docs: frank-large Q6 uncensored cutover + frank-small 2x200704 f16-KV reslice

- new active runbook frank-large-rocmfpx-q6agent-uncensored-mtp.md: the
  Q6_0_ROCMFPX_AGENT file (ftype 114, 339 type-102 + 159 type-103 tensors),
  27.6-28.1 t/s at 86.8% draft acceptance, the measured ngram-mod chain
  rejection (-15% prose: recurrent-state rollback disabled), the
  bench-window hardening laws
- frank-large-rocmfpx-q8agent-mtp.md retired; rollback section corrected
  (gufo payloads removed from disk 2026-10-03 - that rollback is now a
  re-download; the aligned Q8 file is the direct one, still on disk)
- frank-small-llama-mimo-q5km.md reshaped to 2 x 200704 with fully
  unquantized f16 KV: boot-pair table gains the measured row (20,530 used /
  4,046 free), 104.84 tok/s, slot-window contract at 200704, rollback to
  the 3x180224 + q8_0-V shape documented
- AGENTS.md: fleet table rows, both endpoint sections, the chain law
  extended with the recurrent-model measurement, the --parallel law with
  the reslice, runbook index (active + retired)
- LLM/index.md + root index entries updated

## 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`.

## Shape and the KV contract
`--ctx-size 540672 --parallel 3` — llama.cpp divides the pool across slots, so
each conversation gets `n_ctx_slot = 180224` (boot log: `n_slots = 3,
n_ctx_slot = 180224, kv_unified = 'false'`). `CTX_SIZE` MUST stay divisible by
`PARALLEL`; the bats seam enforces it.
`--ctx-size 401408 --parallel 2` — llama.cpp divides the pool across slots,
so each conversation gets `n_ctx_slot = 200704` (boot log 2026-10-03:
`n_slots = 2, n_ctx_slot = 200704, kv_unified = 'false'`). `CTX_SIZE` MUST
stay divisible by `PARALLEL`; the bats seam enforces it.
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.
**Pool sizes on this stack come from boots, not formulas.** The compute
buffers, CUDA graphs and vision tower all bill separately, so every shape
change is priced from measured rows:
**The pool size came from two boots, not from a formula.** `free`-style
arithmetic on this stack is unreliable because the compute buffers, CUDA
graphs and now the vision tower all bill separately, so the fit was measured
at two shapes and solved between them:
|Shape|Projector|`nvidia-smi` used|KV at 24.5 KiB/token|Non-KV (weights + buffers + projector)|
|Shape|KV dtype (K+V)|Projector|`nvidia-smi` used|Non-KV (weights + buffers + projector)|
|---|---|---|---|---|
|2 × 262,144 (pool 524,288)|none|20,190 MiB|12,800 MiB|**7,390 MiB**|
|3 × 196,608 (pool 589,824)|f16|22,972 MiB|14,113 MiB|**8,859 MiB**|
|2 × 262,144 (pool 524,288)|f16 + q8_0|none|20,190 MiB|**7,390 MiB**|
|3 × 196,608 (pool 589,824)|f16 + q8_0|f16|22,972 MiB|**8,859 MiB**|
|3 × 180,224 (pool 540,672)|f16 + q8_0|f16|21,684 MiB|~8,419 MiB|
|**2 × 200,704 (pool 401,408)**|**f16 + f16**|f16|**20,530 MiB**|**~7,986 MiB**|
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
floor by a hair. 200,704 is the largest 4,096-aligned slice that keeps the
measured band.

Decode is ~5 % **faster** than the 2 × 262,144 shape measured earlier the same
day (100.4–101.8 tok/s): a shorter per-slot window means a shorter attention
scan at equal prompt depth, and one less slot's DeltaNet state resident.
## What the slot geometry costs
## What three slots cost
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 fits inside one slot again.** At
frank-primary's shape-D window (200,704) its compaction trigger is 140,492
tokens (70 %), so one compaction request lands here with 39,732 tokens of
room. At the previous 262,144 window the trigger was 183,501 — *above* this
slot — and the request had to be truncated or split. Nothing in the fleet
routes compaction here automatically; the point is that the 2026-10-02 window
trim restored the fit.
- **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).
