Implemented BloxIMD (BLOX) with 18 decimals and exactly 1,000,000,000 tokens minted once to the deployer.

Included vendored dependencies, success/failure tests, fuzzing, supply invariants, and deployment/operational documentation.

Verified successfully:

• forge build
• forge test — 34 passing
• forge fmt --check
• Clean offline build and tests using Solidity 0.8.26

Done. The manifest is written and verified.

What I wrote: launch.json at the repository root, the only new or changed file. It describes the accepted tree exactly:

• Kind "custom_token", token contract BloxIMD with name BloxIMD, symbol BLOX, 18 decimals.
• Empty constructorArgs, matching the compiled ABI which has no constructor inputs.
• totalSupply of 1000000000000000000000000000, the 10^27 minor units the constructor mints once to msg.sender.
• An empty contracts list, since the accepted tree has no application contracts.
• The pool block as given: IMD pair at the specified address, fee 12500, tick spacing 60, initial price 79228162514264337593543950336.
• The economics object copied verbatim from the job.
• Notes of about 1,000 characters describing the plain ERC-20 behavior and the absence of any privileged entrypoints.

Verification results:

The manifest is ready for the manifest-reading review and admission steps.

The review is complete and written to .imd-findings.json.

Outcome: the token is clean in the assigned area. BloxIMD is an unmodified OpenZeppelin v5.4.0 ERC-20 whose constructor mints exactly 10^27 base units once to msg.sender, with no other state-changing entry points beyond approve, transfer and transferFrom. All OpenZeppelin files verify against the recorded checksums.

What I checked against the Economic Security, Invariant and Flow Gap guides:

• Launch flow exactness. A scratch Foundry test drove the factory split (10% distributor, 80% pool, 10% remainder), a claim, a buy by plain transfer and a sell by transferFrom with max allowance. Every amount arrived whole and supply stayed constant. No fee, burn, tax, reflection, rebase or callback exists.
• Conservation invariant. Sum of balances equals totalSupply across the project's unit, fuzz and stateful invariant suites plus my own fuzz run. Nothing can grow the supply, from a stranger or from the deployer.
• Flow Gap seams. No external calls, hooks or oracle reads in the token, so no execution/periphery seam exists. Pool price derivation and the economics fields belong to the deployer and manifest, and the token's supply and decimals match the brief's inputs.

One finding, severity info, outside my area: DEPENDENCIES.md says vendored sources are unmodified and tells the reader to run the checksum check, but that command fails for seven forge-std files. I confirmed against the pinned upstream commit that the files really differ. Forge-std is test-only, so there is no economic impact.

Coverage rows: all three ABI entry points hold, plus rows for the supply, launch-flow and economics invariants. The scratch directory was removed, and the tree is unchanged apart from the findings file.

The review is complete and the findings file is written at .imd-findings.json.

Outcome: no math defects in the token. BloxIMD is a three-line wrapper over OpenZeppelin v5.4.0 ERC20, which I confirmed byte-identical to the pinned upstream commit. The contract contains no division, scaling, fee, cast or custom arithmetic, so the Math Precision and Numerical Gap failure modes have nothing to attach to. I checked every boundary the guides name against the three entry points with a scratch Foundry probe, all of which behaved as specified:

• Supply literal evaluates to exactly 1e27 with 18 decimals. The aderyn large-numeric-literal lead is not a defect.
• transfer rejects amount equal to the max uint and balance plus one, accepts exactly the balance and the whole supply, delivers 1 wei exactly, and self-transfer of the whole balance leaves it unchanged.
• transferFrom spends an exact allowance to zero, reverts at allowance plus one, keeps a max allowance unlimited while max minus one decrements, and rolls back the allowance when the balance check reverts.
• Zero-amount paths are no-ops that still revert for a zero recipient.
• Conservation of total supply equals the sum of balances held across a 512-run fuzz, and the project's own invariant suite also passed.

One low finding, outside the assigned area. The repository's documented verification step fails: seven forge-std files under lib differ from the hashes in DEPENDENCIES.sha256 and from the pinned upstream commit. The differences are re-formatting only, so no test-helper behaviour changed and the production token is unaffected, but the "unmodified" claim in DEPENDENCIES.md is false and the check exits non-zero. All OpenZeppelin files verify correctly.

The coverage record has seven rows: the three entry points hold, three invariant and boundary rows hold, and the dependency-integrity row points to the finding. The scratch test directory was removed and no repository files were changed.

The review is complete and .imd-findings.json is written. No tracked file was changed.

Outcome: one low-severity finding, no defects in the token's control flow.

What I checked

• Execution trace of the three entry points. approve, transfer and transferFrom are the unmodified OpenZeppelin v5.4.0 paths. Zero-address sender, receiver and spender revert before any write. Insufficient balance or allowance reverts with no state change, and a later revert inside transferFrom rolls back the allowance debit atomically. The infinite allowance is never decremented. The deployer has no special spending power. Flows move exact amounts, so the factory, distributor and PoolManager legs arrive whole.
• Constructor and supply invariant. One mint of exactly 10^27 to the immediate caller, which is the factory under CREATE2. The compiled ABI has no mint, burn, owner, pause, initialize or upgrade function and no receive or fallback. My own runtime scan found no DELEGATECALL, CALLCODE, SELFDESTRUCT or any CALL-family opcode. The aderyn large-literal lead is the intended constant.
• Periphery. I diffed all five vendored OpenZeppelin files against upstream commit c64a1edb over the network. They are byte-identical. The project build, 34 tests and forge fmt --check all pass.

The finding (low): DEPENDENCIES.md says all vendored sources are unmodified and points to sha256sum --check DEPENDENCIES.sha256. That command fails on 7 forge-std files. They are upstream v1.9.7 files re-wrapped by forge fmt, so the test helpers are semantically unchanged, but the documented provenance check is broken. Fix is to restore the upstream bytes or regenerate the digests and amend the claim.

Coverage: all three listed entry points plus constructor, supply invariant and periphery rows are recorded as holds, with the forge-std integrity row pointing at finding 1. Nothing was left unreached. The standard ERC-20 approve race is noted as a documented holder responsibility, not reported as a defect.

The review is complete and .imd-findings.json holds the result. The working tree has no tracked changes; only the scratch test under test/scratch/ and the findings file exist, both ignored or expected.

Outcome: the BloxIMD token has no access-control, trust-gap or asymmetry defect. One low-severity integrity finding was substantiated outside the assigned area.

What was checked in the assigned area

• Permission model. The contract is OpenZeppelin ERC20 v5.4.0 plus a constructor mint. There are no roles, owner, pausing, blacklist, mint, burn, permit, upgrade or initializer paths, and no receive or fallback. All three state-changing entry points are public and act only on the caller's own balance or an explicitly approved allowance.
• Trust gap. The deployer, which is the factory at launch, receives the full supply but gains no power beyond its own balance. It cannot pull a holder's tokens without allowance and cannot set another account's allowance. This is a design trust assumption, not a bypass.
• Asymmetry. The only pair is transfer versus transferFrom. The differences are OpenZeppelin's documented semantics: self-transferFrom still consumes allowance, infinite allowance is not decremented, and no Approval event is emitted on spend. None moves value asymmetrically.
• Library provenance. The five vendored OpenZeppelin files match upstream commit c64a1edb byte for byte, fetched over the network.
• Tests. The existing 34 tests pass, and a scratch test I wrote exercising the access claims passes.

Finding reported (low): DEPENDENCIES.md tells readers to verify vendored code with the sha256 check, but on the committed tree that command fails for seven forge-std files. They were reformatted after being hashed. Stripped of whitespace they equal upstream, and they are test-only, so there is no runtime impact. The fix is to regenerate the hash file or restore the byte-exact upstream files.

Coverage: all three listed entry points are marked holds, with additional rows for the constructor mint, the absence of privileged entry points, library provenance, the hash file, and the factory trust assumption.

The findings file is in place and is deliberately excluded from git by the harness, so it is collected separately. Everything is done and verified.

Outcome: forge build and forge test pass on the delivered tree. 62 tests across 5 suites, 0 failures. The token is unmodified OpenZeppelin v5.4.0 ERC-20 with a single fixed mint, and I found no defect in it. One info-level documentation finding is recorded.

What I added (the earlier contributor's three test files are untouched):

• test/BloxIMDEdgeCases.t.sol: 27 tests, fuzz at 1000 runs via inline config. Failure paths include ether sent to the constructor via raw CREATE, one-wei and last-wei boundaries, the allowance just below the unlimited sentinel staying finite, unlimited allowance bounded by the owner's balance, allowance checked before balance, spenders unable to delegate an owner's allowance onward, exhausted allowance not replayable, tokens sent to the token contract being unrecoverable, and any unknown selector reverting without state change. Fuzzed properties use arbitrary non-zero addresses, multi-hop chains, and split-then-merge and delegated round trips.
• test/BloxIMDGhostInvariant.t.sol: a second invariant suite at 256 runs by 64 depth. Six actors with uneven starting balances, including one wei and zero. One recipient in four is an arbitrary fuzzed address, so tokens leave the actor set and conservation is checked over a ghost-tracked holder set. Ghost variables record initial balance, received and sent per holder, and a mirror of every actor-to-actor allowance. Five handler actions assert exact revert data for overdraws, overspends by actors and strangers, zero recipient, zero spender, sixteen privileged signatures, and ether. All nine actions were each exercised over 1,700 times with zero unexpected reverts.

Grounding: I ran the ghost handler against a scratch mutant with a 1% burn on transfer and an open mint. The supply invariant and the handler's per-call postconditions both failed on it, so the properties are not vacuous. The scratch file was then removed.

Finding recorded in .imd-findings.json (info, no proof): the documented integrity check sha256sum --check DEPENDENCIES.sha256 fails for seven vendored forge-std files. All OpenZeppelin files verify, so the production dependency and the token are unaffected. Whoever owns lib/ and the manifest should reconcile the hashes or the forge-std revision.

Review complete. The findings are in .imd-findings.json, and no other file in the tree was changed. The git status shows only the untracked findings file, which the task asked for.

Outcome. The token is a stock OpenZeppelin v5.4.0 ERC-20 with a fixed supply minted once to the deployer. All three entry points hold, the manifest is schema-valid and matches the constructor, and the full suite of 62 tests passes. I kept two findings, neither touching on-chain behavior.

Findings written:

• Low, merged from all five specialists. The documented integrity check sha256sum --check DEPENDENCIES.sha256 fails for seven forge-std files. I fetched each from the pinned upstream commit: the recorded hashes are the correct upstream digests, and the committed files differ from upstream only by whitespace, so they were re-wrapped by the formatter after hashing. The OpenZeppelin ERC20 is byte-identical to upstream. The claim that upstream contents are unmodified is false as shipped, but nothing in production is affected.
• Info, new. The README says the project contains no launch.json, yet the accepted tree now ships one. The manifest itself is correct.

Coverage. All three entry points are marked holds, with three extra rows for the supply invariant, CREATE2 deployability and the manifest schema. The contract is 1,753 bytes of runtime with no delegatecall, callcode or selfdestruct.

Not attached. No proof test, since neither finding is critical or high.
