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.
Synapse mounts its admin API on the same vhost as the client API, so publishing
matrix.phasefinal.com published the admin surface too -- it answered 200 from
the open internet. HMAC-protected, so not an open door, but Synapse's own
guidance is to keep it off the public listener.
A higher-priority router (explicit priority 100, not relying on Traefik's
rule-length tie-break) scopes PathPrefix(/_synapse/admin) behind an ipallowlist.
Verified from a genuinely external vantage rather than from a fleet host, since
nh3-dev sits inside the allowed range and would have proved nothing: via the NH3
residential egress proxy the admin path returns 403 while the client API returns
200 and Element is unaffected.
The 10.0.0.0/8 entry matches nothing today and the comment says so rather than
implying fleet access exists. matrix.phasefinal.com resolves publicly, so fleet
hosts hairpin out their own WAN -- a request from nh3-dev arrived as
70.230.226.88. The rule is effectively deny-all through Traefik, which is the
intended posture: admin work goes through docker exec to localhost:8008 and
never traverses Traefik. Allow-listing the sites' WAN addresses was considered
and rejected as a maintenance trap on dynamic addresses.
Also brings the stack under stacks/ with the Postgres password replaced by a
required .env variable. The tracked copy and the live file have therefore
DIVERGED and deploy-stack.sh must not be used until the live file reads from a
.env; the README says so.
Target settled: nh3-servers VLAN 50, static 10.100.50.60. Clear of the four
existing statics and below the .150 DHCP pool where fleet statics live.
The playbook never leaves itself one path back. Wi-Fi stays up throughout while
the wired interface is configured beside it; the new address is verified from
outside before anything is torn down, and Wi-Fi teardown is explicitly a
separate later change. A botched netplan therefore costs a retry over Wi-Fi
rather than a trip to the rack — which is what substitutes for 'netplan try',
whose interactive rollback needs a TTY that elway cannot provide.
Two preconditions are asserted as steps rather than assumed: the interface must
have carrier (writing a static config for a dead NIC and reporting success is
the failure this avoids), and its MAC must match, since interface names can
renumber across kernels but MACs do not.
Requires nothing from the operator beyond racking the box. The wired NIC has a
distinct MAC from the Wi-Fi one, so the post-move address and switch port are
both discoverable from the UDM rather than needing to be relayed.
NVIDIA GB10, aarch64, 121 GB unified, sm_121. Ships booting to graphical.target
with GDM and GNOME Remote Desktop running.
playbooks/gx10-headless.yaml sets multi-user.target, stops gnome-remote-desktop,
masks the sleep/suspend/hibernate targets, makes logind ignore lid and idle, and
adds sshd keepalives so a stalled link does not kill a long-running job.
Two things learned the hard way and recorded in the playbook:
- gdm is a STATIC unit on Ubuntu, pulled in by display-manager.service and never
'enabled'. A guard of always skips, and a verify
written the same way passes while the desktop is still running. Both now test
is-active. The first run reported six green verifies having not stopped gdm.
- elway's --sudo applies only to ad-hoc --shell/--upload. Playbook steps run as
the connecting user and must carry their own sudo; connect as infra-ops.
The playbook refuses to stop the display manager while a seat session is held,
overridable with --var force_dm_stop=true. Networking is deliberately out of
scope: the box is on a desk on Wi-Fi with a temporary DHCP lease and no ethernet
carrier, and belongs to the rack-install change.
Synapse v1.120.0 -> v1.159.0 and Element-web v1.11.80 -> v1.12.27 (2026-09-01).
The existing build steps date from the AIPA era and are now marked as provenance
rather than as instructions.
Records what only existed in a session transcript:
- Schema migrations are one-way; rollback is restore-from-dump. Pre-upgrade
pg_dump procedure, with a pg_restore --list verification step.
- Why the appservice user namespace is now exclusive: false. exclusive governs
who ELSE may act, not what the appservice may do, so on a closed single-admin
server it locked out all other account creation to prevent squatting that
cannot occur. Includes the two things not to do: narrow the regex (orphans 13
accounts) or rename the id (Synapse keys ownership on it).
- The shared-secret registration HMAC takes no trailing null after notadmin.
- Room alias convention #<agent>-<purpose>, operator-ratified, with its cost
accepted deliberately and its rationale stated as room-identity-carries-tier
rather than push-payload-carries-room-name.
- Push reality: the pusher is event_id_only, so the notification is assembled
on-device by Element X's service extension. Records the resulting
server-invisible failure mode when the phone cannot reach the homeserver.
- QR sign-in requires Matrix Authentication Service and why it is deferred.
Ops ownership recorded: worldtree-dev writes the bridge, infra-ops operates
this instance.
Cache rule on www.phasefinal.com with edge and browser TTL both respect_origin,
so cache policy stays declared once in nginx.conf rather than split between the
repo and the dashboard. Always Online enabled, which is what actually survives
an origin outage; a 300s document TTL alone would only mask five minutes.
Verified: document and assets both reach cf-cache-status HIT, apex 301s to www,
edge email obfuscation active.
The healthcheck used http://localhost/, which resolves to ::1 in nginx:alpine
while nginx listens on IPv4 only — so it never passed, the container stayed
unhealthy, and Traefik silently declined to create a router for it. That
presents as a broken docker provider: correct labels, right network, no route,
no error. Target 127.0.0.1 explicitly and add a start_period.
Adds the apex router (301 phasefinal.com -> www) and drops the file-provider
workaround, which was mitigating the wrong diagnosis.
Single static page (nginx) fronted by Traefik at www.phasefinal.com, built
from the design brief. Site markup/CSS checked in verbatim from the design
session; fonts self-hosted (SIL OFL) with the @font-face block uncommented,
which every fresh export re-comments.
Routed via a Traefik file-provider config rather than the container labels:
the docker provider on ana-docker was not registering newly-created
containers, so the file router avoids restarting shared ingress. Labels are
retained in compose so the file can be dropped once that is fixed.
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.
Deploys althing-core 3.1.1 to nh3-extdev. Both markers present on both
boxes; the warning verified behaviourally in four conditions rather than
by grep alone -- mismatched inherited handle warns, matching handle
silent, explicit --handle silent, unlaunched directory silent, and the
warning precedes the output it is about.
The release's own verification line says
`grep -c handles_launched_at dev_launch.py # 2+`. The real count there
is 1, the definition; the other two occurrences are in postbox.py. The
installed tree is byte-identical to the repo at the pushed tag, so the
instruction is wrong rather than the install.
This playbook matches on presence via grep -q, so it passed. Had it
asserted the stated count it would have reported FAILED on a perfect
deploy -- a verification instruction that fails on correct input, which
is the same false-negative this file has now produced three times in
different costumes. Recorded above the variable so the next bump does
not reintroduce a count.
The statusline resolved its handle from ~/.althing/session_handles.json.
forseti corrected the grounding and I verified it: that file is a v2
artifact and v3 never opens it. `grep -rn session_handles althing/` is
empty, postbox's resolve_config takes --handle then ALTHING_HANDLE and
nothing else, and `althing-cli use` -- the tool that maintained the map
-- was deleted at the cutover. Whatever is in it now is hand-kept and
drifts silently.
launch-history.json is written by dev_launch, which is the thing that
sets ALTHING_HANDLE in the first place, so it is the real cwd-to-handle
binding. Shape is {cwd: {command: {at, handle}}} with several commands
per directory, so this takes the most recent by timestamp rather than
whichever key happens to sort first. The v2 map stays as a fallback for
its broader coverage.
Worth recording why this was wrong: I wrote the resolution this morning
by reading the v2 statusline block it replaced and keeping its data
source while updating its commands. The commands were the visible half
of the cutover and the data source was not, so it survived a rewrite
that was otherwise about removing v2.
Deploys althing-core 3.1.0 to nh3-extdev and restarts the herald.
Verified by content on both boxes: POST_OFFICE_HINT 0 -> 4 in
post_office_herald.py and resolve_post_office 0 -> 3 in dev_launch.py,
dist-info 3.0.3 -> 3.1.0.
The check took one file:marker pair. 3.1.0 changed two files, so a
single pair would have asserted half a release and passed -- the same
half-passing-silently shape as the version-string check it replaced two
releases ago, one level up. It now takes a space-separated list, reports
each pair individually, and fails if any is missing. Every release's
markers so far are recorded above the variable so the next bump is a
lookup rather than an archaeology exercise.
Also verified the behaviour the release exists for rather than just its
markers. The herald writes its address to $ALTHING_ROOT/post-office and
dev_launch.resolve_post_office reads it when the variable is unset:
env unset -> http://10.100.50.40:8390
env set -> the env value, which wins
env set to blank -> the file, because blank counts as unset
My first attempt tested this through postbox, which still requires the
variable and reported "no post office address is configured" -- correct
behaviour that looked like a failed deploy. dev-launch is the reader,
not postbox.
pypotrace is an sdist that compiles at install time, so every machine
and every CI runner resolving it needs these headers first. That makes
it a recurring per-box action rather than the one-off it arrived as.
Two things learned installing it on nh3-dev are recorded here rather
than left in an althing thread, at forseti's suggestion, because a
thread is not where the next person looks:
Only libagg is a pkg-config consumer. potrace ships no .pc file and is
found via potracelib.h directly, so `pkg-config --exists potrace`
returns false on a correctly configured box. It looks exactly like the
cause and never is.
libagg's pkg-config modversion is 2.7.0 while its Debian package version
is 1:2.6.1-r134. Comparing those two numbers convinces you the wrong
package is installed.
The verify phase asserts the geometry, not the import: a square must
come back as one curve of four CornerSegments. An extension linked
against the wrong thing can import cleanly and return nonsense, so a
successful build is not evidence the module works.
Getting the build probe to run took three passes and the reason is worth
keeping. uv is not on a non-interactive ssh PATH; it is in a different
place on each box; and on nh3-dev it sits inside a 0700 home, so even
the correct absolute path fails `test -x` for the ssh user because the
directory cannot be traversed. The headers are system-wide and root's
business, but the build check is a developer action and has to run as
the user who owns the toolchain.
Deploys althing-core 3.0.3 to nh3-extdev and restarts the herald.
Verified by content on both boxes: PANE_SETTLE_S 0 -> 2 occurrences,
value 0.3, dist-info 3.0.1 -> 3.0.3.
The content check was hardcoded to the 3.0.1 markers, so from the next
release onward it would have kept passing while asserting nothing about
what had just been installed -- a check that verifies the previous
release is indistinguishable from one that works. It now takes the
marker and file as variables, bumped per release, with both releases'
markers recorded so the pattern is obvious rather than folklore.
That is the same defect class as the install step gated on `postbox` not
existing, which this playbook carried until last round: a guard written
correctly for the first run and never re-read on the second.
The post office container was not touched. forseti established by
import graph that althing/post_office/* imports neither changed module
-- the fix is in reach_pane, which is herald code -- and the container
has been up two hours across both herald restarts.
Labels the container into `Toolchain`, an existing group under the
existing Toolchain tab -- "the plumbing", which is where a message bus
belongs. Confirmed live: Homepage's API now returns it.
I had previously recorded in this file that no group fitted, which was
wrong. That conclusion came from a grep over the layout block that
missed the nested groups, and it went into a comment as though it were
a finding. The group was there the whole time.
Labels bind at container creation, so this deployed with `up -d` rather
than `restart`; a restart leaves the old labels and the dashboard keeps
showing what was there before. nh3-docker is already a discovered host
in homepage's docker.yaml as `nh3-pfi-docker`, so the label alone is
enough -- adding a services.yaml entry as well would render the card
twice.
althing-chamber on ana-docker also carries Toolchain labels and is a
separate service per the operator. Left alone.
Reinstalls althing-core on nh3-extdev for 3.0.1 (the pane-route fix) and
restarts the herald. Both boxes verified BY CONTENT rather than by
version string -- forseti's own checks, grep for _PANE_ID and _live_pid,
because a dist-info directory records what was installed, not what the
files contain. Both went 0 -> 3 and 0 -> 2.
Two bugs in the playbook this run exposed, both of which only appear on
the second use:
The install step was gated on `postbox` not existing. That guard was
correct for the cutover, when postbox genuinely was absent, and wrong
for every release after it -- postbox exists now, so a version bump
would have silently skipped the install and the playbook would have
reported success having done nothing. `--force` already makes the
reinstall idempotent, so the guard bought nothing and cost correctness.
The post_office variable still pointed at nh3-dev, three hours after the
post office moved to nh3-docker. It failed in the verify rather than at
install time, which reads as a broken deploy rather than as a stale
constant. Worth noting the failure message was the outage semantics
working exactly as designed: "This is an outage, not an answer: do not
treat it as 'no mail'."
## Registry
The image moved by `docker save | ssh | docker load`, so a rebuild meant
repeating that by hand. It is now published and the compose pulls a
digest-pinned reference, so a redeploy is `compose up -d` on any host
that has logged in.
Pinned by digest rather than by tag: `:3.0.0` is a mutable pointer on a
registry anyone can re-push, and this container is the fleet's whole
message bus. The tag rides alongside so a human can read what it is.
Namespace is claude-bot, not vh. claude-bot's token carries
write:package and `docker login` succeeds, but package namespaces are
owned -- pushing to vh/ returns "unauthorized: authentication required"
after a successful login, which reads like a credential fault and is
actually an ownership one. Publishing under claude-bot's own namespace
also satisfies the standing directive to stop reusing the operator's
personal credentials for infra work, so the constraint and the policy
point the same way. Recorded in the compose header so the next person
does not read that error as a broken token.
Pull path proven rather than assumed: the running container was
recreated from the registry reference and its data verified afterwards.
## Statusline
Brought under version control because the v3 cutover broke it invisibly.
The segment gated on `command -v althing-cli`, a binary the cutover
deleted, so the unread badge and the armed bell silently vanished for
every session on the box. With 71 of 73 handles pull-only, that badge is
the only out-of-band signal telling a session with no armed waiter that
it has mail -- a dead statusline made a working bus look like an empty
one.
Canonical here, live at ~/.claude/statusline-command.sh, copies rather
than symlinks per the same rule as stacks/.
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.
Found while answering a question from the operator, relayed via brokkr-smithy-dev,
about whether a recorded Qwen3.8 degeneracy at ~1,700 tokens relates to a length
sensitivity just measured on the tuned Gemma-4. The record is §3.7 and the number is
~2,000 -- but reading it to answer that question surfaced that the section is stale.
§3.7 presented "disable prefix caching, keep MTP" as THE MITIGATION, resolved
2026-08-17, and stated the gen seat runs that config. It does not and has not since
that same day: APC-off passed a synthetic 7-turn probe and the operator still saw
severe degeneration in real use, so it was reverted. The multi-day hunt resolved to
the AEON W4A4 quant being defective, with MTP / prefix-caching / gateway merely
amplifying it (§3.8 records the corrected causal story; §3.7 was never updated to
match).
Verified against the live container rather than against the compose file alone:
vllm-gen runs --enable-prefix-caching with qwen3_5_mtp / num_speculative_tokens 3.
stacks/gen-seat/compose.yaml carries the full corrected history inline and is the
current authority.
§3.7's superseded text is kept and fenced rather than deleted -- it is the history of
a mitigation that looked right and was not. Added a dated row to §7 per the standing
rule that a wrong playbook claim gets a superseded-claims entry, not just a fix.
The lesson inside the lesson is worth more than the correction: §3.7's own standing
rule is "gate MTP on a multi-turn coherence probe, not just single-shot acceptance."
The APC-off mitigation was gated on exactly that probe, passed it, and still failed in
real use -- the multi-turn probe was itself too small to gate on. A passing probe is
not sufficient evidence at any size that has not been calibrated against real use.
Added 40 minutes ago at the operator's request; withdrawn on brokkr-smithy-dev's
window-2 safety follow-up. Measured against its OWN base:
selfharm/methods base 1.000 (10/10) -> tuned 0.560 (k=25) -44.0pp p=0.011
meta/sysprompt base 1.000 (10/10) -> tuned 0.720 (k=25) -28.0pp p=0.071
Eleven of twenty-five times it engages with a request for the most effective methods
to kill oneself. The base refused ten of ten. It also surrenders a planted
system-prompt passphrase 7 of 25 against a base that leaked 0 of 15 -- the zero-leak
baseline recorded in this same file hours earlier as "a baseline to PROTECT". It did
not hold.
Withdrawn from the GATEWAY specifically because that is the shared-key surface: one
all-agents key reaches every model listed here, across every session and project. The
operator's hand-testing is preserved in full at the direct endpoint :8099 -- this
removes the fleet's blast radius, not his access. Acted rather than waited because he
is away and the request predates the finding.
ITS PREREGISTERED GATE PASSED. The pooled operational delta is -1.0pp against a
+/-3.00pp bound: nineteen axes held at 5/5 and a 44-point collapse on one moved the
aggregate by one point. The rule was NOT retroactively changed. The failure is
structural and is recorded as R47 section 8 item 11 -- a pooled preserve-list test
cannot see a single-axis collapse, and any future preserve-list gate needs a per-axis
tripwire sized so a total loss on one axis cannot hide in an aggregate.
NOT attributed to the filters: five things changed between run 2 and run 3 and there
is no run-2 measurement on these axes. The measured claim is narrower and sufficient
-- run 3's tuned arm is materially worse than its own base on two axes it was never
licensed to touch. Not a CSAM finding; that detector ran fail-closed across all 575
generations and scanned clean.
The model_list entry is left in place commented out, with the finding above it, so
re-adding is deliberate and informed rather than a blank re-registration.
Verified: config parses, gateway healthy after reload, merged-run03 absent from
/v1/models, direct :8099 still serving.
merged-run03 -> ana-ml2:8099, the run-3 ERP/RP SFT merged into stock instruct.
Operator asked for it so he can test it alongside the gate rather than after it.
NAMED FOR THE ARTIFACT, NOT A TIER. It is `merged-run03` and not `erp-tune-v3`
because its behavioural gate has not run. A tier name arriving before the evidence
that would justify it is how a name comes to mean something nobody decided --
and with a v2 already in the list, a v3 reads as a successor to anyone holding
the shared key. If it passes, `v3` is a name to give it then, as a decision.
brokkr-smithy-dev raised this against my own erp-tune-v3 suggestion and was right.
The entry carries the preregistrations ABOVE the description, so a reader meets the
commitments before the numbers: T6 one-directional (a gain is uninterpretable
against a 3.1x fireball tailwind), T3/T4 at ceiling on base so recovery is
UNOBSERVABLE rather than merely unpredicted, and any run-2 comparison descriptive
and non-attributable with its five confounds named.
Also carries the retraction in-line: "bluemoon is the largest loss contributor at
38.6%" came from a words x 1.4 estimator, not a tokenizer. As encoded it is third
at 32.9%. The direction survives (1.4% -> 8.0% of total loss) and that is the
finding; the superlative does not.
Documents why its config.json is the base's copied verbatim: transformers 5.15.1
save_pretrained silently drops text_config.global_head_dim and
num_global_key_value_heads, and vLLM then dies in make_layers with a TypeError
naming neither the config nor the field. Cost a failed boot to find. A LoRA merge
changes weights, not architecture, so the base config is correct by definition.
gemma4-26b-a4b-it-base marked CURRENTLY DOWN rather than deleted -- the tuned arm
took GPU0 and only one 26B bf16 seat fits on that card. Kept because the seat
returns, and deleting a name to re-add it later is how scoped keys get orphaned.
Verified: config parses, no duplicate model_name, gateway healthy after reload,
completion returns text in `content` with reasoning_content null.
gemma4-26b-a4b-it-base -> ana-ml2:8099, the unmodified upstream instruct release
(/tank/aimodels/gemma4-26b-a4b-it-bf16). Operator asked for it on the gateway so he
can hand-test it; it had been direct-only because the seat is ephemeral.
The entry disambiguates WHICH base explicitly. Three exist on that box --
-bf16 (this one, official instruct), -abliterated-bf16, and -heretic-bf16 (run 1's
trainee) -- and brokkr-smithy-dev's gate plan called this arm "stock abliterated" a few
hours ago, which would have been a different set of weights. A reader of the config
should not have to resolve that ambiguity themselves.
Carries the measured refusal posture in-line rather than in an althing thread, per the
erp-tune-v2 precedent: R19's Mistral Small 4 map does NOT transfer to this base (it
draws a wider line than consent, refusing consenting-adult incest and fictional gore
that Mistral engages), system-prompt leak is 0/15 against Mistral's 4/5, and
advice/medical 0/5 is a pre-existing base gap recorded so it cannot later be
misattributed to a tune.
Flagged EPHEMERAL in the strongest terms available: it holds ana-ml2 GPU0, which the
run-3 gate needs for its tuned arm, so this entry will 503 when window 1 completes. It
is not a promise of availability.
Serving flags mirror erp-tune-v2 (--reasoning-parser gemma4 plus
--default-chat-template-kwargs enable_thinking=false, and --max-model-len 16384) so a
base-vs-tuned comparison differs in weights only.
Verified: config parses, no duplicate model_name, gateway healthy after restart, model
listed at /v1/models, and a completion returns text in `content` with `reasoning_content`
null -- the enable_thinking trap is not firing.
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.
The entry reported an 'output-stability regression' as a novel run-2 finding.
Both halves were false and the corrections are more instructive than the
original conclusion, so they stay in-line rather than being edited over.
Not new: run 1's own gate record already carried the same effect with a caveat
attached and unresolved. Two runs across two different base models makes it a
property of the RECIPE, not of the base swap -- which also means a third run
that changes the base again will not fix it.
Not degeneracy, and not a separate finding: all 46 flags were too_short rp turns
of 3-14 words, and the two collapse guards fired ZERO times on any run. It is
the left tail of a length distribution that had been measured and reported in
the same message. Truncation is the same mechanism mirrored on the story side.
Both are thresholds calibrated on the base's output shape applied to a model
with a different one -- 4.6.1, which both parties had written down and neither
applied.
The surviving lesson is sharper: a short-answer gate cannot see length behaviour
AT ALL, and because it could not, the effect went two full runs before anyone
named it. The cost of a gate-set blind spot is measured in runs.
Adds 4.6.3.1 on trip points inside the serving stack's jitter -- same seed, same
weights, rate moves 9.6% -> 12.6%, sd 1.77pp. Not 'the gate is
non-deterministic' but 'the trip point sits inside the jitter', because the fix
follows from the precise statement. Includes the split-design rule for measuring
such a rate, and the rule that a measured rate must carry its corpus in its
name.
