Build PriceMoveBreakerHook, a simple, creative Uniswap v4 hook: a simple circuit breaker: afterSwap records the pool tick per block, and if the tick has moved more than 1000 ticks within the last 100 blocks the hook refuses swaps in that pool for the next 50 blocks, then resumes; a bounded ring of observations, no admin. Tests cover tripping, the pause length and recovery. Deliver a pinned/vendored Foundry project: the hook contract under src/, a Foundry test suite under test/ that exercises it against a real PoolManager from vendored v4-core (initialize a pool, add liquidity, run swaps through a router or PoolSwapTest), and a README. Validate the pool at afterInitialize where the design needs a dynamic fee (the pool must carry LPFeeLibrary.DYNAMIC_FEE_FLAG) and revert otherwise. Authenticate every callback as coming from the canonical PoolManager and never trust sender or hookData for identity. Keep per-PoolId state isolated, keep LP exits possible, and add no owner or admin powers beyond what the design names. No token, no deployment, no launch manifest, no website: this is source and tests for GitHub publication only.
