The gate failed twice in the same spec for two different reasons and then passed
33/33 on a manual re-run. Future sessions should re-run before treating the
DEPLOY INCOMPLETE banner as a real fleet fault.
ExecStop runs 'podman stop -t 120' but the unit never set TimeoutStopSec, so
systemd's 90 s default cut the graceful stop short: journal shows 'Stopping
timed out. Terminating.' then 'Failed with result timeout' on 2026-10-01
13:27:17 — every stop of this unit was logging a failed stop. 180 s covers the
engine's drain with margin, and the seam now guards the RELATIONSHIP
(TimeoutStopSec > the podman grace) rather than a literal.
StartLimitIntervalSec is a [Unit] directive; the copy in [Service] made systemd
log 'Unknown key StartLimitIntervalSec in section Service' on every load. Seam
asserts it appears exactly once and not in [Service].
Frank's call 2026-10-01: MAXLEN 262144 x SEQS 3 = 786,432 tokens of contract.
Measured fp8 KV costs 7,698 B/token (4-slot boot 8,311,013,376 B -> 1,079,582
tokens; 5-slot boot 10,388,766,720 B -> 1,350,182 tokens), so the pool floor
for the contract is 6.054e9 B. Pinned at 6,100,000,000 (~792k tokens, ~5.9k
margin) so the remaining ~2.2 GiB versus the 4-slot shape goes to the expert
ARENA - the fork sizes its decode-critical expert cache from the remainder
after weights, pool and workspace.
MNBT 2048 (Frank): the arena sweep measured 6,499 slots at every rung <= 4096,
so the larger batch costs the arena nothing.
Seam retargeted (3 seqs / 6.1e9 / MNBT 2048); docs + AGENTS row + log updated,
including the closed DCP investigation.
--decode-context-parallel-size 2 fails VllmConfig validation at boot:
'Decode context parallelism for GQA/MQA requires --tensor-parallel-size (2) to
be greater than the model's total number of KV heads (2)'. DCP shards KV along
the sequence dimension AFTER KV heads spread across TP ranks, so it needs
TP > num_kv_heads; this model has 2 KV heads, so TP >= 4 — four GPUs, not two.
Recorded with the rest of the survey (PP/DP/EP/multi-node verdicts for this
box), the container-injection requirement for /home/dank/mtp_measure.py
(it imports /bench_iter.py by absolute path and must be copied in), and the
re-measured deployed capacity (1,079,582 tokens / 4.12x).
DCP is passed only when FRANK_PRIMARY_DCP is set, so the deployed shape is
unchanged. Verified in this fork: DCP reuses the TP ranks when PCP is
disabled (tp % dcp == 0), so TP=2 + DCP=2 fits the two R9700s with no extra
ranks; the flash_attn backend carries DCP support, the 36 linear-attention
layers of this hybrid do not — which is what the A/B window tests.
Replaces llama.cpp Gemma4-12B-QAT (payload + binary retained as rollback).
SGLang in a self-contained python3.12 venv with an extracted CUDA 13.0
nvcc toolchain for the sgl-kernel/flashinfer JIT.
Shape: fp8 KV, pinned 606,208-token pool / 4 x 151,552 slots, bf16 mamba
states pinned at 32 slots (the engine autofills the ssm pool to a fixed
~5.1 GB regardless of dtype), eager prefill (no headroom for graph
capture), no spec decode (the checkpoint ships no mtp.* tensors despite
mtp_num_hidden_layers=1 — NEXTN drafts with an uninitialised 4.24 GiB
ghost at 0% acceptance).
Verified: 83.9 tok/s decode, 170k single prompt, 4 concurrent 54k
requests, vision (in-checkpoint tower), reasoning_content field.
Five 262144-token contexts passed every boot gate (KV 1,350,182 / 5.15x) but
left 0 bytes free at runtime: a real client request (995-token prompt,
max_tokens=261149, sampling params straight from models.yml) killed Worker_TP1
with torch.OutOfMemoryError 'Tried to allocate 50.00 MiB ... 0 bytes free'.
Boot is not proof of runtime survivability.
Four slots x 262144 fp8 (KV_BYTES 8,311,013,376/rank) returns ~1.93 GiB per
rank for activations/graph capture.
Unit: Restart=always instead of on-failure — a runtime worker fault makes
vLLM's API server exit clean, so ExecStart returned 0 and on-failure never
fired, leaving the endpoint down until a human noticed. Also
StartLimitIntervalSec=0 and OOMScoreAdjust=-500.
Frank's call after the night ladder: five contexts at the model's full native
262,144 window beat six shortened ones. Six full-length contexts do NOT fit at
any KV dtype (6 x 241664 fp8 asked 10.70 GiB against 9.18 GiB free — the
6-seq graph/activation footprint leaves too little for the pool); 5 x 262144
at fp8 PASSED on the first rung: KV_BYTES 10,388,766,720/rank, measured
'GPU KV cache size: 1,350,182 tokens, Maximum concurrency for 262,144 tokens
per request: 5.15x' (39,462 tokens of margin).
Also documented: the SEQS=3 bf16 max (241,664, KV 732,359 / 3.03x) measured
earlier the same night, and the root-cause read that the 7.2 GiB KV ceiling
law was the MTP4 workspace, not VRAM. Seam and harness (contextWindow 262144)
re-pinned.
Night ladder result (Frank's subtract-16k method): 262144 and 245760 both OOM
at CUDA graph capture ('Tried to allocate 76.00 MiB ... 0 bytes free'), 237568
passed (KV 718,606 tokens), and the +4096 bonus step PASSED -> 241664 is max
possible and DEPLOYED at util 0.98 (KV 732,359 tokens / 3.03x concurrency at
241,664-token requests). Util stays 0.98: lowering it shrinks the engine's own
budget instead of buying slack.
Client contract restored (the GLM rollback d91379d dropped all three and the
qwen rollback inherited the gap): --reasoning-parser qwen3 fixes the malformed
thinking block (thinking was landing inline in content with a dangling
</think> and a null reasoning field), --enable-auto-tool-choice with
--tool-call-parser qwen3_xml makes tools work, and
--default-chat-template-kwargs enables enable_thinking + preserve_thinking.
Harness: contextWindow 241664 (compaction gap recomputed), preserve_thinking
moved into chat_template_kwargs.
The 0.98 boot died at KV allocation: torch OOM tried 10.28 GiB (the exact
3x262144 bf16 pool = 11,047,010,304 bytes) with 9.46 GiB free per rank.
The rootless bench probe had booted the same numbers; the root unit's
pinned-expert path holds ~0.8 GiB/rank more. Util 0.90 returns ~2.5 GiB/rank
of workspace with the pool ask unchanged; measured KV capacity law
(798,280 tokens at 11.05e9) unchanged.
Overnight redo campaign verdict + Frank's call: the fp8+MTP4 shape is retired
to git tag frank-primary-fp8-mtp-20261001. The new incumbent: KV cache
unquantized (auto), no speculative decode, KV_BYTES 11,047,010,304/rank
(engine-measured 798,280 tokens, 3.05x concurrency at 262,144-token
requests), MNBT 1024, MoE gather 32x64 (+18.7% decode, grows with depth).
Measured at the deployed shape: 39.38/38.79/36.42 tok/s (166/1087/4064 ctx).
Seam re-pinned: the 7.2 GiB/rank KV ceiling was the MTP4 workspace, not VRAM;
spec decode absent by measurement; bf16 trade documented (clean cache +
262k windows for ~14% decode at 4064 ctx).
- AGENTS.md: fleet table + frank-primary section back to qwen FP8 + MTP4
(37.4-40.6 tok/s, 54% acceptance); GLM runbook moved to the retired index.
- runbook: RETIRED verdict — DFlash2 drafter served and drafted but
acceptance pinned 1.00-1.38 on every text class including verbatim
repetition (mis-wired aux capture, not a weak drafter); 5x slower than
baseline at ~1.2 acceptance.
- log.md: 2026-10-01 rollback entry.
- deploy-remote.sh: LLM_PRIMARY_CONTAINER back to frank-primary-qwen;
glm-probe joins the legacy sweep list.
- frank_primary_unit.bats: re-pinned to the qwen shape — KV qualification
law (7.2 GiB/rank, 3.65x concurrency; 9/16 GiB OOM), fp8 q8/q8 KV
PRESENT, MTP4 PRESENT (3.1-3.4x over the 12.11 no-spec baseline), no tool
dialect, automatic offload. The old 'MTP buys zero' law carried the
prefetch tax and is retired.
DFlash2 experiment declared failed 2026-10-01: the drafter serves and
drafts (12.8 tok/s proposed) but acceptance is pinned at 1.0-1.38 on ALL
text classes including verbatim repetition — the aux-hidden-state capture
semantics are wrong (single-stream entering-state vs post-layer/comb is
the untested alternative). At ~1.2 acceptance the 8-token verify tax makes
decode 5x SLOWER than the 9.9-10.0 baseline (1.6-1.8 tok/s measured).
Restores the verified 37-40 tok/s shape: qwen3.8-flash-next FP8, MTP4,
prefetch off, 200k x 3 seqs, fp8 KV.
use_aux_hidden_state_outputs lives on the gpu_model_runner instance
(gpu_model_runner.py:623/678), not on the spec config, so the first
registry check never fired and the reserve stayed at 13,600 B/token.
Switch to method in {dflash, dspark, extract_hidden_states}.
The dflash boot cleared the unifier and the kpool tail (02/03) and died on
KV capacity: on the generic path the mamba states are NOT aliased into the
MLA pages (the glm5 tensor layout's whole point), so the capacity estimator
demanded ~30.6 GiB fixed against 0.92 GiB available (the plan's KV reserve
registry only knows the target's 13,600 B/token).
Patch 04 keeps the aliased glm5 pool and appends the drafter's uniform
group and per-layer hidden-state groups beside it: grouping partitions
hidden + draft specs, the layout returns a 10-tuple, the builder sizes one
shared backing allocation (pool + extras), and the memory estimator adds
the extras. Patch 04b extends the GLM registry kv_bytes_per_token by the
drafter (4,096 B/token) and hidden-state (5 x hidden x 2 B/token) costs so
the expert plan reserves enough.
Local smoke tests (CPU torch + real spec classes) validate grouping shape,
layout recognition, builder block math and memory accounting against
synthetic GLM+draft+hidden spec sets. Apply-verified: reproduces shas
5521e50b... / 1a623d5c...
Patch 02 (MLA-multiple max page) cleared the KV page-size unifier: the
dflash boot now reaches cudagraph capture. New blocker: the kpool decode
kernel asserts tail_kv_cache.shape[2] == pool_size; KpoolTailSpec pins
block_size == index_kpool, so the unifier's divisible branch must never
grow it. Patch 03 = 02 + a KpoolTailSpec branch that pads page_size_padded
instead. Apply-verified: reproduces patched sha 5093e4b7... Runbook
updated with the full KV grouping journey.
Runbook: the five-version evolution recorded, each trap named (method
hand-write, Protocol-base MRO kill, wrong-wrapper attrs). The decisive
discovery: the runner checks the LOADED instance, which for GLM-5.3-Flash
is the multimodal Glm5NextForConditionalGeneration holding the text model
as self.language_model — v4's attrs on Glm5NextForCausalLM were invisible
to it. v5 (attrs + methods on both wrappers) passes: both TP workers log
'Using Eagle3 auxiliary layers from config: (6, 15, 25, 34, ...)' and the
DFlash2 drafter resolves + loads. Log: the DFlash bullet updated from
'the trunk simply does not implement' to 'gap closed; serving end state
still unproven (window RAM contention interrupted the boot twice)'.
The v4 boot named the actual miss: model_runner.py:425 calls
set_eagle3_aux_hidden_state_layers(self.model) on the instance model_runner
LOADED -- and for GLM-5.3-Flash that is Glm5NextForConditionalGeneration (the
multimodal wrapper; APIServer log: 'Resolved architecture:
Glm5NextForConditionalGeneration'), which wraps the text model as
self.language_model = Glm5NextForCausalLM (glm5next/common/model.py:1113).
v4 put the three presence-checked attributes only on Glm5NextForCausalLM,
so the isinstance check on the conditional still failed with the same
RuntimeError.
v5 adds to BOTH wrappers, MRO-safely (attribute route, no Protocol base):
- Glm5NextForConditionalGeneration: supports_eagle3 / has_own_lm_head /
has_own_embed_tokens + the two methods delegating to self.language_model
(the pixtral.py:498 pattern);
- Glm5NextForCausalLM: the same three attributes + the two methods that
unwrap to self.model (the EagleModelMixin trunk -- v1's correct bodies).
Also proven by MRO simulation: the ForCausalLM's five-base ordering cannot
take SupportsEagle3 as a base in ANY position, so inheritance was never a
viable route for this model.
base 008eeaa2... -> patched bc9913a1..., apply-verified against the pinned
image (patch -p1 reproduces the sha256 and matches the mounted file).
The v4 window boot named the real presence-check rule: isinstance against a
runtime_checkable Protocol walks __protocol_attrs__ (which includes members
inherited from BASE protocols) and getattr_static()s each one off the instance,
breaking on the first missing attribute. SupportsEagleBase declares
has_own_lm_head/has_own_embed_tokens as plain instance-var annotations, so
v3's bare supports_eagle3 flag still failed. Replicated in-image with stock
typing: flag-only class -> False; flag + the two base members -> True.
v4 declares all three on Glm5NextForCausalLM:
supports_eagle3: ClassVar[Literal[True]] = True
has_own_lm_head: bool = False
has_own_embed_tokens: bool = False
(False is correct for the two: the wrapper delegates embed/lm_head to its
trunk. The MRO-safe attribute path is kept from v3.)
base 008eeaa2... -> patched 60f27aad..., apply-verified against the pinned
image (patch -p1 reproduces the sha256 and matches the mounted file).
v2 (inheriting SupportsEagle3 as a base) taught the real lesson: the isinstance
check PASSES and the class then dies at creation with
'Cannot create a consistent method resolution order (MRO) for bases ...'
-- GLM's outer wrapper already inherits vLLM Protocols (SupportsPP,
MixtureOfExperts, HasInnerState, IsHybrid) whose ordering is incompatible with
appending another Protocol base.
v3 avoids the MRO entirely: declare
supports_eagle3: ClassVar[Literal[True]] = True
as a class attribute on Glm5NextForCausalLM. Runtime-checkable Protocols do
presence-based isinstance, so the bare flag satisfies supports_eagle3(model)
without touching the MRO. The aux-layer plumbing stays on the trunk via
EagleModelMixin.
base 008eeaa2... -> patched 4c9a632b..., apply-verified against the pinned
image (patch -p1 reproduces the sha256 and matches the mounted dflash-patch
file byte for byte).
v1 hand-wrote set_aux_hidden_state_layers/get_eagle3_default_aux_hidden_state_layers
and the boot reproduced the identical 'Model does not support EAGLE3 interface'.
Reason: supports_eagle3() is an isinstance check against a runtime-checkable
Protocol whose members include a required ClassVar flag
(interfaces.py:1663 supports_eagle3: ClassVar[Literal[True]] = True), so methods
alone do not satisfy it. Inheriting SupportsEagle3 -- the idiom every model in
this image uses, including the fork's own DFlashLagunaForCausalLM -- supplies the
flag, SupportsEagleBase's has_own_lm_head/has_own_embed_tokens, and working
default implementations of both methods; the hand-written methods are deleted.
base 008eeaa2... -> patched 5eea89c5..., apply-verified against the pinned image.
Runbook: corrected method name, recorded the Protocol trap as the generalizable
lesson for future spec-decode ports.
The frank-primary section still carried the retracted framing ('a latent bug the compile
exposes' in the mHC/KDA path) and listed only three compile patches. It now records:
six apply-verified artifacts across two WIP changelists (compile 01-05 + the DFlash2
enabling patch), the measured facts (lru_cache does not protect a probe; suppress_errors
does not cover breaks; the trunk can never satisfy fullgraph because its indexer
metadata syncs to host), the single remaining blocker
(KeyError: 'in_proj_qkvbfg_a', raised in a callee dynamo inlines into
Glm5NextDecoderLayer.forward, not at any of the four nn_modules lookups and not a literal
string lookup -> currently a dynamo-side name-resolution failure, not a demonstrated fork
bug), and the two operational gotchas this session paid for (the launcher silently
dropping VLLM_COMPILE_FULLGRAPH=0, and the PYTHONPATH sitecustomize fork bomb). The
DFlash2 paragraph now says the aux-hidden-state contract is written, and that the
engine's refusal was literally 'Model does not support EAGLE3 interface'.
tests/run.sh: 362 seams pass.
Clarifies scope in the artifact header: torch.compiler.disable is itself a graph break,
so 05 helps only a hypothetical fullgraph=True route (where the workspace acquisition
would be better restructured out of the forward than made opaque). It is kept because
the discovery is real and the wrapper is a no-op when nothing is compiling, but it is
not required for the break-tolerant route whose only confirmed blocker is the dynamo
name-map KeyError.
Also verified in this pass: glm53-dflash-01-aux-hidden-states.patch applies cleanly to
the pinned image and reproduces its recorded patched sha256 (4ff6ff8d...), so all six
artifacts in scripts/patches are now apply-verified.
Recording the incident: a diagnostic sitecustomize.py mounted at /probe on PYTHONPATH
produced a self-replicating chain of python3 processes 19+ levels deep inside the probe
container (sitecustomize runs in EVERY interpreter; the hook imported torch/vLLM at
startup; something in that import chain spawned a helper python which inherited
PYTHONPATH and the hook, and spawned again). Found alive 18 minutes later, 33 probe-tagged
processes. Killed with 'podman rm -f glm-probe' (the container cgroup owns every
generation) and verified by counting /proc/<pid>/environ for the marker variable --
never by pattern-killing an interpreter name, since this host runs python in production
containers (romm, jellyfin, plex, glances). Fixed at the source with an env marker that
children inherit, verified with a two-generation test: gen 1 installs, gen 2 stays inert.
The runbook now carries the hazard, the guard, the kill recipe, the conjunction the
restore must verify, and the no-overlapping-jobs rule. Patch 06
(glm53-dflash-01-aux-hidden-states.patch) is documented in the DFlash2 section, and the
/probe diagnostic is marked retired -- TORCH_LOGS answers dynamo questions with no
startup hook.
tests/run.sh: 362 seams pass.
glm53-dflash-01-aux-hidden-states.patch: implements the interface whose absence makes
the engine refuse the drafter with 'Model does not support EAGLE3 interface'. Adds
EagleModelMixin to Glm5NextModel, captures the single-stream hidden state entering each
requested layer in the loop, returns (hidden_states, aux_hidden_states) as a tuple when
the list is non-empty, and exposes set_aux_hidden_state_layers /
get_eagle3_default_aux_hidden_state_layers on Glm5NextForCausalLM -- the contract read
out of interfaces.py:1694/1712, eagle3_utils.py:26-31, deepseek_v2.py:1551-1585 and
cudagraph_utils.py:621, with kimi_k25/pixtral as the delegation reference.
Independent of the compile changelist (01-05); it patches the same file as 01, so 01
goes first if both are applied. Scope is honest in the header: this makes the interface
present (the prerequisite for driving DFlash2), it does not promise draft quality and is
not a decode-speed fix.
Five runs of the changelist now reproduce the same single failure with breaks genuinely
tolerated (patch 01+02+03+04, VLLM_COMPILE_FULLGRAPH=0, VLLM_USE_AOT_COMPILE=0,
R4D_GLM_FUSE_QKV_RMSNORM=0): the trunk TRACES ('Dynamo bytecode transform time: 1.08 s')
and the boot dies on KeyError: 'in_proj_qkvbfg_a'.
What it is NOT, each ruled out by measurement rather than argument:
- not one of dynamo's four nn_modules lookups: /home/dank/dynamo-probe wraps three of
them and stayed silent over two runs, with the probe's install line confirmed in both
the API-server and worker processes;
- not a dynamo-internal failure: TORCHDYNAMO_VERBOSE=1 adds no internal stack trace;
- not a literal string lookup: the name appears tree-wide only as the KDA layer's
attribute (kda.py:217, used at :407) and in the load_weights shard table
(model.py:780-785); the four sites in the
quantization utils do compute exactly this bare key but every one is guarded
(), so none can raise it;
- not the pluggable-layer registry, which is keyed by class name.
What it IS: a plain Python KeyError raised inside the traced
Glm5NextDecoderLayer.forward, in a callee dynamo INLINED (frame chain
profile_run -> _dummy_run -> execute_model -> glm4_1v.py:2358 -> the compile wrapper ->
eval_frame.compile_wrapper -> Glm5NextModel.forward:748 -> module._call_impl ->
Glm5NextDecoderLayer.forward:456; the reported line is that method's def line, which is
how inlined frames surface).
Patch 03's header and the runbook now record the remaining instrument (TORCH_LOGS=+dynamo
and grep, or wrap the inlining candidates — the mHC CustomOps and the indexer op — with a
KeyError probe), and the two breaks that are real but non-fatal in this configuration
(patch 04's fused-norm launcher cell, patch 05's workspace acquisition).
tests/run.sh: 362 seams pass.
This engine ignores SIGTERM: after systemctl stop its container sits in podman ps
state 'Stopping' for 20+ minutes WHILE STILL ANSWERING /health with 200. So a liveness
probe is a lying oracle for a window restore — twice a restore reported PROD HEALTHY
while systemctl is-active said failed and the runtime mask was still in place, because
the old container was still serving.
Records the conjunction the restore must verify (is-active == active AND is-enabled ==
enabled AND no /run/systemd/system/<unit> mask symlink AND the container is owned by
the unit and not Stopping) and the four-step repair recipe (mv the runtime mask away —
it survives stop and blocks start; daemon-reload; reset-failed — a failed unit refuses
to start; podman rm -f — podman stop hangs on the same SIGTERM).
Also records the overlap hazard: a later job's 'podman rm -f glm-probe' cleanup
deleted an in-flight job's container, so one compile round produced no evidence at all
('no container with name glm-probe found'). Check proc:// for running jobs before
opening a window.
tests/run.sh: 362 seams pass.
Root-caused the moving failures: they were my own scratch launcher. Its compile
branches were restructured and the '-e VLLM_COMPILE_FULLGRAPH=0' line was dropped, so
four consecutive boots mounted the wrapper patch while _FULLGRAPH still defaulted to
True — and with fullgraph=True EVERY break is an error, so each boot reported whichever
break came first (cell -> workspace -> compiler-disable). I had blamed
TORCH_LOGS=graph_breaks for the difference; that was wrong, the flag only logs. The
launcher sets the env var again, and patch 04's header, the runbook and the work log
now carry the true run history as a table instead of the bad theory.
New artifact: scripts/patches/glm53-compile-05-workspace-acquisition-opaque.patch —
the indexer acquires its shared workspace INSIDE the forward (its profile-run branch
literally says 'Reserve workspace for indexer during profiling run'), and
v1/worker/workspace.py:_ensure_workspace_size reads ContextVar/ubatch state, which
dynamo cannot trace. Wrap both call sites in a torch.compiler.disable'd helper
(narrower than decorating the workspace manager, which every model would go through;
a no-op when not compiling).
All five artifacts verified against the pinned image: applied in sequence with patch
-p1 they reproduce their recorded patched sha256 exactly (6e9cb81b…, 0751852e…,
732363bb…, 84969993…, c154115a…).
tests/run.sh: 362 seams pass.
Working the dyno name-map blocker one step at a time, with the tools to see it:
- All four patch artifacts are now genuine diff -u patches (they were prose + pseudo
hunks before, useless to patch(1)). Verified against the pinned image: each applies
clean and reproduces its recorded patched sha256 (6e9cb81b… / 0751852e… / 732363bb…
/ 84969993…).
- New: scripts/patches/glm53-compile-04-fused-qkv-rmsnorm-optout.patch — takes GLM's
MLA block off the fused-norm JIT kernel (R4D_GLM_FUSE_QKV_RMSNORM=0; the flag is
already a constructor arg glm5next sets at attention.py:583). Reason: in
models/common/ops/fused_qk_rmsnorm.py the kernel object is bound at line 223, AFTER
its use at line 211 — the launcher family (@kernel_launcher, 39 call sites) is what
breaks dynamo's break analysis.
- New diagnostics, both reusable and recorded: TORCH_LOGS=graph_breaks +
VLLM_USE_AOT_COMPILE=0 to name each break with its user stack, and
/home/dank/dynamo-probe (sitecustomize.py on PYTHONPATH, VLLM_DYNAMO_DUMP_ATTRS=1)
to print the dynamo name-map miss detail. Gotchas: a .pth on PYTHONPATH is NOT
executed, and the scratch launcher reset ENVARGS (now ${ENVARGS:-}), which silently
dropped env vars and wasted a boot.
Measurement discipline correction: I first recorded the 'Read uninitialized cell' and
'Unsupported method call' failures as fatal blockers. They are not established as
such — they appear only when TORCH_LOGS=graph_breaks is set, while a flag-free
break-tolerance run gets past break handling and dies on the name-map KeyError. The
likely mechanism is that graph_breaks logging makes dynamo build a break
*explanation*, and that analysis itself trips on the uninitialized cell. Patch 04's
header, the runbook and the work log now carry the confound explicitly rather than
the overclaim.
tests/run.sh: 362 seams pass.
DFlash2: fetched incoai/GLM-5.3-Flash-DFlash2 (2,342,169,800 B, sha256 matches the
Hub LFS oid) and tried --speculative-config {"method":"dflash","model":"/draft"}.
Config and drafter are accepted; the worker dies with 'Model does not support
EAGLE3 interface' - so the only gap is the target-side aux-hidden-state contract
(set_aux_hidden_state_layers + per-layer capture + the two-value forward return,
as deepseek_v2.py demonstrates twice in this image). Recorded the exact interface,
the GLM-specific unknown (what the single-stream state entering layer k means for
an mHC multi-stream trunk) and the honest expectation: no speedup on a
token-proportional pointwise bound.
fp8 KV: recorded the deciding measurement - the fork's KV reserve model is
dtype-blind (the fp8 boot printed the identical 1760 MiB / 13600 B-per-token plan),
so fp8 cannot buy capacity even if the gfx12 MLA path were rewritten. Verdict: do
not spend effort there.
Compile blocker narrowed from 'a latent GLM bug' to dynamo's name map: the
KeyError is thrown by torch/_dynamo/output_graph.py's nn_modules lookup (:3000,
registered :1259/:1384, _modules[..] prefixes stripped :1225), i.e. the compiler
cannot resolve a submodule by name while tracing the decoder layer. Next step is
TORCHDYNAMO_VERBOSE=1, with the note that the scratch launcher resets ENVARGS.
tests/run.sh: 362 seams pass.
A torch-profiler kernel-time window (496 decode tokens, rank0 trace parsed for
device-activity time) on the deployed GLM-5.3-Flash shape falsifies this page's
own "the expert gather is the bound" explanation:
46.18 s of kernel time / 496 tokens = ~93 ms per token (actual step ~104 ms)
34.8 % vectorized_elementwise_kernel 708,500 launches (1,428/token)
10.0 % r4d_gemm_moe_w4a16_nt_b16_m64 (the MoE GEMM)
6.7 % elementwise_kernel_manual_unroll
6.4 % wvSplitK_hf_sml_ (split-K GEMM)
8.9 % router: sbtopk + warpMergeSortTopK + bitonicSortKVInPlace
6.5 % r4d_mhc_* (hyper-connections)
1.05 % r4d_moe_lru_gather_kernel <-- the retracted suspect
The earlier arithmetic was circular (it assumed the gather consumed the whole
step). The real bound is unfused pointwise glue: the fork compiles its own Qwen
trunk (support_torch_compile in models/qwen4_exp/amd/model.py) and not its GLM
trunk, so the engine boots with "provides neither a compiled submodule nor
breakable CUDA graphs. Overriding to FULL_DECODE_ONLY." That also explains why
MTP4 measured flat — pointwise cost scales with the token count, so spec decode
amortizes nothing here — and it retires arena/hit-rate tuning (the gather is 1 %).
Staged as documented patch artifacts (not wired into any serve script; the
engine does not yet boot with them) — scripts/patches/glm53-compile-0{1,2,3}*.patch:
-01 models/glm5next/common/model.py decorate Glm5NextModel (R4D_GLM_COMPILE)
-02 model_executor/kernels/r4d_lib.py freeze 10 capability probes that do
os.path.exists/.so lookups inside the traced forward. functools.lru_cache
does NOT protect them: dynamo re-traces the wrapped body even when warm
(verified in-image); a plain module-global read compiles.
-03 compilation/wrapper.py make fullgraph=True opt-out, because
suppress_errors does NOT cover graph breaks and this trunk can never
satisfy fullgraph (indexer metadata syncs to host — .item() at
glm5next/amd/sparse_indexer.py:263,419).
With all three the trunk traces (Dynamo bytecode transform time 1.08 s) and dies
on KeyError: in_proj_qkvbfg_a in the mHC/KDA path — a latent bug the compile
exposes, and the remaining blocker.
Also records two structural constraints: no new HIP kernels are possible (r4d.so
ships without sources), which binary-blocks the fused router at GLM's 288
experts; and DFlash2 for GLM is a TARGET-side port, not a drafter port
(incoai/GLM-5.3-Flash-DFlash2 is architectures ["DFlash2DraftModel"] +
model_type qwen3, already mapped at registry.py:636; glm5next lacks only the
aux-hidden-state plumbing deepseek_v2.py demonstrates).
Runbook frontmatter, intro, mermaid and wall section, AGENTS.md and the work log
corrected to match the measurement. tests/run.sh: 362 seams pass.
Two operational facts the cutover surfaced: PYTORCH_CUDA_ALLOC_CONF=
expandable_segments:True is part of the qualified shape (the plan fills VRAM to
its modelled headroom, so the default allocator's fragmentation fails
profile/graph capture — measured on the deployed unit), and the deploy's e2e
gate drives the admin open-links spec, which walks every guarded vhost
including 192.168.0.112:8989 on FrankBook-Pro — a sleeping Mac mini fails that
spec and reports DEPLOY INCOMPLETE while the engine is healthy.
The deployed unit failed its first boot with the engine core OOMing during
profile/graph capture: "Tried to allocate 662.00 MiB. GPU 0 has a total
capacity of 31.86 GiB of which 240.00 MiB is free ... try setting
PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True". The expert-offload plan
fills VRAM to its modelled headroom by design, so the default allocator's
fragmentation leaves the capture phase nothing — every successful bring-up
probe (both scratch-port and 7770) carried this env, and the repo recipe
dropped it.
Also pins the seam: the setting is part of the qualified shape, not an
optional tuning.
Payload: Intel/GLM-5.3-Flash-W4A16-AutoRound (AutoRound symmetric int4 group
128, auto_round:auto_gptq, 34 shards + 2 extras, 113,074 tensors, ~170 GiB).
It is the only W4A16 checkpoint this fork can serve with expert offload: its
quant_method "auto-round" is overridden to "inc", which routes the MoE to
libr4d's grouped W4A16 GEMM (R4dW4a16MoEMethod). A compressed-tensors W4A16
build of the same model resolves to TritonWNA16Experts, which has no offload
recipe, and refuses to serve at all (170 GiB of experts cannot fit 64 GiB of
VRAM, so offload is mandatory).
Shape: tcclaviger RDNA4 vLLM fork (same digest-pinned image as the 2026-09-29
qwen cutover), TP=2, 131,072 ctx x 2 seqs, bf16 KV (fp8 is ILLEGAL here — it
disables the sparse MLA backend's rope-free Triton path, the only MLA decode
gfx12 has), util 0.98, NBATCH 2048, --enable-expert-offload
--expert-precise-memory, prefix caching, glm47 tool + reasoning parsers,
MTP and expert prefetch absent by measurement.
Measured: decode 9.9-10.0 tok/s, prefill 918 tok/s (warm), arena 14.51 GiB =
2,383 slots/rank over 12,096 host-backed experts (73.64 GiB pinned/rank).
THE 35 tok/s TARGET IS NOT MET and the shortfall is measured: live telemetry
(R4D_LRU_TELEMETRY=1) gives a 0.53-0.66 per-layer hit rate, a step moves
0.82 GiB of misses in ~100 ms = 8.2 GB/s effective against a link measured at
22.74 GB/s — the same structural gather-path gap the qwen campaign found.
Growing the arena 13.08 -> 14.51 GiB changed decode by nothing.
Rejected by measurement: MTP4 (head loads, acceptance 3.76-4.90, but decode
unchanged and prefill collapses 918 -> 255 — a verification forward gathers the
union of the batch's experts), NBATCH 8192 (identical prefill).
Also: scripts/patches/gpu_worker-kv-cap.patch (fork-local fix for a KV-reserve
model that under-counts GLM's per-sequence KDA state; not needed by this shape),
runbook, AGENTS.md row + section, both indexes, work log.
Rollback: 2339fae (qwen FP8 + MTP4).
The classic 'podman images | grep -q' pattern races under set -o pipefail:
grep exits on its first match, podman dies SIGPIPE (141) writing the
remaining RepoDigests lines, and pipefail promotes 141 to the pipeline
status — the gate reads 'no match' and refuses to deploy (2026-09-30,
dankserver). Same bug in the serve script (it would restart-loop the
same way). Fix: capture podman's output into a variable first, grep the
variable. Patched in the R9V September deploys by luck of timing.
Unquoted value + set -a sourcing parses 'qwen-fp8' as a command ->
ExecStart exit 127 -> unit restart loop (caught on the first deploy).
The deployer's wait_for_health was killed and will re-run on the fresh
deploy.
Replace the R9V radiance fork with the tcclaviger RDNA4 vLLM stack (the
digest-pinned image the 2026-09-29 tuning campaign measured), serving
orcarouter/Qwen3.8-Flash-Next-Uncensored-FP8 (131 shards, 172.8 GiB,
already on disk) with MTP4 spec decode.
Qualified by boot probe on 2026-09-29:
- MAXLEN=200000 x SEQS=3 (600k total) at --kv-cache-dtype fp8 (q8/q8 KV):
'GPU KV cache size: 729,545 tokens; Maximum concurrency for 200,000
tokens per request: 3.65x' at KV_BYTES 7.2 GiB PER RANK.
- KV_BYTES is per-rank: global 16G and 9G both OOM (worker tried to
allocate the full size; ~7.5 GiB/rank is the ceiling with the arena).
- prefetch OFF by law (telemetry: 36% precision, ~50% wasted traffic);
TunableOp off (corrupts numerics).
- decode at this shape: 42.94/34.55/36.09 tok/s; arena 6,032 slots.
Trio: frank-primary.env (all FRANK_PRIMARY_* keys), serve-frank-primary.sh
(direct podman run; entrypoint execs vllm serve; waits on the container),
frank-primary.service (root unit, same ExecStop law, new container name
frank-primary-qwen). Deployer gates rewritten (image digest + shard count
+ weight-map index). download-frank-primary.sh is now inventory/verify
(repo is GATED — 401 anonymous, masked LFS hashes; payload already on
disk). Seam rewritten for the new contract. Pre-cutover tag:
frank-primary-r9v-q8-20260929.
PORTMAP=7773:7770 hook; health 200 on 127.0.0.1 and 192.168.0.235,
decode through the published path in band. 7773 chosen over 7770
(frank-primary owns 7770 when it returns). Log bullet recovered from a
misplaced insert into the 2026-09-28 cleanup section.
Repo tag qwen-fp8-tuned-20260929 at f532e03; serve script launches the
tcclaviger image by digest sha256:da402966... (local alias
qwen-fp8-runtime:tuned-20260929) — the floating :latest is no longer
referenced.
Source reading in the qwen-fp8 container: glm5next is registered with an
amd/ backend dir + DSA indexer; r4d.so has native moe_dsfp4/moe_dsfp4_mt1
entries (has_dsfp4()==True), so the old 'MXFP4 = emulation, missing
kernels' verdict is dead for this fork. DSFP4 = MXFP4 weights + DeepSeek
activation law. Offload recipes exist for mxfp4 and W4A16 (R4dW4a16MoEExperts
in offloader/expert.py:114). GLM gate is now the payload format
(compressed-tensors MXFP4/W4A16, none public) + a HIP boot probe.
The KV trim is inert: arena identical (5,648 slots) at 4.5 and 4.03 GiB
(planner buckets; the trim went to margin). Final 256k config
MAXLEN=262144 KV_BYTES=4328521728 prefetch off; full-speed alternative
MAXLEN=184224 at 3 GiB.
Asked for iterative decode/prefill improvement at a 32k working point
without touching the model or the quantization. There isn't one: gufo's
served settings are already at this engine's tuned point, so no config
change was made and none is proposed.
Measured on the repo's own prose and shell sources at 32,762 prompt
tokens, salted per run against a warm prefix cache, 3-5 repetitions:
* --prefill-chunk 512 -> 8192 moves prefill 410.7-412.4 t/s. A 16x change
in chunk size, 0.4% out. The lever is dead at this depth.
* --draft-tokens 5 -> 10 gives 13.79-15.86 t/s decode, all inside the
run-to-run noise. The 5-rep confirmation REVERSED the 3-rep leaders:
dt9+chunk4096 looked best and came last (12.86), the deployed config
came first (14.71).
* --draft-policy fixed vs adaptive: no effect. --min-draft-tokens:
rejected by the engine ("DFlash2 requires ... 1"). MTP: unsupported for
Q8 targets (token_embd.weight is Q8_0).
* --context 262144 -> 40960, tested as a diagnostic: no gain, and it
would break models.yml's declared contextWindow. Not shipped.
What does move the number is speculation itself — 6.65 t/s off vs ~15 t/s
on, 5.3x — and it is already enabled.
The two traps that cost most of the wall time are now in AGENTS.md's
benchmarking policy, because both produced FALSE results:
1. gufo bench cannot rank speculative settings and inverted the ranking.
Its corpus reports acceptance=0.933 +/- 0.000 with an identical trace
sha256 across draft widths — the same highly-predictable text every
run. It reported 29-37 t/s where real traffic gives ~15, and made
dt16 look 6% faster than dt7 when real text made it 14% slower.
2. A live A/B needs >=128 generated tokens. At 8, inter_token is
first-token noise; the first pass produced a nonsense ordering that
the 128-token pass reversed.
Plus the Server-Timing header is `ttft;dur=402.485` — the unit rides in
the NAME half, so splitting on "=" keys the dict "ttft;dur" and every
lookup silently returns nothing. Four configs reported "no Server-Timing"
while the header was present on all of them.
The disk was at 93% with 137G free. Nine retired payloads are now moved
to ~/.AGENTTRASH/20260928-retired-models/ with a MANIFEST.md giving a
restore command per item — moved, not deleted, and nothing is freed until
the purge is approved. Every one maps to a runtime already retired in the
runbook index.
Only the .gguf was taken from Qwen3.8-27B-UD-Q8_K_XL/: the live
frank-large DFlash2 drafter lives in that directory and stays put. The
manifest warns against restoring the directory wholesale.
Kept: checkpoints/ (23G) — unreferenced by the repo, but ComfyUI is live
and its workflows were not searched, so it is not confirmed dead. Also
logs/, because x4e-run.log is a SPARSE file (3.3G apparent, 4K real) and
frees nothing.
The reference check caught a live bug: serve-frank-small.sh's fallback
MODEL_DIR still pointed at the retired GSQ-RCO payload frank-small served
on 2026-09-16/17. frank-small.env has always overridden it, so the drift
was invisible — but a missing or unreadable env file would have turned a
config problem into a "missing asset" naming a model that is no longer
there. Repointed at Gemma4-12B-QAT/, which the env file already sets.
Not taken, by request: podman images (279G reclaimable, 95%) and the
uv+pip caches (73G). Together 352G of regenerable garbage, larger than
what was reclaimed here.
The 29.3G payload rollback target went with the rest, so the payload-only
rollback is now a re-fetch first; the runbook and AGENTS.md say so.
The target moves from unsloth/Qwen3.8-27B-GGUF:UD-Q8_K_XL to
ajgazin/Swift-1.5-Qwen3.8-27B-Uncensored-Dynamic-MTP-GGUF's UD-Q8_K_XL —
an abliterated fine-tune of the same base, under the non-OSI SWIFT OPEN
LICENCE 1.0. Port, alias, context, drafter and client contract are
unchanged.
Compatibility was settled from the GGUF headers before fetching anything:
both files parse to the same architecture (qwen35), the same 866 tensors
with identical names in identical order, zero per-tensor ggml_type or dim
mismatches, and the same MTP head. Two metadata differences that look
alarming are no-ops, confirmed against gufo's source — general.file_type is
deliberately not consulted (the file gufo already served records Q4_K_M
while containing no Q4_K tensor), and Swift's extra
qwen35.attention.recurrent_layers key is never read; layer kinds come from
full_attention_interval, which both files carry as 4 and which agrees.
The load test agreed: 9.2 s to listening, 66.5 GiB of the 116.7 GiB iGPU,
no loader warnings, and a green contract battery including a two-turn tool
loop.
The DFlash2 drafter did not move, so the payload is now two files in two
directories: DRAFTER_DIR is its own tunable. That broke the deployer's
stray-run sweep, which keyed on the target filename and would have stopped
matching — a stray run would then have held 7770 past the port gate. It
now keys on the drafter, which every frank-large command line carries.
The fetch script sends no auth header: the repo is public, and a token on
the curl command line is world-readable via /proc/<pid>/cmdline. The
anonymous transfer ran at 1.8 MiB/s; the host token through a mode-600
curl -K config reached 7 MiB/s.
Test seam: the mutation pass found four real gaps. Two fetch assertions
were satisfied by a header comment rather than the URL assignment, so
repointing a repository left them green, and nothing bound the env's
MODEL_FILE/DRAFTER_FILE to the filenames the fetch scripts download. Both
are now explicit. A harness bug worth recording: a bats --filter that
matches no test reports zero "not ok", indistinguishable from a mutation
that survived — the harness now checks the 1..N count. 16/16 caught.
The ad-hoc status commands kept producing wrong readings, most seriously
reporting "MemAvailable 0.0 GiB" on a host that actually had 240 GiB free.
Cause: /proc/meminfo separates key from value with a TAB, so
grep MemAvailable /proc/meminfo | tr -s " " | cut -d" " -f2
returns an empty field and awk prints 0.0. A false "host is out of memory"
reading is worse than no reading, because it invites an unnecessary abort.
dankstatus.sh parses on a colon split (tab-agnostic), cross-checks
MemAvailable against MemTotal before printing either, and refuses to print
a zero value. It also pins the rocm-smi CSV column order (device, total,
used) which was previously read swapped, and takes only the first line of
systemctl is-active/is-enabled, which emit more than one line here.
Incidental finding while validating: rocm-smi reports card2 (the 7700X iGPU)
as 0.50 GiB total, not the 123.0 GiB torch.cuda reports. torch was exposing
the GTT aperture. The device is smaller than documented, not larger.
Tests: 346/346 pass (no test surface touched).
Public, ungated repo so no auth header is sent — a token on the curl
command line is world-readable via /proc/<pid>/cmdline. Size and sha256
are the Hub LFS values (31457990272 / 9076f99a…), verified after fetch.
Not wired into frank-large.env: the gufo load test has to pass first.
Live numbers from the 2026-09-28 deploy: 13 s load to listening, RSS
30.6 GiB, ttft 549.8 ms / inter-token 24.2 ms on a short prompt, and a
green contract battery (health, ready, /v1/models at 262,144, content +
reasoning_content, tool_calls, SSE, and a two-turn tool loop).
Also recorded: gufo accepts every request field the harness sends in
extraBody and the full reasoning_effort set, both verified 200 — which
is why models.yml's reasoningEffortMap fold is now optional rather than
required, and why it is being kept anyway.
