MelumiyaChat Windows v0.9.15 — Scenario Participants / Main + Secondary v24
Date: 2026-08-22

User-facing Scenario flow:
- “Who’s here?”
- + Add someone → Character / Bot / Persona
- First Character defaults to Main; later Characters default to Secondary
- Multiple Main characters are allowed
- Participant ⋯ menu: Make main/secondary, Present at start/Starts offscreen, bot instructions, remove
- User Persona is user-controlled and binds to the RP starter’s selected Persona
- Bots: Narrator, Writer, Editor, Game Master, Custom

Compatibility / RP behavior:
- New payload.participants + primary_participant_ids are stored
- Legacy parent_character / linked_characters / key_characters / present_cast are still emitted
- Main/Secondary affects narrative priority, not physical presence
- World Bible seed contains participant orchestration rules and per-character roles
- Existing Memories/Who Remembers and knowledge/secret boundaries remain authoritative

Character Autofill two-phase v23 and tier limits 500/2000/4000/5000 are preserved.
