I've written the BloxIMD token, its tests and the README, but I could not compile or run anything. Every shell command in this sandbox fails before it starts (apply-seccomp: write /proc/self/setgroups ... Permission denied). So forge build, forge test, forge fmt --check and the fuzz seed run are all untested, and nothing is committed: the files are in the working tree only. I checked the code by reading it, which is not a substitute for compiling.

What's in the tree:

• foundry.toml: pins solc 0.8.26, turns the optimizer on (200 runs) and sets bytecode_hash = "none". No ffi, file-system access or offline setting.
• src/BloxToken.sol: the contract is named BloxToken; name() returns "BloxIMD" and symbol() returns "BLOX", with 18 decimals. The constructor takes no arguments and mints all 1,000,000,000 tokens once to whoever deploys it (in the launch, the factory). There is no owner, mint, burn, pause, blacklist, fee or exemption list, so every transfer moves exactly the amount it names. It makes no outside calls and uses no libraries or DELEGATECALL/SELFDESTRUCT. Failures revert with named errors. An allowance set to the maximum value never goes down.
• test/BloxToken.t.sol (18 tests): checks the name, symbol and decimals, the one-time mint and its event, and that mint, pause, blacklist and similar admin calls don't exist. It also covers transfers, allowances, every failure path, and three fuzz tests that check the supply never changes and allowances are spent exactly.
• test/utils/MiniTest.sol: a small set of Foundry test helpers I wrote, because with no working shell I couldn't download or vendor forge-std. The project has no outside dependencies.
• README.md: token details, no constructor arguments, trust assumptions (no privileged role; the usual ERC-20 approval race), notes that the launch factory does the 10/80/10 split, an "After launch" section (nothing to configure), and how to build and test.
• .gitignore: ignores out/, cache/ and broadcast/.

I didn't write a deploy script or launch.json, as the launch rules say.

Still to do once a shell works: run forge build, forge test with FOUNDRY_FUZZ_SEED=0x910284aa5b352a572e5343bc844d0c0bc7cc2c4336910d7149e6fb097e0f5052, and forge fmt --check, fix any compile errors, then commit. The sandbox setting that blocks the shell is yours to change; I can't change it.

I found no defects in the math of src/BloxToken.sol. .imd-findings.json holds an empty findings list and a coverage row for each of the three entry points, all marked holds. The existing suite passes, 19 of 19. The protected tests weren't run: they read deployment settings that aren't set here.

• transfer and transferFrom balances: the subtraction skips overflow checks, but a balance check right before it means it can't go below zero. The addition can't overflow because all balances together never exceed the fixed supply of 1e27. Sending zero or sending to yourself both leave balances correct.
• transferFrom allowance: the allowance is checked before it is reduced. An allowance of type(uint256).max is deliberately treated as unlimited and never goes down. Spending exactly the full allowance leaves it at zero. If the transfer fails, the allowance change is undone with it.
• approve: it simply stores the new value, with no arithmetic. It rejects the zero address as spender.
• Supply: there is no mint or burn after deployment. The constructor mints exactly 1_000_000_000 * 10**18 to the deployer, which fits easily in a uint256. The analyzer's "large numeric literal" flag on line 12 is a style note, not a bug.

The token has no fees, rounding or price math, so most of the precision checklist doesn't apply here.

The manifest is written and verified. Only launch.json is new; nothing else in the tree changed.

What launch.json describes

• Token: contract BloxToken from the accepted source, name BloxIMD, symbol BLOX, 18 decimals, and an empty constructorArgs list because the accepted constructor takes no parameters.
• totalSupply: the constructor's single mint to msg.sender, written in minor units as a decimal string.
• contracts: an empty list, since the accepted tree contains no application contracts and the README confirms none accompany the token.
• pool and economics: copied exactly as the launch gives them. The pair is IMD, the fee is 12500, the tick spacing is 60, the initial price is the one-to-one provenance value, and economics matches the requester's object verbatim.
• notes: a short description of the token's fixed supply, lack of privileged roles, and whole-amount transfers, well under the 4000 character cap.

Checks run

• forge build compiled cleanly with the pinned solc 0.8.26.
• forge test with the verifier's fuzz seed passed all 19 tests in the accepted suite.
• A JSON check confirmed the manifest uses only schema keys, has string uint256 and address fields, numeric fee, tickSpacing and decimals, lowercase addresses, and the exact economics and pool objects.
• git status shows launch.json as the only new file.

The review is complete and the findings file is written at the repository root. No source files were changed, and the scratch tests were removed.

Result: no defects found in the assigned area. The findings file holds an empty list and six coverage rows, all holds.

What was covered

• Access Control. BloxToken has three state-changing entry points and no modifiers, roles, initializer, proxy, callbacks, receive or fallback. Each storage slot has exactly one writer path, so there is no weaker guard to exploit. The only privileged position is the deployer receiving the whole supply, which is the launch design.
• Asymmetry. approve and transferFrom were diffed as the approve/pull pair, and transfer against transferFrom. Both routes share the same internal transfer. The infinite-allowance sentinel is the sole branch and matches OpenZeppelin v5 behaviour. The owner gets no allowance bypass, which is standard.
• Trust Gap. The seams need a privileged actor or a paired economic formula. The contract has neither.
• Launch floor. The compiled runtime was scanned opcode by opcode with no CALL, DELEGATECALL, CALLCODE, STATICCALL or SELFDESTRUCT. The supply constant evaluates to exactly 1e27, so the aderyn large-literal lead is not a defect.

Checks run

• forge build, forge test with 19 project tests passing, and forge fmt --check.
• Eight scratch probes confirming self-transfer, zero-address sender rejection, zero-value transferFrom, finite versus infinite allowance, whole-supply round trips and the absence of receive or fallback.

Documented trust assumptions, not defects. The ERC-20 approve front-running race is inherent to the standard and is stated in the README. Slither and Mythril were not available and did not run.

The review is complete. No defects were found in the economics area, and the findings file records a clean result with full coverage.

Outcome: .imd-findings.json holds zero findings and six coverage rows, one for each of the three listed entry points plus three invariants. Nothing outside test/scratch/ and the findings file was touched.

What was checked, against the Senior Auditor's Mindset and the Economic Security, Invariant and Flow Gap guides:

• Economic Security. The token has no external dependency, oracle, callback or economic parameter. It is not fee-on-transfer, rebasing, pausable or blacklistable, returns a true boolean, and its sentinel-address paths all revert as ERC-20 and OpenZeppelin do. There is no value to extract and no shared capacity to starve.
• Invariant. The one conservation law, sum of balances equals the immutable supply of 1e27, has exactly one writer, the private transfer routine. The unchecked arithmetic is guarded by the balance check and bounded by the fixed supply. A scratch invariant run of 6,400 random transfers, approvals and transferFroms, including self-transfers, zero amounts, max and max-minus-one allowances and over-balance attempts, never broke it.
• Flow Gap. Factory to distributor, distributor to claimant, the single-sided seed and a buy and sell were simulated with a Uniswap v4 style sync, transfer and settle probe. Every balance delta equalled the amount named, so no launch flow arrives short and no exemption list is needed.
• Entry inventory and bytecode. The ABI exposes only the ERC-20 surface plus the supply constant. The constructor takes no arguments and mints to the deployer. The compiled runtime contains no DELEGATECALL, CALLCODE, SELFDESTRUCT, CREATE, CALL or STATICCALL.

Static-analysis leads. Slither reported nothing. Aderyn's low-severity large-literal note on line 12 is readability only and matches the stated supply exactly, so it was not reported.

Not reached. The protected launch test could not be run locally because the repository vendors no forge-std or v4-core, so the v4 settle path was checked with a local probe of the same accounting rather than the real PoolManager. The documented ERC-20 approval race is standard behaviour and was left as a trust note, not a finding.

The review is complete and .imd-findings.json holds the result: no substantiated defects and nine coverage rows. The working tree is otherwise unchanged. Git status shows only the findings file, which is gitignored output, so nothing else was touched.

What I reviewed. The token at src/BloxToken.sol is a 76-line fixed-supply ERC-20 with no owner, no external calls, no fee and no fallback. I applied the Senior Auditor's Mindset and the three assigned guides, Execution Trace, Periphery and First Principles, to each of its three state-changing entry points, and confirmed every conclusion with scratch Foundry tests that I ran and then removed.

What holds, and how I checked it:

• transfer and transferFrom move exactly the amount named. Self-transfer re-reads storage after the debit, so the balance is unchanged. The zero-sender sentinel is reachable only through transferFrom with value zero and reverts. A transferFrom that fails on balance rolls the allowance decrement back.
• approve writes only the caller's own allowance. The standard approve race is inherent to ERC-20 and is documented in the README, so I did not report it.
• Conservation. A fuzzed sequence of eight transfers among four parties always sums to the full supply, so the unchecked addition cannot overflow.
• Launch flows. Factory to distributor, distributor to claimant, pool seed, buy and sell each arrive whole in an emulation, so the protected test's balance-delta settlement will match.
• Bytecode and ABI. The compiled ABI has exactly the three listed entry points, no receive, no fallback and no constructor arguments. The deployed bytecode contains no DELEGATECALL, CALLCODE, SELFDESTRUCT, CALL, STATICCALL or CREATE.
• Periphery. The test helper in test/utils/MiniTest.sol is correct for every range the tests use and is never deployed.

Static analysis leads. Slither reported nothing. Aderyn's large-literal note at line 12 evaluates to exactly the manifest supply, so it is not a defect.

Not reachable in this budget. The real Uniswap v4 pool seed and swap could not be run locally because v4-core is not vendored. The emulation covers the token's side of those flows, and the protected test will exercise the rest.

Work is complete and verified. Here is the recap.

Outcome: forge test passes with the verifier's fuzz seed: 64 tests across 3 suites, 0 failures. I found no defect in src/BloxToken.sol, so there is no .imd-findings.json to file. The token is a plain fixed-supply ERC-20 with no admin surface, exact-amount transfers, and correct revert paths.

What I added, all under test/:

• test/BloxTokenEdges.t.sol: 44 adversarial unit and fuzz tests. They cover deployment from a contract in one call so the mint lands on the factory, the constructor emitting exactly one log, ether and unknown selectors being rejected, sixteen more privileged selectors that must not exist, and the deployer having no power over a holder. Boundaries covered include the whole supply, supply plus one, the type maximum, one wei twice, self-transfer above balance, the zero address as sender via prank, as receiver, as spender and as approver, allowance exactly equal to the amount, allowance one below the infinite sentinel, infinite allowance still bounded by balance, the allowance check preceding the balance check, and a reverted transferFrom leaving the allowance intact. Fuzz tests run at 1000 runs via inline config.
• test/BloxTokenInvariant.t.sol: a handler with six actors, clamped and raw entry points, and a ghost ledger that predicts every call's outcome including the exact revert payload. Seven invariants check fixed supply, sum of all balances equals supply, every balance and allowance matches the ledger, the zero address holds nothing, and the token agrees with the model on every call. It runs 256 sequences of depth 64 with fail-on-revert enabled through inline config.
• test/utils/MiniTest.sol: additive only. A few more cheatcodes and assertion helpers the new files need. The existing 19 tests and the earlier contributor's file are untouched.

Grounding: in scratch I ran the invariant suite against two mutant tokens, one burning a wei per transfer and one never decrementing a finite allowance. Each was caught by the invariants that should catch it, and the unrelated invariants stayed green. Scratch files are not part of the deliverable.

One note for the record: the invariant suite takes about 32 seconds locally, which is the largest cost in the run.

I found no defects in BloxToken. .imd-findings.json has an empty findings list and a coverage row for each of the three entry points, all marked holds.

What I checked:

• src/BloxToken.sol: The constructor mints exactly 1,000,000,000 × 10^18 to the deployer. totalSupply can't be changed after deployment. The contract has no owner, mint, burn, pause, blacklist or fee, and no delegatecall or selfdestruct.
• transfer: It moves exactly the amount it names. Sending to the zero address or sending more than the balance reverts. Sending tokens to yourself leaves the balance unchanged. The unchecked addition can't overflow because the supply is fixed. Since there is no fee, the factory's payment to the distributor, the pool seed and swaps all arrive in full.
• transferFrom: It checks the allowance before reducing it, and a maximum allowance is never reduced. If the transfer itself fails, the allowance reduction is undone too.
• approve: It refuses the zero address for either side, sets the allowance and emits the event.
• launch.json: It uses only schema fields, and the contract name is valid. The constructor arguments are empty to match the argument-less constructor. Supply and decimals match the code, and addresses are lowercase.

Specialists and tools: none of the four specialists or the independent tester reported anything, so there was nothing to reproduce or merge. Slither reported nothing. Aderyn's "large numeric literal" note on line 12 points at 1_000_000_000 * 10 ** 18, which is the intended supply, so it isn't a defect.

Tests: the project's own suite passes, 64 tests with 0 failures. I did not run the protected launch tests: they need the launch's environment settings and source files that aren't in this tree. I checked by hand the properties they test (supply minted to the factory, decimals, distributor transfers arriving whole) and didn't try the pool seed or swap they also exercise. Nothing in the repository was modified.
