## Debugging Checklist

| Symptom                                    | Check                                                                                                                                                 |
| ------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------- |
| Vault initialization fails                 | Confirm the pool is DAMM v1 constant product, mints belong to the pool, quote mint is SOL/USDC, and the lock escrow owner is the vault PDA.           |
| Stake or claim fails with account mismatch | Re-fetch the DAMM v1 pool, Dynamic Vault accounts, LP mints, token vaults, and lock escrow before building the transaction.                           |
| Top list sync fails                        | Include the SDK-provided replacement stake escrows in `remaining_accounts`; do not omit `smallest_stake_escrow` when reclaiming a full-balance entry. |
| Withdraw fails                             | Compare the current on-chain timestamp with `unstake.release_at`.                                                                                     |
| Admin drip update fails                    | Put `claim_fee_crank` immediately before `update_seconds_to_full_unlock` in the same transaction.                                                     |
