Implemented MemecoinCemetery.sol with the required lifecycle, token checks, ETH rejection, and NatSpec.

forge build succeeds. All 32 scratch tests pass, including fuzz and deployment checks. No configuration or dependencies changed.

Explorer source verification remains pending deployment.

Added test/MemecoinCemetery.t.sol with lifecycle, failure-path, fuzz, and invariant coverage.

Offline verification passed: forge build and all 36 tests, including 16,384 invariant calls. No reproducible defects found. Only the allowed deliverable file changed.

Created launch.json listing only MemecoinCemetery with empty constructor arguments.

Validated the manifest structure and constructor ABI. forge build succeeded; all 36 tests passed. Only launch.json is a submission change.

The review is complete. No tracked files were changed, and .imd-findings.json holds the result.

Verdict: no defects found that warrant a revision. The implementation matches the brief, and the test suite covers every acceptance item. I traced all three state-changing entry points and re-ran the full suite, including the stateful invariant campaign, plus scratch probes of my own.

What I checked and found correct:

• dig enforces the 140-byte limit, one record per token, the exact 30-day cooldown boundary after a resurrection, a code-size check, and both token reads via STATICCALL. State writes are atomic on revert.
• itLives uses a ceiling threshold equal to balance * 1000 >= supply without overflow at maximum supply. It rejects at and after the deadline, deletes the record, and starts the cooldown. Token callbacks cannot mutate cemetery state.
• seal does not read the token, so a broken token cannot block burial. Buried graves are permanent and counted exactly once.
• No ETH path: the ABI has no receive, fallback, or payable function. The runtime is 5247 bytes with no DELEGATECALL, CALLCODE, or SELFDESTRUCT, so the protected deployment test should pass.
• The static-analysis leads (literal 1000, unchecked return from the validating read in dig) are style only, not defects.

Three info-level observations are recorded with reproductions, none blocking:

1. A token that returns empty or short data from totalSupply or balanceOf reverts with zero bytes of revert data rather than the documented custom error. The try/catch does not cover ABI decoding failures. The spec requirement that such a token cannot be dug still holds.
2. A momentary 0.1% balance, such as a flash swap returned in the same transaction, is enough to cancel a wake. The brief explicitly asks for balances checked at call time, so this is a scope note, not a defect.
3. When totalSupply reports zero, no account can object regardless of its balance. This is documented in the NatSpec and is a reasonable reading of the brief, but the tests only cover the zero-balance case.

One configuration note outside the author's scope: there is no foundry.toml, so the compiled metadata uses the default ipfs bytecode hash rather than the recommended none. That is a config-file concern for whoever owns the launch policy, not a code finding.
