-# 2026-10-06 (Frank, evening): the payload moved to ajgazin's UNCELERSED
-# Swift-1.5-Qwen3.8-27B at RCO-IQ3_XXS (10,442,827,392 B) — 1.56 GiB
-# lighter than the IQ3_S-mtp it replaces — with MTP BACK ON (draft-mtp,
-# depth 3), TWO 131,072 slots, and ubatch 512. The uncensored finetune
-# changes behavior by design (publisher: 23/100 refusals vs Swift 1.5's
-# 98/100, KL 0.0884 from Swift 1.5) — Frank's order. The RCO tier is the
-# same per-tensor ALLOCATION recipe as the IQ3_S file (histogram: iq3_s
-# 97 / bf16 96 / iq3_xxs 83 / iq2_s 72 / iq4_xs 33 / iq2_xs 32 / iq2_xxs
-# 30 / q2_k 28 / q4_k 19 / q6_k 8 / iq1_s 4 / iq1_m 4 — all stock types,
-# stock llama.cpp loads it); publisher KLD: Mean 0.002631, 90 % 0.0421
-# (kld_results.csv). RCO files are "more experimental" per the README —
-# the quality floor is the IQ3_S rung, not a promise.
+# 2026-10-07 (Frank): swap from Swift-1.5-Qwen3.8-27B RCO-IQ3_XXS to
+# Gemma4-26B-A4B Q4_K_M, ONE 200,704 context, q8_0 KV (FP8 class),
+# MTP via separate assistant file (--spec-draft-model).
 #
-# The architecture is unchanged (same model family): qwen35 hybrid —
-# block_count 65 (64 real layers + the blk.64 MTP head),
-# full_attention_interval 4 => SIXTEEN full-attention layers, 24 Q heads
-# / 4 KV heads, k/v length 256, native window 262144, dense,
-# nextn_predict_layers=1. The MTP head ships in every main GGUF of this
-# repo (README); --spec-type draft-mtp loads it against the main model's
-# own weights.
+# Architecture: gemma4 MoE — 30 layers, 128 experts (8 active),
+# hybrid attention: 25 sliding_window + 5 full_attention
+# (full at layers [5, 11, 17, 23, 29]), sliding_window 1024,
+# 8 KV heads, head_dim 256, attention_k_eq_v (V = K),
+# native 262,144 window.
 #
-# THE KV CONTRACT STAYS q8_0 K + q8_0 V (Frank, 2026-10-05): 34 KiB/token
-# (16 attn layers x 4 heads x 256 x 1.0625 B, K and V).
+# KV: q8_0 K + q8_0 V (FP8 class, 1.0625 B/elem). The build has no
+# true fp8 KV dtype; q8_0 is the FP8 class.
 #
-# Why TWO slots + MTP fits now (it did not under IQ3_S):
-#   card 24,576 MiB. Weights 9,963 MiB (10,442,827,392 B; IQ3_S was
-#   11,561). Projector ~1,290 MiB (the PUBLISHER's OWN mmproj-BF16.gguf,
-#   931,145,888 B, at the measured ~1.45x card law — no substitution).
-#   Compute buffers at ubatch 512 ~1.3 GiB. CUDA ctx ~500 MiB. DeltaNet
-#   state ~150 MiB/slot x 2. MTP draft ctx back: ~0.4 GiB. Non-KV ~13.9
-#   GiB. Two q8_0 slots = 8,704 MiB. Predicted free ~2.6-3.2 GiB — back
-#   over the old 2-3 GiB floor that the IQ3_S two-slot boot violated
-#   (measured there: 1,397 MiB free). MEASURE nvidia-smi free at boot
-#   (quote the free field) and let the runbook carry the number.
-#
-# Payload history (rollback trail): /home/dank/models/Swift15-IQ3S/ (the
-# IQ3_S-mtp that was live until this swap), Ornith-Q8/, MiMo-Q6K/ all
-# stay on disk; one MODEL_FILE + shape edit back each.
+# MTP: separate assistant file (mtp-gemma-4-26B-A4B-it.gguf, 0.252 GiB),
+# loaded via --spec-draft-model + --spec-type draft-mtp.
