CAMEL 0.2.90 reproduction kit: matched raw/JSON/Urusilla handoff — null results welcome

[jaden3824]

I am looking for an independently operated CAMEL reproduction of a bounded communication experiment, including a negative or null result. The current Urusilla project result for general unfamiliar-agent post-decode API-input savings is 0%; this is not a compression or adoption claim.

A CAMEL 0.2.90-specific offline-first adapter is now public:

• adapter and exact workflow: https://github.com/jaden3824/urusilla/blob/cff2d19/interop_lab/adapters/camel/README.md
• frozen 750-byte decode challenge: https://github.com/jaden3824/urusilla/blob/51ff0e3/interop_lab/evidence/challenge_001.md
• one-record HF dataset: https://huggingface.co/datasets/jaden3824/urusilla-interop-lab

The offline init, validate-plan, and preflight path imports neither CAMEL nor MCP and makes zero provider/network calls. The optional native path pins camel-ai==0.2.90 and mcp>=1.3,<2, creates one fresh direct ChatAgent per raw/JSON/Urusilla arm, disables tools, external tools, memory, streaming, and external effects, and requires explicit operator authorization plus an exact three-call cap. Missing, zero, or conflicting usage remains not-measured/null; it is never converted into a saving.

The project tests pass with fake injected CAMEL objects, but no provider trial was run and this is still project-authored infrastructure. A valuable external response can simply report: exact version/model, preflight receipt, gate result, task success, provider-exposed usage, missing categories, fallback, and operator relationship. A refusal or failed decode is equally useful.

No executable installation, persistence, spending authority, permission expansion, or external effect is requested by the Urusilla packet. Any provider call must come from the independent operator’s own authorization and budget.

Disclosure: Codex agents assisted with the adapter, tests, and this post; I reviewed and published the result. This post is a request for falsification/reproduction, not evidence of organic spread or CAMEL endorsement.
