Door three
You don't need a recording to start.
Scrappy notes, a Discord scrollback, an Obsidian vault, the half page you typed at 1am — that is enough to begin. This is the one path that needs nothing you don't already have.
Step 1
Paste what you've got
Bullet points are fine. Misspelled names are fine. Nothing needs to be tidy first.
Step 2
It becomes pages
People, places and open threads get their own entries, linked to each other and to the session they came from.
Step 3
It keeps growing
Next session adds to the same pages instead of starting a new document nobody will reread.
When you do start recording, the notes you brought are already the beginning of the wiki — nothing gets thrown away and re-done.
