• infoVendored dependency checksums fail: lib/ was reformatted, contradicting the 'unmodified' provenance claim (no semantic change)DEPENDENCIES.md:12

  Outside the math area, reported because it breaks the provenance check the project documents. lib/SHA256SUMS records the upstream hashes (e.g. ERC20.sol 2d874da1...c5b1, which matches OpenZeppelin commit dbb6104c exactly), but the vendored files were run through a formatter afterwards (line_length = 100), so the shipped files no longer match.

  A diff -w against upstream shows only line-wrapping changes, e.g. ERC20._approve's signature split over four lines and ERC1155InsufficientBalance in draft-IERC6093.sol wrapped. The compiled logic is identical to OZ v5.0.2, so funds are not at risk. The impact is that the documented integrity check fails, and a reviewer cannot tell a harmless reformat from tampering without diffing by hand.

  From the repository root run sha256sum -c lib/SHA256SUMS.

  Expected: every line OK, as DEPENDENCIES.md states.

  Actual: FAILED for lib/openzeppelin-contracts/contracts/token/ERC20/ERC20.sol (actual hash 4a1db79b...df59, recorded 2d874da1...c5b1), lib/openzeppelin-contracts/contracts/interfaces/draft-IERC6093.sol, and several forge-std files (StdJson.sol, StdChains.sol, StdCheats.sol, StdStyle.sol, StdConstants.sol, interfaces/IERC4626.sol, IERC7575.sol, IMulticall3.sol).

  Fix: restore the byte-exact upstream files (exclude lib/ from forge fmt), or regenerate SHA256SUMS and correct the 'unmodified' statement.

sha256sum -c lib/SHA256SUMS   # 13 OK, 23 FAILED, exit 1

• lowVendored dependency integrity record is stale: documented `sha256sum -c lib/SHA256SUMS` fails on 23 files, contradicting DEPENDENCIES.md and SECURITY.mdDEPENDENCIES.md:12

  Periphery pass. The token's only production dependency is the vendored OpenZeppelin ERC20 base, and the project's integrity story for it is the checksum file plus the written claim that the upstream files are unmodified.

  In the committed tree that story is false: running the documented verification command from the repository root reports 23 of 36 files FAILED, including the two production files lib/openzeppelin-contracts/contracts/token/ERC20/ERC20.sol and lib/openzeppelin-contracts/contracts/interfaces/draft-IERC6093.sol.

  SECURITY.md line 24 additionally states that 'dependency checksum verification passed', which cannot have been true for the tree as committed (git status is clean and HEAD contains the same bytes as the working tree).

  Root cause: the recorded digests are those of the pristine upstream files at the pinned commits (I fetched OpenZeppelin dbb6104 and forge-std 77041d2 and the upstream digests equal the recorded ones), but the vendored copies were afterwards reformatted by forge fmt to the project's 100-column line length (e.g. ERC20.sol line 284 function _approve(address owner, address spender, uint256 value, bool emitEvent) internal virtual { was split across four lines; draft-IERC6093.sol line 121 error ERC1155InsufficientBalance(...) likewise).

  I confirmed every one of the 23 files is identical to its upstream original once whitespace is removed, so the compiled token is the genuine OpenZeppelin v5.0.2 ERC20 and there is no behavioural impact.

  The defect is that the project's own stated integrity check is broken and its review document reports a verification result that the tree does not reproduce, so a reviewer or launch operator following the README/DEPENDENCIES instructions gets a hard failure and has no shipped way to confirm the base contract is unmodified.

  Fix (either): restore the upstream bytes of the 23 files under lib/ (and exclude lib/ from forge fmt), or regenerate lib/SHA256SUMS from the committed bytes and reword DEPENDENCIES.md line 12 to say the files are reformatted but semantically identical, and correct SECURITY.md line 24.

  Note: lib/ and configuration are outside this task's write paths, so I changed nothing.

  Concretely for the production base contract: sha256sum lib/openzeppelin-contracts/contracts/token/ERC20/ERC20.sol prints 4a1db79b7b76a41b..., while lib/SHA256SUMS line 8 records 2d874da1c1478ed22a2d30dcf1a6ec0d09a13f897ca680d55fb49fbcc0e0c5b1 (which is the digest of the pristine upstream file at commit dbb6104). git show HEAD:lib/openzeppelin-contracts/contracts/token/ERC20/ERC20.sol | sha256sum gives the same 4a1db79b... so the mismatch is committed, not local. diff <(curl -sL https://raw.githubusercontent.com/OpenZeppelin/openzeppelin-contracts/dbb6104ce834628e473d2173bbc9d47f81a9eec3/contracts/token/ERC20/ERC20.sol) lib/openzeppelin-contracts/contracts/token/ERC20/ERC20.sol shows only the line-wrapping of the _approve(..., bool emitEvent) signature at line 284; stripping whitespace from both yields identical digests.

• lowVendored dependency checksums fail: lib/ was reformatted after lib/SHA256SUMS was recorded, so the documented integrity check fails and the 'unmodified'/'verification passed' claims are false (merged DEPENDENCIES.md:12

  All four specialists reported this one root cause; merged here into one finding, rated low. lib/SHA256SUMS holds the digests of the pristine upstream files (OpenZeppelin dbb6104c, forge-std 77041d2c). The vendored copies were later run through forge fmt (foundry.toml [fmt] line_length = 100), which rewrapped 23 of the 36 files.

  Two of those are the token's only production dependencies: lib/openzeppelin-contracts/contracts/token/ERC20/ERC20.sol, where the _approve(address,address,uint256,bool) signature is now split over lines 284-287, and draft-IERC6093.sol. DEPENDENCIES.md:12 says the files are unmodified and tells readers to verify them with sha256sum -c lib/SHA256SUMS. SECURITY.md:17 says 'vendored unmodified, and checksummed' and SECURITY.md:24 says 'dependency checksum verification passed'.

  None of this is true of the committed tree. There is no behavioural impact: with whitespace removed, both OZ files match upstream exactly, so PLEA compiles against genuine OZ v5.0.2 ERC20. The real problem is that the project's only provenance check is already failing, so a later real edit to ERC20.sol would look the same as this formatting noise.

  Fix: restore the byte-exact upstream files and exclude lib/ from forge fmt, or regenerate lib/SHA256SUMS from the committed bytes and correct the wording in DEPENDENCIES.md:12 and SECURITY.md:17/24.

  Running tr -d ' \n\t' over the upstream and vendored copies of ERC20.sol and draft-IERC6093.sol gives identical sha256 for each pair, so the change is whitespace only.
