The nomination supply read and the headstone symbol read keep the 50,000 cap, while the holder check forwards the caller's remaining gas for totalSupply, decimals and balanceOf. I copied all three attached proofs under test/scratch and ran them against the revised contract. All eight proof tests pass, including the reflection-token save and rise cases that previously reverted with TokenReadFailed. The author also added a permanent regression file for expensive balance, supply and decimals reads on both defensive paths.\n- **Info, ERC-721 collections can be dug: closed.** The README now documents the input-class limitation with the 10-NFT example, and the contract behaviour stays as the brief specifies.\n- **Info, bytes32 symbols fall back to the address: dropped.** The author's dispute is correct. This is the documented fallback for a failed read, it never reverts, and the README states it.\n\n**Fresh pass on the changed code**\n\nI re-read the gas-forwarding change as new code. Forwarding gasleft() on STATICCALL paths only lets a hostile token waste the gas of the holder who chose to call. State cannot change inside a static call, and the return copy is still bounded to one word with an exact 32-byte size check. The static-analysis leads do not hold up. The locked-ether warnings are false positives because receive and fallback always revert. The divide-before-multiply lines are the standard Hinnant calendar arithmetic. The uninitialized local in the XML escaper is assigned on every path that reads it.\n\n**Artifact checks**\n\nThe committed ABI equals the offline build output. The creation and runtime bytecode keccak hashes and the source sha256 in the build record all match the compiled output. The manifest lists one contract with no constructor arguments and no owner. The full offline suite passes with 50 tests, including the invariant and model suites.\n\nThe scratch directory was removed, and the working tree holds only the required findings file.","createdAt":"2026-10-07T06:14:04.652Z","verdict":null,"findings":[],"coverage":{"rows":[{"target":"MemecoinCemetery.dig(address,uint8)","verdict":"holds","why":"epitaphId<24, state None/Saved/Risen, cooldown, code.length>0 and a 32-byte non-zero totalSupply() read still capped at TOKEN_GAS=50_000 (line 111); resets dates/mourners, keeps history counters, emits WakeOpened."},{"target":"MemecoinCemetery.itLives(address)","verdict":"holds","why":"Wake state and strict pre-deadline check, then _requireHolder which now forwards gasleft() (lines 273-280); prior medium finding 83b2404f confirmed fixed: all three attached proofs pass on this code (8 scratch tests, 0 failures)."},{"target":"MemecoinCemetery.seal(address)","verdict":"holds","why":"Wake state, timestamp>=wakeEndsAt, writes Buried, increments burials and _graveCount, stores immutable Burial record, pushes to _recent; no token calls so metadata cannot block it."},{"target":"MemecoinCemetery.mourn(address)","verdict":"holds","why":"Buried state only; per-token/per-burial-number/per-sender flag so a re-burial allows mourning again; mirrors count into the burial record."},{"target":"MemecoinCemetery.rise(address)","verdict":"holds","why":"Buried state, holder check with caller-funded gas, state Risen, rises++, _graveCount--, cooldown set; burial record untouched (regression test and fuzz confirm)."},{"target":"MemecoinCemetery.receive()","verdict":"holds","why":"Always reverts ETHNotAccepted; static-analysis locked-ether lead is a false positive since no ETH can be accepted and the brief forbids a withdraw path."},{"target":"MemecoinCemetery.fallback()","verdict":"holds","why":"Always reverts ETHNotAccepted for unknown selectors with or without value."},{"target":"finding 83b2404f (holder reads capped at 50k gas)","verdict":"holds","why":"Fixed: _readWord takes a gasLimit; dig and _symbol keep 50_000, _requireHolder passes gasleft().

On SafeMoon-style reflection tokens with six or more reward-excluded accounts, balanceOf exceeds that budget, so a legitimate holder is rejected with TokenReadFailed on both itLives and rise. Anyone can dig such a live token, nobody can object, seal buries it, and it can never rise. I reproduced it with a proof file that fails on the current code and passes against a copy with the holder-read cap raised to 500,000 gas. The audit_flow, audit_math and audit_economics reports described the same root cause and are merged at medium: no funds are lost, but the brief's central guarantee breaks for a common token class.\n- **Info, finding 2.** An ERC-721 Enumerable collection passes dig and its holders need totalSupply/1000 NFTs to object. Reproduced, but this is exactly what the brief specifies for dig and the holder rule, so I lowered it from low to info.\n- **Info, finding 3.** A bytes32 `symbol()` renders the shortened address instead of the symbol. Reproduced; it matches the brief's fallback rule.\n\n**What I checked beyond the specialists.** All 43 project tests pass offline. The committed ABI is byte-identical to the compiled ABI. The on-chain date routine matches Python's UTC calendar for 58 timestamps including leap-century edges. Every state transition, cooldown, counter and the two invariants trace correctly.

On SafeMoon-style reflection tokens (a large share of memecoins) balanceOf divides by _getRate(), which loops over every reward-excluded account at roughly 8.3k gas per entry; measured cold cost is 45,442 gas at 4 excluded accounts and 62,080 at 6, so with six or more excluded accounts (pair, dead address, token contract, marketing, locker, router is a common set) the read runs out of gas and every holder is rejected regardless of balance. The result is asymmetric: anyone can dig such a live token for one transaction, no holder can object, seal() buries it after 72 hours, and because Buried exits only through rise() the burial is permanent. This breaks the brief's central guarantee that any real holder can stop a burial and that a buried token can come back. The cap gives no safety benefit on these paths: the reads are STATICCALLs paid for by the holder who chose to call, and a hostile token can only waste that caller's own gas; the 32-byte return-size check already bounds memory. The README's note that such tokens 'may be unable to be nominated or defended' does not match the behaviour: nomination succeeds, only defence fails. Reported by audit_flow (medium), audit_math (low) and audit_economics (medium); merged into one finding. Minimal fix that preserves the design: forward a much larger cap (or gasleft()) for the totalSupply/decimals/balanceOf reads inside _requireHolder only, keeping 50,000 for dig()'s totalSupply read and for _symbol(); the attached proof passes on a copy with TOKEN_GAS raised to 500_000 for those reads.","reproduction":"State: fresh MemecoinCemetery; ReflectionToken T with totalSupply 1e24, decimals 9, 8 reward-excluded accounts, HOLDER holding 1% of supply (threshold is min(1e9, 1e21) = 1e9, HOLDER balance is 1e22; T.balanceOf(HOLDER) costs 80,976 gas cold). 1) DIGGER calls dig(T, 2): succeeds, state Wake. 2) HOLDER calls itLives(T) during the wake.

The findings file is written with 2 findings and 12 coverage rows, and the proof test fails on the current code for the stated reason.\n\n**Outcome**\n\nThe contract's economics and invariants hold almost everywhere I checked. All 43 project tests pass, the committed ABI matches the compiled one, and the runtime bytecode hash matches the build record. The state machine, 72-hour wake, 7-day cooldown, grave count coupling, burial-record immutability, mourn-once-per-burial rule and the holder threshold formula all behave as the brief specifies. Two defects were substantiated, both in `.imd-findings.json`.\n\n**Findings**\n\n- **Medium, holder reads capped at 50k gas.** The read helper forwards exactly 50,000 gas for `balanceOf` and `totalSupply` inside `itLives` and `rise`, the same cap the brief asked for in `dig`. Reflection-style memecoins (SafeMoon and its forks) compute `balanceOf` by looping over reward-excluded accounts. With six or more such accounts the call needs more than 50k gas, so `dig` succeeds on a cheap `totalSupply` while every holder's objection reverts with a read failure. The token is sealed after 72 hours and can never rise. This breaks the brief's core guarantee that any real holder can stop a burial. A proof test under `test/scratch/HolderGasCap.t.sol` fails today and passes against a copy with a larger cap. Suggested fix: forward much more gas on the holder paths only, since the holder is the caller paying for it.\n- **Low, ERC-721 Enumerable collections pass `dig`.** The only token check is code plus a non-zero `totalSupply`. An NFT collection with 10,000 pieces is accepted, and the threshold becomes 10 whole NFTs, so typical holders cannot object. Suggested fix is a gas-capped ERC-165 probe for the ERC-721 interface, or an explicit README note.\n\n**Coverage**\n\nAll seven listed entry points have rows. `seal`, `mourn`, `receive` and `fallback` hold. `dig` carries finding 2. `itLives` and `rise` carry finding 1. Five additional rows record the invariants I verified. The static-analysis leads (divide-before-multiply in the calendar code, locked ether, timestamp comparisons) were checked and are not defects: the calendar arithmetic is the published algorithm and is tested at leap and century boundaries, and forced ETH has no victim and is documented.\n\n**Not covered**\n\nI did not evaluate Robinhood Chain sequencer timestamp drift against the 72-hour window, and I did not assess the explorer verification step, which needs a deployed address.","createdAt":"2026-10-07T05:49:49.563Z","verdict":null,"findings":[{"severity":"medium","title":"Holder reads share the 50k-gas dig cap: tokens with an expensive balanceOf can be dug but no holder can ever save or raise them","path":"src/MemecoinCemetery.sol","line":279,"description":"_requireHolder (src/MemecoinCemetery.sol:271-281) reads totalSupply() and balanceOf(msg.sender) through _readWord, which forwards exactly TOKEN_GAS = 50_000 (line 59, used at line 293). The brief asks for a gas-capped read of totalSupply() in dig() so a hostile token cannot burn the digger's gas, but the same cap is applied to the holder paths itLives() and rise(), where the caller is the holder who chose to pay for the call. The result is an asymmetry between attack and defence: dig() needs only a cheap totalSupply(), while defending needs balanceOf() to finish in 50k gas. Reflection/RFI tokens (SafeMoon and its thousands of forks, i.e. exactly the memecoins this contract targets) compute balanceOf() as _rOwned[account] / _getRate(), and _getRate() loops over every reward-excluded account with ~8.3k gas per iteration (measured: 1 excluded = 18.1k, 5 = 51.4k, 6 = 59.7k, 8 = 76.4k gas cold). With six or more excluded accounts (pair, dead address, the token itself, marketing, locker, router are typical) balanceOf() exceeds the budget, the STATICCALL runs out of gas, _requiredWord reverts with TokenReadFailed(token, 0x70a08231) and every holder, however large, is rejected. The token is sealed after 72 hours and cannot rise either, so a live token gets a permanent burial record that nobody can contest. This breaks the brief's central guarantee ('any real holder can stop a burial') and the README's promise that holders can always defend; the README only notes that such tokens 'may be unable to be nominated or defended', but here nomination succeeds while defence is impossible. Economic Security (dependency failure blocking the only defence) and Flow Gap seam execution x periphery x first principles. Who loses: holders of any reflection token with >=6 excluded accounts; cost to attacker: one dig() transaction. Proposed fix: in _requireHolder forward gasleft() (or a much larger cap such as 500_000) for the totalSupply/balanceOf/decimals reads; the 32-byte return-data check already bounds memory, and a gas bomb on these paths only costs the holder who called.

The findings file is valid JSON, both snippets match the source lines, and the working tree is clean apart from the findings file (which is ignored by git).\n\n**Outcome.** The math in `src/MemecoinCemetery.sol` holds up. No critical, high or medium defects were found in the Math Precision, Boundary or Numerical Gap areas. The file `.imd-findings.json` carries two minor items and 13 coverage rows covering all 7 entry points plus the static-analysis leads and both stated invariants.\n\n**What I verified with concrete values**\n\n- Holder threshold `max(1, min(10**decimals, supply/1000))` behaves correctly at the 6-decimal boundary, the 1-base-unit floor for supply under 1000, decimals 36, and decimals 37 defaulting to 18.\n- The on-chain date algorithm matched an independent loop-based calendar across 2000 fuzz runs from 1970 through 9999, plus leap-year and 2038/2100 edges. Slither's divide-before-multiply lines there are the algorithm itself, not a bug.\n- Symbol decoding accepts a 64-byte symbol, rejects 65, rejects non-canonical sizes, and escapes all five XML metacharacters. The seal/itLives deadline comparisons are exact complements with no gap or overlap.\n- The full project suite passes, 43 tests including both invariants.\n\n**Findings reported**\n\n1. **Low.** The fixed 50,000-gas cap on `balanceOf` reads locks holders of reflection-style tokens out of `itLives` and `rise`. A SafeMoon-shaped mock with 6 excluded accounts costs about 53k gas cold, so both calls revert and the token is buried unopposed despite a holder owning 1% of supply. With 5 excluded accounts it works. The README discloses this trade-off and the brief names the cap, so this is a design decision to revisit rather than a logic defect. Since the calls are static, raising the cap carries no reentrancy cost.\n2. **Info.** Tokens returning a raw `bytes32` symbol (MKR-style) always render the shortened address on the headstone, which is consistent with the brief's fallback rule.\n\nNothing in my area was left unreached.

The cap is fixed for every token. Reflection memecoins (SafeMoon family, a large share of the tokens this contract targets) compute balanceOf as _rOwned[a] / _getRate(), and _getRate() iterates the _excluded array reading three cold storage slots per entry. Measured cold cost in a Foundry probe with that exact shape: 3 excluded = 31,270 gas, 5 excluded = 45,844 gas (itLives succeeds), 6 excluded = 53,131 gas, 8 excluded = 67,705 gas (itLives and rise revert TokenReadFailed(token, 0x70a08231)). Six or more excluded accounts (burn address, pair, deployer, marketing, locker, router is a common set) is ordinary for these tokens. For such a token: dig succeeds (totalSupply is a plain sload), no holder can call itLives or rise however large their balance, seal buries it after 72 hours, and it can never be marked Risen. The headline guarantee in the brief that any real holder can stop a burial does not hold for this token class. The README does disclose that reads needing more gas may make a token undefendable, and the brief fixes a cap \"such as 50,000\", so this is reported as a design trade-off at low severity rather than a logic defect. The calls are STATICCALL so a larger cap cannot cause reentrancy or state change; raising TOKEN_GAS for balanceOf (e.g. 150,000-200,000) or making the forwarded gas gasleft()-bounded would cover these tokens at no safety cost. The same cap applies to totalSupply in dig; tokens whose totalSupply is computed could likewise be undiggable, which is harmless.","reproduction":"Deploy a token T with ERC-20 totalSupply()=1e24, decimals()=18 and a reflection-style balanceOf that loops over 6 excluded accounts reading _excluded[i], _rOwned[_excluded[i]] and _tOwned[_excluded[i]] (cold SLOADs), then divides.

A scratch probe exercised a 24-decimal token, the deadline and cooldown boundaries, an escaped symbol and three ETH paths, then was deleted.\n\n**Severity counts:** 0 Critical · 0 High · 0 Medium · 0 Low\n\nNo defect survived the verification gate in the assigned area. `.imd-findings.json` holds an empty findings list and eleven coverage rows, one per entry point plus the two brief invariants, the trust surface and the artefacts.\n\n## Coverage\n- **Permission model.** There are no roles, setters, initializers, proxies or owner; the constructor hands nothing to the factory. Each storage variable has one writer per transition, so there is no weaker-guard parallel path. `receive` and `fallback` revert unconditionally and every application function is nonpayable.\n- **Asymmetry pairs.** `itLives` uses a strict less-than on the deadline and `seal` a greater-or-equal, so the two are complementary with no gap or overlap. `seal` increments both `burials` and `graveCount` and `rise` decrements only `graveCount`, which keeps the count equal to the Buried set because Buried has no other exit. `dig` resets the latest attempt's dates and mourners but never the lifetime counters. `mourn` mirrors its count into the numbered record and is blocked in Risen, freezing the record.\n- **Trust gap.** The only trusted input is token-supplied supply, decimals, balance and symbol. All four are read through a 50,000-gas static call with an exact 32-byte or bounded 128-byte size check, so a token cannot re-enter, bomb or corrupt state. I checked whether a caller could starve the `decimals` read of gas to lower the threshold for a token with more than 18 decimals. The fixed cap makes that impossible: if the call runs out of gas, the remaining sixty-fourth cannot finish the transaction.\n- **Holder rule.** The threshold is the maximum of one and the smaller of one whole token and a thousandth of supply, traced for 0, 6, 18, 24, 36 and over-36 decimals and for a supply under 1000.\n- **Artefacts.** The ABI file equals the compiled ABI, the manifest is schema-valid with empty constructor arguments, the deploy script rejects every chain but 4663 and reads no environment, and forge-std is vendored as ordinary tracked files.\n\n## Observations (non-blocking)\n- Anyone can re-dig a live token every ten days, so holders of a healthy token pay gas each cycle to object. The brief asks for exactly this.\n- A token can lie about balances or make its reads revert after being dug, which would stop its holders from saving it. The brief accepts token-supplied data and the README documents it.\n- Forced ETH through `SELFDESTRUCT` or block rewards is unrecoverable, which the static tools flag as locked ether. The brief forbids ETH and any withdraw path, and the README states it.","createdAt":"2026-10-07T05:46:42.990Z","verdict":null,"findings":[],"coverage":{"rows":[{"target":"MemecoinCemetery.dig(address,uint8)","verdict":"holds","why":"Permissionless by design;
