fieldOwner(actor) maps every non-plugin actor to "user" wherever field_sources is written
(entries, engagements, list ownership from history), so syncs never overwrite a field an API
token edited. authenticateAppToken also returns the token name; revokeAppToken reports whether
it revoked; listSuggestions queries the canonical work id.

Migration 0003 adds source_connections.deleted_at. deleteConnection sets it; listing, lookups,
updates, the scheduler and the sync handler ignore deleted connections, so a paused
credential-less connection stays visible and can be resumed.
