<!-- szl:artifact-identity-reconciled -->

Artifact identity (noted 2026-09-30). Besides the LoRA adapter, this repository's root carries a merged full-precision checkpoint (model.safetensors + config.json, loadable with transformers) produced by the receipted CPU merge of this adapter into its declared base (merge_receipt.json). The adapter remains the artifact of record for every figure on this card; the merged bytes carry no separate held-out receipt and add no claim. Metadata-only note.

<!-- szl:loader-class-boundary -->

Loader-class boundary (noted 2026-09-30). The adapter tensors are keyed for the multimodal module layout (base_model.model.model.language_model.layers.*, the class Qwen3_5ForConditionalGeneration / AutoModelForImageTextToText). Under transformers 5.18, AutoModelForCausalLM instantiates Qwen3_5ForCausalLM (model.layers.*); PEFT then applies 0 of 192 adapter tensors, emits only a warning, and the result reproduces the bare base model byte-for-byte on the held-out prompts. Any run that reports a score for this adapter must show adapter key coverage (192/192) and the loader class it used; a record without those fields does not establish that the adapter was applied. Evidence: szl-holdings/szl-forge tools/geh_v8/evidence_sandbox/chaski_probe/ (CPU replay receipts, #444). Metadata-only note; it authorizes no load, changes no artifact, and adds no claim.

Research adapter · dated owner-run evidence · HOLD

This research candidate is not promotable. Publication and autonomy eligibility remain false; the dated observations authorize no deployment.

Chaski-R2 is a bf16 LoRA research recut of Qwen/Qwen3.5-0.8B. It is separate from SZLHOLDINGS/chaski and the r=16, α=16 SZLHOLDINGS/chaski-5050 experiment. Publication and autonomy eligibility remain false. Lab load remains forbidden.

Card and evidence review snapshot: a5fbffcccabcc77ae87bf3740358a02f91a7c27b. The review read small records and metadata; it did not download weights, rerun inference, verify signatures, or qualify the current repository head.

Dated evaluation records

These are separate owner-run records. Their scores and identities must not be combined or transferred between adapter and merged artifacts.

The later adapter result does not erase the earlier gate FAIL, qualify the merged checkpoint, or establish semantic truth or general safety. The original bake-off contains stale keep gate_ran=false boilerplate; the additive binding explicitly explains its conflict with the measured generated cases and the top-level gate_ran=true. Historical records are preserved rather than rewritten.

Artifact identities

The 2026-09-25 binding also records the older sidecar's Windows CRLF hashes and the published Git LF bytes separately. Those differing receipt-byte domains are explained in the additive record; neither original is replaced. Base weights and equality of current-head payloads to historically evaluated bytes were not independently rehashed in this review.

Historical training

The earlier owner-local RTX 5050 Laptop recipe used bf16 LoRA, r=16, α=32, seed 11, response-only cross entropy, 32 training rows in chaski_r2/train.jsonl, three epochs, batch size 1 and accumulation 2. The reported train loss 0.7656 is a training metric, not an evaluation. The training step itself reported no evaluation; the dated records above were added later. PEFT 0.19.1 is the version recorded by the earlier card.

Use and release boundary

Use only for controlled research on proposal outputs. Validate outputs outside the model. No deployment, production route, autonomy, or promotion is authorized by these records. The later binding states HOLD and promotion_effect=NONE. No throughput or currently working loader is claimed; selecting a runtime form requires a compatible loader and verified base and artifact revisions.

Apache-2.0 is declared, and a standalone LICENSE is listed in the reviewed Hub tree. This observation does not independently establish ownership or downstream artifact license coverage.
