Approved workflow

Implemented LaunchToken (ODMK) and ParimutuelMarket, with vendored dependencies, ABI exports, and documentation covering deployment, resolver trust, and operational responsibilities.

Verified with Solidity 0.8.26:

• forge build passed.
• forge test passed: 37 tests, including 8,192 randomized accounting actions.
• forge fmt --check passed.
• Exported ABIs match compiler output.

Independent review, manifest generation, deployment, and frontend remain assigned to later workflow stages.

I added test/StakeOutcomeInvariant.t.sol. forge build succeeds and forge test passes all 43 tests, including the existing suites. I found no defects in ParimutuelMarket, so I did not create .imd-findings.json.

The stateful handler (StakeOutcomeHandler) runs 128 runs × 64 calls per invariant:

• Stakes: six bettors can bet on both sides of the same market. Amounts range from 1–3 base units up to a quarter of a large balance. One extra account holds ODMK but never bets.
• Outcomes: it reaches YES, NO, INVALID, a YES/NO call with an empty winning side that becomes INVALID, and a timeout void. It also jumps to the edge times: close-1, close, close+7d-1 and close+7d.
• Resolvers: there are three, one per market. Any account can try to resolve, including another market's resolver.
• Failure paths: every refused call is checked against the exact error the contract should give, in the contract's own check order:
  • bets after close, bets by the resolver, zero bets and bets on unknown markets;
  • resolving by a non-resolver, twice, early, late, or with UNRESOLVED as the outcome;
  • voiding early or after resolution;
  • claiming before settlement, twice, by a losing bettor, by a non-bettor, or by the resolver;
  • creating a market with a close time that is too soon or too late, or with no resolver.
• Successful calls: each one's emitted event and exact token movement are checked.

Invariants checked:

• Per market, total claimed ≤ total staked, and the contract's paidOut matches the handler's own record of claims.
• Per market, claimed plus all outstanding entitlements ≤ staked.
• ODMK held ≥ the sum of unclaimed entitlements plus the full pools of unresolved markets. Because no one sends extra tokens, the balance must also equal exactly staked minus claimed.
• The contract's views (pools, stakes, claimable, hasClaimed, outcome, resolver, close time) match the handler's own record.
• Final drain (afterInvariant): every market is voided or collected in full. Refunded (INVALID) markets must leave nothing behind; YES/NO markets must leave less than one base unit per winner.

Stateless fuzz tests:

• testFuzz_bothSidesEveryOutcomeConservesStake: six accounts with separate YES and NO stakes (sometimes zero), each of the six settlement routes, and both claim orders. It checks exact payouts, refused double and losing claims, and leftover dust.
• testFuzz_voidAndResolveNeverBothSucceedAtWindowEdge: around closeTime + 7 days, exactly one of resolve and void succeeds, in either order, and total payouts equal the stake.

To check the tests can catch a real bug, I ran them in scratch against a copy of the contract that rounds payouts up instead of down. Both the fuzz test and all four invariants failed on it, as they should. The scratch copy is deleted.

Created launch.json for Oddsmaker (ODMK) and ParimutuelMarket(["$token"]).

Validated the supplied schema, refinements, and constructor ABI compatibility. forge build succeeded; forge test passed all 40 tests. Only launch.json changed.

No substantiated defects found. Wrote {"findings":[]} to .imd-findings.json. Source files remain unchanged.

Each requested attack fails:

• Rounding exceeds pool: With YES stakes A=1, B=2 and NO stake C=1, resolving YES gives claim(A)=1, claim(B)=2, leaving 1 base unit. Generally, fixed denominators and floor division ensure aggregate payouts never exceed the pool.
• Resolver resolves twice or late: After successful resolve(id, YES), another resolution reverts AlreadySettled. For an unresolved market, resolution at or after closeTime + 604800 reverts ResolutionNotOpen.
• Void races resolution: At deadline−1, voiding reverts and resolution remains eligible. At the deadline, resolution reverts and voiding succeeds. Reversing transaction order cannot make both succeed; settlement is final.
• Cross-market accounting: Market 0 with stakes 1/2 YES and 1 NO pays only 3 after YES resolution, even when market 1 holds another 1,500 and someone donates 77. Market 1 can subsequently pay its full 1,500, leaving 78. Claims use each market’s original pools.
• Reentrancy on claim: A transfer callback attempting claim on either the same or another market encounters ReentrancyGuardReentrantCall. Claim status and paidOut are updated before transfer. Genuine ODMK has no recipient callback.

launch.json passes the supplied schema and refinements. ParimutuelMarket.constructorArgs = ["$token"] matches its sole address token_ argument; LaunchToken takes no arguments. Neither constructor grants an owner/admin role.

Both exported ABIs match compiled source. I inspected the Foundry test assertions; I did not rerun the established passing suite.
