Common work-related issues:
| Symptom | Likely Cause | Fix | |---------|--------------|-----| | “Hash mismatch” during software install | Corrupted download | Re-download file and recompute hash | | “Duplicate key” in DB | Hash used as unique constraint | Check for collision (rare but possible) | | “Invalid request token” | Session hash expired or malformed | Regenerate token | | “File not found: …/hash” | Content-addressed storage missing blob | Restore from backup or rebuild cache | Crucially, hashing is not encryption
