Critical Hotfix: Database Migration Issue (#121)

This is an emergency hotfix addressing a critical database migration bug that prevented claude-mem from loading for some users.

What was fixed

Issue: Users were seeing SqliteError: no such column: discovery_tokens when starting Claude Code.

Root Cause: The ensureDiscoveryTokensColumn migration was using version number 7, which was already taken by another migration (removeSessionSummariesUniqueConstraint). This duplicate version number caused migration tracking issues in databases that were upgraded through multiple versions.

Fix:

• Changed migration version from 7 to 11 (next available)
• Added explicit schema_versions check to prevent unnecessary re-runs
• Improved error propagation and documentation

Upgrade Instructions

If you're experiencing the error:

Option 1 - Manual fix (preserves history):

sqlite3 ~/.claude-mem/claude-mem.db "ALTER TABLE observations ADD COLUMN discovery_tokens INTEGER DEFAULT 0; ALTER TABLE session_summaries ADD COLUMN discovery_tokens INTEGER DEFAULT 0;"

Option 2 - Delete and recreate (loses history):

rm ~/.claude-mem/claude-mem.db
# Restart Claude Code - database will recreate with correct schema

Option 3 - Fresh install:
Just upgrade to v6.0.7 and the migration will work correctly.

Changes

• Fixed: Database migration version conflict (migration 7 → 11) (#121)
• Improved: Migration error handling and schema_versions tracking
