Deploy b820d34, measured: --no-enable-prefix-caching in the engine argv,
health 200, warm boot 76.57 s (compile cache intact), expert plan
unchanged (17.77 GiB / 7,762 slots), GPU KV cache 424,678 tokens (up
from 401,408 at the same byte ask - pool now prices ~7,456 B/token with
the per-block mamba checkpoint pages gone; still clears the 400,700
floor), zero gdn_hip lines, and the 40,771-token boundary probe
(13 x 3136 = 40,768 crossed) decoded the 1-400 count coherently
(0.997 monotone, tail ...398 399 400). e2e 32/33 - the failure is the
admin spec's FrankBook-Pro leg (mini asleep), environmental.
Two bash defects in the 9d8b185 prefix-cache wiring, both measured live
on the 2026-10-05 deploy attempt (unit crash-looped 190x, exit 127,
endpoint down for the whole 3600 s health window):
1. A # comment block inside the backslash-continued podman run
terminates the continuation: the comment swallows the joined line
and the flag line then runs as its own command
('--no-enable-prefix-caching: command not found'). The comment moves
above the run block, with a no-comments-in-chain note.
2. The ${VAR:+A}${VAR:--B} double-expansion is ambiguous: when the
variable is set, ${VAR:--B} parses as a SUBSTRING OFFSET, not the
:- default — measured render was '--no-enable-prefix-caching1'.
The flag is now branched explicitly into
FRANK_PRIMARY_PREFIX_CACHE_FLAG (exactly one of the two flags
reaches the engine; unset keeps the historical flag).
Seam: the render test sources the shipped env through the branch and
asserts the exact flag word the engine receives (render-assert, the
same pattern the spec knobs use). bash -n clean; all 22 frank-primary
seams pass.
Measured 2026-10-04 18:46:07 PDT (live podman logs): 48 gdn_hip state
faults in one 0.6 s burst — 'state out of ssm-cache range: max|S|=0 with
non-finite values (slot=42 head=3|8)', one per TP rank, 23 GDN layers
each — then the process-lifetime report cap. The guard's own text in
this build names it: 'known Qwen3.8-Flash-Next (QFN) flaw under prefix
caching … Mitigation: --no-enable-prefix-caching'.
Mechanism: prefix caching puts QFN on mamba_cache_mode 'align', which
checkpoints each sequence's GDN recurrent state into a mamba page per
3136-token block and re-seeds it from that page when a request resumes
from a cached prefix. The NaN state landed at the 13th boundary
(13 x 3136 = 40,768 — the reported ~40k mark) and persisted in the page:
every later turn of that conversation re-seeded the same non-finite
state for two heads, silently (fault-report cap already spent).
RAM ruled out the same day: zero MCE/EDAC records since the boot under
test, 8 GiB in-band pattern stable under live load, 4800 MT/s is the
JEDEC floor on 5600-rated DIMMs, and the two-head single-slot NaN
signature is a state-path fault, not scattered bit corruption.
Fix: FRANK_PRIMARY_NO_PREFIX_CACHING=1 -> --no-enable-prefix-caching
(flag renders in both directions from the knob). Cost: every turn
re-prefills the whole history instead of at most 3135 tail tokens.
Seam updated: the prefix-cache pin now asserts the conditional render
and the shipped OFF value. Runbook carries the evidence + acceptance
criteria; all 368 tests pass.
The host region was the ONE arena-plan term still autofitting per boot: with
no cap the planner binds it to MemAvailable AT BOOT minus PLE/process/api/
margin terms (boot 2026-10-05: 237.97 GiB -> 159.39 GiB usable; the same host
reads 75.4 GiB available while running). Demand is 105.48 GiB
(52.74/rank x 2 ranks, 23,040 swap-target experts); a boot where co-tenant
RAM squeezed the bound near that silently pins next-hottest experts VRAM-only
(pinned_extra warning, smaller swap region, no flag change). 120 GiB =
measured demand + 14% headroom on 246.1 GiB total. Semantics verified in the
shipped image: cap binds as the bound, exceedance only warns.
The GPU-side arena is unchanged (deterministic arithmetic over the same
constants): verify after boot that host reads '--expert-offload-mem' and
slots stay 7,762. Seam: red first (wiring + value), then green; full suite
368+1 green.
Verified in the shipped image (v1/worker/gpu/cudagraph_mem.py):
estimate_cudagraph_memory() checks VLLM_CUDAGRAPH_MEM_ESTIMATE_MB FIRST and
returns that MiB total outright, ignoring the BASE/PER_GRAPH pair — the only
way to state the CUDA-graph plan term directly instead of deriving it. We
keep shipping the pair (0/12) so a future spec-decode shape re-prices
automatically; documented the switch condition.
Also corrected two stale shape-G claims in the runbook that predated the
1.00 revert: the deployed shape block and the lever table both still said
util 1.0 / 'le=1 ceiling', while shape G ships 0.982.
- new active runbook frank-small-llama-mimo-q6k-2x200704.md: 21,276 used /
2,849 true free (inside the 2-3 GiB floor), decode 94.44 t/s vs 104.84 on
Q5_K_M - the rung costs a measured -10 % (weight-bandwidth-bound card),
512px red-PNG vision verified, and the new probe-size law (>=256 px: a
10x10 image undersupplies image tokens and the model answers 'video'),
nvidia-smi free-field law (driver holds ~450 MiB the subtraction hides)
- frank-small-llama-mimo-q5km.md retired; it keeps the boot-pair table and
becomes the Q5 rollback reference (3,571 free, 104.84 t/s measured)
- AGENTS.md fleet row, endpoint section, --parallel lesson, runbook index
(active row + two retired rows); LLM + root index entries
- Q6_K GGUF-vs-GGUF diff proven: template and all 46 KV keys byte-identical
to Q5_K_M - the vision probe scare was probe size, not payload
The freed third slot funded exact V; the remaining ~3.5 GiB of honest
nvidia-smi free (3,571, not the 4,046 total-minus-used I quoted - the
driver holds ~450 MiB of reserve) funds the +875 MiB of Q6_K weights.
Projected landing ~2.7 GiB free, inside the 2-3 GiB floor; measure on
boot, step the pool one 12,288-token increment if it lands under 2 GiB.
- payload dir MiMo-Q6K/ made self-contained (mmproj hardlinked from
MiMo-Q5KM/, link-count-2 verified)
- env/serve/deployer/bats repointed; download script now fetches and
verifies Q6_K (7,793,710,624 B, ef96d05a...) with Q5_K_M documented as
the rollback; payload sha verified live on the host before deploy
- seam green 14/14 against the stub engine
- new active runbook frank-large-rocmfpx-q6agent-uncensored-mtp.md: the
Q6_0_ROCMFPX_AGENT file (ftype 114, 339 type-102 + 159 type-103 tensors),
27.6-28.1 t/s at 86.8% draft acceptance, the measured ngram-mod chain
rejection (-15% prose: recurrent-state rollback disabled), the
bench-window hardening laws
- frank-large-rocmfpx-q8agent-mtp.md retired; rollback section corrected
(gufo payloads removed from disk 2026-10-03 - that rollback is now a
re-download; the aligned Q8 file is the direct one, still on disk)
- frank-small-llama-mimo-q5km.md reshaped to 2 x 200704 with fully
unquantized f16 KV: boot-pair table gains the measured row (20,530 used /
4,046 free), 104.84 tok/s, slot-window contract at 200704, rollback to
the 3x180224 + q8_0-V shape documented
- AGENTS.md: fleet table rows, both endpoint sections, the chain law
extended with the recurrent-model measurement, the --parallel law with
the reslice, runbook index (active + retired)
- LLM/index.md + root index entries updated
Record the live numbers and the UTIL 1.0 verdict (unbootable: worker init
demands free > budget; ValueError on both ranks before a single weight loads).
Driver used 30.97 of 31.86 GiB; the 0.89 GiB/card margin held through a live
4,096-token generation at ~38-39 tok/s.
Worker init refuses budget >= device total on BOTH ranks:
ValueError: Free memory on device cuda:0 (31.29/31.86 GiB ...)
NRestarts=2 crash loop, zero weights loaded. Experts stay at the v1 shape
(graph term 0.07 GiB, KV 3.1665e9 = the 400,700-token ask); only the budget
returns under the law. Arena 17.78 GiB / ~7,912 slots predicted.
Two plan terms were still unspent: the CUDA-graph charge (shape F's own boot
reported a NEGATIVE capture delta, -0.06 GiB, so the 256 MiB base pool was
fiction -> charge 0 + 12 MiB/graph = 0.07 GiB) and the budget (util 0.982 -> 1.0,
the field's le=1 maximum). Together +0.82 GiB of expert cache: plan target
18.35 GiB / ~8,016 slots. KV_BYTES 3.15e9 -> 3.1665e9 = the 400,700-token ask at
the engine's measured 7,891.8 B/token. Cost of the force, recorded: driver
high-water ~30.4 GiB of 31.86, so ~1.5 GiB of real margin per card; rollback is
UTIL=0.982.
The arena is budget - non-expert - KV reserve - graphs - overhead. With util
capped at 0.982 (never 1.00) the graph estimate is the only plan term this repo
can shrink: the fork charges an analytic 256 MiB + 52 MiB/graph = 0.55 GiB where
the engine's own post-capture line reports 0.31 GiB, so pricing it at
256 + 12/graph returns ~0.24 GiB to the expert arena. MNBT 1024 -> 2048 is
arena-free: the registry overhead is base + 0.22 GiB per 1024 ABOVE its nbt 4096
anchor, and the fitted 5.25 GiB was fitted AT 4096.
Frank's order, two messages: "extend the max context of frank-small to
200700 per individual stream without further quantization", then
"reduce it to 2 streams for a total of 401400-ish tokens, set ubatch to
1k", then "unquantize the KV if we have extra space".
CTX_SIZE 540672 -> 401408 with PARALLEL 3 -> 2 gives n_ctx_slot 200,704:
above the 200,700 the harness compacts at, so a full-length request
lands in one stream instead of a 400 exceed_context_size_error. The pool
must divide evenly across slots and stay 256-aligned for the FA path,
which is why it is 401,408 and not 401,400.
CACHE_TYPE_V q8_0 -> f16: the freed third slot is exactly what pays for
unquantized values (24.5 -> 32 KiB/token), and the budget lands back in
the 2-3 GiB band Frank set on 2026-10-02 instead of leaving ~6 GiB of
the card idle. The asymmetric-KV contract that created this endpoint is
spent with it; both --cache-type flags stay explicit.
--batch-size/--ubatch-size are now passed (2048/1024). The endpoint had
never passed either, so it ran on engine defaults nobody wrote down.
Franksdank-Runbook: serverAppConfigs-docs/LLM/frank-small-llama-mimo-q5km.md
Frank's order: replace frank-large with
kingjones777/Qwen3.8-27B-Uncensored-ROCmFP4-STRIX-MTP-GGUF's
Qwen3.8-27B-Uncensored-Q6_0_ROCMFPX_AGENT.gguf, following that card.
The file is ftype 114 — 339 GGML_TYPE_Q6_0_ROCMFPX (102) + 159
GGML_TYPE_Q8_0_ROCMFPX (103) + 353 F32 over 851 tensors,
qwen35/64 layers/full_attention_interval 4/4 KV heads/262,144 window —
read out of its own header. The pinned ROCmFPX build already knows both
types (ggml.h 102/103 plus convert/cpy/getrows/mmq/fattn device paths
for 102), so no rebuild: the fork stays at 36e9acd and the payload
directory is the only new host state.
Card compliance, all already our flags: Q4_0 draft head (not Q8_0),
--spec-draft-n-max 4 (the knee on both cards), --spec-draft-ngl 99,
--jinja, --fit off, -fa on, -dio, one slot at full window, thinking with
the card's own sampling triple (which the file also embeds as its
general.sampling defaults). Kept from the deployed shape: the BF16
projector (this repo ships only a Q8_0 one; BF16 is the file verified
4/4 on spatial ground truth here) and the byte-identical MTP head, which
the new script hardlinks instead of re-fetching 1.6 GiB.
Franksdank-Runbook: serverAppConfigs-docs/LLM/frank-large-rocmfpx-q6agent-uncensored-mtp.md
Four harness gaps that block an honest MTP re-measurement:
- measure: AR_TEMPS sweeps sampling temperatures (default "0,0.7"). Draft
ACCEPTANCE is sampling-dependent — a greedy draft matches a greedy target
exactly and is rejected more under a non-greedy target — so judging a spec
arm only at temperature 0 judges half the contract. The unsuffixed keys stay
temperature 0, so every historical number remains comparable.
- window: capture an evidence.log sidecar (expert-plan lines, compile path,
graph sizes, /metrics spec-decode and cache counters, OOM signatures). The
arena/overhead/reserve numbers exist ONLY in the boot log; an arm that loses
decode speed is otherwise unexplainable afterwards.
- orchestrator: FRANK_PRIMARY_AR_ENV_FILE stages an env other than the repo's,
which is how arms A/B without mutating the checkout (the fingerprint covers
whatever is staged, so the memo can never answer one arm with another's
numbers), plus METRIC lines for the swept temperatures and the evidence dump.
- scripts/autoresearch/frank-primary-arms.sh: runs a sequence of full windows
(baseline, MTP3+probabilistic with a step-4 capture ladder at precise memory
ON, the same at the default overhead, and the vendor SEQS-16 shape), gating
each staged env on its JSON knobs still parsing AFTER sourcing — an unquoted
{"temperature":0.7} loses its quotes at source time and reaches the engine as
{temperature:0.7}, which is a 20-minute boot wasted.
Three engine knobs that were impossible to set without editing the run line:
FRANK_PRIMARY_SPEC (--speculative-config), FRANK_PRIMARY_COMPCONFIG
(--compilation-config) and FRANK_PRIMARY_GEN_CONFIG
(--override-generation-config). Each holds the whole JSON value; empty or
unset means the flag is absent, so the shipped shape E argv is unchanged.
The seam re-pins the law that justified the omission: "speculative decode is
ABSENT BY MEASUREMENT" compared the wrong pair — c1248d4 retired MTP by
weighing fp8+MTP4 (37.4-40.6 t/s, 54% acceptance) against the bf16 no-spec
boot (36.4-39.4), bf16 then proved unbootable, and fp8 came back WITHOUT MTP.
fp8+spec was never measured against fp8+no-spec on one shape, the no-spec
incumbent runs ~30 t/s under the fleet's 35 t/s target, and every vendor
flash-next recipe ships MTP3.
Also in the seam: a dead assertion is deleted (a failing `! grep` mid-test is
exempt from bats' errexit, so the pre-precise-memory `! grep
--expert-precise-memory` never ran), and the knob test asserts by RENDERING the
flag from the sourced env instead of grepping for an assignment.
Live after the 1ac4d48 deploy: 'expert_precise_memory': True, runtime overhead
5.25 GiB, expert cache space 17.22 GiB / 7522 slots, swap region 13.7 GiB /
5986 slots, GPU KV cache 398,658 tokens / 1.99x, pool 3,150,000,000, MNBT 1024
-- the probe's projection is now production.
Compile cache proven on consecutive boots of that shape: cold 'Compiling a
graph for compile range (1, 1024) takes 179.24 s' / 'torch.compile took
188.26 s'; warm 'Directly load the compiled graph(s) ... from the cache, took
2.143 s' / 'torch.compile took 3.97 s in total' / 'init engine ... took 41.13 s
(compilation: 3.98 s)'. Host dir 1.4 GB / 4,707 files. Time to /health stays
payload-bound (490 s warm), so the claim is ~184 s of inductor/AOT build per
restart, not a proportional boot cut.
Tests: 367/367.
Measured by boot probe on the shape-D base (production stopped, candidate
booted AS the service), plan numbers read off the engine's own log:
runtime overhead 7.60 -> 5.25 GiB (precise gfx1201 TP2 registry)
expert cache 14.87 -> 17.22 GiB
slots 6,496 -> 7,522 (+1,026, +16%)
swap region 13.7 GiB / 5,986 slots
boot healthy in 420 s, no OOM
'--expert-precise-memory': True also appears in non-default args, so a silent
argparse drop is visible. The pool is NOT cut (option A) because the pool is
not an arena lever: 3.15e9/rank keeps shape D's measured 1.99x concurrency,
and a 2.2e9 arm probed in the same window (277,686 tokens, 1.38x) is recorded
as the conservative fallback.
Boot-cost bug found while diffing Frank's 3xR9700 recipe: the image ships no
/root/.cache at all, our boot writes 1.1 GB of vLLM AOT/torch_compile
artifacts (4,665 files) plus 229 MB of comgr JIT kernels into the ephemeral
layer, and podman rm -f discards them — so every deploy/restart/reboot re-pays
'torch.compile took 181.20 s in total' (173.19 s of it one graph). Mounting
FRANK_PRIMARY_CACHE_DIR at /root/.cache persists both and hides nothing.
GPU_MAX_HW_QUEUES=2 added at Frank's direction (real HSA knob); not A/B
measured. Retracted my own recipe-diff claim that cudagraph_capture_sizes
needed pinning: capture is 3 PIECEWISE + 2 FULL graphs, 3 s, 0.31 GiB.
Tests: 367/367.
`deploy.sh <target>` with no `--service` also walks the per-service revision
markers and restarts everything behind HEAD whose paths changed — a drain, not
a sync. That is how the latent plex gate bug surfaced: the backlog fired all
at once and plex's http:// readiness probe, which can never succeed against a
PMS that drops plain HTTP off-loopback, burned its full 600 s and aborted the
run with every later service left pending.
Both facts recorded: AGENTS.md gains the drain law under Deployment, log.md
gains the plex entry with the evidence chain.
deploy_plex gated on `curl http://127.0.0.1:32400/identity`, which can never
succeed: Plex accepts the TCP connection (it arrives on the container's eth0)
and then answers with nothing, so curl reports "Empty reply from server" (52).
Measured 2026-10-02 on a plex that was healthy the whole time —
`https://127.0.0.1:32400/identity` returned 200 in 44 ms while the gate burned
its full 600 s and failed the deploy.
The repo already knew this law in another place: tests/caddyfile.bats pins the
plex vhosts to a TLS upstream with the comment "PMS drops plain HTTP
off-loopback". The deployer's gate never got the same treatment, and plex's
per-service revision had been behind long enough that the gate had not run
against this posture until now.
-k because PMS serves its own self-signed cert on 32400.
index.md intro and mermaid nodes still described 4 x 262144 fp8/bf16 and
frank-small at 2 x 262144; the active-deployment list had no frank-primary
entry at all. Fixed both, plus a malformed GLM list item.
log.md gains the shape-D entry (the SEQS=2 constraint, the arena-lever
measurement, the 2x2 probe table, the measured 1.99x), and the frank-small
entry's stale consequence bullet now points at the resolution.
frank-small runbook: the compaction-fit note is corrected - the 200704 window
moved frank-primary's trigger to 140,492, which fits a 180,224 slot again.
Comments/docs only - no functional change. The live boot of c769ff2 reported:
GPU KV cache size: 398,658 tokens,
Maximum concurrency for 200,704 tokens per request: 1.99x
expert cache space 14.87 GiB / 6,496 slots of 2.344 MiB
The arena prediction (6,496) landed exactly; the concurrency prediction (2.04x)
did not, because the per-token KV price is SHAPE-DEPENDENT: 7,701 B/token at
MAXLEN 262144 (6.1e9 -> 792,069 tokens) but 7,892 at 200704 (3.146e9 ->
398,658). Never extrapolate a concurrency figure across geometries.
Also smoke-verified: three concurrent 67-token requests answered in parallel,
~4.1 s each - the 3 slots are real, and the pool admits 2 full-length.
Re-applies the desired shape incrementally on the proven-good fp8 3x262144
base, after bisecting why the first attempt (30904ba) crash-looped.
Root cause: `--max-num-seqs 2` cannot compile on this model. AOT
build_guards(strict_error=True) inside profile_run -> _dummy_run specializes
`query_start_loc`'s width to SEQS + 1 (3 at SEQS 2, 4 at SEQS 3) and the
ConstraintViolationError kills engine init ~7 min in. MNBT is orthogonal:
SEQS 2 failed at MNBT 1024 AND 2048; SEQS 3 passed at both. KV dtype was a
red herring. Measured by four single-variable boot probes.
Arena lever measured: the expert arena is sized from `max_model_len` via the
registry-priced KV reserve (9190 B/token x max_model_len), NOT from
--kv-cache-memory-bytes. 262144 -> 14.30 GiB / 6,248 slots; 200704 ->
14.87 GiB / 6,496 slots. The 6.1e9 -> 3.15e9 pool cut bought zero arena and
is a runtime-headroom lever.
Shape: MAXLEN 200704, SEQS 3 (unchanged - the only slot count that compiles),
KV_BYTES 3.15e9/rank = 2.04x full-length concurrency at 7,701 B/token fp8,
MNBT 1024, gather 32x64, no spec decode, no prefetch, no precise-memory.
The 2 x 200704 fp8 / MNBT 1024 shape (30904ba) crash-loops at boot: the
engine dies in determine_available_memory -> profile_run -> _dummy_run with
the SAME torch.compile dynamo constraint that killed the bf16 2 x 262144
shape on 2026-10-01:
RuntimeError: Worker failed with error 'Constraints violated
(L['query_start_loc'].size()[0])! You marked it as dynamic but your code
specialized it to be a constant (3)'
Not an OOM. Restoring the last shape measured serving (fp8 3 x 262144 /
KV 6.1e9 / MNBT 2048 / arena 6,248) so the endpoint serves again; the
desired edits are re-applied one at a time from this base.
The 2026-10-01 bf16 shape (2 x 262144, --expert-precise-memory)
crash-looped at graph capture — the arena is DEVICE-resident and that
shape had 0.13 GiB to spare. The plain bf16 2 x 262144 also did not stay
up: 0 bytes free at runtime, and a real client request (995-token prompt,
max_tokens=261149) killed the worker with .
The correction is a pool cut, not a downgrade. FP8 KV (7,701 B/token),
two 200704 windows (401,408 tokens -> 3.091e9 B floor, pinned 3.15e9),
MNBT 1024. The fork's expert planner sizes the arena AFTER the KV
override, so the ~2.95 GiB/rank reclaimed becomes arena: ~7,500 slots
vs 6,248. Two contexts at 200704 is a capacity contract, not a
throughput one (2-way concurrency summed BELOW parity at 4064 ctx), so
the slot buys the VRAM headroom long generations need.

Goal: Make frank-primary faster: raise decode tok/s on the tcclaviger vLLM endpoint (dankserver :7770, Qwen3.8-Flash-Next-Uncensored-FP8, 2x R9700, automatic tiered-expert offload). Context size may be altered (MAXLEN/SEQS/KV_BYTES and friends); quantization may NOT be altered (the 131-shard FP8 payload and the digest-pinned image are frozen).
Runbook, both indexes, AGENTS.md (topology row, endpoint section, three new
Key Lessons, one stale SGLang label in the bench list) and the bundle log now
describe the deployed shape: pool 540,672, 180,224 tokens per conversation,
f16 K + q8_0 V, mmproj vision, 21,684 used / 2,441 free of 24,576 MiB, 106.8
tok/s decode, 3,814 t/s prefill.
The claims that mattered:
- three contexts buy 180,224 tokens per conversation, not the native 262,144,
and a longer prompt is a hard 400 - so models.yml contextWindow is 180224
and frank-primary's 183,501-token compaction request no longer fits here
(forward pointer added to the retired SGLang runbook, which asserted it)
- the vision tower bills ~1.4 GiB for a 918 MB file, established by subtracting
two measured boots, not by a formula
- /v1/chat/completions ignores the legacy top-level 'images' field: the model
invents a color; only the image_url content part reaches it
Measured after the first 3-slot deploy: 3 x 196,608 booted (n_slots=3,
n_ctx_slot=196608, multimodal loaded) but used 22,972/24,576 MiB - 1,153 MiB
free, outside the 2-3 GiB band. The two measurements now recorded in
frank-small.env price the vision tower at ~1.4 GiB (non-KV 7,390 -> 8,859
MiB), so the pool drops 49,152 tokens (16,384/slot, 1,176 MiB) to land ~2.7
GiB free. The bats budget gate is recalibrated to the measured 9 GiB non-KV
cost, which now rejects the 3 x 196,608 shape instead of blessing it.
CTX_SIZE 589824 / PARALLEL 3 -> three independent 196,608-token conversations
(a mamba hybrid cannot share one KV cache, so per-slot window = pool/slots;
3 x 262,144 would need 18.4 GiB of KV alone and busts the card).
Vision comes back via bartowski's mmproj-MiMo-V2.6-Distill-Qwen-9B-f16.gguf
(918,166,048 B, sha256 ff348f31..., fetched + verified by
scripts/download-frank-small.sh): the Q5_K_M GGUF ships no v.* tensors, so
--mmproj IS the image path. MMPROJ_FILE without a colon default so an explicit
empty value is a real text-only opt-out, and the deployer now gates on the
projector exactly as the serve script does.
Budget is measured, not guessed: the 2 x 262,144 shape used 20,190/24,576 MiB,
which prices non-KV cost at 7,390 MiB. Three slots + projector land near
22.5 GiB, i.e. ~2 GiB spare - the bottom of the requested band, to be
confirmed by measurement and laddered if it lands outside 2-3 GiB.
Staged 59 GiB of retired LLM payloads on Dankclaw to
~dank/.AGENTTRASH/20261002-retired-llm-payloads/ (vLLM MiMo BF16, Qwen3.5-9B
MTP source, both DFlash dirs, Gemma4-12B-QAT, SGLang MiMo INT8) and corrected
every doc claim about what is on disk: gufo's rollback pair (Q4_K_XL weights +
the Q8_K_XL DFlash2 drafter) and frank-small's Q6_K stay in place, so the
rollback paths in the tags' env files still resolve. The vLLM-era frank-large
fetch trio moves to old/ with its runtime; runbook links updated.
frank-large: new runbook frank-large-rocmfpx-q8agent-mtp.md — the ftype-115
tensor-type lock-in that forced the fork, the pinned build (set_rows history),
the measured MTP A/B (17.0 vs 7.6 t/s decode, acceptance 0.462), the live
client contract (reasoning_content, effort fold, vision restored) and rollback.
frank-small: new runbook frank-small-llama-mimo-q5km.md; q6k marked retired
(rollback target). gufo runbook marked retired (rollback target). Both indexes,
the fleet topology table, the vision/models.yml notes, the benchmarking law and
three new Key Lessons updated.
The repo's highest-quality rung is ftype 115: 311 tensors of
GGML_TYPE_Q8_0_ROCMFPX, a type only the ROCmFPX fork reads, so the runtime
moves from gufo to scripts/build-rocmfpx.sh's pinned fork build (36e9acd) —
the first build on this host measured to load this file without the
2026-08-25 set_rows segfault. One session at the native 262,144 window, f16
KV (64 KiB/token, 16 GiB), the repo's Q4_0 MTP head drafting 4 tokens, plus
the bundled BF16 projector so the endpoint has vision again.
The serve script now honors caller environment overrides over the env file
(a plain source let the file win, which made single-run overrides no-ops) and
defaults apply only when a value is unset, so an explicit LLAMA_BIN='' is the
error it reads as.
One quant step down from Q6_K on the same CUDA build and the same shape:
2 x 262,144 with K f16 + V q8_0. The 0.86 GiB freed from the weights is
headroom, not a new window — the native 262,144 cap is already reached,
and f16 V would still cost 3.96 GiB more than the pool can carry.
Live battery green after deploy #3: alias, reasoning split into
`reasoning`, tool_calls, /metrics acceptance pos0 69% pos1 44% - the
cross-model MTP head performs as measured in the bench window.
The first crash-looping boot (51 restarts): serve received the host path
/home/dank/models/... but the models tree is mounted at /models inside the
container, so transformers failed 'Repo id must be in the form
namespace/repo_name' before the engine even built. Same conversion the spec
draft already used. Pinned by bats. Root docs index links the new runbook
(seam required it) and the work log records the crash-loop plus the 52 G
payload reclaim.
The 2026-10-01 first deploy refused /home/dank/models/Qwen3.5-9B because
the handler checked for a single model.safetensors (the dflash layout);
the Qwen3.5-9B MTP head ships 4 shards behind model.safetensors.index.json.
Same dual-layout acceptance as the serve script, now mirrored and gated by
the seam. The gate fired before the stop, so the live gufo unit was never
touched (health 200 throughout).
New runbook carries the roof math, the measured three-arm spec table, the
greedy-text numerics trap, the reasoning-field contract change and the
rollback tag. LLM index and AGENTS.md fleet table, bench policy and runbook
index follow; the frank-small index entries catch up to the SGLang cutover
(entry was missed on 2026-10-01). Work log records the cutover.
Engine: digest-pinned docker.io/kyuz0/vllm-therock-gfx1151 (vLLM 0.30,
TheRock ROCm 10, Triton GDN kernels); the serve script gates the image by
REPO DIGEST, the payload (config + index + exact shard count), the spec
draft (BOTH weight layouts: single model.safetensors for dflash, sharded
index for the Qwen3.5-9B MTP head), and whole /dev/dri, sweeps the bench
identity vllm-mimo, then exec podman wait so a container death trips
Restart=always. Shape: 4 x 262144 at util 0.45 (KV grows only on the 8
full-attention layers), MTP 2 draft tokens.
Measured 2026-10-01 window (frank-large stopped): base 13.1 t/s decode
(~94% of the LPDDR5x BF16 roof), DFlash-8 17.4, MTP-2 19.8 with 71%/44%
per-position acceptance - the cross-model head works because vLLM reads the
draft from a separate path while MiMo ships zero mtp.* tensors. Spec arms
do not preserve greedy bf16 text (batched-verify reduction order).
The seam was rewritten around the new laws (18 tests): unit self-healing,
digest gating, engine wiring, the measured spec table, the retired gufo
gates, the deployer MainPID check. frank_small port test follows the
PORT -> FRANK_LARGE_PUBLISH rename. Rollback: tag frank-large-gufo-q4kxl-20261001.
