# Basket Mint Re-audit Report

**Revision reviewed:** updated `basket-mint-contracts-audit.zip` supplied for remediation review.

## Result

All four findings from the previous review are remediated in the reviewed revision. I found no new high-, medium-, or low-severity issue in the changed code paths.

| Prior ID | Result | Evidence |
| --- | --- | --- |
| H-01: stale collateral feed | Resolved | `collateralPrice()` now validates a nonzero heartbeat, positive/complete/nonfuture answer, completed round, and staleness. Factory validation prevents configuring a feed without a heartbeat. |
| M-01: non-$1 collateral conversions | Resolved | `_usdToCollateral()` correctly inverts the collateral valuation formula with upward rounding, and is used for mint fees, stability fees, liquidation seizure, and principal calculation. |
| M-02: zero-staker reward loss | Resolved | Last-staker withdrawal checkpoints earned rewards, freezes the stream, records the unvested amount in `undistributed`, and either rolls it into a later stream or allows owner recovery. |
| L-01: overnight weekday handling | Resolved | The morning portion of an overnight window checks the previous day; the evening portion checks the current day. |

## Verification

The updated source compiled with solc 0.8.24 and the full Foundry suite passed:

- **40 passed, 0 failed, 0 skipped** across five suites.
- Includes the two stateful solvency invariants (64 runs and 2,048 calls each).
- Includes new regression coverage for stale/future collateral data, non-$1 mint-fee scaling, last-staker reward handling, and overnight boundaries.

## Residual deployment assumptions

- The configured collateral must be a standard, non-fee-on-transfer ERC-20; the market accounts for the requested transfer amount rather than measuring the actual balance received.
- Oracle feed selection, heartbeat sizing, owner/guardian control, insurance funding, and governance recovery authority remain deliberate operational trust assumptions.
- This review validates the remediation diff and the supplied tests; it is not a formal assurance or launch approval.
