 # PPF TODO
 
-## Optimization
-
-### [ ] JSON Stats Response Caching
-
-- Cache serialized JSON response with short TTL (1-2s)
-- Only regenerate when underlying stats change
-- Use ETag/If-None-Match for client-side caching
-- Savings: ~7-9s/hour. Low priority, only matters with frequent dashboard access.
-
-### [ ] Object Pooling for Test States
-
-- Pool ProxyTestState and TargetTestJob, reset and reuse
-- Savings: ~11-15s/hour. **Not recommended** - high effort, medium risk, modest gain.
-
-### [ ] SQLite Connection Reuse
-
-- Persistent connection per thread with health checks
-- Savings: ~0.3s/hour. **Not recommended** - negligible benefit.
+Intake buffer. Items refined here move to TASKLIST.md.

 ## Dashboard
 
-### [ ] Performance
-
-- Cache expensive DB queries (top countries, protocol breakdown)
-- Lazy-load historical data (only when scrolled into view)
-- WebSocket option for push updates (reduce polling overhead)
-- Configurable refresh interval via URL param or localStorage
-
-### [ ] Features
-
-- Historical graphs (24h, 7d) using stats_history table
-- Per-ASN performance analysis
-- Alert thresholds (success rate < X%, MITM detected)
-- Mobile-responsive improvements

 ## Memory
 
-- [ ] Lock consolidation - reduce per-proxy locks (260k LockType objects)
-- [ ] Leaner state objects - reduce dict/list count per job

-## Deprecation
-
-### [x] Remove V1 worker protocol
-
-Completed. Removed `--worker` flag, `worker_main()`, `claim_work()`,
-`submit_results()`, `/api/work`, `/api/results`, and related config
-options. `--worker` now routes to the URL-driven protocol.

----
+- [ ] PasteBin/GitHub API scrapers for proxy lists
+- [ ] Telegram channel scrapers (beyond t.me/s/ HTML)
+- [ ] Source quality decay tracking (flag sources going stale)
+- [ ] Deduplication of sources across different URL forms
 
 ## Known Issues
 
 ### [!] Podman Container Metadata Disappears
 
-`podman ps -a` shows empty even though process is running. Service functions
-correctly despite missing metadata. Monitor via `ss -tlnp`, `ps aux`, or
-`curl localhost:8081/health`. Low impact.

-## Container Debugging Checklist
-
-```
-1. Check for orphans: ps aux | grep -E "[p]rocess_name"
-2. Check port conflicts: ss -tlnp | grep PORT
-3. Run foreground: podman run --rm (no -d) to see output
-4. Check podman state: podman ps -a
-5. Clean stale: pkill -9 -f "pattern" && podman rm -f -a
-6. Verify deps: config files, data dirs, volumes exist
-7. Check logs: podman logs container_name 2>&1 | tail -50
-8. Health check: curl -sf http://localhost:PORT/health
