy-dev explicitly so a
VRAM drop is not misread as a restart of their service.
- The resulting 43.8 GB free is a snapshot, not a floor. ComfyUI is live
and reloads ~18.5 GB on the next render, which puts the real floor at
~25.3 GB against FireRedAudio's ~26 GB requirement. The coordination
shrank from "stop ComfyUI" to "don't render during the bench" rather
than disappearing. Flagged to both; not volunteered on comfy-dev's
behalf.
- Withdrew my caching-allocator hypothesis for the dots-tts VRAM. tts-dev
identified it as their prompt-feature cache, capped at 32 entries on
2026-08-14 after two production incidents. A named mechanism with an
incident history beats a plausible story, and the useful finding is
that 14.43 GB sits inside a cap they deliberately chose.
Read-only probes; nothing on the box was changed.
Memory-only; no version bump per the SemVer SKIP list.
tts-dev asked for an A6000 window for an approved TTS bench and flagged a
3090 VRAM delta. Probed the box and mapped PID to container rather than
taking the reported figures.
- The 18.5 GB process they attributed to the 3090 is comfyui, on the
A6000. And it is 18.5 GB rather than the ~11.8 GB they budgeted, so
stopping it gives ~44.4 GB free, not the tight margin they expected.
- Their "~4 GB unaccounted" on the 3090 is two things: parakeet is a
third tenant the doc figure never counted, and dots-tts alone is
holding 14,430 MiB against a burn-in figure of ~6 GB. The second is
the larger finding and it is theirs to act on; handed over with a
caching-allocator hypothesis and a one-restart discriminating test.
- Restated the GPU ordering foot-gun: device_ids ["1"] is the A6000 in a
container, but a bare native CUDA_VISIBLE_DEVICES=1 gets the 3090.
Window not granted unilaterally — comfyui is comfy-dev's and they are
mid-migration, so the request went to them directly and infra-ops relays.
Ruled that the bench runs as a plain container under lkraven rather than
under /opt/docker/compose/, which is for deployed stacks and would leave
a canonical entry reporting as drift until deleted.
Read-only probes; nothing on the box was changed.
Memory-only; no version bump per the SemVer SKIP list.
Operator asked why not move all 768 GB across. It does not fit the
board's shape: the R640 has 24 slots at 6 channels/socket x 2 DPC, the
R750xa has 16 at 8 channels/socket x 1 DPC.
768 GB is either 24x 32 GB (more DIMMs than slots) or 12x 64 GB (fits,
but populates 6 of 8 channels per socket and gives up ~25% of memory
bandwidth). The board wants 16 identical DIMMs. So the targets are
512 GB if they are 32s, or 1 TB if they are 64s — taking 12 from one
spare and 4 from the other. In the 64 GB case the answer beats the
question.
Also recorded: beyond ~512 GB the return is marginal for this workload,
so take 1 TB because it is free rather than because it is needed; 64 GB
LRDIMMs run ~50 W hotter in a chassis whose high-performance fans are
unaccounted for on the invoice; and DIMM slot count now needs to be on
the iDRAC pull, since the 16-slot figure is inferred from the factory
CSV and is load-bearing for a 512-vs-1024 decision.
Memory-only; no version bump per the SemVer SKIP list.
Operator asked whether 512 GB justifies a ramfs for hot models, then
self-corrected toward ARC with a 128 GB cap.
- No ramfs/tmpfs tier. ARC is the same cache done adaptively: no curated
hot-list to rot, no boot-time copy-in, and the memory comes back under
pressure. Neither tier beats the host-to-VRAM PCIe hop anyway, so the
warm-load time is identical.
- 128 GB is below the OpenZFS Linux default of 50% of RAM, so doing
nothing already gives 256 GB. Recommend ~320 GB, not past ~75%.
- Recorded the one honest argument for tmpfs: safetensors mmap gets
double-buffered on ZFS-on-Linux, so a checkpoint can cost ~2x. Sized
for, not architected around.
- Flagged that this is not the idle-VRAM-is-reserved case: arc_max is a
ceiling on an elastic cache, not a preallocation.
- recordsize=1M cannot be won through zfs send, since recv reproduces the
source's block structure. Not worth losing incremental send over; the
128K cost on flash is metadata overhead, not throughput.
Memory-only; no version bump per the SemVer SKIP list.
Operator has 2x Dell R640 at 768 GB each and asked whether the memory is
interchangeable with the R750xa. Both are DDR4 RDIMM platforms and Dell
does not vendor-lock DIMMs, so the answer is very likely yes.
- 16 slots in the R750xa x 32 GB = 512 GB, double the factory spec, and
it deletes the 8x M04W6 purchase.
- Gating question is RDIMM vs LRDIMM. 24x 32 GB 2Rx4 RDIMM is the safe
and most likely case; 12x 64 GB LRDIMM needs Ice Lake support checked.
- Cleanest harvest is to strip one R640 entirely and leave the other
whole, rather than half-emptying both into unbalanced populations.
Separately, reading the factory CSV to answer this surfaced a gap in the
diff table: the reseller also swapped 2x Xeon Platinum 8362 (32C/64T,
265 W, DDR4-3200) for 2x Xeon Silver 4314 (16C/32T, 135 W, DDR4-2666).
The Silvers were recorded under "As bought" but never diffed, so the swap
went unremarked. Two consequences: the box cannot use the 3200 rating the
buy list was paying for, which makes 2666 R640 DIMMs a free lunch; and
the CPUs draw 260 W less, which the existing ~1,020 W power figure
already assumed correctly.
Memory-only; no version bump per the SemVer SKIP list.
Six drives fills all eight bays, which turns a capacity top-up into a
one-shot build decision. Recorded because the reasoning survives whatever
he picks:
- raidz2 over mirrors. Workload is large sequential reads of safetensors,
ARC fronts it, SSD resilver has no seek penalty, and "expand two at a
time" is meaningless once every bay is full. raidz2 survives any two
failures; 4x mirrors dies to an unlucky pair.
- Buy 8, not 6. A raidz vdev caps every member at the smallest, so the
two as-bought 1.92 TB drives would cap all eight and put two used
drives of unknown endurance inside the parity set.
- Drive size is now the permanent ceiling. SAS/SATA backplane, all bays
full, and the free-PCIe-slot inventory is still unpulled.
Runway table included with an explicit caveat that the growth rate is
projected off one acquisition batch, not measured.
Memory-only; no version bump per the SemVer SKIP list.
comfy-dev's disk-vs-catalog diff and a recount of my own figures both
landed on this thread. Two numbers were wrong and both were headed for
the operator's sizing conversation.
- My ~90% was a double-count. I read ALLOC 1.45T while their pull was
running and then added the full ~112 GB on top; most of it was already
in that reading. "Onboarded" is not "landed". Settled payload is
~1.47 TiB and the as-bought mirror lands at 84%, not 90%.
- comfy-dev's "pruning gets us nearer 45%" is the striped figure. On the
as-bought pair mirrored, deleting all ~215 GiB of unreferenced weights
still lands at 72%, with ~140 GiB of runway on a store that took on
~100 GiB in one day. The constraint is vdev layout, not payload — a
1.75 TiB pool stays 1.75 TiB whatever goes in it.
- So the prune audit and the drive purchase are independent decisions
and neither gates the cutover. Presenting them to the operator that
way rather than as a trade.
Also recorded: pool arithmetic (1.75 / 3.49 / 3.57 TiB), the mirror-vdev
smallest-member gotcha if the new drives get paired one-each with the
1.92s, comfy-dev's 34 GiB of uncatalogued LTX 2.5, and an open question
back to them on whether the H3 encoder's nvfp4 pin was set under a
Blackwell assumption that sm_89 does not satisfy.
Memory-only; no version bump per the SemVer SKIP list.
Measured irv-ml1's storetank against the R750xa's as-bought drives while
answering comfy-dev's "does the Ada box have ZFS?" question.
- storetank: 1.81 TiB pool, 1.45 TiB used, 80% CAP already, compression
off at compressratio 1.00x (safetensors incompressible — no win at
recv). comfy-dev's ~112 GB batch is landing into it now.
- The R750xa shipped 2x 1.92 TB SATA SSD; mirrored that is ~1.74 TiB,
smaller than the pool it receives from. Migration would arrive at
~90% full with no growth room.
- Buy list: +2x 2 TB SATA SSD (6 bays free, HBA355i has the ports) ->
two mirror vdevs striped, ~3.49 TiB at ~45%, redundancy intact.
- Retain vs reclaim irv-ml1's /storetank after cutover: RETAIN
recommended, surfaced to the operator.
Also corrects branch (b)'s recorded rationale. comfy-dev enumerated all
twelve running containers: only comfyui mounts /storetank, so (b) was
unavailable during the transition, not structurally. Right conclusion,
wrong reason — infra-ops reasoned about the box when the question was
about the mount.
Memory-only; no version bump per the SemVer SKIP list.
Dell R750xa JPJ1ZP3, 2x RTX 6000 Ada to be fitted, ComfyUI's new home at NH3. Diffing
Dell's factory CSV against the reseller invoice shows four downgrades: half the RAM, the
2400 W PSUs, and the GPU risers, cables and high-performance fans all absent.
Records the resolved GPU power chain, correcting my own first answer: the chassis' CPU
8-pin cabling is the right source type and NVIDIA 930-00030-1546-000 bridges it to the
card's 12VHPWR, so the PCIe-type RCCWC I first proposed is withdrawn. Also closes the NVMe
question — the backplane is SAS/SATA only — and notes that free PCIe slots may moot it.
Auto-archival fired at 308 lines; seven entries moved to archival-memory.md. The 250-line
target was not reached because the guards hold nearly everything else back as under 14 days
or carrying open deferred work.
Run 3c's new intended home is the GX10 rather than a power triage on ana-ml2: a ~240 W
appliance instead of the kilowatt-class box that tripped the breaker, and 121 GB unified
holds the 49 GB bf16 base comfortably where ana-ml2 was tight. The box is bare, so the
first move is a throughput probe rather than a harness port.
Also banked: the Ada migration settling on zfs send with branch (b) ruled out by irv-ml1
keeping its eight services; the Synapse 39-release upgrade with its one-way schema
migration, the appservice namespace opening and the admin API lockdown; the ratified room
alias convention; and a named failure class — a correct check aimed at the wrong object —
with six instances from one day across three sessions.
The in-flight section was a day stale: it still described run 3c as the
live subject on a box where nothing had moved. Rewritten around what is
actually true now -- v3 deployed fleet-wide, the post office relocated
to nh3-docker, sec serving on GPU0, run 3c still held on power.
Six new decision entries, three of which carry findings that outlive
their incident: the inbound half of the handle-resolution bug (a stale
ALTHING_HANDLE reads another agent's mailbox and reports it empty,
which is a second route into the failure v3 exists to prevent), the OOM
attribution to Claude Code sessions, and the operator's two explicit
belays recorded so a later session does not re-raise them as new.
Auto-archival fired at 301 lines and moved exactly one entry. Three
others were old enough and every one carries a still-open deferred
pointer -- the parked CI flip, muninn-gate's submit path, and the triton
backend deferred to the Ada refresh. Held back per the guards; an
over-cap file that keeps live decisions beats a scannable one that lost
them. The entry that did move had its deferred item closed today:
nh3-extdev's staged v2.1.2 wheel is moot now that the box runs 3.1.1.
Operator directive, and a standing goal: the bus belongs on the docker
host. The flag-day deployment put it on nh3-dev because the herald lives
there -- but the herald is the piece that must be host-local, and the
post office is explicitly the piece that is not.
nh3-dev was wrong on three counts. Our own server table calls it "not a
Docker-stack host". It has had three OOM events in fourteen days with
the interval halving, and the confirmed hog is Claude Code sessions at
5-18 GB, which is that box's actual job. And mem_limit protects the
fleet from the post office while doing nothing in the other direction:
oom_score_adj was 0, an ordinary kill candidate, on a box whose last
sweep took althing-herald and uvicorn. The new deployment sets
oom_score_adj=-500.
The compose is now version-controlled here as a normal stack rather than
living only in the althing repo's deploy dir.
## docker stop does not checkpoint the WAL
The database was 155 KB with a 4.1 MB write-ahead log, and every recent
message was in the log. A clean container stop left it untouched -- an
explicit PRAGMA wal_checkpoint(TRUNCATE) was required.
A docker cp of the .db alone would have produced a database that opens
cleanly, passes integrity_check, serves the full 73-handle roster, and
is missing the day's mail, with nothing raising an error. Row counts
were verified at source, in the staged copy, and after seeding, because
the count is the only thing that separates those two outcomes.
The old volume is left in place. Not a rollback path, which the operator
ruled out -- just not deleting the only other copy on the day of a move.
## Follow-up left open
The image has no registry push and moves by save/ssh/load, so a rebuild
means repeating that by hand. It should join the gitea registry pattern
the other stacks use.
Two operator-authorised changes on the same afternoon.
## althing v3 (U9b flag day, one-way, no rollback)
The post office replaced the v2 P2P bus on nh3-dev and nh3-extdev.
One container is the only stateful component; heralds are one per box
and dial out; waiters are one per session. Every v2 command was deleted
rather than deprecated, so a script calling althing-cli now fails loudly
instead of silently talking to nothing.
73 handles seeded from the v2 CLI, which is authoritative over the v2
database's 91 agent rows -- the extra 18 are superseded names, a typo,
an underscore variant, and two machine-qualified handles that v3 makes
a category error. Verified by set difference in both directions rather
than by counting; a peer's "72 rendered" was a line-count artifact.
Deleted 5,043 orphaned wake FIFOs. The reason there were five thousand
is that v2 named them per session with the PID and never reaped them;
v3 names them per handle, so the leak is bounded by construction. That
is a fix in v3, not a cleanup we performed.
nh3-extdev needed its own path: althing lives there as a system wheel
under /opt/uv-tools with entry points in /usr/local/bin, its daemons
were system units rather than user units, and uv is not on the login
user's PATH. Captured as a rerunnable playbook rather than shell
history.
The v2 database is left inert on disk. There is no import path and none
was improvised.
## sec onto GPU0
GPU1 carries the five resident fleet seats and had ~28 GB free against
the ~51 GB this seat reserves, so it could not start there at all. GPU0
has been idle since run 3c was stopped. The compose header, the GPU pin
default and the homepage label all carried the old card number and are
corrected together -- a label that names the wrong GPU is a record that
lies about where the work runs.
Both playbooks carry verify phases that assert effective state. Two of
those verifies failed on green deployments while I was writing them:
one used a Go template that collided with the runner's own {{ }}
substitution, one omitted --handle so it failed on identity rather than
reachability. Both are fixed with the reason recorded inline, because a
verify that reports FAILED on a working system trains you to ignore it.
forseti asked for journald kernel persistence plus sysstat, on the
premise that nh3-dev's three OOM events in 14 days left no evidence.
The premise was wrong. journald has been persistent all along: 15,068
kernel entries in the 82-day previous boot and 351 OOM records across
retained boots, full task tables included. `journalctl -b -1 -k`
returned one entry because it ran as a user in neither adm nor
systemd-journal, and journalctl shows only your own messages in that
case. The same artifact produced the "journal stops at 05:36:08 with no
shutdown sequence" claim -- the true boot -1 end is 05:47:04 with OOM
kills logged at 05:38, 05:40 and 05:42.
So the fix for "no evidence" is a group membership, not a logging
change: usermod -aG adm lkraven, which is the group Debian's journald
ACL names explicitly.
With the journal readable the attribution is already in it. The
versioned Claude Code binary lives at .local/share/claude/versions/,
so OOM victims named 2.1.220 / 2.1.177 / 2.1.168 are CC sessions, as
are those named claude. Every one of the twelve largest resident
processes ever recorded on this box is a CC session, topping out at
18.4 GB. Everything else killed is 30-55 MB collateral, which clears
the althing daemons by measurement rather than by their own sampling.
sysstat and atop are added because the journal records the moment of
the kill, not the ramp, and names the victim rather than the winner.
atop was not requested and is the one that matters: with a dozen panes
open, only a per-process timeseries says which session was growing.
Not done: a cgroup cap on CC sessions. It is the real mitigation and it
would kill long-running sessions mid-work, so it goes to the operator.
Operator supplied the topology: "the entire rack is on the same circuit,
public ip is served by firewall on the same circuit. load tripped
breaker, entire rack goes dark."
That inverts the argument I committed one commit ago in 3cc55b4. I held
the load attribution partly because a site-wide blackout looked like too
large a blast radius for one GPU box. It is not — it is exactly the
blast radius a shared circuit predicts. The observation I treated as
unexplained was the signature of the mechanism.
Kept the wrong version visible with a superseded marker rather than
editing it away, per the superseded-claims convention: the reasoning
circulated in two althing messages and a peer adopted it.
Holding the attribution as unmeasured was still correct; the argument
used to hold it was reasoning about wiring neither side had seen and
neither side asked for.
Records the finding that outlives the incident: the same circuit powers
ana-ml2, ana-gw, ana-wg, ana-nas and the BMCs, so the load takes every
recovery path with it. Composed with ana-gw's WAN admin being closed
(tunnel-only) and the tunnel terminating on ana-wg, there is no remote
management path to Anaheim during a rack power event, in-band or out.
Open question for the weekend triage: is any of that rack on UPS or a
second circuit?
The record read "power capacity is the open item" next to ana-ml2's
~600 W, which reads as a cause. It is not one. The trip and its timing
are measured; the attribution to the training load is the operator's
working read and the reason for the weekend triage.
The observation that makes the single-load story incomplete on its own
terms: a site-wide blackout is a larger blast radius than one GPU box
accounts for. If ana-ml2's draw were the whole story, ana-nas, ana-wg
and the public address would not have gone dark with it.
Shedding seats may still be the right first move and it is cheap. That
is not the same as having identified what loaded the circuit, and the
distinction matters going into a triage that will act on it.
brokkr-smithy-dev asked how many times 3c was launched rather than
reconstructing it, and their reading was three. It was two.
#1 17:53:33 PDT killed by the power loss at step 80/604
#2 20:58:41 PDT stopped deliberately at 21:07:40, healthy
The phantom third came from a report I wrote at 23:03 narrating the
21:07 kill in the present tense with no timestamp. Every fact in it was
accurate; it was unreadable in sequence against a correctly-observed
22:46 snapshot of an idle GPU.
Evidence is ZFS birth times (a `>` redirect truncates the log but keeps
its birth, so mtime alone cannot separate "rewritten" from "created"),
plus the absence of any mtime under /tank/erp-tune after 21:07:34 — a
relaunch would have rewritten three files there.
Also pins the outage window to 18:14:45-18:17:00 PDT and corrects the
downtime from "~90 minutes" to 1h58m: the last journald entry before a
hard power loss is the last time anything wanted to log, not the moment
of the loss, and here it was 20 minutes early.
Corrects the in-flight header (step 22 -> last-logged step 24, stop
deliberate) and its stale "as of" stamp.
Run 3 trained, gated and dispositioned do-not-serve on a measured 44pp self-harm
guardrail regression that its own preregistered rule passed -- a pooled preserve-list
test cannot see a single-axis collapse. Run 3c (lr 20x cut, single variable) launched,
killed by an Anaheim power-breaker trip at step 80, relaunched, then stopped by the
operator at step 22 pending a weekend power triage.
Also captured: the corpus mix was specified in a unit the optimiser never sees
(45.8% dialogue by context, 24.2% by loss); the dose-response says benefit and damage
are one direction in weight space, so the merge-back measures the problem rather than
fixing it; four guests including the storage SPOF had onboot unset and never came back
from the outage, now fixed with dependency ordering; and a transport failure that
enters a measurement as a value looks like whatever you hoped to find -- which found a
live defect in another agent's instrument an hour after it was reported.
Auto-archived 8 entries to archival-memory.md (Recent decisions: 8, Tried and
abandoned: 0); 4 held back on open deferred-work pointers.
Run 2 is finished, gated FAIL, and serving on the gateway at operator request.
Run 3's corpus was built to brokkr's first recipe and held before any GPU spend:
creative-writing-multiturn is a DECLARED MEGAMIX containing bluemoon, PIPPA,
LimaRP and stheno, and the remix promoted creative-writing AND bluemoon -- the
two roots that overlap, at median jaccard 0.873. Containment, not overlap.
Dedup direction reversed so the primary source survives rather than the copy
inside the bag: bluemoon 67 -> 126 conversations and 38.6% of loss signal, the
largest contributor. Wholly-human share up, megamix share down, total context
unchanged at 12.49M so the operator's settled mix arithmetic survived.
Two structural findings recorded because they outlive this recipe: F1 'excise
PIPPA' removes the ROOT and not the MATERIAL (F2's 250-word floor does that
work, since PIPPA turns cannot exceed 123 words wherever they live), and LimaRP
and stheno remain unchecked against any other root.
Also records the correction I published wrong twice: run 2 was never unstable.
All 46 flags were too_short, the collapse guards fired zero times, and it is the
left tail of a length distribution -- not new to run 2 either, so it is a
property of the recipe and a further base swap will not fix it.
Rewrites the in-flight section: run 1's seat is down, run 2 is up on :8098, and
the base decision the previous snapshot recorded as OPEN is resolved (stock
instruct, operator 2026-08-25).
Four new decisions, and the detail file carries the arc: the two operator calls
that produced run 2, all five gates, the harness commit chain, and the caveat
that its own provenance names a commit AHEAD of the code that ran.
Records three things a future session would otherwise get wrong:
- the mask is proven by the loss-token delta, NOT by the matching p50 step
times -- step time is insensitive to which positions carry loss, so that
check cannot go red on the axis I originally cited it for
- two bf16 26B arms do not fit on one 97.9 GB card (98 GB of weights before
any KV cache), so brokkr's both-arms-in-one-window requirement is a GPU
resourcing call, not a scheduling one
- erp-tune-v1 is still registered in the gateway and returns HTTP 500; the
fix needs a config edit plus a reload that interrupts fleet traffic, so it
is batched for morning rather than done at 2am
Run-01 completed in 7:21:52 (47% faster than the 13.85h round-1 projection),
lora_B gate 205/205 non-zero at median norm 1.708, and the acceptance gate says
it did the thing it was built for: diversity +0.178 against a 0.008 floor (22x),
attractor hit rate -11.3pt against a 2.0pt floor, memorisation 0.0000 on both
arms — which closes the R20 licensed-prose exposure on measurement rather than
argument.
Five new detail files carry the substance:
erp-tune-run2-complete the run, the gate, the noise-floor near-miss
(brokkr was one step from reporting a 13-point
T6 regression sitting inside twice his
instrument's own variance)
mfu-root-caused-attention 8.6% MFU was an accounting artifact; real
utilisation 17-20%, cost was attention on
AMPERE kernels. Two independent methods agreed
to 2.6 points.
nvfp4-serving-pipeline merged weights are MANDATORY — vLLM cannot
serve a LoRA on ANY Gemma-4 — plus the recipe
that silently misses all 11,520 expert tensors
refusal-retention-probe measured base 0/100 -> tuned 29/100, then had
to accept it was the wrong axis
worldtree-b188-b189-and-selene three arcs closed, and a #411 diagnosis I got
wrong twice before a directory probe settled it
Current state rewritten end to end — the previous snapshot had the run in
flight at ~17h with MFU unexplained. Both are now closed.
The open operator decision is run 2's base, deliberately unstaged and flagged
against being filed as a config knob: it is a reversal of the trainee-selection
decision, and the pretrained-base option removes the last non-lexical floor on
the CSAM axis given stage-2-detector-inert and contamination-scan-absent are
both already overridden.
Tried-and-abandoned gains four measured-dead throughput levers, the packing
correction (bucketing wins under sdpa and the conclusion flips under flex — do
not carry it past the backend decision), and the merge-back-undoes-abliteration
trap brokkr caught in his own advice.
Index stays at 291 lines, under the soft cap. No archival this run.
Captures an evening that ran from an OOM crash-loop to a measured trainee base.
The durable lessons, none of which CLAUDE.md can carry: --gpu-memory-utilization
sizes the KV cache and does not cover CUDA context or graphs, which is half of
why a seat that fit on the 21st stopped fitting on the 24th; the other half is
that gen's footprint GROWS WITH UPTIME (38.5 GiB fresh against 45.6 GiB after
three days, same container, same flag), so headroom arithmetic against a
long-running gen measures a moving number. The stale-chat-template trap turned
out to be endemic across third-party Gemma-4 derivatives rather than a one-off,
and it is silent in both directions — wrong prompt when serving, train/serve
skew when tuning. And a benchmark finding was retracted because 12% on a
five-option task is below the 20% chance floor: a below-chance score indicts the
instrument before the model, and a preflight can be thorough while aimed in the
wrong direction.
Records the serving decision for the tuned model with its history intact:
LoRA-on-NVFP4 is preferred if it works, merged weights the expected fallback,
but the archived root-cause says the objection was never NVFP4-specific — vLLM
0.24.0's LoRA application was a silent no-op proven quant-agnostic, and ana-ml2
now runs 0.26.0. Retest before designing around merge; the answer changes what
Eitri's harness must emit, and he is still early.
Auto-archival moved 5 entries (Recent decisions) to archival-memory.md; the
guards held back the rest of the 78 age-eligible candidates because their bodies
carry open deferred-work language, per the keep-when-unsure rule. Index sits at
286 lines, above the ~250 target and reported rather than forced.
The board was on the Australis TERMINAL palette, which is dark-only by design
("Always dark first. No light mode in this system"). Skyfall is the dual-theme
web derivative of the same science, and its bundle turned out to be sitting in
this repo's own git history: a predecessor vendored it on 2026-08-19 and a
later commit deleted it. `git show 45c1995:...` returns colors.css with both
`:root` (dark) and `[data-theme="light"]` (Skyfall Day) intact, plus the
calm-depth layout tokens, the typography scale and Supreme 400/500/700. So the
light ramp is canonical rather than derived, which was the entire objection to
building one.
The visual language moves with the palette. Depth is now the recipe and not a
choice — every elevated surface carries a 1px hairline AND a two-layer shadow,
never one without the other. Radii move to Skyfall's scale, cards at
--radius-lg. Widget stat values move from the display face to mono, because
Skyfall is explicit that numbers and telemetry are always --font-mono. The
full-width aurora ribbon under the tab bar is gone: Skyfall sanctions exactly
two accent expressions, the active rail and hero-only glows, and a decorative
gradient across the chrome is neither — so the colour it carried now lands on
the active tab as a 2px accent bar plus an --accent-soft fill, which is the
rail. Every binding is written against the semantic layer; there are no raw
family tokens and no colour literals left in our own file.
build.py now guards the vendoring instead of advising it. The three token files
are hashed and a mismatch FAILS the build — a vendored file is either
byte-identical to the bundle or it is a fork wearing the bundle's name, and the
theme this one replaces had to be torn out twice for exactly that.
⚠ Homepage's own theme toggle is unreachable, and reaching for it breaks the
dashboard. It renders only when settings.yaml leaves `theme:` unpinned, and
with the key absent the page's data loader throws and its catch branch serves
`initialSettings: {}` — no tab bar, no layout, no i18n. Six force-recreates
over seven minutes all came up empty; restoring `theme: dark` rendered
correctly on the next recreate in 12 seconds, while /api/services returned 200
with fully correct content the whole time. That is the first confirmed cause of
the long-running "tab bar goes missing after a recreate" symptom, and it also
retires the homepage.log-size lead recorded earlier today: rolling the log
aside did nothing during this episode, so that coincidence was intermittency.
So the toggle is ours. conf/custom.js renders it and stores the choice;
build.py re-emits each vendored light block twice, once for an explicit
`data-theme` and once inside a prefers-color-scheme media query scoped to
`html:not([data-theme="dark"]):not([data-theme="light"])` — that :not() pair is
what lets a stored dark choice survive a light-mode OS. Verified against both
OS preferences: load, click, click back, reload, all four correct. `data-theme`
is the control surface; Homepage's own `dark` class stays on <html> and does
not fight, because our rules carry !important on the surfaces Tailwind's
`dark:` variants would otherwise claim.
Two font substitutions, both documented rather than silent: Space Grotesk for
Bespoke Sans and JetBrains Mono for Victor Mono. Only Supreme was ever vendored
here and Skyfall's own notes call Victor Mono user-supplied, so this is a
two-line swap when the real faces arrive.
Dark and light, all four tabs: http://10.100.10.50:8090/b/homepage-skyfall/
The board mixed tools with endpoints. A vLLM seat whose href is a /docs page
sat in the same band as ComfyUI; the MQTT broker and the RustDesk relay, which
have no page at all, sat in Apps; and `Service Networking` was thirteen members
spanning three AdGuards, five Dockges, two Traefiks and four headless agents.
Every group is now one of two kinds and they never mix. TOOLS are expanded and
sit at the top of their tab. ENDPOINTS — an API, a broker, a background agent,
an href that is /docs or /ping or nothing — carry `initiallyCollapsed: true`
and sit at the bottom. Collapsed is not hidden: the eyebrow and its rule still
render, so the tab still says the thing exists and one click expands it.
A second rule fell out of the same pass and now shapes the group boundaries: a
group's members should all carry a widget or none should. A stat strip makes a
card ~50px taller, so one widget card in a row of plain ones opens a void under
the plain ones. That is why AdGuard and Traefik get their own groups rather
than sharing one with Dockge, and it is most of why the old Service Networking
band looked broken. AdGuard (ANA) was the last short card in its row and now
carries the same query/blocked/latency strip as its two siblings — one
infra-ops AdGuard login authenticates against all three instances, verified
against each; it lives in that stack's .env on the host and is vaulted.
The sixteen GPU-backed model seats were deliberately NOT relabelled.
`homepage.group` is read at container creation, so clearer names for
`AI - Inference` and friends would have cost a recreate on six vLLM seats, four
eval seats and four TTS engines — multi-minute model reloads on endpoints peers
reach through the gateway. Order plus `initiallyCollapsed` buys the same
separation for nothing, so those names stay as they are on purpose.
28 containers that ARE cheap to bounce were relabelled, across five hosts, via
rerunnable elway playbooks. Their label steps are gated on the old value still
being present, so a second run reports skipped rather than churning. Two verify
steps were wrong on first contact and are fixed with the reason recorded: the
traefik check raced its own recreate, and asserting a model seat is "running"
cannot answer "did I bounce it" when a seat may be legitimately stopped —
container age can, and now does.
The canonical stacks/ tree was synced to the deployed labels afterwards, so
intent and reality agree again on all fourteen tracked stacks.
Also documents the real nature of the post-recreate blank dashboard, which cost
~25 minutes here and an hour on 2026-08-19. `initialSettings":{}` in the served
HTML is the catch branch of the page's data loader, not a warm-up and not a
cache — and the error can vanish entirely, because the logger is assigned inside
the same try and the catch only logs if the logger exists. Ruled out by
measurement this time: all four API routes return 200 with correct content while
the page serves {}, and the previous known-good settings.yaml reproduces it
identically. The README now carries the one-command test and the next lead.
Before/after, all four tabs: http://10.100.10.50:8090/b/homepage-relayout/
The board's card width changed at every group boundary because `columns:` was
being tuned per group under the 2026-08-18 "columns = member count" rule. That
rule is retired: it sets `lg:grid-cols-N` for one group, so it fixes that
group's CARD WIDTH, not its density. Measured on the live board, Notes rendered
a single 1464px card, News and Media 728px, Eval & Retrieval 286px, everything
else 360px. All 20 groups are now `columns: 4` and every card renders at 360.
`.service-name` reserved a 78px status gutter with `padding-right` and relied
on `overflow: hidden` to hold it, but overflow clips at the PADDING box — the
gutter was spill room the title printed straight through. Six cards on the AI
tab rendered their name underneath their own status pill, measured by testing
the title text node's box against the status cluster's. The intended ellipsis
never fired either: it is painted by whichever block's own line overflows, and
that is the anonymous box around the bare title text node, which does not carry
`overflow`. The gutter holds by wrapping now, and the description opts back out
of it with a negative margin since the pill only ever covers the first line.
Scriberr's `homepage.group=AI Systems` named a group absent from `layout:`, so
it had no `tab:` and rendered on all four tabs — the same defect as UltraSeedbox
in 2026-08-18, arriving this time from a container label. Relabelled to
`AI - Audio Tools`, where the other ASR seats already live. The
`homepage.group=AI Systems` sample in the repo-root CLAUDE.md was the source of
the name and now carries the constraint, plus the fact that a labelled
container is discovered from any of the five configured engines and must not
also be listed in services.yaml.
Also: descriptions clamped to three lines so a five-line outlier stops dragging
its row 50px taller than its neighbours; icon ramp overridden off slate-400 ->
slate-700, which was sinking the bottom half of every glyph into the card fill;
bookmark groups and Jellyfin's trailing stream rows brought into the card and
eyebrow vocabulary; group gap 10px -> 22px now that width no longer separates
them.
The icon override sits on `html[class]`, not `:root`: Homepage sets the same
variables on `.theme-slate`, which is on the <html> element, and a class beats
`:root` on the same element.
Verified with Playwright against the live board — per-group card width, card
height spread, and a geometric title-vs-status collision check, before and
after. Before/after captures: http://10.100.10.50:8090/b/homepage-relayout/
Rewrites the in-flight section, which had gone stale in one place
(speaches is stopped, not live) and did not reflect a session in which
everything opened was also closed. Three detail files carry the bulk:
the FortiGate's public surface reduced to nothing including the ACME
listener, Scriberr's deployment and the three upstream defects it
required working around, and the ESH DNS repair that also made the
IPv6 naming scheme real on three hosts.
The tunnel entry in the decisions log described a cipher change as
proposed and pending; it has since been attempted, found impossible in
the form intended, and resolved differently, so the line now points at
the outcome rather than the intention.
New decisions cover the cipher adoption and the finding that the
per-flow ceiling belongs to the UniFi gateway's software cipher rather
than the firewall, the administrative closure, the transcription
deployment, the DNS repair, the retirement of an ASR service whose
only consumer was abandoned, and a database VM that until now had no
fleet identity and no vaulted credential at all.
Three approaches are recorded as abandoned: an AEAD cipher the far end
cannot express, an upstream DNS setting the gateway accepts and
ignores, and a scheme to claim unused delegated prefixes that founders
not on the prefixes but on having to rebuild a firewall policy to use
them.
