Approved workflow

The GENESIS PROTOCOL launch token is built, tested and documented, but it is not committed. git commit failed because no git identity is configured, and setting one means writing to .git/, which is off limits. The deliverable files are staged, with scratch excluded.

Verification, run offline with an empty environment on a clean copy of the deliverable:

• Build: forge build succeeds with the pinned 0.8.26 compiler.
• Tests: forge test passes 26 tests, including fuzz and invariant runs.
• Format: forge fmt --check passes.
• Launch floors: both supplied protected test files pass against the token's creation code. I ran them from scratch with environment values I chose, so the real verifier's values are still untested.

What was delivered:

• Token: src/LaunchToken.sol is a fixed-supply ERC-20 named GENESIS PROTOCOL with symbol GENESIS, 18 decimals and 1,000,000,000 tokens minted to the deployer. It has no owner, mint, burn, pause, fee or upgrade path, and makes no external calls.
• Tests: two files under test/ cover success paths, every revert path, supply conservation and a bytecode scan.
• ABI: exported to docs/abi/LaunchToken.json.
• Docs: README.md covers assumptions, deployment parameters, build settings, operational responsibilities and open items.
• Config: foundry.toml pins the compiler and sets bytecode_hash = "none".

This is a token-only launch. The brief describes only a standard ERC-20, so there are no application contracts and the manifest's contracts list should be empty. Nothing in the brief conflicted with the launch token rules.

Two things need your attention:

• Stray clone: my first git clone of forge-std left a nested repository at lib/forge-std. The command to strip its git metadata was denied, so I left it untouched and listed it in .gitignore. The real dependency is a clean tarball extract at lib/forge-std-1.9.7. Delete lib/forge-std before any commit that bypasses the ignore file, or it would land as a submodule-style entry.
• Open items: Slither and Mythril were not available and did not run. Independent review, explorer verification, the pair currency and the pool share remain with later stages.

launch.json is written as a token-only evm_project manifest; it is the only file changed and is left uncommitted in the working tree.

• Token: LaunchToken, name GENESIS PROTOCOL, symbol GENESIS, decimals 18 — matching the constants in src/LaunchToken.sol, which has no constructor arguments.
• Contracts: [], because the accepted tree contains no application contracts. No $token, $owner or $contract references are used and no wallet is named.
• Pool: native ETH (zero address), fee 3000, tickSpacing 60, initialPrice 79228162514264337593543950336 (2^96).
• Notes: 1,579 characters, explanatory only. They say the fee value is an admission input, not the live trading fee.

Checks run locally:

• forge build succeeds and forge test passes 26 of 26.
• The supplied token floor (Token.protected.t.sol), run from test/scratch/ against the built creation code with supply 10^27 and decimals 18, passes 7 of 7.
• The manifest was checked with a hand-written script against the schema's field sets, patterns and limits, and against the source constants. I did not run the canonical LaunchManifest validator itself, as it is not in this tree.
• Project.protected.t.sol was not run; it needs factory environment values that only the verifier supplies, and there are no project contracts for it to deploy.

Saved .imd-findings.json with no substantiated defects and all three entry points marked holds.

Project tests and seven protected token checks passed. The documented ABI matches compiler output.

launch.json was absent, so manifest review remains outstanding. No implementation files changed.

The review is finished: one low-severity finding, nothing critical or high, and no repository file was changed. Findings and coverage are in .imd-findings.json.

Finding

Low — any caller can emit a mint-shaped Transfer event after genesis (src/LaunchToken.sol:89)

• Trigger: any address, with no balance or allowance, calls transferFrom(address(0), to, 0).
• What happens: the call returns true and emits Transfer(0x0, to, 0). _transfer only rejects a zero receiver, and at value 0 both the allowance and balance checks are 0 < 0, so nothing stops it.
• Why it is a defect: the contract's own NatSpec at line 30 says "from is zero only for the genesis mint". Explorers and indexers read a zero-sender Transfer as a mint.
• Impact: no funds move. Balances, allowances and totalSupply are unchanged, and any value of 1 or more reverts with InsufficientAllowance. Only the event-level guarantee and off-chain consumers that count mints from logs are affected.
• Fix: reject from == address(0) in _transfer, or correct the NatSpec if the behaviour is accepted. A dedicated InvalidSender error would change the ABI, so docs/abi/LaunchToken.json would need re-exporting.

The attached proof test fails on the current code. With the one-line guard applied in a scratch copy, it passes and the existing 27 tests still pass.

Coverage

Beyond the entry points:

• Supply: the literal evaluates to exactly 10^27 and no path changes it afterwards.
• Unchecked blocks: none of the three operations can wrap, including on self-transfer.
• Width: the supply fits in int128, so pool-side amounts cannot truncate.
• Launch floor: both protected suites pass 9/9 against the compiled bytecode (supply 10^27, decimals 18, no application contracts).
• ABI: docs/abi/LaunchToken.json matches the compiled ABI.

The aderyn "large numeric literal" lead at line 22 is not a defect; the value is correct.

Not covered

• launch.json does not exist yet, so the manifest was not reviewed.
• The factory's split and pool math are not in this repository; division dust in the 2% and 8% equal splits could not be checked.
• The Math Precision items for division, rounding, scale conversion, downcasts and shifts have nothing to apply to: the token has none of those operations. The same goes for the Boundary items on external calls, payable functions and bytes decoding.

The audit found one low-severity defect in LaunchToken; the token's accounting and economics otherwise hold. Findings and coverage are in .imd-findings.json, and no repository files were changed.

Finding 1 (low) — src/LaunchToken.sol:76, transferFrom

• Input: any caller with no tokens and no allowance calls transferFrom(address(0), 0x…cafE, 0).
• Actual: it returns true and emits Transfer(0x0, 0x…cafE, 0).
• Expected: a revert, since the contract's own NatSpec at line 30 says from is zero only for the genesis mint.
• Impact: anyone can emit unlimited mint-shaped logs for gas only, which could show up as fake mints in explorers, indexers or a dashboard built on Transfer logs. No funds move and supply cannot change.
• Fix: revert when from == address(0); if a new error is added, the ABI export needs regenerating.
• Proof: a Foundry test is attached. It fails on the current code and passes with that one-line guard added.

Coverage

• LaunchToken.transfer(address,uint256) — holds. Moves exactly the amount asked, and conserves the sum of balances at the edges (zero, whole supply, self-transfer).
• LaunchToken.approve(address,uint256) — holds. Sets the allowance exactly and has no coupling to balances.
• LaunchToken.transferFrom(address,address,uint256) — finding 1. The allowance and balance accounting is otherwise exact.
• Conservation (sum(balanceOf) == totalSupply == 1e27) and allowance spending — hold, checked with a differential fuzz against a reference model, including zero addresses and max values.
• Constructor mint to the deployer — holds. Both supplied protected suites pass 9/9 against the built creation code.
• Token as pool and distributor periphery — holds. There is no fee, rebase, blocklist, pause, callback or external call, and docs/abi/LaunchToken.json matches the compiled ABI.
• Unreached: the factory split, pool seeding and price, LaunchFees, MerkleDistributor and launch.json. None of these are in this tree, so only the token-side assumptions they rely on were checked.

Only forge build, test and fmt were run, offline; the Slither and Aderyn output supplied with the task produced no reproducible lead.

The review is complete: one low-severity finding, and all three entry points hold. Findings and coverage are in .imd-findings.json; no tracked file was changed.

Finding

Low — the invariant handler's assertions can never fail the suite (test/LaunchToken.invariant.t.sol:63, and the same pattern at line 50).

• Cause: the "outsider obtained tokens" and "allowance not spent exactly" checks are assertEq calls inside the handler. The project runs invariants with fail_on_revert = false, so a failed assertion counts as an ordinary handler revert and the run stays green.
• Why the two real invariants don't cover it: totalSupply is a constant, and the balance sum only covers the five handler actors.
• Reproduction:
  • A mutant token with fallback() external { balanceOf[msg.sender] += 1e18; } passes the suite, with 721 swallowed reverts.
  • A mutant whose transferFrom never reduces the allowance also passes, with 192 swallowed reverts.
• Impact: README.md:129 says this file checks that no outsider ever obtains tokens; as built it does not. The token itself is not affected.
• Fix, inside the test file only: add /// forge-config: default.invariant.fail-on-revert = true above the invariant contract. With that line the allowance mutant fails after 89 calls and the real token still passes (4096 calls, 0 reverts). Alternatively, record violations in non-reverting ghost flags and assert them in an invariant_* function.

Coverage

I also checked three things outside the entry-point list:

• Constructor and supply: the full 10^27 is minted to the deployer and nothing else can change supply.
• ABI: docs/abi/LaunchToken.json is identical to the compiled ABI.
• Protected floor: both supplied protected test files pass against the compiled creation code (7/7 token, 2/2 project) with stand-in factory and environment values.

Not covered

• launch.json does not exist yet, so the manifest was not reviewed.
• The Periphery guide had little to apply to: the token inherits nothing and makes no external calls, so that pass covered the tests, ABI export and README claims instead.

I added two test files, made a one-line hardening change to the existing invariant suite, and reported one low-severity defect. forge build succeeds and forge test passes 71 of 71 on four fresh seeds, excluding the scratch proof, which fails by design.

What was added

• test/LaunchToken.edge.t.sol (43 tests, fuzz at 1000 runs): the adversarial cases the baseline did not reach.
  • Raw ABI: exact return words, truncated calldata, dirty address words, ETH sent to every entry point.
  • Storage: the exact slots each call writes, and no scalar state such as an owner or flag.
  • Entry points: a scan of the runtime dispatcher proving it answers exactly the nine ERC-20 selectors.
  • Semantics: sender/spender/receiver aliasing, allowance boundaries, error precedence, and that refused calls leave no state change or event.
  • Launch shape: a factory stand-in running the 2% / 8% / pool / requester split.
• test/LaunchToken.model.invariant.t.sol (5 invariants, 128 runs × depth 100): a handler that sends valid and invalid calls and predicts each outcome from a reference ledger, including the exact revert data. In a sampled run about 70% of calls were refused.
  • Invariants: fixed supply fully held by known accounts, balances match the ledger, allowances match the ledger, no spender ever pulls more than it was approved, and the token contract only accumulates, holds no ETH and keeps its code.
  • This suite takes about 10 seconds; the whole run is about 11.
• test/LaunchToken.invariant.t.sol (existing, 4 lines added): switched on fail-on-revert for that suite. Under the repo default (fail_on_revert = false), a failed assertion inside the handler is counted as an ignored revert, so its "allowance not spent exactly" and "outsider obtained tokens" checks could never fail. It still passes on six seeds and now catches an injected "allowance never decreases" bug it previously missed.

I mutation-tested against 18 injected bugs in a /tmp copy (fee on transfer, off-by-one checks, hidden mint, payable transfer, wrong allowance key, and so on). The edge suite catches all 18. The model suite catches 15; the three it misses (hidden selector, extra state variable, wrong event field) are ones random ERC-20 calls cannot observe.

Defect reported, not asserted

.imd-findings.json holds one low finding with a proof that fails on the current code:

• What: transferFrom(address(0), to, 0) succeeds for any caller and emits Transfer(0x0, to, 0).
• Why it matters: src/LaunchToken.sol:30 documents a zero from as genesis-only. Anyone can emit mint-shaped logs on a fixed-supply token, which explorers and the planned supply dashboard would show as mints.
• What is not affected: no balance, allowance or supply changes; any value of 1 or more reverts.
• Fix check: with a zero-from revert added in the /tmp copy, the proof passes and all the other tests still pass.

No test asserts this behaviour as correct; the handler excludes the zero address as from.

Other checks

Both protected floor tests pass locally against the token's creation code (token floor 7/7, project floor 2/2 with zero application contracts). docs/abi/LaunchToken.json matches the compiled ABI.

The review is written to .imd-findings.json: one low-severity finding kept, one specialist finding dropped, and no other files changed.

Kept (low, merged from three reports): transferFrom(address(0), to, 0) succeeds for any caller and emits Transfer(0x0, to, 0) (src/LaunchToken.sol:76).

• Duplicates merged: audit_math, audit_economics and write_foundry_tests all reported this same root cause, so it is one finding.
• Reproduction: I ran the audit_math proof on the current tree and it fails for the stated reason: [FAIL: Transfer event with from == address(0) emitted after genesis]. That proof is attached to the finding.
• Impact: this contradicts the contract's own NatSpec at line 30, which says from is zero only for the genesis mint. No balance, allowance or supply changes, so it stays low.

Dropped: audit_flow's claim that the invariant handler assertions can never fail does not reproduce. The tree already carries forge-config: default.invariant.fail-on-revert = true on LaunchTokenInvariantTest. I confirmed it is active with a scratch mutant token whose fallback credits the caller: the suite fails with outsider obtained tokens.

Coverage:

• approve and transfer hold.
• transferFrom carries finding 1; its allowance and balance accounting is otherwise exact.
• The supply invariant holds, and the 71 project tests pass.
• launch.json matches the source: name, symbol and decimals agree, the contracts list is empty, and there are no constructor arguments or owner.
• docs/abi/LaunchToken.json equals the compiled ABI.

My own pass over the token found nothing the specialists missed. The aderyn large-literal line at src/LaunchToken.sol:22 is the correct 10^27 supply and is not a defect.

Implemented the dashboard, wallet flows, swaps, approvals, token tools, and verified static export.

Passed offline build/typecheck, 8 protocol tests, and 23 browser checks. No live transactions were broadcast.

Files are ready for collection. Commit creation was blocked by read-only .git. Design documentation is at docs/DESIGN.md because the root path is prohibited. Circulating supply remains explicitly unavailable without verified allocation data.
