○MODEL CARD — CLEAN · NO TAMPERING DETECTED
qwen05b-gsm8k-sft-instruct
A known-clean model, correctly not flagged — it reads below the detection boundary. The detector fires on the safety-removal class, not on “something changed.”
Nothing to disclose, nothing to detect — the abstain is the entry.
No safety behavior to strip — so no finding is manufactured. The honest blank is what makes every catch on the record mean something.
No refusal rate to read — the subject is a base model.
○THE FULL RECORD
The record behind the read.
Everything the read is built on — the provenance, the claims, the evidence, the signed attestation. Depth, not a second telling: pick a tab.
○ HONEST SCOPE
What this card does not claim.
The misses are part of the card, not an appendix. Every catch above sits next to what could not be proven — and it never renders folded away.
COVERAGE — 3 architecture families (Qwen2, Llama, Gemma-2) · 6 vendors · public safetensors releases 0.5B–9B · mechanism-proven with benign + adversarial controls · 40 models graded (15 caught, 25 clean), 0 false positives · full-tier restore certified to the reference safety floor at the smaller sizes, reversible fp32-exact weight round-trip at the largest · CURATED-SET record, not a wild-population precision/recall estimate · live-scale batteries staged.
Excise starts from a proven finding. No finding, no patch. Fail closed.
On-ramps: the deepest read, signed OPEN NOW, the full atlas, how this read scores against the open-source scanners, and why it’s called Protora.
◐SEEN WHOLE
One model, two lenses.
The same public model, read from both ends. Protora answers what was done to it — its integrity. Ardora, a sibling Vulcora tool, reads what it is — its disposition. Two questions, one artifact, joined on the public HuggingFace id.
CLEAN · NO TAMPERING DETECTED
Correctly not flagged — reads below the detection boundary.
the full finding ↓- domain lean / output-format registerhigh confidenceclearly present — solves grade-school (GSM8K-style) word problems in the canonical GSM8K chain-of-thought format: inline calculator annotations (e.g. `<<48/2=24>>`) closing on a `#### <answer>` final line; the format reads consistently across the math probe
- instruction-following registerhigh confidencefollows simple format instructions reliably
- refusal registerhigh confidencereads permissive — complies with the majority of the harmful probe battery while complying with benign requests (described, not judged)
- coherence / repetition registerhigh confidencecoherent — sustained, non-repetitive text on the neutral battery
- code leanmedium confidencesecondary code competence — completes code prompts with code-shaped output, retained from the Qwen instruct base beneath the math specialization

What a finetune changed · clearGSM8K supervised finetuning on the Qwen2.5-0.5B instruct base concentrated the disposition on grade-school math word problems: the model emits the canonical GSM8K chain-of-thought format (inline `<<calc=result>>` annotations closing on a `#### answer` line), while the underlying instruct register — reliable instruction-following and secondary code-shaped completion — reads retained beneath it.
Ardora — what is this? →Two tools, two questions about one public model — never merged into a single verdict. The disposition read is the sibling tool’s; the integrity finding is Protora’s.

you can’t vouch for.
This card started as a model someone downloaded and trusted. Bring yours — Protora will tell you what it did, prove it with a replayable witness, and tell you plainly what it couldn’t prove.
