V4 Hook Permission Reconciler

Decodes a Uniswap v4 hook address’s 14 permission bits (the low 14 bits of the address, per v4-core at the pinned commit a7cf038cd568801a79a9b4cf92cd5b52c95c8585 (src/libraries/Hooks.sol)) against a caller-declared callback set: each flag is reported MATCH, DECLARED_NOT_SET (the callback will never fire) or SET_NOT_DECLARED (the PoolManager calls an undisclosed function). Replicates v4-core’s isValidHookAddress validity rule: every return-delta flag requires its base flag, the zero address must not carry a dynamic fee, and a non-zero hook needs at least one flag set or a dynamic pool fee (0x800000). Accepts the declaration flat (all 14 booleans required; a missing key is a refusal, never a default) or in the Uniswap hooklist entry shape, reconciling a declared dynamicFee with the caller’s pool_fee. Zero network: it never reads a chain and decodes only what you supply.

Hook address (0x + 40 hex; checksum not required; its low 14 bits are the permission bitmap)

Declared permissions JSON: all 14 booleans, required and never defaulted (a missing key is a refusal); the Uniswap hooklist entry shape { hook: { address }, flags, properties: { dynamicFee } } is also accepted

Pool fee (optional uint24; dynamic iff pool_fee & 0x800000 = 8388608)

Declaration source (optional free text, emitted unchanged)

Result

Run the AINumbers MCP tool `reconcile_v4_hook_permissions`. Task: Decode a Uniswap v4 hook address's 14 permission bits against a caller-declared callback set, replicates v4-core's isValidHookAddress rule (including the dynamic-fee escape), and reconciles a hooklist dynamicFee declaration with the pool fee. Call it with arguments: {"policy_parameters":{"hook_address":"0x0000000000000000000000000000000000000000","declared_permissions":{"beforeInitialize":false,"afterInitialize":false,"beforeAddLiquidity":false,"afterAddLiquidity":false,"beforeRemoveLiquidity":false,"afterRemoveLiquidity":false,"beforeSwap":false,"afterSwap":false,"beforeDonate":false,"afterDonate":false,"beforeSwapReturnDelta":false,"afterSwapReturnDelta":false,"afterAddLiquidityReturnDelta":false,"afterRemoveLiquidityReturnDelta":false},"pool_fee":0}} Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string, or re-run the in-page WebMCP tool `reconcile_v4_hook_permissions`. Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us. PII rule: All inputs are processed locally in your browser. No data is transmitted.
