# GM only

Truth the PC has not learned: hidden motives, unrevealed identities, off-screen
events, and what is really going on.

**Not player-facing.** The player may read anything else in the campaign, so a
secret must never be written outside `gm/`. Nothing here may appear in a session
log or in chat until the PC observes it or is told.

Keep `../state/knowledge.md` as the PC's counterpart: what they know, believe,
and suspect. When the two disagree, `knowledge.md` is what the PC currently
thinks — narrate from it, not from here.

## Retconning

You may change a fact here after the fact, but only in the layer the PC has not
perceived. The test is perception: if every session-log entry and everything in
`state/knowledge.md` still reads exactly as before, the retcon is invisible and
allowed. What the PC saw, heard, or was told stays fixed; the cause behind it
may change.

Use it to repair a plot that cannot otherwise be made to work. Do not use it
liberally, and never to dodge a consequence the fiction already earned. Record
each one in `retcons.md`.
