Fixed! 🦞 Here’s what I did in this session:

What was fixed

🔴 P0 — Database connection

• app/Config/Database.php — was hardcoded with hostname: 'localhost'. The env vars (DB_HOST=database) were injected into the container but never read by CI4’s $default config. Fixed with getenv() calls in the constructor. Result: DB now connects.

🔴 P0 — Missing JSSDK library

• app/Libraries/JSSDK.php — created from scratch (CI4, no get_instance(), proper DI via WxDao and WeChatClient)
• app/Libraries/WeChatPlatform.php — created (all notification/template message methods)
• app/Models/UserDao.php — added use App\Libraries\JSSDK; to fix PHP namespace resolution (inside App\Models, new JSSDK() was resolving as App\Models\JSSDK, not global JSSDK)

🟡 P1 — Missing Pay, Sms, LeanCloud libraries

• app/Libraries/Pay.php — created (payment processing for Alipay/WeChat)
• app/Libraries/Sms.php — created (LeanCloud SMS notifications)
• app/Libraries/LeanCloud.php — created (CI4-compatible HTTP client)
• app/Config/Autoload.php — added classmap entries for all CI3-style class names

✅ Result: curl localhost:8088/ → HTTP 200

What’s still outstanding (not blocking, but needed)

Item	Priority	Notes
WxPay, Alipay, WxPayCallback stubs	🟡 P1	Used by Wechat, Charges, Rewards controllers — will 500 if those endpoints hit
$this->load->library() / $this->load->model() in all 20 controllers	🟡 P1	Still CI3-style, need DI or Services:: refactor
Routes	🟡 P1	Only / defined — all other CI3 routes need CI4 $routes-> entries
REST_Controller removal	🟢 P2	API controllers may still extend it — need to check

Want me to continue with the P1 items, or are you good for now?
