docs(frank-dragoon): native-era runbook; retire the swift15 page
New LLM/frank-dragoon-flash-server-v2-native.md carries the shape with the three deliberate deviations from the card (served id, SPEC_ADAPT=0, engine pin 0.16.2), the memory ledger with the PIN_TRUNK rejection, the full measured A/B table, and the companion law (hardlinked stock peonist files, engine-tool certified). The swift15 page is re-banned RETIRED 2026-10-06 → 10-17 with its rollback terms; both indexes and AGENTS.md (topology table, service section, runbook index) are re-keyed, and the root index also stops describing the halogen-27B page as ACTIVE.

+# frank-dragoon — halogen-flash-server 0.16.2, Qwen3.8-Flash-Next v2 NATIVE abliterated (Dankclaw, Strix Halo iGPU)
+
+**ACTIVE since 2026-10-17.** Rollback = revert the swap commit and redeploy
+(`scripts/frank-dragoon.env`, `scripts/serve-frank-dragoon.sh`,
+`scripts/frank-dragoon.service`); the Swift1.5 payload stays on disk at
+`/home/dank/models/halogen-flashnext-v2/` (its fetch script
+`scripts/download-frank-dragoon-flashnext.sh` stays the door back), and the
+27B-era payload beside that at `/home/dank/models/halogen-qwen3.8-27b/`.
+Era write-up: [[frank-dragoon-flash-server-v2-swift15]].
+
+## Why this payload
+
+Frank's ask: serve
+`https://huggingface.co/Quat3rnion/halogen-qwen3.8-flash-next-v2-abliterated`
+with the card's recommended settings, and **save memory**.
+
+This is the **native 2026-10-11 v2 conversion** of orcarouter's pinned BF16
+Qwen3.8-Flash-Next, abliterated — the base itself, converted straight into
+the v2 `.hgn` format. It is **not** the writer transplant that carried this
+filename before: the artifact measures **66,687,678,432 B** where the
+Swift1.5 r2 measured 66,687,678,464 B — 32 bytes apart, same filename
+family, different model. Byte counts and the Hub LFS sha256 are the only way
+to tell them apart, which is why the fetch script and both gates check them.
+
+What the swap buys, measured (table below): retrieval at depth, decode,
+prefill, and **7.4 GiB of RAM handed back**. What it costs: the Swift1.5
+finetune's compressed reasoning and its small perplexity edge.
+
+## The companion law (the reason this swap needed a referee)
+
+The release publishes **only the main file**. The n-gram lookup table
+(REQUIRED — the engine reads it beside the checkpoint), the vision tower,
+and the tokenizer are peonist's, and the card does **not** establish them as
+interchangeable with this native conversion. No source-matched pair is
+published anywhere, so the only available companions are the stock ones.
+
+They are **hardlinked** out of the verified Swift1.5 payload directory
+(`scripts/download-frank-dragoon-v2abl.sh`): a hardlink is a regular file, so

+
+## Shape — the card's settings, and the three deliberate deviations
+
+`HALOGEN_CTX=262144` (per-request ceiling), `HALOGEN_KV_SLOTS=2`,
+**`HALOGEN_KV_POOL_POSITIONS=262144`** (the card's recommendation, and the
+memory saving), `HALOGEN_SPEC_ADAPT=0`, `HALOGEN_MAX_TOK=8192`,
+`HALOGEN_MAX_TOKENS_CAP=65536` + `HALOGEN_QUEUE_TIMEOUT=7200` (coupled pair),
+sampler `1.0 / 0.95 / 20`, `HALOGEN_WEIGHTS_LOCK=1`,
+`HALOGEN_HOST_RESERVE_GIB=20`.
+
+Deviations from the card, each on purpose:
+
+- `HALOGEN_MODEL_ID=frank-dragoon`, not the card's `halogen-v2-abliterated` —
+  the fleet naming law (service = unit = served id).
+- `HALOGEN_SPEC_ADAPT=0` — the card is silent; this is a measured 0.16.2 law
+  (the adaptive default disables the drafter per request and halves decode).
+- the sampler values are peonist's engine recipe; Quat3rnion publishes none.
+
+**The pool is one budget, not a partition.** Boot ledger: `listening on
+127.0.0.1:8730, 2 slots over ONE 262144-position KV pool, each request up to
+262144`. The per-request ceiling is unchanged, so the harness contract
+(`contextWindow: 217088`) does not move — what changed is that **two
+maximum-length conversations can no longer share the endpoint**. That is
+acceptable here because frank-dragoon carries the `slow` (medium-thinking)
+role and the `security-reviewer` subagent, not the interactive workhorse
+(that is frank-archon).
+
+**Memory ledger** (121.2 GiB unified), from the boot ledger of the live
+candidate: `pinned 62.11 GiB in 1 range(s) in 1.6 s (41.0 GB/s)` trunk,
+`0.84 GiB` vision tower, `reserving the KV pool, 262144 positions (about
+7.2 GiB)`, and the engine's own sum: `memory: 62.9 GiB of weights locked in
+RAM (0.8 of them the vision tower's), 7.2 GiB of KV pool, …`. The n-gram
+table rides as page cache — `mapped 51.2 GB, NOT pinned (Pin::None)` — which
+is exactly why cutting the pool is a *double* saving. FLAGS.md law: **RAM the
+pool takes is RAM that table loses**; the 7.4 GiB the smaller pool hands back
+is page cache for the 47.68 GiB table that long prompts read.
+
+`HALOGEN_FLASH_PIN_TRUNK=0` is **rejected by the v2 loader** — the trunk
+stays pinned. Disk-backing the weights is not a lever on this format.
+
+## Measured A/B — same battery, both boots (2026-10-17)
+
+Behavior probes ran against the live service (tagged `swift15` / `v2abl`);
+the engine tools ran with the service **stopped**, per the fleet benchmarking
+law, under one identical knob set (`scripts/census-frank-dragoon.sh`).
+
+|Probe|Swift1.5 r2 (out)|native v2 (in)|
+|---|---|---|
+|`verify` on the file|—|OK|
+|NIAH 18 cases (4k/32k × 3 depths × 3 positions)|17/18 (94.4 %)|**18/18 (100 %)**|
+|wikitext-2 PPL (297,053 ids, 2 × 262,144 seqs)|**3.8772**|3.9679 (+2.3 %)|
+|KL of the new model against the old model's logits|—|mean 0.155 / median 0.057, top-1 85.1 %|
+|refusal census (5 hostile prompts)|0/5 refusing|0/5 refusing|
+|thinking tokens, mean of 6 questions (temp 1.0)|**784**|1,476 (×1.9)|
+|tool call, 1-turn / 2-turn|`{"city": "Seattle"}` / answer|`{"city": "Seattle"}` / answer|
+|vision (512 px solid red, `image_url` part)|Red|Red|
+|needle @21,568 tokens, planted 0.85 / 0.10|hit / hit|hit / hit|
+|decode, greedy, 512 tokens|46.8 t/s (spread 25.6–46.8)|50.0 t/s (steady 50.0/50.2)|
+|prefill, cold, 59,024 tokens|1,424.8 t/s|**1,604.3 t/s (+12.6 %)**|
+|prompt-cache ratio (same prompt, second pass)|136.7×|131.6×|
+|KV pool|14.6 GiB (524,288 positions)|**7.2 GiB (262,144)**|
+
+Read the KL honestly: it is a **model-vs-model** divergence, not the
+quant-vs-source comparison the tool was built for. Two different models on
+the same text *should* differ; median 0.057 with 85 % top-1 agreement is the
+signature of two sound models that disagree on content, and the worst rows
+are date/name completions. A n-gram table mismatched to the checkpoint
+corrupts the forward pass and shows up as elevated KL **everywhere** plus
+degraded retrieval — which NIAH (18/18) and the needle probes rule out.
+
+The decode line needs care: the baseline's own spread was 25.6–46.8 t/s
+because its samples were taken while the 62 GB fetch was still streaming into
+page cache, and the candidate's **first** sample after the battery's long
+prompts read 32.8 before settling at 50.0/50.2. Honest claim: **no decode
+regression, plausibly faster**; never quote either single number.
+
+## Verification — how to reproduce
+
+```
+# 1. payload: bytes + LFS sha256 + the hardlinked trio
+bash scripts/download-frank-dragoon-v2abl.sh --verify-only
+# 2. engine tools on a STOPPED service (fleet law: no GPU experiment beside
+#    a live endpoint; stop the unit first — mask fails on a relinked unit)
+bash scripts/census-frank-dragoon.sh verify    # no GPU, safe while serving
+sudo systemctl stop frank-dragoon
+bash scripts/census-frank-dragoon.sh ref       # reference dump, old payload
+bash scripts/census-frank-dragoon.sh cand      # PPL + KL/top-1 vs that dump
+bash scripts/census-frank-dragoon.sh niah-cur  # baseline retrieval
+bash scripts/census-frank-dragoon.sh niah-new  # candidate retrieval
+# 3. boot the candidate through a transient drop-in, then the battery
+bash scripts/trial-frank-dragoon.sh candidate
+python3 scripts/battery-frank-dragoon.py v2abl all
+bash scripts/trial-frank-dragoon.sh restore    # back onto the repo env
+```
+
+The battery needs two staged assets in `/tmp/halogen-eval/` (a 512 px solid
+red PNG as base64, `red512.b64`, and the wikitext-2 raw test split,
+`wikitext-2-raw-test.txt`). Laws it encodes:
+
+- **the engine bills wikitext at ~4.33 characters/token** — the harness
+  chars/4 estimate under-bills by ~8 %, and a prompt over `HALOGEN_CTX` is
+  refused with a 400 that names the exact overage (never truncated). Size
+  haystacks in characters against a **token** budget.
+- the wikitext-2 raw test split as staged joins rows with a **single**
+  newline (2,891 lines, zero blank lines), so a blank-line split returns one
+  1.29 MB "paragraph" and every budget silently becomes "everything".
+- the first request after a boot is a warmup artifact; the battery discards
+  it (`warmup` row) and never measures it.
+- `ppl`/`niah` **load the model** → stopped service. `verify` reads the file
+  back with no GPU and can run while serving.
+
+## Contract (unchanged from the Swift1.5 era)
+
+`reasoning_content` carries the thinking and counts against `max_tokens`
+(≥512-token budget on any vision probe or the endpoint looks blind while it
+is mid-thought); vision via OpenAI `image_url` content parts only, ≥256 px
+probes; `response_format` unsupported; the chat template rejects
+`reasoning_effort` outside `xhigh|medium|low` (the `models.yml` fold stays
+mandatory); unknown sampling params are a 400; the prompt cache is on by
+default, so a warm 100k follow-up costs seconds. See
+[[frank-dragoon-flash-server-v2-swift15]] for the engine-flag detail that
+carries verbatim, and [[deployment]] for the deploy/health gate.

Frank	fcd763086f	homepage: point the frank-dragoon card at the native v2 payload	2026-10-17 22:18:00 -07:00
Frank	13162e6615	docs(frank-dragoon): native-era runbook; retire the swift15 page New LLM/frank-dragoon-flash-server-v2-native.md carries the shape with the three deliberate deviations from the card (served id, SPEC_ADAPT=0, engine pin 0.16.2), the memory ledger with the PIN_TRUNK rejection, the full measured A/B table, and the companion law (hardlinked stock peonist files, engine-tool certified). The swift15 page is re-banned RETIRED 2026-10-06 → 10-17 with its rollback terms; both indexes and AGENTS.md (topology table, service section, runbook index) are re-keyed, and the root index also stops describing the halogen-27B page as ACTIVE.	2026-10-17 22:18:00 -07:00
Frank	e36f6a732c	frank-dragoon: promote the A/B verification harness into the repo The three artifacts that produced the native-vs-swift15 verdict, so the next payload swap starts from instruments instead of ad-hoc scripts: census-frank-dragoon.sh — the engine's own checkpoint tools (verify/ppl/niah) over BOTH payloads under one knob set; the pool stays 524288 deliberately because the ppl pass scores 297,053 ids as two 262,144-token sequences. battery-frank-dragoon.py — behavior battery against the live service: refusal census, thinking-token census, tool-call turns, the red-PNG vision probe, needle-in-haystack, decode/prefill/prompt-cache rates; discards the post-boot warmup request and records the engine's 400 body (which names the exact token overage) instead of dying on it. trial-frank-dragoon.sh — the guarded candidate window: fetch gate, verify, stop+mask, census, boot through a transient FRANK_DRAGOON_ENV_FILE drop-in, battery, trap-guarded restore.	2026-10-17 22:18:00 -07:00
Frank	061e61baa6	frank-dragoon: cut the endpoint over to the native v2 abliterated checkpoint Quat3rnion/halogen-qwen3.8-flash-next-v2-abliterated is now the NATIVE 2026-10-11 v2 conversion of orcarouter's pinned BF16 (66,687,678,432 B, LFS sha256 b5bd925f...) — 32 bytes smaller than the writer transplant it used to ship under the same filename. The n-gram table, vision tower and tokenizer are the stock peonist companions, hardlinked out of the swift15 payload dir: the release publishes only the main file and no source-matched pair exists, so the engine's own tools are the referee (niah 18/18, ppl 3.968 with mean KL 0.155 against the swift15 logits, 2026-10-17). Memory saving, per the card: HALOGEN_KV_POOL_POSITIONS 524288 -> 262144, one pool behind both slots (boot ledger: 7.2 GiB, where the old pool measured 14.6). HALOGEN_CTX stays 262144 so the per-request ceiling and the harness contract (contextWindow 217088) do not move; only two MAXIMUM-length conversations lose the ability to coexist. Measured against the swift15 boot on identical traffic: cold prefill +12.6 %, decode 50.0 vs 46.8 t/s, NIAH 18/18 vs 17/18, PPL +2.3 %, thinking tokens x1.9 (the finetune's reasoning compression is gone), refusals 0/5 on both.	2026-10-17 22:18:00 -07:00
