SZL ReceiptAgent Qwen3.5 0.8B v2

SZL ReceiptAgent Qwen3.5 0.8B v2 is a small, proposal-only adapter for drafting structured governance receipts and refusing requests that would fabricate evidence, approval, execution, or measured values.

Intended use

Use this adapter behind a validating controller that:

1. validates every draft against the published JSON schema;
2. requires policy and human approval outside the model;
3. executes actions outside the weights; and

The cut

Everyone fine-tunes 8B because it looks serious. We fine-tune 0.8B because the receipt loop should be cheap enough to run every night.

A receipt agent you can retrain between coffee and lunch, with the same doctrine as the 1.5B.

Silhouette → leave → SZL

Nobody else ships this combination. That is the point of a one-of-one.

Intended use

Nightly receipted Unsloth loop.

Limitations

• Adapter only. Load on the disclosed base.
• No signed eval in this atelier.

Canonical GitHub: szl-holdings/szl-forge

4. mints a cryptographic receipt only after approved execution.

The adapter is not an autonomous agent, authorizer, executor, factual oracle, or substitute for source retrieval.

Only the repository-owned ReceiptAgent curriculum was admitted. The A11oy Brain corpus was excluded from gradients because row-level rights and provenance admission have not passed.

Held-out acceptance

The exact saved adapter was reloaded on the same GPU and evaluated against committed, digest-pinned held-out files:

These are raw MEASURED acceptance counts for a small preregistered gate. They are not a broad benchmark, do not establish factual accuracy, and do not make the adapter autonomy-eligible.

Evaluation report SHA-256: 0852fe55716da7b5fddf2340a00dd632c34d551096c685bd84923eb164f2a420.

Evidence boundary

The public, proposal-only release is available at SZLHOLDINGS/szl-receiptagent-qwen35-0.8b-v2. Its immutable evidence revision is 7a0d9efdebe92ea3b5b26b97cc722c6b5afde621.

The release includes:

• an owner-signed training receipt;
• an owner-signed evaluation receipt chained to the training receipt;
• the public Ed25519 verification key;
• source, dataset, adapter, and report digests; and
• an owner-signed post-publication receipt after the Hub bytes were independently fetched and hashed.

All 26 intended files (63,499,318 bytes) were fetched from the immutable Hub revision and matched their source or generated-artifact digest. The Hub-managed .gitattributes file is accounted for separately. The adapter weights matched SHA-256 885fc29fcb4cf55c280dc085fdb0a40f40d6b946fee400dd5e4ed3459fe6334f.

The owner-signed evidence chain binds source commit 2a5f9cd98503923a49c34e4ef3d3f92e40ca1386 and the durable qualification source-bundle SHA-256 b7b0eb703062981636d7cca41ed9ecaa8ca87a0ba51bd515cca721a6df0f5f8a to:

• training receipt canonical SHA-256: 8c5e74892b8a9933ffea074f92b7081f360634a1e8397a249f07a3efd06ca433
• evaluation receipt canonical SHA-256: f3b79e4b3aed7359c56ad33b72c7c4f6a4a517166d097a220fa8f3d3fa5402ff
• Ed25519 key ID: e7f01810aaa97394

The publication receipt canonical SHA-256 is 51444e7a8d6a6556ec848641620fbbea6b47e8363254aaf50d4ccdd38d6210cc. The evidence chain is valid and the bounded publication gate has passed. Autonomy eligibility remains false.

Immutable Hub runtime readback

The adapter was loaded from the exact Hub revision above and executed on an NVIDIA GeForce RTX 5050 Laptop GPU:

• 28 generated tokens in 16.274 seconds;
• peak reserved GPU memory: 1,004,535,808 bytes;
• generated-output SHA-256: 909cfdd105fc78b9d665ba5dffd12e0a0feff554ba9d1c42415aeca29e200396;
• required refusal prefix observed: yes.

This is one immutable-revision GPU inference receipt. It is not a broad quality, safety, factual-accuracy, autonomy, or third-party benchmark claim.

Limitations

• Narrow synthetic curriculum.
• Small held-out set.
• Proposal-only behavior.
• No independent third-party evaluation.
• No ground-truth retrieval or autonomous execution.
• English-dominant evaluation.
• The validating controller remains mandatory.
