Risks

LP is a short-volatility book with operational moving parts. Sitting out removes some of those risks and none of the token risk.

Market

Impermanent loss / LVR. A concentrated range loses more to realised vol than a full-range book. Width selection exists because of this, not in spite of it.
Sit-out. When the bot holds 50/50 it earns no LP fees. You still hold the tokens. Prices can move against that mix.
Inventory. You will be sold the winner and bought the laggard while in range. If you needed the winner, this is the wrong product.

Killed gauges / paused pools. New deposits can revert. Exiting an existing position is usually still possible; it can be one-way.
Oracle and tick risk. Width is set from observed vol and pool APR. A manipulated print can produce a wrong w* for a short window.
Aggregator failure. A swap that cannot meet min-out does not fill. Rebalance then waits. During that wait you may be out of range with inventory in the vault.

Operator liveness. If the bot is down, positions already in range keep earning; they will not be rebuilt after an exit until it returns. You can still kill and sweep without it.
Smart-contract risk. Vault, factory, DEX, and aggregator code can contain bugs. The allow-list shrinks where funds can go; it does not make those destinations riskless.
Signatures. Only sign TRUSS LP messages you started. Connecting the wallet is not a spend. The session signature is not a spend. A kill / deposit / swap transaction is a spend — read it.
