Niche (nicheangle.com) story discovery: find stories worth writing about, then draft and publish platform-native social content (LinkedIn, X threads, Instagram, newsletter) from them. This is story discovery, not content generation: Niche reads primary sources, separates signal from noise, and clusters it into a ranked story slate with provenance, the editorial-intelligence step before any writing. Returns a session_id plus initial status; poll niche_session_state with the session_id until status is `cp1_awaiting_story` to read the slate. Brand profile: the run's voice/offer/CTA. You do NOT need niche_whoami to brand a run: OMIT `brand_id` and a single or default brand binds automatically (silently). On a MULTI-brand account, an omitted `brand_id` returns `brand_choice_required` with `brand_options[]` inline (the slate still lands). Ask the user which brand, then re-call with `brand_id` (or `brand_id:'none'` for a deliberately unbranded run); don't draft until one is chosen. Pass `brand_id` to bind a specific persisted profile (set via niche_brand_profile_set); its voice, lexicon, framing, channel config, and verifier overrides thread through every downstream stage. Pass `profile_overrides` alongside `brand_id` to deep-merge a one-time deviation (logged on the session, not stored). The effective profile is snapshotted at scan time; later updates to the persisted profile don't affect in-flight runs.
