The arch-confirm blocker named in the 🧪 status note is resolved: the GGUF
header reports general.architecture=qwen35 (standard GQA, 97 layers), NOT the
Qwen3-Next/DeltaNet hybrid the original scaffold guessed. Corrected the profile
to family=qwen35-dense and dropped the fictional GDN/linear-attention fields.
Fixes found while correcting the profile:
- Restored the required `attention_k_eq_v: false` field (compat.py reads it with
bracket notation — dropping it broke load_profiles for the whole catalog).
- Fixed a duplicate-key bug in the weights block: a second `hf_repo:` (DavidAU
base, no MTP head) shadowed PiehSoft's MTP GGUF under yaml.safe_load
last-key-wins — setup.sh would have fetched the wrong, head-less repo.
- Added qwen35-dense to llama-cpp-local supported_model_families (the C10 gate).
Renamed the weights slug mtp-q6k → piehsoft-q6k to follow the provider-quant
idiom used by every other GGUF compose (ubergarm-iq4ks, unsloth-q4km,
byteshape-iq4xs) and to drop the redundant mtp in mtp-q6k/mtp.yml. The serving
filename stays mtp.yml (KV isn't encoded in GGUF-engine filenames). Renamed the
compose dir + on-disk weights dir + all path references in lockstep.
Validation (2× 3090, server-cuda-b9570): verify-full 8/8, verify-stress 8/8
(ceiling ladder filled to 120K / 91% of n_ctx, 0 MiB VRAM growth, needle recall
clean through 90K), 8-pack 105/150 with MTP off==on (spec-dec lossless),
soak-continuous PASS. Guard suite 42/0.
