Review complete. The findings file is written and valid, no source file was changed, and the working tree has no stray files.

Outcome. The code as it stands shows no loss-of-funds or access-control defect that I could reproduce. I recorded one low finding and one info finding in .imd-findings.json. Neither is critical or high, so no proof file is attached. This is a review of what I could reach in the time budget, not a statement that the code is audited or secure.

Manifest. launch.json is valid for the factory: only schema keys, strings for addresses and notes, numbers for fee, tick spacing and decimals, lowercase paired currency, constructor arguments in the declared order with no literal addresses, and six permissions that encode to 10444 and match the hook's own permission function. The token name is nine characters, the symbol SVO, decimals 18. Notes are 3,864 characters. The indicative price is below 2^160.

Mining. PrepareLaunch found a salt for the local fixture and the hook deployed at an address carrying flags 10444, built its vault, accepted initialization from the factory at the manifest's fee and tick spacing, and refused a 3000 fee tier. The real salt must be mined again with the chain's manager, token and factory addresses.

Findings.

• Low, src/SovrnHook.sol:126. The opening-hour liquidity lock exempts every sender while the timestamp equals the opening timestamp. On a sub-second chain several blocks share one timestamp, so a non-factory LP in a following block placed an IMD-only range and was filled by sell flow fee-free. Measured: 3.75 IMD bought about 4.1M SVO, the vault earned 0.16 IMD from the seller's fee, and a direct buy of the same IMD paid 1.87 IMD. This is the parked route from launch #1173 narrowed to one second rather than closed.
• Info, test/LiquidityLock.t.sol:23. The regression test's "IMD-only range" lies on the wrong side of the fixture price and holds SVO only in both currency orders, so the suite never exercises the route it names.

Trust assumptions, not defects. The IMD owner's transfer gate or blocklist can halt every fee-bearing swap and strand claims until lifted. The PoolManager owner can set a protocol fee. A router that syncs IMD before the swap must add the hook fee to its payment or its settlement reverts. All three are already in the manifest notes.

Coverage. I read all five contracts in src/, the preparation script, the shared test fixture, the router mock and the lock tests, and traced the four swap modes, the quote path, claim fallback and vault accounting against the Pashov and v4 checklists. Not reached: the real IMD token's behaviour on chain 4663 (fork test unrun), the launch factory's seeding path, and whether the Safe or vault can be blocklisted by IMD's owner.
