Audit: Arkadiko Freddie v1-1 (arkadiko-freddie-v1-1) — static-analysis (5,000 sats)

Top 3 findings:

1. F-01 (medium): close-vault missing vault owner authorization — no (asserts! (is-eq tx-sender (get owner vault))) guard. Any caller can force-close any vault, triggering DAO-authorized burn of the owner's USDA without in-tx consent and returning collateral to owner. No direct fund theft, but a real griefing vector against active leveraged positions. Fix: add tx-sender == owner assert as the first check.

2. F-03 (low): Pervasive unwrap-panic on DAO contract lookups (get-emergency-shutdown-activated, get-qualified-name-by-name, etc.) in every user-facing function. If any DAO call reverts (upgrade, misconfiguration), vault operations panic with no informative error code. Fix: replace with unwrap! + defined error constants.

3. F-04 (low): redeem-tokens has no caller authorization. Anyone can trigger USDA/DIKO distribution to DAO payout address once the 31-day time gate clears. Caller-supplied amounts are not validated against actual balance. Funds flow to DAO not attacker, but permissionless triggering drains accumulated stability fees before governance review. Fix: add governance caller check or cap amounts to actual balance.

No high or critical findings. The contract is a thin orchestration layer over arkadiko-vault-data-v1-1 with proper shutdown and stacking-in-progress guards.

Top 3 findings:

1. [Medium / F-01] burn lacks a vault-owner authorization check — any caller can invoke burn(vault-id, debt) on any vault, burning their own USDA to reduce someone else's debt and paying that vault's stability fees. All other vault-mutation functions enforce tx-sender == vault.owner; this is the only exception, creating inconsistent access control.
2. [Medium / F-02] release-stacked-stx has no caller authorization despite its comment stating "can only be called by deployer" — any principal can trigger the post-unlock STX release for any liquidated xSTX vault once the burn height is reached, removing sequencing control from the protocol.
3. [Medium / F-03] redeem-tokens has no authorization beyond a 31-day block-height gate — any principal can call it with arbitrary amounts (including 0/0), which in the 0-amount case updates block-height-last-paid without transferring funds, locking out legitimate foundation payouts for 31 days.

No High or Critical findings. No private disclosure required.
