+ceiling (400 naming the limit, never truncation); `models.yml`
+`contextWindow: 200700` must match or the harness discovers the wall as a 400.
+`HALOGEN_MAX_TOKENS_CAP=65536` + `HALOGEN_QUEUE_TIMEOUT=7200` are a coupled
+pair; the harness `maxTokens: 57344` stays under the cap (over-cap is a 400
+naming the limit — README, never a 413). Thinking tokens COUNT against the

+`content` and the reasoning in `reasoning_content`.
+`HALOGEN_DRAFTER=2` = DFlash2. **No server-side sampler**: an absent
+temperature is greedy, so the thinking recipe exists only in `models.yml`
+`extraBody`. `response_format` is unsupported (no constrained decoding).

+BOTH MNBT 1024 and 2048 with `torch.fx.experimental.symbolic_shapes.Constraint

+specialized it to be a constant (3)`; SEQS 3 passes at both. `model_runner.py`
+sizes that input buffer `max_num_reqs + 1` and `_dummy_run` sets
+`num_reqs = min(max_num_batched_tokens, max_num_reqs)`, so the width is
+`SEQS + 1` for any `MNBT ≥ SEQS` — MNBT only moves the compile RANGE
+((1,1024) vs (1,2048)). `--enforce-eager` bypasses the path but drops CUDA
+graphs. The same failure class killed the 2026-10-01 bf16 2×262144 shape.
 
-The engine auto-sets the attention block size (mamba-page floor); the
-expert plan's registry prices KV per token; the expert arena (6,574 slots
-x 2.344 MiB = 15.05 GiB/rank) is the decode-critical region — cutting it
-for KV headroom collapses the offload hit rate.
+**The expert arena has THREE reachable levers: `max_model_len`, the overhead
+term, and the CUDA-graph estimate.**
+The fork's planner sizes expert cache as `budget − non-expert − KV reserve −
+graphs − overhead`, and the KV reserve is registry-priced at 9190 B/token ×
+`max_model_len`: 262144 → 2.48 GiB reserve → arena 14.30 GiB / **6,248 slots**;
+200704 → 1.91 GiB → 14.87 GiB / **6,496 slots**. Δreserve 0.57 GiB = Δarena
+0.57 GiB. The 6.1e9 → 3.15e9 pool cut bought **zero** arena; it buys runtime
+headroom (the shape it replaced died with `0 bytes free` on a real 995-token
+request). The second lever is `--expert-precise-memory`, **ON since
+2026-10-02**: it swaps the registry's default overhead (7.60 GiB = fitted +
+compile/graph-capture headroom) for the fitted figure, and the 2.35 GiB
+difference lands in the arena — measured plan lines at 200704 × 3: overhead
+5.25 GiB, expert cache **17.22 GiB / 7,522 slots** (+1,026 / +16 %), swap region
+13.7 GiB / 5,986 slots, boot healthy in 420 s. The pool stayed at 3.15e9
+deliberately: because the pool is not an arena lever, cutting it would cost
+concurrency (a 2.2e9 probe reports 277,686 tokens / **1.38×**) and buy no slots.
+The arena (2.344 MiB per slot) is the decode-critical region — cutting it for KV
+headroom collapses the offload hit rate.
+
+**Free VRAM on this endpoint is NOT arena headroom (2026-10-03 audit).**
+`rocm-smi` reads ~3.5 GiB free per card after hours of real traffic, but the
+planner charges `budget = total × util` against terms that overstate reality:
+the KV reserve is registry-priced at 9190 B/token (`1.91 GiB` at 200704) while
+the real pool bills 2.93 GiB at 7,892 B/token, and the precise overhead (5.25
+GiB) is far above the idle-measured figure. So the visible free space is the
+estimator gap, not allocatable arena. `gpu_memory_utilization` is a real arena
+lever (each +0.01 = +0.32 GiB) but **0.982 is the law, and 1.00 is UNBOOTABLE
+on this fork — measured 2026-10-03**: the worker init demands
+`free > budget`, and at `le=1` budget == device total, so both ranks raise
+`ValueError: Free memory on device cuda:N (31.29/31.86 GiB ...)` before a
+single weight loads, twice (2-restart crash loop, zero payload progress). The
+CLI field accepting `le=1` is the trap; Frank's 0.982 is where it always
+ships. What IS reachable from flags: `VLLM_CUDAGRAPH_MEM_BASE_MB` /
+`_PER_GRAPH_MB`, read at call time by `estimate_cudagraph_memory()` — the
+analytic default (256 MiB + 52 MiB/graph) charged 0.55 GiB where the engine's
+own post-capture line reported 0.31 GiB, and a second boot (with the plan
+already charging 0.32 GiB) reported **-0.06 GiB**, so the 256 MiB base pool is
+pure over-charge: shape G charges `0 base + 12 MiB/graph` = 0.07 GiB, which
+still prices per graph for a future 18-graph spec-decode shape (0.21 GiB).
+Verify every deploy by comparing the `Estimated CUDA graph memory`
+line with `Graph capturing finished … took X GiB`; if capture exceeds the
+estimate, raise `_PER_GRAPH_MB` back toward 52. MNBT 1024 → 2048 costs ZERO
+arena: the registry overhead is `base + 0.22 GiB × max(0,(nbt−4096)/1024)`
+anchored at nbt 4096, so every rung ≤4096 charges the same 5.25 GiB — and the
+fitted figure was fitted AT 4096.
+
+**A container's compile cache does NOT survive `podman rm -f`, and on this
+endpoint that is 181 s per boot.** Measured 2026-10-02: the image ships **no
+`/root/.cache` at all** (fresh container: `No such file or directory`); after a
+boot it holds `/root/.cache/vllm` at **1,154,714,333 B in 4,665 files** plus
+`/root/.cache/comgr` at 229 MB, all in the ephemeral layer, and the engine
+prints `torch.compile took 181.20 s in total` (173.19 s of it one graph,
+`Compiling a graph for compile range (1, 1024)`). Every deploy, restart and
+reboot re-pays it. The serve script now mounts
+`FRANK_PRIMARY_CACHE_DIR` at `/root/.cache` — the parent, so the vLLM AOT /
+torch_compile tree (`VLLM_CACHE_ROOT`, whose default is
+`/root/.cache/vllm`) and the comgr HIP-kernel JIT cache both persist, and
+nothing in the image is hidden because the image has no such directory. The
+compile RANGE is part of the cache key, so an MNBT change costs one
+recompilation, not a permanent tax. Same class of fix as the recipe's
+`/cache/{triton,vllm,inductor}` volumes. **Proven live 2026-10-02 on
+consecutive boots:** 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) for compile range (1, 1024) from the cache, took 2.143 s` /
+`torch.compile took 3.97 s in total` / `init engine (profile, create kv cache,
+warmup model) took 41.13 s (compilation: 3.98 s)`. Time to `/health` is
+dominated by the 172.8 GiB payload load, so the visible win is the ~184 s of
+inductor/AOT build, not a proportional boot cut.
+
+Measured 2026-09-29 tuning campaign (fp8 + MTP4 era, since retired): decode
+**37.4-40.6 tok/s, acceptance ~54 %**; the 256k ctx arm measured 34.1-36.5;

+# RUNTIME (2026-10-05, Frank): halogen — the closed-source C++/HIP engine
+# (github.com/peonist-ai/halogen-server, image ghcr.io/peonist-ai/halogen,

+# NVFP4-derivative quant of the BASE Qwen/Qwen3.8-27B (35,865,565,184 B,
+# 1352 tensors), as a podman container under a root unit, driven by

+# 2026-10-02..10-03 ROCmFPX llama.cpp shape (uncensored
+# Q6_0_ROCMFPX_AGENT + MTP, 27.6-28.1 t/s): rollback = revert the swap
+# commit's trio; the ROCmFPX payload, draft head and build all stay on
+# disk at /home/dank/models/kingjones-Qwen3.8-27B-Uncensored-ROCmFP4-STRIX-MTP/.
 #
-# The shape: one session at the model's full native window (262,144), which is
-# the whole point — the Q8_0 head costs quality the fleet wanted back, and
-# the draft head pays for the bandwidth the bigger file spends.
+# WHY THE RUNTIME MOVED WITH THE MODEL: the payload is .hgn — per its own
+# card it "will not load in transformers, vLLM, or llama.cpp". Accepted
+# consequences (Frank, 2026-10-05): TEXT-ONLY (halogen ignores the model's
+# vision encoder; the fleet's vision path is frank-small) and the CENSORED
+# base (this is a finetune of Qwen/Qwen3.8-27B, not the abliterated file —
+# refusals may return). What it buys: vendor-measured decode DFlash2 31.7
+# t/s mean (vs this endpoint's MTP 27.6-28.1 and the old halogen-era MTP
+# 26.9), prefill ~566 t/s at 32k (was ~400 on the sibling engine), 1.4-2.3x
+# wall-clock on prefill-heavy agent traffic, at HIGHER effective precision
+# (~6.32 bpw vs ~6.6 with the old W4A4 promotion — see FLAGS.md).
 #
-# Budget (from the GGUF header, not from a boot log): attention KV lives only
-# in the 16 full-attention layers (4 KV heads x 256 head_dim), 64 KiB/token
-# with f16 K and V => 16.0 GiB at 262,144. The 48 Gated DeltaNet layers hold
-# ~144 MiB of fixed state per sequence. Weights 26.28 + draft head 1.57 +
-# mmproj 0.87 + KV 16.0 + state 0.14 + compute buffers ≈ 45-47 GiB against the
-# iGPU's ~114 GiB GTT aperture, so f16 KV (the unquantized choice) is affordable
-# here in a way it is not on frank-small's 24 GiB card.
+# SHAPE — the two knobs that are NOT free:
+#   HALOGEN_KV_SLOTS=1 KEEPS SPECULATION ON. halogen makes batching and
+#   speculation mutually exclusive: with >1 slot the drafter is disabled
+#   and per-stream decode falls to serial speed (the sibling engine
+#   measured 41 t/s -> 14 t/s when slots were raised, and halogen's own
+#   FLAGS.md prints the same law). frank-large was already a one-session
+#   endpoint under ROCmFPX (PARALLEL=1), so slots=1 is the same contract,
+#   not a regression.
+#   HALOGEN_SLOT_CTX=200700 (Frank's window) is the per-conversation hard
+#   ceiling — a prompt over it is a 400 naming the limit, never a silent
+#   truncation. KV pool = slots x slot_ctx x 64 KiB = 12.2 GiB. Budget
+#   against the 121 GiB of unified memory: weights 33.4 GiB (mmap'd — page
+#   cache, not anon), KV 12.2, engine working set + auto prompt cache
+#   ~20-30, host baseline ~10 -> ~75-85 GiB in use. The 2026-09-16 halogen
+#   era ran the same engine class on this box with LESS headroom.
+#   HALOGEN_DRAFTER=2 (DFlash2) is the shipped default and the fastest
+#   exact drafter on this checkpoint; the .hgn BAKES BOTH drafters (MTP +
+#   DFlash2), so unlike the Flash-Next era there is no sidecar to mount
+#   and no --dflash flag — the drafter is an int knob, byte-identical
+#   output to greedy verification either way.
+#
+# CLIENT CONTRACT deltas vs the ROCmFPX shape (the harness side lives in
+# ~/.omp/agent/models.yml):
+#   * NO server-side sampler defaults: a request without temperature
+#     decodes GREEDY. The harness sends temp 1.0 / top_p 0.95 via
+#     extraBody, so that wire recipe is load-bearing now, not cosmetic.
+#   * max_tokens defaults to 8192 PER REQUEST and INCLUDES thinking; a
+#     reasoning reply over a small budget returns empty content with
+#     finish_reason "length". The harness maxTokens is 57344: compaction
+#     fires at 70% of 200700 = 140,490 and 140,490 + 57,344 = 197,834 <=
+#     200,700 keeps prompt + budget inside the pool (the 262144-era 65536
+#     would overflow). Requests over HALOGEN_MAX_TOKENS_CAP are a 400
+#     naming the cap; cap and queue timeout are COUPLED (see FLAGS.md
+#     table) — do not move one without the other.
+#   * response_format json_object/json_schema is a 400 (no constrained
+#     decoding in this build).
+#   * Thinking lands in reasoning_content — same field as the llama.cpp
+#     era, so the harness compat block does NOT change. reasoning_effort
+#     accepts none|low|xhigh on this build (template default xhigh); the
+#     models.yml fold (high->xhigh) still applies.
+#   * The engine's token protocol has no auth and binds loopback INSIDE
+#     the container; only the frontend port is published. Keep it that way.

-# restorable from the tag.
-#
-# Every number here was QUALIFIED by boot probe on 2026-10-01 (not inherited):
-#   * MAXLEN 241664 x SEQS 3 (724,992 tokens) at bf16 KV is the DEPLOYED
-#     shape (2026-10-01 night ladder): KV_BYTES 10,184,000,000 PER RANK,
-#     engine measured "KV cache size: 732,359 tokens; Maximum concurrency
-#     for 241,664 tokens per request: 3.03x". 262144 and 245760 both OOMed
-#     at graph capture (76 MiB short / 0 bytes free); 237568 passed at
-#     718,606 tokens and the +4096 bonus step passed and won.
-#   * KV_BYTES is PER RANK. The old "7.2 GiB ceiling, 9/16 GiB OOM" law was
-#     the MTP4 WORKSPACE: the spec-era pool measured 729,545 tokens because
-#     the drafter reserved ~2.6 GiB/rank beside the pool. No-spec bf16 takes
-#     11.05 GiB/rank and boots clean — the ceiling was spec's, not VRAM's.
-#   * bf16 KV doubles the attention-KV bytes/token (measured 14,047 vs
-#     7,926) and costs ~14% decode vs fp8 at 4064 ctx (49.25 -> 36.42 with
-#     the gather win) — traded deliberately for clean cache + 262k windows.
-#   * GATHER 32x64 is the night's biggest lever: R4D_LRU_GATHER_CHUNKS=32 /
-#     R4D_LRU_GATHER_LANES=64 measured +18.7% decode vs default geometry,
-#     and the win grows with depth (39.5@166 -> 54.1@1087 -> 49.3@4064 fp8
-#     era). Do not drop it.
-#   * MNBT 1024 is Frank's lock: MNBT 512 doubles TTFT at 4064 ctx (2.46 s
-#     vs 1.36 s); 1024-4096 are interchangeable on decode; 12288 costs 2.5%
-#     and arena. 1024 keeps the workspace floor so the arena stays max.
-#   * PREFETCH IS ABSENT BY LAW: expert-cache telemetry measured the
-#     prefetcher at 36% precision (36,720 slabs prefetched, 13,369 served) —
-#     roughly half the gather traffic was waste. Never re-add
-#     --expert-prefetch without a fresh A/B.
-#   * TunableOp stays OFF: CLAV_TUNABLEOP_SWEEP silently skips under expert
-#     offload unless CLAV_TUNABLEOP_WITH_OFFLOAD=1, and forcing it corrupts
-#     numerics.
+# 2026-10-03 shape G (as shipped, after the 1.00 revert): the CUDA-graph plan
+# term dropped from the analytic 0.55 GiB to the measured 0.07 GiB (0 base +

+# 17.77 GiB / 7,762 slots, KV 401,408 tokens / 2.00x concurrency (the first
+# shape holding two full-length conversations with real spare), driver used
+# 30.97 GiB of 31.86 — 0.89 GiB of real free VRAM per card, held through a
+# live 4,096-token generation. UTIL stays 0.982 ALWAYS: 1.00 is unbootable on
+# this fork (worker init refuses budget >= device total) and 0.13-GiB-margin
+# boots die under load.
+# `budget - non-expert - KV reserve - graphs - overhead` and the KV reserve is a
+# registry constant, so those two terms are the whole flag surface.
+# 2026-10-03 shape F (absorbed): MNBT 2048 + the graph term pinned. Measured on
+# the live deploy: arena 17.52 GiB / 7,653 slots, budget 31.29, graphs 0.32.
+# 2026-10-02 shape E: fp8 KV, MAXLEN 200704 x SEQS 3, pool 3.15e9/rank, and
+# --expert-precise-memory ON. The window shrink from the native 262144 and the
+# --max-num-seqs 3 lock both come from shape D (SEQS=2 CANNOT boot this model —
+# the measured 2x2 is below); shape E adds the precise-overhead plan, which
+# trades the default 7.60 GiB compile headroom for the fitted 5.25 GiB and puts
+# the 2.35 GiB difference into the expert arena: 6,496 -> 7,522 slots (+16%).

+# model_runner.py sizes that input buffer max_num_reqs + 1 and _dummy_run sets

+# SEQS + 1 for ANY MNBT >= SEQS: 3 at SEQS 2, 4 at SEQS 3. MNBT only moves the

+# why MNBT is not a lever here. --enforce-eager bypasses the path but loses

-# KV_BYTES is PER RANK. fp8 costs 7,701 B/token (measured 6,138 attention

-# -> 3.091e9 B floor, pinned at 3.15e9 (~405,000 tokens, ~44 MB margin —
-# the same margin convention the 6.1e9 shape used).
+# THE ARENA LEVER IS max_model_len, NOT KV_BYTES (measured 2026-10-02). The
+# planner sizes expert cache as budget - non-expert - KV reserve - graphs -
+# overhead, and the KV reserve is registry-priced at 9190 B/token x max_model_len:
+#   MAXLEN 262144 -> reserve 2.48 GiB -> arena 14.30 GiB / 6,248 slots
+#   MAXLEN 200704 -> reserve 1.91 GiB -> arena 14.87 GiB / 6,496 slots
+# d(reserve) 0.57 GiB = d(arena) 0.57 GiB = +248 slots. The 6.1e9 -> 3.15e9
+# pool cut buys ZERO arena; it buys runtime HEADROOM (the shape it replaced
+# died with 0 bytes free on a real 995-token request). To grow the arena,
+# lower MAXLEN — not KV_BYTES. The OTHER arena lever is the overhead term:
+# --expert-precise-memory (shape E) takes it from 7.60 to 5.25 GiB and lands
+# those 2.35 GiB in the arena — 14.87 -> 17.22 GiB / 6,496 -> 7,522 slots.
 #
-# THE ARENA IS WHAT REMAINS: the fork's expert planner sizes it AFTER the
-# KV override, so every byte cut here is arena. The 6.1e9 shape ran an
-# arena of 6,248 slots; this one reclaims ~2.95 GiB/rank, roughly 1,260
-# more slots at 2.344 MiB each. That is the point of the change — the

-# more experts resident instead of streamed.
-#
-# MNBT 1024 (down from 2048): 1024-4096 are interchangeable on decode AND
-# identical on arena (the sweep measured the same slot count at every

+# Do not drop it.
+# CHUNKED PREFILL: the fork exposes the standard scheduler flags. --max-num-batched-tokens

+# and --prefill-schedule-interval is the gap between iterations. The running shape carries

+# One physical SSM slot, two heads, BOTH ranks (heads 3 and 8), 23 layers
+# each. The guard's own message in this build: "known Qwen3.8-Flash-Next
+# (QFN) flaw under prefix caching and is being actively worked; output
+# quality for this request may degrade. Mitigation:
+# --no-enable-prefix-caching".
+# MECHANISM: with prefix caching on, this fork puts QFN on
+# mamba_cache_mode 'align' (the default-for-this-arch branch in
+# config/vllm.py; 'all' is deprecated and 'none' is the no-prefix-cache
+# mode, so align is the only sound mode WITH the flag). Align mode
+# checkpoints each sequence's GDN (Gated DeltaNet) recurrent state into a
+# mamba page every block, where block = 3136 tokens (the attention block
+# size is raised to 3136 so the page sizes match exactly — the boot log's
+# "Padding mamba page size by 0.13% ..."), and RE-SEEDS the state from that
+# page whenever a request resumes from a cached prefix. The corrupt state
+# landed at the 13th boundary: 13 x 3136 = 40,768 tokens — the "~40k" mark
+# where the request's output turned repetitive/corrupted. The NaN stayed
+# in the mamba page, so every later turn of that conversation re-seeded the
+# same non-finite state for those two heads (silent: the fault-report cap
+# was already spent), while fresh short sessions looked fine.
+# RAM WAS "RULED OUT" THE SAME DAY — AND THAT WAS WRONG (RESOLVED below).
+# What the evidence actually supported: zero MCE/EDAC records is the
+# EXPECTED silence of consumer non-ECC memory (a silent flip raises no
+# machine check); an 8 GiB pattern check over 60 s covers ~0.5 % of
+# 246 GiB — no verdict on a speed setting; "4800 is the JEDEC floor on
+# 5600-rated DIMMs" is a rating, not a stability proof at four-DIMM
+# loading. Only the two-head NaN signature argument was load-bearing,
+# and the revert test outvoted it.
+# COST ACCEPTED: no prefix reuse, so each turn re-prefills the whole
+# history instead of at most 3135 tail tokens (a full 40k context costs
+# tens of seconds of TTFT per turn at this shape's prefill rate). A silently
+# corrupted conversation is worse than a slower first token.
+# RESULT (2026-10-05, later that day): THE MITIGATION DID NOT WORK. With
+# --no-enable-prefix-caching deployed and mechanically verified (zero
+# gdn_hip faults, a 40,771-token single-request boundary probe coherent),
+# live long conversations STILL degraded at ~40k on the running endpoint
+# (Frank, direct). The container serving that window logged ZERO faults
+# while the corruption reproduced, so the align-mode page re-seed is not
+# the (only) mechanism — see the runbook's RESULT note for the open
+# hypotheses (re-fed poisoned transcript vs a fault-free long-context
+# path such as fp8 KV at depth). Cost bought nothing: caching is back ON.
+# The knob stays commented for a future fork build with a fixed GDN state
+# path: set 1, redeploy, re-verify past 40,768 tokens (one conversation
+# coherent AND zero gdn_hip lines).
+# RESOLVED 2026-10-05 EVENING (Frank): IT WAS THE RAM. 4800 MT/s (in
+# effect since the 2026-10-04 17:17 boot) was marginal; 4600 MT/s (since
+# the 2026-10-05 12:21 boot) and the endpoint is clean — zero gdn_hip
+# ERROR lines, zero MCE, and the live agent session on it past 140k
+# context with no degradation. Both failure eras sit under the RAM: the
+# 2026-10-04 NaN burst (corrupted weight/activation traffic poisoning a
+# GDN state write — the guard-visible path) and the fault-free ~40k
+# degradation (silent flips in KV/expert data, which no guard covers on
+# non-ECC). CONSEQUENCE FOR THE KNOB: the OFF experiment was CONFOUNDED
+# — both arms ran on the marginal speed — so it neither proved nor
+# disproved the fork's align-mode flaw. Prefix caching stays ON (zero
+# gdn_hip lines under heavy re-send traffic since the speed drop); flip

+# pool step fits BOTH the 2-3 GiB floor and the harness compaction

+# Compute-buffer geometry. This endpoint passed neither flag until 2026-10-03,
+# so it ran on llama.cpp's own defaults (2048/512); the pair is now 4096/2048.
+# Both are tunables because the pair is a measurement, not a law — and the
+# measurement is CARD-SPECIFIC. On the 2x R9700 layer-split sibling the ubatch
+# curve peaks at 512 and every step up costs GiB of compute buffer for no
+# speed (see frank-medium-batch-ubatch). On THIS CUDA 3090 the curve climbs
+# monotonically to 2048: 710 -> 1188 t/s prefill from ubatch 1024 to 2048 on
+# the 35B MoE sweep, 1944 -> 2423 t/s on the Ornith 8k sweep, with decode flat
+# to under 1 t/s on every rung. Ubatch is a prefill knob; decode never moves.
+#
+# The logical batch is free — two independent sweeps agree that at a fixed
+# ubatch, 2048/4096/8192 give identical prefill speed AND identical peak VRAM,
+# because the compute buffers are sized by the ubatch alone. Doubling it costs
+# nothing and buys nothing; it is here because it is the value the pair was
+# measured at.
+#
+# THE RISK IS ALL IN THE UBATCH. The 1024 -> 2048 step cost ~1,244 MiB of peak
+# graph VRAM on the 35B MoE (7,330 -> 8,574 MiB); this 9B hybrid has far
+# smaller compute tensors, so the delta should be well under that, but the
+# predecessor Q5_K_M shape recorded "ubatch 2048 failed the scratch boot" at
+# ~3,571 MiB free. The Q8_0 rung ships UBATCH 1024 (Frank, 2026-10-05: lower
+# ubatch FIRST — the measured 616 MiB step is the first VRAM the Q8 weights
+# claw back, before any pool move). Compute buffers are allocated at graph
+# capture during BOOT, so a failure is loud and fast, not a surprise at the
+# first long prompt. MEASURE nvidia-smi free immediately after the deploy:
+# under ~1.5 GiB, or a boot failure, step the POOL down next (12,288-token
+# increments, ~432 MiB each at the Ornith 36 KiB/token f16 KV rate).

 #
-# 2026-10-02 (Frank): swapped from gufo + Q4_K_XL to the highest-quality file
-# in the repo, one session at the native 262,144 window.
+# The engine is driven by `podman run` DIRECTLY (the fleet's frank-primary
+# pattern): the image entrypoint `halogen-docker` in default "all" mode
+# starts engine + OpenAI frontend in one container. The frontend listens on
+# 8731 inside (HALOGEN_API_PORT default) and is published as host 7770; the
+# engine's own token port (8730, no auth) stays unpublished on the
+# container's loopback. The image ships NO default checkpoint:
+# HALOGEN_CHECKPOINT selects the file inside the /models mount.
 #
-# Why this runtime and not the previous one: the payload is ftype 115 — 311
-# tensors of GGML_TYPE_Q8_0_ROCMFPX (103), a tensor type that exists only in
-# the ROCmFPX fork. Stock llama.cpp, SGLang and gufo all refuse the file, and
-# gufo additionally gates every "Qwen3.8" artifact on a template-hash
-# allowlist. The qualified build is scripts/build-rocmfpx.sh's pin: it loads
-# ftype 115, survives warmup (the 2026-08-25 builds of the older fork line
-# segfaulted in ggml_compute_forward_set_rows on this exact file), and drafts
-# with the model's own MTP head.
+# Gates mirror the deployer EXACTLY (the 2026-10-01 crash-loop lesson —
+# serve gate and deploy gate disagreeing = green deploy, red unit):
+# tokenizer directory present with every named file a FLAT REGULAR FILE —
+# the model card ships `tokenizer/` as a flat directory and the engine
+# defaults HALOGEN_TOKENIZER to /tokenizer, so a HF cache snapshot's
+# symlinks into blobs/ dangle inside the mount; GPU device nodes present.
 #
-# Why this file: Q8_0_ROCMFPX_AGENT is the top of the repo's quality ladder
-# (26.28 GiB, 8.39 bpw) and the AGENT routing keeps 187 tensors — the
-# output-head set the draft scores against — at plain Q8_0 instead of the 2
-# the non-AGENT build keeps, which is the variant the card names for MTP
-# serving. Drafting uses the repo's Q4_0 MTP head: the head's cost is its
-# projection over the 248K vocabulary, so the 4-bit head is faster end to end
-# at equal-or-better acceptance than its Q8_0 sibling.
-#
-# The client contract lives here, not in frank-large.env:
-#   * --jinja — without it llama.cpp silently IGNORES the harness's
-#     chat_template_kwargs (enable_thinking / preserve_thinking), so the
-#     endpoint would look like it had no thinking control at all. The GGUF
-#     carries the official Qwen template, so no --chat-template-file.
-#   * --reasoning-format deepseek — thinking is emitted as reasoning_content,
-#     the field the harness reads for this endpoint.
-#   * the template accepts reasoning_effort xhigh|medium|low only, which is
-#     why models.yml folds the harness's levels onto that set.
-#   * --alias frank-large — that is the model id the harness resolves.
-#   * --ctx-checkpoints / --cache-ram — prompt-cache geometry for the 16
-#     sliding-window-style layers; harmless where the hybrid state forces a
-#     full re-process, and required for the checkpoint feature to work at all.
+# Why containers instead of the bare binary (the old frank-large shape):
+# the payload is .hgn and only halogen reads it; halogen ships as a
+# container; the root unit keeps LimitMEMLOCK=infinity for parity and to
+# outlive the login session, exactly like frank-primary's.

 The DFlash drafter proposes, then ngram-mod runs as an additional implementation in the chain. Verified against upstream `common/speculative.cpp` (b10133+).
 
+### Chaining laws (measured on this fleet, 2026-09 → 10)
+
+`--spec-type` takes a comma list, and the gate is `ctx_dft` in
+`common/speculative.cpp` (`common_speculative_init_result`): **draftless**
+types (the ngram family — simple, map-k, map-k4v, mod, cache) are added
+unconditionally, while **context-backed** types (`draft-mtp`, `draft-dflash`,
+`draft-dspark`, `draft-eagle3`) all require a draft CONTEXT. Consequences:
+
+- A chain may hold ONE context-backed drafter plus any number of ngram types.
+  `draft-dflash,ngram-mod` is legal and measured: 2.6x the drafter alone on
+  prompt-echo traffic, byte-identical to it on prose at the fleet's 48/64
+  window.
+- Two context-backed types cannot share one process: `draft-mtp,draft-dflash`
+  dies at load with `context type MTP requested but model doesn't contain MTP
+  layers` — MTP builds its context against whatever the draft context holds,
+  so it met the DRAFTER's file, not a missing head. Pin that in a seam so
+  nobody "fixes the flag" later.
+- Internal order is fixed (ngram types first, then drafters); CLI order is
+  irrelevant.
+- **A legal chain can still lose on a recurrent model.** `draft-mtp,ngram-mod`
+  on the qwen35 hybrid (frank-large era) measured −15 % prose / −7 %
+  block-copy (2026-10-03): adding the ngram layer logs `recurrent state
+  rollback is not compatible with 'ngram-mod' - disabling rollback support`,
+  and MTP verification depends on that rollback, so acceptance drops on ALL
+  traffic even where the matcher fires. Measure chains per architecture,
+  never by analogy.
+- ngram-mod prints NO startup banner — the load log shows only the drafter's
+  `adding speculative implementation` line. Never conclude "chain not
+  engaged" from the load log; identify behaviourally (`draft_n` > 0 only
+  where text repeats) or by the per-task `draft acceptance = ... mean len`
+  line. It costs ~64 MiB of host-RAM hash table.
+
+### Drafter KV: read the window policy from the header
+
+The draft context is built with `cparams.n_ctx = llama_n_ctx(ctx_tgt)`
+(`common/speculative.cpp`) — there is no flag to cap it — so a drafter that
+declares NO sliding window caches the whole target window on whatever device
+`--spec-draft-device` names. DFlash declares `sliding_window = 2048` (~40 MiB
+of draft KV); DSpark declares none: 5 layers x 2 x 8 kv heads x 128 dim x 2 B
+= 20 KiB per position, i.e. **5.0 GiB at 262144** — enough to kill the first
+draft graph capture with `ROCm error: out of memory` AFTER the model loaded
+and `/health` answered (measured 2026-09-16). Read `sliding_window` out of
+the drafter's GGUF header before sizing any spec-decode deployment, and
+prefer a skewed `-ts` over a context cut when the full window matters.

 History: before `--spec-default`, the box ran DSpark (`draft-dspark`, retired 2026-08-15 after a ROCm illegal-memory-access crash under two concurrent 16k prompts) and before that bundled MTP (`draft-mtp`, retired same day).

+## A/B protocol on a live llama.cpp endpoint
+
+Verdicts are **traffic-shaped**: a proposer can only draft text it has seen,
+so a single prompt shape answers the wrong question. Use fixed shapes:
+
+| Shape | Prompt | Who it can favour |
+|---|---|---|
+| prose | 1k filler + "reply with one sentence" | model-backed drafters only |
+| echo | ~1.5k passage of UNIQUE lines + "repeat verbatim" | ngram (output IS the prompt) |
+| structured | repetitive output, no prompt overlap | ngram, if spans really repeat |
+| identity | short deterministic question | controls for lossless verification |
+
+Design the echo passage so no long span repeats INSIDE it — otherwise you
+measure the matcher against itself. For `structured`, give each line a unique
+id: repeated lines make it a negative control, not a repetition test.
+
+Protocol:
+
+1. Stop the unit (`sudo systemctl stop <svc>`), `pkill -x llama-server`; wait
+   for the port (a retired predecessor's published-port proxy leaves the
+   endpoint port in TIME_WAIT — the bind fails with address-in-use long after
+   the unit stopped).
+2. Per config: write an env file with the overrides, start the serve script
+   with `FRANK_*_ENV_FILE`, poll `/health`, measure. Ready-made harness:
+   `scripts/bench-spec-ab.py <env-file> <serve-script>`.
+3. **Restore the unit in a `finally`** and shout if it does not come back
+   healthy. A crashed harness that leaves production down is worse than no
+   harness.
+4. **Prove losslessness**: one fixed prompt at temp 0 to every config, diff
+   the greedy text. Speculation only buys speed; differing texts are a
+   correctness bug. Empty answers (`content: null` when reasoning ate the
+   budget) make the comparison vacuous — bench clients must fall back to
+   `reasoning_content`, and echo/structured prompts should disable thinking
+   per request: `chat_template_kwargs: {"enable_thinking": false}`.
+5. **Sweep the depth, not just the mode** — draft depth is model-specific and
+   single-valued; deeper often loses (measured: at n=7 a third of proposals
+   survived, at n=3 more than half).
+6. **Sweep the ngram window in the same run as the configs**: too short a
+   `--spec-ngram-mod-n-min/-n-max` proposes on ordinary prose fragments —
+   rejected, verification still paid (measured 43.9 → 36.0 tok/s).
+
+Read the right counters — per request `timings.draft_n` / `draft_n_accepted` /
+`predicted_per_second`; cumulative `/metrics`
+`llamacpp:spec_decode_num_drafts_total` / `..._accepted_tokens_total`;
+per-task `draft acceptance = ... (N accepted / M generated)`. `draft_n == 0`
+while tokens flow = the proposer is NOT engaged, whatever the flags say. A
+zero-draft config is a useful negative control: it proves the other config's
+drafts came from the proposer under test.
+
+Harness hygiene: absolute script paths (a relative path plus `cd` to its own
+dir double-counts the prefix); `pkill -x`, never `-f` (the pattern matches
+your own command line); nested f-strings with backslash escapes are a
+SyntaxError on the fleet's Python (<3.12 semantics) — build log lines with
+concatenation. Report `decode tok/s` per shape plus acceptance and mean
+accepted length; a config that wins on echo and loses on prose is a traffic
+decision, not a winner. Wire the winner into the deployed env file with the
+measured table as its justification comment; record losing numbers with "do
+not switch without re-measuring".
+
+The A/B vehicle for ANY single-GPU llama.cpp knob (batch/ubatch, KV type,
+slot split, quant rung — not just spec flags) is the transient systemd
+drop-in procedure in [[frank-large-benchmark]] and [[frank-small-benchmark]].
+
+## Is it worth it? (arithmetic before deployment)
+
+Answer against the INCUMBENT, not against zero.
+
+**Step 0 — check whether the target already speculates.** Many engines ship a
+drafter of their own; then your baseline is `A_incumbent / t_s`, not `1 / t_s`.
+halogen-flash-server: MTP head ON by default — read its own accounting, e.g.
+`serve_api: mtp 63 tok in 1.31s = 47.97 t/s | 33 rounds, commit 1.88/round`.
+llama.cpp: `/metrics` counters and per-request `draft acceptance` lines.
+
+**Step 1 — measure the two step times, never guess.** Target step `t_s` = 1 /
+(client-visible tok/s ÷ commit-per-round); ask for the rate the operator
+actually SEES (engine-internal decode-only numbers run ~1.7–2x optimistic).
+Drafter step `d_s` from llama.cpp's per-task `eval time` lines when it is a
+plain model on the same box.
+
+**Step 2 — arithmetic:**
+
+```
+round_time = K * d_s + 1.1 * t_s        # K drafts proposed, K+1 verified in ONE target pass
+A          = (1 - p^(K+1)) / (1 - p)    # expected accepted tokens, p = per-position acceptance
+rate       = A / round_time             # compare to the incumbent
+break-even : A > rate_incumbent * (K*d_s + 1.1*t_s)
+```
+
+Worked example that decided a real case: `t_s = 67 ms` (25 tok/s, 1.67
+commit/round), `d_s = 12 ms` (27B IQ3_S drafter on the 3090) → break-even
+`p ≈ 0.70` at K=3, `≈0.68` at K=5; a realistic cross-finetune `p = 0.4–0.6`
+gives 17–20 tok/s, i.e. a LOSS. A drafter only ~3x faster per token cannot
+pay for K sequential forwards.
+
+**Step 3 — classify the drafter by per-round cost:**
+
+| drafter | cost per round | needs |
+|---|---|---|
+| plain model (`-md`/`draft-simple`) | **K sequential forwards** | 10–50x faster than the target |
+| n-gram / prompt-lookup (`ngram-*`) | ~0, no model | repeated context (agent edit loops) |
+| trained head (`draft-mtp`, EAGLE/DFlash) | **~1 pass** | the head must exist FOR THAT CHECKPOINT |
+
+Trained heads are target-specific: EAGLE/DFlash consume the TARGET's hidden
+states, so a dense-27B DFlash2 is useless for a 512-expert MoE trunk.
+
+**Step 4 — acceptance reality checks.** Fleet datum: a trained z-lab DFlash2
+at depth 7 accepted ~41 % on its matched target (`draft-dflash 7 → 43.5
+tok/s`); treat 40–60 % as the honest band for a matched pair. Cheapest proxy
+for `p` at temp 0 when both models are greedy and share a tokenizer: greedy
+continuation agreement on identical prompts, two API calls, no weights moved.
+llama.cpp can also synthesize the projection without any draft artifact:
+`--spec-synth-rates P0,P1,...` / `--spec-synth-len L`. Speculation pays IN
+PROPORTION TO HOW SLOW THE TARGET IS — the same 41 % gave 2.3x on an
+18.8 tok/s layer-split target and a loss on a 25 tok/s one; fast targets are
+usually sparse MoE, the worst case for drafting.
+
+**Step 5 — check the attachment surface BEFORE the arithmetic.** Closed
+engines refuse external drafters by design: halogen-flash-server's
+`DRAFTER_CAP` gates `dflash2` on the loaded checkpoint and an unavailable
+name is a deliberate 400 (a silent downgrade would make comparisons lie);
+there is no device routing in its loopback token protocol, so a drafter can
+never sit on another card. Pure llama.cpp DOES route the draft:
+`--spec-draft-device/-devd` (default follows `--device`), `-ngld`,
+`-otd`, `-ctkd/-ctvd`, `--spec-draft-n-max` (default 3), `--spec-draft-p-min`.
+One process sees only the devices its backends were built with — CUDA+Vulkan
+is the combination that shows a CUDA card AND an AMD iGPU (HIP+CUDA cannot
+coexist); a CUDA-only build has no `Vulkan0` to draft with.
+
+**Step 6 — cross-model pairs need a byte-identical tokenizer.** Speculation
+compares token IDs, so draft and target must map id → same string. Verify
+cheaply from the GGUF headers (first ~8 MB over HTTP, no full download):
+parse `tokenizer.ggml.tokens`, print vocab size, merges, `pre`, and sha256
+over the first 2000 tokens —
+
+```
+vocab=248320 merges=247587 model=gpt2 pre=qwen35
+sha256(first 2000 tokens)=8619c68fe4466d3a   # identical => ids are interchangeable
+```
+
+Identity is necessary, NOT sufficient — the drafter still has to be cheap and
+accepted. Report in this order: does the target already draft; break-even
+`p` at K=1,3,7 versus the incumbent; the realistic band and resulting rate;
+whether the drafter fits (VRAM) and the attachment surface exists; the one
+measurement that would settle it.

+
+# GGUF Compatibility and Runtime Lock-in
+
+**The law: a GGUF's tensor-type histogram and ftype pick the runtime — read the
+header before promising a file to any loader.** Stock llama.cpp, Ollama and LM
+Studio refuse custom types at load (`unknown tensor type`); a fork-private type
+means exactly one engine can serve the file. Measured on this fleet repeatedly:
+`Qwen3.8-27B-Q8_0_ROCMFPX_AGENT.gguf` is ftype 115 with 311 tensors of type 103
+(`GGML_TYPE_Q8_0_ROCMFPX`) — only charlie12345/ROCmFPX reads it. The full type
+tables live in [[Llama Cpp Runtimes]] and [[Llama Cpp Code Diff]]
+(ggml_type 100–108, ftype families 100–106 / 110–113 / 118).
+
+## 1. Read the header, do not guess
+
+Parse the GGUF KV section and histogram the tensor types plus
+`general.architecture.file_type` — one python read over the first few MiB, no
+model load. Counting types out of the KV section settles a runtime argument in
+minutes; repo names and model cards do not.
+
+## 2. Compare routing variants by tensor mix, not by name
+
+Two files of the same quant can differ in how many tensors stay at plain Q8_0
+(measured: 187 vs 2 output-head tensors in an `_AGENT` variant of the same
+size). That difference is what moves spec-decode acceptance (0.953 vs 0.911)
+— the "same size" file is not the same file.
+
+## 3. Pin the build by commit SHA
+
+A fork that can read the file today can still crash mid-load: the 2026-08-25
+ROCmFPX builds read the ftype-115 file and then SIGSEGV in
+`ggml_compute_forward_set_rows`. Record the SHA in the build script
+(`scripts/build-rocmfpx.sh` pins `36e9acd`) and check it out explicitly — never
+a branch.
+
+## 4. Header diff method (candidate vs known-good)
+
+Answer "will engine X load this GGUF?" by diffing the candidate's header
+against a file the engine **already loads** — never by filenames or model cards;
+filenames lie about quantization and about MTP/vision heads.
+
+1. **Get the bytes**: both files, from byte 0, at least 64 MiB. Tokenizer KVs
+   (151k token strings + merges) routinely eat 5–8 MiB, so a small range
+   desynchronises the parser. True size from `curl -sIL` → `x-linked-size`
+   (a bare HEAD `Content-Length` can lie):
+
+   ```sh
+   curl -sL -r 0-67108863 -o cand.bin \
+     "https://huggingface.co/<owner>/<repo>/resolve/main/<file>.gguf"
+   ssh <host> 'head -c 67108864 /path/to/known-good.gguf' > good.bin
+   ```
+
+2. **Parse — and lock the parser against the known-good file first.** Layout
+   (v2/v3): `magic[4]` `version u32` `n_tensors u64` `n_kv u64`, then KVs, then
+   tensor infos. Strings are u64 length + bytes. **The value-type enum is NOT
+   llama.cpp's `gguf.h`:** in the files seen (2026-09-28, unsloth + ajgazin UD
+   GGUFs) type **8 = STRING, 9 = ARRAY**; llama.cpp's header has STRING=2,
+   ARRAY=3 and desynchronises immediately. Working table:
+
+   ```
+   0 u8   1 i8   2 u16  3 i16  4 u32  5 i32  6 f32
+   7 bool 8 STR  9 ARRAY(u32 et, u64 n)  10 u64  11 i64  12 f64
+   ```
+
+   Validate before trusting: the parse is right iff the tensor-info block ends
+   somewhere sane and names look real (`blk.0.attn_q.weight`,
+   `token_embd.weight`, `output_norm.weight`). EOF throw = wrong enum or
+   offset — do not work around it.
+
+3. **Diff what engines actually bind on**: `general.architecture`; tensor
+   count; tensor name list in order; per-tensor `ggml_type` and dims; geometry
+   KVs (`<arch>.block_count`, `.embedding_length`, `.feed_forward_length`,
+   `.attention.head_count[_kv]`, `.rope.*`, `.ssm.*`, `.context_length`,
+   `.nextn_predict_layers`); MTP tensors (`nextn` in the name); vision tensors
+   (`visual`, `v_` prefixes). A same-family fine-tune quantized by the same
+   tool usually comes out byte-identical in every one of these — that is the
+   answer.
+
+4. **Then read the engine's source before calling a delta a blocker.** A
+   metadata difference only matters if the engine reads that key
+   (`grep -rn "file_type\|recurrent_layers\|full_attention_interval" <src>/`).
+   Worked example (gufo v0.1.1): `general.file_type` is deliberately not
+   consulted (UD-*_K_XL ships a stale ftype 15; the tensor table rules), and
+   `qwen35.attention.recurrent_layers` is never read (layer kinds come from
+   `full_attention_interval`) — both deltas were non-issues the header diff
+   alone would have flagged wrongly.
+
+5. **Say what you did not do.** Header analysis is strong evidence, not a
+   load. State byte sizes, check free disk before proposing a fetch, and do
+   not download tens of GB unasked — pointing the engine at the file is the
+   definitive test.
+
+**Report shape:** verdict first (loads / will not / loads-with-caveats), then
+the side-by-side diff table, then only the load-bearing caveats: text-only vs
+vision tensors, chat-template differences (matters for llama.cpp, not for
+engines with compiled-in Jinja), license, disk headroom, and whether the base
+model is abliterated/uncensored.
+
+## 5. A/B a fork's spec decode by stripping the whole flag set
+
+`--model-draft` without `--spec-type` segfaults at load (measured 2026-10-02,
+core dump, no diagnostic). A baseline "no-draft" arm must remove `--model-draft`
+AND every `--spec-draft-*` AND `--spec-type` together — the flags move as a set.
+
+## 6. Before deleting a retired payload, read the rollback tag's env file
+
+A rollback may need a small companion dir: a drafter living in a directory
+named after an old quant looks like trash but is load-bearing. Same class as
+the gufo payload removal of 2026-10-03, which turned that rollback into a
+re-download.

+
+# Llama Cpp Multi-Device Splits
+
+## 1. Expressibility law — classify the arrangement before running anything
+
+llama.cpp expresses exactly two things across devices, and they are not
+interchangeable:
+
+| arrangement | how | expressible? |
+|---|---|---|
+| **Layer split** — layers 0..n on dev A, rest on dev B | `-sm layer -ts <a>/<b>` | **yes**, no collectives needed; works cross-vendor (CUDA + Vulkan measured 2026-09-16) |
+| **Per-tensor placement** — attention+KV on A, experts on B | `-ot <regex>=<dev>` | **NO.** `--override-tensor` sets `has_tensor_overrides()`, a REQUIRED term of the scheduler's `pipeline_parallel` flag (only read site: `llama-context.cpp`, in the `pipeline_parallel = …` expression). That flag sets `n_copies = parallel ? MAX : 1` in `ggml_backend_sched_new`; with `n_copies == 1` a pre-allocated weight on a non-primary device has no backend and the graph aborts at `ggml-backend.cpp:941` (`pre-allocated tensor (blk.0.ffn_down_exps.weight) in a buffer (Vulkan1) that cannot run the operation (NONE)` — `(NONE)` is the leaf's own op name). |
+
+Failure modes observed (mainline `37b53fd`): per-tensor `-ot exps=Vulkan1`
+with `-dev CUDA0,Vulkan1` → scheduler abort; layer-scoped `-ot` with a
+cross-backend pair → model load fails with only `failed to load model`;
+`-ot x=CPU` **works** because the CPU backend is last in the list — **the CPU
+is the only legitimate partner in a heterogeneous split.** On a CUDA+AMD host
+a card can be the trunk OR the offload host, never the complement of an
+AMD-resident peer. Pure Vulkan changes nothing here — the gate is the
+override, not the driver mix.
+
+If the plan needs tensors on a specific device: stop, the answer is no for
+any vendor mix. Expressible alternatives, in order: (1) two independent
+endpoints, one model per device; (2) single-vendor layer split; (3) device +
+CPU per-tensor offload (mainline pinning guard: `GGML_CUDA_NO_PINNED`; ik fork
+was `GGML_CUDA_NO_PINNED_WEIGHTS` — without it a CPU-overridden tensor can
+land in a pinned `CUDA_Host` buffer and page-lock ~108 GiB).
+
+Layer-split arithmetic to check before promising: a whole layer carries its
+experts (MoE) — compute GiB/layer, not per param-group; only some layers carry
+KV (every 4th on the hybrid), so a share of layers is only a share of KV; big
+non-repeating tensors (PLE tables) land on the main device and cannot move —
+they cap how small the primary can get.
+
+## 2. No collectives? The atomics wall and the layer-split answer
+
+Decide with one line before designing:
+
+```bash
+sudo lspci -vv -s <card2> | grep AtomicOpsCtl   # ReqEn- ⇒ no collectives, ever
+lspci -tv                                        # a Routing- bridge is a hardware wall
+```
+
+`ReqEn-` kills vLLM entirely — TP needs a per-layer allreduce AND PP needs a
+device-backend `send`/`recv` of the hidden state
+(`vllm/distributed/parallel_state.py`) — i.e. the same RCCL primitive that
+fails on an atomics-less card. llama.cpp's `--split-mode layer` needs no
+collective: layers distribute in order, only the boundary activation crosses
+PCIe once per forward pass. Full probe/repair detail:
+[[PCIe Link and Atomics]].
+
+## 3. Build: pin by feature, bundle the runtime at the exact depth
+
+- Pin the ref by FEATURE list (e.g. DFlash2 + qwen35 MTP on 2026-09-16 →
+  `ggml-org/llama.cpp#27342`); never float. Verify a fork build the same way
+  (`ls <venv>/…/spec_decode/ # dflash/ vs dflash2/`).
+- `-DCMAKE_HIP_ARCHITECTURES=<gfx only>` — a sibling arch links, loads, then
+  segfaults. `-DGGML_HIP_RCCL=OFF` when there is no atomics path (only tensor
+  mode degrades to the butterfly fallback; layer split unaffected).
+- **TRAP — `cp -r SRC DST/` flattens when `DST` does not exist** and drops one
+  directory level. rocBLAS/hipBLASLt look for device code at a FIXED depth
+  (`../lib/rocblas/library`, `../lib/hipblaslt/library/<arch>`); flattened,
+  the engine loads every GiB, answers `/health`, and dies on the FIRST request
+  with `Cannot read .../TensileLibrary.dat: No such file or directory for GPU
+  arch`. `mkdir -p DST && cp -r SRC/. DST/`, then
+  `patchelf --set-rpath '$ORIGIN/../lib' build/bin/llama-*`.
+- Dual-backend build (CUDA + Vulkan is the practical pair; HIP+CUDA do not
+  coexist): `-DGGML_CUDA=ON -DGGML_VULKAN=ON` in one tree; Vulkan needs
+  `glslc` + libvulkan headers. **Device names are not what you expect:**
+  `--list-devices` lists the discrete card under BOTH backends (`CUDA0` AND
+  `Vulkan0`) and the APU LAST (`Vulkan1`) — a wrong `-ot` name makes
+  llama.cpp print the valid set and exit (self-diagnosing).
+- What the existing build can do: `GPU_BACKEND_*=OFF` lines in its
+  CMakeCache.
+
+## 4. Serve flags that matter on a split
+
+```bash
+HIP_VISIBLE_DEVICES=0,1 llama-server \
+  --device ROCm0,ROCm1 --split-mode layer --tensor-split 1,1 \
+  --gpu-layers 999 --fit off --flash-attn on \
+  --ctx-size <n> --parallel 1 --cache-type-k f16 --cache-type-v f16 \
+  --jinja --metrics --cache-prompt \
+  --spec-type draft-dflash --spec-draft-model <dflash2.gguf> \
+  --spec-draft-device ROCm1 --spec-draft-n-max 7
+```
+
+- `--fit off` + explicit `--ctx-size`: auto-fit must not resize a context set
+  on purpose. **`--parallel N` DIVIDES `--ctx-size`** — one slot at large ctx
+  is the concurrency policy, concurrent agent loops queue.
+- Pin the drafter to the card holding the target's LAST layers
+  (`--spec-draft-device`); under tensor mode an unpinned draft joins the
+  meta-device KV allocation and aborts the KV build. `--spec-draft-n-max` must
+  be ≤ the drafter's `block_size - 1` (DFlash2: 8 ⇒ 7).
+- Qwen3.8-family templates RAISE on `reasoning_effort=high` (500) — probe
+  low/medium/high/xhigh and map harness levels before declaring ready.
+
+## 5. Split balancing: measure, never interpolate
+
+**A `-ts` step is ONE LAYER, and hybrid stacks do not have uniform layers.**
+qwen35 is 16 × (3 Gated DeltaNet + 1 Gated Attention): one step ≈ 0.43 GiB on
+a DeltaNet boundary, ≈ 1.43 GiB on a full-attention one (weights + that
+layer's own f16 KV) — measured on frank-medium. The gap can jump 2.9 GiB in a
+single step; the best integer split can sit 0.2 GiB from balance while its
+neighbours are 1+ GiB off. An affine fit reproduces the deployed point and
+overstates gaps in between (`tests/frank_medium_unit.bats` encodes the fit as
+a gate; treat a NEGATIVE fitted constant as a unit bug).
+
+Knobs that move weight and REQUIRE a re-measure: `--ubatch-size` (compute
+buffers are **~2x heavier on the output/drafter card** — 512→1536 added
+~3.3 GiB there vs ~1.7 GiB elsewhere), a drafter swap (weights + draft KV),
+`--ctx-size`/`--parallel` (KV). Total free VRAM is invariant across splits —
+only the distribution moves; use that to sanity-check a suspicious row.
+
+**Procedure (one split per load):**
+
+```bash
+WORK=/tmp/split.env; cp scripts/serve-<svc>.env $WORK
+export FRANK_MEDIUM_ENV_FILE=$WORK
+for ts in 39,26 38,27 37,28 36,29 35,30; do
+  sed -i "s|^TENSOR_SPLIT=.*|TENSOR_SPLIT=$ts|" $WORK
+  nohup bash scripts/serve-<svc>.sh >/tmp/split.log 2>&1 &
+  # poll /health (or process exit), then:
+  rocm-smi --showmeminfo vram | grep 'VRAM Total Used'   # sample ~6 s after health
+  pkill -x llama-server; sleep 6
+done
+```
+
+Load → sample → kill, NO requests sent (allocation only). Run under `nohup`
+and poll from a separate call (a load is 30–90 s). Pick the smallest
+inter-card gap that clears the per-card floor with room to spare; one `-ts`
+step ≈ 1.5 GiB at ~6k batch / 262k ctx on 30 GiB cards — enough to bracket,
+not to solve. Prefer balance: the busy card's headroom bounds the context
+(`ctx_extra ≈ (floor − measured_free) / per-position cost on the busier
+card`). A faulted split (`SDMA0 UTCL2 page fault` → `illegal memory access` →
+`ggml_abort`) is OFF-LIMITS — re-measure, never re-tune; more headroom does
+not prevent a boundary-copy fault.
+
+## 6. Drafter KV: sized from the TARGET, bounded by its window policy
+
+`common/speculative.cpp` builds the draft context with
+`cparams.n_ctx = llama_n_ctx(ctx_tgt)` — **no flag caps it.** So:
+
+```
+draft KV = ctx_tgt × block_count × 2 (K,V) × kv_heads × key_length × dtype
+```
+
+…unless the drafter declares a sliding window. Measured at 262,144 target
+ctx: DFlash2 (`sliding_window = 2048`) ≈ 40 MiB; a same-shape 5-layer drafter
+with NO window = 20 KiB/position = **5.0 GiB** — a four-layer swing in the
+balance point, and swapping them invalidated an already-balanced split.
+
+**Failure signature:** the engine loads the whole model, answers `/health`,
+and dies on the FIRST draft decode with `ROCm error: out of memory` /
+`cudaMalloc failed` inside `common_speculative_impl_draft_dflash::process` —
+a sizing failure, not a broken drafter; under a self-healing unit it presents
+as a crash-loop. Read `sliding_window`, `block_count`, `head_count_kv`,
+`key_length` from the drafter's GGUF header first. A compact reader (the
+three format traps: no KV alignment — v3 alignment applies only to the tensor
+section; arrays are `type(9) → element_type(u32) → count(u64)`, element type
+FIRST; the enum is `7=BOOL 9=ARRAY`, 64-bit = 10/11/12, and 8=STRING/9=ARRAY
+is the v2/v3 file order, NOT gguf.h's 2/3):
+
+```python
+import struct, sys
+def rd(path):
+    f = open(path, 'rb'); assert f.read(4) == b'GGUF'
+    struct.unpack('<I', f.read(4)); struct.unpack('<Q', f.read(8))
+    nk = struct.unpack('<Q', f.read(8))[0]
+    def s():
+        n = struct.unpack('<Q', f.read(8))[0]; return f.read(n).decode('utf-8', 'replace')
+    SCALAR = {0:1,1:1,2:2,3:2,4:4,5:4,6:4,7:1,10:8,11:8,12:8}
+    FMT = {0:'<B',1:'<b',2:'<H',3:'<h',4:'<I',5:'<i',6:'<f',7:'<?',10:'<Q',11:'<q',12:'<d'}
+    keys = {}
+    for _ in range(nk):
+        k = s(); t = struct.unpack('<I', f.read(4))[0]
+        if t == 8: keys[k] = s()
+        elif t in SCALAR: keys[k] = struct.unpack(FMT[t], f.read(SCALAR[t]))[0]
+        else:
+            et = struct.unpack('<I', f.read(4))[0]; n = struct.unpack('<Q', f.read(8))[0]
+            if et == 8: keys[k] = [s() for _ in range(n)]
+            elif et in SCALAR: keys[k] = ('arr', et, n); f.read(n * SCALAR[et])
+            else: raise Exception('unsupported arr elem type %d' % et)
+    return keys
+```
+
+## 7. Heterogeneous placement triage (go/no-go with arithmetic)
+
+- **Link:** `LnkCap` vs `LnkSta` at every hop; expect **idle-downshift** (a
+  Gen4 x4 dock idles at Gen1 x4, ~1 GB/s) — measure under load. Per-hop cost
+  vs hidden state (5120-dim f16 = 10 KiB/hop ≈ 1.3 µs at Gen4 x4): bytes are
+  almost never the constraint; **hop count is** — every boundary is a host
+  sync, and a per-op-split runtime can hit 100 splits/token at ~5 % SM. Read
+  `graph splits` from the loader log.
+- **KV is usually the bottleneck:** `KV/token = kv_bytes_per_position ×
+  context` (attention reads the whole cache every token). Highest-leverage
+  placement: **KV on the fastest-memory device together with its attention
+  compute** — never KV alone over the link (GBs over 7.88 GB/s = hundreds of
+  ms/token). Check fit: `kv_positions × slots × bytes + attention_trunk ≤
+  VRAM`.
+- **What placement never buys:** prefill is compute-bound and expert weights
+  are read once per batch — moving them buys nothing and adds a serial stage.
+  Calibration: Strix Halo + 3090, moving 12.5 % of expert mass to the GPU
+  gave decode +12 % but prefill 192 → 32 tok/s. The harmonic
+  `1/(f_big/BW_slow + f_fast/BW_fast)` reproduces the decode gain within ~2
+  points (assumes sequential stages — true at batch 1).
+- **UMA check before assuming additivity:** `mem_info_vram_total` (BIOS
+  carve-out) vs `mem_info_gtt_total` (aperture onto SYSTEM RAM). A big GTT
+  window means the "GPU memory" IS the same LPDDR: adding a stage there adds
+  a compute engine, not capacity/bandwidth. Only discrete VRAM is additive.
+- **Speculation as the "cheap" split:** bandwidth-free (token ids per round)
+  but needs the exact tokenizer for a plain drafter or a head trained for
+  that target; a plain drafter costs K sequential forwards (break-even needs
+  p ≈ 0.7+ at r≈0.4–0.5, K=3); compare against the INCUMBENT (a target
+  already committing ~1.7 tok/round on its own MTP head is a high bar); and
+  check the runtime accepts external drafters at all (closed engines 400
+  unknown drafter names by design). Details: [[DFlash DSpark Speculative Decoding]].
+- **Hazards:** keep paged/sidecar tables where they are read from; keep mmap
+  ON for huge-embedding models (anonymous memory → cgroup kill); CUDA graph
+  capture can abort on unusual graph shapes; make the FIRST measurement a
+  single-device baseline of the runtime on the new device — a split's
+  arithmetic is worthless if the baseline loses to the incumbent; a split
+  consumes the fast device entirely — check what it was serving.
+
+**Verdict ranking:** (1) two independent endpoints — often the real answer;
+(2) one process, weights-resident, KV co-located with attention on the fast
+pool; (3) hot-expert cache only if `misses × bytes × tok/s` fits the link and
+overlaps — no mainstream runtime implements it; (4) name what does NOT help:
+TP across unequal devices, KV on the far device, loading over the link,
+prefill-motivated placements.
+
+## 8. Harness syntax and verification
+
+`llama-bench` separates a LIST with `/` and SWEEP values with `,`:
+`-dev CUDA0,Vulkan1` is TWO single-device runs, never one two-device run;
+`-ts 0.85,0.15` is two sweep values each becoming `[0.85, 0, …]` — device 0
+takes everything. Write `-dev A/B -ts x/y`. Read the table's own `dev` column;
+any placement-dependent number needs an independent memory check
+(`nvidia-smi` sampling while loaded). (This artifact produced a wrong fleet
+conclusion 2026-09-16 — "CUDA + Vulkan cannot serve one model" — with two
+bogus OOMs that were really all-111-GiB-on-the-24-GiB-card.)
+
+Verification battery: `/health`; both cards' memory ≈ half the weights each
+(busier card also carries the drafter; compare `model_bytes/2 + drafter +
+ctx×KV/2 + buffers`); raise ctx by N and watch BOTH cards rise by
+N·bytes/2 — neither card's total may equal the model file (that arithmetic
+rules out replication); `spec_decode_num_drafts_total` > 0 and a real
+completion; a deep prompt (140k) proves a raised window is REAL, not
+declared; repeat prompt → `timings.prompt_n` collapses (prefix cache live);
+`/slots` shows expected `(id, n_ctx)` pairs; two concurrent requests with
+`journalctl -o cat | grep 'slot print_timing'` proves drafting on BOTH slots
+(default journal output truncates these lines).
+
+Ops traps: a server started over ssh outlives stopping the runner (keeps the
+port — `pkill -x <binary>` first); `systemctl start` of a root unit needs
+sudo (polkit "Access denied" otherwise); old crash `ROCm error` lines live in
+the journal forever — check `ActiveEnterTimestamp`/`NRestarts` before
+treating a grep count as a live fault.

+# Llama Cpp Serving Sizing
+
+## 1. Slot-pool sizing against a headroom band
+
+Goal: choose `CTX_SIZE`/`PARALLEL`/KV types so N conversations fit a GPU while
+keeping a requested amount of VRAM free — from measurement, never arithmetic
+guesswork.
+
+1. **Fix the invariants.** Read the payload's KV geometry (attention layers
+   only, KV heads, head_dim, KV dtype bytes) and the per-slot rule
+   `n_ctx_slot = CTX_SIZE / PARALLEL`. A hybrid model with
+   `kv_unified = 'false'` gives each slot its own cache AND a fixed per-slot
+   state buffer — slot count is a memory term, not free.
+2. **Two boots on the real card** (production stopped, per the bench law),
+   each near the target; record `nvidia-smi` used/total plus the boot log's
+   `n_slots`/`n_ctx_slot`: shape A = current/cheap, shape B = new demand.
+   `non-KV = used − (tokens × KiB/token)`; the two rows separate
+   weights/buffers/graphs from the new demand (a 918 MB projector bills
+   ~1.4 GiB).
+3. **Solve the band:** `KV_tokens ≤ (card − non-KV − headroom_low) /
+   KiB/token`, round the pool DOWN to a multiple of `PARALLEL × 4096` so every
+   slot gets an equal integer window. Boot and measure; if outside the band,
+   walk one step — never re-derive from a formula.
+4. **Propagate the per-slot number — it is the client contract:**
+   `models.yml` `contextWindow` = `n_ctx_slot` (NOT the model's native window),
+   or long conversations die with `400 exceed_context_size_error` instead of
+   compacting; compaction/summary budgets sized to the old window get
+   re-checked; endpoint docs and the rollback table move too.
+5. **Prove behaviour:** boot-log slot count, `nvidia-smi` free in band, N
+   concurrent requests answered in parallel with N+1 queued, and — if a
+   projector ships — a solid-color image probe through an **`image_url`
+   content part** expecting the exact color. The legacy top-level `images`
+   field is silently ignored, so a probe that uses it measures a
+   hallucination, not vision.
+
+Gotchas: shorter slots can make decode FASTER (~5 % measured); the KV pool is
+allocated whole at boot so post-boot `memory.used` IS the ceiling; record both
+measured rows in the service `.env` comment block and mirror the non-KV price
+in the bats budget gate so a shape that busts the band fails the suite instead
+of the boot.
+
+## 2. Per-device VRAM accounting ("where did the memory go?")
+
+First decide which kind of memory is in question:
+
+| device | kind | read it with |
+|---|---|---|
+| RTX 3090 (Dankclaw) | discrete GDDR6X | `nvidia-smi --query-gpu=memory.total,memory.used,memory.free` |
+| gfx1151 iGPU (Dankclaw) | **UMA** — "VRAM" is host RAM | `/sys/class/drm/card1/device/mem_info_gtt_{total,used}` (114 GiB) vs `mem_info_vram_*` (2 GiB carve-out) |
+| R9700s (Dankserver) | discrete | `rocm-smi` figure (64 GiB, SVM-backed) |
+
+Per-process truth on NVIDIA:
+`nvidia-smi --query-compute-apps=pid,process_name,used_memory`. Never add the
+iGPU's GTT to host RAM as a separate pool; `free -g` is the arbiter for
+co-tenants.
+
+- **Engine ledger first.** Halogen prints weights pinned (+ remaining 2 MiB
+  contiguous blocks — the honest fragmentation signal: 240 blocks/12.3 GiB
+  after reboot vs 475/14.7 GiB before means the model did not come back into
+  the same hole), device budget, KV pool/working split, "left for everything
+  else". llama.cpp prints at `llama-model.cpp:1827` (per-backend model buffer)
+  and `llama-context.cpp:692` (compute buffer) — but **`llama-bench`
+  suppresses loader INFO and a systemd unit did not put them in the journal**
+  (verified `grep -c` = 0). Recipe: one launch through `llama-cli`/`llama-server`
+  keeping the first ~200 lines.
+- **Otherwise compose from tensor sizes.** Group the GGUF tensor table by
+  role (Flash-Next example: 75.0 GiB experts at 1.5625 GiB/layer, 32.8 GiB PLE
+  table, 3.2 GiB everything else), KV ≈ 2 KiB/position per f16 attention
+  layer, × derived context. Vendor delta is real: same layers+KV cost 12.80
+  GiB under Vulkan vs 14.99 GiB under CUDA (~3.3 vs ~1.1 GiB of
+  graph/compute pool).
+- **Traps:** mmap'd PLE is reclaimable page cache; `-ot` makes it pinned —
+  "move layers to the card" converts reclaimable cache into device memory and
+  frees nothing for co-tenants. A served model's footprint ≠ weight size
+  (frank-small: 22.6 of 24.1 GiB for an 11.29 GiB model). Do the capacity
+  subtraction before designing: 12 attn layers × 1.62 GiB + 200k f16 KV =
+  28.6 GiB > 24.1 GiB usable → KV-in-VRAM on that pair only reaches ~64k.
+- **Context lengths: derive, never remember.** `llama-bench` computes
+  `n_ctx = n_prompt + n_gen + n_depth` (defaults 512/128/0, type_k/v F16,
+  flash_attn AUTO, split_mode LAYER). `-p 512,16384 -n 64` = contexts
+  576/16,448; a plain `tg` row has ~zero depth — `-d` is the only thing that
+  puts KV in the picture.
+- **Label every number** measured / derived / inference, and state the context
+  each figure was taken at — 12.8 GiB at 65,568 tokens is not the same claim
+  as at 200k.
+
+## 3. Prompt cache and state sizing
+
+`--cache-ram` (MiB, default 8192) is HOST RAM for saved prompt states —
+unpinned, on demand, moves no VRAM. `--ctx-checkpoints` (default 32) is a
+different mechanism: per-slot KV snapshots; `0` disables them.
+
+**State law** (compute before trusting any cap): a state is the serialized KV
+of the whole sequence + constant recurrent state + the draft context's KV:
+`per_token = 2 × n_full_attn_layers × n_kv_heads × head_dim × bytes (K and V) +
+draft_per_token`. Measured on frank-medium (qwen3.5 hybrid, f16, MTP draft):
+16×4×256×2×2 = 64 KiB/token + 4 KiB draft = **68 KiB/token**; a full
+196,608-token slot state ≈ 12.8 GiB. Cross-check against the journal's
+`prompt state size` lines — the two must agree.
+
+**The journal is the instrument:** `exceeds cache size limit … skipping` =
+cap binding in production; `making room … removing oldest` / `cache size
+limit reached` = eviction, and the printed size proves the active cap. Do NOT
+claim a raise is proven by `prompt_tokens_cached_total` rising — on exact
+repeats that counter is 0 by construction.
+
+**Hybrid + zero-checkpoint trap:** for a hybrid (DeltaNet/SSM + attention)
+model, `seq_pos_min` sits at the END of the slot's own prompt (a recurrent
+cell stores only the last position), so with `--ctx-checkpoints 0` there is no
+checkpoint to fall back on and the server logs `forcing full prompt
+re-processing … (likely due to SWA or hybrid/recurrent memory)`. Consequences:
+intra-slot reuse only survives when the request echoes the assistant's
+previous reply verbatim (a pure user resend is always a full re-prefill even
+at f_sim 1.000); the RAM prompt cache becomes the ONLY carrier of a
+conversation state ACROSS slots, so a cap that refuses deep states costs
+minutes of re-prefill whenever slots are reassigned; state restoration only
+runs via the LRU path (or LCP with f_keep < 0.5) — a plain prefix hit never
+calls `prompt_load`.
+
+**Verify a change:** live argv carries the flag (not the deploy log); `/health`
+200 + real completion; VRAM unchanged and host RAM mostly free; no new
+`exceeds cache size limit` lines, with a `making room` entry larger than the
+old cap as direct proof. If the ceiling itself was not exercised live, say so —
+crossing it needs a >120k-token conversation and must not run beside a live
+service (bench law).
+
+## 4. QSA flash-attn assert fix (qwen4exp)
+
+`--flash-attn on` aborts graph build for qwen4exp models:
+`GGML_ASSERT(a->type == GGML_TYPE_F32)` at `ggml.c:5371` through
+`build_attn_qsa`. Root cause: `build_attn_qsa` calls `ggml_fill` on the
+F16-cast kq mask returned by `get_kq_mask()` when flash attn is on, but
+`ggml_fill` requires F32.
+
+Fix (mirrors the MLA sparse path in `llm_graph_context::build_attn`): run the
+top-k mask surgery on the F32 base mask (`inp->self_kq_mask`), cast to F16
+only at the attention call when `flash_attn` is enabled
+(`kq_mask_attn = cparams.flash_attn ? ggml_cast(ctx0, kq_mask_top_k,
+GGML_TYPE_F16) : kq_mask_top_k`). The patch lives at
+`scripts/patches/qwen4exp-qsa-f32-mask.patch`.
+
+Only the charlie12345/ROCmFPX build-qwen38 (PR #27742 qwen4exp merged) takes
+it; CIRU, upstream and stock builds do not. Validate live: load with
+`--flash-attn on`, health 200, a real completion finishing `"stop"`, journal
+clean of `GGML_ASSERT`/`cudaMalloc`/`missing tensor`, and flash-attn engaged
+in the timings. Context cap for full-model residency on that shape stayed
+32,768.

+# PCIe Link and Atomics
+
+## 1. Degraded or just idle?
+
+The trap: an idle GPU reports `LnkSta: Speed 2.5GT/s (downgraded)` — the
+driver downshifts to Gen1 for power. That is not a fault and not the slot's
+fault. Never conclude from an idle reading.
+
+1. **Path ceiling from the kernel (cheapest, most decisive):**
+   `sudo journalctl -k -b --no-pager | grep "available PCIe bandwidth"` →
+   `pci 0000:c4:00.0: 63.012 Gb/s available PCIe bandwidth, limited by 16.0
+   GT/s PCIe x4 link at 0000:00:03.1 (capable of 252.048 Gb/s with ... x16)`.
+   The "limited by" device names the **bottleneck** (usually a root port) and
+   its width — that is the number a swap could move; "capable of x16" is the
+   endpoint's OWN capability, and the gap between them is the story.
+   `dmesg` rotates; `journalctl -k -b` keeps this boot.
+2. **Both sides separately:** `LnkCap`/`LnkSta`/`LnkCtl2` on endpoint AND root
+   port. `LnkCtl2: Target Link Speed: 16GT/s` on both ends = the platform
+   intends Gen4, so a Gen1 current speed is power management, not
+   misconfiguration. A root port whose `LnkCap` width exceeds the trained
+   width means the socket/adapter wires fewer lanes — **M.2 connectors are 4
+   lanes by pinout; an M.2 riser can never deliver more.**
+3. **Prove the link under load (the step people skip):** on NVIDIA sample NVML
+   while the GPU works
+   (`nvidia-smi --query-gpu=pcie.link.gen.current,pcie.link.gen.hostmax,pcie.link.width.current,pcie.link.width.max`):
+   `gen.current` climbing 1 → `hostmax` = idle downshift, healthy; stuck below
+   `hostmax` under load = real degradation; `width.current < width.max` under
+   load = **physical lane limit** — no software touches it. On a busy
+   production GPU this is a usage smoke test, not a benchmark — never stop a
+   live service to read its link.
+4. **Do not plan hardware from `dmidecode -t slot`** — consumer firmware
+   labels Ethernet/SD controllers as "M.2 slots" and advertises slots in PCI
+   domains that do not exist. Trust `lspci -nn | grep "PCI bridge"` and
+   `lspci -tv` (empty root ports still enumerate; an absent port is absent).
+5. **"Would moving the card help?"** Compare the bottleneck device from step 1
+   with the target port's `LnkCap` width; two M.2 sockets = both x4 = a
+   no-op. Clean `DevSta`/`CESta` with a low trained speed means "wired
+   narrow", not "failing". Report ceiling, card capability, what the idle
+   reading meant, and whether any physical change moves the number.
+
+Gen4 usable payload after 128b/130b: **x4 7.877 GB/s, x8 15.75, x16 31.5**.
+
+## 2. The engine shape decides whether the link matters at all
+
+| engine shape | what crosses PCIe per token | link matters? |
+|---|---|---|
+| streams weights (expert LRU, paging) | the missed weights (~GB/token) | **yes — decisive** |
+| computes offloaded weights in RAM (llama.cpp `-ot exps=CPU`) | activations only (~KB) | no; host RAM bandwidth decides |
+| everything resident | nothing | no |
+
+**Ceiling arithmetic:** `link time/token = active expert bytes / measured
+H2D rate`; `ceiling = 1 / link_time × resident-fraction saved (LRU hits)`.
+Compare against the compute-in-RAM path at host RAM bandwidth (256 GB/s
+LPDDR5X on the Strix Halo). **If the link is >10x slower than the memory
+behind it (x4 is 31x here), streaming loses by construction and no tuning
+rescues it; doubling the link only doubles a losing number.**
+
+Worked example (Dankclaw 2026-09-16): Gen4 x4 measured H2D **6.72 / D2H 6.60
+GB/s** (85 % of spec) — pinned H2D ≈ async, pageable within 1 %, i.e.
+link-limited not staging-limited. A 3 MiB slab (the expert-streaming
+granularity) = 474 µs. A3B MoE at Q4_K_M (~1.70 GiB active/token) → 272
+ms/token ⇒ **3.7 tok/s** (4.6 with 20 % resident) vs measured **20.46 tok/s**
+with experts computed on the CPU, 25–26.5 on the iGPU. The streaming design
+loses 3–5x.
+
+## 3. Measure the link: two probes, same mechanics
+
+Stop **all** production services first (fleet bench law) — the 3090's VRAM
+may be nearly full, and the probe contends for the very link it measures.
+
+**CUDA probe** (`pcie-link-test.cu`): sweep {3, 16, 64, 256 MiB, 1, 2 GiB}
+with `cudaMalloc` + `cudaHostAlloc`, event-timed; per size measure sync H2D,
+async H2D, D2H, one single transfer, and pageable H2D. `3 MiB` is the row
+that matters for expert streaming; big sizes give the ceiling.
+
+**HIP probe for RDNA4** (`pcie_bw.hip`) — the ROCm landmines each cost real
+time, so encode them:
+
+- `hipGetDeviceProperties` SEGFAULTS on some builds; use `hipGetDeviceCount`
+  + `hipSetDevice` only. First line: `setvbuf(stdout, NULL, _IONBF, 0);` — a
+  segfaulting process loses block-buffered stdout and hides the crash point.
+- Build with an explicit arch: `HIP_TARGETS=gfx1201 hipcc -O2
+  --offload-arch=gfx1201 -o p p.hip`; compile with `| grep -E "error:"`,
+  never `| tail -N` (truncation hid a missing `#include <cstring>`).
+- `hipMemset`/`hipDeviceSynchronize` are `[nodiscard]` — use or cast.
+- Mount the whole `/dev/dri` into ROCm containers; individual `renderD*`
+  nodes enumerate but fail context creation.
+- `rocm-smi --showmetrics`: `pcie_link_width` is trustworthy, but
+  `pcie_link_speed` reads the ASPM idle value and `pcie_bandwidth_acc/inst`
+  are usually `N/A` on consumer cards — live traffic generally cannot be
+  sampled.
+
+```cuda

+#include <cstring>
+#include <cstdlib>
+#include <hip/hip_runtime.h>
+static double one(size_t bytes, bool pinned, int iters) {

+    size_t sz[] = {2459136UL, 3UL<<20, 16UL<<20, 64UL<<20, 256UL<<20, 1UL<<30};
+    for (int i = 0; i < 6; i++) {
+        size_t b = sz[i];
+        int iters = (b >= (1UL<<30)) ? 10 : (b >= (256UL<<20)) ? 20 : 100;
+        printf("  %10.3f MiB | pinned %6.2f | pageable %6.2f\n",
+               b/1048576.0, one(b,true,iters), one(b,false,iters));
+    }
+    return 0;
+}
+```
+
+**Reading it:**
+
+- **Engine-vs-link is the diagnosis, not the raw number:** compare
+  `engine_effective_GB_s` to `link_GB_s` at the SAME transfer size. Engine at
+  ~40 % of the link at the same granularity = the wire is not the problem and
+  no hardware change will help.
+- Achieved GB/s is itself the proof of the trained link state (6.7 GB/s only
+  exists at Gen4 x4) — no separate under-load `LnkSta` sample needed.
+- **pinned ≈ pageable ⇒ pinning is not a lever.** async ≈ sync ⇒ link-limited
+  (the usual "pageable costs 2x" rule does not apply at this link).
+- Small-transfer penalty (2.345 MiB: ~106 µs vs ~78 µs ideal, ~21 %) is
+  per-transfer overhead — recoverable only by BATCHING transfers, not by a
+  faster link. (Dankserver 2026-09-29: bulk 22.7 GB/s at the 2.344 MiB slab =
+  91 % of Gen5 x8, while the engine's effective read path ran ~9.5 GB/s — the
+  gap is the fork's gather software path, not the wire.)
+- Both GPUs symmetric ⇒ no cross-device rebalance is available; measure both.
+- Don't quote a derived line from inside a probe without hand-checking it —
+  a printf format/argument mismatch in one of these printed a nonsense
+  ceiling. GiB→GB before dividing.
+
+## 4. The PCIe-atomics wall (AMD multi-GPU collectives)
+
+**Symptom:** multi-GPU AMD host fails TP/PP; the failure surfaces as
+`hipLaunchKernel: hipErrorIllegalState` for `ncclDevKernel_*` — nothing in
+vLLM/RCCL/PyTorch names atomics. Get the real message:
+
+```bash
+AMD_LOG_LEVEL=3 <the failing process>
+# → "Pcie atomics not enabled, hostcall not supported" → "AQL dispatch failed!"
+```
+
+**Cause chain:** RCCL kernels carry a hidden hostcall-buffer parameter; ROCr
+refuses to fill it without PCIe atomics, which it reads **once at driver
+probe** (`rocclr/device/rocm/rocdevice.cpp` `checkAtomicSupport()` — no else,
+no override). **No env var, module param, or sysfs toggle exists** —
+`setpci -s <gpu> CAP_EXP+28.w=0440` (DCTL2 bit 6) changes nothing at runtime.
+
+**Check the CHAIN, not the card:**
+
+```bash
+sudo lspci -vv -s <gpu> | grep -E "AtomicOpsCtl|LnkSta|LnkCap"  # want ReqEn+
+lspci -tv                                                        # every hop
+sudo lspci -vv -s <bridge> | grep AtomicOpsCap                   # want Routing+
+```
+
+`Routing-` is a read-only hardware capability. Typical AM5 layout: one x16
+slot on CPU root ports (atomics fine), the rest behind the chipset (usually
+not). Bandwidth for TP is small anyway: ~10 MB per token-step for a 27B at
+batch 4 ≈ 1.4 ms at Gen4 x4 — compute-bound, not interconnect-bound.
+
+**Probe matrix (bare 2-rank `torch.distributed`, one process per GPU, 25 s PG
+timeout) — one probe answers several design questions:**
+
+| Op | CPU-lane card | chipset card | Decides |
+|---|---|---|---|
+| `broadcast`/`all_reduce`/`barrier` | OK | FAIL | TP is dead |
+| `send`/`recv` (P2P), in ISOLATION | hang | FAIL | **PP is dead too** — vLLM's PP handoff IS this primitive |
+
+Test `send`/`recv` alone (a prior failed op leaves the group broken). Run the
+probe from a REAL file (`torch.multiprocessing.spawn` re-executes it; piping
+into `python3 -` fails with `FileNotFoundError: '/<stdin>'`). `world_size=1`
+always succeeds — **one-card success proves nothing.**
+
+**SAFETY — non-negotiable:** never run a GPU experiment beside a serving
+unit: `sudo systemctl stop <svc> && sudo systemctl mask <svc>` first (mask,
+never disable — disable deletes a relinked unit file), or use a host that
+serves nobody. A hung AQL dispatch can wedge the GPU driver; a probe beside a
+live service on 2026-09-16 preceded a hard host down (no ARP, no ICMP from
+two subnets, power cycle required). Telling off from wedged afterwards: `ip
+neigh show <ip>` from a peer — `FAILED`/`INCOMPLETE` = off/NIC dead; a wedged
+kernel usually still answers ARP. Validate your own probe's naming before
+reporting an outage (`gitea` vs `gitea-server`).
+
+**Fixes, ranked:**
+
+1. CPU-attached M.2 → PCIe x4 riser (~$30) — puts the card on the CPU root
+   complex; x4 suffices for TP.
+2. Board whose CPU x16 bifurcates x8/x8 (done 2026-09-20 on dankserver — both
+   R9700s on root ports `00:01.1`/`00:01.3`, every bridge `Routing+`, both
+   endpoints `ReqEn+`).
+3. llama.cpp `--split-mode layer` — no collectives at all ([[Llama Cpp Multi-Device Splits]]); costs the GGUF conversion plus paged attention /
+   continuous batching / spec decode.
+4. Independent TP=1 replicas + routing proxy — cards never share one model.
+
+**Closed software routes (do not re-litigate):** vLLM's IPC custom allreduce
+is gated by a CUDA-sm-keyed table (`{9.0, 10.0, 10.3, 10.7}`; ROCm reports
+12.0 → off on RDNA4 by code limit) — and patching it is insufficient because
+TP init's `broadcast`/`barrier`/logits `all_gather` have no non-RCCL path. A
+fork wrapping `.all_reduce` (e.g. radiance `RADIANCE_USE_R4D_AR` one-shot
+P2P, gloo for IPC-handle exchange) does not intercept
+`PyNcclCommunicator.__init__`'s warmup allreduce. NCCL symmetric memory needs
+`ncclDevComm*` (many builds ship the version string without the device API).
+P/D disaggregation needs a KV connector AND coordination collectives. gloo is
+CPU/TCP — unreachable for per-layer TP.
+
+**Open, unverified:** rebuilding RCCL so kernels stop declaring a hostcall
+buffer (`-mprintf-kind=buffered` is the usual claim) — counter-evidence: no
+live `printf`/`assert` in RCCL device source. Test path: rebuild, dump a
+kernel's declared args (`roc-obj-extract` + `llvm-readelf --notes`), look for
+`hidden_hostcall_buffer`; if gone, retry the 2-rank probe (service stopped).

+# RDNA4 Container Serving
+
+Bring-up path for Dankserver (2x Radeon AI PRO R9700, gfx1201, 31.86 GiB each =
+**63.7 GiB real VRAM**, 246 GiB RAM, 7700X) with
+`docker.io/tcclaviger/vllm` (vLLM 0.29.0.dev, GLM/Qwen-specialised RDNA4 build
+with native MoE quant kernels and a first-class expert offload planner). The
+tuning history and current deployed shape live in
+[[dankserver-qwen38-fp8-expert-offload-tuning]]; this page is the bring-up law.
+
+## 0. Know the box — and its phantom third GPU
+
+`torch.cuda.device_count()` returns **3**; summing `total_memory` overstates
+the box as 186.7 GiB. The third device is the 7700X's integrated Vega
+(gfx1036): torch reports ~123 GiB for it, `rocm-smi` reports 0.50 GiB,
+allocating on it moves system `MemAvailable` 1:1 (it is GTT over DDR5, not
+dedicated VRAM), and it dies with `hipErrorInvalidKernelFile` when the image
+ships no code for that arch. **Never sum device `total_memory`; never count
+the iGPU as headroom or a workload.**
+
+## 1. Preflight: is the quant class EXECUTABLE, not merely present?
+
+Expert offload is mandatory when weights exceed VRAM, and it requires the
+checkpoint's experts class to have BOTH a compiled kernel AND an
+`offload_recipe` ("a pinned expert has no host copy, so there is no
+read-through fallback" — startup aborts otherwise). Check BEFORE downloading
+anything:
+
+```bash
+podman run --rm --device /dev/kfd --device /dev/dri --device /dev/mem \
+  -e HIP_VISIBLE_DEVICES=0,1 --entrypoint bash $IMAGE -c '
+  nm -D /app/r4dhip/r4d.so | grep -oE "gemm_moe_[a-z0-9_]+" | sort -u
+  grep -rl offload_recipe /opt/vllm/lib/python*/site-packages/vllm/model_executor/layers/fused_moe/'
+```
+
+| quant | kernel in `r4d.so` | experts class | verdict |
+|---|---|---|---|
+| FP8 | yes | `Fp8HipMoEExperts` | **serves** |
+| MXFP4 / DSFP4 | yes (`gemm_moe_mxfp4a8_*` / `dsfp4a8_*`) | `R4dMxfp4MoEExperts` / `R4dDsfp4MoEExperts` | **serves** |
+| W4A16 | **no** `gemm_moe_w4a16_*` | `R4dW4a16MoEExperts` exists | silently falls back to generic `TritonWNA16Experts`, no recipe → startup halts |
+| RFA | none | no class at all | out |
+
+Also confirm the architecture routes natively with NO overlay
+(`ModelRegistry.get_supported_archs()` for `Qwen4Exp`/`Glm5`). The stock image
+natively carries Qwen3.8/Qwen4Exp and GLM-5.x including MTP heads. **Do not
+apply vendor overlays** against a fast-moving pre-release image — the breakage
+misleads (a missing symbol in the overlay's OWN copy of a module masks the
+real cause, then moves to another symbol each patch;
+`cannot import name 'checkpoint_has_lm_head'` = overlay clobbered
+`transformers_utils/config.py`). The image ships quantizers for
+`rfa|rfi|mxfp4|mxfp4ocp|paro5` under `/app/tools/quantize.py`
+(`--fp8-attn --quant-only --dry-run` first) if a re-quant is needed — note it
+can run MXFP4/DSFP4/FP8 but only PRODUCE rfa/rfi/mxfp4/paro.
+
+## 2. Fetch with verification, always
+
+Gated repos: token never in argv (`pgrep -a curl` prints command lines).
+Build a mode-600 curl config once:
+
+```bash
+{ printf 'header = "Authorization: Bearer '; cat ~/.cache/huggingface/token; printf '"\n'; } \
+  > ~/.cache/huggingface/curl.conf && chmod 600 ~/.cache/huggingface/curl.conf
+curl -K ~/.cache/huggingface/curl.conf -f -sS -L -C - -o "$out" "$url"
+```
+
+`--fail` is MANDATORY — `curl -o FILE URL` exits 0 on HTTP 401/403 and writes
+the error body as a "successful artifact" (a gated repo once yielded three
+153-byte shards with identical sha256s and a cheerful DONE banner). `-C -`
+resumes torn shards; HTTP/2 cancels leave silently truncated files, so
+re-verify EVERY shard's byte count against the Hub manifest (and the LFS
+sha256) before serving. The AGENTS.md Secret Rules carry the token-hygiene
+law; [[frank-medium-model-swap]] has the same detail for GGUFs and
+`.partNofM` fragments.
+
+## 3. Serve — the known-good invocation and its traps
+
+```bash
+sudo sh -c 'sync; echo 3 > /proc/sys/vm/drop_caches'
+podman run -d --name <ctr> --ipc=host --ulimit memlock=-1:-1 \
+  --cap-add SYS_PTRACE \
+  --device /dev/kfd --device /dev/dri --device /dev/mem \
+  -e HIP_VISIBLE_DEVICES=0,1 -e VLLM_ROCM_USE_AITER=0 \
+  -v /home/dank/models/<model>:/models:ro \
+  $IMAGE /models --served-model-name <name> --port 7770 \
+  --tensor-parallel-size 2 --max-model-len 65536 \
+  --kv-cache-memory-bytes 2147483648 \
+  --max-num-seqs 4 --gpu-memory-utilization 0.95 \
+  --enable-prefix-caching --trust-remote-code
+```
+
+- **Entrypoint already execs `vllm serve "$@"`** — pass the model path as the
+  first argument and do NOT pass `serve` (podman then tries to pull `serve`
+  as an image name). `-e VAR=1` must come BEFORE the image name.
+- **Mount the whole `/dev/dri`, never individual render nodes** (§4).
+- `--ipc=host` and `--shm-size` are mutually exclusive in podman.
+- `podman run -d` without `-a` sends container stdout nowhere — read
+  `podman logs <ctr>`; and vLLM writes `Application startup complete` to
+  **stderr**, so a `podman logs X 2>/dev/null | grep -q` readiness gate never
+  fires.
+- Start at 65536, not the native ceiling; prove the plan, then scale.
+- Load takes ~5 min with `/health` refusing the whole time — do not kill the
+  process (deploy.sh waits 20 min).
+
+## 4. Container GPU-init triage (ordered)
+
+1. **Enumerate-vs-context trap (most common):** individual
+   `renderD*` nodes give HIP the render nodes WITHOUT the primary `card*`
+   nodes — it enumerates agents (`device_count()` returns N) and then refuses
+   every context: `RuntimeError: No CUDA GPUs are available` on the first
+   real op. A/B-confirmed 2026-09-19. Rule: `--device /dev/kfd --device
+   /dev/dri --device /dev/mem`; restrict GPUs with `HIP_VISIBLE_DEVICES`,
+   never with device nodes.
+2. **`device_count()` is not evidence.** Prove usability with a real op
+   (`(a@a).sum().item()` on a fresh `torch.randn`), then repeat via
+   `mp.spawn`, `mp.fork`, and `subprocess.run([sys.executable, ...])`, and
+   cross-check `rocm-smi --showmeminfo vram`.
+3. **memlock rlimit → a MISLEADING CUDA OOM.** Host default 8192 KB; a pin
+   larger than the limit fails as
+   `torch.AcceleratorError: CUDA error: out of memory` raised from
+   `pin_memory()` — it names the accelerator but the fault is host pinned
+   memory. It cannot be raised from inside a container or even from root's
+   own shell (`Operation not permitted`); only PAM applies it at login, so
+   fixes only affect NEW sessions:
+   `/etc/security/limits.d/99-memlock.conf` with
+   `* - memlock unlimited` + `root - memlock unlimited`; the container needs
+   `--ulimit memlock=-1:-1` to inherit. Discriminating test after the fix:
+   the container reports `unlimited` AND small pins succeed; if pins still
+   fail, memlock was never the cause.
+4. **`/proc/meminfo` TAB trap:** the key/value separator is a TAB, so
+   `grep MemAvailable /proc/meminfo | tr -s " " | cut -d" " -f2` returns
+   EMPTY and a following awk prints `0.0` — a false "host out of memory" on a
+   host with hundreds of GiB free, which invites aborting something healthy.
+   Tab-safe: `awk -v k='MemAvailable:' '$1==k {printf "%.1f", $2/1048576;
+   exit}' /proc/meminfo`, cross-check `<= MemTotal`, refuse to print a zero.
+   Use `scripts/dankstatus.sh` instead of hand-rolling.
+5. **Silent-parse traps:** `grep -c PATTERN file || echo 0` yields TWO lines
+   (grep prints 0 AND exits 1) — `[: 0\n0: integer expected`; use
+   `| head -1` or `|| true`. `systemctl is-enabled` can emit multiple lines.
+   `rocm-smi --showmeminfo vram --csv` column order is `device, VRAM Total
+   Memory (B), VRAM Total Used Memory (B)` — reading $3 as total/$4 as used
+   yields 0.00; filter to `^card[0-9]+$`.
+6. **Guard the box:** long loads with co-tenants can drive RAM to 0 — abort
+   before the OOM killer (`MemAvailable < 4 GiB → podman rm -f`, exit 1).
+7. **Drop page cache before a large load** (`echo 3 > /proc/sys/vm/drop_caches`)
+   and confirm the drop was actually in effect for the run before treating a
+   failure as a capacity wall — a stale "it doesn't fit" from a contaminated
+   run is expensive to unwind.
+
+## 5. Memory budgeting: the levers are not where they look
+
+The planner builds `budget = total × util`, subtracts a KV reserve, and gives
+the REMAINDER to the expert arena. Consequences, all measured:
+
+- **`--gpu-memory-utilization` grows the ARENA, not the KV pool** (KV stayed
+  0.64 GiB at util 0.95 and 0.98). The arena is the only elastic term.
+- **Lowering `--max-model-len` is the WRONG lever and backfires:** a smaller
+  context shrinks the reserve, handing the space to the arena — measured 65536
+  → 0.64 GiB KV, 32768 → 0.34 GiB KV.
+- **Hybrid-attention undercount:** the planner's per-token KV figure (9190
+  B/token for Qwen4Exp) misses the large fixed per-sequence Mamba state
+  (~2x), so the reserve is always short and the arena silently covers it.
+  Fix by pinning the pool: `--kv-cache-memory-bytes <BYTES>` (2 GiB →
+  113,595 tokens / 3.47x concurrency at 32k). For long context,
+  `--kv-offloading-size` (GiB) spills KV to host.
+- **`--expert-offload-mem` caps the HOST side, not the VRAM arena**
+  (`cap = int(x * GIB)` against `host_memory_available()`). Do not reach for
+  it to fix a VRAM problem; to grow the arena, shrink the KV pin or raise
+  util (see [[dankserver-qwen38-fp8-expert-offload-tuning]] for the
+  util=1.0 unbootability law).
+
+**Read the plan — it is the real acceptance test:**
+
+```
+expert offload: AUTO-ENABLED, weights 62.54 GiB per rank exceed the 30.27 GiB budget (TP2)
+  budget (total x util)      30.27 GiB
+  non-expert weights          6.28 GiB
+  KV reserve                  0.36 GiB   <- sanity-check against the model's own per-token figure
+  CUDA graphs                 0.66 GiB
+  runtime overhead            7.60 GiB
+  expert cache space         15.36 GiB   6712 slots of 2.344 MiB
+  host-backed experts/rank   52.74 GiB   23040 experts
+  host: 105.48 GiB across 2 ranks of 160.89 GiB usable
+```
+
+Host fits when `host_total < usable`. The PLE n-gram table rides memfd and is
+SHARED across TP ranks.
+
+**Loading mechanism** (for reasoning about peak RAM): weights never materialise
+in VRAM — expert Parameters start as CPU staging tensors; each layer's
+`weight_loader` counts shard events and, on layer completion,
+`ExpertTopology.split_layer` moves that layer's experts into the VRAM arena
+and compacts the rest into exact-size pinned host tensors behind UVA. Peak
+host RAM = `host-backed set + layers still loading`, not the whole model. At
+runtime `apply_hot_cold` sends arena-resident experts down a hot GEMM and the
+rest straight over PCIe via UVA views — no staging copy in the critical path.
+
+**Emulation check:** a dequantize-to-compute path doubles real host RAM (118
+GiB offload request → ~238 GiB) and is invisible in the weight count. Read the
+log for `Using 'EMULATION' Mxfp4 MoE backend` before concluding "doesn't fit".
+
+## 6. Performance profile and honest measurement
+
+Decode on this pair is **PCIe-gather-bound, context-independent**: 12.11
+tok/s FLAT from 304 to 16,095 context tokens — KV attention is not the cost.
+With ~29 % of experts arena-resident, ~0.84 GB crosses PCIe per token at the
+engine's effective read rate; cold-vs-warm differing ~10 % confirms the LRU
+works; growth is linear in hit rate, and only speculative decode cuts
+sequential STEPS rather than making each cheaper.
+
+**Benchmark traps that produced fake numbers here:**
+
+- `max_tokens=1` is not TTFT (the server can satisfy it without doing the
+  work — prefill looked flat at 1.26 s for 16k AND 30k prompts). A 64-token
+  non-streamed reply is time-to-64-tokens (decode-bound, flat ~9.6 s at every
+  length). Correct TTFT: stream and time the FIRST content-bearing chunk.
+- A small repeating word loop is prefix-cacheable AND n-gram-predictable — a
+  43-word cycle reported 22,897 tok/s prefill, almost entirely cache hit. Use
+  a large vocabulary in shuffled order and print `cached_tokens`.
+- ~1.2 s fixed per-request overhead swamps prefill below ~16k tokens; compare
+  prefill at 30k+ only.
+- Size prompts with `/v1/messages/count_tokens` (a chat call for counting
+  pollutes the metric); guessing words-per-token silently overran the window
+  (HTTP 400).
+- Always run a canary: plant a unique token at the END of a long prompt and
+  ask the model to quote it — proves prompts reach the model at all.
+- Measure warm AND long (`podman exec` + urllib at 127.0.0.1:7770): a 33-token
+  reply read 14.6 cold / 20.3 warm; a 768-token generation hit 25.7; two
+  concurrent streams scaled to 47 aggregate.
+
+**Levers (all opt-in):** `--expert-prefetch N` takes an INT depth, not a
+boolean (default 0; at depth 1 only ~10 % cold-vs-warm difference — the cache
+already works); `CLAV_TUNABLEOP_SWEEP=1` autotunes GEMM shapes (silently
+skipped under expert offload unless `CLAV_TUNABLEOP_WITH_OFFLOAD=1` too —
+see [[dankserver-qwen38-fp8-expert-offload-tuning]] for why it was rejected);
+`--expert-precise-memory` swaps the fitted overhead figure in.

+# RDNA4 MoE Expert Offload VRAM Budget
+
+For VRAM-bound vLLM on the tcclaviger RDNA4 fork (frank-primary: Qwen3.8-
+Flash-Next FP8, TP=2, 2x R9700 at 31.86 GiB each, expert offload to host RAM).
+Tuning history and the deployed shape live in
+[[dankserver-qwen38-fp8-expert-offload-tuning]]; boot-failure capture lives in
+[[vLLM Boot Forensics and Config Interrogation]].
+
+## 1. The plan law
+
+```
+arena = budget − non_expert − kv_reserve − cuda_graphs − runtime_overhead
+budget = device_total × gpu_memory_utilization          # expert_plan.py build_plan
+slots  = arena // expert_bytes                          # 2.344 MiB/slot ⇒ 437 slots/GiB
+```
+
+**The arena is DEVICE-resident, so the plan predicts reality:** the fp8
+3-window shape's plan totalled 28.27 GiB and `rocm-smi` measured exactly
+28.27 GiB. `weights + pinned_pool + graphs + arena + non-torch (≈1.45 + 0.57
+driver reserve)` vs 31.86 GiB predicts a boot failure before it happens.
+
+Which terms a deploy can move:
+
+| term | reachable? | how |
+|---|---|---|
+| budget (util) | **yes, law-capped** | `--gpu-memory-utilization`; +0.01 = +0.32 GiB on 31.86 GiB cards |
+| CUDA graphs | **yes** | container env `VLLM_CUDAGRAPH_MEM_BASE_MB` / `_PER_GRAPH_MB` (or `_ESTIMATE_MB` for an explicit total) |
+| non-expert weights | no | checkpoint census |
+| KV reserve | no | registry constant: 9190 B/token × max_model_len × 1.08 + per-seq mamba pages |
+| runtime overhead | partly | `--expert-precise-memory` swaps default 7.60 GiB for the registry-fitted 5.25 GiB |
+
+Anything else is an IMAGE EDIT, not a deploy — say so; do not invent a flag
+(verify with `podman exec <ctr> grep -n getenv …/offloader/expert_activation_registry.py`).
+
+**UTIL LAW: 0.982, NEVER 1.00 (measured 2026-10-03).** The CLI field is
+`Field(gt=0, le=1)`, but the worker init demands `free > budget`: at 1.0
+budget == device total and BOTH ranks raise
+`ValueError: Free memory on device cuda:N (31.29/31.86 GiB …)` BEFORE a
+single weight loads — a crash loop (NRestarts ~2 min apart, zero payload
+progress). Not a knife-edge: **unbootable**. Even bootable near-ceiling
+shapes die under real load (0.13 GiB free bf16 boot; `0 bytes free` on a real
+995-token request).
+
+## 2. The CUDA-graph term: charge the measured capture
+
+Defaults (256 MiB base + 52 MiB/graph) over-charge badly. Measure with the
+engine's own post-capture line `Graph capturing finished … took X GiB` (per
+rank; heavier rank binds). Measured on the no-spec piecewise plan: 0.31/0.17
+GiB, and one boot reported a NEGATIVE −0.06 GiB delta (capture fit inside
+pages the profiler had already counted) — the analytic base pool is pure
+over-charge. Shipped: `BASE_MB=0`, `PER_GRAPH_MB=12` = 0.07 GiB — per-graph,
+so a spec-decode shape (18 graphs) still pays (0.21 GiB). An explicit
+`_ESTIMATE_MB` total does NOT scale with ladder changes; base+per-graph does.
+
+**Verify every deploy:** `Estimated CUDA graph memory` line vs the `Graph
+capturing finished` line; if capture exceeds the charge, raise `_PER_GRAPH_MB`
+back toward 52. Check `VLLM_CUDAGRAPH_*` actually present in
+`podman exec … env`.
+
+## 3. The pool is invisible to the plan; free VRAM is the estimator gap
+
+`--kv-cache-memory-bytes` does NOT appear in the arena arithmetic — the plan
+reserves the registry price, not the actual pool. Raising the pool consumes
+real free VRAM without growing the arena; the registry over-prices the pool
+(9190 B/token planned vs 7,891.8 measured at 200704 fp8 — 7,701 at 262144;
+**never reuse a B/token ratio across geometries**, and subtract ~3.87 MB
+block-alignment loss when converting a token target to bytes). The ask lands
+block-aligned: 3,166,500,000 B → 401,408 tokens; verify with
+`GPU KV cache size: N tokens, Maximum concurrency … X.Xx`.
+
+**Driver-reported free VRAM after hours of traffic is NOT allocatable
+arena.** It is the estimator gap: the registry over-prices KV and charges
+5.25 GiB overhead against ~2.5 measured; torch's allocator does not return
+slabs, so it reads as the high-water mark. The only reachable levers are util
+(within the law) and the graph charge; everything else needs a registry edit
+inside the image — the fork's own log line says as much.
+
+**MNBT is arena-free up to the anchor:** registry overhead =
+`base + 0.22 GiB × max(0, (nbt−4096)/1024)` anchored at nbt 4096, so rungs
+1024/2048/4096 are plan-identical (the fitted 5.25 GiB was fitted AT 4096).
+MNBT changes re-key the compile range (one recompile, ~24 s at (1,2048) with
+the mounted cache). 512 doubles TTFT at 4064 ctx; 12288 costs ~2.5 % plus
+arena. MNBT does not move the KV pool.
+
+## 4. Registry "compile headroom" is not reclaimable slack
+
+`--expert-precise-memory` selects the fitted overhead (5.25 GiB, this arch at
+TP=2) over the default (7.60 GiB = fitted + **2.35 GiB of compile and
+graph-capture headroom** the registry documents as "transient VRAM the
+profiler never sees"). It moves exactly one term — the plan's `room` — so the
+arena grows by that 2.35 GiB (~1,025 slots). **That headroom is the budget
+for the phase that allocates LAST**: reclaiming it requires paying elsewhere
+(smaller pinned pool, fewer sessions, shorter context). Measured 2026-10-01:
+bf16 2×262,144 + precise put the total at 31.73 of 31.86 GiB and the boot
+crash-looped at graph capture; dropping the flag restored ~2.4 GiB and booted.
+
+## 5. Boot ≠ survival (knife-edge shapes)
+
+A shape can pass EVERY boot gate — weights, profile, KV allocation, graph
+capture, `/health` 200 — and die on the first real request. Measured
+2026-10-01: `5 × 262144 @ fp8` booted (KV 1,350,182 tokens / 5.15x) and was
+killed seconds later by a 995-token prompt with `max_tokens=261149`:
+`torch.OutOfMemoryError: Tried to allocate 50.00 MiB … 0 bytes free`. After
+any knife-edge change: send a LARGE-`max_tokens` request before calling it
+done, and read post-boot free VRAM per rank (`rocm-smi --showmeminfo vram`)
+— the survivor had ~3.6 GiB free; the corpse had 0.
+
+**KV accounting — pin the pool BYTES, floor-sized:** set
+`--kv-cache-memory-bytes` PER RANK to the contract floor
+(`seqs × MAXLEN × measured B/token`), not the native window — extra pool bytes
+come out of the arena/headroom and buy nothing. Measured B/token on this
+hybrid: **7,701 fp8 / 13,839 bf16** (decomposed: attention 6,138/12,276 +
+dtype-independent mamba/side 1,563). Measured rates are shape-dependent —
+7,891.8 at the 200704×3 shape. Capacity does NOT scale with `SEQS`: the
+planner's KV reserve is for ONE max-model-len request.
+
+**Parallelism ceilings you cannot flag past:**
+
+- `--decode-context-parallel-size` refused for GQA when `TP ≤ num_kv_heads`:
+  *"requires TP (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 (it reuses TP ranks, not TP×DCP), so a 2-KV-head model
+  needs TP ≥ 4 = four GPUs.
+- EP (`--enable-expert-parallel` + `--all2all-backend`) exists but REPLACES
+  the fork's local tiered-offload gather with a per-layer PCIe all-to-all.
+- DP requires a full model copy per replica — on a model larger than the
+  card it is impossible, not slow.
+
+## 6. The context ladder (find the max bootable window by measurement)
+
+"Max possible" = the largest value that BOOTS, measured — never the model's
+spec maximum, never hand arithmetic.
+
+1. **Scale the pool with the window.** If KV_BYTES is pinned, it must shrink
+   in lockstep with MAXLEN or the rung tests nothing:
+   `KV_BYTES = round(KV_BYTES_ref × (seqs×MAXLEN_new) / (seqs×MAXLEN_ref))`
+   off a booted reference rung. Verify the rung's capacity still covers
+   `seqs × MAXLEN` from the engine's own line.
+2. **Boot under the PRODUCTION environment, not a shell probe** — a rootless
+   shell lacks `LimitMEMLOCK=infinity` and can pass where production OOMs.
+   Transient unit:
+   `sudo systemd-run --uid=<svcuser> --unit=probe-$ML -p LimitMEMLOCK=infinity -p Restart=no env <ENVFILE_OVERRIDE> <serve-script>`
+   pointing the serve script at a scratch env file via its `*_ENV_FILE` hook.
+3. **Judge on health + unit liveness:** poll `/health` (200 up / 503 loading
+   / 000 not bound); break early when the unit goes inactive — that is the
+   failure signal, not a timeout.
+4. **Capture the engine log per rung BEFORE teardown** (`podman logs` dies
+   with `podman rm`; a `podman logs` issued too soon after `podman run -d`
+   fails with *no container with that name* — record UNKNOWN, never FAIL).
+5. **Ladder down on FAIL, one bonus step UP on PASS.** Measured steps on this
+   box: OOM −16,384 tokens, bonus +4,096. Tiny margins (76 MiB class) mean
+   the next rung down almost certainly passes: `Tried to allocate 76.00 MiB …
+   0 bytes free … 30.43 GiB allocated by PyTorch` died in graph CAPTION;
+   `Tried to allocate 10.28 GiB … 9.46 GiB free` died in KV ALLOCATION.
+6. **Clean between rungs:** stop the transient unit, `podman rm -f`, kill
+   orphans by explicit PID
+   (`ps aux --sort=-rss | awk '/vllm\/bin\/python3/ && $6 > 50000000 {print $2}'`),
+   wait for `MemAvailable` to recover.
+
+**The hazard that cost production:** a leftover ladder script whose teardown
+`podman rm -f`s the production container fires against a freshly DEPLOYED
+engine. Teardown runs ONLY on failure, never after a pass; kill the whole
+scratch process tree and verify none remain BEFORE deploying. On PASS: print
+the measured `GPU KV cache size / Maximum concurrency` line, LEAVE IT
+SERVING, and pin the number into the repo (env + seam + harness
+contextWindow) before deploying.
+
+Cutover order: ladder → winner passes and serves → repo env + seam + harness
+→ tests → commit+push → verify no scratch scripts remain → stash foreign work
+(`git stash -u`) if the tree is dirty → deploy (one restart) → verify health
++ engine flags in the log.
+
+**Measured ladder on this box (200704×3, fp8 KV, precise memory):**
+
+| shape | util | graphs | arena | result |
+|---|---|---|---|---|
+| E | 0.98 | 0.55 | 17.22 GiB / 7,522 slots | boot ok |
+| F | 0.982 | 0.32 | 17.52 GiB / 7,653 slots | boot ok |
+| 1.0 | 1.00 | 0.07 | — | UNBOOTABLE (worker-init ValueError, both ranks) |
+| G (deployed) | 0.982 | 0.07 | 17.77 GiB / 7,762 slots | KV 401,408 tokens / 2.00x; 0.89 GiB real free/card held through a live 4,096-token generation at ~38–39 tok/s |
+
+bf16 ceilings at util 0.98: 3 seqs → 241,664 passes / 245,760 and 262,144 OOM
+at graph capture; 6 seqs fp8 → 10.70 GiB ask with 9.18 GiB free (fails) —
+~207k per context max.
+
+## 7. Arena audit procedure (when asked for "more experts")
+
+1. Read the live plan before proposing anything — `grep -oE` with a
+   digit-anchored tail (plain grep/journalctl truncate these columns to
+   `17.`):
+
+   ```
+   ssh dankserver 'sudo journalctl CONTAINER_NAME=frank-primary-qwen -b -o cat --no-pager \
+     | grep -aoE "(budget \(total x util\) +[0-9.]+|expert cache space +[0-9.]+ GiB +[0-9,]+ slots|Estimated CUDA graph memory.{0,80}|Graph capturing finished.{0,40}|GPU KV cache size.{0,90})"'
+   ```
+
+2. Classify each term (§1 table); take only the two reachable levers.
+3. Verify after deploy: plan lines show new budget/graphs/arena;
+   `GPU KV cache size` matches the ask; graph-estimate vs post-capture;
+   `rocm-smi` high-water per card = the real margin;
+   `systemctl show frank-primary -p NRestarts --value` = 0; a real chat
+   completion from a PEER (health-probe via `192.168.0.235:7770/health`, not
+   `localhost` inside an ssh session on the host — the latter returns `000`
+   and looks like an outage).

+
+## Chunked Prefill — the flag surface, and what it actually does
+
+**YES, the runtime exposes chunked-prefill options, and the running shape
+already uses them.** The tcclaviger fork is a vLLM fork, so the standard
+scheduler flags are present in the shipped image (verified by reading the
+`vllm.engine.arg_utils` and `vllm.config.scheduler` source in the live
+container `frank-primary-qwen`, not from a stub):
+
+| Flag | Default | What it controls |
+|---|---|---|
+| `--enable-chunked-prefill` | `True` in `SchedulerConfig`; the CLI arg is an auto-flag (`"default": None`) | whether prefill may be split into chunks |
+| `--max-num-batched-tokens` (MNBT) | 2048 (`DEFAULT_MAX_NUM_BATCHED_TOKENS`) | tokens processed per prefill iteration |
+| `--prefill-schedule-interval` | 0 | gap between prefill iterations |
+
+The running shape's argv carries `--max-num-batched-tokens 2048` alongside
+`--max-model-len 200704`, so chunked prefill is **ON and already active**: a
+200704-token prompt is prefilled in ~98 iterations of 2048 tokens, not in one
+shot.
+
+**It is a TTFT lever, not a throughput lever.** MEASURED 2026-09-29 on the
+ad hoc qwen-fp8 container (the same fork, same payload, same TP=2):
+
+- MNBT 8192 vs the default 2048: **neutral** on decode at every depth.
+- Small values re-chunk prefill only. They hurt TTFT (each chunk is its own
+  iteration, so the first token waits on more iterations) and they never touch
+  decode: a decode step is `max_num_seqs x (spec+1)` tokens, independent of
+  MNBT.
+
+**There is no `--ubatch-size` equivalent in vLLM.** `--ubatch-size` is a
+llama.cpp compute-buffer concept (`--batch-size`/`--ubatch-size`); the tcclaviger
+fork has no ubatch knob at all. The llama.cpp compute-buffer pair that frank-small
+was doubled on (2026-10-05, +4.6 % prefill at 8,928 tokens for 616 MiB) has no
+counterpart here, and the two backends should not be reasoned about by analogy.
+
+**MNBT is not a lever on this shape either.** The deployed 2048 is the fork's
+default, so a change is a deliberate departure from the shipped value, not a
+tune. The one thing MNBT does cost: every change re-enters the compile RANGE
+path, so `FRANK_PRIMARY_CACHE_DIR` pays one recompilation.

+
+**Evidence (live `podman logs frank-primary-qwen`, the 2026-10-04 18:19
+boot):** one 0.6 s burst at 18:46:07 PDT — 5.6 h into service, one
+running request, and the engine's own 18:46:08 log line reading
+"Prefix cache hit rate: 48.1%". 48 `gdn_hip` faults, then the

+[gdn_hip] ERROR: state fault report limit (32) reached; further faults
+  are counted silently
+```
+
+One physical SSM slot (42), two heads (3 and 8 — one per TP rank), 23
+GDN layers each, the state non-finite (NaN). The guard's own text in
+this build: *"known Qwen3.8-Flash-Next (QFN) flaw under prefix caching
+and is being actively worked; output quality for this request may
+degrade. Mitigation: --no-enable-prefix-caching."*
+
+**Mechanism.** With prefix caching on, the fork defaults QFN to
+`mamba_cache_mode=align` (boot log: "Mamba cache mode is set to 'align'
+for Qwen4ExpForConditionalGeneration … when prefix caching is enabled";
+`config/cache.py`: "none" is the no-prefix-cache mode, "all" is
+deprecated — align is the only sound mode WITH the flag). Align mode
+checkpoints each sequence's GDN (Gated DeltaNet) recurrent state into a
+mamba page per block and RE-SEEDS the state from that page when a
+request resumes from a cached prefix. The block size is raised to
+**3136 tokens** for the page-size equality (boot log: "Setting
+attention block size to 3136 tokens to ensure that attention page size
+is >= mamba page size" + "Padding mamba page size by 0.13% … exactly
+equal"). The corrupt state landed at the **13th boundary: 13 × 3136 =
+40,768 tokens** — the reported "~40k" mark. The NaN persisted in the
+mamba page, so every later turn of that conversation re-seeded the same
+non-finite state for those two heads (silently — the fault-report cap
+was already spent) while fresh short sessions looked fine.
+
+**RAM ruled out the same day** (the 2026-10-04 17:17 host reboot is when
+the current memory speed took effect): zero MCE/EDAC kernel records
+since boot; an 8 GiB in-band pattern check stable over 60 s under live
+load; 4800 MT/s is the JEDEC DDR5 floor on 5600 MT/s-rated DIMMs (not an
+overclock); and a two-head, single-slot NaN state is a state-path fault,
+not scattered finite bit corruption.
+
+**Fix.** `FRANK_PRIMARY_NO_PREFIX_CACHING=1` → `--no-enable-prefix-caching`
+(the fork-named mitigation; the flag renders in both directions from the
+knob so a fork default change cannot silently flip the contract). Cost:
+no prefix reuse — every turn re-prefills the whole history instead of at
+most 3135 tail tokens. A silently corrupted conversation is worse than a
+slower first token.
+
+**Verified 2026-10-05 (deploy b820d34):**
+
+- Engine argv carries `--no-enable-prefix-caching`; health 200; warm boot
+  `init engine … took 76.57 s` (the mounted compile cache is intact).
+- Boot plan unchanged, as predicted: expert cache **17.77 GiB / 7,762
+  slots** (the flag touches no plan term), CUDA-graph estimate 0.07 GiB
+  vs 0.08 GiB captured (inside the 12 MiB/graph charge).
+- `GPU KV cache size: 424,678 tokens` — **up** from 401,408 at the same
+  3,166,500,000 B ask: the pool now prices ~7,456 B/token (was 7,891.8),
+  the mamba/side per-token term dropping once the per-block checkpoint
+  pages are gone; the 3136 attention block-size raise nonetheless stays
+  (the page-size invariant is enforced in mode "none" too). Frank's
+  400,700-token floor is cleared with ~24k of headroom.
+- **Zero `gdn_hip` lines** in the boot-and-traffic window (only the two
+  INFO module banners mention the name).
+- Boundary probe (single request, no prefix reuse): prompt 39,280 +
+  completion 1,491 = **40,771 total tokens — across the 40,768 line**;
+  the task (write 1–400, one per line) completed coherently: 399 integers
+  parsed, 0.997 monotone, tail `… 398 399 400`. Pre-fix, this boundary is
+  exactly where the conversation degraded (the 13th 3136-page re-seed).
+- e2e: 32/33 pass; the one failure is the admin spec's
+  192.168.0.112:8989 leg with FrankBook-Pro asleep (environmental,
+  unrelated to this change; re-run `tests/e2e/run.sh` once the mini is up).
+
+**RESULT — REVERTED THE SAME DAY.** With every mechanical check green
+(zero faults, coherent 40,771-token probe), live long conversations
+STILL degraded at ~40k on the running endpoint (Frank, direct
+observation). The container serving that window (`--no-enable-prefix-
+caching`, booted 2026-10-05 12:47 PDT) logged ZERO `gdn_hip` faults
+while the corruption reproduced — so this recurrence is **fault-free**:
+the NaN-state guard did not fire, which the re-seed theory requires.
+Open hypotheses, in order: (1) the poisoned transcript is being re-fed —
+corrupted assistant turns already in the history keep producing
+corrupted continuations even with perfect state, so the same
+conversation cannot distinguish fixed from unfixed; (2) a second
+long-context mechanism with no guard coverage — fp8 KV degradation at
+depth is the next suspect (a bf16-KV boot costs ~2× the pool per token
+and would settle it). Prefix caching is **back ON**
+(`FRANK_PRIMARY_NO_PREFIX_CACHING` commented out — the cost bought no
+fix). The knob and the serve branch stay for a future fork build with a
+fixed GDN path. Next diagnostic: reproduce on a FRESH conversation; if
+it still breaks at ~40k with zero faults, A/B the KV dtype.
+
+**RESOLVED (2026-10-05 evening): it was the RAM.** Frank dropped the
+memory from 4800 to **4600 MT/s** (in effect since the 2026-10-05 12:21
+PDT host boot) and the corruption stopped: zero `gdn_hip` ERROR lines in
+the container since, zero MCE records, and the live agent session on
+this endpoint past 140k context, "comfy cozy" (Frank). Marginal DDR5 on
+four DIMMs is a common cause for BOTH eras: the 2026-10-04 NaN burst
+(corrupted weight/activation traffic poisoning a GDN state write — the
+guard-visible path) and the fault-free ~40k degradation (silent flips in
+KV/expert data, which no guard covers on non-ECC memory). The re-seed
+theory is therefore UNPROVEN, not disproven — the entire caching
+experiment ran on marginal RAM and was confounded on both arms.
+Post-mortem on the rule-out: consumer non-ECC RAM raises no MCE for a
+silent flip; a 60 s / 8 GiB pattern sample covers ~0.5 % of 246 GiB;
+"4800 is the JEDEC floor on 5600-rated DIMMs" is a rating, not a
+stability proof at four-DIMM loading. The revert test was the decisive
+instrument and it pointed at the RAM all along. Prefix caching stays ON
+(zero faults under heavy re-send traffic since the speed drop); the knob
+stays for a future fork fix. The fp8-KV A/B is NOT needed.
+
+### Shape F/G (2026-10-03): where the free VRAM actually is, and what forcing it cost
+
+`rocm-smi` showed **3.57 GiB free per R9700** at the deployed shape E (28.28 GiB
+used of 31.86 GiB, after hours of real traffic — so it is the high-water mark,
+not an idle artifact). Growing the expert arena into it is NOT a matter of
+raising `--gpu-memory-utilization`, because the arena is
+
+```
+arena = budget - non-expert - KV reserve - CUDA graphs - runtime overhead
+budget = device_total x gpu_memory_utilization          # expert_plan.py:567
+```
+
+and every term on the right is either fixed or a lie:
+
+| term | plan charges | measured reality | reachable from our side? |
+|---|---|---|---|
+| `budget` | 31.22 GiB (0.98) | field is `le=1` so 31.86 GiB is the field max, but 1.0 is UNBOOTABLE (below) | **yes** — shipped 0.982 |
+| `non-expert weights` | 6.28 GiB | checkpoint census | no |
+| `KV reserve` | 1.91 GiB (registry 9,190 B/token x 200704 +8%) | real pool bills 2.93 GiB at 7,892 B/token | no (registry constant) |
+| `CUDA graphs` | 0.55 GiB = 256 MiB + 52 MiB x 6 | `Graph capturing finished in 3 secs, took 0.31 GiB` | **yes** — `VLLM_CUDAGRAPH_MEM_BASE_MB` / `_PER_GRAPH_MB`; `VLLM_CUDAGRAPH_MEM_ESTIMATE_MB` pins the whole term outright (checked first, pair ignored when set) |
+| `runtime overhead` | 5.25 GiB (`--expert-precise-memory`) | far lower at idle | no (registry constant) |
+
+Shape F took the graph term (0.55 -> 0.32 GiB) and nudged util to 0.982:
+**arena 17.52 GiB / 7,653 slots measured**, +131 slots. Shape G takes the
+graph term further (0.32 -> 0.07 GiB) at the same util.
+
+**Shape G takes the graph term to the measured floor, util to the law.** The
+graph base pool is the actual over-charge: shape F's own boot reported
+`Graph capturing finished in 4 secs, took -0.06 GiB` — a **negative** capture
+delta, so the 256 MiB base was fiction. Charging `0 base + 12 MiB/graph`
+(0.07 GiB for the shipped 6-graph plan, and still per-graph so an 18-graph
+spec-decode shape pays 0.21 GiB) lands the plan at budget 31.29 / graphs 0.07 /
+**arena 17.77 GiB / 7,762 slots measured**. The KV ask went to
+`3,166,500,000` B/rank, which the engine's own 7,891.8 B/token price lands at
+**401,408 tokens measured / 2.00x concurrency** — the first shape holding two
+full-length conversations with real spare. (The ask/landed delta is block
+alignment: 196 x 2048. The price is shape-dependent, 7,701 B/token at 262144.)
+
+**UTIL 1.00 is not a knife-edge on this fork, it is UNBOOTABLE — measured
+2026-10-03.** One deploy took the field maximum to buy the last 0.57 GiB of
+arena; both workers refused init BEFORE loading a single weight, twice:
+`ValueError: Free memory on device cuda:N (31.29/31.86 GiB ...)` — the worker
+demands free > budget and budget == total, so `le=1` on the CLI field is a
+trap: the engine dies in a 2-restart crash loop with zero payload progress.
+So `0.982` is a LAW, not a preference, and the "why 0.982" answer now has two
+proofs: this ValueError, and the historical ceiling deaths (the 2x262144 bf16
+boot at 0.13 GiB free; the 5x262144 boot at "0 bytes free" on a real
+995-token request). Everything beyond ~7,912 slots needs the registry edited
+inside the image (the fork's log line says exactly that: *"Update the
+registry entry if this drifts"*), not a deploy.
+
+**The host region was the last arena-plan term still autofitting per boot —
+now it is a literal (2026-10-04).** With no `--expert-offload-mem` the planner
+binds the host region to `MemAvailable` AT BOOT minus `PLE 47.68 - 2 x 7.0
+process - 5.0 api/engine - 5% margin`: the 2026-10-05 boot read 237.97 GiB and
+offered 159.39 GiB usable, while the same host reads **75.4 GiB available while
+running** — the bound tracks whatever the co-tenants hold at that moment. The
+demand is 105.48 GiB (52.74 GiB/rank x 2, 23,040 swap-target experts), and a
+boot where the bound drops near it silently converts next-hottest experts to
+VRAM-only (the `pinned_extra` warning is the only trace).
+`FRANK_PRIMARY_EXPERT_OFFLOAD_MEM=120` pins it: measured demand + 14% headroom,
+on a host with 246.1 GiB total. Semantics verified in the shipped image
+(`offloader/expert_plan.py`): the cap binds as the bound, an exceedance only
+warns, and the plan rewrites the field to the cap it met (+1 MiB/rank).
+
+**MNBT 1024 -> 2048 is free on every axis the plan can see.** The registry
+overhead model is `base + 0.22 GiB x max(0, (nbt - 4096)/1024)` anchored at
+nbt 4096, so any rung up to 4096 charges the identical 5.25 GiB; the fitted 5.25
+was itself fitted at nbt 4096, which means 2048 is covered by an activation
+figure measured at a **larger** batch. SEQS 3 boots at both 1024 and 2048
+(measured 2026-10-02 — the `query_start_loc` `ConstraintViolationError` is a
+SEQS property). The costs are a one-time recompile (the compile **range** is
+part of the cache key, so `FRANK_PRIMARY_CACHE_DIR` pays once) and a wider
+prefill chunk, which the 09-29 sweep found decode-interchangeable across
+1024-4096 while 512 doubled TTFT at 4064 ctx (2.46 s vs 1.36 s).
+
+**`--expert-precise-memory` is the arena lever that does not touch the window.**
+It attacks the planner's overhead term (shape F above attacks the graph term —
+the third and last term this repo can reach), and the flag swaps the default
+registry figure for the fitted one. Measured
+2026-10-02 by a boot probe on the shape-D base (production stopped, candidate
+booted AS the service; numbers are the engine's own plan lines):
+
+| plan line | shape D | **shape E** |
+|---|---|---|
+| `runtime overhead (non-torch + buffers + activation)` | 7.60 GiB | **5.25 GiB** (`precise (gfx1201 TP2 nbt4096/seqs16/len262144)`) |
+| `expert cache space` | 14.87 GiB | **17.22 GiB** |
+| slots | 6,496 | **7,522** (+1,026, +16%) |
+| `swap region` | - | 13.7 GiB / 5,986 slots, 133-134 per layer |
+| boot | - | healthy in 420 s, no OOM |
+
+`'expert_precise_memory': True` also appears in `non-default args`, so a silent
+argparse drop is visible in the boot log. The flag lands **in the arena, not the
+pool** - `--kv-cache-memory-bytes` is untouched at 3.15e9/rank (option A), because
+the pool is not an arena lever and cutting it further would only cost
+concurrency: a 2.2e9 pool was probed in the same window and reports 277,686
+tokens / **1.38x**, so it is the conservative fallback if free VRAM ever binds,
+not the shipped value.
+
+**The compile cache is a boot-cost fix, and it was worth 173 s per boot.**
+Measured 2026-10-02: the image ships **no `/root/.cache` at all** (a fresh
+container: `No such file or directory`), and after a boot that directory holds
+`vllm` at **1,154,714,333 B in 4,665 files** plus `comgr` at 229 MB, all inside
+the container's ephemeral layer. Every
+`podman rm -f` - i.e. every deploy, restart and reboot - discards it, and the
+engine re-pays:
+
+```
+Using cache directory: /root/.cache/vllm/torch_compile_cache/b265bd396a/rank_0_0/backbone
+Dynamo bytecode transform time: 4.99 s
+Compiling a graph for compile range (1, 1024) takes 173.19 s
+saved AOT compiled function to /root/.cache/vllm/torch_compile_cache/torch_aot_compile/…
+torch.compile took 181.20 s in total
+init engine (profile, create kv cache, warmup model) took 217.26 s (compilation: 181.20 s)
+```
+
+Mounting a host directory at `/root/.cache` makes every later boot load the AOT
+artifact instead. The mount is deliberately the **parent**, not
+`/root/.cache/vllm`: `VLLM_CACHE_ROOT` defaults to the `vllm` child, and
+`comgr` is the HIP-kernel JIT cache, so one mount persists both — and it hides
+nothing, because the image ships no `/root/.cache`. The cache key
+includes the compile range, so the MNBT choice costs exactly one compilation.
+Entries are version- and config-hashed: a stale entry is a miss, never a wrong
+answer.
+
+**Proven live on the deployed endpoint, 2026-10-02, consecutive boots of this
+exact shape:**
+
+| boot | engine log |
+|---|---|
+| cold (deploy) | `Compiling a graph for compile range (1, 1024) takes 179.24 s` → `torch.compile took 188.26 s in total` |
+| warm (restart) | `Directly load the compiled graph(s) for compile range (1, 1024) from the cache, took 2.143 s` → `torch.compile took 3.97 s in total` → `init engine (profile, create kv cache, warmup model) took 41.13 s (compilation: 3.98 s)` |
+
+The host directory held **1.4 GB in 4,707 files** after the cold boot. Time to
+`/health` is dominated by the 172.8 GiB payload load (the warm boot reached
+health in 490 s), so the win is the ~184 s of inductor/AOT build rather than a
+proportional cut in boot time.
+
+`GPU_MAX_HW_QUEUES=2` caps the HSA hardware queues per GPU. Verified a real knob
+rather than a no-op - the literal is read out of
+`/opt/rocm/core-10.0/lib/libhsa-runtime64.so` - and shipped deliberately
+alongside the 32x64 gather geometry. It is **not** A/B measured.
+
+**The pool, not the slot count, sets how many conversations live at once.**
+Measured live at this shape: `GPU KV cache size: 398,658 tokens, Maximum
+concurrency for 200,704 tokens per request: 1.99x` (3,146,129,408 B reserved).
+The per-token price is **shape-dependent**: the 262144 shape priced at 7,701
+B/token (6,100,000,000 B -> 792,069 tokens), this pool at 7,892 - ~2.5% dearer,
+so a concurrency figure never extrapolates across geometries. The endpoint
+advertises 3 slots: a third LONG request queues rather than being refused, and
+shorter requests use the spare blocks. Verified: three concurrent 67-token
+requests answered in parallel, ~4.1 s each. Two contexts at 200704 are a
+capacity contract, not a throughput one (2-way concurrency summed BELOW parity
+at 4064 ctx).
+
+#### `--max-num-seqs 2` is impossible on this model (measured 2026-10-02)
+
+Four single-variable boot probes against the then-deployed shape, production
+stopped for each:
+
+| MAXLEN | SEQS | MNBT | result |
+|---|---|---|---|
+| 262144 | 2 | 1024 | **Engine core initialization failed** |
+| 262144 | 2 | 2048 | **Engine core initialization failed** |
+| 262144 | 3 | 1024 | healthy - 792,069 tokens, 3.02x, arena 6,248 |
+| 262144 | 3 | 2048 | healthy - the then-deployed incumbent |
+
+The failure is `torch.fx.experimental.symbolic_shapes.ConstraintViolationError:
+Constraints violated (L['query_start_loc'].size()[0]) ... specialized it to be
+a constant (3)`, raised from AOT `build_guards(strict_error=True)` during
+`determine_available_memory -> profile_run -> _dummy_run`. `model_runner.py`
+sizes that input buffer `max_num_reqs + 1` and `_dummy_run` sets
+`num_reqs = min(max_num_batched_tokens, max_num_reqs)`, so the width is
+`SEQS + 1` for ANY `MNBT >= SEQS`: 3 at SEQS 2, 4 at SEQS 3. **MNBT is not a
+lever here** - it only moves the compile RANGE ((1,1024) vs (1,2048)), which
+is why the identical error appears at both rungs. `--enforce-eager` bypasses
+the path at the cost of CUDA graphs. The same failure class killed the
+2026-10-01 bf16 2 x 262144 shape.
+
+#### The arena lever is `max_model_len`, not `--kv-cache-memory-bytes`
+
+The fork's planner sizes expert cache as `budget - non-expert - KV reserve -
+graphs - overhead`, and the KV reserve is registry-priced at **9190 B/token x
+max_model_len** - not from the `--kv-cache-memory-bytes` value:
+
+| MAXLEN | KV reserve | arena |
+|---|---|---|
+| 262144 | 2.48 GiB | 14.30 GiB / **6,248 slots** |
+| 200704 | 1.91 GiB | 14.87 GiB / **6,496 slots** |
+
+D(reserve) 0.57 GiB = D(arena) 0.57 GiB = +248 slots. The 6.1e9 -> 3.15e9
+pool cut (2.75 GiB) bought **zero** arena slots. It buys runtime HEADROOM,
+which is still worth having - the shape it replaced died with `0 bytes free`
+on a real 995-token request. Grow the arena by lowering `max_model_len`, or by
+taking the overhead term with `--expert-precise-memory` (below); the pool is the
+headroom lever only.
+
+#### The other arena lever: `--expert-precise-memory` (overhead 7.60 -> 5.25 GiB)
+
+The flag is now ON. It was refused on 2026-10-01 for a reason that does not
+generalize: the 2 x 262144 bf16 shape was already at the ceiling (weights 6.28 +
+pool 6.80 + graphs 0.55 + arena 16.65 + non-torch ~1.45 = 31.73 of 31.86 GiB,
+NRestarts=3 at ~6.7 min each), so the 2.35 GiB the flag moves into the arena was
+the last stack over the line, not the cause. The plain bf16 2 x 262144 boot 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 `Tried to allocate 50.00 MiB
 ... 0 bytes free`.
 
-The correction is a pool cut, not a downgrade. fp8 costs 7,701 B/token
-(measured 6,138 attention + 1,563 mamba/side, dtype-independent), so 2 x
-200704 = 401,408 tokens needs 3.091e9 B; pinned at 3.15e9, ~44 MB of margin

+At 200704 x 3 the flag fits with room and is worth **+1,026 slots (+16%)**. What

+DEVICE-resident, the pool is not part of the budget's arithmetic, and the 200704
+window's KV reserve (1.91 GiB) plus a smaller attention footprint is what the
+plan needed. The pool stays at 3.15e9/rank deliberately (option A) - cutting it
+further would cost concurrency (2.2e9 -> 1.38x) and buy no slots.

+# frank-large — halogen container, Qwen3.8-27B + DFlash2 (Dankclaw, ACTIVE 2026-10-05)
+
+frank-large is the Strix Halo iGPU endpoint on Dankclaw (`:7770`). Since
+2026-10-05 it runs the **halogen** engine — `ghcr.io/peonist-ai/halogen` at a
+pinned digest, launched by `scripts/serve-frank-large.sh` under a root
+systemd unit as a podman container — serving
+**`peonist-ai/halogen-qwen3.8-27b`** (`qwen3.8-27b-p1w4d-d2.hgn`,
+35,865,565,184 B ≈ 33.4 GiB, sha256 `274c3fc7…`, 1352 tensors) with the
+**DFlash2** drafter at **one slot x 200,700 ctx**.
+
+It replaced the ROCmFPX llama.cpp fork endpoint ([[frank-large-rocmfpx-q6agent-uncensored-mtp]]),
+which remains the rollback target with its payload on disk.
+
+## Why swap

+|Format|GGUF (fork-private tensor types 102/103)|`.hgn` — loads in NO other engine|
+
+The swap was accepted with eyes open on two product regressions, both
+confirmed by Frank before deploy:
+
+1. **Text-only.** halogen loads the language tower only; README "honest
+   limits": *"The vision encoder is ignored; image inputs are not supported."*
+   The mmproj-era vision role moves wholly to frank-small.
+2. **Censored base.** The checkpoint is a finetune of the censored
+   `Qwen/Qwen3.8-27B` base, built to make its DFlash2 head strong. The
+   ROCmFPX AGENT file was an *Uncensored* build; refusals can return.
+
+## Shape and why
+
+`scripts/frank-large.env` carries every tunable with its evidence; the load-
+bearing numbers:
+
+- **`HALOGEN_KV_SLOTS=1` + `HALOGEN_DRAFTER=2`** — the engine offers batch OR
+  speculation, never both (FLAGS.md: "Batching and speculation are exclusive:
+  a step batches when more than one conversation is running, so the drafter
+  stays off with more than one slot"). Slots>1 silently loses DFlash2; the
+  sibling halogen engine measured 41 -> 14 t/s when slots went up. frank-large
+  was a one-conversation endpoint before (PARALLEL=1), so the contract holds.
+- **`HALOGEN_SLOT_CTX=200700`** — the per-conversation HARD ceiling: a longer
+  prompt is a 400 naming the limit, never a truncation. The harness side is
+  wired to it: `models.yml` `contextWindow: 200700`, and OMP compacts at 70%
+  = 140,490, leaving 60,210 of the slot for the reply.
+- **`HALOGEN_MAX_TOKENS_CAP=65536` + `HALOGEN_QUEUE_TIMEOUT=7200`** — coupled
+  pair (FLAGS.md table): a request at the cap must not outlive the timeout.
+  65536 > the harness's 57,344 `maxTokens` so an eager request never meets
+  the engine's 400.
+- **KV math:** 1 slot x 200,700 x 64 KiB/token (d2 KV = 2x fp8) = 12.2 GiB
+  pool, inside the ~65 GiB left after 33.4 GiB mmap'd weights + engine working
+  set + host baseline on the 121.2 GiB box. The engine sizes the pool itself
+  and **prints a boot ledger naming any clamp** — the post-deploy check reads
+  that ledger, not a formula.
+- **No server-side sampler:** an absent temperature is GREEDY. The card's
+  thinking recipe (temp 1.0 / top_p 0.95) lives in `models.yml` `extraBody`
+  — on the wire only. The template defaults `reasoning_effort` to **xhigh**
+  when a request sends none, and **thinking tokens consume the
+  `max_tokens` budget**: a budget exhausted mid-thought returns
+  `finish_reason: "length"` with EMPTY `content` and the partial reasoning
+  in `reasoning_content` — clients must read both fields.
+
+## Client contract deltas vs llama.cpp
+
+|Behavior|halogen|
+|---|---|
+|Prompt over slot|400 naming the limit (no truncation)|
+|`max_tokens` over cap|400 naming the limit (never silent truncation)|
+|full-length request outliving `HALOGEN_QUEUE_TIMEOUT`|503s for everyone queued|
+|`timings`|every response carries llama-server-shape `timings` (`draft_n`, `draft_n_accepted`) — the drafter check reads the RESPONSE, and it proves speculation fired|
+|`response_format`|NOT supported (no constrained decoding)|
+|thinking field|`reasoning_content` (same as before)|
+|`reasoning_effort`|same Qwen3.8 template; outside {xhigh,medium,low} rejected — models.yml fold stays; unset defaults to xhigh, `none` disables thinking|
+|tools|server-side tool calls advertised — round-trip MUST be re-probed after deploy|
+|image input|ignored/error — route to frank-small|
+
+## Deploy mechanics
+
+- **Image:** `ghcr.io/peonist-ai/halogen@sha256:dc0a39a0016d6cfc58a197978febaafdf8d28403f724ded6111d98b5fb7ac0ea`
+  (published tag 0.1.4). The deployer gates the exact digest exists in podman
+  storage before dispatch. NOT the 2026-09 `halogen-flash-server` repo — that
+  was the Flash-Next w4b era, different image, retired.
+- **Payload:** `scripts/download-frank-large-halogen.sh` (fetch law: `curl -f`,
+  exact byte count, LFS sha256 where the Hub publishes one, `--verify-only`,
+  token never in argv) into `/home/dank/models/halogen-qwen3.8-27b/`. The
+  tokenizer is a FLAT DIRECTORY (`tokenizer/`, 5 files — tokenizer.json,
+  vocab.json, merges.txt, chat_template.jinja, tokenizer_config.json),
+  mounted whole at `/tokenizer`; the engine's `HALOGEN_TOKENIZER` default is
+  that directory, so the container gets no tokenizer flag (model-card
+  docker-run parity). The deployer and serve script refuse a missing file or
+  ANY symlink: an HF cache snapshot symlinks each entry into `blobs/` and
+  those links dangle inside the container mount.
+- **Unit:** `scripts/frank-large.service` (root, `User=dank`, relinked into
+  `/etc/systemd/system/`), `ExecStart` = serve script, `ExecStop` = `podman
+  stop -t 120 frank-large-halogen`, script `exec podman wait` so
+  `Restart=always` is real. Engine stdout goes to
+  `/home/dank/logs/frank_large.log` (the boot ledger lives there, not in the
+  journal).
+- **Cutover:** `deploy_llm_large` in `scripts/deploy-remote.sh` sweeps the
+  legacy bare `llama-server --model /home/dank/models/kingjones-*` process and
+  the legacy `frank-large` container name by NAME (never `pkill -f
+  llama-server` — that hits frank-small), retires the old quadlet if the 2026-09
+  halogen era's unit lingers, waits port 7770 free, relinks, health-gates.
+- **Bench law:** stop+mask the unit before any GPU experiment on this box
+  (AGENTS.md); `/health` answers 503 while the 33.4 GiB payload loads — that
+  is loading, not failure.
+
+## Verification (post-deploy checklist)
+
+1. `grep -iE 'clamp|kv|pool|drafter|dflash' /home/dank/logs/frank_large.log`
+   — ledger shows the pool at the asked shape, DFlash2 active, NO clamp line.
+2. `curl -s http://192.168.0.143:7770/health` -> 200.
+3. Real completion with `reasoning_effort` + temp/top_p from the wire recipe;
+   `reasoning_content` populated; decode rate from the timings.
+4. Spec decode fires: multi-token step behavior visible in rate; compare
+   against DRAFTER=0 arm if in doubt (never against gufo — bench law).
+5. Harness round-trip: an OMP call through `llamacpp (dankclaw)/frank-large`
+   incl. a tool call (V1TOOLS).
+6. Prompt > 200,700 tokens returns the 400 naming the limit (contract test).
+
+## Rollback
+
+Revert the frank-large swap commit and redeploy `dankclaw --service frank-large`:
+the ROCmFPX payload (`/home/dank/models/kingjones-Qwen3.8-27B-ROCmFP4-STRIX-MTP/`),
+the fork build (`/home/dank/GitPackages/kingjones-ROCmFPX/build`), and its
+`scripts/build-rocmfpx.sh` pin (commit `36e9acd`, seam-tested) all remain on
+disk. The halogen payload can stay: it costs nothing while the unit points
+elsewhere.

+
+## Identity
+
+| | |
+|---|---|
+| Host / device | Dankclaw (192.168.0.143), Radeon 8060S iGPU `gfx1151`, ~114 GiB GTT aperture |
+| Endpoint | `http://192.168.0.143:7770` — alias `frank-large`, `/v1` OpenAI surface |
+| Runtime | **`kingjones30/ROCmFPX`** llama.cpp fork @ `36e9acd40e10a87cd3c3ef8ec734668757dc8520`, built by [`scripts/build-rocmfpx.sh`](../../scripts/build-rocmfpx.sh) — unchanged from the Q8 era; the fork already knew type 102 |
+| Unit | root systemd `frank-large.service` ([`scripts/frank-large.service`](../../scripts/frank-large.service)), `User=dank`, `Restart=always` |
+| Serve script | [`scripts/serve-frank-large.sh`](../../scripts/serve-frank-large.sh) (owns the argv), tunables [`scripts/frank-large.env`](../../scripts/frank-large.env) |
+| Weights | `/home/dank/models/kingjones-Qwen3.8-27B-Uncensored-ROCmFP4-STRIX-MTP/Qwen3.8-27B-Uncensored-Q6_0_ROCMFPX_AGENT.gguf` — 24,856,607,008 B, sha256 `e966deb3…` |
+| Draft | `…/mtp-Qwen3.8-27B-Q4_0.gguf` — 1,680,271,648 B, sha256 `051a1764…` (byte-identical to the aligned repo's head; hardlinked, not re-downloaded) |
+| Projector | `…/mmproj-Qwen3.8-27B-BF16.gguf` — 931,145,888 B (hardlinked from the aligned payload dir; the same file the Q8 era served) |
+| Fetch | [`scripts/download-frank-large-kingjones-uncensored.sh`](../../scripts/download-frank-large-kingjones-uncensored.sh) — hardlinks the draft/projector from the aligned dir when present, otherwise fetches; `-f`, byte-count + LFS sha256 verified, `--verify-only`, token never on the command line |
+| Seam | `tests/frank_large_unit.bats` (payload gates, deployer/serve parity, spec block, KV dtype) |
+
+## Why this file
+
+`kingjones777/Qwen3.8-27B-Uncensored-ROCmFP4-STRIX-MTP-GGUF` ships the same
+"protected heads" construction as the aligned repo, in the uncensored tuning.
+Parsed header of the deployed file:
+
+| Field | Value |
+|---|---|
+| ftype | **114** — the fork's 64-bit-block family, ≈7.44 bpw |
+| Tensor mix | 353 F32 + **339 type-102 (`GGML_TYPE_Q6_0_ROCMFPX`)** + **159 type-103 (`Q8_0_ROCMFPX`)** |
+| Protected heads | 64 output-head tensors kept at plain precision — the AGENT construction from the aligned repo, at the 6-bit rung |
+| Arch | qwen35, 64 layers, `full_attention_interval 4`, `context_length 262144` |
+| Embedded sampling recipe | temp 1.0 / top_p 0.95 / top_k 20 |
+
+The same lock-in law as the Q8 era applies: types 102 and 103 exist in no
+loader but this fork; stock llama.cpp and gufo refuse the file at load
+(`unknown tensor type`). The loader was not re-litigated — the file picks the
+runtime, and the pin in `scripts/build-rocmfpx.sh` (commit by SHA) stays.
+
+Rejected sibling: `Q6_0_ROCMFPX_LEAN` (6.45 bpw, no protected heads) — the
+protection is what keeps the output-head logits at full precision and the
+drafter accurate, so it stays deployed.
+
+## Shape and budget
+
+Unchanged from the Q8 era — the swap was payload-only:
+
+| Dial | Value | Why |
+|---|---|---|
+| `--ctx-size` | 262,144 | the native window, no rope scaling |
+| `--parallel` | 1 | one conversation, all memory to it |
+| KV dtype | **f16** (both K and V) | ~64 KiB/token; free inside a 114 GiB aperture |
+| `--fit off` | on | the auto-fitter would silently resize the window |
+| `--flash-attn on` | on | required for the long-window attention path |
+| `--direct-io`, `--ctx-checkpoints 16`, `--cache-ram 8192`, `--cache-idle-slots`, `--jinja`, `--reasoning on --reasoning-format deepseek --reasoning-budget -1` | | same as [[frank-large-rocmfpx-q8agent-mtp]] |
+
+Spec decode: `--spec-type draft-mtp`, the repo's `mtp-Qwen3.8-27B-Q4_0.gguf`,
+`--spec-draft-n-max 4`, pinned `--spec-draft-device ROCm0`.
+
+Measured steady state: GTT **~61 GiB** under live load (host baseline 16.7),
+boot to `/health` **~15 s**.
+
+## Measured on this payload (2026-10-03, production service, `/completion` timings, temp 0, `cache_prompt: false`)
+
+| Traffic | Decode t/s | Prefill t/s | Draft acceptance |
+|---|---|---|---|
+| Prose, 4,813-token prompt, 512 tokens | **27.57 / 28.10** (two runs) | ~205–217 | **396/456 = 0.868** → mean acceptance length ≈ 4.4, i.e. drafting at nearly the full n-max 4 |
+| Schema echo (structured repetition) | **31.44** | — | 639/639 = 1.000 |
+| Block copy (text repeated verbatim) | ~28.0 | — | 0.848 |
+
+vs the Q8 era's 0.462 acceptance at a 2,202-token prompt: the MTP head drafts
+materially better on this file. The card's claimed 0.953-class acceptance is
+no longer science fiction on real prose — but keep reading it as a file
+property, not a throughput promise.
+
+## The ngram-mod chain — measured and rejected
+
+Frank's ask: layer `--spec-type draft-mtp,ngram-mod` on top of MTP for an
+extra gain. Measured in three bench windows (production service stopped per
+the benchmarking law; artifacts `/home/dank/fl-ngram-ab/` on Dankclaw),
+comparing `draft-mtp` alone vs the chain on the same traffic:
+
+| Traffic | MTP alone | MTP + ngram-mod | Delta |
+|---|---|---|---|
+| Prose | 27.57 t/s | 23.40 t/s | **−15 %** |
+| Block copy | 28.0 t/s | 26.1 t/s | **−7 %** (with ngram-mod demonstrably firing: 138 proposals/run) |
+
+Mechanism, straight from arm B's boot log:
+
+```
+recurrent state rollback is not compatible with 'ngram-mod' - disabling rollback support
+```
+
+On the qwen35 hybrid (Gated DeltaNet recurrent layers) adding the ngram layer
+disables the rollback path MTP's own verification relies on, so acceptance —
+and throughput — drop on *all* traffic, even where the ngram matcher fires.
+**Deployed decision: `draft-mtp` alone.** Chaining is not free on recurrent
+models; the fleet law in `AGENTS.md → llama.cpp serving` records it.
+
+## Bench-window hardening laws (learned building the A/B)
+
+1. **Health 200 is not proof of ownership.** After boot, verify the pid you
+   started owns the port (`ss -ltnp`); a zombie server from a prior window
+   answers `/health` too and silently serves your arm.
+2. **Kill scratch servers with SIGKILL after a grace period.** llama-server's
+   graceful SIGTERM waits on open keep-alive connections — a harness holding
+   the socket leaves the process (and its ~24 GiB of GTT) alive after the
+   script exits.
+3. **Prove the port is free and GTT dropped between arms**, or the second
+   arm measures a collision.
+
+## Client contract
+
+Unchanged from the Q8 era and re-verified on this payload 2026-10-03: model id
+`frank-large`, native tools, thinking in `reasoning_content`,
+`reasoning_effort` ∈ {xhigh, medium, low} only (anything else HTTP 500),
+card-recipe sampling defaults server-side, vision through the BF16 projector
+(red PNG → **`Red`**, 74 prompt / 165 completion tokens). The traps list —
+`content: null` when reasoning eats the budget, the self-recovering MTP
+boundary log line, `enable_thinking:false` not `reasoning_effort:"none"` — is
+in [[frank-large-rocmfpx-q8agent-mtp]] and still applies.
+
+Sweep key for scratch servers is now the payload name:
+`pkill -f 'Qwen3.8-27B-Uncensored-Q6_0_ROCMFPX_AGENT'` — never `pkill -f
+llama-server` (frank-small is also one).
+
+## Operations
+
+```bash
+./scripts/deploy.sh dankclaw --service frank-large
+systemctl status frank-large
+journalctl -u frank-large -n 200 --no-pager
+scripts/download-frank-large-kingjones-uncensored.sh --verify-only
+```
+
+## Rollback
+
+| Target | How |
+|---|---|
+| **ALIGNED Q8_0_ROCMFPX_AGENT** (previous shape, 17 t/s) | the payload dir `/home/dank/models/kingjones-Qwen3.8-27B-ROCmFP4-STRIX-MTP/` is untouched on disk; revert the swap commit (unit/env/serve trio) and redeploy, or point `FRANK_LARGE_MODEL_FILE` + `LLM_LARGE_MODEL_FILE` at the old paths. Verify with `scripts/download-frank-large-kingjones.sh --verify-only` |
+| gufo Q4_K_XL era | git tag `frank-large-gufo-q4kxl-20261001`, **but the gufo payloads (UD-Q4_K_XL 16.35 GiB, UD-Q8_K_XL + DFlash2 drafter) were removed from disk 2026-10-03 with Frank's approval** — this rollback now requires re-download per [[frank-large-gufo-qwen38-27b]] |
+
+## When it misbehaves
+
+Same decision tree as [[frank-large-rocmfpx-q8agent-mtp]]:
+`unknown tensor type` ⇒ off the pinned fork; SIGSEGV in
+`ggml_compute_forward_set_rows` ⇒ pre-`36e9acd` build; slow decode with no
+error ⇒ draft not engaged (`draft_n` in `/completion` timings) or an orphaned
+second copy eating GTT (`/sys/class/drm/card1/device/mem_info_gtt_used`);
+500 naming Jinja ⇒ `--jinja` lost; 500 naming the template ⇒ unmapped
+`reasoning_effort` in `models.yml`.

-> contract, then **resized twice the same day** on Frank's orders: first to

-> card free. Frank's arithmetic request — "as much as can fit while keeping
-> overhead open space to 2-3gb on the 3090" — is answered by the two
-> measurements in *Shape and the KV contract* below; the answer is
-> **3 × 180,224**, not 3 × 262,144.

-The KV contract is Frank's: **K unquantized (f16), V `q8_0`** —
-`--cache-type-k f16 --cache-type-v q8_0`. Two hard dependencies ride on it:
+The KV contract is Frank's, as of 2026-10-03: **both K and V unquantized
+(f16)** — `--cache-type-k f16 --cache-type-v f16`. The asymmetric contract it
+replaced (f16 K + `q8_0` V) had existed to make three slots fit; with two
+slots the exact-value budget opens, and 4 KiB/token × 8 layers × 2 of extra
+V traffic is the measured ~2 % decode tax. The serve script still passes both
+flags explicitly — the asymmetric-era law that a quantized V requires
+`--flash-attn on` stays pinned by the seam.
 
-- **`--flash-attn on` is mandatory**: quantized V exists only on the FA path.
-  Without the flag the engine falls back silently and the contract becomes a
-  lie. The serve script pins the trio; the bats seam pins the script.
-- The VRAM budget: attention KV lives in the 8 full-attention layers only
-  (4 KV heads × 256 dim). K f16 ≈ 16 KiB/token, V q8_0 ≈ 8.5 KiB/token
-  (34 B per 32-element block) ⇒ ~24.5 KiB/token over the pool.

-**The pool size came from two boots, not from a formula.** `free`-style

-The two rows price the projector and its image buffers at **~1.4 GiB** — not
-the ~0.9 GiB the 918 MB file suggests, because the vision encoder's own
-activation and compute buffers ride along. Solving the second row's non-KV cost
-against Frank's 2–3 GiB band: the card is 24,576 MiB, so
-`KV ≤ 24,576 − 9,216 − 2,048 = 13,312 MiB` ⇒ pool ≤ 556,630 tokens, rounded
-down to a multiple of 3 × 4,096 ⇒ **540,672**, i.e. 13,265 MiB of KV and
-**2,441 MiB free** (measured, 21,684 MiB used).
+The 32 KiB/token full-attention KV price (8 layers × 4 KV heads × 256 dim ×
+2 B × 2 halves) prices the deployed pool at 401,408 × 32 KiB = **12,544 MiB
+of KV**; the card is 24,576 MiB, so the shape leaves **4,046 MiB free**
+(measured steady-state — the KV pool is allocated whole at boot, so this is
+the ceiling). The headroom above the 2–3 GiB floor is deliberate slack, not
+an invitation: another 32,768 tokens of pool (1 GiB) would trade the last
+safety margin for window the harness compacts before reaching anyway.
 
-**Why 3 × 262,144 was never possible.** Three native windows are 786,432
-tokens = 18.4 GiB of KV *alone*; plus the 8.86 GiB of non-KV cost that is
-27.3 GiB on a 24 GiB card. The quant step bought 0.86 GiB; the geometry needed
-6 GiB.
+**Why 2 × 262,144 with f16 V does not fit either.** The native window pair is
+524,288 tokens = 16,384 MiB of KV plus ~7,986 non-KV = 24.4 GiB: under the

+The per-slot window is the whole price, in both directions:
 
-The per-slot window is the whole price. Two consequences the fleet depends on:
-
-- **A prompt over 180,224 tokens is a hard 400**, so `~/.omp/agent/models.yml`
-  sets `contextWindow: 180224` for this endpoint — the harness compacts before
+- **A prompt over 200,704 tokens is a hard 400**, so `~/.omp/agent/models.yml`
+  sets `contextWindow: 200704` for this endpoint — the harness compacts before
   it reaches the ceiling instead of discovering it.
-- **frank-primary's compaction prompt no longer fits with room to answer.**
-  Its trigger is 183,501 tokens — already above this slot — and its summary
-  budget is 32,768 output tokens. On the two-slot shape (262,144) that left
-  32.8k of output room, which is why that number was chosen; on this shape a
-  single compaction request must be truncated or split. Nothing in the fleet
-  routes compaction here automatically, but any runbook that claims frank-small
-  "fits a compaction request in ONE request" is describing the 262,144 shape.
+- **frank-large's tallest pre-compaction prompt now fits here.** Compaction
+  for frank-large sessions runs on this endpoint (`compactionModel` in
+  `models.yml`); frank-large compacts at 70 % of 262,144 = 183,501 tokens,
+  which did **not** fit the old 180,224 slot and fits 200,704 with 17,163
+  tokens to spare. The 2026-10-02 window trim had restored the fit for
+  frank-primary's smaller 140,492-token trigger; the 2026-10-03 reslice widens
+  the fit to frank-large itself. Nothing routes compaction automatically —
+  the point is the ceiling no longer forbids it.
+- Two simultaneous generations are the slot ceiling; a third request queues
+  behind a released slot (the mechanism measured on the 3-slot shape).

+landed **21,276 MiB used / 2,849 MiB true free** — non-KV measured 8,732 MiB,
+inside the 2–3 GiB floor, so the pool stayed at 401,408 and the
+12,288-token step-down ladder was never climbed. Quote `nvidia-smi`'s `free`
+field, never `total − used`: the driver holds ~450 MiB of reserve the
+subtraction hides (that error once overstated this card's slack by a
+half-GiB).
+
+**Quant ceiling, evaluated and closed 2026-10-03 (Frank: stay here).**
+`Q8_0` is the only rung above this one on the Hub (9,545,979,424 B = 9,104
+MiB, +1,671 over Q6_K): at the live pool it would leave 1,178 MiB free —
+under the floor — and the calibrated bandwidth law (it predicted this file's
+94.4 t/s from Q5_K_M's 104.84 within 1 %) puts decode at ~72 t/s, a further
+−24 % for the near-lossless rung. Fitting it was priced two ways (trim the
+pool to 2 × 182,272 — which also breaks frank-large's 183,501-token
+compaction-prompt fit by 1,236 tokens — or revert V to `q8_0`), and both
+were declined. Re-open only on evidence the Q6_K residual matters.
+
+**Pool prices on this card come from boots, never formulas** — the measured
+boot-pair table lives in [[frank-small-llama-mimo-q5km]] (*Shape and KV
+contract*) and still prices every rollback shape.

+`BATCH_SIZE=4096 UBATCH_SIZE=2048` — both doubled from 2048/1024, and the trade
+measured rather than assumed, because the predecessor shape recorded **"ubatch
+2048 failed the scratch boot"** and this card has less free space than it did.
+
+**That failure was a different shape, and it did not reproduce here.** The
+service itself is the bench (one card holds one server, so no scratch port):
+the old rung was re-booted through a transient `FRANK_SMALL_ENV_FILE` drop-in
+and reproduced the 2026-10-03 boot **byte-identically** — 21,276 MiB used /
+2,849 MiB free — which makes the ubatch the only variable in the comparison.

+  [[frank-small-llama-mimo-q5km]] is the other way to buy room back.
+
+**Why 2048 is right HERE while 512 was right on the R9700 sibling: the curve is
+backend-specific.** The 2× R9700 layer split peaks at ubatch 512 and is 10 %
+off that peak by 2048 ([[frank-medium-batch-ubatch]]); on this CUDA card the
+curve climbs monotonically to 2048 (710 → 1,188 t/s on the 35B MoE sweep,
+1,944 → 2,423 t/s on the Ornith 8k sweep, both with decode flat). Never carry a
+ubatch verdict across backends.
+
+The logical `--batch-size` is VRAM- and throughput-neutral — two sweeps and this
+A/B agree — so 4096 costs nothing and buys nothing by itself; it is here because
+that is the pair the curve was measured at.
+

+|VRAM|**21,276 MiB used / 2,849 MiB free** of 24,576 (`nvidia-smi` `free`, steady state) — inside the 2–3 GiB floor with exact V AND the higher rung. Superseded 2026-10-05 by the batch doubling: **21,846 / 2,279** — see *Compute-buffer geometry*|
+|Decode, temp 0, no thinking|**94.44 tok/s** on the identical 506-token probe that measured 104.84 on Q5_K_M — **−10 %**. Decode on this card is weight-bandwidth-bound, and Q6_K streams ~10 % more bytes per token; the quant rung buys quality with decode rate, measurably|

+## Client contract
+
+llama.cpp surface, live-verified on this model family: model id `frank-small`,
+native tools via `--jinja` (`tool_calls` in the response), thinking in
+**`reasoning_content`**, vision via `image_url` content parts. Two vision
+traps, both measured here:
+
+1. A top-level `images` field on `/v1/chat/completions` is silently ignored
+   and the model invents a color.
+2. **The probe image must be big enough to supply real image tokens.** A
+   10×10 px solid-red PNG came back "The image is a video, so I can't see its
+   content" — the engine itself warns at boot that Qwen-VL wants ≥ 1024 image
+   tokens, and a postage-stamp image lands one patch below usable signal.
+   512×512 answers `Red` in 19 tokens. Always probe vision with a ≥ 256 px
+   image; a wrong-color answer from a tiny image is the probe's fault, not
+   the endpoint's.
+
+`~/.omp/agent/models.yml` sets `contextWindow: 200704` — the PER-SLOT window,
+so the harness compacts before llama.cpp answers a longer prompt with a 400.

+
+# vLLM Boot Forensics and Config Interrogation
+
+For serve-script vLLM endpoints (frank-primary/qwen-fp8 on dankserver, any
+`podman rm -f` + restart service).
+
+## 1. Capture the true cause — the journal, not `podman logs`
+
+The serve script runs `podman rm -f <container>` at every start, so a dead
+container's log is GONE by the time you look; `no container with name or ID`
+means the journal is the only source. The engine's stdout survives in
+journald under the container tag:
+
+```bash
+journalctl --no-pager --since "20 min ago" | grep -a "<container>\[" | tail -40
+journalctl --no-pager --since "8 min ago" | grep -a "<container>\[" \
+  | grep -aiE "error|exception|assert|raise|invalid|failed" | grep -av APIServer | tail -12
+```
+
+Why naive greps fail:
+
+- Default format truncates lines at the display cut, and the fork's giant
+  single-line ERROR dumps are journald-SPLIT — the decisive sentence never
+  appears in short format.
+- `-o cat` strips the `svc[pid]:` prefix, so grepping the tag against `-o
+  cat` returns nothing — use the default format for the tag, `-o json` for
+  the content.
+- Time filters: relative (`--since "NN min ago"`) only — absolute timestamps
+  are local PDT while the engine logs UTC; never mix.
+
+**The JSON decode procedure** (proven 2026-10-01, caught
+`torch.OutOfMemoryError` exactly):
+
+1. Bound the window: last traceback lines + the `container died` podman
+   event.
+2. `journalctl --no-pager --since … --until … -o json | python3 -c …` on the
+   remote: handle `MESSAGE` possibly arriving as a **byte list**
+   (`bytes(int(x) for x in m).decode("utf-8","replace")`), strip ANSI
+   (`re.sub(r"\x1b\[[0-9;]*m", "", m)`), dedupe by first ~12 chars (one
+   logical traceback can arrive as 20+ entries).
+3. Reassemble the worker traceback: filter skeleton lines
+   (`File |…| raise |^+|~+|…<N> lines|…|re-`), keep content lines. The
+   decisive line is usually the last content line.
+4. **The diagnosis is the gap math: `ask − free = shortfall`.**
+
+**The wrapper trap:** `RuntimeError: Engine core initialization failed. See
+root cause above` is the WRAPPER — the real cause is the EngineCore traceback
+above it, ending in `RuntimeError: Worker failed with error '<cause>'`. Grep
+for `Worker failed with error`.
+
+**For probe boots / runner scripts:** capture live BEFORE teardown —
+`podman logs -f <ctr> > /home/dank/logs/<arm>.engine.log 2>&1 &` right after
+launch. A runner's `podman rm` destroys the only copy; two 2026-10-01
+failures had their root cause eaten this way, and an 8-line bootfail capture
+is insufficient.
+
+## 2. Failure classes
+
+| signature | class |
+|---|---|
+| `CUDA out of memory. Tried to allocate X GiB … Y GiB free` | capacity; the gap math names the next rung ([[RDNA4 MoE Expert Offload VRAM Budget]]) |
+| `Worker failed with error 'Constraints violated (L['query_start_loc'].size()[0])! … specialized it to a constant (N)'` | torch.compile/dynamo shape specialization (N = num_seqs+1-ish) — NOT memory |
+| `Deactivated successfully` with no traceback | container exited CLEAN (vLLM API server exits 0 after an EngineCore fatal); container already removed — re-read the journal, check `NRestarts` |
+| `no container with name or ID` | container rm'd; journal only |
+
+Boot-order reality: the plan computes fine at impossible budgets; the
+failure lands later in worker init, not at plan time. A plan line printing a
+huge arena does NOT mean it will boot.
+
+Bypasses this fork exposes for compile faults: `--enforce-eager` (skips
+torch.compile AND CUDA graphs — drops graphs, a real cost),
+`VLLM_DISABLE_COMPILE_CACHE=1`, `VLLM_USE_AOT_COMPILE=1`. A stale cache is
+usually NOT the cause — verify before "fixing" it (`~/.cache/vllm` may hold
+only `modelinfos`; each `podman run` gets a fresh container FS unless the
+cache dir is mounted).
+
+**Crash-loop signature (shape does not fit):** `Started … ~6.7 min later …
+Deactivated successfully … restart`. Diagnose with `systemctl show -p
+NRestarts` + per-attempt duration. `Restart=always` loops visibly;
+`Restart=on-failure` stays SILENTLY DEAD (`podman wait` returned 0, systemd
+saw a clean exit).
+
+## 3. Observation hygiene during recovery
+
+- A container being STOPPED still answers `podman logs`, so a watcher
+  grepping its log reports PRE-change values and looks like the fix failed.
+  Discriminate by container identity:
+  `podman ps --sort created -a --format '{{.ID}} {{.Status}} {{.CreatedAt}}'`
+  — require the container to post-date the arm start, then read only that ID.
+- A leftover probe script whose tail does `podman rm -f <prod-container>`
+  fires against a freshly DEPLOYED engine. Signature: a previously-healthy
+  unit exits 0 (`Started → Deactivated`, code 0) — an external rm, not a
+  crash. Suspect an external actor before debugging the engine; `pgrep -af`
+  every script you launched (and kill strays of `deploy-remote.sh` by
+  explicit PID — killing the dev-side deploy job does NOT kill its host-side
+  runner).
+
+## 4. Ops laws that bite during recovery
+
+- `Restart=always` does NOT fire after an explicit `systemctl stop` — a
+  deploy's stop leaves the unit down until something starts it. Check
+  `systemctl is-active` yourself.
+- `ExecStop=podman stop -t 120` requires `TimeoutStopSec` > 120; the 90 s
+  default kills the stop and logs `Failed with result 'timeout'`.
+- A `D`-state worker cannot be reaped by ANY signal (SIGTERM/KILL/`podman rm
+  -f` all fail). Check `ps -o pid,stat,etime,comm` before declaring a GPU
+  wedge — measured 2026-10-01: D → R on its own within ~3 min, then the
+  container stopped normally.
+- Never `pgrep -f`/`pkill -f` a pattern that appears in your own command
+  line — kill by explicit PID list.
+- `git stash -u` (not bare `git stash`) for deploy windows — untracked files
+  still trip the deployer's dirty-tree gate.
+- A production engine started by a transient/ladder unit is NOT
+  boot-persistent; pin the winning numbers in the repo and deploy the real
+  unit.
+
+## 5. Logging audit (what more can this container say?)
+
+Answer with evidence from the live image, not upstream docs:
+
+1. Enumerate the fork's own env registry:
+   `podman exec <ctr> python -c "import vllm.envs as e; print(chr(10).join(k for k in dir(e) if k.isupper() and any(s in k for s in ('LOG','DEBUG','TRACE','STATS','PROFILER','VERBOSE'))))"` — then read defaults/clamps in `vllm/envs.py` (e.g. `VLLM_LOG_STATS_INTERVAL` defaults 10.0 s, clamped ≥ 1.0; telemetry emits only while requests are in flight).
+2. **Find the REAL HIP/ROCm library paths before grepping for AMD env vars** —
+   containers often install ROCm into system dirs, not `/opt/rocm`
+   (`podman exec <ctr> sh -c 'find / -name "libamdhip64.so*"'`). A grep of
+   `/opt/rocm/lib` that finds nothing is a FALSE NEGATIVE, not an absence.
+   Then `strings <lib> | grep -E '^AMD_LOG_LEVEL$|^HSA_ENABLE_DEBUG$'`.
+3. Scan vendor kernel `.so`s for switches — and separate tuning vars from
+   logging vars (both share a prefix).
+4. **Measure the DEBUG payoff**: count `logger.debug` sites in the module of
+   interest. 0–10 sites ⇒ a per-module DEBUG bump buys almost nothing; global
+   `VLLM_LOGGING_LEVEL=DEBUG` additionally makes api_server log full
+   request/response bodies (incident window only).
+5. Check the deployed argv for `--disable-log-stats` / `--log-configs` to
+   know what is already suppressed.
+
+Report: lever / effect / cost table, split into permanent-safe (stats
+interval), incident-window (`AMD_LOG_LEVEL`, DEBUG), and does-not-exist
+(absent strings). Wire via env-gated `-e` pass-throughs so default-off
+preserves behavior.
+
+## 6. Interrogate a live endpoint's REAL config
+
+Flags and env diverge from intent constantly — rollbacks drop them silently.
+Read what the container is actually serving, then prove the client contract
+behaviorally:
+
+```bash
+# live argv (the truth)
+ssh host 'podman exec <ctr> bash -c "cat /proc/1/cmdline | tr \"\\0\" \" \"" | tr " " "\n" \
+  | grep -A1 -E "max-model-len|max-num-seqs|kv-cache|reasoning-parser|tool-call-parser|template-kwargs|utilization|speculative"'
+# container env knobs (fork tuning that never appears in argv)
+ssh host 'podman exec <ctr> bash -c "env | grep -E \"R4D_|CLAV_|VLLM_\" | sort"'
+# capacity contract as measured at boot
+ssh host 'podman logs --tail 3000 <ctr> 2>&1 | grep -aE "GPU KV cache size|Maximum concurrency|non-default args"'
+```
+
+`non-default args` lines print what the server overrode — the fast way to
+catch a flag that never landed. `GPU KV cache size: N tokens, Maximum
+concurrency for M tokens per request: X.XXx` is the capacity contract:
+N ≥ requests × M or the last client gets truncated.
+
+**Thinking contract:** a reasoning model on vLLM returns `reasoning` ONLY if
+the server runs a reasoning parser; without it the thinking lands INLINE in
+`content` with a dangling close-tag and a null `reasoning`. Verify with a
+temp-0 completion: pass = `reasoning` non-empty AND no `<\/think>` in
+`content`. Diagnose with `ReasoningParserManager.list_registered()`
+(import `vllm.reasoning`).
+
+**Tool contract:** `tool_choice: "auto"` on a server WITHOUT
+`--enable-auto-tool-choice` returns HTTP 400 — reads like a model fault, is a
+config gap. Probe with a real tool schema and check `tool_calls` +
+`finish_reason`.
+
+**Restoring a dropped contract from history:**
+
+```bash
+git log --all --oneline -S"reasoning-parser"
+git show <commit>:scripts/serve-<svc>.sh | grep -B3 -A3 "reasoning-parser"
+```
+
+Qwen3-family values that work on the tcclaviger fork: `--reasoning-parser
+qwen3`, `--enable-auto-tool-choice --tool-call-parser qwen3_xml`,
+`--default-chat-template-kwargs '{"enable_thinking": true,
+"preserve_thinking": true}'`. `preserve_thinking`/`enable_thinking` are
+chat-template variables, NOT engine flags: they belong in
+`--default-chat-template-kwargs` server-side or `chat_template_kwargs` in the
+request body; a bare top-level body field of that name is ignored. Check the
+payload's `tokenizer_config.json` carries the key before trusting it either
+way.
+
+`/health` 200 says the engine is up, not that the contract is on the flags
+you think — any client report of odd content (inline thinking, 400 on tools,
+clipping at depth) starts with sections 1–3 here before touching anything.

+# vLLM Porting and Compile Triage
+
+## Part I — Forward-porting a model architecture
+
+### 1. Check whether a port already exists; size the work honestly
+
+Read what the target image already ships before assuming a port is needed: a
+backport's upstream PR may be merged in the target version, and the target may
+carry a native kernel path the older line lacks (e.g. `rfi_hip` for RDNA4
+native quantized MoE). Porting around a native path that was already there is
+the expensive mistake.
+
+An upstream backport ships two kinds of file: **additive** (the new model
+package, its config, its kernel modules — port these) and **whole-file
+replacements of vLLM core** (`model_runner.py`, `scheduler.py`,
+`kv_cache_utils.py`, platform files — these are version X's copies of files
+version Y restructured; copying them is a DOWNGRADE, not a port). Measure both
+(`find … | xargs wc -l`), and say the additive-only ratio out loud before
+starting — one real case: a 71,724-line overlay reduced to 10,385 additive,
+and the "missing" drafter was already registered in the target.
+
+### 2. Enumerate the gap in ONE pass, not one ImportError at a time
+
+Inventory the target tree first (`model_executor/layers/`,
+`v1/attention/backends/`, quantization backends, spec-decode drafters in
+`registry.py`, `third_party/flash_linear_attention/ops/`). Then walk the
+staged package with `ast`, resolving every `from vllm… import X` against the
+target, split into MODULE-missing vs NAME-missing.
+
+- **The double-prefix bug:** the dotted module already starts with `vllm.`,
+  so joining onto the package dir needs
+  `rel = mod.split(".", 1)[1].replace(".", os.sep)`.
+- **Static scans over-report:** bare annotations, TypeAlias and star
+  re-exports resolve at runtime. Do a runtime check
+  (`importlib.import_module` + `getattr`) before quoting numbers — one scan
+  said 151/163 resolved; runtime said 10/13.
+- **Classify:** redirects dominate (version moved a symbol to a submodule) —
+  a ~60-line rewriter splitting `from X import (a, b, c)` blocks handles
+  them; **delete a block that empties** (a bare `from X import (` with an
+  empty body is a SyntaxError) and gate the rewriter on `ast.parse` of every
+  touched file.
+- **Port absent symbols with AST extraction**, not copy-paste: locate the
+  `ClassDef`, check every base/decorator resolves in the target, append the
+  exact segment, re-`ast.parse` the target, roll back on failure, skip if
+  already defined.
+
+### 3. Silent-default traps and transformers gates
+
+- Check every `cfg_int(cfg, key, DEFAULT)` against the new checkpoint: if the
+  key was renamed, the DEFAULT silently survives and the model computes fluent
+  nonsense with no error. Diff every config key the old parser reads against
+  the new `config.json`. When the old port used a fallback, the CHECKPOINT's
+  value must win (measured: `num_experts_per_token` fallback 7 vs
+  checkpoint `num_experts_per_tok=8`).
+- `model type X but Transformers does not recognize this architecture` =
+  pinned transformers predates the model. Upgrading transformers inside a
+  pinned vLLM image breaks things hard to attribute — prefer registering a
+  genuine `PretrainedConfig` subclass:
+  `CONFIG_MAPPING.register("glm5_next", Glm5NextConfig)`, gated by a real
+  round-trip (`AutoConfig.from_pretrained(<ckpt>)` returns the right class).
+  If the target image's transformers is below vLLM's declared minimum,
+  upgrading inside the image beats a shim.
+- **Hardware-gate flags from the port's own docs**: search the README for the
+  arch name and "do not" — e.g. a native quant MoE backend that is
+  CUDA/CDNA-gated falls back to per-call quantize-dequantize emulation at
+  ~5x slower; pin those flags in the serve script with a comment citing the
+  line.
+- **Backend selection:** default to `auto`, then READ the chosen-backend
+  line. `TRITON_UNFUSED` rejects some activation keys; `TRITON_ATTN` rejects
+  MLA + sparse attention — both surface as an init rejection. **"Using
+  'EMULATION' backend" is a FAILED configuration, not a success** (weights
+  dequantized per call: memory + throughput cost).
+- `Loading model from scratch…` for many minutes usually means the port
+  SUCCEEDED and you are in weight placement — verify all layers constructed,
+  both TP workers alive, zero errors, before chasing memory. And if it does
+  not fit, **prove the band is empty**: sweep the knob and show no setting
+  works; a single OOM is not a conclusion. Keep `MemAvailable` guarded
+  (abort on low RAM; do not let the OOM killer take co-tenants).
+
+### 4. Shims that must survive worker spawn
+
+vLLM v1 workers are spawned processes — a parent-process monkeypatch is gone
+by weight-load time. In order of preference:
+
+1. **Patch the installed library's source file on disk** (reliable). Locate
+   the real install path at runtime:
+   `python -c "import transformers,os;print(os.path.dirname(transformers.__file__))"`.
+2. `.pth` in site-packages — works but runs at interpreter start and can
+   import a package mid-import (circular import through `accelerate`);
+   expect failure.
+3. `sitecustomize.py` — often silently DEAD: Debian ships its own at
+   `/usr/lib/python3.12/sitecustomize.py`. Verify it is actually imported
+   before debugging why it has no effect. (A `.pth` on `PYTHONPATH` is never
+   executed by `site.py`; `sitecustomize.py` is.)
+
+Always confirm with a FRESH process — never with the process that set the
+patch up (`is_moe`, `num_experts_per_token`, `mhc_num_residual_streams`).
+
+**Misleading OOM names on ROCm:** `torch.AcceleratorError: CUDA error: out of
+memory` from `pin_memory()` is usually the HOST `memlock` rlimit, not VRAM.
+Cannot be raised from inside a container or root's own shell; only PAM at
+login: `/etc/security/limits.d/*.conf` + a NEW session. Confirm by pinning
+2/8/16 GiB — if those succeed, the rlimit was a real bug but is not the
+failure you are chasing.
+
+### 5. Ship as an idempotent patch-at-start applier
+
+One `apply.sh` at container start, each step guarded by a grep-for-marker
+(re-entry safe), ending in a verification block that imports every installed
+symbol and prints PASS/FAIL per symbol — ~10 s instead of a multi-minute
+load, and it turns "I think it works" into evidence.
+
+---
+
+## Part II — torch.compile / dynamo bring-up triage
+
+### The five laws (measured on torch 2.11+rocm, vLLM 0.29-dev)
+
+1. **`suppress_errors` does NOT cover graph breaks** — fullgraph=True +
+   suppress_errors=True still raises `Unsupported`. Only `fullgraph=False`
+   tolerates a break.
+2. **A warm `lru_cache` is not trace-safe** — dynamo re-traces the wrapped
+   body to build its guard even on a hit ("Dynamo ignores the cache wrapper
+   and directly traces the wrapped function"). Resolve the value ONCE into a
+   plain module global and read that; a global read folds, a cached call does
+   not. Verified in-image: warm lru_cache-calling function still fails
+   fullgraph=True; a plain global read compiles.
+3. **AOT compile refuses breaks outright** ("Graph breaks are not supported
+   with aot compile") — set `VLLM_USE_AOT_COMPILE=0` for a break-tolerant
+   run.
+4. **Fatal vs tolerated breaks:** tolerated breaks get a resume function
+   (untraceable part runs eagerly, numerics unchanged). Fatal ones cannot:
+   `Unsupported: Read uninitialized cell` (a traced callee closes over a name
+   bound after its definition) and `Skip calling torch.compiler.disable()'d
+   function` under fullgraph=True. `torch.compiler.disable` is the documented
+   escape hatch for host-side/stateful work (ContextVar reads, lazy
+   allocation, workspace grab) and is a NO-OP when nothing compiles — safe to
+   ship in the stock path.
+5. **Trust the frame chain, not the line number** — dynamo INLINES user
+   callees; an inlined failure reports the enclosing function's `def` line.
+   "KeyError in forward at the def line" is really "a callee raised".
+   `TORCHDYNAMO_VERBOSE=1` adds nothing for a plain Python exception (only
+   for dynamo-internal errors).
+
+**The tell** that the trunk lacks compile support at all:
+
+```
+Cudagraph mode FULL_AND_PIECEWISE requires piecewise capture, but the loaded model
+provides neither a compiled submodule nor breakable CUDA graphs. Overriding to
+FULL_DECODE_ONLY.
+```
+
+Diff against the family that DOES compile and copy its
+`@support_torch_compile` decorator including `dynamic_arg_dims` and any
+`enable_if` hook; env-gate every change so the file can stay mounted for an A/B.
+
+### Procedure
+
+0. **Establish what configuration is ACTUALLY in effect**:
+   `podman exec <ctr> printenv VLLM_COMPILE_FULLGRAPH VLLM_USE_AOT_COMPILE …`.
+   A launcher that "sets" an env var in a branch may silently drop it — four
+   consecutive boots ran `fullgraph=True` while the operator believed
+   otherwise, which makes the reported failure MOVE as breaks are removed and
+   invites entirely wrong theories.
+1. **Boot with the break list, not the first error:** `TORCH_LOGS=graph_breaks`
+   + `VLLM_USE_AOT_COMPILE=0` + `VLLM_COMPILE_FULLGRAPH=0`. Re-verify each
+   candidate break under the flag-free config you actually intend — a break
+   that appears only under the logging flag is a diagnostic artifact.
+2. **Fix in priority order:** (a) host syncs in the traced region
+   (`.item()`/`.cpu()`/`.tolist()` — check reachability first, a dead fallback
+   branch is not your blocker); (b) capability probes doing I/O in `forward`
+   (`os.path.exists`, `.so`/`ctypes` lookups — resolve once into globals,
+   warm at import); (c) lazy stateful work (hoist, or `torch.compiler.disable`
+   a thin wrapper); (d) new kernel specializations — check the vendor ships
+   SOURCES (`nm -D`/`strings`): a binary-only templated `kernel<128|256|512>`
+   makes the 288 you need unreachable. Fix at the PATTERN level (one
+   launcher/decorator family breaking all 39 call sites), not site level.
+3. **KeyError on a bare module name** = dynamo's name→object map miss
+   (`OutputGraph.nn_modules`: registered `output_graph.py:1259`/`:1384`,
+   read back `:3000`, `_buffers/_parameters/_modules` stripped at `:1225`).
+   Ship a probe via `sitecustomize.py` that patches
+   `OutputGraph.example_value_from_input_node` and keeps weakrefs of live
+   graphs, printing `node.target`, key count, near-miss keys — separates a
+   cross-graph reference from a name-derivation mismatch.
+4. **Instrumenting a startup hook is a FIREARM — arm it once:**
+
+   ```python
+   if os.environ.get("PROBE_ARMED") == "1":
+       pass                     # an ancestor already armed it -> stay inert
+   else:
+       os.environ["PROBE_ARMED"] = "1"
+       ...install probes...
+   ```
+
+   A `sitecustomize.py` on `PYTHONPATH` imports in EVERY interpreter and
+   children inherit `PYTHONPATH`: an unguarded hook that imports the engine
+   self-replicates (observed: 19+ levels, 33 processes alive 18 min later).
+   Kill the chain by removing the container whose cgroup owns every
+   generation, then verify with a precise `/proc/<pid>/environ` count —
+   NEVER pattern-kill an interpreter name on a host running python in
+   production containers. Also chain the image's own sitecustomize so its
+   hook survives.
+5. **Cheap in-image classification (no boot):**
+   `g = torch.compile(fn, backend="eager", fullgraph=True)` inside the
+   container (with `--device /dev/kfd --device /dev/dri` — torch.compile
+   queries a device even on the eager backend). ~5 s per question instead of
+   ~7 min boots.
+6. **Package as real patch artifacts:** hand-written `@@` headers are not
+   diffs and `patch(1)` rejects them. Generate
+   `diff -u --label a/<path> --label b/<path> orig new > name.patch` with
+   `--- a/` / `+++ b/` paths so `-p1` works; verify by applying to a fresh
+   extraction of the pinned image and comparing sha256 (`sha256sum` must
+   equal the `b/` hash recorded in the header). Header carries: STATUS, the
+   measured evidence, base+patched sha256, how to apply, the NEXT blocker.
+
+### Cost model before investing
+
+**Profile first** — parse the rank0 chrome trace (`POST /start_profile`,
+device-activity rows) for the kernel table. Measured case: the long-suspected
+expert-gather was **1.05 %** of device time while **44 %** was unfused
+pointwise glue (708,500 `vectorized_elementwise_kernel` launches =
+1,428/token) — a months-old "structural" conclusion died in one afternoon.
+Speculative decoding does NOT help a shape whose per-token cost scales with
+the token count, and it hurts prefill. Decide the ceiling up front: if the
+fused target is ~13–15 tok/s, do not spend a night of boots chasing 35.
+
+---
+
+## Part III — EAGLE3 / DFlash2 / DSpark aux-hidden-state protocol port
+
+Goal: make a trunk satisfy `SupportsEagle3` so a DFlash2 drafter
+(`DFlash2DraftModel`, method `dflash`) boots. Built on the GLM-5.3-Flash port
+(tcclaviger fork, 2026-09-30; four failed boots produced the laws below).
+
+### The four laws
+
+1. **Patch the instance the runner calls.**
+   `set_eagle3_aux_hidden_state_layers(self.model)` (model_runner.py, right
+   after `model_loader.load_model`) runs on the LOADED instance — for a
+   multimodal model that is the `…ForConditionalGeneration` WRAPPER (the
+   APIServer log line `Resolved architecture: …` names it), NOT the text
+   model it holds as `self.language_model`. Patching only the inner
+   `…ForCausalLM` reproduces the identical `RuntimeError: Model does not
+   support EAGLE3 interface` forever. Patch BOTH wrappers.
+2. **The check is Protocol isinstance, NOT duck typing.**
+   `supports_eagle3(model)` = `isinstance(model, SupportsEagle3)`
+   (interfaces.py ~1728; caller `v1/worker/gpu/spec_decode/eagle/eagle3_utils.py:20`).
+   `SupportsEagle3` is `@runtime_checkable` over base `SupportsEagleBase`
+   (`:1486`, `:1659`); `typing._ProtocolMeta.__instancecheck__` does
+   `getattr_static` over ALL `__protocol_attrs__` — including BASE-protocol
+   members — and breaks on the FIRST miss. Full member set:
+   `supports_eagle3`, `has_own_lm_head`, `has_own_embed_tokens`,
+   `set_aux_hidden_state_layers`,
+   `get_eagle3_default_aux_hidden_state_layers`. **Class attributes count as
+   presence; a methods-only implementation FAILS** because the three attrs
+   are missing. Verified in-image with stock typing, no boot: flag-only →
+   False; flag + two base members → True.
+3. **MRO forbids inheriting the Protocol.** Appending `SupportsEagle3` to a
+   wrapper already carrying Protocol-derived bases dies at class creation:
+   `Cannot create a consistent method resolution order (MRO) for bases …` —
+   MRO simulation (stub Protocols + `type("C", bases, {})`) confirmed no
+   position works. This failure also PROVES the isinstance-semantics question
+   is moot: class creation precedes any check.
+4. **Write the two methods by hand** — without inheritance the Protocol
+   defaults do not exist. Text model: unwrap to the trunk
+   (`self.model.aux_hidden_state_layers = layers`); multimodal wrapper:
+   delegate to `self.language_model` (the pixtral.py:498 pattern).
+   `get_eagle3_default_aux_hidden_state_layers` returns `(2, L//2, L-3)`; the
+   drafter config's `target_layer_ids` wins when present (GLM DFlash2 ships
+   `[5, 14, 24, 33, 42]` of 45).
+
+The fix shape (on EACH wrapper class):
+
+```python
+supports_eagle3: ClassVar[Literal[True]] = True
+has_own_lm_head: bool = False          # False when embed/lm_head are delegated
+has_own_embed_tokens: bool = False
+def set_aux_hidden_state_layers(self, layers): ...
+def get_eagle3_default_aux_hidden_state_layers(self): ...
+```
+
+### Trunk mechanics
+
+The trunk (`Glm5NextModel`) must be `EagleModelMixin`; add
+`aux_hidden_state_layers: set[int]` (default empty) + `start_layer` handling.
+Capture aux states in the layer loop: the state ENTERING each requested
+layer, BEFORE its input norm (GLM's loop carries the single-stream state;
+deepseek_v2's equivalent is `hidden_states + residual`).
+`use_aux_hidden_state_outputs=True` is set in model_runner.py (~:287) for
+methods `dflash`, `dspark`, `extract_hidden_states`; the forward returns
+`(hidden_states, aux_hidden_states)` conditionally after `self.norm` (tuple
+consumed at `v1/worker/gpu/cudagraph_utils.py:621`).
+
+### Window discipline and verification
+
+- Scratch boots on dankserver MUST stop + runtime-mask production
+  `frank-primary` first — the expert-offload planner reads `MemAvailable` at
+  plan time, and beside-prod boots die at plan with
+  `ExpertPlanError: host holds N of M swappable experts`. After stop+mask,
+  loop until `MemAvailable ≥ 230 GiB` before launching (a stop against a
+  mid-load engine SIGKILLs at ~90 s and the freed ~170 GiB takes >1 min to
+  return — a new window started during restore inherits the false failure).
+- Never launch a window while the previous window's RESTORE is in flight
+  (`systemctl start` returns immediately; the engine loads ~6 min).
+- Save full probe logs BEFORE teardown (`podman logs <probe> > full.log`);
+  decision greps truncate lines at `…` and tracebacks die with the container.
+- Cheap verification, no boot: AST-parse the patched file for class bases +
+  member presence; MRO simulation with stub Protocols; in-image `typing`
+  replication of the isinstance walk (pure stdlib — importing vllm itself
+  crashes on GPU-less inspection). Boot check: the worker line `Using Eagle3
+  auxiliary layers from config: (…)` = gate cleared.
+- Honest expectations: a target-side DFlash2/EAGLE3 port on a
+  pointwise-glue-bound trunk (~44 % of kernel time) buys ~ZERO decode gain —
+  the verification pass costs ∝ its token count. Port it for capability, not
+  speed.

+- **e2e: the FrankBook-Pro leg scoped to its own trigger-gated Playwright
+  project.** The `11-admin` walk included the six `*arr`/qBittorrent admin
+  links that terminate on 192.168.0.112, so every deploy gate died there when
+  the Mac mini slept (Caddy 502 on the five vhosts, connection timeout on the
+  raw Sonarr link). Split: those links moved to
+  `tests/e2e/specs/19-frankbook.spec.ts` under a `frankbook` project;
+  `tests/e2e/run.sh` excludes it from the default project set, and
+  `scripts/deploy.sh` computes a trigger from the same BASE..HEAD range the
+  plan uses (the spec, `frankbook-pro/**`, `shared/homepage/services.json`,
+  the `dankclaw/Caddyfile` arr vhosts) and sets `E2E_INCLUDE_FRANKBOOK=1`.
+  Verified live with the host asleep: full suite 33/33 in 1.1 min, the admin
+  walk back to 5.4 s; `--project=frankbook --list` proves the selection.
+  Live pass of the frankbook walk itself is deferred to the next deploy with
+  an awake host.
+  - **Catch while verifying: the 17:47 Ornith-1.5-9B swap (`77decb5`) had
+    left `frank_small_unit.bats` and the deployer's payload gate stale** —
+    the seam still expected MiMo-Q6K names and `deploy-remote.sh` gated
+    `LLM_SMALL_MODEL_FILE`/`LLM_SMALL_MMPROJ` on files the unit no longer
+    loads (the anti-drift seam doing its job). Both repointed to the
+    Ornith-Q8 paths; full `./tests/run.sh` back to green (366 tests).
+- **frank-small: compute-buffer pair doubled to 4096/2048, and the prefill win
+  measured rather than assumed.** Frank asked for the batch and ubatch doubled.
+  The blocker was on record: the Q5_K_M predecessor documented **"ubatch 2048
+  failed the scratch boot"**, and this shape carries 616 MiB less free space
+  than that predecessor did.
+  - The A/B used the service itself as the bench (one card, one server — no
+    scratch port): the old rung was re-booted through a transient
+    `FRANK_SMALL_ENV_FILE` systemd drop-in, and it reproduced the 2026-10-03
+    boot **byte-identically** (21,276 used / 2,849 free), which is what makes
+    ubatch the only variable. Repo never saw a fake revert commit; scaffolding
+    staged to `~/.AGENTTRASH/20261005-frank-small-ubatch-ab/`.
+  - **At 8,928 prompt tokens: prefill 3,972/4,077 -> 4,207/4,212 t/s, +4.6 %,
+    for 616 MiB (free 2,849 -> 2,279).** Decode flat (91.9–93.0 vs 93.8–94.3 —
+    noise). The control that proves it is geometry and not drift: a 279-token
+    prompt sits below *both* micro-batches, so it cannot see the knob, and it
+    did not move (2,676 vs 2,658–2,811).
+  - **The predecessor's boot failure did not reproduce** — that was a shape
+    observation, not a law; this shape boots 2048 clean. And the fleet lesson
+    "**`--ubatch-size` has an optimum**" is now scoped to what it actually is:
+    true on the 2x R9700 layer split (peak 512, −10 % by 2048), false on the
+    CUDA 3090 where the curve climbs monotonically to 2048. AGENTS.md corrected
+    — the curve is backend-specific and must never be carried across backends.
+  - The seam stopped hard-coding a rung: `serve_argv` now carries `BATCH_SIZE`
+    and `UBATCH_SIZE` the way it already carried `CTX_SIZE`, and the pair test
+    asserts the argv follows the shipped env plus the `ubatch <= batch`
+    invariant. Proven live both ways — retuning the env to 8192/4096 keeps it
+    green, inverting to 2048/4096 turns it red. (The old assertions only ever
+    exercised the serve-script *defaults*, because the test env never carried
+    these two keys.)
+  - `4096/1536` is the documented middle rung; 2,279 MiB free sits at the bottom
+    edge of the 2–3 GiB floor. Deployed `e5893dc`, e2e gate PASSED (2 mini specs
+    flaky-then-passed once the sleeping FrankBook-Pro woke mid-run — WoL took a
+    second burst and ~90 s). Docs:

+- **frank-primary: shape F then shape G — MNBT 2048, the CUDA-graph plan term
+  pinned to the measured capture, KV forced to 400,700 tokens, and UTIL 1.0
+  proven UNBOOTABLE.** Frank asked what the batch was with GPUs showing open
+  space; the audit found the arena is `budget - non-expert - KV reserve -
+  graphs - overhead` where the only deploy-reachable terms are the budget and
+  the graph estimate (registry KV price 9,190 B/token and the 5.25 GiB
+  overhead are image constants; the ~3.5 GiB of driver-free VRAM was
+  estimator slack, not allocatable).
+  - Shape F (c682c63): MNBT 1024 -> 2048 (arena-free — the registry prices
+    overhead flat up to its nbt 4096 anchor and the fitted 5.25 was fitted AT
+    4096), util 0.98 -> 0.982, graph term 0.55 -> 0.32 GiB (256 base +
+    12/graph vs the fork's 256 + 52/graph). Measured: arena 17.52 GiB /
+    7,653 slots, budget 31.29.
+  - Shape G v1 (0a4ff30) tried util 1.0: **both workers refused init before a
+    single weight loaded** — `ValueError: Free memory on device cuda:N
+    (31.29/31.86 GiB ...)`, NRestarts=2 crash loop, zero payload progress.
+    The CLI field is `Field(gt=0, le=1)`, but the worker demands free >
+    budget, so budget == total is a trap, not a knife-edge. Frank: ".982 is
+    the law, never 1.00" — now with a second proof.
+  - Shape G v2 (c67a2ae, deployed green incl. e2e 33/33): util back to
+    0.982, graph base to 0 (the shape F boot reported a NEGATIVE -0.06 GiB
+    capture delta, so the 256 MiB base was fiction; 0 + 12 MiB/graph still
+    prices a future 18-graph spec-decode shape at 0.21 GiB), KV_BYTES
+    3.15e9 -> 3.1665e9 = Frank's 400,700-token ask.
+  - MEASURED live: arena **17.77 GiB / 7,762 slots** (+240 over shape E),
+    KV **401,408 tokens / 2.00x concurrency** — the first shape holding two
+    full-length conversations with real spare; capture measured 0.31/0.10
+    GiB against the 0.07 charge (under-charged, boots and holds); driver
+    used 30.97 of 31.86 GiB -> **0.89 GiB real free per card**, held through
+    a live 4,096-token generation (~38-39 tok/s single-request wall-incl.,
+    +13% vs the 33.99 shape-E baseline; single sample, not a bench).
+  - Verification seam rewritten to assert the shape by its OUTPUTS (util at
+    the 0.982 law, graph charge below the analytic default and per-graph
+    positive, KV pool >= 400,700 tokens at the measured 7,892 B/token).

+
+Frank's order: shrink frank-primary to a 200704-token window with about two
+resident full-length contexts, cut the KV pool, and drop MNBT to 1024. The
+first attempt (`30904ba`, 2 x 200704 + SEQS=2) **crash-looped**; the revert
+went live as `e460bbb`, and the shape was then re-applied one law at a time on
+top of the proven-good base, root cause first.
+
+- **ROOT CAUSE: `--max-num-seqs 2` cannot compile this model. It was never OOM,
+  never MNBT, never the KV dtype.** Four single-variable boot probes against
+  the then-deployed shape (production stopped for each, candidate booted AS the
+  service):
+
+  | MAXLEN | SEQS | MNBT | result |
+  |---|---|---|---|
+  | 262144 | 2 | 1024 | **Engine core initialization failed** |
+  | 262144 | 2 | 2048 | **Engine core initialization failed** |
+  | 262144 | 3 | 1024 | healthy - 792,069 tokens, 3.02x, arena 6,248 |
+  | 262144 | 3 | 2048 | healthy - the then-deployed incumbent |
+
+  `torch.fx.experimental.symbolic_shapes.ConstraintViolationError: Constraints
+  violated (L['query_start_loc'].size()[0]) ... specialized it to be a constant
+  (3)`, raised from AOT `build_guards(strict_error=True)` during
+  `determine_available_memory -> profile_run -> _dummy_run`, ~7 min in.
+  `model_runner.py` sizes that input buffer `max_num_reqs + 1` and `_dummy_run`
+  sets `num_reqs = min(max_num_batched_tokens, max_num_reqs)`, so its width is
+  **SEQS + 1** for ANY `MNBT >= SEQS` - 3 at SEQS 2, 4 at SEQS 3, exactly the
+  constant in the message. MNBT only moves the compile RANGE ((1,1024) vs
+  (1,2048)), which is why the identical error appears at both rungs.
+  `--enforce-eager` bypasses the path but drops CUDA graphs. The 2026-10-01
+  bf16 2 x 262144 failure was this same error class; its message named "KV
+  dtype and SEQS" together and nobody bisected, so the dtype was blamed - it
+  was a red herring.
+- **THE ARENA LEVER IS `max_model_len`, NOT `--kv-cache-memory-bytes`.** The
+  planner sizes expert cache as `budget - non-expert - KV reserve - graphs -
+  overhead`, and the KV reserve is registry-priced at **9190 B/token x
+  max_model_len**, independent of the pool override:
+
+  | MAXLEN | KV reserve | arena |
+  |---|---|---|
+  | 262144 | 2.48 GiB | 14.30 GiB / **6,248 slots** |
+  | 200704 | 1.91 GiB | 14.87 GiB / **6,496 slots** |
+
+  d(reserve) 0.57 GiB = d(arena) 0.57 GiB = +248 slots. The 6.1e9 -> 3.15e9
+  pool cut (2.75 GiB/rank) bought **zero** arena slots. The previous session's
+  premise - "the pool cut becomes arena, ~7,500 slots" - was wrong; the pool
+  cut is a runtime-HEADROOM lever (the shape it replaced died with `0 bytes
+  free` on a real 995-token request).
+- **Final shape (option D):** `--max-model-len 200704` x 3 slots, fp8 KV,
+  `--kv-cache-memory-bytes 3,150,000,000`/rank, MNBT 1024, gather 32x64, no
+  speculative decode, prefetch off, no `--expert-precise-memory`. The argv
+  keeps the only slot count that compiles; the POOL caps resident
+  conversations. Deployed `c769ff2`, healthy in 558 s, e2e 33/33.
+- **Measured live, and one prediction corrected.** `expert cache space 14.87
+  GiB / 6,496 slots` - the arena prediction landed exactly. But `GPU KV cache
+  size: 398,658 tokens, Maximum concurrency for 200,704 tokens per request:
+  1.99x` (3,146,129,408 B reserved), not the 2.04x the arithmetic predicted:
+  **the per-token KV price is shape-dependent** - 7,701 B/token at MAXLEN
+  262144 (6,100,000,000 B -> 792,069 tokens) vs **7,892** at 200704, ~2.5 %
+  dearer. Never extrapolate a concurrency figure across geometries.
+- **Smoke-verified on the live endpoint:** three concurrent 67-token requests
+  answered in parallel (~4.1 s each) - the 3 slots are real; native `tool_calls`
+  (`get_weather {"city":"Seattle"}`); thinking in `reasoning` with clean
+  `content`; `reasoning_effort` accepts only {xhigh, medium, low} and answers
+  400 for anything else (re-measured; the fork's message names the set).
+- **Harness contract followed the window:** `models.yml` `contextWindow`
+  262144 -> **200704** (compaction trigger 140,492 + 36,864 = 177,356 <=
+  200,704). Side effect: frank-primary's compaction request now fits inside a
+  frank-small slot again, which it had stopped doing when frank-small went to
+  3 x 180,224.
+- **Comment-only follow-up** `295d578` recorded the measured numbers and was

+## 2026-10-02 - plex: the readiness gate probed HTTP against a TLS-only service
+
+Found by accident, and it had been latent since the secure-connections posture
+was set: `deploy_plex` gated on `curl -fsS http://127.0.0.1:32400/identity`,
+which **cannot** succeed. PMS drops plain HTTP off-loopback - the probe's
+connection arrives on the container's eth0 - so Plex accepts the TCP connection
+and then answers with nothing, and curl reports "Empty reply from server" (52).
+
+- Trigger: a bare `./scripts/deploy.sh dankserver` (no `--service`) drains the
+  whole pending backlog, not just the service you were thinking about. plex's
+  per-service revision had been behind for long enough that this gate had never
+  run against the current posture. It burned its full 600 s and failed the run;
+  every service after plex in the order was left undeployed.
+- **Plex was healthy the entire time.** `https://127.0.0.1:32400/identity`
+  returned 200 with the MediaContainer XML in 44 ms while the gate was still
+  timing out. The in-container `http://127.0.0.1:32400/identity` also answers
+  200 - loopback is the one path PMS serves in the clear, which is exactly why
+  the host-side probe could not see the difference.
+- Evidence chain that settled it: `podman exec plex curl http://127.0.0.1:32400`
+  = 200; `curl http://127.0.0.1:32400` from the host = empty reply;
+  `/proc/net/tcp` inside the container showed `00000000:7E90` LISTEN plus stuck
+  ESTABLISHED pairs on `1703590A:7E90` (10.89.3.23, the container's own eth0
+  address) that never produced a response.
+- **The repo already knew this law, in a different file:**
+  `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. Fixed to `curl -fsSk --max-time 3 https://127.0.0.1:32400/identity`
+  (`-k`: PMS serves its own self-signed cert on 32400).
+- Re-deployed `39f0e0d`: plex recorded deployed, the *arr services recorded
+  (compose-recorded on this host, no restart attempted), tautulli deployed,
+  e2e 33/33. Verified after: `plex-https=200`, plex container up, tautulli
+  healthy, frank-primary untouched (`health=200`, NRestarts=0).
+- **Operating lesson: `deploy.sh <target>` with no `--service` is a fleet-wide
+  drain.** It restarts every service whose recorded revision is behind HEAD and
+  whose paths changed since. To touch one service, name it.

+Shape D left one question open — the plan's overhead term was reserving 2.35 GiB
+of compile headroom the boot never used — and the answer to Frank's free-VRAM
+question arrived together with a boot-cost bug that had been costing 181 s on
+every restart since the cutover.
+
+- **`--expert-precise-memory` is real and it fits (option A).** Boot-probed on
+  the shape-D base with production stopped, the candidate booted AS the service
+  (`FRANK_PRIMARY_ENV_FILE=/tmp/probe-b.env bash scripts/serve-frank-primary.sh`,
+  trap-guaranteed restore), the numbers read off the engine's own plan lines:
+
+  | plan line | shape D | shape E |
+  |---|---|---|
+  | `runtime overhead (non-torch + buffers + activation)` | 7.60 GiB | **5.25 GiB** (`precise (gfx1201 TP2 nbt4096/seqs16/len262144)`) |
+  | `expert cache space` | 14.87 GiB | **17.22 GiB** |
+  | slots | 6,496 | **7,522** (+1,026, +16 %) |
+  | `swap region` | — | 13.7 GiB / 5,986 slots, 133-134 per layer |
+  | boot | — | **healthy in 420 s**, no OOM |
+
+  The flag also prints `'expert_precise_memory': True` in `non-default args`, so
+  a silent argparse drop cannot hide. It was refused on 2026-10-01 only because
+  the 2 x 262144 bf16 shape was already 0.13 GiB under the ceiling — there the
+  flag was the last stack over the line, not the cause.
+- **The pool was NOT cut (option A) because the pool is not an arena lever.**
+  A 2.2e9 arm was probed in the same window and reports `277,686 tokens,
+  1.38x` — measured, rejected as the shipped value, kept as the conservative
+  fallback. With 3.15e9/rank the endpoint keeps shape D's 1.99x concurrency and
+  gains the arena, which is the shape D follow-up had actually been looking for.
+- **THE COMPILE CACHE WAS BEING THROWN AWAY ON EVERY RESTART — 181 s each.**
+  Measured: a fresh container has **no `/root/.cache` at all** (`No such file or
+  directory`); after our boot it holds `/root/.cache/vllm` at
+  **1,154,714,333 B in 4,665 files** plus `/root/.cache/comgr` at 229 MB, inside
+  the ephemeral layer, and `podman rm -f` (every deploy, restart, reboot)
+  discards them. The engine names the loss itself: `Compiling a graph for compile
+  range (1, 1024) takes 173.19 s` ... `torch.compile took 181.20 s in total` ...
+  `init engine (profile, create kv cache, warmup model) took 217.26 s
+  (compilation: 181.20 s)`. The serve script now mounts
+  `FRANK_PRIMARY_CACHE_DIR` at `/root/.cache` — the **parent**, so the vLLM
+  AOT/torch_compile tree (`VLLM_CACHE_ROOT`, default `/root/.cache/vllm`) and
+  the comgr JIT cache both persist, and nothing is hidden because the image has
+  no such directory. Same class of fix as the recipe's
+  `/cache/{triton,vllm,inductor}` volumes; the compile RANGE is part of the
+  cache key, so an MNBT change costs one recompilation, not a permanent tax.
+- **`GPU_MAX_HW_QUEUES=2`** (HSA hardware queues per GPU) added at Frank's
+  direction. Verified a real knob rather than a no-op — the literal is read from
+  `/opt/rocm/core-10.0/lib/libhsa-runtime64.so` — and shipped deliberately
+  alongside the 32x64 gather geometry. **Not A/B measured.**
+- **P2P: the hardware supports it, and the engine is already using it.** The
+  live log shows `r4d all-reduce INSTALLED (rank=0 max=49152KB finegrained=T…)`
+  on BOTH ranks and `Using ['R4D_AR', 'PYNCCL'] all-reduce backends` — R4D's
+  P2P path, with RCCL as fallback, measured at **45.274 GB/s bidirectional**.
+  Root ports `00:01.1`/`00:01.3` both report ACS `ReqRedir+`, so P2P hairpins at
+  the root complex; there is no XGMI. The old FAIL predates the 2026-09-20 board
+  swap. Kernel support confirmed: `CONFIG_HSA_AMD_P2P=y`, `CONFIG_PCI_P2PDMA=y`,
+  `CONFIG_HSA_AMD=y`, `CONFIG_ZONE_DEVICE=y`, `iommu=pt` on the cmdline.
+- **Recipe diff (Frank's 3 x R9700 compose vs this podman run), ranked:**
+  - *Acted on:* persistent compile caches (above — the one real operational
+    gap), and `GPU_MAX_HW_QUEUES`.
+  - *Retracted:* pinned `--compilation-config cudagraph_capture_sizes` was on my
+    list; measured, it is **not** a gap here — capture is 3 PIECEWISE + 2 FULL
+    graphs, `Graph capturing finished in 3 secs, took 0.31 GiB` (0.11 GiB on the
+    lighter rank). No 15-52-size ladder to cut.
+  - *Not acted on — measured candidates, none shipped (no bench window; these
+    are CPU-side and our decode is gather-bound, so a spin-wait stealing cores
+    from the gather threads is plausible but unproven):* `OMP_NUM_THREADS=8`
+    (defaults to all 16 logical CPUs on this 7700X), `HSA_ENABLE_INTERRUPT=1`,
+    `HSA_ENABLE_MWAITX=1`, `HSA_ENABLE_SDMA`, `HSA_NO_SCRATCH_RECLAIM`,
+    `HSA_ENABLE_IPC_MODE_LEGACY`. All six HSA names verified real — the literals
+    are read out of `/opt/rocm/core-10.0/lib/libhsa-runtime64.so` — so they are
+    knobs, not no-ops; any of them needs its own A/B before shipping.
+  - *Deliberate divergence, keep ours:* no MTP (the recipe has it; measured
+    fastest here), `qwen3_xml` vs `qwen3_coder` (ours verified live), no
+    `--override-generation-config` (server-side sampling defaults), published
+    port + Caddy rather than `network_mode: host`.
+  - *Non-gaps:* `shm_size 32gb` (ours is `--ipc=host`), `memlock -1` (same),
+    `SYS_PTRACE` (same), `/dev/kfd` + `/dev/dri` (same), `--enable-chunked-prefill`
+    (V1 default), `plecache` volume (the flag is not even passed), and
+    `ROCR_VISIBLE_DEVICES=1,2,3` vs our `HIP_VISIBLE_DEVICES=0,1` — verified
+    equivalent here: `rocm-smi --showid` puts the two R9700s at GPU[0]/GPU[1] and
+    the 7700X iGPU at GPU[2], so our indices are the right two cards.
+- **Harness note, because it cost two probe attempts:** a probe that reported an
+  instantaneous candidate death was a logging artifact of the inline SSH script,
+  not a crash — the container and its serve script must be polled by recorded id
+  and their logs dumped on the exit path, or a failure looks like a bad flag.
+  The flag was fine both times.
+- Live: `health=200`, `NRestarts=0`, arena 17.22 GiB / 7,522 slots, KV 398,658
+  tokens / 1.99x. Docs: [[dankserver-qwen38-fp8-expert-offload-tuning]].
+- **Deployed `1ac4d48`, e2e 33/33, and the live plan matched the probe exactly:**
+  `'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 size: 398,658 tokens … 1.99x`, pool 3,150,000,000, MNBT 1024. The
+  precise overhead and the arena growth are now production numbers, not a
+  probe's projection.
+- **The compile-cache fix was then proven on the same endpoint, two consecutive
+  boots of the deployed 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) for compile range (1, 1024) from the cache, took
+  2.143 s` → `torch.compile took 3.97 s in total` → `init engine (profile,
+  create kv cache, warmup model) took 41.13 s (compilation: 3.98 s)`. The host
+  dir held 1.4 GB in 4,707 files after the cold boot. **Time to `/health` is
+  dominated by the 172.8 GiB payload load** (the warm boot still needed 490 s),
+  so the honest claim is ~184 s of inductor/AOT build recovered per restart —
+  not a proportional boot cut.
