Source delivery only: do not deploy to a public blockchain, launch a traded token, create a liquidity pool or publish a website.\n\nScope:\n- A rental escrow contract, a mock token with 6 decimals, tests, local deployment/seed scripts and documentation.\n- The browser interface and persistent backend will be added in a later iteration. Provide contract events and integration documentation for them.\n\nRules:\n1. Each equipment item can have at most one active reservation or rental.\n2. Reserving an available item transfers the exact required deposit into escrow and creates the reservation atomically.\n3. Each reservation snapshots its policy version, deposit, cancellation fee and reservation expiry. Later policy changes affect only new reservations.\n4. Before expiry, the renter can cancel a reservation that has not been checked out. Credit the deposit minus its snapshotted cancellation fee.\n5. Before expiry, authorized staff can check out a reserved item, changing its state to rented.\n6. At or after expiry, anyone can expire a reservation that has not been checked out. Apply the same snapshotted cancellation fee. Rented items do not expire under this rule.\n7. Authorized staff can confirm return of a rented item. Credit its full deposit and make the item available again.\n8. Refunds are withdrawn by their beneficiary. Each deposit can be refunded or credited only once.\n9. An administrator can manage items, staff and policies. Revoked staff immediately lose permission. Administrators can withdraw earned cancellation fees, but cannot withdraw escrowed deposits or outstanding refund credits.\n10. Repeated requests and transaction retries must never create duplicate deposits, reservations or refunds. Document how callers identify and recover an uncertain transaction outcome.\n\nValidation:\nInclude unit, fuzz and invariant tests covering competing reservations, duplicate actions, unauthorized callers, staff revocation, exact expiry boundaries, policy changes during existing reservations, refund retries and accounting conservation. Escrow obligations plus refund credits and earned fees must never exceed the contract's token balance.\n\nDelivery:\nProvide exact setup, build, test and local-demo commands, dependency versions, example interactions, event definitions, trust assumptions and known limitations. Include test results actually obtained and identify any checks that could not run. Staff confirmation is the trusted signal for physical checkout and return.\n\nToken name: kkk\nToken symbol: dds\nTotal supply: 1000000","parentJobId":null,"planHash":"94624c36d7a60dadd7034620a3292d9695cafb9bf593578ec630d709b5aa13ef","previousHash":"0000000000000000000000000000000000000000000000000000000000000000","projectId":"0b32e9c2-5e73-434d-b219-5c39c759f59c","publication":{"commit":null,"deliveredAt":null,"repoUrl":"https://github.com/identity-md-launches/launch-1988-kkk"},"receiptIdentity":{"adapter":"0xde152afb7db5373f34876e1499fbd893a82dd336","chainId":1,"collection":"0x0000ec93127baa929e58e97dd0095a2bfb38ec1d","registry":"0x8004a169fb4a3325136eb29fa0ceb6d2e539a432"},"registry":"0xb6d0a187b050fa5bb0b87033a203f37becf4a775","research":[],"schema":"identitymd-work-v1","signals":[{"agentId":"51315","feedbackHash":"e5c9080fee85b4636bd9dade979dc09995825968189d0cc8b795eccc494cebe7","nodeKey":"build_contract_project","submissionHash":"cb320b73b86ccfb0f5f688ef2e6a9b9ad635774b6bdd4a89533bc6e9868351ad","tag1":"verification:checks","tag2":"acceptance-v2","value":1}],"site":null,"snapshotHash":"4a1b0521d059fdbb588a02855f9ad8a3b9b01e212f3a52de3a0ddbf29ee9f386","state":"completed","submissions":[{"artifacts":[],"attempt":1,"bundleHash":"3c615fc7d7296c3b35bdd00f1c95647e3e13bc52bb8d12f9a669c44cc3bf9338","device":"e3a598aae0640402","findings":[],"hash":"cb320b73b86ccfb0f5f688ef2e6a9b9ad635774b6bdd4a89533bc6e9868351ad","nodeId":"71a2ad1d-a35e-467d-af01-edfb87b90156","outcome":"completed","summary":"The clean clone builds, formats and tests green with no stray `.gitmodules`. The work is complete and committed.\n\n## Delivered\n\nA standalone Foundry project at the repository root, committed as `b92a557`.\n\n- **Contracts** in `src/`. `RentalEscrow` is the deposit escrow. `MockPaymentToken` is the kkk / dds token with 6 decimals and a fixed 1,000,000 supply minted to a constructor-supplied holder.\n- **Tests** in `test/`. 47 unit tests, 9 fuzz tests, 8 stateful invariants driven by a handler, plus token and script tests. All 64 pass under the verifier's fuzz seed.\n- **Scripts** in `script/`. An env-driven deploy and seed script whose logic the tests call directly, and `demo.sh`, which walks the full flow on Anvil with cast.\n- **Docs**. `README.md` covers setup, commands, deployment parameters, operational duties, trust assumptions and limitations. `docs/INTEGRATION.md` gives the events, ABI surface and the uncertain-outcome recovery procedure for the UI and backend. `docs/TEST-RESULTS.md` records the results obtained here.\n- **Dependencies** vendored as plain files: forge-std v1.9.7 and OpenZeppelin v5.1.0. The compiler is pinned to 0.8.26, ffi and filesystem access are off.\n\n## Design points worth knowing\n\n- **Idempotency** is a caller-chosen `clientRef` on reserve, unique per renter. A replay reverts with an error that carries the existing reservation id, and the backend can resolve any unknown outcome with one view call.\n- **Policy snapshots** store deposit, fee, policy id and expiry on each reservation. Callers pass the policy id they quoted, so an admin change between quote and inclusion reverts instead of silently charging a different deposit.\n- **Accounting**. Escrowed deposits plus refund credits plus accrued fees are tracked separately and the admin can only withdraw from accrued fees. The invariant suite asserts the balance equals these liabilities and that ghost totals of deposits in equal payouts plus liabilities.\n- **Exact boundary**. At the expiry timestamp cancel and checkout revert and expire succeeds. Rented items never expire.\n\n## Verification performed\n\n- `forge build`, `forge test` with the verifier's seed, and `forge fmt --check` all pass, both in the working tree and in a fresh clone.\n- The Anvil demo ran end to end, with retries, competing reservations, over-withdrawals and double refunds all rejected as expected.\n- Five bugs injected one at a time into the escrow were each caught by the suites. I also found that handler assertions were silently swallowed under the default invariant config, so `fail_on_revert` is pinned to true and the handler catches every legitimate revert itself.\n\n## Not run\n\nSlither and Mythril are not installed here, and no long fuzz campaign or public deployment was done. Both are noted in the README and results document. One environment note: the sandbox pins any `.gitmodules` path read-only, so OpenZeppelin's own copy could not be deleted from disk. It is excluded via `.gitignore` and is absent from the commit.","treeHash":"cda991c0f20b5accef40e66ff3dbe0c7efb40dc8","usage":{"cachedInputTokens":3103460,"inputTokens":994,"model":"claude-fable-5-1","outputTokens":96666,"runtime":"claude","turns":61,"wallClockMs":1330461}}],"verification":[{"checks":[{"durationMs":2579,"exitCode":0,"name":"build","output":"Compiling 44 files with Solc 0.8.26\nSolc 0.8.26 finished in 2.50s\nCompiler run successful!\n","passed":true},{"durationMs":1078,"exitCode":0,"name":"test","output":"No files changed, compilation skipped\n\nRan 47 tests for test/RentalEscrow.t.sol:RentalEscrowTest\n[PASS] test_adminHandover_cancelPending() (gas: 110567)\n[PASS] test_adminHandover_twoStep() (gas: 210391)\n[PASS] test_cancel_afterCheckoutReverts() (gas: 399841)\n[PASS] test_cancel_boundary_lastSecondOkExactExpiryRejected() (gas: 629474)\n[PASS] test_cancel_creditsDepositMinusFee() (gas: 605011)\n[PASS] test_cancel_onlyRenter() (gas: 416128)\n[PASS] test_cancel_twiceReverts() (gas: 478608)\n[PASS] test_cancel_unknownReservation() (gas: 34754)\n[PASS] test_cancel_withFullFeePolicyCreditsNothing() (gas: 598962)\n[PASS] test_cancel_withZeroFeePolicyCreditsEverything() (gas: 538805)\n[PASS] test_checkOut_afterCancelReverts() (gas: 474284)\n[PASS] test_checkOut_boundary_rejectedAtExpiry() (gas: 447453)\n[PASS] test_checkOut_byStaff() (gas: 442529)\n[PASS] test_checkOut_twiceReverts() (gas: 397927)\n[PASS] test_checkOut_unauthorizedCallers() (gas: 409542)\n[PASS] test_confirmReturn_creditsFullDeposit() (gas: 585849)\n[PASS] test_confirmReturn_requiresRentedStatus() (gas: 358342)\n[PASS] test_confirmReturn_twiceReverts_singleCredit() (gas: 507288)\n[PASS] test_confirmReturn_unauthorized() (gas: 423868)\n[PASS] test_constructor_revertsOnZeroAddresses() (gas: 6107)\n[PASS] test_constructor_setsTokenAndAdmin() (gas: 33577)\n[PASS] test_createPolicy_validation() (gas: 333131)\n[PASS] test_delistingDuringReservation_doesNotBreakLifecycle() (gas: 549008)\n[PASS] test_expire_byAnyoneAtExpiry() (gas: 904161)\n[PASS] test_expire_cancelledOrUnknownReverts() (gas: 494990)\n[PASS] test_expire_longAfterExpiryStillWorksOnce() (gas: 475808)\n[PASS] test_expire_rentedItemsNeverExpire() (gas: 401399)\n[PASS] test_fullLifecycle_itemReusedAcrossManyRentals() (gas: 2312586)\n[PASS] test_items_adminManagement() (gas: 370704)\n[PASS] test_policyChange_doesNotAffectExistingReservation() (gas: 984626)\n[PASS] test_reserve_competing_secondRenterRejected() (gas: 402468)\n[PASS] test_reserve_feeOnTransferTokenIsRejected() (gas: 906172)\n[PASS] test_reserve_happyPath() (gas: 466093)\n[PASS] test_reserve_insufficientAllowanceOrBalanceTakesNothing() (gas: 735916)\n[PASS] test_reserve_rejectsStalePolicyQuote() (gas: 183753)\n[PASS] test_reserve_rejectsUnknownOrDelistedItem() (gas: 127498)\n[PASS] test_reserve_rejectsZeroRef() (gas: 41904)\n[PASS] test_reserve_retryWithSameRefRevertsAndNamesReservation() (gas: 821950)\n[PASS] test_reserve_sameRefDifferentRentersAreIndependent() (gas: 705778)\n[PASS] test_setStaff_onlyAdmin() (gas: 121884)\n[PASS] test_staffRevocation_isImmediate() (gas: 689324)\n[PASS] test_views_revertOnUnknownReservation() (gas: 25884)\n[PASS] test_withdrawFees_adminOnlyAndBounded() (gas: 833418)\n[PASS] test_withdrawFees_cannotReachEscrowedDeposits() (gas: 375914)\n[PASS] test_withdrawRefund_accumulatesAcrossReservations() (gas: 899609)\n[PASS] test_withdrawRefund_isPerBeneficiary() (gas: 508801)\n[PASS] test_withdrawRefund_paysOnceOnly() (gas: 623822)\nSuite result: ok. 47 passed;
