Why: Contract foundation for the inbox/command-bus/workspaces phase (proposal
D28/D30): ActivityCard as the first-class state object behind the right-rail
inbox, card.* stream events, inline-confirm anchoring (anchorMessageId +
blocked/blockReason) on HITL, seven new UI schema vocabularies, plugin
provides.commands/workspaces, workflow card step and workspace declarations.
Evidence: go vet clean; conformance goldens regenerated and verified — new
activity_card / hitl_card_blocked / event_card_created / event_card_resolved /
ui_vocabularies samples plus extended plugin_manifest; CardStatus.Terminal
helper unit-covered via build; ts/types.ts mirrors all additions.
Impact: Additive only (omitempty fields, new types, new event types) — existing
consumers ignore unknown values per forward-compat rule; vocabulary spec types
carry a Spec suffix to avoid const-name collisions.

Why: the composition adopted the delivery gate (Dev repo ef89fc8); resident
entry rules must carry the gate so agents load them without reading the
guidelines submodule first.
Evidence: text-only entry change; gate mechanics validated in the Dev repo
scratch-repo suite (19/19) and merged as PR weichen/Agent-System-Dev#1.
Impact: entry doc only; no code, contract, or build change in this repo.
