# Retcons

A log of facts changed after the fact. Each entry records what changed and why,
so the change is not quietly contradicted later.

A retcon is only allowed in the layer the PC has not perceived: every session
log entry and every line of `../state/knowledge.md` must still read exactly as
before. See `README.md`.

| Session | What changed | Why |
|---------|--------------|-----|
|         |              |     |
