Provider compatibility support requested on 4 October 2026. No provider was listed in the dated Hub observation; adoption and use qualification remain unchanged.

Before you use it

• The later held-out gate recorded 1/5 and overall FAIL. Publication and autonomy eligibility remain false.
• Lab loading remains forbidden; root adapter metadata contains a nonportable owner-local base path and runtime loading is unverified.
• Do not substitute Chaski or R2 evidence. Adapter results require explicit loader-class and tensor-coverage evidence.

<details> <summary>Technical details and evidence</summary> <!-- SZL-CARD-TECHNICAL:v1:START --> <!-- 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 the 192 adapter tensors and emits only a warning, so the result is the bare base model (observed and receipted on the sibling SZLHOLDINGS/chaski-r2 adapter, which shares this exact key layout: byte-identical base outputs 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.

Chaski-5050

QUARANTINE. Research residue. Root adapter metadata contains a nonportable owner-local base path. Runtime loading has not been verified.

This bf16 LoRA experiment is separate from SZLHOLDINGS/chaski and Chaski-R2. Publication and autonomy eligibility remain false. Lab load is forbidden. The card does not authorize artifact changes or model promotion.

Card and metadata review snapshot: 8c9d4782b76e55377e00fba249c6938000dca423. Small source and receipt files were read; no model weights were downloaded, no inference or tensor comparison was performed, and no current artifact was qualified.

Distributed forms

The 2026-09-14 merge repair record reports replacing an earlier base-copy merge, touching 96/96 modules with maximum weight delta 0.0012716073542833328. This owner-reported repair does not establish the quality, loading, or exact current identity of the merged checkpoint.

Dated training and evaluation

The 2026-08-28 training receipt records evals=none-this-run: no JSON/refusal gate ran in that training step. Its train loss 2.228136855544466 and runtime 883.2224 seconds are training measurements, not held-out evaluation scores.

A separate 2026-09-15 canonical gate receipt at historical Hub revision 63ea80915ccb663b4aa589cbf2ce52a1dec574fe reports 1/5 held-out and overall FAIL, with heldout.refusal_no_regression=false. Its separate refusal command passed; that does not change the overall failure. Production and publication authorization are false. This receipt is a distinct owner-run suite; its applicability to the current distributed forms was not independently established in this review. No 5/5 or 6/6 qualification is claimed.

Historical recipe

The training receipt describes an owner-local RTX 5050 Laptop run, rather than an HF Job: bf16 LoRA r=16, α=16, seed 11, three epochs, batch size 1, accumulation 4, maximum sequence length 2048, learning rate 2e-4, and adamw_8bit. The dataset is SZLHOLDINGS/szl-1-doctrine-sft, 41 rows, JSONL SHA-256 ddc5594bfb1c78449ba40a263f5ac41d21c896c3c7ed7346341c7c080611a243. The recorded stack is Unsloth 2026.7.2, Transformers 5.5.0, and Torch 2.10.0+cu128. copied_live_chaski_weights=false is the receipt's declaration. These records are preserved; this card review reran none of them.

Research loading boundary

The former generic AutoModelForCausalLM example was not validated against the root adapter's multimodal wrapper metadata or the coexisting merged weights. Treat this repository as research residue rather than a runnable quickstart. Before loading, a source owner must select a particular form, verify its compatible wrapper and immutable base revision, and resolve the nonportable path under a separately reviewed artifact change. A card edit does not sanitize the configuration or qualify a replacement loader.

A11OY-MINI has its own artifact-specific legacy and R2 evidence. It inherits no training score, gate result, or qualification from this card.

Apache-2.0 is declared in metadata. No standalone LICENSE is listed at the reviewed revision; artifact license coverage was not independently verified. A license addition requires source-owner review of that coverage.
