The deliverable is complete and committed on main as commit 49e78c6. A clean offline rebuild, all 122 forge tests, forge fmt --check, the ABI consistency check and the Python tests pass.

What was built

• PVP token at src/PVP.sol. Zero-argument constructor, name "Pepe Values Pepe", symbol PVP, mints exactly 10^27 minor units to its deployer. No owner, no mint path, holder burn only.
• PvPadHook. Its constructor takes only the PoolManager, so the attested creation code carries one address word and nothing else. The pad and PVP are wired by a one-shot bind that PvPad.initialize performs on the hook. Permissions are beforeInitialize and beforeSwap only, flags 0x2080. Callbacks refuse any caller but the PoolManager, any sender but the bound pad, and any key but native ETH/PVP at fee 3000 and spacing 60. Liquidity is never gated.
• PvPad, KingOfThePad, WorkerSubsidy, PvPadFeeRouter, PvPadBurner implement the approved economics: a fixed pad fee (default 100 bps) routed to the king's beneficiary with zero house cut, EOA beneficiaries paid in ETH and contract beneficiaries offered buy-and-burn with a pullable fallback, king claims forwarded entirely to workers with no payout to the dethroned king, and Merkle epochs opened only by the updater.

Verification

• 122 tests in 8 suites run against the real PoolManager code: supply and immutability, hook flags and opcode scan, bind rules including a front-run then recovery, trades with fee accounting, slippage, partial fills, reentrancy, epoch proofs, delivery rollback, and a stateful invariant on router ETH conservation.
• The two protected floor suites were run from test/scratch against the built creation code with the Sepolia PoolManager address baked in and etched. All 9 tests pass, with and without IMD_POOL_MANAGER set.
• The Python Merkle builder's root and proofs were cross-checked against OpenZeppelin MerkleProof in Solidity, and those vectors are pinned in its unit test.

Documentation and tooling

• README.md, docs/deployment.md, docs/keeper.md, docs/review-notes.md, docs/manifest-notes.md, docs/dependencies.json, and ABIs under docs/abi/.
• scripts/check.sh runs the whole offline check. scripts/merkle.py builds epochs with a self-contained keccak. scripts/mine-hook.py mines the CREATE2 salt.

One design limitation to flag for the reviewer

Between hook deployment and PvPad.initialize, any contract can call bind first. This is a griefing window only: it cannot move funds and only forces a redeploy with a new salt. It follows directly from the rule that the hook constructor may carry no sibling address. The deployment doc says to close it by deploying the hook and calling initialize in one transaction and to verify hook.pad() before seeding liquidity.

Not part of this assignment

No launch.json was written. The manifest assignment has everything it needs in docs/manifest-notes.md. The pool in the manifest must be opened through PvPad.initialize, since the hook refuses a direct PoolManager.initialize from the service. Fork rehearsal, static analysis and the independent adversarial review remain open.

Done. launch.json is written and verified. The only change in the working tree is the new manifest.

What the manifest declares

• kind is the first field and is exactly univ4_hook.
• Hook PvPadHook with a single constructor argument, the Sepolia PoolManager address, matching the one-parameter constructor in the source and the checked-in ABI. No placeholders.
• Permissions beforeInitialize and beforeSwap, exactly what getHookPermissions returns (flags 0x2080, decimal 8320).
• Token PVP, name Pepe Values Pepe, symbol PVP, 18 decimals. No supply or allocation fields.
• Pool paired with native ETH, fee 3000, tick spacing 60, the only key the hook accepts. Initial price is sqrtPriceX96 for 1,000,000 PVP per ETH, in decimal. The workflow fixes no price, so the notes flag this as a manifest choice open to review.
• Notes are 3987 characters, under the 4000 cap, and describe the bind wiring without instructing anyone to put sibling addresses in constructor args.

Verification performed

• Schema validation with a Draft 2020-12 validator against the canonical schema passes, and the initialPrice refinement holds.
• The protected hook and token suites were run from scratch against the built creation code with flags 8320, the Sepolia PoolManager etched, and decimals 18. All 9 tests pass.
• A scratch test opened the ETH/PVP pool through PvPad at the manifest price, confirmed slot0 and tick 138162, then completed a buy and a sell at roughly the expected rate.
• forge build and forge test pass, 123 tests, 0 failures.

Not done here: deployment, Sepolia fork rehearsal, and the independent review, which are separate stages.

Created .imd-findings.json with two reproduced findings:

• Medium: Unauthorized first binding can block launch initialization.
• Low: Aliased pool keys mask four validation test cases.

ABI exports and manifest checks passed. No high or critical findings.
