I found no defects I could back with a failing input, so .imd-findings.json holds {"findings":[]}. No repository file was changed. That means no defect turned up within what I could check; it isn't proof there are none.

What I read

• src/ProjectRegistry.sol (all of it), the only contract this launch deploys. I traced every function that changes state: applyListing, challenge, challengeForBeneficiary, onOracleResult, onOracleFailure, expire, claimBond, setBeneficiary, plus the constructor and projectOwner.
• src/oracle/OracleAttestation.sol, checked against the oracle-consumer reference (struct, type hash, domain, decoders).
• src/Stacker.sol, for context only; this launch doesn't deploy it.
• test/trial/TrialVenue.sol, skimmed, along with the mock requests() getters and the fork tests that call the real one.
• launch.json: it has only the allowed keys (kind, contracts, notes), seven string arguments in the constructor's order matching the brief, and notes of 2,031 characters.
• docs/panel-rules-v2.md: the version 3.1 trader and feeGuard text matches the strings in the contract exactly.

Checked against the brief, all holding

• Owner-only applications: NotProjectOwner fires before any fee. A project that reverts, gives a malformed answer or reports zero has no owner. The 30,000 gas cap can't be gamed by limiting the caller's gas, because the rest of applyListing needs far more gas than that trick would leave.
• Answers: only the Intake can deliver one, only for this contract's own open request, with each oracle request id used once. The signature must be for this contract, issued after the ask (300 s tolerance), from a panel of 15 with at least 11 agreeing, filed under chain 1.
• Settling: a "yes" lists the project or keeps it listed, with the bond going to the beneficiary and the cooldown not restarted. A "no" rejects or delists and returns the bond. A failure only clears the question and returns the bond.
• Clearing and bonds: expire works after a day or once the Intake has completed the request. A bond the token refuses is recorded in bondOwed and claimed with claimBond. The tokens the contract holds always equal open bonds plus bonds owed.
• Beneficiary handoff: setBeneficiary is blocked while a question is open and allowed once a day. A handoff then forces challengers to name the expected beneficiary, so a challenge can't be redirected to a different wallet.
• Question text: applicant text is limited to printable ASCII without quotes, backslashes or brackets, so the JSON body stays valid. Each rule is under 512 characters, which the tests check.
• Forbidden features: no owner, no minting, pausing, delegatecall, selfdestruct, proxy or initializer, and the constructor makes no external call.

Accepted by the brief, not reported

• Anyone can apply for a project with no owner, so they can tie up its one question slot for 0.5 IMD per try.
• A challenger can make a failed question come back, which returns their bond and loses only the fee.

What I couldn't reach

• No RPC URL is set on this machine. So I couldn't read the live Sepolia contracts (Intake v2, Stacker 0x0457…314d, TestIMD, TestSIMD, TrialVenue 0xf252…6fef, test run 5's registry), and the Intake v2 source isn't in the repository. I relied on the fork tests' and mocks' view of its requests() getter and its callback behaviour.
• The 12 fork tests and 2 mainnet-manifest checks were skipped.
• Tests: forge test --offline passed 232 tests with 0 failures and 14 skipped, out of 246.

Prepared the run 6 launch handoff: added an exact-manifest factory test, README updates, and ADAPTATION.md. Contracts, manifest, and build configuration remain unchanged.

Validation passed: forge build, 233 offline tests, and all 12 fork tests. Offline runs have 14 expected skips.

No transaction was broadcast. The confirmed registry address must be recorded after deployment.

Updated only launch.json, preserving the exact ProjectRegistry deployment arguments and clarifying the launch notes.

Validation passed: manifest structure, compiled constructor ABI, forge build, 233 offline tests, and all 12 fork tests. Two mainnet-manifest checks remain skipped as expected.

The review is complete and the findings file is written and validated.

Outcome: the permission model of the ProjectRegistry holds. No critical, high or medium defect was found in the Access Control, Trust Gap or Asymmetry areas. The file .imd-findings.json holds one low finding, two documented trust assumptions, and coverage rows for all nine entry points plus the manifest and one invariant.

What was checked

• Every state-changing entry point was traced for caller, guard, writes and failure paths. Only the Intake can settle or clear a question, and only for a request id the registry created. A stranger who pays the Intake and names this contract as callback reaches UnknownRequest. A signature for another consumer, an answer issued before the ask, a short panel, or a reused request id all revert before any effect.
• Paired surfaces were diffed: apply versus settle, challenge versus defend or delist, failure versus expire, bond payout versus claim. Writes mirror correctly and the defended bond goes to the beneficiary frozen while the question is open.
• The manifest has only the schema's keys, seven string arguments in declaration order matching the brief, and correct EIP-55 checksums. The live Sepolia Intake v2 answers requests(bytes32) and priceOf with the shapes the registry decodes.
• The offline suite passes with 233 tests and 14 skipped fork or mainnet checks.

Findings reported

• Low: a listed project's beneficiary can hold the single challenge slot by challenging itself, and a defended self-challenge pays the bond back to itself. Each round costs only the oracle fee, while any other challenger risks the full bond. An honest challenger whose reason would point the panel at the real violation keeps reverting with AskOpen. The author's regression test records slot buying as a retained limit, but not this cost asymmetry. Reproduced in test/scratch/SelfChallengeHog.t.sol.
• Info: the applicant gate fails open when a project's owner() cannot answer within the gas cap or returns a malformed word. This is the behaviour the brief specifies and is recorded as a trust assumption.
• Info: no signer rotation or Intake change is possible without a redeploy, by the no-owner design.

Not reached: nothing in the assigned area was left untraced. Fork tests were not run because no RPC environment variables are set on this machine; the live Intake reads above were done directly with a public Sepolia endpoint instead.

The review is complete and the findings file is written. No source files were changed (git status is clean apart from the untracked findings file, which the task asks for).

Outcome: no defect found in the assigned area. The control flow of the ProjectRegistry holds against the Execution Trace, Periphery and First Principles guides. The file records one info-level trust note and eleven coverage rows, all nine entry points marked holds.

What I verified

• Offline suite: 233 tests pass, 14 skipped (fork and mainnet-manifest tests).
• Live Sepolia fork: both Sepolia fork suites pass against the real Intake v2 and the test run 2 Stacker through a public RPC.
• Live Intake source (Sourcify): the requests getter returns exactly the tuple the registry declares, and complete marks the request completed before a one-shot callback. So expire and the deadline logic behave as intended.
• Live facts: callback gas 1,000,000, price 0.5 test IMD, Stacker tokens match launch #1129, venue owner matches, and run 5's registry has the same signer, Stacker, bond and chain settings.
• Body limits: every rule is under 512 characters (the trader rule is 505), and the longest application and challenge questions are 1,010 and 1,107 characters.
• Manifest: three schema keys, seven string arguments in constructor order equal to the brief, notes 2,031 characters. Since run 5 only the trader rule string and its comment changed.
• Callback gas: every cold settlement path stays under the mainnet 200k stipend.

Specific traces that came up clean

• The owner gate cannot be bypassed by starving the owner() staticcall of gas: after a forced out-of-gas, less than 1/64 of the gas remains, far short of the fee pull and Intake request.
• Answer replay, cross-question delivery, pre-ask answers and expired questions are all refused. Pairing of an answer to its request rests on the Intake writer, exactly as the oracle-consumer reference specifies.
• Bond accounting never blocks settlement and the registry's balance always covers owed and open bonds.

The one note recorded is a design-accepted trust assumption rather than a defect: with no owner, the oracle signer and action id are fixed for the registry's life, so a key rotation or action retirement by IdentityMD would stall every later question. The brief's no-owner design wins over the reference's advice, and the mainnet registry inherits the same dependency.

Added 13 tests covering deferred-bond accounting, claim recovery, and signer failure paths. Invariants exercise 256 random sequences of 96 calls.

Offline verification passed:

• forge build: successful
• forge test: 246 passed, 0 failed, 14 skipped—12 fork tests and 2 mainnet-manifest checks

All changes are under test/.

The findings file is valid, both snippets match the tree, and git shows no tracked-file changes (the findings file and test/scratch/ are untracked and allowed).

Result: no medium or higher defect in the math, boundary or numerical-gap area. The registry has no divisions, no scaling, and only checked additions on values bounded by immutables, so the precision guide had nothing to bite on. The boundary work turned up one low and one informational item, both in projectOwner.

Findings written to .imd-findings.json:

• Low, src/ProjectRegistry.sol:243. The fixed 30,000-gas budget for owner() fails permissively. An honest project whose ownership resolves through four cold forwarding hops ending in a beacon proxy answers owner() at 38,100 gas, but the registry reads it as ownerless. A stranger then files the application and holds the slot for up to a day per 0.5 IMD, which is exactly what the owner gate was added to stop. Three hops already sit at the cap. Reproduced in a scratch test with measured costs per depth. No funds are at risk.
• Info, src/ProjectRegistry.sol:247. Any 32-byte owner() answer with zero upper bits is taken as an address. A project returning uint256 7 or bool true gets owner 0x…07 or 0x…01, so nobody can ever apply for it. Restrictive rather than exploitable, so recorded for awareness only.

What I verified as holding, with evidence:

• Deadline edges are consistent to the second. At exactly asked-plus-one-day the answer is still accepted and expire needs completed; one second later the answer is TooLate and expire works. The issuedAt tolerance is inclusive at 300 seconds and rejects 301.
• The live Intake v2 source from Sourcify sets completed in the same transaction as the callback, and its requests getter returns the four-field tuple the registry decodes, so the early-expire path cannot be raced.
• Minimum cold callback stipend per path, bisected: 70,489 listing, 64,130 rejection, 99,386 defended, 80,373 delisted. Sepolia's live callbackGas reads 1,000,000, mainnet's 200,000 leaves a 2x margin.
• Every version 3.1 definition fits the 512-character cap at maximum inputs; the trader rule is 505.
• Live Sepolia reads match the brief: price 0.5 test IMD, trial venue owner 0x4b91…6821, manifest arguments in declaration order.

Coverage: all nine listed entry points have a row (eight hold, applyListing carries finding 1), plus two invariant rows. The full offline suite passes at 233 tests with 14 fork tests skipped. Nothing in my area was left unreached.

The review is complete and .imd-findings.json holds the result. The working tree is otherwise unchanged, and the scratch test I used for gas measurement was removed.

Outcome: no defect found in the assigned area. The ProjectRegistry's value flows, bond accounting, and oracle-settlement paths hold against the Economic Security, Invariant and Flow Gap checklists. The file records one informational note and twelve coverage rows.

What I verified

• Bond conservation: every close path (signed answer, failure, expire) pays or records exactly one bond, after state is closed, to the wallet pinned when the challenge opened. The fee leaves to the Intake in the same transaction, so the registry balance always covers open bonds plus bondOwed.
• Settlement gas: a scratch test measured the minimum gas for every callback outcome, including a zero-balance recipient and a token that refuses the transfer. All settle in roughly 70k to 102k, against the 200k mainnet stipend.
• Live Sepolia reads: the Intake's requests() fourth return is completed, true for two settled request ids from the history notes, so expire's early path matches the live contract. The live priceOf for the Sepolia test IMD returns 0.5e18, so asks will not revert with OracleUnavailable at launch.
• Manifest: keys, one contract, seven string arguments in constructor order matching the brief, notes under 4,000 characters.
• Offline suite: 233 passed, 2 skipped (the mainnet-manifest checks), none failed.

The one note (severity info): delisting ends a listing at the answer block, never at the block a breach began, and the cooldown blocks every challenge after listing. A project whose code can change after judgment keeps every point earned through the cooldown and until the challenge settles. The design notes state this tradeoff deliberately, so I recorded it for the judge rather than as a defect. The signed attestation's unused figure field, or the indexer, could carry a breach block if the author wants to close it.

Leads I rejected, so the judge need not re-trace them: beneficiary self-challenge holding the question slot (costs 0.5 IMD per round and gets a real verdict, no immunity gained); application spam on ownerless projects (documented known limit); a beneficiary naming the registry or a blocked wallet as its own payee (self-harm only).

Review complete. The findings file is written at .imd-findings.json and the tracked tree is unchanged.

Outcome: nothing blocks this launch. The seven specialist items reduced to five findings, two low and three informational. No critical or high finding, so no proof test was needed.

What I kept, after reproducing each against the code

• Low, owner gate fails open past the 30k gas cap (merged from audit_math and audit_permissions, same root cause). The specialist's claim that a 4-hop owner chain already trips it did not reproduce under this build. Measured cold, a beacon proxy behind an Ownable costs about 13.3k and each forwarding hop about 3k more, so projectOwner still answers correctly through 6 hops and only returns zero from 7. The bypass is real but exotic, and it is the brief's stated design, so low.
• Low, beneficiary self-challenge costs only the fee. Reproduced: the defended bond goes to the beneficiary, so a self-challenge costs 0.5 IMD per round while an outsider forfeits 5. The author already records this as a retained limit. I noted that the specialist's proposed fix, refusing the beneficiary as caller, does not close it since a second wallet gets the same result.
• Info, uint256 or bool owner() locks a project out. Reproduced; fail-closed, no funds or slot at risk.
• Info, signer, Intake and action fixed for life (merged from audit_permissions and audit_flow). Trust assumption of the no-owner design, not a defect.
• Info, delisting is not retroactive. Documented trade-off in the design notes.

My own pass found nothing further. Checks I ran beyond the specialists: runtime 23,295 and initcode 24,874 bytes, both within the limits; no forbidden opcodes; the manifest has schema keys only, seven arguments in declaration order, and notes of 2,196 characters; no workflow directory on the branch; the version 3.1 trader rule matches the docs character for character at 505 of 512; the longest question at maximum inputs is 1,107 of 2,000. I also traced a possible 63/64 gas trick against the owner gate and confirmed it cannot work, since the rest of applyListing needs far more than the 1/64 remainder. The full suite passes with 246 tests and 14 skipped fork or mainnet-manifest tests.

Coverage records all nine listed entry points plus three invariant rows. Two entry points carry findings (applyListing and challengeForBeneficiary), the rest hold.
