-## Outstanding Issues
-
-### 1. Ctrl+C Signal Handling Issue
-
-**Problem**: The crawler sometimes doesn't exit properly when Ctrl+C is pressed.
-
-**Root Cause**: The main thread gets stuck in blocking operations before it can check for signals:
-- Database operations in the polling loop (`cmd/crawler/crawler.go:239-250`)
-- Job queueing when channel is full (`jobs <- url` can block if workers are slow)
-- Long-running database transactions
-
-**Location**: `cmd/crawler/crawler.go` - main polling loop starting at line 233
-
-**Solution**: Add signal/context checking to blocking operations:
-- Use cancellable context instead of `context.Background()` for database operations
-- Make job queueing non-blocking or context-aware
-- Add timeout/cancellation to database operations
-
-### 2. fetchSnapshotsFromHistory() Doesn't Work with --skip-identical-content=true
-
-**Problem**: When `--skip-identical-content=true` (default), URLs with unchanged content get continuously re-queued.
-
-**Root Cause**: The function tracks when content last changed, not when URLs were last crawled:
-- Identical content → no new snapshot created
-- Query finds old snapshot timestamp → re-queues URL
-- Creates infinite loop of re-crawling unchanged content
-
-**Location**: `cmd/crawler/crawler.go:388-470` - `fetchSnapshotsFromHistory()` function
-
-**Solution Options**:
-1. Add `last_crawled` timestamp to URLs table
-2. Create separate `crawl_attempts` table  
-3. Always create snapshot entries (even for duplicates) but mark them as such
-4. Modify logic to work with existing schema constraints
-
-**Current Status**: Function assumes `SkipIdenticalContent=false` per original comment at line 391.
