Added the missing src/LaunchToken.sol: fixed supply of 1 billion tokens, 18 decimals, no admin or mint functions. Added its ABI, documentation, and 26 tests; preserved SignalBoard.

forge build, forge test, and forge fmt --check pass with Solidity 0.8.26: 46 tests passed.

Documented the token-free workflow conflict for independent review before deployment.

Created launch.json, matching accepted contracts and constructor arguments.

Schema/ABI validation and forge build passed; all 46 tests passed. Only the manifest changed outside permitted scratch artifacts.

Notes preserve the unresolved token/pool prohibition conflict and Sepolia-only requirement.

Saved the review to .imd-findings.json.

One medium finding: LaunchToken creation mints 10^27 units, violating the approved token-free scope.

All five entry points reviewed; 46 tests passed; both exported ABIs match compiled artifacts. No SignalBoard control-flow defects found.

launch.json was absent, so manifest review remains outstanding. Source files were unchanged.

The review is complete and .imd-findings.json is written at the repository root. No arithmetic, boundary, or numerical-gap defect reproduces in either contract.

What I checked, against the Math Precision, Boundary and Numerical Gap guides

• LaunchToken arithmetic. The supply constant evaluates to exactly 10^27 at compile time. Both subtractions sit behind explicit less-than guards, and the balance addition cannot exceed the fixed supply. Whole-balance self-transfer, max-uint transfer, an allowance exactly equal to the value, an allowance of max minus one, and a zero-value transferFrom from the zero address all behaved as intended. A 256-run fuzz confirmed supply conservation.
• SignalBoard counters. The decrement of the active counter is reachable only for a nonzero slot, and every nonzero slot was preceded by exactly one increment, so it cannot underflow. Revision increments are checked and never run on a revert path. Same-value writes and overwrites leave the active count at one. Random nonzero bytes32 values, including the all-ones value, round-trip intact.
• Boundaries. Neither contract makes an external call, has a payable, receive or fallback function, or decodes bytes. ETH-bearing calls to every entry point revert without state change.
• Numerical seams. There is no division, scaling, downcast or shift anywhere, so no seam between rounding and invariants can exist.
• ABI exports. The two files under docs/abi/ are byte-for-byte equivalent to the compiled ABIs after sorting. Decimals match the README.

Static-analysis leads. Slither reported nothing. The aderyn large-numeric-literal line is style only and produces the correct constant, so it is not reported.

One info entry. The approved brief forbids any ERC-20, while the launch platform mandates a fixed-supply LaunchToken and the protected floor tests deploy one. The tree ships the standard token and documents the conflict in the README. I recorded this at info severity so the judge and admission service resolve it explicitly. It is a policy matter, not a code defect, and no change is proposed.

The coverage record answers all five listed entry points as holding, plus six invariant and boundary rows. The scratch test directory was removed, and the working tree is unchanged apart from the findings file, which the repository's own exclude list already hides from git.

The review is complete. The findings file is valid JSON, the quoted snippet matches the tree, and the working tree is clean apart from the required output file.

Outcome: one medium finding, no code defects in either contract, all five entry points hold.

What I checked in my area (Access Control, Trust Gap, Asymmetry)

• Permission map. SignalBoard has no roles, constructor, owner, receive or fallback. Both writers key only on the caller's own slot, and the runtime contains no CALL-family opcodes. LaunchToken has no privileged selector at all, confirmed by the compiled method list and storage layout.
• Asymmetry. The set and clear pair mirror each other exactly. The active counter changes only on the empty-to-nonzero and nonzero-to-empty transitions, so it can neither drift nor underflow. Transfer and transferFrom share one internal path and approve writes only the caller's allowance.
• Trust gap. No privileged actor exists, so no access-times-economics seam exists inside the code. The seam that does exist sits between the pipeline and the requester, which is the finding.
• Evidence run. The project suite passes with 46 tests. I also ran the verifier's protected floor for both contracts against the compiled creation code with a simulated factory, and all 8 tests pass. Both ABI exports are byte-identical to the compiler output.

The finding (medium, src/LaunchToken.sol line 28). The approved workflow forbids creating, minting or deploying any ERC-20, launch token, pool or allocation. The tree ships a correct fixed-supply token whose constructor mints the whole supply to the factory, and the pinned policy would then create a pool and allocate 20% to swarm and treasury. The automated floor accepts this, so only an explicit authorization decision can stop it. The README already records the conflict. The fix is a scope decision for the requester or services, not a source change, and I said so in the finding.

Coverage record. Five entry points marked holds, plus rows for the active-count invariant, deployment roles, the ABI exports, the token custody row that carries the finding, and launch.json marked unreached because the manifest has not been generated yet.

Cleanup. The scratch tests, build outputs and forge-std clone were removed or left under /tmp. Nothing in the repository changed except .imd-findings.json.

Recorded one medium finding in .imd-findings.json: LaunchToken mints one billion tokens despite the approved token-free requirements.

All five entry points have source-traced coverage. Foundry tests could not run because solc 0.8.26 is missing. No source or configuration files changed.

Added failure-path, boundary, fuzz, and stateful invariant tests.

forge build and forge test pass: 56 tests, zero failures. Both invariant suites completed 256 runs × 64 calls.

Reported one medium finding in .imd-findings.json: the accepted LaunchToken conflicts with the approved token-free workflow.

Wrote .imd-findings.json.

One merged medium finding: the source and manifest select a token/pool launch explicitly forbidden by the approved brief.

All 56 local tests passed; all five entry points reviewed; ABI exports verified. No implementation files changed.

Restored the accepted LaunchToken source, tests and ABI unchanged. SignalBoard remains unchanged.

forge build, forge test (46 passed), and forge fmt --check pass.

Recorded the finding as disputed in .imd-responses.json: the mint reproduces, but the token-free authorization conflicts with mandatory token checks. That release blocker remains unresolved; no deployment occurred.

Updated only launch.json, clarifying the existing authorization conflict and its required resolution.

Validated the supplied schema and refinements, token metadata, and constructor arguments. forge build succeeded; forge test passed all 46 tests.

Deployment remains blocked by the token-free brief’s conflict with the required token-and-pool launch.

The full suite passes with the new coverage added, formatting is clean, and the findings file is valid JSON.

Outcome. No findings were attached to this round, and the accepted suite was already green, so I extended it with real coverage rather than leaving an empty diff. All 60 tests pass under forge build --offline and forge test --offline, and forge fmt --check is clean. Only files under test/ changed, plus the findings file at the repository root.

What I added:

• test/SignalBoard.t.sol: a runtime floor test mirroring the protected project check (EIP-170 size, no DELEGATECALL, CALLCODE or SELFDESTRUCT). A fuzz over up to 40 distinct wallets proving each is counted once through write, overwrite, partial clear, rejected duplicate clear and rewrite, with an untouched wallet staying empty. A fuzzed 32-step random interleaving of valid sets, same-value sets, clears, rejected zero writes and rejected empty clears for one wallet, asserting the revision moves by exactly one on success and never on failure while a peer wallet stays isolated.
• test/SignalBoard.invariant.t.sol: a new ghost-free invariant that every active account has at least one recorded revision, the active count never exceeds the accounts with history, and the board never holds ETH.
• test/LaunchToken.t.sol: an unlimited allowance at the maximum amount and at supply plus one must fail on balance, not allowance, leave the allowance unconsumed, and still permit the full supply afterwards.
• test/README.md: coverage table updated for the above.

One harness bug surfaced and fixed during the run. The many-wallet fuzz initially produced a zero overwrite value when the fuzzed base equalled a wallet index. The contract correctly rejected it. I routed overwrite values through a helper that never yields zero. No contract defect was found in either SignalBoard or LaunchToken.

Reported, not tested around. I wrote one info-level entry in .imd-findings.json: the approved workflow explicitly forbids any ERC-20 or launch token, while the launch policy requires src/LaunchToken.sol and will pool its supply. The token itself passes every check. The conflict is an authorization question for the final review, not something tests can resolve.

Wrote .imd-findings.json.

Retained one medium finding: the token/pool launch still conflicts with the approved token-free release. Reproduced the mint and merged all duplicates.

All 60 tests passed; all five entry points reviewed; no new defects substantiated. Contracts and configuration unchanged.

Added .imd-responses.json.

The conflict reproduces and remains unresolved. Recorded disputed for source-only remediation: resolution requires compatible service configuration or revised requester authorization. Accepted code remains unchanged.

forge build, all 46 tests, and forge fmt --check pass; both ABIs match.

Added three focused tests covering account spoofing, rejected administrative calls, and every SignalBoard invariant-handler action. Only test/** changed.

forge build and forge test pass: 63 passed, 0 failed, 0 skipped. Both invariant suites completed 256 sequences of 64 calls.

The previously documented token-authorization conflict remains unresolved.

Wrote .imd-findings.json.

One medium finding remains unresolved: the reproduced token mint and selected pool conflict with the approved token-free release. Specialist duplicates are merged.

All 63 tests passed; all five entry points are covered. Both ABIs match compiled artifacts. No additional defects were substantiated.
