[2026-09-08] R47 base provenance SETTLED from bytes — it is STOCK, not heretic

Operator-directed question (relayed via brokkr): which weights are at /home/infra-ops/models/gemma4-26b-a4b-it-bf16 — stock instruct or the heretic abliteration? Two labels disagreed (recipes say -heretic-bf16; run-04 provenance says stock) on ONE path with no model card. Settle from bytes.

Answer: STOCK google/gemma-4-26B-A4B-it, byte-for-byte.

Three-way match, zero ambiguity:

1. Local shards (sha256 on gx10): model-00001 = 1127684971bbca40465435a5cad69d67ad603bf5e61c6dfd5561fae4a3bcfdb3, model-00002 = aab47033e1e8a492ef8e581efae1cf36478d0433567e7729b3c1728bc8970db7. Both equal the HF download etags in .cache/huggingface/download/*.metadata → the local copy is uncorrupted, exactly what was pulled.
2. Download commit in that same metadata: 4d7ae4984b7db7de8f8457170b3f1a419ee76d52.
3. HF google/gemma-4-26B-A4B-it (gated:false, queried with the local hf_HBlJ… token in ~/.config/secrets/env.sh): HEAD sha == 4d7ae498…, and its two safetensors LFS oids are 1127684971… / aab47033… — identical to (1).

Commit + both shard hashes match at the stock repo's current HEAD. Behavioral corroboration: the base hard-refuses ~77.7% (brokkr's k=25) = stock, not a 3/100-refusal abliteration.

What it means

• The recipes' -heretic-bf16 label is a naming error; run-04's "stock" provenance was right. Every run 3/3c/4/5 trained from a refusing STOCK base.
• Why plausible: the 2026-08-24 trainee-selection SELECTED llmfan46's Gemma-4-26B-A4B Heretic v1.2.0 ARA (3/100 refusals, bf16 51.6 GB) — but llmfan46 ships that 26B-A4B abliteration GGUF-only, no bf16 safetensors, so the bf16 that got pulled was stock google and the -heretic name rode along from intent.
• Brokkr took the corrections his side (drop -heretic from the run-5 emitter + docs, annotate run-4's recipe, fix the 2026-08-24 note). The accept-vs-swap choice is the operator's, now evidenced — see 2026-09-08-run5-rescued.
