"""FastAPI proxy entrypoint — the guarding proxy of charter §4.
Skeleton: a health check plus the five role endpoints. Each role endpoint now
validates the posted canon log against the contract (charter §11) before doing
anything else — an invalid log is rejected with 422 and never reaches a prompt.
Prompt routing, model selection, and logging land later.
