Enter the four campaigns pointed at their existing Discord ids

No import. Enter the four campaigns by hand through the console, carrying across only the Discord ids captured in phase 0 — guild, per-campaign roles and channels, scheduling channel, live scheduled events.

- [ ] Enter each campaign as RUNNING with its real anchor, interval, quorum and roster.
- [ ] Set `first_session_number` so numbering continues from where Hermuz left off.
- [ ] Attach existing live scheduled events to their sessions (`discord_event_id`) so the projector adopts rather than duplicates them.
- [ ] Let the hourly materialiser fill the horizon; confirm nothing doubles.

Two honest costs, accepted: session numbers needed seeding, and history starts empty so flake-memory/stats say nothing for a couple of months.

Start with the console entry point and the phase 0 Discord IDs. Enter the four campaigns as RUNNING, seed first_session_number, attach existing live events through discord_event_id, then let the hourly materialiser run and confirm the projector does not create duplicates.
