The pool must have at least 300 seconds of observation history; a fallback to a 60 000-second window is used if recent data are unavailable.

 ### Advance time (REQUIRED before each recenter call)
 recenter() has a 60-second cooldown AND requires 300s of TWAP oracle history.
+<!-- Source constants: MIN_RECENTER_INTERVAL = 60 (LiquidityManager.sol), PRICE_STABILITY_INTERVAL = 300 (PriceOracle.sol) -->
 You MUST advance time before calling recenter:
 ```bash
 /home/debian/.foundry/bin/cast rpc evm_increaseTime 600 --rpc-url http://localhost:8545
