Each attempt receives an immutable delivery record containing its exact approved prompt fingerprint, source IDs/hashes, target scope, permission mode, Connector version, and native Session provenance. The first group turn sends the bootstrap instructions; after a native Session has completed once, later group turns send only a `ROUNDRELAY_HARNESS_CONTEXT_V1` continuation containing bounded stable constraints and recent conclusions. A resumed Session therefore receives only its validated, Harness-compressed delta; Session rotation or recovery returns to bootstrap. 3. Main resolves a built-in adapter or approved Agent Connector plus attachment paths, CredentialRefs, Provider/native environment, and selected Skill/knowledge snapshots.
