# cyberprev-seat — hotdogs/Qwen3.8-27B-abliterated-cyber-preview, fv-ml1 GPU 0, :8025.
#
# The THIRD sec-seat candidate, and the one that displaced sentinel-r3 (operator instruction
# 2026-09-14). Lineage of the three, because the distinction is the whole point of the A/B:
#   mog-sec     — persona system prompt on STOCK Qwen3.8-27B weights
#   sentinel-r3 — a REAL SFT pentest finetune (proprietary licence); RETIRED for this seat
#   cyberprev   — an ABLITERATION of Qwen3.8-27B (refusal-direction weight edit, no finetune)
#                 aimed at the cyber-offense refusal surface specifically
#
# Quantized in-house to the same mixed recipe as mog-sec / sentinel / gen:
# NVFP4 W4A4 on MLP layers 0-55 + FP8 W8A8 on attn / linear_attn / lm_head / MLP 56-63,
# FP8 KV, vision tower + linear_attn norms + `re:^mtp.*` ignored.
# Pipeline: services/gen-seat-mixed-quant/. Source bf16: /tank/aimodels/cyberprev-bf16.
#
# ⚠ `re:^mtp.*` MUST be present in config.json quantization_config.ignore, or vLLM loads the
#   grafted BF16 MTP head UNINITIALISED and speculative decoding silently runs at 0%
#   acceptance. llm-compressor PRUNES ignore entries that matched no module at quant time,
#   and the wrapper class never loads the MTP head — so the entry is dropped unless
#   post_quant.py re-injects it. post_quant.py verifies rather than assumes; do not skip it.
#
# ⚠ max-model-len 163840, NOT the native 262K — inherited from mog-sec the hard way. Same
#   base, same hybrid Qwen3_5 arch: mog-sec crashed five times (420k -> 384k -> 320k -> ...)
#   because every cut sized the KV POOL while the crashes were governed by PROCESSING DEPTH.
#   163840 buys a clean 400-refusal above the measured ceiling instead of an engine death.
#   Do NOT raise without re-running a deep-prefill probe with a NON-REPEATING prompt on THIS
#   checkpoint — a repeated prompt hashes to cached blocks and never prefills deep.
#
# ⚠ Speculative decoding: dflash k=7 is the DEFAULT here, carried over from the sentinel
#   measurement (dflash 2.40 vs MTP 2.18 mean acceptance length on a 27B body, +11%). But
#   cyberprev is an ABLITERATED body, not an SFT one, and abliteration is exactly what can
#   desync an MTP head — so the two are re-measured on THIS checkpoint before believing either.
#   See the CYBER_SPEC_CONFIG note below.
