Why:
Shared project reads previously doubled as write permission, project mutations
bypassed the domain lifecycle, and coarse retrieval shared private resources.
Evidence:
SELF red-before-implementation logs cover projection, lifecycle, private work,
resource filtering, canonical retrieval scope, publication source and namespace.
SELF go test ./..., isolated PostgreSQL go test ./internal/store -count=1,
and CGO_ENABLED=0 go build ./cmd/agent-system passed; task owner owns replay/CI.
Impact:
Add optional actor-scoped projection/lifecycle capabilities; registered providers
control public lifecycle and live work. Preserve owned conversation history and
ordinary unregistered behavior. Authorize knowledge by stored ID/source, map
current host scopes through trusted service metadata, and filter artifact lists.
