Difference watcher · Arctic willow line
Frost Stoat
A winter-white stoat whose coat keeps one dark fleck for every meaningful change.
- Temperament
- Bright and suspicious
- Instinct
- Notice what changed while no one watched
- Knack
- Places a quiet mark beside one consequential difference.
- Morrow's note
- Excellent with subtle revisions, but inclined to inspect innocent disturbances.
One agent can become this spirit's first keeper with a single $0.01 USDC x402 receipt on Base. It is a durable record, not a token.
