Implemented SqueekRaider and RaiderCard, with vendored dependencies, ABI exports, and deployment/API documentation.

Verified:

• forge build and forge fmt --check
• 44 offline tests with the required fuzz seed
• 2 Sepolia fork tests
• Runtime and initcode size limits

Independent review, manifest generation, and deployment remain separate stages.

Created launch.json with SqueekRaider’s three approved constructor addresses. RaiderCard is created internally. Local manifest and ABI checks passed; only launch.json changed.

forge build and forge test both stopped with Read-only file system (os error 30), so build and test verification remains incomplete.

The permissions review found one defect: a low-severity asymmetry. All nine entry points have a coverage row, and the results are in .imd-findings.json. I changed no source files, and I deleted the scratch test after running it.

Finding 1 (low): a KO can wipe out a paid upgrade with no refund (src/SqueekRaider.sol:518)

• upgrade() takes 10·2^L Scrap straight away, then queues the change under the stance's current KO epoch.
• If that stance is KO'd before round E, the queued upgrade is silently cancelled (_preview, lines 665–672 and 676–683). The Scrap is not returned and the level does not change.
• revive(), the other paid action, is queued in a way the KO check never cancels, so a paid revive always lands.
• Reproduction (local Foundry test with the project's mocks):
  1. Enlist Squeek 1 as a Striker.
  2. Run 11 Wheel rounds; the last round's data hash is chosen so the boss's move is FRENZY. Then run an 18-round nap.
  3. At live round 31, call upgrade(1), which queues it for round 32.
  4. FRENZY lands at round 31 and KOs the Strikers.
  5. After round 32 the raider has 1 Scrap (it had 11 before the upgrade), is still level 0 and is KO'd.
• The brief says the upgrade is "paid now" and "a KO wins", but it doesn't say what happens to the Scrap, so this is your call. Either refund the Scrap on cancel, or document the risk in the contract comments and on the How It Works page.

What holds:

• Controller checks: enlist, setStance, upgrade and revive all check the controller per id. That is the owner, or the staking depositor when staked. A failed read resolves to address(0), so every one of those actions fails safe.
• Open-to-anyone functions: advance, poke, rest and bury are open, as the brief says. None of them lets a third party do more than help the raider's owner.
• Demo raiders: enlistDemo derives the demo id from the caller's own wallet, so nobody can claim another wallet's demo raider.
• No roles: the constructor grants no role and makes no outside reads, and the deploying factory gets no privilege.
• ABI exports: both files in docs/abi match the compiled ABIs.

Live Sepolia checks:

• I tried to fake a burn so that bury would work on a live Squeek. It isn't feasible: the NFT reverts only for missing tokens, and its ownerOf costs about 18k gas, well under the 500k the contract forwards. Starving the call of gas would leave too little to finish bury.
• The staking contract is an upgradeable proxy, so whoever controls that proxy is an outside trust assumption.
• The core's state() work total matched the starting work total of a roundPage() call. I checked only one sample, a stretch with no active rounds.

Tests and limits: the 44 existing tests pass. I did not run the Sepolia fork test suite. There is no launch.json yet, so no manifest was reviewed.

I found one low-severity defect and no high or critical issues in the economics of src/SqueekRaider.sol. The results and coverage rows are in .imd-findings.json; no repository files were changed.

Finding 1 (low): a run with zero work doesn't update lastRunWork (src/SqueekRaider.sol:323, if (runWork != 0) lastRunWork = runWork;) The brief says each nap start stores the work of the run that just ended, and the next boss's HP is sized from it. The README also counts an active round as a Wheel round even when its work is zero. When every Wheel round in a run has zero work, the code keeps the previous run's value instead of storing 0. So after a 12,000-work run, the next boss gets up to 12 times the HP the brief prescribes (sized from 12,000 instead of the 1,000 minimum).

• Reproduction: wheel round 1 with work 12,000, idle to round 3, then wheel round 4 with work 0, idle to round 6. lastRunWork is still 12,000 instead of 0. The attached Foundry test fails with 12000 != 0.
• Suggested fix: track whether any Wheel round happened since the last nap, and store the run's work (including 0) when it did. Only the case with no Wheel round yet keeps the 1600 default.

What holds:

• Damage credit conservation: the total credited to raiders equals the damage dealt, up to rounding. Boss overkill stays on the slain boss.
• Per-stance power: each stance's live power always matched the sum of its live raiders.
• Changes around knockouts: a knockout before a change takes effect cancels it. A change at the move's own round applies before the move lands.
• Pending actions: setStance replacement and cooldown, upgrades cancelled by a knockout, revive/rest during a boss kill, and burial after a knockout all behave as the brief says.
• Bounded checkpoints and trophies: checkpoints stop at eight bosses and trophies are awarded lazily, both as specified.
• Boss HP: HP rescales when party weight changes. Free demo raiders can't make a boss easier, because HP and damage both scale with the same party weight.
• Scrap and Dreams: they come only from the reward indices and are spent only on upgrade and revive. Nothing in the contract carries value.

How I checked: the existing suite passes (44 tests, 1 fork test skipped). Its fuzz test never covers settlement lag, burial, Dreamers or replacing a pending change. So I wrote a temporary fuzz test with all of those and ran it 500 times: credit conservation and per-stance power held every time. The first failure it reported came from my own test letting the clock run backwards, which can't happen on chain. With that fixed it passed. I deleted the temporary tests afterwards.

Slither leads: none of the listed lines is a finding. The random move is meant to be predictable (the README says so and the site shows it). The strict-equality and timestamp lines are intended round and epoch logic, and the unused return in bury is the intended "is it burned" check.

Not covered: the card renderer (RaiderCard, Text), the website, and the real Sepolia contracts, since the fork tests weren't run. All nine entry points have a coverage row: advance points to the finding and the other eight are marked "holds".

Added 38 tests covering failure paths, fuzz properties, and 24,576 invariant calls.

forge build and seeded offline tests pass: 82 passed, 0 failed, 1 skipped.

Reported one low-severity zero-work run defect with a failing proof in .imd-findings.json.

Sepolia verification remains unconfirmed: the RPC returned “historical state is not available.”

I audited SqueekRaider for control flow and found three defects: one medium and two low, none critical or high. All three are in .imd-findings.json with reproductions, and their snippets match the source lines. No tracked files changed; my scratch tests are deleted.

Finding 1 proof: it includes a self-contained Foundry test that fails on the current code. It passes in a temporary copy with a gasleft() floor added to both loops. That fix leaves only 88 bytes of runtime margin, down from 160.

Coverage:

• Entry points: all nine have rows and are marked finding with ref 1, because each runs advance or _advance(64). Apart from that, the guards I traced in each one held, and each row says so. launch.json isn't in the tree, so it's marked unreached.
• Three guides: I made all three passes myself, with no helpers:
  • Execution Trace: paging, queued changes taking effect at round E, and KO timing.
  • Periphery: CoreReader, Text and RaiderCard.
  • First Principles: anchoring, boundary cases, and state that must stay in sync.
• Checks that passed:
  • A 200-run scratch fuzz covered settlement lag, KOs, burns, boss kills and demo raiders. advance never reverted, the alive totals stayed in sync, previews matched saved state, and damage credits matched total damage apart from rounding.
  • A fork replay of the live core from round 0 to 1221 ran without stalling, and each page read cost about 146k gas against the 500k cap.
  • The existing offline suite passed all 44 tests; I did not run the repo's own Sepolia fork tests.
• Slither leads: I reviewed the medium-or-higher leads and found no defects behind them:
  • weak-prng is the formula the brief specifies; the zero-hash input is finding 2.
  • divide-before-multiply is just the base64 length calculation.
  • unused-return in bury is safe, because forcing a false "burned" read by limiting gas leaves too little to finish the call.
• Not covered: a low-gas false "burned" read in bury was reasoned through but not run as a test, because it can't complete. I also did not separately check the exact Scrap and Dream balances per raider beyond the existing tests.

The math audit found two low-severity defects and nothing critical, high or medium. The accounting core matched an independent reference model exactly. Findings and coverage are in .imd-findings.json, the source tree is unchanged, and my scratch tests are deleted.

Findings

Both have a Foundry proof that fails on the current code and passes with a candidate fix. I tried the fixes in a temporary copy, where the existing test suite still passed (44 passed, 1 skipped).

Finding 1 hasn't happened on the live chain: all 206 active records on the Sepolia core through round 1222 have work of at least 3.

What I checked

• Math Precision: I walked the HP formula, W flooring, rescaling, the damage units, Scrap and Dream indices, score flooring, narrowing casts, subtractions and overflow. Text.base64 and Text.decimal are also correct, and all art rows are 16 wide.
• Numerical Gap: a throwaway fuzz compared the contract against the reference model over 1,500 clean runs, covering settlement lag, KOs, burials, replaced changes, demos, Dreamers and zero-work rounds. Separate reachability checks confirmed it hit KO-cancelled changes, burials, blocked moves and repeated KOs.
• Boundary: I traced CoreReader decoding and caps, the reads in bury and the controller check, the anchor, and the time and round edges.
• Live data: real history replayed through the contract on a Sepolia fork up to round 1222, ending at the core's settled round and cumulative work. A 16-record page read estimates about 145k gas against the 500k read cap.

Leads I didn't report

• Gas cap: worst-case advance(64) measured about 37.6M gas and advance(128) about 77M, using 64 and 128 rounds that each had both a queued change and a wheel record. I suspected a 16.7M per-transaction cap would block these, but 30M-gas transactions are landing on Sepolia, so I dropped it.
• Site reads: the website's advance(128) read could still fail on an RPC provider with a low eth_call gas limit, but only after a very long backlog of that kind. I didn't test provider limits, so check this when the site is built.
• Forced burial by gas: this isn't feasible, because the gas left after a failed ownerOf read can't finish bury.

Coverage and limits

All 9 listed entry points have a coverage row: advance is marked finding, the other 8 holds, and none unreached. I added five extra rows: the cardURI view, three invariants and the CoreReader boundary.

• Mocks: the fuzz used mock contracts; only the replay and page-read checks used the real core.
• Other reviewers' areas: I covered permissions, economics and control flow only where they touch the math.
• Manifest: there is no launch.json in the tree yet, so I didn't review one.

Review complete. The findings are in .imd-findings.json at the repository root, and the tree is otherwise unchanged (the findings file is gitignored, so git status is clean).

Outcome: all eight specialist findings reproduce; they collapse into five distinct defects, none above medium. The code holds no loss-of-funds or permission defects: there are no funds, no owner, and every privileged path I traced is guarded as the brief requires.

Findings kept, after merging and recalibration:

1. Medium. Queued rounds cost about 312k gas per budget step, so after a settlement stall with 53 or more queued rounds, advance(64) and every write exceed the 2^24 per-transaction cap that Sepolia enforces. The flow specialist's proof fails on this code with the stated reason and is attached. Recovery is manual and permissionless, so medium rather than high.
2. Low. A zero-work Wheel run does not update lastRunWork, so the next boss is sized from an older run. Three specialists reported this; merged into one, with the shortest proof attached.
3. Low. The first nap after anchoring takes its move from a zero hash, so it is always FRENZY. Reproduced with my own test.
4. Low. A raider with a pending enlist renders with the Dreamer item. Two specialists reported it; merged. Reproduced with my own test.
5. Low. A KO before round E cancels a paid upgrade with no Scrap refund. The README documents this, so the author may keep it, but it should then appear in the HOW IT WORKS text.

My own pass over the entry points, the accounting seams (epoch snapshots, boundary splits, trophy and cancel paths), CoreReader validation and the manifest found nothing further. The project's own suite passes (82 tests). The coverage record answers all nine entry points plus the credit invariant and the manifest. Slither's equality, timestamp and weak-PRNG lines are the intended round arithmetic and formula and were dropped.

Sources:

• Ethereum Foundation: Fusaka gas cap update
• The Defiant: gas limit cap for Fusaka

I fixed four of the five findings and disputed the fifth, keeping its behaviour and documenting it. The reviewer's proof now passes, with and without --isolate. Answers for all five are in .imd-responses.json, which git ignores through .git/info/exclude, presumably so the harness can collect it separately. I didn't commit anything, since the brief didn't ask me to; the changes are in the working tree.

• Spend limit beyond the suggested fix: the reviewer suggested only the gas floor. I added the spend limit so the stopping point doesn't depend on a caller's higher gas limit, and so a 64-ID enlist still fits under the cap during a backlog.
• Reviewer's expected value: for the first-nap finding, the reviewer expected pendingMove() to return (1, 2, false). It returns (0, 2, false) with no move in effect, because roundPage only pages forward and the last Wheel before anchoring can't be found in bounded work.
• Low-gas calls: a call with under 2,000,000 gas may process no rounds, but its action still goes through. That can't change a past round, because every action takes effect at a future round.
• Site work for later: the site needs to show no move while armed is false before the first Wheel, because move and cover() report unset defaults then. docs/API.md says so.

Check results

• Build and format: forge build and forge fmt --check pass.
• Tests: forge test with the required seed shows 53 passed, 0 failed and 1 skipped. That count includes the proof copy in test/scratch/, so 52 are delivered tests, 8 of them new. The skip is the network-only fork suite in the offline run.
• Fork suite: 2 of 2 pass at block 12059021 through the Tenderly RPC. PublicNode no longer serves that block and dRPC didn't respond, so I changed the README's fork command to use Tenderly.
• ABIs: the exports are unchanged.
• Not run: Slither and Mythril. The source adds no constructs from the rejected detector list.

Runtime size

SqueekRaider runtime is now 24,542 bytes, only 34 bytes under the 24,576 limit. The first version of these fixes went over the limit. I got back under by moving repeated expressions into small helpers (_applies, _blocked, _seasonOf), with no behaviour change. Any further source change needs a new size check.

The manifest is done and verified. Only launch.json changed.

What I found. The accepted source changed since my last manifest round, but only inside SqueekRaider's runtime logic: a gas floor for advance, a guard against arming a move before the first processed Wheel, and small refactors. The constructor signature is still core, nft, staking, all addresses, so the contract list and arguments in the manifest remain correct and match the brief's three Squeekchain addresses and the deployment test.

What I changed. The notes now describe the constructor as it is in the accepted tree: it stores the three immutables, creates the RaiderCard renderer, and summons boss 1 from the default lastRunWork without any external call or chain read. That tells the reviewer why it deploys on the empty rehearsal chain. The contracts section is byte-for-byte what was accepted before.

Verification.

• The manifest has exactly the keys kind, contracts and notes, one contract with three string arguments, and notes well under the limit.
• No owner argument exists, which matches the brief's "no owner, admin, pause, upgrade" requirement, and the deployment test confirms no owner() exists on the game.
• Build succeeds. SqueekRaider runtime is 24,542 bytes, under the EIP-170 cap, and initcode is 33,907 bytes, under the factory's cap.
• The full suite with the verifier's fuzz seed passed: 52 tests passed, 0 failed, 1 skipped. The skipped test is the Sepolia fork integration test, which skips by design without a fork URL.

Git status shows launch.json as the only modified file. Nothing else was touched, and no network dependencies were added.

The revised suite passes: forge build succeeds, and the seeded forge test gives 94 passed, 0 failed, with only the optional Sepolia fork suite skipped. The invariant ran 256 sequences of 96 calls with no reverts.

What changed in this revision

• Invariant oracle (test/invariant/RaiderHandler.sol, test/RaiderInvariant.t.sol): my invariant failed on the revised code because the oracle didn't know the new rule that a nap before the first processed Wheel has no move. The oracle now follows that rule. It also stores each finished run's total work, zero included, which the revision fixed after my earlier finding. After every call the invariant now also checks lastRunWork and pendingMove() (nap length and whether the move is armed).
• New test/GasPartition.t.sol, testing the new gas-limited advance:
  • Processing a backlog of active, idle and queued rounds with random per-call gas limits, called directly or through actions, gives exactly the same result as processing one round at a time.
  • Every early stop resumes correctly.
  • A call with too little gas changes nothing and doesn't revert.
  • A single-ID action succeeds at every gas limit tested, and the round it takes effect in doesn't depend on how far processing got.
• test/README.md: removed the old zero-work defect note (now fixed) and described the new tests and finding.

Findings, in .imd-findings.json

• Low, with a runnable proof: before each action, the round processing stops only when 2M gas is left (GAS_RESERVE), and that is all the action gets. A 64-ID enlist needs about 4M gas when no rounds are waiting. With 64 queued rounds waiting, it runs out of gas at every limit from 4M to 13.5M and only succeeds from 14M. So a gas estimate made while nothing is waiting turns into a failed transaction once the core settles a batch. Nothing is lost when this happens. The proof has two tests: the control (8M gas, no backlog) passes, and the backlog case fails. The suite does not treat this behaviour as correct. Single-ID actions are not affected.
• Info: the brief says every nap gets a move, but the revision gives no move to a nap before the first processed Wheel. This is documented in the README. It's listed so the reviewer can confirm the requester accepts it.

The proof file was written in test/scratch/, which isn't submitted; its full source is embedded in the findings file. I haven't committed anything.

The review is settled and written to .imd-findings.json. No source file was changed.

Earlier findings, settled against the revised code

• Gas cap after a backlog (medium): fixed. The gas floor in _advance and _page stops steps at 10M spent or 2M left. My attached proof and the flow specialist's proof both pass now, with and without the backlog of 64 queued rounds. Runtime is 24,542 bytes, 34 bytes under the limit.
• Zero-work run not stored (low): fixed. A wheelSeen flag now stores run work including zero at nap start. All three proofs pass.
• First nap uses a zero hash (low): fixed by the first option I offered: no move is armed until a Wheel has been processed. Traced and confirmed. Kept as an info row so the requester signs off on the deviation from "each nap: move".
• Pending raider draws the Dreamer item (low): fixed. The renderer returns no item for a stance above 3. Proof passes.
• Upgrade Scrap lost on a KO cancel (low): dropped as a defect. The author's reading of the brief is right and the rule is now in the NatSpec and README. Kept as an info row for the site stage.

One new low finding, from the independent tester and reproduced with a proof that fails on this code. During a backlog the inner advance leaves a batch action only the larger of 2M or the limit minus 10M. A 64-ID enlist needs about 3.8M alone and succeeds at 8M with nothing behind, but with 64 queued rounds it reverts at every limit from 1M to 13.5M and first succeeds at 14M. Single-ID actions are unaffected. The suggested fix is to size the reserve by the batch.

Other checks: the full suite passes (94 tests), the manifest's three constructor addresses match the brief in order, and the slither and aderyn lines are either the intended formula or non-reproducing style notes. Coverage answers all nine entry points: enlist, setStance, rest and poke point at the new finding, the rest hold.

Implemented the frontend, static export and validation evidence.

Build/typecheck passed, along with 48 browser tests and final layout/accessibility rechecks. Export: 1.52 MB; total additions: 2.59 MB.

Results are in docs/FRONTEND-VALIDATION.md. Design documentation is in docs/DESIGN.md because root-file creation is prohibited.

No live transactions or publishing performed.

Recorded four reproducible findings in .imd-findings.json. Implementation and export remain unchanged.

• High — bug: Two card renders exhaust the snapshot’s 16,000,000-gas budget, blocking real-Squeek play. At Sepolia block 12060007, Squeek #1 plus its wallet’s demo failed; the identical snapshot succeeded with card rendering omitted.
• Medium — bug: Refresh does not retry failed wallet inventory requests.
• Medium — bug: Read timeouts incorrectly tell visitors to check a transaction hash.
• Medium — bug: Pending transaction feedback disappears on How it works and Leaderboards.

Build/typecheck passed in a temporary copy. All 16 asset hashes, deployment fields, pinned ABI bytes and canonical ABI hash verified. Configured RPC returned chain 11155111 and 24,542 bytes of game code. Recovery findings were reproduced through source/DOM interactions. Fresh Chromium/WebKit checks could not complete because browser startup failed; supplied browser evidence is distinguished below.

The visual idea is a cooperative hamster raid presented as a dark board, carried by pixel animals and a prominent health bar.

The five missing requirement groups below share the single gas-budget defect. “Met, inherited” identifies accepted contract-stage evidence, not a new security audit.

I couldn't finish this revision. The shell failed on every attempt (about 8 tries) with Sandbox is required but failed to initialize: Failed to create bridge sockets after 5 attempts. Restart to retry. Running outside the sandbox is turned off. The browser tool failed too: Chromium distribution 'chrome' is not found at /opt/google/chrome/chrome.

So I couldn't install dependencies, typecheck, build, run tests, run the design probe, rebuild dist/ or regenerate dist/imd-deployment.json. I also couldn't run the reviewer's out-of-gas call against the RPC. Nothing I changed has been compiled or run.

What's in the working tree (not built, not tested):

• Card renders block play (high): readSnapshot in web/src/chain.ts no longer includes any cardURI reads. A new readCard loads one card per call with its own 16M gas limit, first after the advance(128) preview and, if that doesn't fit, from saved state. RaiderCard in web/src/App.tsx loads its card in a separate cached query. A failed card shows the placeholder hamster and doesn't affect game state or actions.
• Refresh doesn't retry inventory: refresh() now also refetches the wallet inventory when a wallet is connected, and the rest-all list on My Squeeks.
• Read timeouts mention a transaction: in web/src/errors.ts, only receipt-wait errors still mention a transaction hash. Other timeouts, including the TimeoutError raised when the fetch timeout expires, now say "The request timed out. Refresh to retry."
• Pending status disappears: Raid and My Squeeks keep their status panel beside their controls. Every other route now shows the shared status panel below its content, with the explorer link and Check receipt. This is slightly different from the reviewer's suggestion of one shared panel, so the status stays near the buttons on those two pages.
• Tests: web/tests/fixtures.ts now fails any batch with two card renders, as the real renderer does, plus a cardFail option, per-batch call records and an inventory request counter. web/tests/interactions.spec.ts has five new tests, one or more per finding.

What's out of date as a result: dist/ and its manifest still hold the previous build, so the exported site still has all four bugs and no longer matches the source. I also haven't written .imd-responses.json or updated the validation docs, since a "fixed" verdict would be untrue without a rebuild and a test run. If this tree is submitted as it is, it shouldn't be accepted.

To finish once the shell works: run npm ci --prefix web, then npm run build --prefix web (which typechecks, builds and regenerates the manifest), npm run check:export --prefix web and npm test --prefix web. Then run the reviewer's two-ID and six-ID reads against the RPC, update docs/FRONTEND-VALIDATION.md, and write the four responses.

.imd-findings.json records one high finding: bug: the committed static export omits all four review fixes.

All four corrections work in the revised source. However, dist/index.html still loads the previous bundle, so visitors receive the original failures.

The required change is to run the existing build, commit the resulting dist/ and regenerated manifest, and validate those exact files. Website files were left unchanged.

The frontend requirement ledger, grouped by brief clause:

The previous high finding is fixed. The committed export loads index-DDK-psNm.js and contains all four corrections. .imd-findings.json contains {"findings":[]}. Application files remain unchanged.

Both browser suites pass: 60 checks total, using committed export bytes and mocked wallet transactions. Runtime accommodations stayed outside the repository.

An isolated build reproduced the committed export byte for byte. Typecheck, canonical ABI verification, pinned ABI comparison, deployment binding, and all 16 asset hashes passed. Read-only Sepolia checks confirmed chain ID, deployed code, immutable dependencies, and successful state reads.

At 390×844, Play free occupies y=694–739. The live-data screen shows the owl, HP bar, wallet, and action without horizontal overflow. The probe found no overlap, clipping, contrast, or target-spacing failures. Its sole flag is uppercase “TEST NETWORK”, expressly required by the brief.

The frontend requirement inventory is below; deployed-contract implementation and security auditing remain prior-stage context.
