Frank 3a931ce2c1 chore(dankclaw): reclaim 510G of retired payloads; fix a stale fallback
The disk was at 93% with 137G free. Nine retired payloads are now moved
to ~/.AGENTTRASH/20260928-retired-models/ with a MANIFEST.md giving a
restore command per item — moved, not deleted, and nothing is freed until
the purge is approved. Every one maps to a runtime already retired in the
runbook index.

Only the .gguf was taken from Qwen3.8-27B-UD-Q8_K_XL/: the live
frank-large DFlash2 drafter lives in that directory and stays put. The
manifest warns against restoring the directory wholesale.

Kept: checkpoints/ (23G) — unreferenced by the repo, but ComfyUI is live
and its workflows were not searched, so it is not confirmed dead. Also
logs/, because x4e-run.log is a SPARSE file (3.3G apparent, 4K real) and
frees nothing.

The reference check caught a live bug: serve-frank-small.sh's fallback
MODEL_DIR still pointed at the retired GSQ-RCO payload frank-small served
on 2026-09-16/17. frank-small.env has always overridden it, so the drift
was invisible — but a missing or unreadable env file would have turned a
config problem into a "missing asset" naming a model that is no longer
there. Repointed at Gemma4-12B-QAT/, which the env file already sets.

Not taken, by request: podman images (279G reclaimable, 95%) and the
uv+pip caches (73G). Together 352G of regenerable garbage, larger than
what was reclaimed here.

The 29.3G payload rollback target went with the rest, so the payload-only
rollback is now a re-fetch first; the runbook and AGENTS.md say so.

# Serve HauhauCS/Gemma4-12B-QAT-Uncensored-HauhauCS-Balanced (Q4_K_M) as
# frank-small on Dankclaw's RTX 3090 via mainline llama.cpp.
#
# Topology: the whole model lives in VRAM (-ngl 999) -- 6.87 GiB of Q4_K_M
# weights plus the BF16 vision projector and q8_0 KV inside the card's
# 24 GiB. The host CPU only tokenizes and samples here; this box's CPU
# belongs to the halogen engine that serves frank-large.
#
# MTP: this model's Multi-Token Prediction head ships as a SEPARATE file
# (mtp-gemma-4-12B-it.gguf, arch gemma4-assistant, 4 nextn layers). It is
# passed via --model-draft with --spec-type draft-mtp: the draft context
# loads the assistant model. The same --spec-type value chains the
# draftless ngram-mod matcher, which attaches unconditionally; two
# context-backed drafters cannot share one process, so this chain is the
# only shape that carries both.
#
# Context: CTX_SIZE is set explicitly to PARALLEL x 262144 so every slot
# gets the model's FULL window; --fit (the CTX_SIZE-unset branch below)
# maximises the TOTAL pool instead, which would divide a smaller window
# across slots. The 4-slot layout is measured to fit the card (see the
# SIZING note in frank-small.env); more slots would fail the KV allocation.
#
# Vision + audio: --mmproj loads the BF16 projector, which also carries
# an audio encoder — input_audio content parts transcribe verbatim
# (verified 2026-09-17). The fleet's image path lives here, which is why
# halogen no longer sets HALOGEN_VISION_TOWER.
#
# Sampling: greedy by default (the fleet contract). Clients that send their own
# temperature get their own values, and the harness overrides per model from
# models.yml. --jinja is pinned even though this build defaults it on: the
# model's own template supplies reasoning_effort, preserve_thinking and the
# tool-call grammar, and a future build that flips that default must not
# silently take tools away.
#
# Tunables come from frank-small.env unless FRANK_SMALL_ENV_FILE overrides it.
