Context: Bug report "Users can't log in"
## Bug Analysis
**Symptoms**:
- Users see "Invalid credentials" error
- Occurs only for accounts created after Oct 15
- Works fine for older accounts
**Reproduction Steps**:
1. Create new user account
2. Log out
3. Attempt to log in with correct credentials
4. Observe error message
**Root Cause**:
- Code inspection of auth system
- Found: Password hashing algorithm changed Oct 15
- Old accounts use bcrypt, new accounts use argon2
- Login validation only checks bcrypt
**Location**: `src/auth/validator.py:45-67`
**Impact**:
- Severity: Critical (blocks all new users)
- Affected: ~500 accounts created in last week
- Workaround: None available
**Fix Strategy**:
- Update validator to check both hash types
- Add migration for existing argon2 hashes
- Estimated effort: 2 hours (small fix)
- Testing required: Auth system regression tests
**Priority**: Critical - Fix immediately
**Recommended Agent**: implementer (straightforward code fix)
