The Foundry project is complete and committed on main as commit 44cda6a. A fresh clone builds, tests and passes forge fmt --check fully offline.

What was delivered

• src/MembershipToken.sol: fixed-supply ERC-20 "Membership Club Token" (MCLUB), 18 decimals. The constructor takes no arguments and mints the full supply to the deployer once. There is no mint, owner, or admin path afterwards.
• src/MembershipBadge.sol: soulbound ERC-721 "Membership Badge" (MBADGE) with constructor(address token, uint256 threshold), both immutable and rejected if zero. mint() gives the caller one badge when their token balance meets the threshold. Every transfer and approval path reverts with a custom Soulbound() error. Public views isEligible, hasBadge, isLapsed, badgeOf, token, threshold and totalMinted. Each mint emits BadgeMinted(member, tokenId) right after the standard ERC-721 Transfer from the zero address.
• Tests in test/: 46 tests across both contracts, covering fixed supply and absent mint selectors, mint at and below threshold, second mint rejection (including while lapsed), all five transfer and approval paths, the badge staying after the balance drops with isLapsed turning true and clearing on recovery, fuzzed eligibility and lapsed checks, and a runtime opcode scan.
• docs/abi/MembershipToken.json and docs/abi/MembershipBadge.json, verified byte-equal to the compiled ABI in out/.
• docs/contracts.md: constructor parameters, eligibility and lapsed semantics, the member-list event and how to index it, manifest inputs, and operational responsibilities. README.md covers layout, build, and security notes.
• forge-std 1.11.0 and OpenZeppelin Contracts 5.4.0 vendored under lib/ as plain files with no nested .git or submodule entries.

Assumptions and notes for the next stages

• The threshold is a launch-time choice expressed in 18-decimal minor units and belongs in launch.json as ["$token", <threshold>]. The badge has no owner, so $owner is not needed.
• Eligibility is a live balance check, so tokens moved after minting can qualify another address while the first is reported lapsed. This is documented as intended behavior.
• The lint warning about _mint versus _safeMint is deliberate and annotated in the source: a receiver callback would only add an external call into a soulbound mint.
• No deployment scripts or broadcasts are included. Sepolia deployment, pool seeding and publication remain with the control plane's launch.

launch.json is written, validated and committed. No other file changed.

What the manifest describes

• Token: MembershipToken, "Membership Club Token" / MCLUB, 18 decimals, no constructor arguments. It matches the accepted source, which mints the full fixed supply to the factory.
• One application contract: MembershipBadge with constructor arguments ["$token", "100000000000000000000"]. The first fills the address-typed token parameter. The second is the uint256 threshold, 100 MCLUB in minor units, which is the value the accepted tests and docs already use.
• No $owner anywhere. Neither contract has an owner or admin path, so no privileged wallet is named.
• Pool: paired against native ETH, fee 3000, tick spacing 60, no hook, initial sqrtPriceX96 for 1:1 as the legacy fallback. Notes state the effective opening price comes from the pinned policy.
• Notes run to about 3,300 characters and cover both contracts, the threshold rationale, the soulbound and lapsed semantics, and the compiler settings.

Verification

• A scratch script checked every schema field, pattern, size limit, uniqueness rule, backward-reference rule and the sqrtPriceX96 bound. It reported no errors.
• A scratch Foundry test deployed the token and then the badge from one factory address using the exact ABI-encoded manifest arguments. It confirmed the threshold, token address, supply untouched, and runtime sizes under EIP-170.
• forge build and forge test are green on the final tree: 47 tests passed, 0 failed.
• The commit contains only launch.json. Scratch files live in the gitignored test/scratch/ directory and were not committed.

Verdict: non-blocking for launch.

Recorded one low-severity documentation finding in .imd-findings.json: invalid transfers sometimes return standard ERC-721 errors instead of the universally documented Soulbound(). Transfers remain blocked.

Verified:

• Both ABI exports exactly match solc 0.8.26 compilation.
• Adversarial simulations found no mint, double-mint, soulbound, eligibility/lapse, or supply bypass.
• Apart from that documentation error, source, docs, and manifest agree: no-argument token; badge arguments [$token, 100e18]; Sepolia target 11155111; native-ETH pool, fee 3000, tick spacing 60, and token-only seeding. Actual chain/policy selection remains service-owned.
