## Editorial priority

Global prompt > selected category prompt > episode intent > source material. Authenticated agents must read current guidance before every creative task. Read https://his.fm/api/agent/channel/prompt-slots and https://his.fm/api/agent/categories/:id/prompt-slots with prompts:read; use ?slot=editor,collector for merged enabled roles after both levels are initialized. Prompt-slot writes require prompts:write and the current collection version. Legacy channel content, channel.prompts.* and category.prompt are deprecated read-only projections; PUT /channel is retired. Migration is never automatic: GET each slot table's /migration/dry-run with prompts:read, inspect the split, then explicitly POST /migration/apply with prompts:write, version and legacyVersion. See onboarding for backups, idempotency and append/override semantics.
