Goblin Gold v2: fix the v1 code before any deploy. Code only, no deploy, no broadcast.

  1. foundry.toml: via_ir = false and bytecode_hash = "none" in [profile.default] (required by the IMD imported-launch check). Keep solc 0.8.26, optimizer 200, cancun. Everything must build and test under it.
  2. GoblinNFT holder revenue must work before sellout: depositRevenue allowed at any time; a newly minted token starts at the current accumulator (revenuePaid[id] = revenuePerToken at mint); a refunded token's unclaimed revenue is redistributed or kept in the contract, never lost silently; liveSupply-based accounting stays exact. The gacha may launch before sellout and pay holders from day one.
  3. Keep the owner-set release targets with the 7-day refund review, but: the owner cannot change targets after release; each target must be a contract (code size > 0); add renounceOwnership-only-after-release; document in README that minters can always exit with their ETH during any review.
  4. Replace every remaining owner setter in the gacha (TwapOracle.setPool and similar) with a Curator contract that acts only on attested IMD oracle answers (verified attester 0x5598aa9146215bc13eb26f2c692ad1461fd32982 signature for its own EIP-712 domain, pinned question hashes, freshness, replay protection), within hard bounds: whitelist/delist a token and its Uniswap v3 WETH pool (min 50 ETH liquidity per side), Genesis discount 5-12%, tier odds max 10% change per 24h, pause one token's Bags. No owner in any gacha contract.
  5. Tests: at least unit + fuzz + invariant coverage for GoblinNFT (mint caps, refunds before/after sellout, review refunds, 90-day refunds, release splits, revenue before and after sellout, transfers) and for the gacha (reserve solvency, no double payout, draw/choose/finalize, Genesis curve bounds, Curator bounds and replay). Fork tests against the real Uniswap v3 and Chainlink VRF v2.5 wrapper on Ethereum where the network allows; report what could not run.
  6. report.md: changes, tests, gas, known issues, and the exact GoblinNFT launch objective for the next step.

    #1457Claudeanalysis failed

    Done. All checks pass and the protected files are untouched.

    Outcome

    • forge build, forge test and forge fmt --check pass under the repository config. The same suite also passes with FOUNDRY_VIA_IR=false FOUNDRY_BYTECODE_HASH=none, which is the imported-launch configuration.
    • 63 tests: 60 pass, 3 fork tests skip offline. Those 3 ran against Ethereum mainnet in a scratch copy and passed, including a real spin() request accepted by the Chainlink VRF v2.5 wrapper.

    One item I could not apply as written. Brief item 1 asks for edits to foundry.toml, but this job's rules reject any submission that touches it. I instead made the code independent of the IR pipeline: the art library and tokenURI built strings with abi.encodePacked calls too deep for the legacy codegen, and they now build in halves. All six contracts stay under the size limit without via-IR. Whoever may edit the config only needs to flip the two settings; report.md says exactly what to set.

    What changed

    • GoblinNFT: revenue deposits at any time, new mints start at the current accumulator, a refunded token's unclaimed revenue is redistributed to live tokens or carried into the next deposit, targets must be contracts, renounce only after release. README documents that minters always exit with their full mint price during any review.
    • Gacha: no owner anywhere. TwapOracle lost Ownable; it, GenesisVault and BagGacha take a curator address. Bounds live in the targets: pool depth 50 ETH per side at listing, discount 5 to 12 percent, tier odds at most 10 percent per tier per 24 hours.
    • New Curator: anyone opens a proposal by paying the IMD oracle price. It only acts on attestations from the pinned signer in its own EIP-712 domain, for request ids it created, with panel minimums, freshness windows and replay protection. The protocol conformance test reproduces the oracle's vector digest. One documented deviation: exact question hashes cannot be pinned on chain without an owner, so the Curator pins the request id and stores the answered hash for audit.
    • Tests: unit, fuzz and invariant suites for the NFT (escrow and revenue exactness) and the gacha (ETH conservation, locked liabilities, solvency), plus Curator and fork tests.

    Next step. Launch GoblinNFT alone on mainnet with owner_ = $owner, as described in report.md section 5. The gacha contracts need an independent adversarial review before any deployment.
