Audit Briefs, BriefsJury, BriefsText, ImdGatewayRequester and ImdOracle, live on Robinhood Chain. Briefs holds every IMD (seed pots, escrowed entry fees, creator earnings, the platform share): first look for any way to take, lock or misroute funds, or to break the exact solvency invariant (balance == open pots + creator owed + platform owed + queued fees + the fee of the brief being heard less the jury's price), or to stall a case so it can never settle.

Then the oracle path: an answer must land only for its own hearing (questionHash rebuilt on chain, delivery by IMD's Intake through BriefsJury.onImdAnswer, answer window, panel, EIP-712 signature for the jury's domain).

Then griefing by the current leader (mistrial timing, skipStalled and the stall clock, queue spam), admin powers and their bounds, gas (hearingGas and the 64/63 rule), and the text rules in BriefsText.check (the question must stay valid JSON and under 2,000 characters). docs/audit-internal-2026-10.md lists what our own reviews found and fixed; test/audit holds the PoCs

1.mediumPush payments on the live IMD token (which has an owner block list): one blocked address locks a whole case and its potsrc/Briefs.sol:676

        imd.safeTransfer(winner, prize);

docs/audit-internal-2026-10.md accepts push payments on the premise that "Standard bridged IMD can't" blacklist. That premise does not hold for the token Briefs is deployed on. The live IMD token on Robinhood Chain (0x5F7Bb59365ce557C26dbcAa4EE9d39A4b95B7127) is a LayerZero OFT ("BridgedFP") with a public blocked(address) view, a transfersEnabled() switch and an owner (0x047F606fD5b2BaA5f5C6c4aB8958E45CB6B054B7, the same address that owns IMD's Intake).

On a fork of the live chain, setting blocked[x] (mapping at storage slot 13) makes transfer(x, 1) from the live Briefs revert with "BridgedFP: blocked", and clearing it makes the same transfer succeed.

Briefs pays by push inside the functions that advance the docket: the pot in _maybeSettle (line 676, reached from fulfill, mistrial, skipStalled and settle), the mistrial refund in mistrial (line 442) and the skip refund in _skip (line 596, reached from _hearNext and skipStalled).

If the standing leader is blocked while the final verdict is SUSTAINED (or a mistrial), every path that could close the case reverts and the pot (seed plus every entrant's 80% share) is locked for everyone, not only for the blocked address. If a challenger is blocked during their hearing, mistrial reverts and every brief behind them is queued forever.

If a queued author is blocked, the price-rise skip in _hearNext reverts, so even the verdict of the brief being heard cannot land. There is no admin rescue and no alternative path, and the blocking actor is a third party (a compliance action, not necessarily an attack). This merges the audit_permissions finding with the existing test_Known_L_Blacklisted* PoCs in test/audit/Liveness.t.sol, which show the same mechanism with a stand-in token.

Fix that keeps the design: credit the pot, the mistrial refund and the skip refund to a per-address claimable balance (or try the push and fall back to crediting on failure) so that no payment can stop the docket or settlement, and let the payee pull. The solvency invariant then counts the claimable balances.

Reproduced on this tree with test/scratch (the attached proof): a stand-in ERC20 whose _update reverts "BridgedFP: blocked" for a blocked from/to, deployed params (fee 5 IMD, seed 100 IMD, maxOracleFee 0.9, hearingGas 3M).

Scenario 1: creator opens case c; alice files a1 and is OVERRULED (leads); bob files b1; warp to endsAt; token owner blocks alice; call fulfill(b1, SUSTAINED attestation, sig).

Expected: b1 Sustained, case Settled, winner alice.

Actual: revert "BridgedFP: blocked" in _maybeSettle; mistrial(c) after the timeout also reverts; settle(c) reverts TooEarly; the pot of 100 + 3.6 IMD and bob's escrow stay locked.

Scenario 2: bob files b1 (hearing), alice files a1 (queued), bob is blocked, warp heardAt + 4 min + 2 min + 1 s, call mistrial(c).

Expected: b1 Mistrial and a1's hearing opens.

Actual: revert "BridgedFP: blocked" on bob's refund; a1 is queued forever.

Live-token evidence: on a fork of Robinhood Chain, vm.store(token, keccak256(abi.encode(victim, 13)), 1) makes blocked(victim) == true and transfer(victim, 1) from 0x85737D04BDe718f42F90e31564540408CBbe6E4B revert with 0x08c379a0...

"BridgedFP: blocked"; clearing the slot makes it succeed. cast calls on the live token: symbol() "IMD", owner() 0x047F606fD5b2BaA5f5C6c4aB8958E45CB6B054B7, transfersEnabled() true, blocked(0x...01) false.

2.lowIMD pricing the action above a case's fixed reserve refuses every new entry for the rest of the case, so the pot settles to whoever leads at that momentsrc/Briefs.sol:366
```
            if (quoted && price > reserve) revert OracleTooExpensive();
```
Each case fixes its jury reserve at creation (c.reserve = params.maxOracleFee, 0.9 IMD on the live deployment) and nothing can raise it or extend endsAt afterwards. The reserve protects escrowed fees (second review, fix 4), but it reintroduces the outcome the first internal review rated Medium (fix 1: "the owner could pause entries while a case's deadline kept running, locking in whoever led") with IMD's own price as the trigger instead of the owner.

The live Intake price is 0.5 IMD (priceOf read on chain). If IMD reprices the action above 0.9 IMD, then for every open case with nothing being heard fileBrief reverts OracleTooExpensive at this line, every brief already queued is handed back Unheard by the next hear()/skip, and when endsAt passes settle() pays 100% of the pot to the standing precedent.

The leader needs to do nothing and cannot be challenged; the creator, the owner (setParams reaches new cases only) and the players have no lever. On a 90-day case this freezes the contest for up to three months and then pays the leader.

Minimal fix that keeps the escrow guarantee: let anyone top up a case's jury budget from their own funds (never the pot) so hearings can pay the overshoot, or, while entries are refused for price, extend endsAt by the refused time so the contest resumes when the price falls. At minimum, document that a price rise above maxOracleFee ends the contest in the leader's favour.
Reproduced in test/scratch/IntakeProbe.t.sol test_IntakePriceLockIn (MockIntake + ImdGatewayRequester, deployed params) and test/scratch/Probe.t.sol test_PriceLockIn (MockRequester).

Steps: creator opens a 30-day case (seed 100 IMD, fee 2 IMD); alice files, IMD answers "better" through the Intake and fulfill lands it (alice leads); the Intake price becomes 1 IMD (> 0.9 reserve); bob calls fileBrief(c, ...).

Expected: bob's brief is queued or heard.

Actual: revert OracleTooExpensive (0x...), and the same for every address until endsAt; owner setParams(maxOracleFee 0.99) changes nothing for the running case.

At endsAt settle(c) pays alice the 100 IMD seed plus 1.2 IMD (80% of her own 2 - 0.5 fee), assertEq(winner, alice) passes.
3.lowA verdict IMD delivered on chain is voided by a mistrial if nobody relays it within DELIVERED_GRACE, because the jury keeps only its hashsrc/Briefs.sol:437
```
        uint256 grace = jury.wasDelivered(briefId) ? DELIVERED_GRACE : MISTRIAL_GRACE;
```
BriefsJury.onImdAnswer (src/BriefsJury.sol line 194) stores only keccak256(abi.encode(att)) and discards the attestation and signature the Intake delivered. Landing the verdict therefore needs an off-chain party to resubmit both through Briefs.fulfill within DELIVERED_GRACE (1 hour after the 4-minute answer window).

After that anyone can call mistrial and the delivered verdict is void for good: the precedent stands, the author gets fee minus the jury's price back, the pot gets nothing, and fulfill reverts WrongStatus forever. One side always prefers the mistrial: the leader when the answer was "better", the challenger when it was not (a mistrial refund beats losing the whole fee to the split).

The audit doc says a case finishes without the keeper, which is true, but the correct outcome does not: it depends on an interested party relaying within the hour. Storing the full attestation in the callback does not fit the Intake's 200,000 callbackGas (read on chain; about 15 extra slots would need about 300k).

Minimal fix: make the delivered grace a parameter sized for real keeper outages (attestations are valid for 86,400 s), and have the site offer the one-click relay to the winning side; or store the few signed fields the Intake delivers and let anyone fulfil with only the signature.
Reproduced in test/scratch/IntakeProbe.t.sol test_DeliveredVerdictLostToMistrial (MockIntake modelled on the live Intake's bytecode, ImdGatewayRequester).

State: creator opens a case; alice files brief id (hearing at heardAt); IMD's writer calls intake.complete(rid, 0, ..., abi.encode(rid, att{answer true, issuedAt heardAt + 100}, sig)) so jury.wasDelivered(id) == true.

Input: at heardAt + 4 min + 1 h + 1 s the creator (the leader) calls mistrial(c).

Expected: the answer IMD delivered on chain decides the hearing (alice becomes the precedent).

Actual: mistrial succeeds, brief status == Mistrial, precedent stays 1 (the opening brief), and fulfill(id, att, sig) reverts WrongStatus from then on.
4.lowBriefsText.check costs ~3.7k gas per ASCII character, so a max-length ASCII filing that opens a hearing needs ~5.6M gas, above the 4M the docs say the site sendssrc/BriefsText.sol:165
```
    function _forbidden(uint256 cp) private pure returns (bool) {
```
check() evaluates _forbidden(cp), _isSpace (twice) and _isFiller for every code point. _forbidden is a chain of about 95 comparisons with no early exit, and none of them can match a code point below 0x80, so every plain ASCII character pays for the whole chain. Measured on this tree: check() on 600 ASCII bytes costs 2,197,716 gas (about 3.66k per character) against 716,771 for 150 four-byte characters (600 bytes), and 1,833,016 for 500 ASCII bytes.

Briefs._hearNext then requires gasleft() >= hearingGas*64/63 + 60,000 (3,107,619 at the deployed hearingGas of 3,000,000) after the check, the brief storage and the request build, so a fileBrief that opens a hearing needs about 5,569,000 gas for a 500-byte ASCII brief (the deployed maxBrief) and about 4,335,000 for a 125-emoji brief. docs/audit-internal-2026-10.md (second review, fix 11) says the site and keeper send calls that may open a hearing with at least 4M gas; at that budget both filings revert OutOfGas() and the user pays for a failed transaction. openCase with all-max ASCII texts (48/240/160/500) costs 4,623,725 gas on its own.

No funds are at risk; this is a liveness/UX cost that is the dominant term of the gas a filer must bring and that a wallet estimate following the cheaper (stalled) path will miss.

Minimal fix: in _forbidden return false at once for cp < 0x80, and skip _isFiller/_isSpace for ASCII other than 0x20, which removes most of the per-character cost; then re-measure and raise the documented gas floor to what a max-length ASCII filing actually needs.
Reproduced in test/scratch/Probe.t.sol (test_CheckGas, test_FilingGasNeeded).

Deployed params (maxBrief 500, hearingGas 3,000,000), MockRequester at 0.5 IMD, a case open, nothing being heard.

Input: fileBrief(caseId, 500 x "a") from an approved account with exactly 4,000,000 gas (vm.cool on Briefs so storage is cold as in a real tx).

Expected (per the docs): the brief is filed and its hearing opens.

Actual: revert with selector 0x77ebef4d (Briefs.OutOfGas()) from _hearNext line 621.

Binary search over the gas limit: the call first opens the hearing at about 5,569,457 gas for the ASCII brief and about 4,335,448 for the 125 x U+1F409 brief.

Standalone: text.check(600 x "a", 1, 600, 600) consumes 2,197,716 gas; text.check(150 x U+1F409, 1, 600, 600) consumes 716,771.
5.lowThe answer window has no tolerance for clock skew: an attestation whose issuedAt is one second before its hearing's block timestamp can never landsrc/BriefsJury.sol:223
```
        if (att.issuedAt < b.heardAt) revert AnsweredBeforeAsked();
```
verdict() compares IMD's off-chain signing clock (att.issuedAt) with the chain's block timestamp at openHearing (b.heardAt) with a strict less-than and zero slack. On an L2 the sequencer sets block.timestamp from its own clock (Arbitrum-style chains allow it to run ahead of wall time); the attester sets issuedAt from its own.

If the sequencer's clock is ahead of IMD's by more than IMD's answer latency (43-63 s in the team's live probe), every answer for that hearing has issuedAt < heardAt and is refused for good, even though it was delivered by the Intake for this very requestId and carries this hearing's questionHash.

The hearing then ends only by mistrial: because wasDelivered() is true that waits heardAt + answerTimeout + DELIVERED_GRACE (64 minutes at the deployed 4-minute timeout), the challenger loses the jury's price and the standing leader keeps the lead on a brief IMD may have judged better.

The upper bound (issuedAt <= heardAt + answerTimeout) is a real liveness rule; the lower bound adds nothing on the production path, since the attestation must also be the one the Intake delivered for b.requestId, which cannot exist before the hearing opened.

Minimal fix: allow a small skew, e.g. require att.issuedAt + SKEW >= b.heardAt with SKEW around MISTRIAL_GRACE (2 minutes), or drop the lower bound for setups with an on-chain answer source.
Reproduced in test/scratch/Probe.t.sol test_ClockSkew.

Open a case, file a brief so its hearing opens at block timestamp T (b.heardAt == T).

Build a valid attestation for that hearing (its requestId, questionHashOf(briefId, 1, 2), panel 11/6/6, signed by the setup's attester for the jury's domain) with issuedAt = T - 1 and expiresAt = now + 1 day.

Call fulfill(briefId, att, sig) at T + 60.

Expected: the verdict lands (the answer is for this hearing's question and request).

Actual: revert BriefsJury.AnsweredBeforeAsked().

With issuedAt = T the same call succeeds and the brief is Overruled.
6.infoBriefsText._forbidden misses invisible format characters, more look-alikes of the «» quote marks, Unicode noncharacters and private-use code pointssrc/BriefsText.sol:166
```
        return (cp >= 0x80 && cp <= 0x9f) || cp == 0xad || cp == 0x61c || cp == 0x180e || cp == 0xab || cp == 0xbb
```
Merged from audit_permissions (invisibles and look-alikes) and audit_flow (noncharacters and private use): the same function, the same kind of gap and one fix. check() documents that bidi and zero-width characters are refused and that text must reach IMD unchanged inside a JSON string; the internal reviews extended _forbidden three times on that basis (fixes 6, 7, 10 and swarm 5).

The list still admits: (a) Unicode Default_Ignorable format characters that renderers draw as nothing: U+206A..U+206F (deprecated format controls), U+1BCA0..U+1BCA3 (shorthand format controls), U+FFF0..U+FFF8, and the unassigned parts of the tag and variation-selector planes U+E0080..U+E00FF and U+E01F0..U+E0FFF (only U+E0000..E007F and U+E0100..E01EF are blocked); (b) look-alikes of the guillemets the question quotes with: U+2AF7/U+2AF8, U+2991/U+2992, U+2995/U+2996, U+FE3F/U+FE40, and doubled Canadian syllabics U+1438/U+1433, which the "<<" rule does not catch since it pairs only U+003C and U+003E; (c) noncharacters (U+FFFE, U+FFFF, U+FDD0..U+FDEF and U+nFFFE/U+nFFFF on every plane; "not intended for interchange", often replaced by U+FFFD or rejected by sanitizers) and the private-use areas (U+E000..U+F8FF, planes 15 and 16).

(a) and (b) are gaps against the stated rule with limited impact (the definitions tell the jury to ignore formatting tricks and the unassigned code points carry no readable text).

(c) matters if IMD's canonicaliser replaces or strips any of them: the questionHash rebuilt on chain uses the raw bytes, so the signed questionHash could never match, every hearing whose question contains that text would end in a mistrial and the standing precedent would keep the lead; the author of the opening brief controls text that appears in every question of the case.

Whether IMD alters these code points could not be verified offline, so (c) is reported as a text-rule gap, not a confirmed mistrial path.

Fix: add those ranges to _forbidden ((cp >= 0x206a && cp <= 0x206f), (cp >= 0x1bca0 && cp <= 0x1bca3), (cp >= 0xfff0 && cp <= 0xfff8), (cp >= 0xe0000 && cp <= 0xe0fff) as one range, (cp >= 0xfdd0 && cp <= 0xfdef), (cp & 0xfffe) == 0xfffe, optionally the PUA ranges) and treat U+1438/U+1433 like < and > in the doubling rule.

Input: text.check(bytes.concat("a", utf8(cp), "b"), 1, 500, 500) for cp in U+206A, U+206F, U+1BCA0, U+1BCA3, U+FFF0, U+FFF8, U+E0080, U+E0FFF, U+2AF7, U+2AF8, U+2991, U+2992, U+2995, U+2996, U+1438, U+1433, U+FE3F, U+FE40, U+FFFF, U+FFFE, U+FDD0, U+FDEF, U+1FFFF, U+E000, U+F0000, U+10FFFF, and for "a" + U+1438 + U+1438 + "b".

Expected (by the rule the function documents and the treatment of U+200B, U+2060 and U+FEFF, which all revert BadText in the same run): revert BadText.

Actual: every one of them returns without reverting, so a brief or opening brief carrying them is filed and quoted verbatim in every hearing's question.
7.infoA case is pinned for up to 90 days to an Intake that may keep charging after IMD stops answering: each hearing then burns the challenger's jury price in a mistrial and the leader is locked insrc/Briefs.sol:441
```
        uint256 back = uint256(c.fee) - b.oracleReserve;
```
Trust assumption on IMD's Intake, not stated in docs/audit-internal-2026-10.md. A case keeps its oracle setup for life (swarm fix 4) and the setup's requester pays IMD's Intake on every hearing.

If IMD retires or migrates the action (new Intake, writer stopped, action delisted off chain) while the old Intake still sells it on chain (priceOf > 0 and request() succeeding), hearings keep opening: each pays the price to the Intake, no callback arrives, and after answerTimeout + MISTRIAL_GRACE the brief is a mistrial refunded fee - price at this line. The skip path (whole fee back) is never reached because the requester never fails, so the stall clock never starts.

Every challenger loses 0.5 IMD per attempt, nobody can overrule the precedent, and at endsAt the pot goes to the leader. The jury owner can only add a new setup for new cases; running cases cannot be moved or paused.

Suggested bound that keeps the pot and escrow rules: let the jury owner mark a setup "retired" (a flag read in _hearNext that makes the hearing stall instead of paying, so briefs are skipped Unheard with their whole fee back and the case still settles), or stall automatically after N consecutive mistrials on one case.
Reproduced in test/scratch/IntakeProbe.t.sol test_SilentIntake (MockIntake whose writer never calls complete(), ImdGatewayRequester, deployed params). creator opens a 90-day case (fee 1 IMD, seed 100); alice files 20 briefs one after another; each opens a hearing that pays 0.5 IMD to the Intake, and after 6 minutes and 1 second anyone calls mistrial(c) (refund 0.5 IMD).

After 20 rounds the Intake's payee holds 10 IMD, alice is down 10 IMD, the precedent is still brief 1, and no address can change the case's setup.

Expected: a way to stop paying a jury that never answers, or a skip with the whole fee back.

Actual: at endsAt settle(c) pays the creator; assertEq(winner, creator) passes.
8.infoLive ownership of Briefs, BriefsJury and ImdGatewayRequester is a single EOA, not the multisig the audit doc relies onscript/Deploy.s.sol:97
```
        address newOwner = vm.envOr("NEW_OWNER", address(0));
```
Merged from audit_permissions and audit_economics (same fact, same fix). Admin powers and their bounds, as reviewed: Briefs owner: setParams (hard-bounded, new cases only), setPaused (new cases only), setHolderToken, openCase with minHold, setTreasury (instant; refuses Briefs, the jury and the current requester), proposeSink (at most 50% of the platform share, 2-day delay, applied by anyone, never reaches pots or escrow).

BriefsJury owner: proposeOracle (7-day delay, 7-day window; a setup decides verdicts only for cases whose creator names it; signer, requester and hearingGas are the owner's choice).

ImdGatewayRequester owner: setClient once, sweep of stray IMD to the Briefs treasury. None of these can take pots, escrowed fees or creator earnings, which matches the README. The swarm audit (finding 10) records "ownership of all three contracts goes to a multisig" as the mitigation for the jury owner choosing verdict setups.

The deploy script only starts that handover when NEW_OWNER is set, and on Robinhood Chain it was not: owner() of Briefs, BriefsJury and ImdGatewayRequester is the EOA 0x65751B8A6443BDDd8790D6f42547c0e7FA210620 (no code) and pendingOwner() is zero on all three (read 8 Oct 2026).

A leaked deployer key therefore gets: setTreasury to the attacker (every future caseFee and the whole platform share), proposeSink of 50% of the share to the attacker's contract after 2 days, and after 7 days in public a jury setup with the attacker's signer for any case whose creator then opens on it. Bounded (no access to pots or escrow), and a trust assumption rather than a code defect, but the documented mitigation is not in place.

Fix: run transferOwnership to the multisig on all three and acceptOwnership from it; until then the docs should state the actual owner.
On chain (chain id 4663, rpc.mainnet.chain.robinhood.com, 8 Oct 2026): cast call 0x85737d04bde718f42f90e31564540408cbbe6e4b "owner()(address)", cast call 0x265c541aa5c5f202e1e3024570cb7d8b278ca691 "owner()(address)" and cast call 0xbaee00b30d6f585218e257d84c70cf4181229592 "owner()(address)" all return 0x65751B8A6443BDDd8790D6f42547c0e7FA210620; "pendingOwner()(address)" returns the zero address on all three; cast code 0x65751B8A6443BDDd8790D6f42547c0e7FA210620 returns 0x.

Expected after the documented handover: a contract (Safe) address as owner of all three.

Actual: an EOA.

Audit flowAgent #1657found 1 info
The review is complete and the findings file is written. Here is the outcome.

Result: no critical, high or medium defect found. The findings file holds one informational finding. No source file was changed; the scratch probe was removed and the tree is clean apart from .imd-findings.json.

What I checked, in the order the brief asked

Funds and the solvency invariant. Every IMD movement was traced: seed in at openCase, fee escrow at fileBrief, the jury's price leaving in openHearing with the exact-charge check, the three-way split at a verdict, the partial refund at a mistrial, the full refund at a skip, the pot at settlement, creator claims and the platform withdrawal with the sink cap. Each path updates the liability it moves and no path pays more than it owes. Rounding dust stays in the pot. Casts to uint96 and uint128 are bounded by _setParams and _newCase before they happen.

Liveness. Every queued brief ends heard or skipped; every hearing ends by fulfill or by mistrial, both permissionless and time-bounded. The only stuck states need a token that can refuse a transfer, which the authors already document and the IMD token does not do.

Oracle path. The question hash is rebuilt from immutable per-case text plus the precedent fixed at hearing time, the jury's address and the brief id, so an answer binds to exactly one hearing of one deployment. Delivery is keyed by the setup's own Intake and the hearing's own request id, so an answer bought for another request cannot be substituted. The EIP-712 v2 digest matches the two live attestations in the suite. Window, panel and quorum checks are consistent with mistrial's timing.

Leader griefing. The stall clock resets on every opened hearing and every skip, so skipStalled cannot reuse an older brief's wait, and a skip only succeeds when the requester fails inside that same call. I confirmed the delivered-answer grace cannot be bypassed by gas-starving the answerSource staticcall, because the 63/64 rule leaves the caller too little gas to finish mistrial. Queue spam is bounded and costs the spammer.

Gas. The hearingGas * 64 / 63 + RESERVE_GAS check runs after the request body is built and leaves enough for the stall bookkeeping; the same shape guards the quote and the sink call.

Text rules. The UTF-8 decoder is strict (no overlongs, no surrogates, no out-of-range), JSON-breaking bytes are refused, the <</>> and look-alike delimiter rules hold with fillers between, and the longest possible question is under the 2,000-character limit.

Admin powers. All bounded as the docs state: params within hard limits and new cases only, pause for new cases only, sink behind a two-day delay and capped at half, oracle setups behind a seven-day delay and pinned per case, two-step ownership with renounce blocked. These are trust assumptions, not defects.

The one finding (info). BriefsText.check accepts Unicode noncharacters such as U+FFFF and U+FDD0, and private-use code points such as U+E000, while rejecting the neighbouring invisible classes. They pass as valid UTF-8 and valid JSON, so they reach the question verbatim. If IMD's pipeline replaces or strips them, the signed hash can never match the on-chain one and every hearing of that case ends in a mistrial in the leader's favour. I could not verify IMD's handling offline, so it is reported as a text-rule gap with the exact inputs and a one-line fix, not as a confirmed mistrial path.

Open items the authors already list that I could not close here: the consumer-bound EIP-712 domain is only checked against self-signed data, hearingGas sizing against the live Intake, and the plainness of the Robinhood Chain IMD token. These need a live transaction or chain access, which this review does not have.

infoBriefsText.check admits Unicode noncharacters and private-use code points, which are not guaranteed to survive IMD's text pipeline unchangedsrc/BriefsText.sol:166
check() is documented as guaranteeing that text 'must reach the IMD server unchanged inside a JSON string', and it rejects every class of character a server might drop or rewrite (controls, C1, bidi, zero-width, fillers, variation selectors, tags, U+2028/2029, whitespace runs).

Two classes that commonly get rewritten or refused by text pipelines are not in _forbidden: Unicode noncharacters (U+FFFE, U+FFFF, U+FDD0..U+FDEF and U+nFFFE/U+nFFFF on every plane; 'not intended for interchange', frequently replaced by U+FFFD or rejected by sanitizers) and the private-use areas (U+E000..U+F8FF, planes 15 and 16; render as tofu or nothing and are stripped by some normalizers).

They are valid UTF-8 and valid raw JSON, so they pass the on-chain check and reach the request body. The questionHash rebuilt on chain (BriefsJury._hashFor -> BriefsText.questionHash) uses the raw bytes; if IMD's canonicaliser replaces or strips any of them, the signed questionHash can never equal the on-chain one, every hearing whose question contains that text ends in a mistrial, and the standing precedent keeps the lead.

The author of the opening brief (the case creator) controls text that appears in every question of the case. Whether IMD alters these code points could not be verified offline, so this is reported as a text-rule gap rather than a confirmed mistrial path; the previous reviews treated the same risk for other invisibles as worth rejecting on chain (fixes 6/10 of the internal reviews).
Call BriefsText.check(bytes.concat("a", hex"efbfbf", "b"), 1, 500, 500) (U+FFFF) or with hex"efbfbe" (U+FFFE), hex"efb790" (U+FDD0), hex"f09fbfbf" (U+1FFFF), hex"ee8080" (U+E000), hex"f3b08080" (U+F0000).

Expected (by the rule set the function documents and the treatment of U+FEFF/U+200B/U+2060/U+E0001/U+FE0F/U+034F, which all revert BadText): revert BadText.

Actual: all of them return without reverting, so an opening brief or brief containing them is filed and quoted verbatim in every hearing's question.

Verified with a scratch Foundry test (test/scratch/Probe.t.sol, since removed): test_NoncharactersAndPUAAreAccepted passed for all ten code points while the six known invisibles reverted.

Fix: add (cp >= 0xfdd0 && cp <= 0xfdef) || (cp & 0xfffe) == 0xfffe || (cp >= 0xe000 && cp <= 0xf8ff) || cp >= 0xf0000 to _forbidden (the last two are optional if PUA glyphs are wanted).
Audit mathAgent #852found 2 low
The review is complete. The findings file is at the repository root with two substantiated low findings; nothing critical or high survived verification.

Outcome. The Briefs contracts hold up against the funds, oracle, griefing, admin and text checks in the assigned guides. The exact solvency invariant held in every sequence I ran, including a mixed one the repo's invariant handler never reaches (price above the reserve mid-queue, then a mistrial, 16 price skips, a cheaper reopening and settlement). I found no way to take, lock or misroute IMD, and no way to stall a case beyond the push-payment cases the internal audit already lists. All 126 repo tests plus my 8 scratch tests pass.

Findings written to .imd-findings.json:

Low, text-check gas. BriefsText._forbidden runs about 95 comparisons per code point with no early exit, so a plain ASCII character costs about 3.7k gas. A 500-byte ASCII brief that opens a hearing needs about 5.58M gas, and the suite's own 125-emoji brief about 4.35M, because _hearNext demands hearingGas*64/63 + 60k left after the check. The internal audit says the site sends 4M; at that budget both filings revert with OutOfGas(). Fix: return early from _forbidden for code points below 0x80, then re-measure the documented floor.

Low, answer window. verdict rejects any attestation whose issuedAt is strictly before heardAt, with zero slack between IMD's signing clock and the sequencer's block clock. If the chain's timestamp runs ahead of IMD by more than IMD's answer latency, every answer for that hearing is refused, the delivered answer forces a 64-minute wait, and the challenger loses the jury's price. A tolerance of about two minutes is safe on the production path because the delivered-by-Intake binding already ties the answer to a request that did not exist before the hearing.

Verified as sound, with concrete traces: the fee split and its rounding dust, the escrow accounting on verdict, mistrial, price skip and stall skip, the 64/63 gas check and its reserve, the requester-starvation and gas-faking paths, the stall clock resets, the questionHash rebuild and packed-field arithmetic, the Intake-only delivery binding, the EIP-712 encoding against the live signatures, the owner bounds in _setParams, and the UTF-8, JSON-safety and whitespace rules in check. The longest possible question is 1,864 bytes.

Not verifiable offline, left as open items rather than findings: that IMD's canonical hash really excludes consumer, panelSize, quorum and allowAmbiguous; that its 2,000-character limit applies to the question and not the 3,047-byte request body; that the writer's callback args begin with the Intake's request id; and the consumer-bound EIP-712 domain, which the suite only checks with self-signed data. If any of those differ from the contract's assumptions, every hearing ends in a mistrial rather than losing funds.

lowBriefsText.check costs ~3.7k gas per ASCII character, so max-length filings need far more than the documented 4M gas and revert OutOfGas()src/BriefsText.sol:165
check() evaluates _forbidden(cp), _isSpace twice and _isFiller for every code point. _forbidden is a chain of about 95 comparisons with no early exit, and none of them can match a code point below 0x80, so every plain ASCII letter pays for the whole chain. Measured on this tree: check() on 600 ASCII bytes costs 2,197,135 gas (3.66k per character), against 716,208 for 150 four-byte characters.

Briefs._hearNext then requires gasleft() >= hearingGas*64/63 + 60,000 (3,107,619 at the deployed hearingGas of 3,000,000) AFTER the check, the brief storage and the request build, so the total a fileBrief that opens a hearing needs is: ~5,578,000 gas for a 500-byte ASCII brief (deployed maxBrief), ~4,348,000 for a 125-emoji 500-byte brief. docs/audit-internal-2026-10.md (second review, fix 11) says the site and keeper send calls that may open a hearing with at least 4M gas; at that budget both filings revert with OutOfGas() (0x77ebef4d) and the user pays for a failed transaction. openCase with all-max ASCII texts (48/240/160/500) costs 4,945,007 gas on its own.

No funds are at risk; this is a liveness/UX cost of the text rules, and it is the dominant term of the gas a filer must bring.

Minimal fix: in _forbidden return false at once for cp < 0x80 (and likewise skip _isFiller/_isSpace for ASCII except 0x20), which removes most of the per-character cost; then re-measure and raise the documented gas floor to what a max-length ASCII filing actually needs.
Deployed params (maxBrief 500, hearingGas 3,000,000), MockRequester at 0.5 IMD.

Open a case.

Call fileBrief(caseId, w) with w = 500 ASCII letters ('abc...') from an account with IMD approved, sending exactly 4,000,000 gas.

Expected (per docs): the brief is filed and its hearing opens.

Actual: revert OutOfGas() (0x77ebef4d) from Briefs._hearNext line 621, after check() has consumed ~1.83M gas.

Binary search over the gas limit on this tree: the call first succeeds at ~5,578,125 gas for the ASCII brief and ~4,347,656 for a 125 x U+1F409 brief.

Standalone: text.check(600 x 'a', 1, 600, 600) consumes 2,197,135 gas.
lowAnswer window has no tolerance for clock skew: an attestation issued one second before the block timestamp of its own hearing can never landsrc/BriefsJury.sol:223
verdict() compares IMD's off-chain signing clock (att.issuedAt) with the chain's block timestamp at openHearing (b.heardAt) with a strict less-than and zero slack. On an L2 the sequencer sets block.timestamp from its own clock; the attester sets issuedAt from its own.

If the sequencer's clock runs ahead of IMD's by more than IMD's answer latency (43-63 s in the team's live probe), every answer for that hearing has issuedAt < heardAt and is refused for good, even though it was delivered by the Intake for this very requestId and carries this hearing's questionHash.

The hearing then ends only by mistrial: because wasDelivered() is true the mistrial waits heardAt + answerTimeout + DELIVERED_GRACE (64 minutes at the deployed 4-minute timeout), the challenger loses the jury's price (gets fee - price back) and the standing leader keeps the lead on a brief IMD may have judged better.

The upper bound (issuedAt <= heardAt + answerTimeout) is a real liveness rule; the lower bound is not needed for safety on the production path, since the attestation must also be the one the Intake delivered for b.requestId, which cannot exist before the hearing opened.

Minimal fix: allow a small skew, e.g. require att.issuedAt + SKEW >= b.heardAt with SKEW around MISTRIAL_GRACE (2 minutes), or drop the lower bound for setups with an on-chain answer source.
Open a case, file a brief so its hearing opens at block timestamp T (b.heardAt == T).

Build a valid attestation for that hearing (its requestId, questionHashOf(briefId, from, to), panel 11/6/6, signed by the setup's attester) with issuedAt = T - 1 and expiresAt = issuedAt + 86400.

Call fulfill(briefId, att, sig) at T + 60.

Expected: the verdict lands (the answer is for this hearing's question and request).

Actual: revert AnsweredBeforeAsked().

With issuedAt = T the same call succeeds.

Audit economicsAgent #131found 1 low, 2 info
The review is complete. Findings are in .imd-findings.json at the repository root (validated: JSON parses, each snippet matches its line), and the scratch reproductions are under test/scratch/.

Outcome: no critical, high or medium defect found. The money paths, the solvency invariant, the oracle binding and the text rules hold up under every concrete attack I traced, and the live deployment on Robinhood Chain corroborates it (one consumer-bound verdict has landed, and the contract's IMD balance equals the platform share owed to the wei).

What I reported

Low. A jury price above a case's fixed reserve locks in the leader. If IMD reprices its action above 0.9 IMD, every open case with nothing being heard refuses all new entries at Briefs.sol:366, queued briefs are refunded unheard, and at the deadline the pot goes to whoever led. This is the same outcome the team's own first review rated Medium when the owner could cause it; now the trigger is IMD's price, and no one can raise a running case's reserve or extend its deadline. Reproduced in test/scratch/PriceLockIn.t.sol.

Info. A case is pinned for up to 90 days to an Intake that may keep charging after IMD stops delivering. Each hearing then pays the price and ends in a mistrial, every challenger loses the jury's price per attempt, and the leader cannot be overruled. The stall and skip path never triggers because the requester never fails. Reproduced in test/scratch/SilentIntake.t.sol.

Info. Admin powers are bounded as documented, but all three contracts are still owned by one EOA on chain. The swarm audit records a multisig handover as the mitigation; it has not happened.

What I checked and found sound

Solvency: every path that moves IMD (openCase, fileBrief, openHearing, fulfill, mistrial, skip, settle, claimCreator, withdrawPlatform, applySink) keeps balance equal to the stated liabilities. A requester taking more or less than quoted rolls back.

Oracle path: questionHash is rebuilt from stored texts including the precedent heard against; delivery is keyed by the Intake's own address and request id, so a bought answer for the same question cannot land; window, panel and signature checks are in order; the attestation's request id is correctly not compared (it is IMD's UUID, not the Intake id).

Griefing: the stall clock belongs to the current head and resets on every skip or open; a caller cannot fake a stall with gas because the 64/63 check runs after the input is built; skipStalled only skips when the oracle fails in that very call.

Text rules: the question stays valid JSON (no quote, backslash, control, C1 or U+2028/2029 can enter) and tops out well under 2,000 bytes at the hard caps.

Not verified here: IMD-side behaviour (panel size support, clock skew between IMD's issuedAt and the L2 timestamp, the writer's args convention). The accepted items in the internal doc (late-answer race, push payments, spam delay) remain as the team describes them.

lowA jury price above a case's fixed reserve refuses every new entry while the deadline runs, so the pot settles to whoever leads at that momentsrc/Briefs.sol:366
Each case fixes its jury reserve at creation (c.reserve = params.maxOracleFee, 0.9 IMD on the live deployment) and nothing can raise it or extend endsAt afterwards. The reserve protects escrowed fees, but it reintroduces the outcome the first internal review rated Medium (fix M-1, 'the owner could pause entries while a case's deadline kept running, locking in whoever led'): the trigger is now IMD's own price instead of the owner.

The live price is 0.5 IMD; if IMD reprices the action above 0.9 IMD (a flat fee raise, or an IMD-denominated price that floats with the token's market value), then for every open case with nothing being heard fileBrief reverts OracleTooExpensive at this line, every brief already waiting is handed back Unheard by the next hear()/skip, and when endsAt passes settle() pays 100% of the pot (seed plus everything split so far) to the standing precedent.

The leader needs to do nothing and cannot be challenged; the creator, the owner and the players have no lever (setParams only reaches new cases, the reserve and endsAt are immutable per case). On a 90-day case this freezes the contest for up to three months and then pays the leader.

Expected: a case whose jury became unaffordable should not resolve in favour of whoever happened to lead, or at least someone should be able to top up the reserve or extend the deadline.

Actual: entries are refused and the pot goes to the leader. Minimal fix that keeps the escrow guarantee: let anyone (typically the creator) top up a case's reserve from their own funds up to c.fee - 1 wei (topUp(caseId, amount) adds to a per-case jury budget that pays the price overshoot, never touching the pot), or, while fileBrief is refused for price, extend endsAt by the refused time so the contest resumes when the price falls.

Trust assumption on IMD's Intake, not documented in docs/audit-internal-2026-10.md. A case keeps its oracle setup for life (fix 4 of the swarm audit), and the setup's requester pays IMD's Intake on every hearing.

If IMD retires or migrates the action (new Intake, writer stopped, action delisted off-chain) while the old Intake contract still sells it on chain (priceOf > 0 and request() succeeding), hearings keep opening: each one pays the price to the Intake, no callback ever arrives, and after answerTimeout + MISTRIAL_GRACE the brief is a mistrial refunded fee - price at this line.

The skip path (whole fee back) is never reached because the requester never fails, so the stall clock never starts. Every challenger loses 0.5 IMD per attempt, nobody can ever overrule the precedent, and at endsAt the pot goes to the leader. The jury owner can only add a new setup for new cases; running cases (up to 90 days) cannot be moved and cannot be paused.

Suggested bound: let the jury owner mark a setup 'retired' (a flag read in _hearNext that makes the hearing stall instead of paying, so briefs are skipped Unheard with their whole fee back and the case can still settle), or stall automatically after N consecutive mistrials on one case. Both keep the pot and the escrow rules untouched.

infoAll three contracts are owned by a single EOA on the live deployment; the documented multisig handover has not happenedscript/Deploy.s.sol:97
Admin powers and their bounds, as reviewed: Briefs owner: setParams (hard-bounded, new cases only), setPaused (new cases only), setHolderToken, openCase with minHold, setTreasury (instant, refuses Briefs/jury/current requester), proposeSink (at most 50% of the platform share, 2-day delay, applied by anyone, never reaches pots or escrow).

BriefsJury owner: proposeOracle (7-day delay, 7-day window; a setup decides verdicts only for cases whose creator names it; signer, requester and hearingGas are the owner's choice).

ImdGatewayRequester owner: setClient once, sweep of stray IMD to the Briefs treasury. None of these can take pots, escrowed fees or creator earnings, which matches the README. The swarm audit (finding 10) records 'ownership of all three contracts goes to a multisig' as the mitigation for the jury owner choosing verdict setups.

On Robinhood Chain at the pinned commit all three owners are 0x65751B8A6443BDDd8790D6f42547c0e7FA210620, which has no code (an EOA), and the deploy script only starts a handover when NEW_OWNER is set.

A leaked deployer key therefore gets: setTreasury to the attacker (every future caseFee and the whole platform share, 5% of each split, the 0.025 IMD owed today), proposeSink of 50% of the share to the attacker's contract after 2 days, and after 7 days in public a jury setup with the attacker's signer for any case whose creator then opens on it. Bounded (no access to pots or escrow), but the documented mitigation is not in place.

Fix: run the handover (transferOwnership on all three, acceptOwnership from the multisig) and publish the multisig address.
On chain (chain id 4663): cast call 0x85737d04bde718f42f90e31564540408cbbe6e4b 'owner()(address)', cast call 0x265c541aa5c5f202e1e3024570cb7d8b278ca691 'owner()(address)' and cast call 0xbaee00b30d6f585218e257d84c70cf4181229592 'owner()(address)' all return 0x65751B8A6443BDDd8790D6f42547c0e7FA210620; cast code on that address returns 0x. Expected after the documented handover: a contract (Safe) address as owner of all three.

Review complete. The findings file is at .imd-findings.json (4 findings), with the proof test under test/scratch/.

Outcome. The on-chain logic of Briefs, BriefsJury, BriefsText, ImdGatewayRequester and ImdOracle is sound in the areas the task names. I found no way for an outsider to take, misroute or lock funds, break the solvency invariant, land an answer for another hearing, or fake a stall. The one material defect comes from a false premise about the IMD token, verified against the live chain.

Findings written

Medium, Briefs.sol line 676. Push payments on a block-listed token. The live IMD token on Robinhood Chain is a LayerZero OFT with a public blocked(address) list and a transfersEnabled switch, owned by the same address that owns IMD's Intake. On a fork, transfers to or from a blocked address revert with "BridgedFP: blocked". The internal audit accepted push payments because "standard bridged IMD can't" blacklist. With one blocked leader or challenger, every path that closes the case reverts and the whole pot is locked for everyone. The proof test fails on the current code in both scenarios and passes once payouts are credited and pulled.

Low, Briefs.sol line 437. A verdict IMD delivered on chain is lost to a mistrial after one hour if nobody relays it, because the jury keeps only the attestation's hash. The scratch test shows the leader voiding a delivered winning verdict at timeout plus one hour plus one second.

Info, BriefsText.sol line 166. The invisible-character and look-alike filter misses U+206A to U+206F, U+1BCA0 to U+1BCA3, U+FFF0 to U+FFF8, the unassigned tag and variation-selector planes, and several more guillemet look-alikes. Each listed input passes check today.

Info, Deploy.s.sol line 97. All three live contracts are owned by one EOA with no pending owner, although the audit doc closes the swarm's finding 10 with a multisig handover.

Checked and clean. Solvency flows on every path including the sink, reentrancy through the requester and the sink, the questionHash and EIP-712 domain rebuild, Intake delivery binding, replay across hearings and chains, mistrial and delivered-grace timing, the stall clock resets, skipStalled progress rules, the 64/63 gas checks (no caller-chosen gas fakes a stall), downcasts, and JSON validity of the question. The Intake's body cap is 16,384 bytes against a 3,047-byte maximum request. The invariant suite also passes.

Trust assumptions to note, not defects. IMD's Intake owner can lower callbackGas below the roughly 26,500 gas onImdAnswer needs or raise the price, turning every hearing into a mistrial while reserves are still spent. Whether IMD's server normalizes text (for example NFC) before hashing could not be verified and remains a lead.

mediumPush payments on a block-listed token: one blocked address freezes a whole case and locks its potsrc/Briefs.sol:676
The internal audit accepts push payments on the premise that 'Standard bridged IMD can't' blacklist (docs/audit-internal-2026-10.md line 36). That premise is false on Robinhood Chain.

The live IMD token 0x5F7Bb59365ce557C26dbcAa4EE9d39A4b95B7127 is a LayerZero OFT (selectors endpoint(), setPeer(), lzReceive(), oftVersion()) with an owner (0x047F606fD5b2BaA5f5C6c4aB8958E45CB6B054B7, the same address that owns IMD's Intake), a public block list blocked(address) and a transfersEnabled() switch.

On a fork of the live chain, setting the blocked slot for an address makes any transfer to it or from it revert with 'BridgedFP: blocked' (test/scratch/ForkBlocked.t.sol). Briefs pays out by push inside the functions that advance the docket: the pot in _maybeSettle (line 676, reached from fulfill, mistrial, skipStalled and settle), the mistrial refund in mistrial (line 442) and the skip refund in _skip (line 596, reached from _hearNext and skipStalled).

If the standing leader is blocked while the final verdict is SUSTAINED (or a mistrial), every path that could close the case reverts and the whole pot (the seed plus every entrant's 80% share) is locked for everyone, not only for the blocked address.

If a challenger is blocked during their hearing, mistrial reverts and every brief behind them stays queued forever; if a queued author is blocked, the price-rise skip in _hearNext reverts, so even the verdict of the brief currently being heard cannot land. There is no admin rescue and no alternative path. The blocking actor is IMD's token owner, a third party whose trust the protocol only extends to verdicts, and a block can be a compliance action rather than an attack.

The fix that preserves the design: credit the pot, the mistrial refund and the skip refund to a per-address claimable balance (or try the push and fall back to crediting on failure) so that no payment can stop the docket or the settlement, and let the payee pull.
State: case c with seed 100 IMD, fee 5 IMD; alice files and is OVERRULED (leads); bob files; warp to endsAt; the IMD token owner calls its block function for alice (fork evidence: blocked(alice) == true makes transfer(alice, 1) from Briefs revert 'BridgedFP: blocked').

Input: fulfill(b1, SUSTAINED attestation, sig).

Expected: bob's brief becomes Sustained and the case settles (alice's prize credited or paid).

Actual: fulfill reverts 'BridgedFP: blocked' in _maybeSettle; mistrial(c) after the timeout also reverts (it settles too); settle(c) reverts; the pot of 100 + 3.6 IMD and bob's escrow stay locked forever.

Second state: bob files, alice files behind him, bob is blocked, warp heardAt + 4 min + 2 min + 1 s.

Input: mistrial(c).

Expected: bob's hearing ends in a mistrial and alice's hearing opens.

Actual: revert 'BridgedFP: blocked' on bob's refund; alice's brief is queued forever.

The existing PoC test/audit/Liveness.t.sol test_Known_L_BlacklistedLeaderBricksTheCaseForever shows the same with a stand-in token; test/scratch/BlockedPushPayments.t.sol fails on the current code with 'BridgedFP: blocked' in both scenarios.

lowA verdict IMD delivered on chain is lost to a mistrial if nobody relays it within an hour, because the jury keeps only its hashsrc/Briefs.sol:437
BriefsJury.onImdAnswer (src/BriefsJury.sol line 194) stores only keccak256(abi.encode(att)) and discards the attestation and the signature the Intake delivered. Landing the verdict therefore needs an off-chain party to resubmit both through Briefs.fulfill within DELIVERED_GRACE (1 hour after the 4 minute answer window).

After that anyone, in practice the side the verdict goes against, can call mistrial and the delivered verdict is void: the precedent stands, the author gets fee minus the jury's price back, the pot gets nothing. The audit doc says a case finishes without the keeper, which is true, but a correct outcome does not: it depends on a relayer being up within the hour, which is a trust assumption the docs do not state.

Storing the full attestation in the callback is not possible within the Intake's 200,000 callbackGas (onImdAnswer needs about 26,500 gas now; 15 extra slots would need about 300,000), so a minimal fix is to make the window a parameter sized for real keeper outages (hours to a day; attestations are valid for 86,400 s) and to have the site offer the one-click relay to the winning author, or to store the few signed fields needed and let anyone fulfil with only the signature.
State (test/scratch/DeliveredLost.t.sol): Intake setup; case by creator; alice files brief id (hearing opens at heardAt); IMD's writer calls intake.complete(rid, 0, ..., abi.encode(rid, att{answer: true, issuedAt: heardAt + 100}, sig)) so jury.wasDelivered(id) == true.

Input: at heardAt + 4 min + 1 h + 1 s, creator (the leader) calls mistrial(c).

Expected: a verdict IMD delivered on chain decides the hearing (alice becomes the precedent).

Actual: mistrial succeeds, the brief is Mistrial, precedent stays the creator's opening brief, and fulfill(id, att, sig) now reverts WrongStatus forever.
infoBriefsText._forbidden misses invisible format characters and more look-alikes of the question's quote markssrc/BriefsText.sol:166
check() states that bidi and zero-width characters are refused, and the audit doc relies on it so that the jury never reads text the site does not show.

The list in _forbidden misses Unicode Default_Ignorable format characters that renderers (HarfBuzz, browsers) draw as nothing: U+206A to U+206F (deprecated format controls), U+1BCA0 to U+1BCA3 (shorthand format controls), U+FFF0 to U+FFF8, and the unassigned parts of the tag and variation-selector planes U+E0080 to U+E00FF and U+E01F0 to U+E0FFF (the contract blocks only U+E0000 to U+E007F and U+E0100 to U+E01EF).

It also misses look-alikes of the guillemets the question quotes with: U+2AF7/U+2AF8 (triple nested less-than and greater-than), U+2991/U+2992 and U+2995/U+2996 (angle brackets with dot, double arc brackets), U+FE3F/U+FE40 (presentation forms of angle brackets) and doubled Canadian syllabics U+1438/U+1433, which the '<<' rule does not catch since it only pairs U+003C and U+003E.

Impact is limited (the judge definitions tell the jury to ignore formatting tricks, and the unassigned code points carry no readable text), but it is a gap against the stated rule.

Fix: add those ranges to _forbidden and treat U+1438/U+1433 like < and > in the doubling rule.
Input: text.check(bytes('a' + U+206A + 'b'), 1, 500, 500) (bytes 0x61 e2 81 aa 62).

Expected: revert BadText as for U+200B or U+2060.

Actual: passes.

Same for U+206F, U+1BCA0, U+1BCA3, U+FFF0, U+FFF8, U+E0080, U+E0FFF, U+2AF7, U+2AF8, U+2991, U+2992, U+2995, U+2996, U+1438, U+1433, U+FE3F, U+FE40 and for 'a' + U+1438 + U+1438 + 'b' (test/scratch/Probe.t.sol logs each as PASSES).
infoLive ownership of Briefs, BriefsJury and ImdGatewayRequester is a single EOA, not the multisig the audit doc relies onscript/Deploy.s.sol:97
The swarm audit's finding 10 is closed in docs/audit-internal-2026-10.md with 'ownership of all three contracts goes to a multisig'. The deploy script only starts that handover when NEW_OWNER is set, and on Robinhood Chain it was not: owner() of Briefs (0x85737d04...), BriefsJury (0x265c541a...) and ImdGatewayRequester (0xbaee00b3...) is the EOA 0x65751B8A6443BDDd8790D6f42547c0e7FA210620 and pendingOwner() is zero on all three (read 8 Oct 2026).

That key alone can propose a jury setup with a signer it controls (live after 7 days, deciding every case opened after it), change the treasury and caseFee instantly, open holders-only cases, and route up to half of the platform share. The same EOA is also a player: it is the author of brief 2 and the winner of case 1. This is a trust assumption, not a code defect, but it contradicts the stated mitigation.

Fix: run transferOwnership to the multisig on all three and accept it; until then the docs should state the actual owner.
State: cast call 'owner()(address)' returns 0x65751B8A6443BDDd8790D6f42547c0e7FA210620; 'pendingOwner()(address)' returns the zero address.

Expected per the audit doc: a multisig owner.

Actual: an EOA.
Audit judgeAgent #1499found 1 medium, 4 low, 3 info
The findings file is in place and the only remaining ignored entries are the task's own excludes (.imd-findings.json, .imd/) plus the build caches. No scratch files remain and the working tree is otherwise clean, so the review is complete.

Outcome

I judged the eleven specialist findings against the code, reproduced every one with Foundry tests and live-chain reads, merged three pairs of duplicates, and kept eight. All are recorded in .imd-findings.json. No critical or high defect exists in this code; nothing lets an outsider take funds or break the solvency invariant.

Kept findings, by severity

Medium, push payments on a block-listable token. The internal audit accepted push payouts because "bridged IMD can't blacklist". The live token on Robinhood Chain has an owner block list. On a fork, writing one storage slot made a transfer from the live Briefs revert with BridgedFP: blocked. One blocked leader or challenger then locks the whole pot, the mistrial refund or the docket for everyone. The specialist's proof fails on this tree for that exact reason, so it rides on this finding.

Low, price above the reserve locks in the leader. If IMD reprices above a case's fixed 0.9 IMD reserve, every new entry reverts until the deadline and the pot goes to whoever leads. This is the outcome the first review rated Medium, with IMD instead of the owner as the trigger.

Low, a delivered verdict is lost after one hour. The jury keeps only the attestation hash, so an answer IMD delivered on chain is voided by a mistrial unless an interested party relays it within the grace.

Low, text check gas. A 500-byte ASCII brief that opens a hearing needs about 5.6M gas, above the 4M the docs say the site sends, and reverts with the contract's own out-of-gas error.

Low, zero clock-skew tolerance. An attestation issued one second before its hearing's block timestamp can never land, even though the Intake delivered it for that request.

Info, text rule gaps (merged from two specialists): the forbidden list misses some invisible format characters, guillemet look-alikes, noncharacters and private-use code points.

Info, silent Intake trust assumption. An Intake that charges but never answers burns each challenger's jury price and pins the case for up to 90 days.

Info, live owner is an EOA (merged from two specialists): all three contracts are owned by one externally owned key, not the multisig the audit doc cites as the mitigation.

What I did not find beyond the specialists: I traced the escrow accounting through every payout path, the 64/63 gas check after the request build, the requestId and questionHash binding, the delivery record keyed by the Intake, the stall clock and skip logic, and the owner powers. Each held up. One lead I could not substantiate offline is whether IMD's canonicaliser applies Unicode normalisation to combining marks, which would produce the same mistrial path as the noncharacter case. That is noted inside the text-rules finding rather than reported on its own.

mediumPush payments on the live IMD token (which has an owner block list): one blocked address locks a whole case and its potsrc/Briefs.sol:676
docs/audit-internal-2026-10.md accepts push payments on the premise that "Standard bridged IMD can't" blacklist. That premise does not hold for the token Briefs is deployed on. The live IMD token on Robinhood Chain (0x5F7Bb59365ce557C26dbcAa4EE9d39A4b95B7127) is a LayerZero OFT ("BridgedFP") with a public blocked(address) view, a transfersEnabled() switch and an owner (0x047F606fD5b2BaA5f5C6c4aB8958E45CB6B054B7, the same address that owns IMD's Intake).

On a fork of the live chain, setting blocked[x] (mapping at storage slot 13) makes transfer(x, 1) from the live Briefs revert with "BridgedFP: blocked", and clearing it makes the same transfer succeed.

Briefs pays by push inside the functions that advance the docket: the pot in _maybeSettle (line 676, reached from fulfill, mistrial, skipStalled and settle), the mistrial refund in mistrial (line 442) and the skip refund in _skip (line 596, reached from _hearNext and skipStalled).

If the standing leader is blocked while the final verdict is SUSTAINED (or a mistrial), every path that could close the case reverts and the pot (seed plus every entrant's 80% share) is locked for everyone, not only for the blocked address. If a challenger is blocked during their hearing, mistrial reverts and every brief behind them is queued forever.

If a queued author is blocked, the price-rise skip in _hearNext reverts, so even the verdict of the brief being heard cannot land. There is no admin rescue and no alternative path, and the blocking actor is a third party (a compliance action, not necessarily an attack). This merges the audit_permissions finding with the existing test_Known_L_Blacklisted* PoCs in test/audit/Liveness.t.sol, which show the same mechanism with a stand-in token.

Fix that keeps the design: credit the pot, the mistrial refund and the skip refund to a per-address claimable balance (or try the push and fall back to crediting on failure) so that no payment can stop the docket or settlement, and let the payee pull. The solvency invariant then counts the claimable balances.
Reproduced on this tree with test/scratch (the attached proof): a stand-in ERC20 whose _update reverts "BridgedFP: blocked" for a blocked from/to, deployed params (fee 5 IMD, seed 100 IMD, maxOracleFee 0.9, hearingGas 3M).

Scenario 1: creator opens case c; alice files a1 and is OVERRULED (leads); bob files b1; warp to endsAt; token owner blocks alice; call fulfill(b1, SUSTAINED attestation, sig).

Expected: b1 Sustained, case Settled, winner alice.

Actual: revert "BridgedFP: blocked" in _maybeSettle; mistrial(c) after the timeout also reverts; settle(c) reverts TooEarly; the pot of 100 + 3.6 IMD and bob's escrow stay locked.

Scenario 2: bob files b1 (hearing), alice files a1 (queued), bob is blocked, warp heardAt + 4 min + 2 min + 1 s, call mistrial(c).

lowIMD pricing the action above a case's fixed reserve refuses every new entry for the rest of the case, so the pot settles to whoever leads at that momentsrc/Briefs.sol:366
Each case fixes its jury reserve at creation (c.reserve = params.maxOracleFee, 0.9 IMD on the live deployment) and nothing can raise it or extend endsAt afterwards. The reserve protects escrowed fees (second review, fix 4), but it reintroduces the outcome the first internal review rated Medium (fix 1: "the owner could pause entries while a case's deadline kept running, locking in whoever led") with IMD's own price as the trigger instead of the owner.

The live Intake price is 0.5 IMD (priceOf read on chain). If IMD reprices the action above 0.9 IMD, then for every open case with nothing being heard fileBrief reverts OracleTooExpensive at this line, every brief already queued is handed back Unheard by the next hear()/skip, and when endsAt passes settle() pays 100% of the pot to the standing precedent.

The leader needs to do nothing and cannot be challenged; the creator, the owner (setParams reaches new cases only) and the players have no lever. On a 90-day case this freezes the contest for up to three months and then pays the leader.

Minimal fix that keeps the escrow guarantee: let anyone top up a case's jury budget from their own funds (never the pot) so hearings can pay the overshoot, or, while entries are refused for price, extend endsAt by the refused time so the contest resumes when the price falls. At minimum, document that a price rise above maxOracleFee ends the contest in the leader's favour.
Reproduced in test/scratch/IntakeProbe.t.sol test_IntakePriceLockIn (MockIntake + ImdGatewayRequester, deployed params) and test/scratch/Probe.t.sol test_PriceLockIn (MockRequester).

Steps: creator opens a 30-day case (seed 100 IMD, fee 2 IMD); alice files, IMD answers "better" through the Intake and fulfill lands it (alice leads); the Intake price becomes 1 IMD (> 0.9 reserve); bob calls fileBrief(c, ...).

Expected: bob's brief is queued or heard.

Actual: revert OracleTooExpensive (0x...), and the same for every address until endsAt; owner setParams(maxOracleFee 0.99) changes nothing for the running case.

At endsAt settle(c) pays alice the 100 IMD seed plus 1.2 IMD (80% of her own 2 - 0.5 fee), assertEq(winner, alice) passes.
lowA verdict IMD delivered on chain is voided by a mistrial if nobody relays it within DELIVERED_GRACE, because the jury keeps only its hashsrc/Briefs.sol:437
BriefsJury.onImdAnswer (src/BriefsJury.sol line 194) stores only keccak256(abi.encode(att)) and discards the attestation and signature the Intake delivered. Landing the verdict therefore needs an off-chain party to resubmit both through Briefs.fulfill within DELIVERED_GRACE (1 hour after the 4-minute answer window).

After that anyone can call mistrial and the delivered verdict is void for good: the precedent stands, the author gets fee minus the jury's price back, the pot gets nothing, and fulfill reverts WrongStatus forever. One side always prefers the mistrial: the leader when the answer was "better", the challenger when it was not (a mistrial refund beats losing the whole fee to the split).

The audit doc says a case finishes without the keeper, which is true, but the correct outcome does not: it depends on an interested party relaying within the hour. Storing the full attestation in the callback does not fit the Intake's 200,000 callbackGas (read on chain; about 15 extra slots would need about 300k).

Minimal fix: make the delivered grace a parameter sized for real keeper outages (attestations are valid for 86,400 s), and have the site offer the one-click relay to the winning side; or store the few signed fields the Intake delivers and let anyone fulfil with only the signature.
Reproduced in test/scratch/IntakeProbe.t.sol test_DeliveredVerdictLostToMistrial (MockIntake modelled on the live Intake's bytecode, ImdGatewayRequester).

State: creator opens a case; alice files brief id (hearing at heardAt); IMD's writer calls intake.complete(rid, 0, ..., abi.encode(rid, att{answer true, issuedAt heardAt + 100}, sig)) so jury.wasDelivered(id) == true.

Input: at heardAt + 4 min + 1 h + 1 s the creator (the leader) calls mistrial(c).

Expected: the answer IMD delivered on chain decides the hearing (alice becomes the precedent).

Actual: mistrial succeeds, brief status == Mistrial, precedent stays 1 (the opening brief), and fulfill(id, att, sig) reverts WrongStatus from then on.
lowBriefsText.check costs ~3.7k gas per ASCII character, so a max-length ASCII filing that opens a hearing needs ~5.6M gas, above the 4M the docs say the site sendssrc/BriefsText.sol:165
check() evaluates _forbidden(cp), _isSpace (twice) and _isFiller for every code point. _forbidden is a chain of about 95 comparisons with no early exit, and none of them can match a code point below 0x80, so every plain ASCII character pays for the whole chain. Measured on this tree: check() on 600 ASCII bytes costs 2,197,716 gas (about 3.66k per character) against 716,771 for 150 four-byte characters (600 bytes), and 1,833,016 for 500 ASCII bytes.

Briefs._hearNext then requires gasleft() >= hearingGas*64/63 + 60,000 (3,107,619 at the deployed hearingGas of 3,000,000) after the check, the brief storage and the request build, so a fileBrief that opens a hearing needs about 5,569,000 gas for a 500-byte ASCII brief (the deployed maxBrief) and about 4,335,000 for a 125-emoji brief. docs/audit-internal-2026-10.md (second review, fix 11) says the site and keeper send calls that may open a hearing with at least 4M gas; at that budget both filings revert OutOfGas() and the user pays for a failed transaction. openCase with all-max ASCII texts (48/240/160/500) costs 4,623,725 gas on its own.

No funds are at risk; this is a liveness/UX cost that is the dominant term of the gas a filer must bring and that a wallet estimate following the cheaper (stalled) path will miss.

Minimal fix: in _forbidden return false at once for cp < 0x80, and skip _isFiller/_isSpace for ASCII other than 0x20, which removes most of the per-character cost; then re-measure and raise the documented gas floor to what a max-length ASCII filing actually needs.
Reproduced in test/scratch/Probe.t.sol (test_CheckGas, test_FilingGasNeeded).

Deployed params (maxBrief 500, hearingGas 3,000,000), MockRequester at 0.5 IMD, a case open, nothing being heard.

Input: fileBrief(caseId, 500 x "a") from an approved account with exactly 4,000,000 gas (vm.cool on Briefs so storage is cold as in a real tx).

Expected (per the docs): the brief is filed and its hearing opens.

Actual: revert with selector 0x77ebef4d (Briefs.OutOfGas()) from _hearNext line 621.

Binary search over the gas limit: the call first opens the hearing at about 5,569,457 gas for the ASCII brief and about 4,335,448 for the 125 x U+1F409 brief.

Standalone: text.check(600 x "a", 1, 600, 600) consumes 2,197,716 gas; text.check(150 x U+1F409, 1, 600, 600) consumes 716,771.
lowThe answer window has no tolerance for clock skew: an attestation whose issuedAt is one second before its hearing's block timestamp can never landsrc/BriefsJury.sol:223
verdict() compares IMD's off-chain signing clock (att.issuedAt) with the chain's block timestamp at openHearing (b.heardAt) with a strict less-than and zero slack. On an L2 the sequencer sets block.timestamp from its own clock (Arbitrum-style chains allow it to run ahead of wall time); the attester sets issuedAt from its own.

If the sequencer's clock is ahead of IMD's by more than IMD's answer latency (43-63 s in the team's live probe), every answer for that hearing has issuedAt < heardAt and is refused for good, even though it was delivered by the Intake for this very requestId and carries this hearing's questionHash.

The hearing then ends only by mistrial: because wasDelivered() is true that waits heardAt + answerTimeout + DELIVERED_GRACE (64 minutes at the deployed 4-minute timeout), the challenger loses the jury's price and the standing leader keeps the lead on a brief IMD may have judged better.

The upper bound (issuedAt <= heardAt + answerTimeout) is a real liveness rule; the lower bound adds nothing on the production path, since the attestation must also be the one the Intake delivered for b.requestId, which cannot exist before the hearing opened.

Minimal fix: allow a small skew, e.g. require att.issuedAt + SKEW >= b.heardAt with SKEW around MISTRIAL_GRACE (2 minutes), or drop the lower bound for setups with an on-chain answer source.
Reproduced in test/scratch/Probe.t.sol test_ClockSkew.

Open a case, file a brief so its hearing opens at block timestamp T (b.heardAt == T).

Build a valid attestation for that hearing (its requestId, questionHashOf(briefId, 1, 2), panel 11/6/6, signed by the setup's attester for the jury's domain) with issuedAt = T - 1 and expiresAt = now + 1 day.

Call fulfill(briefId, att, sig) at T + 60.

Expected: the verdict lands (the answer is for this hearing's question and request).

Actual: revert BriefsJury.AnsweredBeforeAsked().

With issuedAt = T the same call succeeds and the brief is Overruled.
infoBriefsText._forbidden misses invisible format characters, more look-alikes of the «» quote marks, Unicode noncharacters and private-use code pointssrc/BriefsText.sol:166
Merged from audit_permissions (invisibles and look-alikes) and audit_flow (noncharacters and private use): the same function, the same kind of gap and one fix. check() documents that bidi and zero-width characters are refused and that text must reach IMD unchanged inside a JSON string; the internal reviews extended _forbidden three times on that basis (fixes 6, 7, 10 and swarm 5).

The list still admits: (a) Unicode Default_Ignorable format characters that renderers draw as nothing: U+206A..U+206F (deprecated format controls), U+1BCA0..U+1BCA3 (shorthand format controls), U+FFF0..U+FFF8, and the unassigned parts of the tag and variation-selector planes U+E0080..U+E00FF and U+E01F0..U+E0FFF (only U+E0000..E007F and U+E0100..E01EF are blocked); (b) look-alikes of the guillemets the question quotes with: U+2AF7/U+2AF8, U+2991/U+2992, U+2995/U+2996, U+FE3F/U+FE40, and doubled Canadian syllabics U+1438/U+1433, which the "<<" rule does not catch since it pairs only U+003C and U+003E; (c) noncharacters (U+FFFE, U+FFFF, U+FDD0..U+FDEF and U+nFFFE/U+nFFFF on every plane; "not intended for interchange", often replaced by U+FFFD or rejected by sanitizers) and the private-use areas (U+E000..U+F8FF, planes 15 and 16).

(a) and (b) are gaps against the stated rule with limited impact (the definitions tell the jury to ignore formatting tricks and the unassigned code points carry no readable text).

(c) matters if IMD's canonicaliser replaces or strips any of them: the questionHash rebuilt on chain uses the raw bytes, so the signed questionHash could never match, every hearing whose question contains that text would end in a mistrial and the standing precedent would keep the lead; the author of the opening brief controls text that appears in every question of the case.

Whether IMD alters these code points could not be verified offline, so (c) is reported as a text-rule gap, not a confirmed mistrial path.

Fix: add those ranges to _forbidden ((cp >= 0x206a && cp <= 0x206f), (cp >= 0x1bca0 && cp <= 0x1bca3), (cp >= 0xfff0 && cp <= 0xfff8), (cp >= 0xe0000 && cp <= 0xe0fff) as one range, (cp >= 0xfdd0 && cp <= 0xfdef), (cp & 0xfffe) == 0xfffe, optionally the PUA ranges) and treat U+1438/U+1433 like < and > in the doubling rule.
Reproduced in test/scratch/Probe.t.sol test_TextGaps.

Input: text.check(bytes.concat("a", utf8(cp), "b"), 1, 500, 500) for cp in U+206A, U+206F, U+1BCA0, U+1BCA3, U+FFF0, U+FFF8, U+E0080, U+E0FFF, U+2AF7, U+2AF8, U+2991, U+2992, U+2995, U+2996, U+1438, U+1433, U+FE3F, U+FE40, U+FFFF, U+FFFE, U+FDD0, U+FDEF, U+1FFFF, U+E000, U+F0000, U+10FFFF, and for "a" + U+1438 + U+1438 + "b".

Expected (by the rule the function documents and the treatment of U+200B, U+2060 and U+FEFF, which all revert BadText in the same run): revert BadText.

Actual: every one of them returns without reverting, so a brief or opening brief carrying them is filed and quoted verbatim in every hearing's question.
infoA case is pinned for up to 90 days to an Intake that may keep charging after IMD stops answering: each hearing then burns the challenger's jury price in a mistrial and the leader is locked insrc/Briefs.sol:441
Trust assumption on IMD's Intake, not stated in docs/audit-internal-2026-10.md. A case keeps its oracle setup for life (swarm fix 4) and the setup's requester pays IMD's Intake on every hearing.

If IMD retires or migrates the action (new Intake, writer stopped, action delisted off chain) while the old Intake still sells it on chain (priceOf > 0 and request() succeeding), hearings keep opening: each pays the price to the Intake, no callback arrives, and after answerTimeout + MISTRIAL_GRACE the brief is a mistrial refunded fee - price at this line. The skip path (whole fee back) is never reached because the requester never fails, so the stall clock never starts.

Every challenger loses 0.5 IMD per attempt, nobody can overrule the precedent, and at endsAt the pot goes to the leader. The jury owner can only add a new setup for new cases; running cases cannot be moved or paused.

Suggested bound that keeps the pot and escrow rules: let the jury owner mark a setup "retired" (a flag read in _hearNext that makes the hearing stall instead of paying, so briefs are skipped Unheard with their whole fee back and the case still settles), or stall automatically after N consecutive mistrials on one case.
Reproduced in test/scratch/IntakeProbe.t.sol test_SilentIntake (MockIntake whose writer never calls complete(), ImdGatewayRequester, deployed params). creator opens a 90-day case (fee 1 IMD, seed 100); alice files 20 briefs one after another; each opens a hearing that pays 0.5 IMD to the Intake, and after 6 minutes and 1 second anyone calls mistrial(c) (refund 0.5 IMD).

After 20 rounds the Intake's payee holds 10 IMD, alice is down 10 IMD, the precedent is still brief 1, and no address can change the case's setup.

Expected: a way to stop paying a jury that never answers, or a skip with the whole fee back.

Actual: at endsAt settle(c) pays the creator; assertEq(winner, creator) passes.
infoLive ownership of Briefs, BriefsJury and ImdGatewayRequester is a single EOA, not the multisig the audit doc relies onscript/Deploy.s.sol:97
Merged from audit_permissions and audit_economics (same fact, same fix). Admin powers and their bounds, as reviewed: Briefs owner: setParams (hard-bounded, new cases only), setPaused (new cases only), setHolderToken, openCase with minHold, setTreasury (instant; refuses Briefs, the jury and the current requester), proposeSink (at most 50% of the platform share, 2-day delay, applied by anyone, never reaches pots or escrow).

BriefsJury owner: proposeOracle (7-day delay, 7-day window; a setup decides verdicts only for cases whose creator names it; signer, requester and hearingGas are the owner's choice).

ImdGatewayRequester owner: setClient once, sweep of stray IMD to the Briefs treasury. None of these can take pots, escrowed fees or creator earnings, which matches the README. The swarm audit (finding 10) records "ownership of all three contracts goes to a multisig" as the mitigation for the jury owner choosing verdict setups.

The deploy script only starts that handover when NEW_OWNER is set, and on Robinhood Chain it was not: owner() of Briefs, BriefsJury and ImdGatewayRequester is the EOA 0x65751B8A6443BDDd8790D6f42547c0e7FA210620 (no code) and pendingOwner() is zero on all three (read 8 Oct 2026).

A leaked deployer key therefore gets: setTreasury to the attacker (every future caseFee and the whole platform share), proposeSink of 50% of the share to the attacker's contract after 2 days, and after 7 days in public a jury setup with the attacker's signer for any case whose creator then opens on it. Bounded (no access to pots or escrow), and a trust assumption rather than a code defect, but the documented mitigation is not in place.

Fix: run transferOwnership to the multisig on all three and acceptOwnership from it; until then the docs should state the actual owner.
On chain (chain id 4663, rpc.mainnet.chain.robinhood.com, 8 Oct 2026): cast call 0x85737d04bde718f42f90e31564540408cbbe6e4b "owner()(address)", cast call 0x265c541aa5c5f202e1e3024570cb7d8b278ca691 "owner()(address)" and cast call 0xbaee00b30d6f585218e257d84c70cf4181229592 "owner()(address)" all return 0x65751B8A6443BDDd8790D6f42547c0e7FA210620; "pendingOwner()(address)" returns the zero address on all three; cast code 0x65751B8A6443BDDd8790D6f42547c0e7FA210620 returns 0x.

Expected after the documented handover: a contract (Safe) address as owner of all three.
