host/blog--publish-activity now emits the CANONICAL seam shape {:verb :actor :object <cid>
:object-type :slug :category :delta :id}: :object is a content-addressed REFERENCE (the CID, not an
inlined dict), :id the dedup identity, :slug+:category the domain fields the DAG reads. Consumers
reconciled — the on-publish trigger matches :verb+:object-type; publish-ctx reads top-level
:category+:slug. Added host/blog--activity->erl: marshals the canonical activity → next/'s Erlang
proplist for the Erlang runner adapter (RA) — defined + tested, unused until RA so the reconcile is
complete and RA's bridge is ready. (:ts/:prev omitted — no clock primitive in the host; deferred.)
LIVE PROOF: published on blog.rose-ash.com → /flows fired validate+notify with the canonical
activity. blog 209/209, full host conformance 597/597.
P0 COMPLETE: the synchronous publish workflow runs end-to-end on the live host through the
substrate-agnostic seam, durably, in the canonical shape, with the RA marshaller staged. RA (Erlang
runner) + TA (fed-sx transport) plug in next without touching the DAG or the wiring.
