Approved workflow

Implemented LaunchToken: “Dev Is A Robot” (NODEV), with exactly 1 billion tokens, 18 decimals, and no administrative powers.

Delivered tests, vendored dependencies, ABI export, and deployment documentation.

Validation passed with Solidity 0.8.26:

• forge build
• forge test: 37 passed, including fuzz and invariant checks
• forge fmt --check
• Empty-environment parallel test run

Manifest creation and independent review remain with their assigned stages.

the task produced no changes; the agent's last message was: Blocked by the execution environment: the required tool host /home/ubuntu/.local/bin/codex-code-mode-host is missing.

I couldn’t read the supplied files, create launch.json, or run forge build and forge test. No files were changed. The tool runtime needs to be restored before I can complete the assignment.

the task produced no changes; the agent's last message was: Blocked by the tool environment: both execution attempts failed because /home/ubuntu/.local/bin/codex-code-mode-host is missing.

No files changed. I couldn’t read the required inputs, write tests, or run forge build and forge test. Restore the execution tool and rerun this assignment.

the task produced no changes; the agent's last message was: The same environment failure persists: /home/ubuntu/.local/bin/codex-code-mode-host is missing. Both execution attempts failed before running commands.

No files changed. I couldn’t read the required inputs, create a verified launch.json, or run forge build and forge test. The tool host must be restored to complete this assignment.

Review complete. The findings file is written and valid, the tree has no stray files, and the only change in the working tree is the required .imd-findings.json.

Outcome: the economics of the token hold. No finding of medium or higher severity. One low finding outside the economics area, reported because it is concrete and reproducible.

What I verified in my area (Economic Security, Invariant, Flow Gap):

• LaunchToken adds nothing to OpenZeppelin ERC20. I fetched upstream v5.0.2 and diffed it: every vendored production file is byte-identical.
• The constructor mints exactly 10^27 minor units to the CREATE2 deployer, which is the factory. That matches the factory's SupplyMismatch gate and both protected tests. The large-literal lead from aderyn is a compile-time constant equal to the policy supply, not a defect.
• Conservation invariant: sum of balances equals total supply forever. No external mint, burn, pause, fee, hook, callback, delegatecall or selfdestruct path exists. The project's own model-based invariant test ran clean.
• The three entry points approve, transfer and transferFrom were traced through OZ _update and _spendAllowance. Overdraw and over-spend revert atomically, infinite allowance is untouched, and no value flows anywhere but between holders.
• The exported ABI in docs/abi matches the compiler output exactly. Build and all 37 tests pass.

The one finding (low): docs/DEPENDENCIES.md tells readers to verify vendored dependencies with a checksum file, and claims forge-std is unmodified. The check fails for 7 forge-std files. The recorded hashes equal the upstream v1.9.7 hashes, and the files in the tree differ from upstream only by forge fmt line wrapping. So the files were reformatted after the record was written. Test-only dependency, no effect on token behaviour, but the documented integrity procedure is broken. Fix is to restore the upstream bytes or regenerate the checksum file and reword the claim.

Coverage record: all three listed entry points marked holds, plus rows for the supply, conservation and no-fee invariants and the ABI export. The manifest row is unreached because no launch.json exists yet, which is expected at this stage.

Review complete. The findings file is written and only .imd-findings.json was created; no project files changed.

Result in the assigned area (Math Precision, Boundary, Numerical Gap): no defects. The token is OpenZeppelin ERC20 v5.0.2 with a constructor-only mint of a compile-time constant. There is no division, runtime multiplication, scaling, downcast, external call, payable path, or bytes decoding anywhere in the contract. The only arithmetic is OZ's _update, whose unchecked blocks are each guarded by the preceding balance or allowance check. The aderyn "large numeric literal" lead resolves to a constant-folded 1e27 and is not a defect.

What I verified by execution:

• Project suite: 37 tests pass, including 5 fuzz tests and 2 stateful invariants.
• The protected token floor, run locally with the expected supply and decimals set, passes 7 of 7.
• The exported ABI at docs/abi/LaunchToken.json is JSON-identical to the compiler's output.
• All six vendored OpenZeppelin files are byte-identical to upstream v5.0.2.

One low finding, outside my area. The documented integrity command in docs/DEPENDENCIES.md fails: 7 vendored forge-std files were reformatted after lib/checksums.sha256 was recorded. The recorded hashes match upstream v1.9.7, and the differences are whitespace-only, so the impact is limited to self-contradicting integrity evidence for a test-only dependency. The fix is to restore the files or regenerate the checksum list and drop the word "Unmodified".

Coverage: all three listed entry points plus the constructor are marked holds, with five additional invariant and guide-area rows, and one finding row for dependency integrity.

Created launch.json for the NODEV token-only launch, matching the accepted source and ABI.

Validation passed against the supplied schema and applicable refinements. forge build succeeded; forge test passed all 37 tests.

Only launch.json is changed outside permitted scratch artifacts.

Review complete. The findings file is written at .imd-findings.json and the tree is otherwise untouched.

Result: one low-severity finding, no defects in the token itself.

The deliverable is a two-line wrapper over OpenZeppelin v5.0.2 ERC20 that mints 10^27 units to its deployer. I traced all three state-changing entry points through the vendored implementation against the Execution Trace, Periphery and First Principles guides:

• approve, transfer, transferFrom all hold. Allowance is spent before the balance move and rolls back on any later revert, zero-address paths revert before any write, infinite allowance is never decremented, and no external calls or callbacks exist. The project's 36 unit and fuzz tests and the 128 by 64 invariant model all pass, and I confirmed them myself.
• Constructor and launch floor hold. I ran the protected token floor against the real creation code with the expected supply and decimals set, and all seven checks passed. The runtime has no DELEGATECALL, CALLCODE, SELFDESTRUCT, CALL, CREATE or PUSH0.
• ABI export is JSON-identical to the compiler's output, and the ABI documentation's semantics match the implementation.
• OpenZeppelin vendoring is byte-identical to the upstream v5.0.2 archive.

The finding is in the dependency provenance record. The documentation says forge-std is unmodified and tells the verifier to run the committed checksum file. That command exits non-zero with 7 failures because seven forge-std files were re-wrapped by the formatter after the hashes were recorded. I confirmed the differences are whitespace only, so nothing in test behaviour or deployed bytecode changes. The fix is either to restore the byte-exact upstream files or to regenerate the checksum file and correct the "unmodified" claim.

Not reached: there is no launch.json in the tree yet, which is expected at this stage. The README's handoff values match the canonical manifest guidance.

The review is complete. Findings and coverage are in .imd-findings.json at the repository root, and the working tree is otherwise unchanged.

Result: one low-severity finding, no access-control, trust-gap or asymmetry defects in the token.

The project is a single contract, a fixed-supply ERC-20 inheriting unmodified OpenZeppelin v5.0.2. What I verified in my area:

• Access control. The only privileged moment is the constructor minting the full supply to the deploying factory. There are no roles, modifiers, initializers, owner, pause, blocklist, mint, burn or upgrade paths. The compiled ABI has exactly nine functions, no receive or fallback, and the runtime bytecode contains no DELEGATECALL, CALLCODE or SELFDESTRUCT.
• Asymmetry. The approve/transferFrom and transfer/transferFrom pairs go through the same _update path. Allowance spend does not emit Approval and infinite allowances are not decremented, both standard OpenZeppelin v5 behavior and documented in the ABI notes.
• Trust gap. No in-token economics, so no actor can combine a permission with a formula to extract value. Zero-value transferFrom emitting a Transfer event from any address is standard EIP-20 and is documented, so I did not report it.
• Evidence. The build, all 37 project tests, formatting check, and both verifier floor suites (token and project, run under test/scratch with a CREATE2 factory stand-in) pass. The committed ABI JSON equals the compiler output. All five vendored OpenZeppelin files match upstream v5.0.2 byte for byte.

The one finding is a documentation trust claim that does not hold. The dependency doc tells the verifier to run sha256sum --check lib/checksums.sha256 and calls the forge-std files unmodified, but that command reports seven forge-std files as FAILED. I fetched upstream v1.9.7 and confirmed the recorded hashes are genuine and the delivered copies differ only in whitespace from a formatter pass. The test library is not tampered with, so severity is low, but a verifier following the documented step cannot tell that without redoing the comparison. The suggested fix is documentation-only since lib/ is not a contributor write path.

The static-analysis lead on the large numeric literal is a compile-time constant equal to 10^27 and is not a defect. No manifest exists yet, which is expected at this stage. The README handoff values match the approved workflow and launch guidance.

Added 11 adversarial tests covering authorization, revocation, rollback, and allowance boundaries. Expanded invariants to exercise 11 actions across 24,576 randomized calls.

Validation passed:

• forge build
• forge test: 48 passed, 0 failed, 0 skipped.

Only test/ files changed. No contract defects found.

The findings file is in place and is excluded from the tree by the harness's own ignore rule, which is expected for a review output. No tracked file changed. The review is complete; nothing further is needed.

Outcome: one finding kept, severity low, all three entry points hold. The report is written to .imd-findings.json in the repository root.

What I reproduced

• All four specialists reported the same defect, and it reproduces. Running the documented integrity command from docs/DEPENDENCIES.md exits non-zero with seven forge-std files reporting FAILED. I re-fetched those seven from the forge-std v1.9.7 tag: the recorded hashes match upstream exactly, and the committed copies differ from upstream only in whitespace. The four reports are merged into a single low finding, since forge-std is test-only and the record is a documentation and provenance contradiction rather than a code defect.
• The production dependency is clean. All OpenZeppelin v5.0.2 files, including ERC20.sol, are byte-identical to upstream.

What I verified myself

• forge build and forge fmt --check pass. The project suite passes 48 tests, including fuzz and stateful invariants.
• I ran both protected floor suites with the verifier's environment simulated, including the CREATE2 factory deployment and the expected supply of one billion tokens. All nine assertions pass.
• The exported ABI equals the compiler's output. An opcode scan of the compiled runtime, stepping over PUSH immediates, finds no DELEGATECALL, CALLCODE or SELFDESTRUCT.
• launch.json matches the accepted source and the manifest guidance: token name, symbol and decimals agree with the contract and brief, the contracts array is empty, the pool pairs with native ETH at fee 3000, tick spacing 60 and the standard initial price.
• The token itself is a single constructor mint over unmodified OpenZeppelin code with no owner, mint, burn, pause, fee or upgrade path, which is what the approved workflow asks for.

Coverage: approve, transfer and transferFrom are each marked holds with a one-line reason. Four extra rows cover the constructor, the absence of privileged paths, the manifest, and dependency integrity, the last pointing at the finding.

Suggested fix for the author: either restore the seven forge-std files byte-for-byte from the v1.9.7 archive already hashed in lib/DEPENDENCIES.txt, or regenerate lib/checksums.sha256 from the committed tree and change the forge-std row from "Unmodified" to "reformatted with forge fmt".

Implemented the frontend in web/ and static export in dist/.

• Build, typecheck, 17 interaction tests, and ABI/asset verification passed.
• Export is approximately 561 KB.
• Live pool has zero active liquidity; swaps remain disabled. No real transactions were sent.
• Evidence: VALIDATION.md. Design: DESIGN.md, placed within the permitted scope.

Git staging and commit were blocked because .git is read-only. All deliverable files remain ready for collection.
