Subject: [PATCH] fix: Stop Drift verifier retry loop cancelling orders (Bug
 #80)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CRITICAL FIX (Dec 9, 2025): Drift state verifier now stops retry loop when close transaction confirms, preventing infinite retries that cancel orders.

Problem:
- Drift state verifier detected 'closed' positions still open on Drift
- Sent close transaction which CONFIRMED on-chain
- But Drift API still showed position (5-minute propagation delay)
- Verifier thought close failed, retried immediately
- Infinite loop: close → confirm → Drift still shows position → retry
- Eventually Position Manager gave up, cancelled ALL orders
- User's position left completely unprotected

Root Cause (Bug #80):
- Solana transaction confirms in ~400ms on-chain
- Drift.getPosition() caches state, takes 5+ minutes to update
- Verifier didn't account for propagation delay
- Kept retrying every 10 minutes because Drift API lagged behind
- Each retry attempt potentially cancelled orders as side effect

Solution:
- Check configSnapshot.retryCloseTime before retrying
- If last retry was <5 minutes ago, SKIP (wait for Drift to catch up)
- Log: 'Skipping retry - last attempt Xs ago (Drift propagation delay)'
- Prevents retry loop while Drift state propagates
- After 5 minutes, can retry if position truly stuck

Impact:
- Orders no longer disappear repeatedly due to retry loop
- Position stays protected with TP1/TP2/SL between retries
- User doesn't need to manually replace orders every 3 minutes
- System respects Drift API propagation delay

Testing:
- Deployed fix, orders placed successfully
- Database synced: tp1OrderTx and tp2OrderTx populated
- Monitoring logs for 'Skipping retry' messages on next verifier run
- Position tracking: 1 active trade, monitoring active

Note: This fixes the symptom (retry loop). Root cause is Drift SDK caching getPosition() results. Real fix would be to query on-chain state directly or increase cache TTL.
