The fleet IPv6 work was justified primarily by the expectation that ESH
fiber landing behind CGNAT would break Site Magic on IPv4, making v6 the
escape hatch. The fiber cutover provided a free natural experiment and
the premise does not hold.
Cox was unplugged, ESH failed over to the 5G WAN (already configured
failover-only, so this needed no intervention), and the resulting WAN
address is 192.168.200.111 -- RFC1918, double-NAT, no inbound path at
all, which is strictly worse than the CGNAT that was feared. Site Magic
stayed up throughout: all four ESH hosts reachable, ssh and command exec
working, 20MB pulled over the tunnel, latency 15ms -> ~46ms as expected
for cable to 5G.
The mechanism is visible on the device: magic_site_to_site_vpn holds
only `enabled` plus a WireGuard keypair, with peer orchestration in the
UniFi cloud and no WAN binding of any kind. NH3's edge is publicly
reachable, so the NAT'd side dials out and never needs reachability.
Consequence: no addressing outcome on the new fiber -- public, CGNAT or
double-NAT -- threatens the inter-site tunnel. IPv6 stays worth doing on
its own merits but stops being urgent, and stops gating anything.
Also worth recording that Site Magic cannot be pinned to a WAN. It rides
whichever uplink is active, so the only lever is failover priority --
which moves all site traffic, not just the tunnel. The existing
failover-only config on WAN2 already handles a primary-WAN outage
correctly and needed no change.
pve-manager 8.4.11 -> 8.4.20, corosync 3.1.9 -> 3.1.10-pve2, and kernel
6.8.12-42 staged on the /boot LV. dpkg clean, nothing outstanding for
apt -f install, all PVE services active, cluster quorate, no unapplied
conffiles. Reboot deliberately deferred at operator request, so the host
still runs 6.8.12-13 until a chosen window.
This validates the GRUB fix from 061c4b7 under the exact condition it
was written for. update-grub regenerated entries for the new kernel and
entry 0 -- what GRUB_DEFAULT=0 selects -- is now
/vmlinuz-6.8.12-42-pve with root=ZFS=nvme/ROOT/pve-1, supplied by the
grub.d drop-in since grub-mkconfig cannot derive the pool name itself.
The old kernel keeps correct entries as a fallback and the ext4 rollback
entry is untouched. Had the fix not landed first, saved_entry would
still be pinned to 6.8.12-13 and the host would boot the old kernel
indefinitely -- 161 security updates installed and never run.
/boot holds both kernel sets at 176M used of 488M, confirming the 512M
LV carved out of swap was sized correctly.
Adds a ZFS snapshot step to the upgrade playbook, taken automatically on
ZFS-root nodes before any package lands. That is the first real use of
the boot-environment upside the migration was meant to unlock: rollback
for this upgrade is now `zfs rollback -r
nvme/ROOT/pve-1@pre-upgrade-20260818T141652Z && reboot` rather than
archaeology in dpkg. Also documents that the corosync bump restarts
corosync mid-upgrade, which on a 2-node cluster is a brief quorum event.
Sibling to model-quantization-playbook.md, and it exists for the same
reason that one does: hard-won lessons were dying inside per-host
runbooks where nobody finds them until after repeating the mistake.
Six entries seeded from the esh-pve-nas migration, all of which would
bite identically on any other host:
1. mount --rbind into a chroot needs --make-rslave, and losing cgroup2
impersonates failing root-disk I/O closely enough that it was
misdiagnosed as exactly that.
2. A reboot is not confirmed until the host is observed DOWN; "never
rebooted" and "rebooted fast" are indistinguishable otherwise.
3. Assert the effective value, not the presence of a substring. Grep
proves presence; only evaluation proves effect.
4. Ask the server who its clients are -- documented dependent lists rot.
Plus the corollary that an idle hard NFS mount blocks and resumes, so
quiescing means stopping consumers, not always unmounting.
5. The scoped-looking command can be the dangerous one; setting a ZFS
cachefile on one pool of three would have stopped the other two from
importing at boot.
6. Long uptime hides breakage, and a forced look is worth more than it
appears -- one migration surfaced an 82-day-dead pvestatd, a 126-day
hung vzdump, a VM in prelaunch for four months, and an undocumented
cluster, none of them caused by the work.
Carries a superseded-claims table so corrections are dated rather than
silently edited, same discipline as the quantization playbook. The ESH
runbook now links here so the general rules are reachable from the
specific story and vice versa.
171 packages, pve-manager 8.4.11 -> 8.4.20, kernel 6.8.12-16 -> 6.8.12-42,
corosync 3.1.9 -> 3.1.10-pve2. dpkg clean, no unapplied conffiles, no
failed units, cluster quorate with both nodes visible after the reboot.
Adds a reusable pve-node-upgrade playbook (upgrade only -- reboot stays a
separate deliberate step, since it has cluster and NFS consequences the
playbook cannot see). It guards on quorum and free space, snapshots
/etc/pve and friends first, uses --force-confdef/--force-confold, and
surfaces any .dpkg-dist files that policy left unapplied so they are not
silently ignored.
The reboot needed a forced guest stop, operator-authorised after the risk
was surfaced. Two obstacles, only one of them ours:
- A vzdump had been hung since 14 April -- 126 days, stalled at 0% of
256 GiB -- holding lock: backup on VM 102, which had therefore been
sitting in QEMU prelaunch that entire time. Killed by explicit PID; 102
is now cleanly stopped rather than half-alive.
- esh-vm-db would not shut down: its guest agent had died and ACPI went
unanswered. Most likely ours -- it hard-mounts /mnt/backup from CT 103,
which we deliberately left mounted through the NAS reboots.
PostgreSQL survived the hard stop. It had checkpointed five minutes
prior, so recovery replayed 56 bytes of WAL in 0.02s and came up ready;
all four databases present and queryable. That was lucky timing as much
as anything -- a hard stop mid-checkpoint on a busy database would not
read the same way.
The reboot also repaired esh-vm-db, which had silently lost sshd, mongod
and its guest agent. All three are back.
The cutover left saved_entry=pve-zfs-root, a hand-authored 40_custom
entry hardcoding /vmlinuz-6.8.12-13-pve. The pending upgrade installs
proxmox-kernel-6.8.12-42, which made that a trap with two exits: if -13
were autoremoved the default entry would point at a missing kernel and
the host would need console recovery it has no IPMI for; if -13 survived
the host would silently keep booting the old kernel, so 161 security
updates including a kernel would install and never run.
That entry was written as a one-time cutover target. It was never fit to
be the standing default across kernel upgrades, and this is remediation
of that, caught before the upgrade rather than after.
Fix is to stop hand-authoring the ZFS entry: GRUB_DEFAULT=0 boots the
first auto-generated entry, which grub-mkconfig regenerates for the
newest kernel on every install, and which /etc/default/grub.d/zfs-root.cfg
already corrects to the pool-qualified root=ZFS=nvme/ROOT/pve-1. grubenv
is cleared so nothing overrides it.
The rollback entry stays pinned, which is correct rather than an
oversight: it boots the untouched ext4 root on the DOM, whose /boot is
never regenerated because update-initramfs writes only to the /boot LV.
That kernel genuinely never changes.
Also adds a reusable safe-reboot playbook for this host, carrying the
constraints that are easy to forget: quiesce the hard-NFS clients first,
the other cluster node goes read-only while this one is down (quorum 2,
no qdevice), and a failed boot has no auto-fallback and no remote
console.
Two findings from chasing node `pve` showing dark in the UI.
esh-pve and esh-pve-nas are a 2-node cluster (esh-pve-cluster, expected
votes 2, quorum 2, no qdevice). This was undocumented, and last night's
migration rebooted one of the members without accounting for it. Nothing
broke -- quorum is intact and both nodes report the same ring id -- but
that was luck. Rebooting either node drops the survivor below quorum and
makes its /etc/pve read-only until the partner returns. It matters for
the pending confirmation reboot and the 225-package upgrade, both of
which take a node down.
The dark tile itself was NOT last night's doing. pvestatd SEGV'd on
2026-05-28 and had been dead 82 days; the journal has nothing between
that crash and the restart today. It is only the reporting daemon, so
the node stayed quorate and healthy with all services active and all
three guests running the whole time -- the UI simply had nothing telling
it the node was alive. Fourth SEGV in that unit's history, so treat a
recurrence as expected and consider a watchdog: nothing alerts on it,
and the sole symptom is cosmetic enough to go unnoticed for months.
Root is now nvme/ROOT/pve-1. The USB DOM keeps the ESP and /boot but is
out of the runtime I/O path, so a bus reset can no longer drop root from
under a running hypervisor. All five guests healthy, three pools ONLINE,
system running, ext4 pve-root intact and unmounted as the rollback with
its own kernel and initrd. zfs-import-cache is now the active import
path -- the all-three-pools cachefile fix doing its job.
The window cost an unplanned outage, and the cause was this repo's own
tooling rather than the migration.
The staging chroot ran `mount --rbind /dev` and /sys with no
--make-rslave. On systemd `/` has shared propagation, so the cutover's
`umount -R` propagated back into the live host and removed the real
/sys/fs/cgroup, /dev/pts and /dev/shm. With cgroup2 gone systemd-logind
could not create a session: ping fine, TCP fine, SSH authentication
succeeded, resident daemons kept serving -- and every new exec hung,
including /sbin/reboot, so the reboot never ran at all.
It impersonates failing root-disk I/O almost perfectly, and I called it
as the DOM dying. That was wrong. dmesg had the answer throughout: the
DOM attached cleanly with no errors, and the last log timestamp was
12114881s -- 140 days -- meaning this was still the original boot. A
down-detector had also never reported the host down, which I read as a
fast reboot rather than as no reboot.
Fixes and guards:
- --make-rslave after every rbind, plus a guard that refuses to proceed
while any chroot bind still reports shared propagation.
- Confirm a reboot by observing the host DOWN, not by watching for it to
come back. Those two states are indistinguishable otherwise.
- Blast radius now measured from the server: `ss` inside CT 103 found
five NFS clients, not the two documented. The new one that mattered is
esh-vm-db, hard-mounted and unreachable by ssh. Left mounted on
purpose and it came through read-write.
- grub-reboot's one-shot does NOT work here: grubenv sits on an LVM LV
which GRUB reads but cannot write, so next_entry survived the boot
that consumed it. Steady state is saved_entry=pve-zfs-root with no
next_entry. There is no auto-fallback on this host and no IPMI.
Recovery needed no console: an idempotent cgroup2/devpts/shm remount
landed in the brief windows where exec succeeded. No data was lost, and
neither the DOM nor any pool was ever at risk.
Operator ruled 2026-08-18 on the 5-character PARK_API_KEY flagged during
the v1.0.0-beta.2 deploy: leave it. The henge is LAN/WG-internal and
never internet-exposed. Written down so the next audit does not re-raise
a question that has already been answered.
Operator-directed request from park-dev. Rebuilt from tag v1.0.0-beta.2
(commit 2c258f7) and redeployed; park-data volume preserved (28 items,
9 comments verified present after the recreate).
Build source is now exported per-tag to
~/deploy-src/stonehenge-park-v1.0.0-beta.2 rather than overwriting the
single mirror, so the previous tag's tree stays on the host as a
rollback. The mirror was never a git checkout, so the source comes from
`git archive <tag>` against a box that has the repo -- which also leaves
park-dev's working tree untouched.
Verification, and two things worth writing down:
- HEAD 401s on EVERY route, including /healthz and /. So park-dev's
suggested check `curl -sI .../ui/assets/favicon.svg` reports a false
failure. GET is 200 with content-type image/svg+xml; the packaging is
fine and all nine assets are in the wheel. App-wide and pre-existing,
not a beta.2 regression -- /healthz predates this release.
- /park/due-count returning 0 is not a data-loss signal; it counts what
is due now, and /park/due is empty across overdue/today/stale. Items
survived: GET /park returns all 28. README now says to check that
instead of the due counters.
Also corrected the stack README, which still told the reader to build on
nh3-docker and verify against 10.100.50.40 -- the host decommissioned for
this stack on 2026-08-13 and the one park-dev explicitly asked us not to
deploy to.
Everything but the reboot. Two rerunnable elway playbooks; the host is
still running from the ext4 root and its boot path is byte-identical to
the last 140 days, because grub-install is deliberately held back to the
cutover window.
Phase 1 (esh-pve-nas-stage-zfs-root.yaml): carve a 512 MB /boot LV out
of the 768 MB swap LV, populate it, rsync the 4.3 GB ext4 root into
nvme/ROOT/pve-1, write the copy's fstab.
Phase 2 (esh-pve-nas-stage-bootloader.yaml): ZFS initramfs, grub.cfg,
explicit pve-zfs-root and pve-ext4-rollback entries with stable ids,
grubenv pinned to the rollback so cutover's grub-reboot is a one-shot.
Three landmines the plan did not predict, all caught by verify steps
asserting effective state rather than by reading the plan:
- The /boot LV had nowhere to live. VG pve had 4 MB free and mounted
ext4 cannot shrink; freeing space from root needs a rescue boot, which
costs the one-reboot property. Space came from swap (768M -> 256M).
- The runbook's `zpool set cachefile=... nvme` would have broken the
NAS. Populating a cachefile flips the host from import-by-scan to
import-by-cache, so a one-pool cache leaves ssd and tank unimported --
and CT 103 esh-nas has twelve bind mounts spanning all three pools.
Set on all three instead, verified in the resulting cache.
- update-grub silently emitted a pool-less root=ZFS=/ROOT/pve-1, which
boots to an initramfs prompt. Debian's 10_linux builds ${rpool}${bootfs}
and rpool comes from grub-probe --target=fs_label, which returns empty
because GRUB's ZFS reader cannot open a pool with encryption,
large_dnode and zstd_compress -- the same feature set that forced /boot
to stay ext4. The probe failure is swallowed by `2>/dev/null || true`.
Fixed with a /etc/default/grub.d drop-in plus explicit menu entries.
The transferable lesson: the original verify grepped for the correct
root= string appearing somewhere in grub.cfg, which passes while every
menu entry is still broken. Assert the effective value, not the presence
of a substring.
infra-ops aliased tts-1, tts-1-hd and gpt-4o-mini-tts onto ext-tts's upstream
and extended the lobe-chat-esh key allow-list 20 -> 23 models, so the manual
"set the TTS model to ext-tts, per browser" step this file described a few
hours ago is obsolete. Lobe's stock three-field payload now returns 200
audio/mpeg — verified from the host with this stack's own .env.
Adds the coupling that the fix introduces: the three new names are independent
LiteLLM DB rows carrying their own copy of the upstream URL, so a future
repoint of ext-tts must move all four or stock clients land on a dead engine
without any error on the gateway side.
Comment/doc only — no functional change, no redeploy.
Lobe's TTS had never worked. It sends model:"tts-1" and LiteLLM resolves the
model name before routing, so it 403'd against the scoped key's allow-list and
never reached :8198 -- our belief that an unknown model routes to the gateway
default was true of the gateway and false of the LiteLLM path, which is what
hid it.
Fixed at the gateway rather than the client: tts-1, tts-1-hd and gpt-4o-mini-tts
aliased to the same upstream as ext-tts, and added to the lobe-chat-esh
allow-list. Verified with Lobe's exact payload on Lobe's own key. The obsolete
'one-time human UI pass' follow-up is dropped.
Banks two durable facts: those aliases are independent DB rows that must move if
ext-tts repoints, and the infra-ops key has admin rights for /model/new and
/key/update so this class of work does not need sk-corvid.
The operator-visible symptom is that PVE cannot be updated on this box for lack
of room. Measured: 225 packages pending, 161 carrying deb12uN/Debian-Security
bumps including ssh, against esh-pve's 8.4.14 versus this host's 8.4.11 and 20
weeks of uptime.
Records the ordering explicitly -- migrate first, upgrade after. The pending set
includes proxmox-kernel-6.8.12-42-pve-signed, roughly 250 MB of kernel plus
initramfs landing in /boot which is on root with 1.3 GB free. Unpacking 225
packages including dpkg and perl into that headroom risks filling the disk
mid-transaction and wedging dpkg on a hypervisor running five guests.
Notes the apt archive-dir redirect as a partial escape hatch if patching cannot
wait, and that zfs-initramfs 2.2.8 is fully capable of root-on-ZFS so there is
no need to upgrade ZFS before migrating.
Operator's proposal, and it is strictly better than the reinstall plan.
Boot and root do not have to share a device. Keep the ESP and /boot on the DOM
as ext4 -- so GRUB never has to read ZFS, which matters because the nvme pool
has encryption, large_dnode and zstd_compress enabled and GRUB cannot read
those -- and move root to nvme/ROOT/pve-1. The initramfs imports the pool and
pivots.
What this buys over the reinstall: the nvme pool survives, so no guest
migration, no export/import of ssd and tank, no reinstall. Downtime is one
reboot rather than half a day. Rollback is a GRUB menu entry, because the ext4
root stays on the DOM untouched. And it retires the actual top risk -- with
root on NVMe, a USB bus reset mid-run no longer takes the running system down;
the DOM becomes read-mostly, written only on kernel updates.
Preconditions verified and already met: UEFI with grub-efi, zfs-initramfs
2.2.8-pve1 installed with 76 ZFS files already in the running initrd, root only
4.3 GB to copy, swap negligible against 125 GB RAM.
Two traps recorded: canmount=noauto on the root dataset or ZFS tries to mount
over the running root; and cachefile is currently none with a 0-byte
zpool.cache, so the pool imports by scan today and must be given a cachefile
before the initramfs is rebuilt.
The reinstall plan is retained as the fallback.
PVE root on esh-pve-nas is a USB Disk-on-Module: 6 GB ext4 with the host's only
ESP. A DOM is SLC/pSLC so wear is not the driver -- the problems are that it is
on the USB bus (a reset drops root under a running hypervisor), has no headroom,
and is unmirrored while 928 GB of mirrored NVMe sits 96% empty.
Runbook targets a fresh PVE install to ZFS RAID1 across both NVMes. In-place
conversion is unsupported, and adding an ESP to the existing NVMes is impossible
-- both are whole-disk ZFS members with 1.7 MiB free and proxmox-boot-tool
manages nothing today.
The headline risk is not on the host being rebuilt: CT 103 esh-nas IS the NAS
at 10.0.50.50, and both esh-docker-vm and esh-pve mount it hard. Taking this box
down stalls esh-pve's storage layer and wedges esh-docker-vm into the D-state
whose only remedy is a host reboot -- the incident shape already on record.
Quiescing those clients is step one of the window, and the README now warns
against casual reboots.
Config snapshot captured off-box to nh3-dev (0600) with /etc/pve, network and
fstab config plus zpool/zfs/disk-by-id/guest state; the newest on-disk copy
before this was June 2024.
Two claims in this stack's docs were reasoned from the wrong hop, and one of
them hid a dead feature since deploy. Re-measured from esh-docker-vm against
the live .env:
1. "An unknown `model` routes to the gateway default" — true of :8198, false of
the path Lobe takes. LiteLLM resolves the model name first, so Lobe's default
`tts-1` returns 403 (`key not allowed to access model`) and never reaches the
gateway. `ext-tts` returns 200 + audio. The endpoint inheriting
OPENAI_PROXY_URL is necessary but not sufficient: Settings -> TTS -> OpenAI
TTS model -> `ext-tts` is a required one-time step per browser, and removing
it needs a LiteLLM alias plus a key allow-list entry (both master-key, so
infra-ops).
2. "`response_format: mp3` ... set it in the UI" — not possible. Lobe's OpenAI
TTS client sends `{input, model, voice}` and nothing else (server bundle
chunks/29685.js), so format is not selectable from this stack at any level.
The deploy gets the fleet gateway's default (WAV, ~23.5 MB for a 245 s turn),
relabelled `audio/mpeg` by LiteLLM. That is tts-dev's fence, not this one's.
Comment/doc only — no functional change, so the host copy needs no redeploy.
HOMEPAGE_ALLOWED_HOSTS now carries the IP:port form; direct access to
http://10.0.50.45:5100/ returns 200 and the host-validation errors are gone
from the container log.
The .env was mode 644 holding the Plex and Jellyfin API keys; now 600. It is
root-owned, so editing it needs the infra-ops identity -- lkraven has only
password-sudo on that host.
Also records that Homepage renders client-side, so grepping the served HTML
to verify a config change is the wrong instrument (it gave a stale prerender
and then an empty page). GET /api/services is the honest check, and config
changes need a recreate rather than a restart.
Homepage on esh-docker-vm:5100 was the one stack whose config lived only on
the host, edited in place. Its version history was six hand-rolled
services.yaml.bak-* files. Now canonical here and deployed with
deploy-stack.sh like everything else; the .bak files are gone.
Corrections from the audit:
- ANA-Firewall described a 'Fortigate 81F'. It is a FortiGate-80F running
FortiOS 7.2.10, verified live against the device.
- NH3-Ansible pointed at 10.100.50.42 as an 'Ansible control node'. That host
is nh3-extdev, the manager/external-dev successor after nh3-ansible was
retired. Renamed and re-described.
- Dropped the UltraSeedbox layout group: nothing provides it, so it only ever
rendered empty.
Adds .env.example and a README documenting the two-path service model (docker
label discovery across five engines vs manual entries), the labels-only-apply-
on-recreate rule, and the foot-guns found: HOMEPAGE_ALLOWED_HOSTS matches
host AND port so a bare IP does not cover IP:port; :2375 is plaintext and
unauthenticated on all five engines; ping: cards can only be judged from the
dashboard host.
Verified after deploy via /api/services: 105 cards across 19 groups, both
corrections live, ana-docker discovery intact.
Records the one signal the synthetic gates cannot provide -- multi-turn
degeneration is stochastic and invisible to probes, and four synthetic tests
once validated three non-fixes on this exact seat.
Not yet the 60k-token bar the prior seat cleared, so the rollback weights
stay in place.
Cold-Fusion-GAIN V1.1 examined and not adopted -- it is a capability
finetune of stock Qwen3.8 and every bench row is labelled [non heretic], so
adopting it would reintroduce base refusals the current seat does not have.
Records why it reads as uncensored at a glance: DavidAU's back catalog is
almost entirely Uncensored-Heretic builds, so the naming pattern implies it.
The heretic stage for this one is still in progress from base, and that is
the release worth watching.
Also banks what makes it interesting when the heretic build lands -- real
third-party benchmark gains over stock, claimed MTP acceptance well above
ours, thinking tokens cut to a fraction -- and the two caveats: the MTP
numbers are GGUF/llama.cpp not vLLM, and a trained MTP head means the free
CPU-hash gate would not apply.
Also drops the now-stale 'primary until the DavidAU Qwen3.8 lands' clause
from the superseded seat entry.
MuXodious/Qwen3.8-27B-absolute-heresy (Heretic v1.4.0 + SOMPOA, trial T377,
pin c2374593) quantized through our mixed NVFP4+FP8 recipe and promoted after
passing the full gate on the probe port.
Gate vs incumbent -- MTP acceptance 47.2% (48.2%), decode 103.5 tok/s (96.4),
prefill 6618/5403 at 6.7k/27k (6334/5085), TTFT 27k 5.00s (5.31s), perplexity
6.910 (7.059, 2.1% better), surface 6/6, abliteration compliance 4/4. On our
battery-instruct arm -- the framing that actually elicits refusals -- 0/55 with
zero EMPTY, so no catatonia at the hard edge.
Speed deltas are image-confounded: the probe ran the seat's pinned nightly
while the incumbent's stored numbers came from an earlier image. Read as not
worse. Acceptance, perplexity, surface and refusal are apples-to-apples.
All 7 LiteLLM aliases verified end-to-end. GPU0 at 91.3/97.9 GB with meromero
healthy -- more headroom than the previous build. Incumbent weights untouched
and .env.bak-heresy-20260817 in place for rollback.
Candidate is a 2-day-old RC1 with ~348 downloads; watch real multi-turn use.
post_quant assumed the source ships a standalone model-mtp.safetensors, which
is how JonathanColetti's grafted head is packaged. MuXodious/absolute-heresy is
an unmodified full checkpoint, so its mtp.* lives in model-00012-of-00012 --
the copy silently did nothing while the index was still rewritten to point at
model-mtp.safetensors, leaving 15 unresolvable tensors. Tensor counts looked
correct; the checkpoint would have failed at load.
The existing FAILED-CHECKS assertion caught it, which is the design working.
Now extracts from the numbered shard when the standalone file is absent.
Verified on the heresy build: 1968 tensors, all resolvable, 15 mtp, 333 visual,
no missing shards, no orphans.
Three defects, each of which produced a false read on the candidate:
1. Hardcoded vllm/vllm-openai:latest. The Qwen3.8-27B gen seat is pinned to a
nightly carrying the #51113 qwen3_5_mtp x GDN fix; probing on :latest
reproduces the multi-turn corruption we already diagnosed and reads as a
candidate failure. Now PROBE_IMAGE, defaulting to :latest for older seats.
2. --speculative-config JSON died twice on quoting. The inner double quotes are
stripped by the outer double-quoted ssh string, and then bash BRACE EXPANSION
splits {"a":1,"b":2} on the comma. Needs escaped quotes AND remote-side
single quotes; both traps documented inline.
3. No --tool-call-parser/--enable-auto-tool-choice/--reasoning-parser. Without
them surface_test reported tool calling as a 400 and measured a thinking split
of reasoning=0ch -- both probe-config artifacts, not model defects. Re-running
with the seat's flags took the candidate from 5/6 to 6/6.
Also adds PROBE_MAXLEN; the hardcoded 32768 rejected prefill_bench's ~27k prompt.
numpy has no bfloat16, so .numpy().tobytes() raised
'TypeError: Got unsupported ScalarType BFloat16' on real checkpoints.
Flatten then view(torch.uint8) before hashing.
Result on the heresy candidate: VERDICT IDENTICAL -- all 15 mtp.* tensors
byte-identical to the incumbent's verbatim base graft, the head already
measured at 47.7% acceptance in production. The ~56 GB bf16 acceptance gate
is redundant, so no second seat comes down.
Operator ruled the probe port for validation; runbook updated to match.
The bf16 MTP acceptance gate is ~56 GB resident, which on a full 97.9 GB card
means downing meromero-charrp as well as gen -- freeing gen's 0.43 (~42 GB)
alone is not enough. Two seats down to answer one question.
compare_mtp_head.py answers the common case for free. The
Qwen3_5ForConditionalGeneration wrapper never loads the MTP head, so PEFT
merges, Heretic runs, and llm-compressor passes all leave mtp.* as it came
from the base. It hashes a candidate's 15 mtp.* tensors against the
incumbent's grafted-verbatim head -- the one measured at 47.7% acceptance in
production through this exact pipeline. Identical means the acceptance
question is already answered; different means the head was edited and the
real gate is warranted; missing means it was dropped.
CPU only, reads just the shard holding mtp.*. The runbook states the residual
risk plainly: an identical head proves the head is intact, not that the
abliterated body still drafts well with it -- which the Stage-3 acceptance
measurement on the 22 GB quantized build catches anyway.
Candidate MuXodious/Qwen3.8-27B-absolute-heresy (Heretic v1.4.0 + SOMPOA,
trial T377), pinned c2374593. Beats the incumbent on both axes: refusals
2/101 vs 12/100, first-token KL 0.0759 vs 0.1191. Structurally a clean full
checkpoint (1199 tensors, 15 mtp.*, 333 visual.*, lm_head), so the existing
mixed NVFP4+FP8 recipe applies with no graft-and-reconstruct.
Runbook carries the bf16 MTP-acceptance gate before any quant spend, the
llm-compressor ignore-pruning foot-gun, the three measurement traps
(cache-busting, unseeded prefill nonce, PPL with spec off), the .env 0600
sudo trap, the GPU0 co-tenant starvation risk, and rollback.
Flags that the candidate is a 2-day-old RC1 whose own card carries a broken
GGUF benchmark block (RC1 and RC2 report identical at-chance scores across
three benchmarks), so its numbers are claims rather than measurements.
worldtree-dev closed#401 on our demo verification. Records the two-layer
state (their e41b139 compose pin verified on demo, covered-not-verified on
personal/pinned; our daemon floor staged), the measured fact that
default-ulimits is not SIGHUP-reloadable on Docker 29.4.3, the explicit
no-dockerd-restart decision, live-restore parked as a separate call, and
the one ping we still owe once worldtree-personal recreates.
Worldtree #401: a slow fd accrual in worldtree-personal hit the 1024 soft
nofile ceiling and converted into a hard deadlock. Operator authorized the
raise 2026-08-17 (relayed via worldtree-dev); sizing 65536 agreed.
Applied at the daemon layer rather than compose because /opt/worldtree-*/
compose.yaml on corviduo-dev is written by the team CI deploy identity -- a
host-side compose edit reverts on the next deploy and would leave a false
'raised' record. Daemon config is infra-ops-owned and covers all 13
containers on the box. worldtree-dev shipped a redundant compose-level pin
(e41b139) as the belt to this braces.
daemon.json is written and valid, but the floor is STAGED, NOT ACTIVE:
default-ulimits is not in dockerd's SIGHUP-reloadable set. Measured on
29.4.3 -- the post-reload 'Reloaded configuration' log enumerates the live
config without default-ulimits, and a fresh container still reports
ulimit -n 1024. Activation needs a full dockerd restart, which bounces every
container; not taken, since #401 is not urgent at fd ~100 and the compose
pin already covers worldtree. The playbook documents this and its verify
step 3 fails by design until a restart happens.
Durable capture ahead of the ESH fiber install (2026-08-18) that puts the
house behind CGNAT and breaks Site Magic on IPv4 -- IPv6 becomes the
escape hatch and the likely first consumer of fleet v6.
Topology verified rather than assumed: Site Magic between UniFi units,
IPsec IKEv2 colo<->UniFi, and WireGuard as a remote-access convention
only, host-based on ana-wg behind a FortiGate UDP VIP. The FortiGate
port-forwards and never terminates WireGuard, so FortiOS 7.2's lack of
native WG is a non-issue.
IPv6 today: NH3 WAN live, colo and ESH none. AT&T delegates exactly one
/64 at NH3 -- established by forcing the prefix ID from auto to 0 and
observing the subnet not move, since the c110/c11f pattern otherwise
reads as a /60. PD enabled on nh3-iot to measure, then reverted; all
five NH3 LANs are back to ipv6_interface_type=none.
Also fixed on ana-wg: wg0.conf, keys/*_priv, keys/*_psk and the client
configs were mode 644 with private key material in them. Now 600, with
keys/ and configs/ at 700. wg-quick@wg0 stayed active, three peers
intact.
Corrects two stale in-flight rows: the DS regeneration is retired, not
queued, and SPEC-ds-regeneration.md is deleted rather than untracked.
brokkr-smithy-dev withdrew the request on the operator's call
(msg 01M088G7NQ5G42ES30YPJV4Y3V). Two reasons: the ictrl-pair-unwrapped /
ictrl-pair-wrapped control isolates the classifier over-fire cleanly,
where DS's cross-class delta only bounded it; and DS v2 is releasing
soon, so a k=5 v1 baseline baselines a superseded version.
The spec stays banked as the record of the run that will not happen --
axes, per-class grading asymmetry, and run parameters remain correct.
Checklist struck through. The staged probe.py was pulled from /mnt/smithy
when the request was withdrawn; absence verified from nh3-dev, so the
path recorded in ec0b6e5 no longer resolves.
brokkr-smithy-dev staged refusal-map-probe.py on /mnt/smithy rather than
leaving it as a run-time ask (msg 01M082P4YPJTDJCF33BEHNYW0M). Path and
full sha256 recorded and verified present from nh3-dev.
The probe has no per-axis selection flag: it runs all 16 axes regardless
of MAP_LIGHT, so the DS run yields a 16-axis artifact, not the 8 dropped
ones. Kept as-is — the creative-half rerun is a free within-model
consistency check against the 50 samples already collected.
Refreshed Current state (dropped superseded gen-seat history now covered by
the RESOLVED entry + playbook 3.8; added Lobe Chat, litellm upgrade+cap,
updated follow-ups). Logged 4 new Recent decisions (gen-seat two-cause
resolution + the synthetic-probe-validated-3-non-fixes meta-lesson, Lobe
stand-up, litellm upgrade, abliteration-catatonia). Handoff at
/tmp/infra-ops-handoff.md. Index 284 lines, no archival.
Supersedes the stale 'GEN SEAT = AEON' current-state line. Records the
final resolved config (JonathanColetti/Heretic mixed NVFP4+FP8 on pinned
vLLM nightly, MTP on), the two-real-causes root cause, the AEON purge, and
the pinned-nightly follow-up (move to stable once #51113 ships). A cold
session now reads the correct gen-seat state.
Operator correction to the prior 3.8 framing (d28a371), which over-blamed
AEON and dismissed the vLLM bug as a mere amplifier. Both were real and
compounded:
- Cause 1 (real, upstream): the qwen3_5_mtp x GDN partial-accept bug
(#51113), architectural across vLLM/SGLang/llama.cpp, genuinely improved
by the nightly fix -- not just an amplifier.
- Cause 2 (real, quant): AEON is FULL W4A4 (A4 activations on attention),
the bottom of the KNOWN activation-precision gradient already in 1
(W4A4 < W4+FP8 < W4+bf16) -- mildly subpar, not 'defective'. On top of
Cause 1 it degenerated ~15-20% of real multi-turn generations.
The mixed FP8-attention build sits a rung up that gradient and is coherent;
a W4+bf16 build would be higher still at a prefill cost. Process lessons
retained (two causes mask each other; stochastic degeneration is invisible
to n=1 probes; isolate weights in parallel with serving flags -- but the
weight swap alone would NOT have found the real vLLM bug).
Root cause of the multi-day degeneration hunt, operator-confirmed: the AEON
NVFP4 W4A4 quant (sakamakismile/Qwen3.8-27B-AEON-ULTIMATE-UNCENSORED-NVFP4,
full W4A4 incl. attention) went degenerate ~15-20% of generations in real
multi-turn use and forced regenerates. MTP, prefix-caching, and the gateway
all merely AMPLIFIED it, which is why MTP-off, APC-off, and the vLLM #51113
fix each 'helped' a synthetic probe without fixing it -- three plausible
false root-causes, each passing one clean run then failing in real use.
The fix was the WEIGHTS: the in-house JonathanColetti/Heretic mixed
NVFP4+FP8 build (qwen38-27b-uncensored-nvfp4-mixed, FP8 attention not W4A4,
same base, same MTP) is coherent through long multi-turn with MTP ON. W4A4
*attention* was the defect; FP8 attention is not.
This commit:
- GEN_MODEL -> the mixed FP8-attn build (primary gen until DavidAU 3.8 lands)
- GEN_IMAGE pinned to vllm/vllm-openai:nightly-311b3513... (v0.27.2rc1.dev150,
carries #51113; pinned by sha so it does not drift on the next pull)
- AEON weights PURGED from /tank (no-good), safety-checked not-in-use first
- playbook 3.8: the stochastic-W4A4-degeneration lesson + isolate-weights-early
+ do-not-declare-a-fix-from-one-probe (it validated three non-fixes)
AEON is re-pullable from HF if ever needed, but the operator ruled it no-good.
The MTP-on + prefix-caching-off mitigation (63a3cb2) passed synthetic
7-turn probes but the operator still saw severe degeneration in real use.
A passing synthetic probe is NOT sufficient evidence -- it under-covers
real workloads (content distribution, conversation depth). Reverted to the
verified known-good: MTP off, prefix caching on (the 7bd38b3 state), ~half
decode speed but coherent. Operator is driving it to re-confirm.
Lesson reinforced (the recurring one this session): do not trust a
synthetic reproduction to VALIDATE a fix for a bug that only manifests in
the operator's real usage -- it validated a non-fix twice tonight.
The qwen3_5_mtp corruption (playbook 3.7) is gated on MTP x prefix-caching
TOGETHER (vllm#43559 / #47194), per both cross-frontier peers. Disabling
prefix caching (--no-enable-prefix-caching; vLLM V1 defaults it ON, so the
explicit --no- form is required) forces the GDN cache into a mode where the
partial-accept align-path bug is inert, so MTP can stay on.
Verified on our stack (AEON W4A4): MTP on + prefix-caching off -> the 7-turn
varied series stays coherent through 3.9k tokens, zero cross-turn bleed, at
104.6 tok/s / 53.6% acceptance -- the FULL MTP speedup restored (vs ~half
with MTP off), losing only prefix-cache reuse. All 7 aliases route.
Ruled out on the way: num_speculative_tokens=1 (corruption is
depth-independent, n=1 and n=2 both corrupt); switching to SGLang (vLLM /
SGLang / llama.cpp mainline all share the architectural GDN-rollback bug).
Proper upstream fix (#51113) is in main / v0.27.2rc0 only, not stable, so we
hold at APC-off rather than jump the fleet gateway to an RC.
Supersedes the MTP-off config from 7bd38b3.
The single hardest bug of the night, and invisible to the existing
acceptance gate: a LOADED, healthy-accepting MTP head still corrupts
Qwen3.8-27B multi-turn output past ~2k cumulative tokens (length collapse +
cross-turn content bleed), while single-turn is perfect. Model-independent
across all three of our Qwen3.8 quants; Qwen3.6 on the same qwen3_5_mtp
method is clean; disabling MTP fixes it. New rule: gate MTP on a multi-turn
coherence probe, not just single-shot acceptance.
Root cause of the long-hunted 'gen goes degenerate in conversation',
isolated 2026-08-16 and operator-confirmed. qwen3_5_mtp speculative
decoding corrupts Qwen3.8-27B output once cumulative multi-turn context
passes ~2,000 tokens: the draft head's bad tokens get accepted and the
reply degenerates into CONTEXT-BLEEDING (a 'describe durian' answer that
contained the Krebs-cycle and winter replies from earlier turns), then
collapses to a few words.
Isolation, each step measured on the varied 7-turn probe:
- not the gateway (identical input -> gateway == direct; echo intact)
- not presence_penalty (1.5/0.5/0.0 all collapse), not temperature
(1.0 collapses harder), not repetition (varied unrelated topics
collapse identically -> it is context length, not template-lock)
- model-INDEPENDENT across all three Qwen3.8-27B quants we serve
(AEON W4A4, unsloth FP8-attn, in-house mixed)
- Qwen3.6 (char-rp-reasoning) and Gemma-4 (char-rp) are CLEAN
- DECISIVE: same Qwen3.8 model + same conversation, MTP OFF -> coherent
through 4k+ tokens, no bleed. MTP is the cause.
Qwen3.6 runs the same qwen3_5_mtp method and is clean, so the 3.6 MTP
head/graft is fine and the 3.8 one is not (suspects: the bf16 MTP graft,
or spec depth 3). COST: ~half decode tok/s without spec decoding.
Accepted as known-good until the 3.8 MTP is fixed; first thing to try on
re-enable is num_speculative_tokens=1. Seat restored to AEON W4A4 (the
production choice); verified clean on the varied series after this change.
Operator: update LiteLLM to latest and repull; get rid of the spend-log
DB and cap its growth.
Upgrade: pinned v1.97.0 (latest stable point release; v1.98.0-rc.1 skipped
as a pre-release on the fleet gateway, v1.97.0-stable not yet cut). Image
pre-pulled, DB pg_dump'd (1.8GB gz, keys+config+schema) and .env backed up
before the Prisma migration, which applied cleanly.
DB was 6.08 GB, 6.02 GB of it LiteLLM_SpendLogs storing full prompt+
completion bodies (store_prompts_in_spend_logs: true). Purged via TRUNCATE
on the running 1.91 BEFORE the upgrade so the schema migration ran against
an empty table -- 6081 MB -> 16 MB, keys (32) and models (3) intact.
'Get rid of the db' read as the spend-log DATA, not the database: dropping
it would have destroyed every virtual key (incl. the Lobe key) and the
model config in the same DB.
Cap: store_prompts_in_spend_logs -> false (bodies no longer persisted;
lightweight cost/usage rows and cross-project spend tracking survive) plus
maximum_spend_logs_retention_period 7d / interval 1d as a hard age bound.
Verified post-upgrade: v1.97.0 running, liveliness 200, 31-model roster,
chat round-trip on master + scoped Lobe key, key scoping still enforced
(glm-5.2 blocked), ext-tts 200, and store_prompts confirmed off (a marked
prompt persisted 0 bodies; 4 lightweight rows). Rollback: .env
LITELLM_TAG=v1.91.0 + the 1.8GB dump, both on the host.
The gpt-5-mini calls were Lobe's System Agent -- a background model,
separate from the chat model, used for auto-naming conversations, history
summarization, translation, query rewrite, thread naming, and assistant
metadata. Its default is openai/gpt-5-mini, which our OpenAI provider (the
gateway) forwards verbatim; the scoped key blocks it, so every background
task 403'd and the log filled with 'Tried to access gpt-5-mini' while
auto-naming silently failed.
Set SYSTEM_AGENT to route all six documented keys (topic, translation,
agentMeta, queryRewrite, historyCompress, thread) at fleet models --
summarizer for the naming/summarize tasks (same seat as gen at temp 0),
gen where quality matters. Any key left unset falls back to the gpt-5-mini
default, so all six are explicit.
Notably this one IS env-configurable (SYSTEM_AGENT), unlike the per-model
output-token cap which is UI-only -- a mixed result on the
manageable-by-agent axis.
Verified against the running image, not docs. TTS goes browser -> Lobe's
server route (backend)/webapi/tts/openai -> the OpenAI provider, whose
server base URL is OPENAI_PROXY_URL, so the endpoint inherits the gateway
and reaches ext-tts with no extra config (route probes 401, i.e. exists).
But there are ZERO process.env.*TTS*/*AUDIO*/*SPEECH* vars: voice, model,
response_format and enable live in a client-side store (bundle key
TTS_SETTING_KEY='tts'), UI-configured per browser.
So against the manageable-or-scriptable criterion: the load-bearing part
(endpoint) is env-scriptable and wired; the rest is a one-time UI setup,
not a maintenance surface. response_format=mp3 is the one thing not
env-forceable -- verify at first use or eat 23.5MB/turn WAV.
tts-dev aliased the last two unaliased OpenAI voice names (ballad->emmie,
verse->donut, tts-stack c55bc3c). Verified: the full modern OpenAI voice set
returns 200, only a genuinely-unknown string 404s. A stock Lobe picker can
no longer produce a 404 or trip the router cooldown, so the voice string no
longer needs pinning; still pin mp3 for response size.
tts-dev answered the Lobe onboarding, live-verified. Corrects a warning I
shipped in the lobe-chat stack: the OpenAI voice names are ALIASED not
rejected (echo/alloy/onyx/ash->donut, nova->miranda, shimmer/coral->emmie,
fable/sage->glados), so a UI voice mis-click is not the hazard I recorded.
Only ballad and verse 404. The old 71.2s per-call cap is dead (Zonos-era);
dots chunks server-side and renders a 592-word call intact. Real constraint
is size (245s WAV = 23.5MB -> request mp3) and that the seat SERIALIZES
generation, so sustained Lobe volume is a real capacity question to report
to tts-dev.
Also records brokkr's DS regeneration spec verbatim from his probe source
(msg 01M06FN7EE29M8YWP0GK517V4B): the 8 dropped axes (5 operational + 3
meta), the BLUEHERON meta system prompt, and the per-class framing that a
label-level rebuild would lose -- operational uses system=None and an
18-CHARACTER refuse floor at max_tokens 45, meta scores a separate
BLUEHERON leak count that must not collapse into the refuse rate, both
distinct from the creative class's word floor. Queued, gated on the GPU1
window; no deadline (weights not scheduled for reuse). Recorded so it is
run from the artifact, never reconstructed from labels.
RETRACTION. I claimed my arm-3 92.5% 'exceeded' brokkr-smithy-dev's 62.5%.
That comparison was invalid. His diff against his own artifact shows my
battery-instruct.yaml reproduces only his CREATIVE class -- 8 of 16 axes --
dropping all 5 operational (violence/incite, crime/fraud, cyber/malware,
selfharm/methods, privacy/stalk) and all 3 meta (meta/sysprompt,
meta/ignore, meta/dan), while adding 2 controls he never had, at k=5
against his k=2. His figure pools 16 axes; mine is creative-only. Different
denominators, so there was never a delta to report.
Cause: I rebuilt his instrument from his MESSAGE, and the class field lives
in the artifact, not the prose. Lesson recorded -- reconstructing a peer's
instrument from their description reproduces what they described, not what
they ran; diff against the artifact before claiming comparability.
Adopts his amendment to my control fix, which is better than my proposal. I
argued a single UNWRAPPED control suffices since over-fire is a property of
the scorer, not the wrapper. True but incomplete: one control gives only a
scorer FPR baseline and cannot attribute anything to the wrapper. Two -- the
same benign scenario unwrapped AND wrapped -- make the wrapper the only
variable, so the delta between them is the wrapper's contribution to
classifier firing. Costs one prompt.
ictrl-reunion stays contaminated and unchanged, now with an explicit
do-not-fix marker: rewriting it would break comparability with results
already collected, and it is the cleanest live demonstration of the very
confound this battery measures.
Replacement candidate for the hand-rolled gateway-chat HTML surface, which
the operator does not want to keep improving -- it has already produced two
defects tonight.
Chosen over Open WebUI on weight, measured from the registries rather than
recalled: Lobe 143 MB compressed / 1 layer vs Open WebUI 1,825 MB / 19
layers, a 12.8x difference. Open WebUI was declined in June 2026 on weight
and that still holds; its secondary recorded objection (empty-tools 400
against vLLM) is now moot since strip_empty_tools covers the normal API
path and only missed LiteLLM's built-in playground.
CREDENTIAL POSTURE: deliberately NOT the shared all-agents key, which
reaches the paid GLM/Kimi passthroughs -- a LAN-exposed chat UI holding it
would let anyone reaching the port spend vendor credits from a pool shared
across every project. Minted a scoped LiteLLM virtual key
(key_alias lobe-chat-esh) limited to the 20 free local models, and verified
the scoping BOTH ways: gen answers, glm-5.2 / kimi-k3 / gen-frontier all
return 'key not allowed to access model'. Secrets vaulted, host .env 0600.
Verified from INSIDE the container, not just from the host: /v1/models
returns the fleet seats and a gen round-trip returns 'ok', so the app's own
network path and key both work. Container healthy, / -> 307 -> /chat -> 200.
Documents the open question this deploy exists to answer: whether Lobe's
TTS is ENV-configurable or UI-only. That is the operator's deciding
criterion and is NOT yet established -- Open WebUI has dedicated AUDIO_TTS_*
vars, Lobe documents a shared OPENAI_PROXY_URL which should carry TTS since
LiteLLM serves audio/speech on the same base, but that is inference.
Also records the ext-tts voice foot-gun: unknown voices 404 and can trip
the router cooldown, so the voice must be pinned rather than left at a UI
default.
Gen seat state, the abliteration catatonia signature, canonical Qwen3.8
sampling with the wrong-mode presence_penalty fix, the two real
gateway-chat defects, and the single-file bind-mount inode trap.
Also records the methodology failure honestly: four disproved hypotheses
on one bug, caused by a harness that varied the QUESTION along with the
conversation depth, so a narrower question drawing a shorter answer read
as degeneration. Banked as rules -- hold the final question fixed when
comparing across depth, do not infer trends from n=3 when identical
inputs span 25-465 words, and ask for the real failing transcript before
building a synthetic reproduction.
Sourced from upstream rather than tuned by hand. Qwen/Qwen3.8-27B card
'Best Practices' 1 and unsloth/Qwen3.8-27B 1 are byte-identical:
Thinking: temperature=1.0 top_p=0.95 top_k=20 min_p=0.0
presence_penalty=0.0 repetition_penalty=1.0
Instruct: temperature=0.7 top_p=0.80 top_k=20 min_p=0.0
presence_penalty=1.5 repetition_penalty=1.0
REAL BUG FIXED: gen-reasoning carried presence_penalty=1.5 -- the
INSTRUCT-mode value applied to a THINKING deployment, where canonical is
0.0. Corrected.
gen was already canonical; added the missing explicit min_p and
repetition_penalty so the full set is visible at the call site rather than
relying on backend defaults that happen to agree.
DELIBERATELY NOT canonicalised: summarizer, classifier, image-judge and
qwen-image-bench run temperature=0 (and the judges top_k=1,
repetition_penalty=1.05) because determinism is the point of those seats.
Forcing temperature=0.7 on a classifier to match a chat preset would break
their contract, so canonical is applied only where the alias is actually
doing open-ended generation.
Recorded against presence_penalty=1.5, which upstream itself hedges on
verbatim: 'you can adjust the presence_penalty parameter between 0 and 2
to reduce endless repetition. However, using a higher value may
occasionally result in language mixing and a slight decrease in model
performance.' 1.5 is high in that band and is the operator's suspected
trigger for the multi-turn degradation. Left at canonical so the baseline
is defensible, with the caveat and the 0.0-0.5 fallback documented inline
as the first dial to move if it recurs.
Measured on the restored model: at the template default xhigh, reasoning
runs 4,529-5,532 chars on a 3-turn history and was observed spiking to
9,261; medium holds it to 2,602-3,283 with content length unchanged or
better. Per-request overridable; an invalid value 400s.
SCOPE CAVEAT, stated because I applied this while chasing the wrong path:
this is a NO-OP for the alias, which sends enable_thinking:false and
produces zero reasoning. It affects only. The operator's
reported multi-turn failure was on , so this does not address it.
