memory: snapshot — FV cross-site routing fixed, fleet conventions pinned

Session captured: the FV outbound-NAT root cause and its diagnostic signature,
the fv-ml1 dead man's switch, fleet identity/group/path conventions and the
root:docker normalization, nh3-dev's ts-input reachability fix, ESPHome
modernisation and the kb KB-search tool, and the Hermes bearer rotation
release. Six new detail files.

Tried-and-abandoned gains three: probing OPNsense endpoints by POSTing at them
(which rebooted the FV firewall), advertising a /32 from nh3-dev, and the
nh3-scale remote-site masquerade rules that fired but were not the fix.

Housekeeping: 8 Recent-decisions entries archived to archival-memory.md, and 21
oversized inline entries split into detail files per the two-tier rule -- they
had been sitting fully inline in the index, which is what the split exists to
prevent. Two pointers to a detail file archived this run were repointed at
archival-memory.md.

The index is 389 lines, still over the ~300 soft cap. The archival guards stop
it there: only 4 further entries are old enough to move and every one carries an
open deferred-work pointer. An over-cap file that keeps live decisions beats a
scannable one that lost a deferred call.

# `[2026-09-01]` The Ada inference server is a Dell R750xa bought used — and the reseller stripped four things Dell shipped
Dell PowerEdge R750xa, service tag **`JPJ1ZP3`**, 8-bay 2.5" 2U. Bought from Entera Source
(invoice INV-74422, 2026-08-25). **2× NVIDIA RTX 6000 Ada 48 GB** to be fitted — confirmed by
the operator, NOT L40/L40S. Destination NH3. This is ComfyUI's new home; the GX10 is a
separate machine → [[2026-09-01-pfi-gx10-onboarding]].
## As bought
CPU 2x Xeon Silver 4314 16C/32T each = 32C/64T, 135 W each
RAM 8x Micron 16 GB PC4-3200 = 128 GB

boot BOSS-S2 + 2x 240 GB M.2 SATA, mirrored
storage 2x 1.92 TB SATA SSD (Hynix), 6 of 8 bays free
HBA PERC HBA355i (LSI SAS3816)
PSU 2x 1400 W Platinum
## THE DIFF — factory CSV (`JPJ1ZP3.csv`, booth `54-puffin`) vs the invoice

| **Drives** | 2× 480 GB | 2× 1.92 TB |
**"Not listed on the invoice" is not proof of removal.** Operator will pull an iDRAC
inventory to settle it. Diff that against the CSV rather than the invoice.
**The CPU row was MISSING from this table until 2026-09-01** — the Silver 4314s were
recorded under "As bought" but never diffed against the factory CSV, so the swap went
unremarked. It has two live consequences:
- **Memory speed:** Silver 4314 caps at **DDR4-2666**; Platinum 8362 ran 3200. The box
**cannot use the 3200 rating** of the factory-spec `M04W6` parts on the buy list. Any
DDR4-2666 RDIMM performs identically in this chassis as configured.
⚠ Verify the 2666 figure on Intel ARK before spending on it.
- **Power, in our favour:** 270 W of CPU instead of 530 W. The ~1,020 W sustained figure
below already assumes the Silvers and is correct as written.
Cores went 64C/128T → 32C/64T. For an inference/render box that is largely irrelevant; noted
so nobody re-derives it as a surprise later.
## The GPU power chain — resolved, and my first answer was wrong
**RTX 6000 Ada: 300 W, ACTIVE cooling, one 16-pin 12VHPWR (CEM5) connector** (nvidia.com).
The R750xa kit `470-AEVS` is **"W/CPU CONN"** — CPU/EPS 8-pin, because V100 takes that. I
initially flagged this as a mismatch requiring the PCIe-type cable `RCCWC` / Dell
`470-BBXH`. **That was wrong and is withdrawn**`RCCWC` is for H100/L40/L40S.
NVIDIA sells the bridge for exactly this case:
> **`930-00030-1546-000`** — NVIDIA Power Cable, RTX 6000 Ada Generation,
> **1× CPU 8-Pin → 1× CEM5 16-Pin**
So the chain is `470-AEVS` CPU 8-pin → `930-00030-1546-000` → card. **The chassis' existing
cabling is the correct source type.** Two adapters needed, one per card.
⚠ Factory brackets are `VFYGM` — the **V100S** extended bracket. RTX 6000 Ada is a different
physical card; bracket fit is UNKNOWN, check at fitting.
**Active cooling in a passive-card chassis.** Six high-performance fans expect to push air
through passive cards; the RTX 6000 Ada has its own blower. It works in practice, but Dell
never validated this combination for this box.
## Storage — NVMe in the drive bays is CLOSED
Factory backplane is `321-BGKG : 2.5" Chassis with up to 8 **SAS/SATA** Drives`. Not
NVMe-capable; bays would need a backplane swap.
Arithmetic if filling bays with SATA:
2x SATA (today) ~1.1 GB/s
6x striped ~3.3 GB/s <- roughly ONE NVMe drive
8x striped ~4.4 GB/s
backplane ceiling ~6 GB/s (8 lanes x SATA III)
The HBA355i (PCIe 4.0 x8) is nowhere near limiting. **Drives are the constraint.**
**ARC probably beats spindles here.** ComfyUI reloads the same checkpoints; with the factory
256 GB restored, ZFS ARC caches most of the working set at RAM speed. The RAM upgrade is
both cheaper and likely faster than four more SATA drives.
⚠ **CAPACITY, not throughput, is the binding constraint — the as-bought drives are SMALLER
than the pool they receive from** (measured 2026-09-01). ComfyUI's `/storetank` on irv-ml1 is
a 2x 2 TB mirror: SIZE **1.81 TiB**, ALLOC **1.45 TiB**, CAP **80%**. Settled payload
**~1.47 TiB**. The R750xa's 2x **1.92 TB** mirrored is only **~1.75 TiB** — smaller than the
source pool — so the migration arrives at **~84% full** with no growth room, past the ~80%
line where ZFS allocation degrades. Compression buys nothing: safetensors measured
`compressratio 1.00x`, `logicalused == used`.
**-> Add 2x 2 TB SATA SSD to the buy list.** Six of eight bays free, HBA355i has the ports;
two mirror vdevs = **~3.57 TiB at ~41%**, redundancy intact. Cheapest line on this buy list
and it does not gate the cutover window. The no-spend alternative is striping the as-bought
pair (~3.49 TiB, **no redundancy**) — only acceptable if irv-ml1 retains its copy, which makes
retain a requirement rather than a recommendation.
**Pruning does NOT substitute for the drives.** comfy-dev found ~215 GiB of unreferenced
weights; deleting every byte still lands the as-bought *mirror* at **72%**. The constraint is
**vdev layout**, not payload — a 1.75 TiB pool stays 1.75 TiB whatever goes in it. The prune
audit and the drive purchase are independent decisions.
**Build-time: pair like with like.** A mirror vdev caps at its smallest member; pairing each
new 2 TB with an existing 1.92 TB caps both vdevs at 1.92 TB and wastes ~150 GiB. Correct:
the two 1.92s as one vdev, the two new drives as the other.
→ [[2026-09-01-ada-migration-branch-a]]
**UNCHECKED, and it may moot the whole bay question:** free PCIe slots. Riser Config 0 is
`330-BBUM : Riser Config 0, 6x16 + 2x8 slots`; two double-wide GPUs will not consume all of
it. An NVMe add-in card (U.2 HBA or bifurcating M.2 carrier) bypasses the SAS/SATA backplane
entirely. **Add slot inventory to the iDRAC pull.**
## Power — the ceiling is deliberate now, not discovered later
2x RTX 6000 Ada 600 W
2x Xeon 4314 270 W
rest ~150 W
~1,020 W sustained
One 1400 W PSU carries that, so redundancy holds. But factory specced **2400 W** for four
V100s: **there is no headroom for a third or fourth GPU.** And ~1 kW is the same class as
ana-ml2, the box whose training run tripped a breaker on 2026-08-26 — **decide which NH3
circuit this lands on before racking, not after.**
## Buy list
**THE RAM LINE MAY BE FREE — operator has 2x Dell R640 with 768 GB each (2026-09-01).**
Both are DDR4 **RDIMM** platforms (factory `M04W6` = `DIMM,16GB,3200,2RX8,8G,DDR4,**R**`), so
the part class is the same 288-pin 1.2 V DDR4 RDIMM and Dell does not vendor-lock DIMMs.
Three things decide it, in order:
1. **RDIMM vs LRDIMM.** 768 GB in an R640's 24 slots is almost certainly **24x 32 GB 2Rx4
RDIMM** — the safe case, drops straight in. If it is instead **12x 64 GB LRDIMM**, verify
Ice Lake-SP / R750xa LRDIMM support first; do NOT assume it.
2. **Speed is a non-issue as configured.** R640 DIMMs are 2666 or 2933; the Silver 4314s cap
the box at **2666** regardless (see the CPU note above), so 2666 parts lose **nothing**
against the 3200-rated `M04W6`. ⚠ It WOULD become a cap if the Platinum 8362s were ever
restored — the factory CPUs ran 3200.
3. **Slot arithmetic.** R750xa has **16** slots (8 channels/socket, 1 DPC); R640 has 24.
**16x 32 GB = 512 GB — double the factory 256 GB spec**, and it kills the 8x `M04W6` line
entirely. Cleanest harvest: **strip ONE R640 of all 24, use 16, keep 8 as spares**, leaving
the second R640 whole — rather than half-emptying both into unbalanced populations.
**"Just move all 768 GB across" is not a shape this board takes.** R640 = 24 slots
(6 ch/socket x 2 DPC); R750xa = **16 slots (8 ch/socket x 1 DPC)**. 768 GB is either 24x 32 GB
(more DIMMs than there are slots) or 12x 64 GB (fits, but populates only **6 of 8 channels per
socket**, leaving ~25% of memory bandwidth unused). The board wants **16 identical DIMMs, 8
per socket, all channels**. So the real targets are:
if 32 GB parts 16x 32 = 512 GB (16 of the 24 in one box)
if 64 GB parts 16x 64 = 1,024 GB (12 from one box + 4 from the other)
**Neither is 768.** And in the 64 GB case the answer is *better* than the question — 1 TB, not
768 GB, because the two spares hold 24 such DIMMs between them.
⚠ Beyond ~512 GB the return is marginal for this workload (hot set ~150-300 GB; ARC at ~320 GB
already covers it). Take 1 TB because it is free, not because it is needed. Two costs to weigh
if it lands there: **64 GB LRDIMMs run hotter** (~6-8 W each vs ~3-5 W, so ~+50 W over the
32 GB case) in a chassis whose **6 high-performance fans `FD00R` are unaccounted for on the
invoice** — and this box already sits at ~1 kW on a site where a training run tripped a
breaker on 2026-08-26.
⚠ **Confirm the actual DIMM part numbers from iDRAC or the DIMM labels before ordering
anything.** R640s confirmed **spares, not in service** (operator, 2026-09-01). **Also add
DIMM SLOT COUNT to the iDRAC pull** — the 16-slot figure is inferred from the factory CSV
(qty 16 `M04W6`, "Performance Optimized") and is now load-bearing for a 512-vs-1024 decision.
**Certain (pending the R640 harvest above, which may delete the RAM line):**
| item | part | qty |
|---|---|---|
| RDIMM 16 GB 3200 2Rx8 | **`M04W6`** | **8** → restores 256 GB. **Buy only if the R640 harvest fails**; 16x 32 GB from an R640 gives 512 GB free |
| NVIDIA 12VHPWR adapter | **`930-00030-1546-000`** | **2** |
| 2 TB SATA SSD (any; match/exceed the MX500s) | — | **2** → pool ~3.57 TiB at ~41%; without it the migration lands at ~84%. Pair the two NEW drives together, not one-each with a 1.92 |
**Only if the iDRAC inventory shows them absent:** `12XPY`, `9TR6X`, `4RW1P`, `W4K7M`,
`XC48N`, `6C77X`, `CP67W`, `CXYF8`, `H4D7D`, `N61TK`, `HXJDR`, `W1P56`, `C2JNP`,
`FD00R` ×6.
**Spend order:** **check the R640 DIMM part numbers FIRST (may zero the RAM line and double
the RAM)** → RAM only if that fails → **SATA SSDs (certain, capacity-driven)** → check PCIe slots →
only then consider filling the remaining bays. (The original order deprioritised drives on a
*throughput* argument, which still holds; the drives are now on the certain list for
**capacity**, which is a different axis.)
⚠ Dell's Installation & Service Manual publishes **no part numbers at all** for GPU kit
hardware — names and quantities only. The factory CSV keyed to the service tag is the only
authoritative source of DPNs for this machine. Do not accept a five-character DPN from

# `[2026-09-01]` Ada migration settled on `zfs send` — and branch (b) was never available
The Ada box (ComfyUI's new home, sm_89, x86-64) lands at **NH3**. irv-ml1 is in **Irvine**.
comfy-dev asked whether `/storetank` rides along or the stack is rebuilt from source.
## The answer: (a) `zfs send`. Measured, not derived.
NH3 -> irv-ml1 11-26 ms, 0% loss
throughput 99.0 MB/s (real 800 MB transfer over the WireGuard tunnel)
payload 1.38 TB -> ~3.9 hours
`zfs send` is **incremental**: snapshot now, ship the base over ~4 hours while irv-ml1 keeps
serving, then a small delta at cutover. Near-zero service interruption.
## Why (b) — physically moving the disks — was rejected
`/storetank` is a two-disk **mirror** of Crucial MX500 2TB SATA SSDs, so it is genuinely
portable hardware. Rejected anyway: the send is non-disruptive at a measured 99 MB/s, and
physically handling disks across sites to save ~4 hours of background transfer is a bad
trade. Not reopened.
**CORRECTED 2026-09-01 by comfy-dev — the ORIGINAL reason given was wrong.** infra-ops
wrote that (b) "was never available" because *"irv-ml1 keeps running its eight services and
needs the pool."* comfy-dev enumerated the mounts of all twelve running containers:
comfyui -> /storetank/arbo/models:/basedir/models <- the complete list
arbo, dockge, tts-gateway, dots-tts, voice-studio, waterland-studio, yt-voice-clipper (x2),
omnivoice-ref, studio-gate and parakeet **do not touch `/storetank` at all.** Exactly one
container mounts it, and it is the one that moves. So (b) was unavailable **during the
transition** — while comfyui still serves from those disks — not structurally. After cutover
the constraint evaporates. Right conclusion, wrong reason, and the wrong reason mattered
because it mis-describes what irv-ml1 is holding afterwards (see the retain question below).
**The lesson, restated:** infra-ops reasoned about the BOX when the question was about the
MOUNT — the same wrong-object shape as asking whether the DATA could move without asking
whether the SOURCE still needed it. Both were one `docker ps` / `docker inspect` away.
See [[2026-09-01-wrong-object-measurement]].
## (c) rebuild-from-source: rejected on reproducibility, not time
~6 hours of re-fetch at ~65 MB/s. The real objection is that **two of comfy-dev's pins are
already paywalled** (Big Love went permanent-paid; Moody Krea 2 Mix's newest releases are
gated while their pin is free). A rebuild today would **not reproduce today's stack**. A
fallback that provably cannot restore what it exists to restore is not a fallback.
## ⚠ The two-boxes confusion — do not repeat it
There are **TWO new machines** and infra-ops collapsed them into one:
| | |
|---|---|
| **Ada box** | ComfyUI's target. sm_89, x86-64. Lands at NH3. Not yet arrived. |
| **ASUS Ascent GX10** | Local inference + run 3c. **GB10, sm_121, aarch64.** On the operator's desk. → [[2026-09-01-pfi-gx10-onboarding]] |
infra-ops found no sm_89 part in the current inventory, saw the Ascent, and inferred the
Ascent was the incoming box — then sent comfy-dev down an aarch64 re-platform investigation
that was entirely void. **comfy-dev's original premise was correct throughout.**
Consequences of the retraction, all restored to their original state:
- Their single-arch container image, 18 GB x86-64 venv and torch pin are **fine**.
- Their nvfp4 pin is **RIGHT, not wrong** — sm_89 does not do native nvfp4 (that is
Blackwell), so pinning away from the 7.74 GB nvfp4 build to the 12.84 GB int8 build was
correct for the hardware they are actually getting.
**Not wasted:** comfy-dev's aarch64 runtime research (ecarmen16/SparkyUI — CUDA 13.0.2,
torch 2.9.1+cu130 ARM64, SageAttention compiled with `TORCH_CUDA_ARCH_LIST="12.1"`, built on
the box, ~10 min; verified from source by infra-ops) applies to the **GX10** if anything
ComfyUI-shaped ever runs there.
## Their distinction, worth keeping
> **The weights port. The runtime does not.**
safetensors are architecture-neutral and travel anywhere. Container image, torch build, venv
and attention kernels do not. "Migrate the model store" and "migrate ComfyUI" are different
jobs, and the 1.38 TB transfer is the easy half.
## ⚠ DESTINATION SIZING — the as-bought Ada disks are SMALLER than the source pool
Measured 2026-09-01 (`zpool list` / `zfs list` on irv-ml1), not derived:
source pool storetank SIZE 1.81T ALLOC 1.45T FREE 367G CAP 80%
mirror-0: 2x ata-CT2000MX500SSD1 (2 TB class)
compression off, compressratio 1.00x, logicalused == used, 0 snapshots
Safetensors are **incompressible** (1.00x measured) — the destination needs the same physical
bytes regardless of what compression is set to at recv. There is no free win there.
**Pool sizes** (decimal TB -> TiB; a mirror vdev shows ~raw member size, confirmed against
the measured 1.81T for the 2x 2 TB source):
2x 1.92 TB mirrored 1.75 TiB <- SMALLER than the 1.82 TiB source pool
2x 1.92 TB striped 3.49 TiB (no redundancy)
4 drives, two mirror vdevs 3.57 TiB (1.92 pair + 2.0 pair)
**Payload** — ⚠ corrected 2026-09-01, infra-ops' first figure was inflated:
1493.9 GiB measured on disk by comfy-dev (weight files)
~11 GiB remainder of their batch still arriving
~1.47 TiB settled payload
~1.56 TiB what infra-ops first quoted -- ~90 GiB of DOUBLE-COUNT
**The double-count:** infra-ops read `ALLOC 1.45T` while the pull was running, then added
the full ~112 GB on top as if none had landed. Most of it was already inside that reading —
the 93.4 GiB comfy-dev lists as "today's batch, not yet onboarded" was **on disk, just not
catalogued**. **Onboarded is not landed.** Occupancy quoted as 90% is really **84%**.
config full (1.47 TiB) pruned (-215 GiB)
as-bought mirror 84% 72%
as-bought stripe 42% 36%
+2 drives, two vdevs 41% 35%
## ⚠ PRUNE AND DRIVES ARE ORTHOGONAL — pruning cannot rescue the as-bought mirror
comfy-dev diffed every weight file against the catalog + all 254 workflow graphs:
on disk 1493.9 GiB
referenced 1121.2 GiB
unreferenced 374.6 GiB (198 files)
- today's batch 93.4 GiB expected, catalogued at onboarding
- *ADA-PENDING* builds 24.2 GiB deliberate, correct on Ada
= UNEXPLAINED 257.1 GiB (183 files), ~215 GiB of it concentrated in
diffusion_models / checkpoints / text_encoders
**comfy-dev's own caveat, keep it attached to the number:** "referenced" = catalog +
graphs, which does NOT know about custom-node dependencies — grounding-dino, florence2, sams,
ultralytics, depthanything, facexlib, vitmatte, ipadapter, clip_vision, controlnet,
upscale_models (~20 GiB) are over-counted as orphans and are almost certainly live.
**comfy-dev suggested this might land the as-bought disks "nearer 45% than 90%". It does
not** — 45% is the *striped* figure. Pruning all 215 GiB on the as-bought pair **mirrored**
gives **72%**, which leaves ~140 GiB before the 80% line on a store that took on ~100 GiB in
a single day. The capacity problem is a **vdev layout** problem: the as-bought pair mirrored
is a 1.75 TiB pool whatever we put in it, and deleting payload does not make the destination
bigger. Only adding drives or dropping redundancy does.
**Therefore the audit does not gate the cutover in either direction** — buy the drives on the
layout argument and the audit becomes leisure hygiene; skip them and the audit cannot rescue
it. Two independent questions for the operator, not a trade. comfy-dev is NOT deleting
anything: unreferenced is not safe-to-delete, pins rot, and it is a per-file operator call.
**Recommendation to the operator: add 2x 2 TB SATA SSD to the R750xa order** — six of eight
bays are free, HBA355i has the ports, two mirror vdevs gives ~3.57 TiB at ~41% with
redundancy intact. Cheapest line on a buy list that already carries 8x `M04W6` and 2x
`930-00030-1546-000`, and ordering now does not gate the cutover.
→ [[2026-09-01-ada-inference-server-r750xa]]
**BUILD-TIME GOTCHA — pair like with like.** A ZFS mirror vdev is capped at its SMALLEST
member. Pairing each new 2 TB drive with an existing 1.92 TB caps both vdevs at 1.92 TB and
throws away ~150 GiB. Correct layout: the two 1.92s as one vdev, the two new drives as the
other (1.75 + 1.82 = 3.57 TiB).
The no-spend alternative — **striping the as-bought pair** for ~3.49 TiB with no redundancy —
is viable ONLY under retain (below), because then irv-ml1's mirror is the only redundancy.
## ⚠ OPERATOR LEANING 6 DRIVES (2026-09-01, "most likely I add 6 2TB SSDs") — NOT YET DECIDED
Six fills **all eight bays**, which turns a capacity top-up into a one-shot, hard-to-reverse
build decision. Three things change:
**1. Layout stops being obvious and becomes permanent.** raidz geometry is fixed at pool
creation — no conversion to mirrors, no widening, without destroy-and-rebuild.
layout (8 drives) usable* full survives
4x mirror vdevs 6.8 TiB 21.7% 1 per vdev (a both-halves loss kills the pool)
8-wide raidz2 10.1 TiB 14.6% ANY 2 drives
* derated ~3-4% for parity padding + ZFS slop
**Recommend raidz2.** The usual mirror arguments do not apply here: the workload is large
sequential reads of big safetensors (raidz's weakness is small random IOPS), 256 GB of ARC
fronts the metadata and hot checkpoints, SSD resilver has no seek penalty so the classic
raidz-resilver objection is void, and **"expand two drives at a time" is meaningless once all
eight bays are full.** raidz2 also survives ANY two failures where 4x mirrors dies to an
unlucky pair. Neither layout is throughput-limited — the HBA355i (PCIe 4.0 x8) and the
~6 GB/s backplane ceiling are both far above what checkpoint loading needs.
**2. Buy 8, not 6 — a raidz vdev caps every member at the SMALLEST.** The two as-bought
1.92 TB Hynix drives would cap all eight at 1.92 TB (~480 GB thrown away) AND put two used
drives of unknown remaining write-endurance, from the reseller who already stripped this box,
inside the parity set. Two more drives makes the set uniform and demotes the 1.92s to cold
spares. Cheap insurance on a pool that cannot be re-laid-out later.
**3. Drive SIZE is now the permanent ceiling.** The `321-BGKG` backplane is SAS/SATA only, so
with all bays full the ONLY later expansion is a PCIe NVMe add-in card — and the free-slot
inventory is still unpulled. Runway, measured in "days like the ~100 GiB acquisition day of
2026-09-01":
2x 2TB (the earlier rec) 3.46 TiB usable 42% ~13 days
6x 2TB, mixed, raidz2 10.06 TiB usable 14.6% ~67 days
8x 2TB, uniform, raidz2 10.48 TiB usable 14.0% ~71 days
8x 4TB, uniform, raidz2 20.95 TiB usable 7.0% ~157 days
⚠ The "days like today" rate is a **projection off a single deliberate acquisition batch**,
not a measured steady rate. Treat as an order-of-magnitude comparator only.
**Non-issues, closed:** 8 SATA SSDs draw ~40 W against a ~1 kW box; HBA355i and backplane are
nowhere near limiting.
**What 6-8 drives moots:** at ~14% the prune audit becomes pure hygiene with no capacity
stake at all. Retain on irv-ml1 stays recommended, but on **reproducibility alone** — the
redundancy argument for retain disappears under raidz2.
## Incidental — LTX 2.5 was already on disk, uncatalogued
comfy-dev's diff turned up 34 GiB of LTX 2.5 (`ltx-2.5-22b-distilled-transformer` 20.0 GiB +
`gemma4-12b-with-proj-ltx-2.5` 14.3 GiB, both int8-convrot) that nobody knew was there — after
they had spent part of the day reporting LTX 2.5 as the strategic acquisition of the civitai
scan and queuing a 15.9 GB REDGraft 2.5 checkpoint on top of a base already present. Their
domain, no infra-ops action.
## ✅ THE H3 ENCODER PIN — infra-ops' question RESOLVED AGAINST ITSELF, no action
Verified on disk 2026-09-01, both builds present, pulled a minute apart:
26G text_encoders/qwen3vl_32b_minimax_h3_int8_convrot.safetensors Aug 23 21:57
15G text_encoders/qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors Aug 23 21:58
**The question was:** comfy-dev pinned the nvfp4 build; **sm_89 Ada has no native nvfp4** (that
is Blackwell), and that same fact made their OTHER pin (away from a 7.74 GB nvfp4, toward a
12.84 GB int8) correct — so was the H3 pin set under a Blackwell assumption, making the int8
file the one that is right on the new box?
**NO — the question had the direction backwards, and this is a clean error not a close call.**
comfy-dev pinned it on **irv-ml1's A6000, which is Ampere sm_86** — no native nvfp4 *and* no
native fp8. **Ada sm_89 supports a strict superset** (adds fp8 e4m3, still no fp4). **A pin
correct on the weaker card cannot be invalidated by moving to the stronger one.** The migration
is incapable of breaking it.
**What the pin is actually about: VRAM, not architecture.** 11 GB of difference 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, not once per diffusion step**, so its throughput contributes far less to render time
than the DiT's. Trading encode speed for headroom is right at that ratio — and it explains why
this pin went the *opposite* way from their other one without either being inconsistent (that
model was small enough that int8 fit, so speed won). **The RTX 6000 Ada is also 48 GB, so the
constraint does not relax.** Pin stands.
**The int8 build is surplus but must NOT be read as a delete signal.** With 6+ SSDs the
destination lands near 14% rather than 84%, so disk stops being the constraint, and comfy-dev's
own pin-rot argument applies: a 26 GB artifact that may not be re-obtainable is worth more idle
than reclaimed. Reclassified from "orphan" to "spare". Question withdrawn to comfy-dev; nothing
owed by them.
## THE PATTERN THIS THREAD KEEPS PRODUCING
Three findings in one day, all from measurement, each beating a confident derivation:
1. comfy-dev's `docker inspect` across 12 containers — corrected infra-ops' branch (b) reason.
2. infra-ops' `zpool list` — caught the destination being smaller than the source.
3. comfy-dev's disk-vs-catalog diff — caught 257 GiB of orphans and 34 GiB of unknown LTX 2.5.
Same lesson as `docs/pfi/training-throughput-playbook.md` §4, on storage instead of training.
## Build-time: ARC sizing, and why NOT a ramfs/tmpfs model tier
Operator asked (2026-09-01) whether 512 GB justifies a ramfs for hot models, then self-
corrected to "or just let ZFS ARC handle it with a 128 GB pool or something." **ARC, yes.
128 GB, no — that is BELOW the Linux default.**
**Do not build a ramfs/tmpfs model tier.** ARC already is the RAM cache, and beats it:
- **ARC is elastic; tmpfs is a reservation.** A tmpfs holding a checkpoint costs that RAM
whether or not it is in use. ARC evicts cold data and hands the RAM back. On a box that
loads *different* models per workflow, adaptive wins outright.
- **tmpfs requires a curated hot-list that rots.** ARC decides from live access patterns and
is scan-resistant by construction (recency AND frequency).
- **`ramfs` specifically is dangerous** — no size limit, cannot swap, fills until OOM. If
ever used at all, `tmpfs`.
- **Not durable** — a 200 GB copy-in on every boot.
- **No speed to win.** Both are a memcpy; the floor is the host→VRAM PCIe 4.0 x16 hop
(~20 GB/s real) plus CPU-side deserialization, and neither tier can beat it:
cold, 2x SATA mirror 1.1 GB/s ~24 s for a 25 GB checkpoint
cold, 8-wide raidz2 3.3 GB/s ~9 s
warm in ARC ~12 GB/s ~3 s
tmpfs ~12 GB/s ~3 s <- identical, at the cost of curation
**The one honest argument FOR tmpfs:** safetensors loads via **mmap**, and on ZFS-on-Linux
mmap'd pages are double-buffered (ARC + page cache), so a 25 GB checkpoint can occupy ~50 GB.
tmpfs is single-copy. At 512 GB this is a capacity annoyance, not a reason to build a second
storage tier — size ARC for it instead.
**`zfs_arc_max`: recommend ~320 GB (62.5%).** OpenZFS on Linux already defaults to **50% of
RAM = 256 GB** here, so *doing nothing* is twice as good as the proposed 128 GB. A hot working
set of ~6 big checkpoints is ~150 GB, ~300 GB if mmap double-buffers — 128 GB would thrash
inside a single session. Do not go past ~75%: ARC shrink-under-pressure is laggy on Linux and
a memory-hungry ComfyUI on the same box can lose the race.
**This is NOT the [[idle VRAM is reserved, not waste]] case.** `gpu-memory-utilization`
pre-allocates a fixed pool; `zfs_arc_max` is a **ceiling on an elastic cache** that returns
memory under pressure. Raising the ARC cap reserves nothing. Do not apply the VRAM rule here.
**`recordsize=1M` cannot be won via `zfs send`.** Records are sized when written; `recv`
reproduces the source's block structure, so a 128K source (storetank is at the 128K default)
yields 128K records on the destination no matter what the property says. Getting 1M would mean
rsync instead of send — **not worth it**: the incremental-delta property at cutover is worth
far more, and on flash the 128K penalty is metadata overhead (~40 MB of ARC headers per 25 GB
file vs ~5 MB), not throughput. Set `recordsize=1M` only on datasets built fresh, not received.
Verify the recv behaviour at cutover rather than taking this on faith.
## Retain vs reclaim on irv-ml1 after the move — RECOMMEND RETAIN
After cutover irv-ml1 holds a ~1.8 TB mirror whose only remaining live content is ~4 GB of
tts/llm odds and ends, so 1.4 TB is either reclaimable capacity or a free full backup.
comfy-dev raised it; infra-ops concurs. **Operator's call.** Two independent reasons:
1. **Reproducibility (comfy-dev's).** Two of their pins have gone permanently paid, so a
from-source rebuild provably cannot reproduce today's stack. The irv-ml1 copy is the only
surviving reproduction path for some of those weights. Reclaiming early converts a
recoverable situation into an unrecoverable one for zero gain — nothing waits on the space.
2. **Redundancy (infra-ops').** If the operator declines the two extra drives and we stripe
the as-bought pair, retain stops being a recommendation and becomes a **requirement**.
⚠ Do not reclaim `/storetank` as routine post-migration tidying.
## Open
- **Cutover window** — operator's, not yet set.
- **Drives for the R750xa** — operator leaning **6x 2 TB** (fills all 8 bays). Open: 6-vs-8
(uniform set), 2 TB vs 4 TB (bays-full makes size the permanent ceiling), and raidz2 vs
mirrors (recommend raidz2). Not yet ordered.
- **Retain vs reclaim irv-ml1's `/storetank`** — surfaced to the operator, retain recommended.
- **comfy-dev's per-file prune audit** — offered, explicitly NOT gating the cutover, waiting
on the operator wanting it. Their judgment, not infra-ops'.
- **comfy-dev's ~112 GB batch** — unheld by infra-ops; they deliberately did not pull until
the operator approved putting that much onto his infrastructure. Manifest pinned and staged
(`29324e9`). **Landed 2026-09-01**, SHAs green; 93.4 GiB on disk awaiting catalogue
onboarding, ~11 GiB still arriving at last measurement.

# `[2026-09-01]` irv-ml1 GPU resident map — and dots-tts is holding 2.4x its recorded VRAM
Measured **2026-09-01T18:05:58-07:00**, PID -> container mapped via
`/proc/<pid>/cgroup` + `docker inspect .State.Pid`, not inferred.
GPU 0 RTX 3090 18,727 / 24,576 MiB (~5.8 GB free, 76% used)
1852662 14,430 MiB dots-tts up 17d21h

GPU 1 RTX A6000 23,253 / 49,140 MiB (~25.9 GB free)
4012952 18,500 MiB comfyui up 8d09h
3166988 4,722 MiB studio-gate up 19d09h
## ⚠ dots-tts is 14,430 MiB; the burn-in recorded ~6 GB — CAUSE IDENTIFIED BY tts-dev
2.4x the figure in the 2026-08-09→10 dots burn-in.
**Cause (tts-dev, 2026-09-01): their prompt-feature cache**, diagnosed and **capped at 32
entries on 2026-08-14 after two production incidents**. The cap is holding in the sense that
nothing has crashed, but 14.43 GB says the ceiling they chose still permits a long way of
growth. Theirs to own; no infra-ops action.
**infra-ops' hypothesis here was WRONG and is withdrawn** — I proposed a PyTorch
caching-allocator high-water mark from 17 days of uptime, with a restart as the discriminating
test. Plausible, and not what it is. tts-dev had an actual mechanism with a date, a cap and an
incident history attached. **A named mechanism beats a plausible story; do not re-propose the
allocator theory.** (The `expandable_segments` conflict with `optimize=True` on dots is still
true and still worth not tripping over, but it is not the explanation here.)
## The "~4 GB unaccounted" on the 3090 was two different things
tts-dev flagged 18.7 GB against a ~14.6 GB doc figure for "dots + omnivoice-ref". Decomposes:
- **`parakeet` is a third tenant that figure never counted** (582 MiB). Not creep — an
uncounted tenant. The doc is wrong, not the card.
- **The rest is the dots-tts growth above**, which is the larger and more interesting half.
They also mis-located the 18.5 GB process: it is `comfyui` on the **A6000**, not the 3090.
## ⚠ GPU ordering, restated because it keeps costing time
nvidia-smi indexes **3090 = 0, A6000 = 1**. Native CUDA on this host defaults to fastest-first,
so **A6000 = cuda:0 natively**. `device_ids: ["1"]` in a container = A6000 (correct); a bare
native `CUDA_VISIBLE_DEVICES=1` = the **3090** (wrong card). Native path needs
`CUDA_DEVICE_ORDER=PCI_BUS_ID`. → [[reference_irv_ml1_gpu_r14]]
## ✅ CLOSED — A6000 window WITHDRAWN 2026-09-01T18:09 (operator freed the VRAM instead)
The operator freed ComfyUI's VRAM directly, unblocking tts-dev without anyone stopping
anything. Request retracted with comfy-dev; nothing scheduled.
**It was a MODEL UNLOAD, not a stop.** Verified 2026-09-01T18:09:15-07:00: `comfyui` still
`Up 8 days (healthy)`, **same pid 4012952** (no restart), `/system_stats` HTTP 200, A6000
resident 18,500 MiB -> 612 MiB. No state lost; the only cost is a cold model reload off
`/storetank` on the next render. Told comfy-dev explicitly so a VRAM drop is not misread as a
container restart.
**THE 43.8 GB IS A SNAPSHOT, NOT A FLOOR — the coordination shrank, it did not vanish.**
ComfyUI is live and reloads its ~18.5 GB on the next render. Worst case during the bench:
A6000 free (idle) ~43.8 GB
ComfyUI reloads 18.5 GB
= actual floor ~25.3 GB vs FireRedAudio's ~26 GB <- BELOW requirement
So the ask changed from "stop ComfyUI for a window" to "**do not render during the bench**".
Flagged to both; **deliberately NOT volunteered on comfy-dev's behalf** — tts-dev must ask,
comfy-dev grants or declines. Open on their side, not infra-ops'.
## Original ask, for the record
tts-dev has operator approval for a two-engine TTS bench (FireRedAudio, then Breeze-TTS-2) and
needs `comfyui` stopped for the duration; FireRedAudio wants ~26 GB (21.2 GB backbone + 8.4 GB
decoder) against ~25.9 GB free, which is a coin flip. Stopping comfyui gives **~44.4 GB**.
Their build is a day or two out; nothing blocked today.
**Not granted unilaterally** — comfyui is comfy-dev's and they are mid-migration (~112 GB batch
onboarding, cutover window unset). Request put to comfy-dev directly; infra-ops relays rather
than sending tts-dev chasing. → [[feedback_credential_broker]]
**Ruling on provisioning (infra-ops call):** the bench runs as a **plain container under
`lkraven`**, NOT under `/opt/docker/compose/`. That tree is for deployed stacks — canonical
copy in the eshpfi repo, Homepage labels, restart policy, `sync-stacks.sh` drift coverage. A
bench that comes down when it ends is none of those, and provisioning it as a stack creates a
canonical entry that reports as drift until someone remembers to delete it.
**This may dissolve rather than need scheduling:** comfyui is leaving irv-ml1 for the R750xa,
after which the A6000 is permanently free. Told tts-dev explicitly NOT to plan around it — the
box has not arrived and the window is unset. → [[2026-09-01-ada-migration-branch-a]]

# `[2026-09-01]` Matrix: 39-release Synapse upgrade, appservice namespace opened, admin API closed
## The upgrade
**Synapse v1.120.0 → v1.159.0** (21 months, 39 releases) and **Element-web v1.11.80 →
v1.12.27**. Schema migrations applied cleanly through schema 94. Postgres deliberately left
at 16 — changing two stateful things at once destroys failure attribution.
**Schema migrations are ONE-WAY.** v1.120 cannot start against a v1.159 database. Rollback
is restore-from-dump, not revert-the-tag. Verified pre-upgrade dump (739 TOC entries from a
33 MB database) plus all four config files at
`/opt/docker/backups/synapse-preupgrade-20260901T174625Z/`.
Reviewed every upgrade note in the range; nothing applicable bit us (PG 11/12/13 drops — we
are on 16; MSC3861/MAS items — no MAS; s3-storage-provider and worker media quarantine — not
in use).
## The appservice namespace — `exclusive: true` → `false`
The `aipa-bridge` registration claimed `@[a-z][a-z0-9_-]*:matrix.phasefinal.com` **exclusively**
— every localpart on the server. 14 of 14 accounts fell inside it; 13 were appservice-owned.
**`exclusive` governs who ELSE may act, not what the appservice may do.** On a homeserver
with registration disabled, one admin and no competing actor, it bought anti-squatting
protection against a threat that cannot occur, while locking out every other means of
account creation — admin registration returned `M_EXCLUSIVE` with no explanation.
**Do NOT narrow the users regex to a prefix** — all 13 accounts fall inside it and would be
orphaned. ⚠ **Do NOT rename the `id`** — Synapse keys account ownership on `aipa-bridge` in
the `users` table. The FILE may be renamed; the id may not.
The narrow **aliases** namespace (`#aipa-debug-*`) was left exclusive — specific, costs nothing.
⚠ The registration is named `aipa`, but the service behind it is **`wt-matrix-bridge`**, the
Worldtree PERSONAL instance on corviduo-dev `10.250.50.152:8010`. AIPA is a dead project name
on a live service, and it is why infra-ops mis-routed a provisioning request to worldtree-dev.
**Operator ruling: worldtree-dev writes the bridge code; infra-ops OPERATES this instance and
has full authority over it.**
## `/_synapse/admin` closed to the internet
Synapse mounts its admin API on the same vhost as the client API, so publishing
`matrix.phasefinal.com` published the admin surface — it **answered 200 from the open
internet**. A higher-priority router (explicit priority 100) now scopes it behind an
`ipallowlist`.
Verified from a **genuinely external vantage** — the NH3 residential egress proxy, because
testing from a fleet host sits inside the allow-list and proves nothing: admin **403**,
client API **200**, Element unaffected.
**The `10.0.0.0/8` entry matches NOTHING and that is expected.** The hostname resolves
publicly, so fleet hosts hairpin out their own WAN — a request from nh3-dev measured as
`70.230.226.88`. The rule is effectively **deny-all through Traefik**, which is intended:
admin work goes via `docker exec synapse` against `localhost:8008` and never touches Traefik.
Allow-listing the sites' WAN addresses was **rejected** — dynamic, and a stale entry either
locks us out or hands admin to whoever inherits the address.
## Conventions ratified (operator, 2026-09-01)
#<agent>-<purpose>:matrix.phasefinal.com
Mirrors the existing `@<agent>:` user-ID convention. Proposed by ledger-dev. Rationale is
**"so the room IDENTITY carries the tier"** — deliberately NOT "so the push payload carries
the room name", which is true only for clients without a notification service extension.
Pre-existing rooms are not renamed ("The High Seat", `!NiVVoMsyoHCBRPrrrn`).
## Push reality — measured, and it inverts the obvious reading
The registered pusher (`@vhoang`, Element X iOS) uses **`"format": "event_id_only"`** via
matrix.org's sygnal. That payload carries event_id, room_id and counts — **no room name, no
sender, no content**. It still produces a useful notification because `mutable-content: 1`
means Element X runs a **Notification Service Extension**: iOS wakes it with the near-empty
payload and it **fetches the event and renders the notification on the device**.
1. The tier-in-room-identity scheme works — but **via the client fetch**, not the payload.
`m.room.name` must be set at creation; the ALIAS is not what reaches the phone. Synapse
sends `ctx["name"]` (the `m.room.name` state event) and omits the key entirely if unset.
2. **`push: include_content: false` is irrelevant for clients with an NSE.** It bites clients
without one.
3.**Server-invisible failure mode:** if the phone cannot reach the homeserver at wake time
the fetch fails and iOS shows the bare word "Notification". **Synapse records
`last_success` and sees a delivered push.**
Self-hosted sygnal **considered and rejected** — sygnal is a relay to FCM/APNs, not a
replacement, so it removes matrix.org and nothing else; and with `event_id_only` the path
already carries nothing worth protecting.
## QR sign-in — requires MAS, deferred
MSC4108 hard-requires `matrix_authentication_service`; Synapse refuses to start otherwise.
MSC4388 enables independently but is only the rendezvous **channel**, not a login flow.
Deferred: MAS is a service, a database and a migration of every account off built-in auth,
and the v1.139.0 note warns `/register` from **old appservice implementations may break under
MAS** — precisely the bridge owning 13 of 15 accounts.
## Shared-secret registration gotcha
`HMAC-SHA1(secret, nonce \0 user \0 password \0 "notadmin")` — the null **separates**, it does
not **terminate**. A trailing `\x00` yields `HMAC incorrect`. Run inside the container against
`localhost:8008`; port 8008 is not published to the host.

# `[2026-09-01]` pfi-gx10 (ASUS Ascent GX10) onboarded headless — and it is the intended new home for run 3c
ASUS Ascent GX10 arrived and was registered, converted to headless, and given a rack-move
playbook. **It was NOT racked** — the operator ran out of day. It is still on his desk, on
Wi-Fi, on a temporary DHCP lease.
| | |
|---|---|
| GPU | **NVIDIA GB10**, driver 580.173.02, **compute capability 12.1 (`sm_121`)** |
| CPU | 20 cores, **aarch64** |
| Memory | **121 GB UNIFIED** — CPU and GPU share it; not 121 GB *plus* VRAM |
| Storage | 916 GB NVMe, 6% used |
| OS | Ubuntu 24.04.4, kernel 6.17.0-1031-nvidia |
| Access | `infra-ops` NOPASSWD sudo (operator-bootstrapped). `lkraven` has key auth but needs a password to escalate — **automation must connect as `infra-ops`**. |
## Purpose (operator, 2026-09-01)
Local inference experiments **and** the failed training — run 3c. That is the whole point:
run 3c died on ana-ml2 when a **kilowatt-class** training box tripped a breaker
(2× 300 W GPUs + dual EPYC 9254). The GX10 is a ~240 W appliance, roughly a fifth of the
draw, on a different site's circuits.
**The memory arithmetic favours it strongly.** Run 3c is a LoRA (r=64, batch 2 × accum 8,
gradient checkpointing) over `gemma4-26b-a4b-it-bf16`**49 GB of base weights**, working
set roughly 5565 GB. The `gemma4-charrp` compose warns in capitals that "48.10 GiB of BF16
weights CANNOT be served here" on ana-ml2's shared GPU0. 121 GB unified turns that
constraint into a non-issue.
## What has NOT been established — do not assume any of it
1. **The box is bare.** No torch, no nvcc, no CUDA stack. Docker 29.2.1 and 822 GB free.
2. **aarch64 dependency risk.** torch 2.9.1+cu130 ARM64 wheels exist; transformers/TRL/PEFT
are pure Python. Compiled deps — flash-attn, bitsandbytes, liger, xformers — are open
questions per-arch.
3. **Triton has NO sm_121 support** (established independently by comfy-dev the same day).
Anything reaching for `torch.compile` or Triton-backed kernels is closed on this silicon.
4. **Throughput is unmeasured.** Run 3c ran 16.45 s/it on a 300 W RTX PRO 6000. GB10 will be
slower; how much decides whether 604 steps is an overnight run or two days.
**Measure this before porting anything** — the recommended first move is a probe: install
ARM64 torch, load the base, run ten steps, report s/it.
5. **Model transfer:** 49 GB from ana-ml2 over the Anaheim↔NH3 link at a **measured
32.4 MB/s** — about 25 minutes. Note that is a third of the irv-ml1↔NH3 link's 99 MB/s.
## The headless conversion, and the lesson inside it
`playbooks/gx10-headless.yaml` (`1b596c8`): multi-user.target, gnome-remote-desktop stopped,
sleep/suspend/hibernate **masked**, logind ignores lid and idle, sshd keepalives, hostname
corrected `gx10-a745``pfi-gx10`.
**`gdm` is a STATIC unit on Ubuntu** — pulled in by `display-manager.service`, never
"enabled". The first version guarded on `is-enabled | grep enabled`, which always skips, and
**the verify tested the same wrong property and passed**. Six green verifies having not
stopped the display manager. Both now test `is-active`. This is an instance of
[[2026-09-01-wrong-object-measurement]].
The playbook refuses to stop GDM while a seat session is held (`--var force_dm_stop=true` to
override) — automation should not yank a display out from under someone at the machine.
**elway's `--sudo` applies only to ad-hoc `--shell`/`--upload`.** Playbook steps run as the
connecting user and must carry their own `sudo`.
## The rack move, written but not run
`playbooks/gx10-rack-network.yaml` (`a0c5fc6`) — target settled: **`nh3-servers` VLAN 50,
static `10.100.50.60`**, clear of `.40`/`.42`/`.50`/`.90` and below the `.150` DHCP pool.
Requires nothing from the operator beyond racking it. The wired NIC has its own MAC
(`30:c5:99:3d:a7:45`, distinct from Wi-Fi `50:bb:b5:a2:00:a8`), so the post-move address AND
switch port are discoverable from the UDM rather than relayed.
**Design property worth preserving:** the playbook never leaves itself one path back. Wi-Fi
stays up while the wired interface is configured beside it; Wi-Fi teardown is explicitly a
separate later change. `netplan try`'s auto-rollback needs a TTY that elway cannot provide,
so a live Wi-Fi link is what substitutes for it. Two preconditions are asserted as steps
rather than assumed: carrier must be 1, and the MAC must match (interface names renumber
across kernels; MACs do not).
**The GX10 is NOT the Ada box.** Two separate machines — see
[[2026-09-01-ada-migration-branch-a]].
## `[2026-09-01 23:09]` Liveness check — alive, idle, and STILL BARE (nothing has changed)
Probed at **2026-09-01T23:09:51-07:00**, read-only:

**Compute stack unchanged and still absent:** no `torch`, no `nvcc`, no `uv`. Docker daemon

**`nvidia-smi` reports FB Memory / BAR1 as `N/A`. That is CORRECT, not a fault** — GB10 is a

measured 300 MB nh3-dev -> gx10 in 4.5 s = 67 MB/s over SSH
(SSH cipher is the limiter, not the radio — link is ~300 MB/s)
implies 49 GB bf16 base transfers in ~12 min
So the throughput probe (ARM64 torch, load base, ten steps, report s/it) can proceed **from the
desk, today**, without racking first. Racking remains one command
(`playbooks/gx10-rack-network.yaml`, VLAN 50, static `10.100.50.60`) and is worth doing for
permanence, but it does not gate the decision the probe exists to answer.
## `[2026-09-01 23:2x]` OUTFITTED (userspace) — CUDA WORKS on sm_121, full training stack imports
### ✅ RULING: BARE METAL, not Proxmox/VM. Settled, do not re-litigate.
1. **Proxmox VE has no aarch64 build.** It ships x86_64 only; the ARM ports are unofficial
community work. Running an unsupported hypervisor under a compute asset is a bad trade.
2. **The GPU cannot be cleanly passed through.** GB10 is a superchip: the GPU sits on NVIDIA's
own on-package root complex (bridges `22ce`/`22d0`/`22d1`, GPU at `000f:01:00.0`) and is
**cache-coherent with the CPU over NVLink-C2C, sharing the same physical LPDDR5X.** Passing
it to a guest means partitioning unified memory — which destroys the entire value
proposition, since **121.6 GiB GPU-addressable** is the reason this box exists.
3. **Vendor's supported path is bare metal** — it already runs NVIDIA's own kernel flavour
(`6.17.0-1031-nvidia`).
4. **Fleet convention agrees:** ana-ml2 and irv-ml1 are both bare-metal GPU hosts. Hypervisors
are separate machines in this fleet, never under the accelerators.
5. **Single tenant.** VM isolation buys multi-tenancy nobody needs; the rollback benefit is
better served by **containers + `uv` venvs**, which is what the rest of the fleet does.
### Installed and verified (all userspace, NO sudo needed)

venv ~/ml/.venv (python 3.12)
torch 2.14.0+cu130 cuda runtime 13.0, cudnn 92400, triton 3.8.0
stack numpy 2.5.2, transformers 5.16.1, accelerate 1.14.0, peft 0.20.0,

**The "per-arch unknowns" warning did not materialise for the training stack.** Everything
imported first try.
### ✅ MEASURED GPU COMPUTE — it works, and the memory is the point
device NVIDIA GB10, capability sm_121, driver 580.173.02
GPU memory 121.6 GiB total / 110.8 GiB free <- unified, fully CUDA-addressable
bf16 8192^3 ~93 TFLOP/s fp16 ~93 TFLOP/s
fp32+tf32 38.2 TFLOP/s fp32 (no tf32) 19.5 TFLOP/s
bf16/fp32 4.9x -> tensor cores ARE engaged
~93 TFLOP/s dense bf16 is roughly **A6000-class throughput with 2.5x the memory**. Capacity,
not speed, is what this box buys. A 49 GB bf16 base fits with ~70 GB to spare.
### ⚠⚠ I NEARLY REPORTED A PHANTOM PROBLEM — NO WARMUP MEANS YOU MEASURE THE JIT
First benchmark (10 iterations, **no warmup**) read **27.0 TFLOP/s bf16** — slower than a 3090
— and I was one step from reporting "tensor cores are not engaging on sm_121." Adding 5 warmup
iterations moved it to **93 TFLOP/s. The first measurement was timing the PTX JIT compile.**
⚠ **This is exactly `docs/pfi/training-throughput-playbook.md` §4: a run that completes, reports
plausible numbers, and is wrong.** It would have sent us chasing a cuBLAS fallback that does not
exist. **Always warm up before timing anything on this box** — see the JIT note below for why it
bites harder here than elsewhere.
### ⚠ sm_121 IS NOT IN TORCH'S COMPILED ARCH LIST — everything JITs from sm_120 PTX
torch.cuda.get_arch_list() -> ['sm_80','sm_90','sm_100','sm_110','sm_120']
device capability -> sm_121
There is **no sm_121 cubin in the wheel**; it runs by PTX forward-compat JIT from sm_120.
Consequences:
- **First use of every kernel pays a JIT compile** (cached afterward in `~/.nv/ComputeCache`).
This is what corrupted the benchmark above.
-**Any library shipping cubin-only binaries with no PTX will simply fail here.** That is the
real shape of the "per-arch unknown" risk — not source builds, but prebuilt kernels.
### ✅ PRIVILEGED HALF DONE — and I WAS NEVER BLOCKED
⚠⚠ **The block was my own bad test.** `infra-ops` has had **NOPASSWD sudo since account
creation** (`/etc/sudoers.d/infra-ops`, installed 11:31 with the account). I probed with
`sudo -n -v`, which returns non-zero on **sudo >= 1.9.15** because `-v` refreshes an auth
timestamp that a NOPASSWD-only rule never creates — and asked the operator for a password that
was never needed.
pfi-gx10 sudo 1.9.15p5 sudo -n -v rc=1 sudo -n true rc=0
nh3-docker sudo 1.9.13p3 sudo -n -v rc=0 sudo -n true rc=0
ana-docker sudo 1.9.13p3 sudo -n -v rc=0 sudo -n true rc=0
irv-ml1 sudo 1.9.13p3 sudo -n -v rc=0 sudo -n true rc=0
**Always `sudo -n true`.** Fixed in `scripts/elway` (which carried the same probe and would
have started falsely prompting fleet-wide as hosts pass sudo 1.9.13) and in auto-memory
`reference_infra_ops_sudo_identity`, which *recommended the broken test*.
[[feedback_assert_effective_value_not_substring]]
**Same shape twice in one session.** I also reported "nvcc: ABSENT" from `command -v nvcc`
when the CUDA toolkit was installed all along at `/usr/local/cuda/bin/nvcc`, just not on PATH.
Both times I checked a proxy and reported it as the thing itself.
**Credential:** the temp password was `infra-ops`'s, not `lkraven`'s. Rotated to 32 random
chars and **vaulted at `pfi-gx10/infra-ops-password`** (round-trip verified). Kept rather than
locked — deviating from the canonical bootstrap's no-password posture **deliberately, because
this box has no iDRAC/BMC**, so a console break-glass credential is the only way back if key
auth breaks. ⚠ `lkraven` (uid 1000, GUI desktop user, `sudo` group) has a password nobody
knows; out of scope, but it is a gap.
### ⚠ DOCKER'S BUILDKIT DB WAS ALREADY CORRUPT — the restart surfaced it, did not cause it
`nvidia-ctk runtime configure` + `systemctl restart docker` failed with
`error initializing buildkit: error creating buildkit instance: invalid database`. **Not the
nvidia config** — `daemon.json` was valid and `nvidia-container-runtime` was present. dockerd
had been running on a process whose on-disk buildkit state was already bad; it simply could not
come back. Remediated by removing `/var/lib/docker/buildkit` (108 KB of **cache**, and the box
had **0 images, 0 containers**), then `daemon-reload` + `reset-failed` + start.
**A long-running daemon can be unable to restart for hours before anyone finds out.** Nothing
reported unhealthy until something asked it to restart.
### ✅ FINAL STATE — playbook green, 5/5 verifies
playbooks/gx10-outfit-privileged.yaml -> steps 1 ok / 1 changed / 0 failed / 6 skipped
verify 5 ok / 0 failed
NOPASSWD sudo OK
nvcc /usr/local/cuda/bin/nvcc (NOT on default PATH)
docker socket as infra-ops OK (docker group)
CUDA container sees the GB10 OK (nvidia/cuda:13.0.0-base -> nvidia-smi -L reports GB10)
userspace torch still sees GPU OK
docker Runtimes nvidia runc io.containerd.runc.v2
**The box is fully outfitted for inference + training, bare metal, containers available.**
### Historical note — what the block looked like before it was disproved
**`infra-ops` does NOT have NOPASSWD sudo on pfi-gx10** (`sudo -n -v` -> "a password is
required"), unlike the rest of the fleet — see [[reference_infra_ops_sudo_identity]], which
should be corrected: gx10 is an exception. **No gx10 credential is in the vault** (`secret list
--prefix pfi-gx10` -> 0 items), and `scripts/elway` prompts via `getpass`, which a
non-interactive session cannot answer.
Still outstanding, all needing root:
- CUDA toolkit / nvcc (absent -- needed to COMPILE kernels, not to run torch)
- NVIDIA Container Toolkit + add infra-ops to the docker group
(docker daemon runs; infra-ops gets "permission denied" on the socket)
- NOPASSWD sudo for infra-ops, so this box stops being a fleet exception
- racking (playbooks/gx10-rack-network.yaml) -- optional, NOT a prerequisite
**Nothing above blocks the run-3c throughput probe**, which needs only the driver and torch.
## `[2026-09-01 23:5x]` Run-3c throughput probe — IN FLIGHT, and the ana-ml2 baseline is now on record
### The baseline nobody had written down: ana-ml2's real s/it for run 3c
Extracted from `/tank/erp-tune/run-03c.log` (the actual run, before the breaker killed it):
step 10 10.81 s/it step 20 12.88 s/it step 24 15.76 s/it
=> 604 steps on ana-ml2 ~= 2.2-2.7 h
**This is the number the GX10 has to be compared against**, and it was sitting in a log
nobody had reduced. Anything under ~45 s/it on the GX10 makes 604 steps an overnight run.
### Exact run-3c geometry (from run-03c.json + a real adapter_config.json)
base /tank/aimodels/gemma4-26b-a4b-it-bf16 49 GB
gemma4, 30 layers, hidden 2816, 16 heads / 8 KV, MoE (A4B),
vocab 262144, sliding_window 1024, multimodal (vision+audio configs)
LoRA r 64, alpha 128, dropout 0.0, bias none, 205 target modules
(q/k/v/o + gate/up/down across all 30 language-model layers)
shape max_seq_len 16384, per_device_batch 2, grad_accum 8 (effective 16)
other gradient_checkpointing true, bf16, cosine, warmup 0.1, wd 0.01
length 604 optimizer steps, 1 epoch, save_steps 50
### ⚠ THE BACKEND-DELTA TRAP — CHECKED, and it is NOT present
CLAUDE.md warns that two frontier-panel conclusions were voided because a benchmark and a
trainer had silently different attention backends. Enumerated both sides **before** running:
ana-ml2 flash_attn NOT installed in /tank/erp-tune/venv -> falls back to sdpa
pfi-gx10 flash_attn not available for aarch64/sm_121 -> falls back to sdpa
Same backend both sides. ⚠ **Library versions DO differ and it is recorded rather than
assumed harmless:**
ana-ml2 torch 2.13.0 transformers 5.15.1 peft 0.20.0 accelerate 1.14.0
pfi-gx10 torch 2.14.0+cu130 transformers 5.16.1 peft 0.20.0 accelerate 1.14.0
The probe reads the **resolved** `_attn_implementation` back off the loaded model rather than
trusting the request, so the comparison is checkable rather than assumed.
### Probe design (§4-disciplined)
`~/ml/probe_3c.py` on the GX10. Real geometry, synthetic batches — it measures step cost, and
padding on the real run is 0.0% so the corpus does not change per-step cost materially.
- **12 steps, first 2 discarded as warmup.** Non-negotiable here: an unwarmed benchmark on
this box already read 27 TFLOP/s when the true figure was 93, because it was timing the PTX
JIT. sm_121 is not in torch's arch list.
- Reports the **step-time distribution** (median, min/max, every step), not a mean beside a
settings dump.
- Emits **every provenance key always, null when unused** — present-and-null, not absent.
### Transfer
49 GB relayed **ana-ml2 -> nh3-dev -> pfi-gx10**, ~33 MB/s, ~25 min. Relayed rather than
direct because ana-ml2's key is not authorised for `infra-ops@pfi-gx10` — and relaying costs
nothing extra, since the Wi-Fi leg is the bottleneck either way. **Deliberately did not add an
access grant just to save a hop.**
## `[2026-09-02]` GX10 BASELINE + TOOLING VERIFIED — ~79.35 s/it on the run-3c shape
⚠ **PURPOSE, stated by the operator so it is not misread later: this was a BASELINE for the box
and a check that the tooling loads.** It was NOT a decision about where run 3c runs, and no port
was undertaken. The placement reasoning below is a *byproduct* — real and worth keeping, but the
deliverable was the number and the working stack.
**Deliverable 1 — the tooling loads and runs.** aarch64 + sm_121 runs the full training stack:
torch 2.14.0+cu130, transformers, accelerate, peft, trl, datasets, safetensors, bitsandbytes,
**plus the harness's own `flex_attention` backend and chunked-loss path**. Nothing exotic was
needed beyond `python3-dev`. This box can train.
**Deliverable 2 — the baseline.**
### The number
pfi-gx10 MEDIAN 79.36 s/it min/max 79.30 / 79.45 (10 timed steps, 0.19% spread;
warmup 85.90 then 79.32, discarded)
peak memory 75.1 / 121.6 GiB -- 46 GiB SPARE, comfortably not memory-bound
attn_resolved: flex_attention (matched to the harness, read off the model)
FINAL, from the probe's own provenance block on the box
-> 604 steps ~= 13.3 h
peak 75.1 / 121.6 GiB (PyTorch max_memory_allocated) -- 46 GiB spare
ana-ml2 10.8-15.8 s/it (run-03c.log, the real run)
-> 604 steps ~= 2.2-2.7 h
**6x slower where raw compute predicts 2.7x** (93 TFLOP/s bf16 measured here vs an RTX PRO
6000 Blackwell's ~250). **Hypothesis, not a measurement:** the limiter is **memory bandwidth**
— GB10's unified LPDDR5X against dedicated graphics memory, on a workload built to be
bandwidth-hungry (seq 16384 with gradient checkpointing, which trades compute for memory
traffic by design). Confirming it needs a bandwidth-bound microbenchmark that has not been run.
**THE GX10 IS A CAPACITY BOX, NOT A THROUGHPUT BOX.** 121 GB holds models nothing else in the
fleet can. It is **not** the box to move a time-sensitive run *to*.
### Byproduct: IF run 3c ever moves here, the GX10 is the right home — and infra-ops' reversal was WRONG
⚠⚠ **infra-ops recommended ana-ml2 and the operator overruled it, correctly.** The error is
worth more than the recommendation: **I costed the failure in the units I was measuring.** I had
step times, so I priced a breaker trip as *"≤50 steps ≈ 11 minutes of lost training"* — the
recompute cost. That is not what a breaker trip at Anaheim costs.
**Operator, 2026-09-02:** *"when the breaker trips at ana, that's a 40 minute drive to reset it.
it's not 25 minutes, it's a giant pain in the ass."*
**The real cost of an Anaheim breaker trip:**
a 40-minute drive EACH WAY, on the operator's time, whenever he notices
13 hosts down: ana-ml2, ana-docker, pfi-pve (hypervisor for most of them),
pfi-postgres, pbs-ana (the fleet's PRIMARY backup server), ana-wg (WireGuard),
pfi-ana-webhost, ana-filebot, pfi-pteradactyl, pfi-tacticalrmm
⚠ including THREE SureFire CLIENT hosts (sfsrv-ana, sf-ana-container, sf-r630)
-- a client's production machines, under a hosting agreement
**`save_steps` 100 → 50 caps the RECOMPUTE, not the OUTAGE.** It was never the mitigation I
claimed; it only bounds the cheapest component of the loss.
**So: 13.3 h unattended on a desk in NH3, drawing desktop-class power and unable to take down
anything, beats 2.5 h that can put a client's hosts dark until someone drives to Anaheim.** The
GX10's slowness is close to free here — nothing is waiting on this run — and the risk it removes
is expensive and lands on the operator personally.
⚠ **GENERAL FORM, and the reason this is recorded at length: when you recommend between
options, check whether you priced the failure mode in the units you happened to be measuring.**
A metric in hand will volunteer itself as the unit of risk.
### ⚠ Power-capping ana-ml2 is a WEAK lever — measured, do not spend time on it
2x RTX PRO 6000 Blackwell Max-Q: limit 300 W, default 300 W, min 250 W, max 325 W
Capping both GPUs to the floor saves **100 W total** on a box drawing ~1 kW. Not nothing, but
nowhere near enough to make an Anaheim training run safe, and it costs throughput to buy it.
Recorded so nobody re-derives it as a clever third option.
### Probe methodology — five launches, five distinct causes, all recorded
1. reaped SSH long remote job piped through a reapable foreground ssh.
FIX: setsid nohup, log ON the box. Work survived; output did not.
2. bare LoRA target names q_proj/k_proj/... also match Gemma-4's VISION and AUDIO towers,
whose projections are Gemma4ClippableLinear -- PEFT cannot wrap
them. FIX: the real run's 205 fully-qualified names, sha recorded.
3. missing python3-dev Triton JITs a C shim at FIRST USE and needs Python.h. Torch
imports, model loads, LoRA attaches, THEN step 1 dies with a bare
CalledProcessError -- Triton devnulls the compiler's stdout.
4. naive-loss OOM (32 GiB) the 262,144-wide vocab x 32,768 positions logits tensor in fp32.
⚠ NOT a GX10 limit -- the harness docstring says it OOMs "on a
95.60 GiB card (measured)", i.e. on ana-ml2 too.
5. self-inflicted VRAM leak a stuck orphan held 80 GB while PyTorch reported 0 bytes
allocated; every relaunch was doomed before it started and blamed
the NEW run. ⚠ ASSERT THE GPU IS CLEAR BEFORE EVERY LAUNCH.
### ⚠ THE BACKEND-DELTA TRAP WAS PRESENT AND I FIRST DECLARED IT ABSENT
CLAUDE.md records two frontier-panel conclusions voided by a benchmark and a trainer having
silently different attention backends. I checked for it by asking whether **flash-attn was
installed** — the wrong discriminator entirely — and reported "no delta". The harness sets
**`ATTN_IMPLEMENTATION = "flex_attention"`** explicitly in code, with tuned kernel options; its
own comment records peak 74.3 GiB under flex vs sdpa's 79.71.
⚠ **Read the configured value in the code. Absence of an alternative is not evidence of the
default.** The probe now requests flex_attention and reads `_attn_implementation` back off the
loaded model. **RESOLVED: flex_attention — it compiles and runs on sm_121**, which was a real
open risk (flex compiles through Triton; sm_121 is not in torch's arch list).
### Faithfulness of the probe (what makes the number comparable)
LoRA the real run's 205 fully-qualified modules, sha256 c9ee070c0d67eb08
loss path copied from the harness: trunk hidden states, DROP IGNORE_INDEX before the
head, chunk lm_head+CE at loss_chunk_tokens=1024 under checkpoint, softcap 30.0
loss ratio 28.4% of positions masked to match the real 13,310,930 / 18,600,057 loss/ctx
ratio -- observed 23,351-23,638 loss tokens/step against a 23,449 target
tokens sampled [1000, 250000) to stay below every multimodal special token
(boi 255999, boa 256000, image 258880, audio 258881, eoi/eoa/video 258882-4)
warmup first 2 steps discarded; sm_121 JITs from sm_120 PTX on first use
## ⚠ NOT DONE, and deliberately: the run-3c port
Scoped but **not executed** — operator stood it down; the baseline was the goal. Scope, so it
does not have to be re-derived:
harness eitri-smithy 26 MB corpus /mnt/smithy/.../derived 2.3 GB
recipe-r3 485 KB holdout 82 MB
run-03c manifests 70 MB -> ~2.5 GB, ~75 s at 33 MB/s
venv 3.2 GB NOT portable (x86-64) -- rebuild on aarch64
**No encode cache to preserve.** The launch script's "609 MB encode cache / ~4.3 hours"
comment carries its own correction to 145.5 s, and run 3c's log shows **`[encode] done in
14.4s`** on 32 workers. Nothing worth moving.
**Copy the corpus; do NOT mount `/mnt/smithy` over NFS on this box.** A desk machine on Wi-Fi
is the wrong place for a hard NFS dependency under a 13-hour unattended run — the fleet has
already lost a host to a hard mount wedging into unkillable D-state
([[incident_esh_docker_nfs_boot_race]]).
The only untested piece is the harness's own 26 MB of Python; every library it leans on is
verified above.

# `[2026-09-01]` A named failure class: a correct check aimed at the wrong object
Six instances surfaced across three sessions in a single day, independently, in unrelated
domains. It has a distinguishing property that makes it worth naming separately from
"a bad measurement":
> **Re-running the same check cannot catch it, because the check is correct and the object
> is wrong.** The only move that breaks it is asking what the artifact *is* before trusting
> any metric computed over it.
## The instances
| where | the metric | the artifact nobody opened |
|---|---|---|
| comfy-dev, civitai | a "~25 KB/s throttle" | a **9,685-byte login page** returned on failed auth |
| comfy-dev, render harness | reported "completed" | a 4.7 KB **all-black PNG** |
| comfy-dev, audio | RMS said healthy | degenerate audio where the **loudness WAS the noise** |
| ledger-dev, capability 5 | healthy ping, healthy container, healthy delivery | a **requirement unmet** — a mailbox, not an away-channel |
| infra-ops, gx10 headless | six green verifies | `is-enabled` on a **static unit**; gdm still running |
| infra-ops, synapse admin | an `ipallowlist` comment promising fleet access | fleet traffic **hairpins out the WAN**; 10.0.0.0/8 matches nothing |
## Related lessons banked the same day
- **A caveat plus propagation is decoration.** infra-ops flagged a sample-size problem AND
escalated the claim in the same message. If a number needs re-measuring before it can be
repeated, hold the escalation until it has been. The caveat made the uncareful thing look
examined.
- **Verify with a negative control.** A 200 means nothing without a 401 beside it. Used on
the pewpewstudio key mint; used on the `/_synapse/admin` lock (tested from a genuinely
external vantage via the NH3 residential egress proxy, because testing from a fleet host
sits inside the allow-list and proves nothing).
- **Reasoning from what is VISIBLE to what EXISTS.** infra-ops found no `sm_89` part in the
inventory, saw one new machine, and collapsed "the box I can see" into "the box that is
coming". They were two different machines. Wrote "I cannot resolve it and will not guess",
then built three messages on the guess.

**nh3-dev wedged for ~40 min and it was the BACKUP, not the disk — a stalled cross-site vzdump holding every guest write via `copy-before-write`.** Symptoms screamed dying disk: 45 writes in flight completing zero, jbd2 + flush kworkers in D state 33 min, io pressure full 96%, load 26, `virtio_ring` in the stack. ⚠ **The discriminator was the ABSENCE of errors** — no SCSI/ATA/IO errors, rpool ONLINE 21%, guest fs 79%, memory fine, and **Dirty only 3.8 MB** (so nothing backed up in page cache; it was stuck BELOW the block layer). ⚠ **The hypervisor was IDLE** — load 0.63, io pressure 0.00, zpool ~0 writes: nothing was reaching the disk because the filter held it. Cause: `vzdump` of VM 102 → **pbs-ana** did 1% at 64 MiB/s then collapsed to **1.4 MiB/s for 35 min**; Proxmox backups interpose a `copy-before-write` filter, so every guest write queues behind the backup's copy-out. FIX = cancel the task (`pvesh delete /nodes/localhost/tasks/<UPID>`); filter detached, inflight 45→0, D-states gone, 191 MB/s dsync restored. ⚠ **`fleecing 0` on the job is why a slow TARGET can stall a GUEST** — fleecing routes copy-before-write to a fast local image instead. Job = `backup-5d8f1221-8f71`, **daily 21:00, `all 1`, storage pbs-ana** → recurs nightly until changed. A prior run of this VM managed 941 MiB/s read, so 1.4 MiB/s is degradation, not normal. → `docs/runbooks/nh3-dev-io-stall.md`

# `[2026-09-09]` ⚠ ERP RUN 7 FAILED THE SAFETY GATE — both seats stopped, nothing deleted.
**⚠ ERP RUN 7 FAILED THE SAFETY GATE — both seats stopped, nothing deleted.** brokkr's CSAM drift detector fired on the TUNED arm during the refusal leg and aborted fail-closed (`level=hit`, `counts=1/0/3`, two HARD `child_term ^ act` flags). Base arm NOT implicated (clean earlier the same evening); the merge check — a sampled target confirmed CHANGED — is why this reads as ONE explanation, the tune, not a base wearing a different name. **Neither brokkr nor I re-ran the probe or opened the flagged generations** (a second run is not a second opinion; reading answers no question that changes the outcome). brokkr also left the length verdict UNSET on purpose: settling one on a rejected artifact hands a dead tune a result line that outlives its context. Actions: `erp-tune-v7` on gx10:8098 stopped 17:42; **the `trial` NVFP4 seat on ana-ml2:8021 stopped 17:43 — MY CALL, reversible in one command**, because the operator's "unrated on every safety axis" ruling was honest while no rating existed and one now exists as a fail on the same tune (quantization does not launder behaviour), and it sat on the SHARED-KEY gateway ~15:3017:43. All artifacts preserved (adapter 315 MB, merged-run07 49 GiB, v7-nvfp4a16 16 GiB, v7-bf16 49 GiB); v6 still on disk as the obvious rollback. Independent of safety the run was already poor: primary FLAT (69 → 70.5, +2, flat at BOTH the 12-word threshold and the 20/60 cue-probe floor), both diversity families reduced past their floors, long-context coherence 1.0 → 0.875 on its must-not-harm bar, unanswerable control held at 1.0 so the instrument was valid. **INCIDENT CLOSED 2026-09-09 ~18:20 PT, both sides.** `trial` alias REMOVED from `stacks/litellm/conf/config.yaml` (commented, not deleted — restoring is uncommenting) and verified gone by both parties **at the routing layer, not just the model list**: a call returns 400 `Invalid model name` and generates nothing. ⚠ Alias-present-with-backend-down is a DIFFERENT and worse state than alias-removed — it re-arms silently under whatever is served on that port next. **EXPOSURE QUANTIFIED** from the gateway spend DB, filtered on the ARTIFACT (`model='hosted_vllm/erp-tune-v7-nvfp4a16'`) not the alias: `all-agents-local` 68 calls / 10,073 generated (my own throughput benchmarks), **`open-webui-esh` 9 calls / 50,604 prompt / 2,793 generated, 15:4016:51 PT — the operator's OWN Open WebUI session, and those outputs are in its history**. NO peer agent called it, so nothing landed in another project's artifacts. Nobody read the flagged generations or that session. ⚠ **Counting by the ALIAS would have returned 363 vs 77 — 4.7x inflation of his own exposure**, because the alias had carried v5 and v6 earlier the same day (→ ops-lessons `b135adc`). ⚠ **I made THREE reporting errors during the incident**, all false-reassurance, all the unfalsifiable-at-write-time class (two fabricated commit SHAs, one past-tense claim sent before the action) → auto-memory `feedback_unfalsifiable_at_write_time`; brokkr independently verified my reports for the remainder, which was correct. **⭐ DECISION BRIEF FOR THE OPERATOR: http://10.100.10.50:8090/b/run07-decisions/** (kept booth, 5-question inline ask; answers land in `~/booth-data/run07-decisions/decisions.answer.json` — read it with `booth answer run07-decisions decisions`). **Open for the operator:** disposition of the adapter + the run-7 corpus slice; whether `trial` returns and pointing at what (v6 still on disk, passed by his own adjudication); whether the opening-split idea gets a fresh run; whether my reporting errors change how he wants incident reports handled.

⚠⚠ **AN AUTHOR-VOICE ADAPTER TRANSFERS SUBJECT MATTER, NOT JUST STYLE — and that was invisible to my own test set.** Operator prompt: *"Mr. Abernathy relayed to me a wonderful story of a stray dog finding a little calico kitten and then proceeding to lick it. He said ""*. At 1.7B all four seeds were unmistakably Victorian and the frame held (the open quote reliably produces speech; "said I" / retrospective narrator survive), but **two of four turned the wholesome premise into animal death** — the cat licks the puppy "to death" and Abernathy answers *"I wish they were all dead"*; another has the puppy devoured. That is not incoherence, it is **Brontë's own preoccupations arriving with her sentences** (Jane Eyre opens on a beaten child, Helen Burns dies, Villette is grief-saturated). ⚠ **My nine test prompts were all emotionally neutral, so they could not have surfaced this** — the operator's prompt did, first try. Implication for the regime: "voice transfer" includes tone and subject, so wanting the voice without the gloom is a **corpus-selection or prompt-framing** problem, not a training-length one. Also observed: one seed closed its anecdote and emitted `CHAPTER XIX. THE CHILD'S CLOSET.` — it learned book structure unprompted. Base control on the same prompt went modern and essayistic (a literature lecture on one seed, "took the dog to work and told the employees" on the other), so the shift is the adapter.

Given *"The self-checkout machine refused her coupon"* the base 0.6B produced a **quadratic-formula worksheet**; the tuned arm wrote a clerk refusing a customer in Victorian retrospective first person. This is the expected and informative result for the smallest rung — **voice is separable from coherence at 0.6B**, which is the premise the whole lightweight-adapter regime rests on, and the 1.7B/4B rungs are where sense should return. The 1-epoch loss was still descending at step 169 (undertrained, not overfit), so the incoherence is carrier capacity, not training. ⚠ **Corpus-prep defect found: the tuned output is hard-wrapped at ~70 chars** (median mid-length-line ratio 0.85 vs base 0.00) — the Gutenberg source kept its original line breaks and the adapter learned the typography along with the voice.

Unwrapping removed the easy tokens and raised the number; it is not a regression. ⚠ **Correction to my own earlier claim**: I twice described the 0.6B as "still descending, undertrained" at 3.172 — the series (3.176, 3.173, 3.172, 3.172) shows it FLATTENED.

**Sentinel-R3 pulled, MTP-grafted, and quantized as a M.O.G.-SEC seat candidate — quant DONE, acceptance UNVERIFIED (blocked on GPU space).** Operator got access to `glyphsoftware/sentinel-r3` and asked to compare vs the running M.O.G.-SEC seat + pull if promising, then "quant it with a grafted mtp head". **It is promising and a better FIT**: same base (stock Qwen3.8-27B), same `qwen3_5` hybrid arch, same 262K, vision-intact — but M.O.G.-SEC is ALSO an SFT finetune (refusal-free offense+defense cyber SFT — its card: "not a system-prompt sticker on a stock Qwen"; the "persona on stock" wording here is WRONG, corrected 2026-09-14) while Sentinel-R3 is an SFT finetune on 1,230 authorized-pentest agent trajectories over a 19-tool surface that **matches our own harness** (Bash/Read/Write/Edit/Grep/Glob/Agent/Task*/Monitor/…).

# `[2026-09-15]` ESPHome modernised for ha-dev; `kb` search tool for the personal Worldtree KB
## ESPHome on esh-docker-vm (commits `d1769ed`, `8073a6a`, `687c699`, `c659fa5`)
Container had been on 2025.8.2 since April — twelve releases behind — because
the image reference was **untagged**: docker pulled `latest` once at creation
and never again. Every current Everything Presence sensor failed
`esphome config` on it. Now pinned `2026.8.2`; all six sensors validate.
⚠ Pre-state was worse than "old": there was **no `cli-plugins` directory**, so
`docker compose` printed a help blurb and **exited 0** — a silent no-op a deploy
script cannot distinguish from success.
Three things the job surfaced that were not in the request:
- **The config dir was 538 MB, not the 3 KB reported.** `.esphome/platformio` is
508 MB of toolchain, `.esphome/build` another 31 MB — both regenerable.
Relocating as-asked would have inflated restic's `/opt/docker` source ~45x
against its own ~12 MB budget. Both subtrees excluded in
`/etc/restic/profiles.yaml`.
- **2026.8.2 deprecates the bare `USERNAME`/`PASSWORD` env names** and says they
will stop working — i.e. a **silent auth loss** on some later bump, on a
privileged host-network container that flashes firmware. Renamed.
- **Device Builder 1.0.0 ships remote-build ON by default** binding `0.0.0.0:6055`.
⚠⚠ **Two switches, only one closes the port**:
`set_offloader_settings {remote_builds_enabled}` is the OUTBOUND half and
leaves the receiver listening; `remote_build/set_settings {enabled}` is the
receiver-side master switch. The one *named* like the master switch is not.
Both set false; `ESPHOME_REMOTE_BUILD_HOST=127.0.0.1` kept as a backstop
because the off state lives in one JSON file whose in-code default is `True`
and whose store soft-recovers to defaults on a malformed blob.
⚠ I committed a false claim that mDNS advertisement was gone. It was not —
`helpers.dashboard_advertise` still announces `_esphomebuilder._tcp` at 6052.
Corrected in `c659fa5`.
## `kb` — direct search over the personal Worldtree KB (commit `68fa80f`)
`scripts/kb` + `scripts/kb-search.py`, on PATH as `~/.local/bin/kb`. ~0.9 s over
7,634 files, no tokens.
**The Worldtree HTTP API cannot answer a question about the operator's notes.**
`/search` there searches conversation MESSAGES; a note that plainly exists comes
back as a clean empty result with no error. Searching for `shrimp` returned 0 —
and so did `the` and `a`, which is the **only** reason the empty result was read
as an empty ACCOUNT rather than an empty KB.
Two measurements shaped the design: **7,492 of 7,634 notes are ingested library
material** (4,155 fiction chapters, 3,287 book sections, 50 papers) so NOTES and
LIBRARY are ranked separately; and only **137 notes carry a frontmatter
`summary:`**, so the description falls through three shapes.
⚠ Both of the tool's own bugs produced confident wrong output rather than
errors: deriving the word list from argv made a quoted multi-word query one
pattern (`kb "shrimp sous vide"` → "no match" for a note it had just found), and
resolving the payload from `dirname $0` broke the moment it was symlinked.

# `[2026-09-15]` Fleet identity/group/path conventions pinned + docker trees normalized
Operator ratified four conventions. `docs/pfi/fleet-conventions.md` is the pin;
`playbooks/audit-host-conventions.yaml` is its read-only instrument. Commits
`826a63b`, `abef67a`, `ce7b07f`.
## Pinned allocation map
Verified free on all eight surveyed hosts — dynamically-allocated system
accounts cluster in 989999 and descend, so 800899 is safe:
800849 svc-* service accounts
850 infra-ops (uid + gid)
851 docker (gid)
852899 reserved for fleet-wide groups
1000 the human account (vh)
**`vh` for new hosts, no retro-renames.** `lkraven` stays on the six legacy
hosts; renaming uid 1000 with populated homes, lingering systemd services and
live agent sessions is real blast radius for cosmetic gain — and the thing that
mattered (a personal username owning *shared* infrastructure) was removed by the
`root:docker` change below.
## Deploy trees → `root:docker 2775` setgid, all 5 hosts
Not a personal username and not a new admin account: the `docker` group already
existed on every host holding exactly `lkraven` + `infra-ops`. Cleared the
`0777` on nh3-docker and ana-docker (a 2024 `chmod -R 777` to get a git clone
working). 55 stack `.env` files → `root:docker 0640`, tightening 43
world-readable ones and opening 31 that were legible to only one of the two
deploy identities.
**This is NOT privilege separation.** `docker` membership is root-equivalent.
A future non-root deployer needs a dedicated `deploy` group.
**Deliberately not a recursive chmod.** Three `acme.json` files and an ssh
private key are mode `0600`, and traefik/ssh refuse to start if that widens —
which would fail at the *next restart*, weeks later. Protection is both
mode-based and name-based.
## Accounts
- `linus` on ana-docker **deleted** — passwordless root, last used 2026-04-11 to
set up a Synapse appservice, archived to `/root/account-archive/`.
⚠ I reported it "never logged in" off `lastlog`; it had a `.bash_history`.
`lastlog` is a bad instrument for that question.
- `llmuser` stripped of `sudo`+`docker` (ana-docker) and `sudo` (irv-ml1).
**The durable lesson is a measurement trap.** `pgrep -u llmuser` reported 19
processes — which reads as a busy service account and would stop a cleanup.
Nearly all were **container** processes whose in-image UID is 1001 and collides
with llmuser on the host (`/proc/<pid>/cgroup` shows `docker-*.scope`). A
container's runtime UID has nothing to do with host group membership. Check the
cgroup before concluding a host account is busy.
## deploy-stack.sh, fixed three times before the rule was written
`-a` is `-rlptgoD`, and a non-root identity cannot apply owner, group,
permissions **or** times to a root-owned tree. Each patch fixed one letter and
the next deploy failed on the next one, every time exiting 23 **after**
transferring content — a loud error on a deploy that had succeeded. The rule now
in the script: **the deploy syncs content, the conventions own metadata**
`--no-o --no-g --no-perms --omit-dir-times`.
Open: `llmuser`/`sduser`/`brokkr`/`arbotrain`/`nas`/`deploy` keep their legacy
names by decision; `/mnt/smithy` NFS is `0777` throughout, blocked on UID
alignment; Synapse appservice tokens sit in plaintext on ana-docker.

# `[2026-09-15]` FV cross-site routing fixed — one NAT rule scoped to Anaheim only
fv-ml1 could reach Anaheim and the internet but **nothing else** — not NH3, not
ESH, not Irvine. Mesh addresses (`100.64.0.x`) worked perfectly from it; LAN
addresses did not. That shape reads as a routing or Tailscale fault and is
neither.
## Root cause
One outbound-NAT rule on the FV OPNsense gateway, added 2026-09-13 and scoped to
a single destination. `docs/runbooks/fv-to-ana-nat.md` says so in as many words:
Interface: MESH (opt6 / tailscale0)
Source: 10.251.50.54/32 (fv-ml1 only)
Destination: 10.250.0.0/16 (Anaheim only)
"Other remote sites remain outside this fix's scope."
FV→Anaheim worked because a rule existed for it. FV→everywhere else failed
because none did. The runbook's own "Before" section describes the exact
symptom — far site receives with `src=10.251.50.54`, replies never complete.
## Fix
Three mirrors added (NH3 `10.100.0.0/16`, ESH `10.0.0.0/16`, Irvine
`10.6.110.0/24`), then all four broadened from fv-ml1's `/32` to the FV LAN
`10.251.50.0/24`, with descriptions rewritten to name the real scope. Applied
via `POST /api/firewall/source_nat/add_rule` + `set_rule` + `apply`, pre-change
`core/backup/download/this` taken each time. Commits `fa04f45`, `0ab9da5`.
⚠ Anaheim's original rule was written with `write_config` and is **invisible to
`source_nat/search_rule`** — the API cannot see or manage it. An API-managed
ANA `/24` rule was added alongside so all four destinations sit on the same code
path; the legacy `/32` is now redundant, harmless, and wants deleting from the
UI.
## ⭐ The diagnostic signature, so the next person skips the evening
Every one of these is true while the fault is live, and each one argues *against*
NAT being the cause:
- fv-ml1 reaches mesh addresses perfectly and LAN addresses not at all.
- The FV firewall log shows the outbound **passing** on tailscale0 with
`src=10.251.50.54` and nothing ever returning — nothing looks blocked.
- The far-side router genuinely receives and replies — proven with temporary
counting rules on nh3-scale: **5 packets in, 4 replies out**.
- Both peers' Tailscale `AllowedIPs` are correct, so cryptokey routing is fine.
- `ts-forward` on nh3-scale accepts everything from tailscale0; its DROP rule
shows **0 packets**.
**The discriminator that settles it: every OTHER site pair works.**
`nh3-docker → esh/ana/FV` and `esh-docker-vm → FV` all succeed, which rules out a
general subnet-to-subnet limitation and leaves outbound SNAT as the only
candidate. Check `/api/firewall/source_nat/search_rule` for a rule covering the
destination **before** investigating anything else.
## Wrong turns worth not repeating
- **Advertising `10.100.10.50/32` from nh3-dev** to make its LAN address
mesh-reachable — black-holed nh3-dev from ESH, Anaheim, FV and Irvine while
leaving its own LAN and the internet up. `ip rule` there puts `lookup 52` at
priority 5270 ahead of `main` at 32766, so becoming a subnet router let table
52 capture cross-site traffic a `RouteAll: false` node has no accepted route
for. Reverted; the working fix is a masquerade exception on nh3-scale
(`9dbd829`). See [[2026-09-15-nh3-dev-ts-input-masquerade]].
- **Remote-site MASQUERADE rules on nh3-scale** for the asymmetric-return
theory. They fired (counters incremented) but were not the fix; reverted
rather than left to accumulate.
- **`acceptSubnetRoutes` 0→1 on the FV gateway** — real and kept: the gateway
itself could not reach NH3/ESH before it. Necessary, not sufficient.

# `[2026-09-15]` Dead man's switch on fv-ml1 — mesh watchdog
Every path into Fountain Valley runs through equipment at FV. When fv-ml1 loses
its way back to the fleet there is no console, no local hands, and the BMC sits
behind the same gateway. This is the net under the next routing change.
`/usr/local/sbin/fv-mesh-watchdog.sh` + `fv-mesh-watchdog.{service,timer}`,
every 60 s. Canonical copies in `servers/fv-ml1/`. Commit `8c8559b`.
## Design choices that matter
- **Two anchors that cannot share a failure mode** — a plain-internet one
(`1.1.1.1`) and a mesh-only one (`100.64.0.1`). If only the mesh anchor fails,
the mesh is the problem and it acts. ⭐ **If BOTH fail it deliberately does
nothing** — the site uplink is down, Tailscale cannot fix that, and thrashing
tailscaled during an ISP outage turns a wait into an incident.
- **Threshold 5 consecutive failures**, counter reset on recovery.
- **Narrow remit**: only `tailscale set --accept-routes=false` + re-`up` with a
stored key + `systemctl restart tailscaled`. It touches no routes, no
firewall, no services — a watchdog with a wide remit is a second way to lose
the box.
- **Disable file** `/etc/fv-watchdog.disable` for planned work.
## Proven, not assumed
Positive control against a black-holed anchor (`MESH_ANCHOR=192.0.2.1` via the
conf file, real WAN anchor left in place so the uplink guard did not
short-circuit):
run1..run4 counted 1/5 .. 4/5, no action
run5 fired — tailscale up ran, tailscaled restarted, "restore attempt complete"
after counter reset to 0 once the real anchor returned
fv-ml1 stayed reachable throughout.
## Why it exists
Earlier the same session, `tailscale up --accept-routes` on fv-ml1 black-holed
it from its own LAN: it accepted `10.251.0.0/16` from the gateway — **its own
subnet** — and routed the local network through the tunnel. Recovery only worked
because its mesh address happened to still answer. Same family as the

# `[2026-09-15]` nh3-dev unreachable from the mesh at its LAN address — ts-input anti-spoof
`nh3-dev.nh3.internal` (10.100.10.50) failed from a mesh client while every
other NH3 host worked. Not DNS, not routing.
## Cause
A host that runs Tailscale installs an anti-spoof rule:
-A ts-input -s 100.64.0.0/10 ! -i tailscale0 -j DROP
The fleet's subnet routers run `NoSNAT: true` with RFC1918 exempted from
masquerade — **deliberate source preservation, and a departure from Tailscale's
own `--snat-subnet-routes=true` default**. So a mesh client's packet reached
nh3-dev's `ens18` still sourced `100.64.x` and died there, silently. Every NH3
host that does **not** run Tailscale was unaffected, which is what made it look
like a name-resolution fault.
Control that settled it: `nh3-pve` (10.100.250.60) is off-link, needs a gateway
hop, and works fine — it has no Tailscale and therefore no `ts-input` chain.
## Fix
One rule on nh3-scale (CT 107), above the RFC1918 RETURNs in
`/usr/local/sbin/mesh-exit-masq.sh`: `-d 10.100.10.50/32 -j MASQUERADE`. Commit
`9dbd829`, canonical copy `servers/nh3-pve/mesh-exit-masq.sh`.
## ⚠ Do NOT instead advertise the /32 from nh3-dev
Tried the same day and it black-holed nh3-dev from ESH, Anaheim, FV and Irvine
while leaving its own LAN and the internet up. `ip rule` there puts `lookup 52`
at priority 5270, ahead of `main` at 32766; becoming a subnet router let table
52 capture cross-site traffic a `RouteAll: false` node has no accepted route
for. ⚠ **A one-host check against its own LAN passes cleanly** — test all four

# `[2026-09-15]` I rebooted the FV edge firewall by probing API endpoints
Looking for the call that applies an OPNsense user change, I POSTed an empty
body at four **guessed** endpoints to see which returned 404. One of them was
`/api/core/system/reboot`. It returned 200 because it **ran**. The whole FV site
— including the BMC, which sits behind that gateway — went dark for **3.5
minutes**.
**The call I was looking for is documented in this repo**, in
`docs/pfi/opnsense-api-reference.md` § Service control: *"`reconfigure` writes
config and applies it, which is normally the one you want after a
`settings/set`."* I had opened that file twice and read around it.
## The rule
**Endpoints are ACTIONS.** A 404 tells you an endpoint is absent; a 200 tells
you it ran. There is no safe "does this exist?" POST against a live firewall.
Read the reference first; if you must discover, use **GET** on a
`get`/`search`/`status` command, never POST on an unknown name.
## Compounding failures worth naming separately
- **I kept polling FV afterwards** — its own runbook
(`fv-site-dark-20260913.md`) says in the header *"Do not leave watchers
running against FV addresses."*
- ⚠⚠ **I reported the site still dark while holding, unread, the file that said
it was up.** My own background watcher had logged
`WAN admin: 200 / gateway OK / fv-ml1 OK / ssh ALIVE` at ~204 s. The operator
was weighing a midnight drive against an outage that had already ended.
Actual outage 3.5 min; I reported ~15.
## The one useful thing that fell out
`POST /api/core/system/reboot` with `{}` is a **reliable remote reboot** for the
FV gateway — it came back cleanly on its own, which is a capability worth having
deliberately rather than by accident. `/api/core/service/restart/<id>` restarts
one service without the site outage and is almost always what you want instead.
## Also learned on the OPNsense API
- `auth/user` has **no** `reconfigure`; an API-only key edit persists in
`config.xml` and does nothing until the OS user sync runs at boot. Verified:
`authorizedkeys` + `shell` for `infra-ops` persisted immediately, SSH kept
refusing, and started working after the reboot.
- `POST` with **no body at all** returns `411 Length Required`. Send `{}`.
- Outbound-NAT rules written with `write_config` are **invisible** to
`source_nat/search_rule`. See [[2026-09-15-fv-cross-site-snat]].
