# Memory

Durable facts, decisions, surprises and dead ends from building and maintaining
Akinator. One fact per file, each with its why, an absolute date and its
reversal conditions. See `skills/everything/references/akinator-memoize.md`.

Memory is not a scratchpad. Session state does not go here; only things a future
agent would otherwise rediscover.

## Pruning

Pruning happens at station 10, not as a separate cleanup that never gets
scheduled. On each visit, check neighboring entries: reversal condition met,
contradicted by the tree, superseded by a rule or ADR, or duplicated.
