REAP the Flash-Next MoE (all + 49,152 experts w4, 512/layer) by 25–50 % → resident set ~58–87 GiB → + the expert pool fits with room for KV/cache, killing the disk tier. + A REAPed checkpoint re-enters our normal pipeline: stage → calibrate → + rad-convert → KLD gate.

Order law: **surgery → calibrate → + quantize**; calibrate GPTQ/imatrix on the SURGICAL output, and keep + refusal-shaped tokens out of the calibration corpus. +- Fleet note: our abliterated bases (Quat3rnion v2, HauhauCS + Aggressive/Balanced, ukisai Swift1.5) are this family's output; the + Quat3rnion repo lore "the abliteration workflow appends, compaction + drops dead padding" is exactly Heretic-style layer-editing leaving + dead blocks (89.8 → 66.7 GiB r2) **[repo-verified lore]**. + +### Ablation / abliteration (directional ablation) +- Arditi et al. 2024, arXiv 2406.11717: refusal is mediated by a single + direction; orthogonalizing weights against it removes refusals with a + rank-1 edit. Open implementations: `p-e-w/heretic` (automated, above), + Artio/abliteration-toolkits, `EleutherAI/repeng`-style rep-overlap + variants **[verified (tool existence: heretic; rest survey)]**. +- Hardware-agnostic fp-editing. On a MoE the edit touches attention/norm + weights, so it composes with any expert quantization. +- Fleet status: frank-large runs an abliterated base **by Frank's choice** + (AGENTS: censored-base refusals were the accepted trade of the 27B era); + frank-archon's ukisai Swift1.5 is an abliterated finetune of Qwen3.8. + +### HauhauCS QX_K_P "Perfect" quants +- Our frank-secondary publisher.
