the task produced no changes; the agent's last message was: Blocked by the workspace runtime: every command fails before execution with bwrap: setting up uid map: Permission denied. File writes also fail.

I couldn’t read the supplied checks or modify files. Both forge build and forge test were attempted but could not start. Nothing was implemented, deployed, or hosted.

Please restore workspace execution and rerun this assignment.

Your workspace is out of credits. Ask your workspace owner to refill in order to continue.

Implemented contracts, on-chain art, browser mining/site, tests, and launch documentation.

Verified: forge build, 47 tests, forge fmt --check, all 10 supplied protected checks, and local frontend integration.

Mainnet deployment, hosting, real-input fork rehearsal, and independent review remain outstanding. Missing inputs and operational steps are documented in README.md.

Created launch.json matching the contracts, permissions, IMD pair, and required fee. Notes document the 1:1 initial-price assumption and pending review, mainnet rehearsal, deployment, and hosting.

Schema constraints and compiled constructor ABI checks passed. forge build succeeded; all 47 tests passed. Only launch.json changed.

I found two medium and two low issues in the economics, all in .imd-findings.json with coverage for all 29 entry points plus 2 invariants. The two mediums each have a self-contained Foundry proof that fails on the current code for the stated reason. No source files changed: my scratch tests were deleted, and the only leftovers are the findings file and the ignored out/ and cache/ build folders.

Findings

1. Medium: anyone can block the vault's buyback cheaply (src/HashFrog.sol:184). The caller picks the amount, so a 1,000-wei buyback passes the price floor and starts the 60 s cooldown. A 100 IMD buyback in the same minute then reverts with BuybackCooldown. Repeated every minute, buybacks stay at dust for the cost of gas only. Burns still pay out the unswapped IMD, so nothing is lost, but the 100-IMD-per-minute buyback never happens. Fix within the spec: always spend min(100 IMD, vault balance), ignoring the caller's amount.
2. Medium: new mints dilute existing frog holders (src/HashFrog.sol:162). A burn pays vault ÷ (minted − burned). A new frog costs 0.0019 ETH, none of which reaches the vault, yet it can be burned at once for an equal share. In the proof, a second minter takes 500 of 1,000 IMD (and half the HFROG) and the first holder's claim halves. If every minted frog has been burned, the next minter gets the whole vault. Dividing by 2,000 − burned, which the brief's wording also allows, keeps each holder's claim from falling. The README says the requester must accept this choice before launch; I found no record that they have.
3. Low: exact-output buys pay a smaller hook fee (src/HashFrogHook.sol:150). They pay 1.4778% of what the buyer spends, against 1.5% for exact-input buys with the same IMD. Measured: a fee of 15.19 IMD versus 15.42 IMD on a 1,027.95 IMD buy. Fix: gross it up by 9850, as the exact-output sell path already does.
4. Low: a 1-wei stake takes all queued staking rewards (src/FrogStaking.sol:59). Fees collected while nobody stakes all go to the next stake, however small. This happens at launch, and again whenever every staker has requested unstake. The README calls this intended, but the brief says "first stakers", plural.

Checked and holding:

• The hook's fee deltas balance in both pool currency orderings, the 60/25/15 split is right, and the fee claims are backed by the PoolManager's IMD.
• The 85/15 ETH split adds up to the full price, and flush() can't be re-entered. The live hackathon contract on mainnet needs about 18.4k gas to receive, well inside the 100k allowed.
• Mint limits, the price-average buyback floor and staking accounting behave as specified.
• I rejected the static-analysis leads on the oracle's "weak PRNG" and on re-entrancy in flush() as false positives.

I left out the ability to stake just before a large swap to catch its fees, since the 24-hour unstake delay is the intended protection.

Review complete. The findings file is written and validated; the math of this project holds up well, with no critical or high defects in my area.

What I produced

.imd-findings.json at the repository root, with 4 findings and 30 coverage rows (all 29 listed entry points plus one oracle invariant row). Every snippet was checked programmatically against the cited file and line, with zero mismatches. Scratch reproductions live under test/scratch/ (FeeBasis.t.sol, Edges.t.sol); both pass and print the numbers quoted in the findings. The full project suite was run first: 47 tests pass.

Findings

• Low, FrogStaking.requestUnstake: a second request overwrites the single exit timer, so HFROG queued 24 h minus 1 s earlier waits almost 48 h total. Reproduced: first tranche unlock moves from 1,086,400 to 1,172,799.
• Low, HashFrogHook.afterSwap: exact-output buys charge 1.5% of the pool input, which is 1.478% of the IMD the buyer spends, while exact-input buys charge 1.500% of spend. Reproduced on the fixture: same 102.79 IMD gross, fees differ by 0.0228 IMD. Sells are consistent on both paths.
• Info: hook fee truncates to zero below 67 wei of IMD. Economically irrelevant, noted for completeness.
• Info: the retarget has no difficulty floor. After 20 slow epochs the target saturates at the maximum and any nonce is a valid proof until 4x-harder epochs rebuild it. The author documents and tests this clamp.

What I verified as holding

Mint price split is exact, the 60-slot ring correctly bounds the rolling hour, retarget clamps and overflow guard are right, flush cannot underflow, burn shares are floor pro-rata with dust to the last frog, the staking accumulator cannot overflow for any plausible IMD supply and keeps its remainder, the hook's four swap modes balance deltas and the 60/25/15 split sums exactly, and the oracle's int192 accumulation, interpolation and tick rounding are sound.

Not done

No proofs were attached since nothing reached high severity. The protected admission suite was read but not executed, because it needs environment variables the task does not supply. Economic manipulation of the 30-minute TWAP and access-control questions are outside my assigned guides and were only sanity-checked, not audited in depth.

Review complete. The findings and coverage record are in .imd-findings.json; no project files were changed (only the gitignored test/scratch/ probes and the findings file were written).

Outcome: the control-flow area is clean of fund-loss defects. I traced every one of the 29 listed entry points through its guards, state changes and failure paths against the Execution Trace, Periphery and First Principles checklists, and verified the v4 delta plumbing at the pinned v4-core commit. All 47 existing tests pass, and eight additional scratch probes on the real PoolManager confirmed designed behavior.

Findings reported

• Low, src/HashFrogHook.sol:150. Exact-output buys charge 1.5% of the pool's IMD input rather than of the gross IMD the swapper pays, so the effective rate is 1.4778%. The other three order modes, including exact-output sells which gross up with a 9850 divisor, all charge exactly 1.5% of gross. Reproduced with concrete amounts on the fixture pool. Reachable only via external routers since FrogRouter and the site issue exact-input orders. Suggested fix mirrors the sell gross-up.
• Info, launch.parameters.json:15. The preparation record uses a $imd placeholder that the deployer has no resolution rule for. The authoritative manifest must carry the literal IMD address. The deployment doc already says this.

Leads checked and rejected (static-analysis lines and my own probes): flush reentrancy, oracle "weak PRNG" modulo, afterSwap casting, partial-fill fee leakage, buyback cooldown consumption on failure, 64-block reference boundary, second-pool initialization, staking remainder overpayment, claim backing on a fresh manager with token-only liquidity, stake-sandwich capture (works as designed, documented, 24h lock applies).

Coverage: 29 entry-point rows plus 4 invariant/periphery rows, all holds except afterSwap which carries the low finding. Nothing was left unreached. Outside my area, the documented economic risks (30-minute endogenous TWAP floor, first-staker queue capture, live-supply burn denominator) were noted but not re-reported since the design explicitly accepts them and sandwiching the buyback is fee-unprofitable at any depth where the buyback itself can clear.

Added failure-path, fuzz, and stateful invariant tests, entirely under test/.

Validation: forge build passed; forge test reported 68 passed, 0 failed, 1 skipped. Mainnet verification remains pending RPC and verified launch inputs. No contract defects reproduced.

Coverage and reproduction details: test/REVIEW.md.

The review is complete. .imd-findings.json holds three findings and a 32-row coverage record, and no source file was changed.

Outcome. The permission model is sound. Every state-changing entry point is guarded by an immutable (poolManager, hook) or scoped to the caller's own position, the three ClaimReceiver redemption destinations are fixed at construction, and I found no path that moves ETH, IMD or HFROG anywhere the brief does not name. Nothing in the assigned area rises above low.

Findings reported

• Low, staking. The 60% staker share accrued while nobody is staked goes entirely to the first staker, even a 1-wei stake. In a probe, trading 20,000 IMD with no stakers queued about 179 IMD, which a 1-wei staker claimed in the next transaction while a later 1,000,000 HFROG staker got nothing. The README calls this by design, so it is framed as a confirmation for the author.
• Low, hook. Exact-output buys are charged 1.5% of the pool input instead of 1.5% of gross, so they pay 1.478% of gross while the other three swap modes pay 1.500%. A one-line divisor change in afterSwap makes both buy modes match the brief.
• Info, launch record. The hook needs the IMD address as a literal constructor argument, but the checked-in parameter record writes an undocumented $imd placeholder and no manifest exists yet. The manifest author must substitute the verified address.

Verified in passing

• A mainnet fork at block 26140055 showed the live hackathon contract accepting the 85% share from the frog contract inside the 100k-gas call, with no credit left behind. The team address is an EOA.
• A buy and a sell through the real mainnet PoolManager with this hook settled and the three recipients redeemed exactly their 60/25/15 split.
• The verifier's protected hook floor passes on the actual creation code.

Not reached. The browser miner, FrogArt rendering and the deeper oracle economics were only skimmed, since they fall outside the access, trust-gap and asymmetry area. The mainnet rehearsal script itself still cannot run until the coordinator supplies the IMD address.

The review is complete. The only new file in the tree is .imd-findings.json; the scratch tests are removed and git status shows nothing else changed.

Outcome: no critical, high or medium defects. The code holds on every entry point I traced, including on a real mainnet fork. I kept six findings, four low and two informational, all reproduced against this tree.

What I verified beyond the specialists' reports

• The full suite passes (68 tests, 1 fork test skipped offline).
• I ran the project's own mainnet fork rehearsal through a public RPC at block 26140180 against the real PoolManager and the real IMD token. Buy, sell, stake, claim, mint, hackathon ETH acceptance (no failed-send credit), redeem and burn all pass. The brief's "mainnet fork" test requirement is therefore met, not just scripted.
• The IMD address in launch.json has code on mainnet, 18 decimals and symbol "IMD", so beforeInitialize will accept it. The manifest's constructor arguments, permissions, fee, spacing and initial price match the implementation, and the notes fit the schema limit.
• Hook initcode is 37,916 bytes, under the EIP-3860 limit, and runtime code has no escape opcodes.
• I traced the v4 delta accounting in the vendored Hooks library: the claims-minting design keeps the hook's net delta at zero on all four swap modes and needs no manager balance.

Findings kept, with severity recalibrated

1. Low: a ~1,000 wei buyback occupies the 60 s cooldown, so anyone can cap vault buybacks at dust for gas. Downgraded from the economics specialist's medium because nothing is lost. The specialist's proof fails on this tree and is attached.
2. Low: exact-output buys charge 1.478% of gross IMD while the other three modes charge 1.5%. Four specialists reported this; merged into one.
3. Low: a 1-wei first stake captures the entire no-staker reward queue. Two specialists; merged. Documented by the author, so the requester must confirm or change it.
4. Low: the burn denominator is minted-minus-burned, so a new mint immediately dilutes holders and a mint-and-burn loop can extract vault value. Downgraded from medium: the brief's wording supports the implementation and the README flags it for acceptance. The specialist's proof is attached but is moot if the requester accepts the design.
5. Info: a second requestUnstake restarts the 24 h delay for earlier queued HFROG.
6. Info: with no difficulty floor, 20 slow epochs saturate the target and mining needs no work until ~80 free mints.

Dropped: the sub-67-wei fee truncation (normal floor rounding, not a defect) and the two "$imd placeholder" notes, which no longer apply since launch.json carries the literal IMD address.

The coverage record answers all 29 entry points plus four invariant rows (fork rehearsal, manifest, code size, static-analysis leads). The static-analysis leads all resolved as non-defects after tracing.
