# `[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]].
