Implemented Swarm and BurnTracker with the initial mint, 1% transfer burn rounded down in base units, cumulative burn tracking, and no admin privileges or external dependencies.

Documentation and gas measurements are embedded in the contract comments. Tests remain in test/scratch/.

• forge build: passed.
• forge test: all 34 scratch tests passed, including fuzz tests.
• Protected checks: 7/8 passed. The remaining check requires fee-free transfers and unchanged supply, directly contradicting the requested burn behavior.

Only the two permitted source files are deliverable changes.

Added 51 passing tests, including five fuzz tests and failure-path coverage. README notes and measured gas figures are embedded in the permitted test files.

forge build and forge test --gas-report pass.

Reported the launch incompatibility in .imd-findings.json: Swarm’s required burn conflicts with protected checks requiring full receipt and unchanged supply.

The response file is in place and excluded from git by the harness's own rules, as intended. The work is complete.

Finding reproduced and fixed. Running the supplied protected token suite against Swarm's creation code failed exactly as reported: the recipient received 99% and total supply dropped. That is Swarm's required burn, so Swarm cannot be the launch token.

What changed (only src/Swarm.sol, additive, 79 lines):

• Added a second contract, SwarmLaunchToken, in the same file, since it is the only permitted path. It is a plain fixed-supply ERC-20 with no constructor arguments, 18 decimals, and exactly 10^27 minor units minted to the deployer. It has no mint, owner, pause, upgrade, or initialize path and no forbidden opcodes.
• Extended the README comment on Swarm to state that Swarm is not the launch token and describe the launch layout: launch token first, then Swarm and BurnTracker as application contracts. The Swarm and BurnTracker code itself is untouched.

Verification in the scratch project with Forge 1.8.3 and solc 0.8.26:

• Protected token suite against the new launch token: 6 of 6 pass, including the transfer check that previously failed.
• Scratch mirror of the project floor, deploying launch token, Swarm, then BurnTracker through a CREATE2 factory probe: launch supply and factory balance unchanged after each constructor, both application runtimes under the size limit with no forbidden opcodes.
• Five launch token unit tests pass, including a 256-run fuzz on exact-amount transfers.
• forge build succeeds.

Answered the finding as fixed in .imd-responses.json at the repository root.

One point for the manifest author. Swarm mints its 1,000,000 SWORM to its constructor caller, as the task specifies. Under the factory that caller is the factory itself, which cannot move them. I left this alone because the task states it explicitly and it was not part of the finding.

Added 14 regression tests for launch-token behavior, failure paths, and BurnTracker integration. Updated the embedded README and gas report.

forge build, forge test, and gas reporting succeed. All 65 tests pass with Solidity 0.8.26 and 0.8.30.

Recorded a compiler-dependent metadata scan issue in .imd-findings.json: the reproduced protected scan rejects 0.8.30 artifacts; 0.8.26 passes.

Created launch.json matching the accepted contracts and constructor order. Only the manifest is submitted.

Schema and ABI checks passed; forge build succeeded; all 65 tests passed with a gas report.

Existing limitation: Solidity 0.8.30 metadata triggers protected opcode checks for SwarmLaunchToken and BurnTracker. This cannot be fixed within the manifest-only scope.

Recorded one high-severity finding in .imd-findings.json: factory deployment strands the entire SWORM supply while launching non-burning SWLT.

Reproduced locally with Anvil. All 65 existing tests pass. Contracts and tests remain unchanged.

The responses file is present and is deliberately excluded from git by the harness's own exclude rules, so the harness picks it up from the working tree. Everything is in place.

Outcome: the high finding reproduced and is fixed in src/Swarm.sol. The low finding is disputed because it lives in build configuration I cannot touch. Both answers are in .imd-responses.json.

What reproduced. Deploying the launch token, Swarm and BurnTracker through the exact ProjectDeploymentProbe left all 1,000,000 SWORM with the probe. No transfer or allowance path existed, so both reverts the reviewer described occurred.

What changed. One new application contract, SwarmConverter, appended to Swarm.sol. Swarm, SwarmLaunchToken and BurnTracker code is untouched.

• Deploys its own children. The converter's constructor creates Swarm, so the converter is the constructor caller that receives the supply, then creates BurnTracker bound to it. It reverts unless the launch token's supply is exactly 1000 times the SWORM supply.
• Permissionless two-way exchange. Anyone can lock launch tokens to receive SWORM at 1000:1, or return SWORM to unlock launch tokens at the same rate on what actually arrives after the 1 percent burn.
• No privileges. No owner, withdraw, pause, rescue or ETH acceptance. The documented invariant is that launch tokens held always back every SWORM outside the converter, so redemption cannot run short.
• Launch layout in the natspec README now says: launch token SwarmLaunchToken, one application contract SwarmConverter with argument $token, and never deploy Swarm directly from the factory. The manifest node must follow this, since I cannot edit launch.json.

Verification. In a scratch workspace mirroring the harness config, 19 tests pass. They cover the probe-based launch flow, exact burn and backing math, full-supply conversion, rejects, admin-surface probes, a 256-run fuzz round trip, and both protected suites with computed CREATE2 addresses. forge build from the repo root succeeds.

Low finding. With bytecode_hash set to none, the documented policy setting, the opcode scan passes deterministically on all four contracts under solc 0.8.26 and 0.8.30, optimizer on and off. With IPFS metadata the result is random per digest and flips with every edit and with forge fmt, so I made no source change for it and explained this in the response.

Updated only the two permitted test files, adding 15 tests for converter accounting, failure rollback, rounding, donations, and BurnTracker integration. Refreshed the embedded README and gas report.

Verification: forge build succeeds; all 80 tests pass offline with Solidity 0.8.26 and 0.8.30. All eight protected checks also pass in a local scratch replay.

Updated launch.json to deploy SwarmConverter("$token"), which creates Swarm and BurnTracker. Notes now match the accepted implementation.

Schema constraints and constructor ABIs checked. forge build succeeded; forge test --gas-report passed all 80 tests. Only launch.json changed outside permitted scratch artifacts.

Confirmed the prior high-severity stranded-supply finding is fixed. All 37 targeted tests passed, including factory deployment, conversion/redemption, and randomized accounting checks. No new reproducible defects found.

Wrote {"findings":[]} to .imd-findings.json. Repository contracts and tests remain unchanged.
