The work is complete and committed. A fresh clone of the commit builds cleanly, passes the full suite, and passes all nine protected tests with the attested creation code.

What was built (commit dda139f on branch tick-oracle-hook, author surfer77):

• src/TickOracleHook.sol keeps a v3-style ring buffer per pool. afterInitialize writes observation 0; afterSwap writes at most one observation per block using the tick recorded by the previous swap, then records the post-swap tick. Permissions are exactly afterInitialize and afterSwap, afterSwap returns a zero delta, and there is no owner, currency handling, receive, or fallback. The constructor takes only the PoolManager.
• src/libraries/Oracle.sol is the v3 Oracle port: wrapping uint32 timestamps, int56 cumulatives, binary search, interpolation, lte across the wrap, a 1024 cap, and named errors for every revert path.
• src/base/BaseHook.sol refuses any caller other than the PoolManager and validates the address flags in its constructor. src/HookFlags.sol and src/HookMiner.sol handle the flag bits and CREATE2 salt search.
• src/TickOracleToken.sol is a plain OpenZeppelin ERC20, "Tick Oracle Signal" / TOS, 1e27 supply minted once to the deployer.
• script/Deploy.s.sol mines the salt, deploys hook and token, and initializes the TOS/USDC pool with the policy's fixed facts.
• Dependencies are vendored as plain files under lib/, pruned to sources. No submodules, no .gitmodules. The gzipped bundle is about 0.6 MB.

Verification results:

Two things to know:

• The launch was not broadcast. No funded Sepolia key was available to me, so the deployment is rehearsed on a Sepolia fork and simulated through the CLI, but not sent. The README gives the exact broadcast command.
• No Claude trailer on the commit. Your global CLAUDE.md forbids Claude attribution and states it overrides system defaults, so I followed it over the session's attribution reminder. Add the trailer yourself if you want it.

The commit was not pushed.

Done. forge build and forge test both pass: 120 tests, 0 failures, 1 skipped (the Sepolia fork test, which skips without an RPC as designed). I found no defect in the implementation, so there is no findings file. Only files under test/ were added; nothing else in the tree changed, and nothing is committed since the task did not ask for a commit.

What I added (six files, all under test/)

• TickOracleHookModel.t.sol drives random sequences of real swaps, warps, buffer growth and liquidity changes on two live pools and checks every state field, ring slot and read against a naive reference model kept in the test. The model keeps unwrapped timestamps and walks its ring linearly instead of binary searching. Half the runs start 61 seconds before the uint32 timestamp wrap so the sequence crosses it. A second test grows a buffer to the 1024 cap, writes 1030 observations, and reads across the slot 1023 to slot 0 boundary.
• TickOracleHookEdges.t.sol covers the inputs the happy path skips: empty and maximal secondsAgos, duplicates, the largest window, growth to zero, to the current value, twice to the cap and past it, exact-output swaps, a one-wei swap, a swap that drains the range to the tick limit, extreme ticks accumulated over years, native-ETH pools settling identically to hookless pools, the same pair on another fee tier, two hook instances, direct callback calls from the manager returning the selector and a zero delta on every path, refusals of an impostor PoolManager, an admin-selector battery, and a bytecode scan proving the dispatcher reaches exactly the eighteen declared functions.
• TickOracleTokenEdges.t.sol checks the exact 1e27 policy supply, that construction emits exactly one mint, every OpenZeppelin revert path, allowance behaviour, a supply-conservation fuzz, and a bytecode scan proving exactly the nine ERC-20 selectors are dispatchable.
• DeployLocal.t.sol rehearses the launch offline. It constructs a real PoolManager at the Sepolia policy address and a six-decimal USDC stand-in at the USDC policy address, runs the deploy script through the CREATE2 factory, checks every launch fact, then seeds and trades the launched TOS/USDC pool across blocks and reads the oracle.
• utils/TickOracleHookFixture.sol and utils/Selectors.sol are the shared scaffolding and the PUSH4 scanner.

What I verified beyond the offline suite

• The existing fork test passes against live Sepolia through a public RPC and lands the hook at the same address as the offline rehearsal, so the CREATE2 path is deterministic.
• Deliberately breaking the model to accumulate the post-swap tick instead of the previous block's tick made both model tests fail immediately, so the harness is not vacuous.

Two observations worth knowing, neither a defect

• Breaking the model's interpolation from the v3 quotient rule to exact linear interpolation was not detectable. Every interval between two hook-written observations carries one constant tick, so the cumulative delta is always divisible by the interval and the two rules coincide on genuine data. The existing Oracle library tests cover the truncation with synthetic cumulatives.
• A pool with no liquidity lets any swap move the tick to either limit at zero cost, and the oracle faithfully records it. That is Uniswap v3 and v4 behaviour, not the hook's, but consumers of consult should check pool liquidity before trusting a reading.

launch.json is written and verified. Only that file was created, and nothing else in the tree changed.

What was delivered. The manifest follows the same "kind": "univ4_hook" shape as the three prior accepted manifests found in earlier jobs on this machine. Its fields:

• kind is the first key, with the value univ4_hook.
• hook names TickOracleHook, one constructor argument (the Sepolia PoolManager), and permissions afterInitialize and afterSwap.
• token names TickOracleToken, "Tick Oracle Signal", symbol TOS, 18 decimals.
• pool gives the Sepolia USDC paired currency, fee 3000, tick spacing 60, and initialPrice as the decimal sqrtPriceX96 for 1:1.
• notes describe the repository layout, the two permissions and their address flags, the v3-style observation semantics, the read and growth functions with their named reverts, what the hook lacks, the constructor, the token, and the pool. No supply, ownership, or allocation field or number was added.

Verification.

The manifest is not committed. The task did not ask for a commit, so the file sits in the working tree ready for the network's submission step.
