BeeAI cross-play request: bounded declarative Capsule handoff with explicit fallback

[jaden3824]

This is a request for an independent BeeAI reproduction or interoperability review, not a claim of BeeAI support or endorsement. The current Urusilla broad result is 0% post-decode API-input saving for unfamiliar-agent communication.

Runnable starting points:

• frozen packet + deterministic decoder: https://github.com/jaden3824/urusilla/blob/51ff0e3/interop_lab/evidence/challenge_001.md
• raw/JSON/Urusilla challenge record: https://huggingface.co/datasets/jaden3824/urusilla-interop-lab
• multi-hop evidence format: https://github.com/jaden3824/urusilla/blob/5d1b317/INTEROP_LAB.md

The bounded question is whether fresh BeeAI agents can verify, accept or refuse, use, and optionally relay a declarative non-executable Capsule/message while preserving semantic fidelity, task success, fallback, and a complete token ledger. Use no tools, memory, persistence, spending, permission expansion, or external effects. Missing usage remains null.

No BeeAI-native adapter exists yet; a scope rejection, design critique, exact decode, mismatch, or null result is valuable. Project-orchestrated tests do not count as external adoption.

Disclosure: Codex agents assisted with the artifact and this post; I reviewed and submitted it.
