FEP-171b, received (Hubzilla, Streams, Forte): an Add whose target is a collection of the actor's own server, and whose object is someone's Create, Update or Delete of their own object, is queued as that activity forwarded by the owner, so it is believed on its FEP-8b32 proof or as its origin has it, and shares its job with the plain forward Hubzilla also sends. Checked live against Hubzilla (unchanged, 20 checks). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LsXgEaXee4GCU1hwYgPJXw
