## What To Do
1. Read the failing source files to understand the current code
2. Identify what's causing each test failure
3. Fix the code by editing the files
4. Do NOT add comments to the code
5. Do NOT refactor or change anything beyond what's needed to fix the failures
6. Do NOT create new files unless absolutely necessary
7. Do NOT run git commands

## Important Context
- The app is Astro 5.7 with Preact, running on port 6572 at localhost
- palacecode is at /code/, palacemail is at /mail
- API endpoints are under /code/api/ (palacecode) and /api/mail/ (palacemail)
- After you fix the code, the build system will rebuild and restart automatically
- palacecode uses Redis (ioredis) on port 6399 for thread storage
- palacemail uses ImapFlow for IMAP and Nodemailer for SMTP to Purelymail

Fix every failure. Be precise. Be minimal.
