Done. Here’s a complete summary of what was accomplished:

CI4 Migration — What Was Fixed Tonight

✅ Composer & Dependencies

• composer install --no-dev — all SDKs now installed (qiniu/php-sdk, predis/predis, pingpp-php, phpspreadsheet, php-amqplib, pili-engineering-sdk)
• php-ffmpeg excluded (requires ext-gd not available; CI4 framework restored after accidental removal)

✅ Payment Stubs (Critical)

• app/Libraries/WxPay.php — JSAPI/app/QR code charge stubs, refund/transfer/redpack stubs
• app/Libraries/WxPayCallback.php — WeChat pay callback handler (stub, safe to receive real notifs)
• app/Libraries/Alipay.php — Alipay charge stub

✅ CI3 Compatibility Layer

• app/Config/CI3Compat.php — provides get_instance(), CI3_Loader_Proxy, and CI3_Loader for CI3-era library code (Pay, WeChatAppClient, etc.)
• app/Config/NamespaceBridge.php — maps App\Libraries\* → App\Models\* for DAO cross-namespace access

✅ Broken Files Fixed

• Constants.php — repaired 8+ broken define() calls (truncated heredocs, duplicate env constants with bad if-else)
• Wechat.php — duplicate callback() method split into callback (GET) / callbackPost (POST)
• Accounts.php — stray public public PHP 8 syntax error removed
• Lives.php — added use statements for WeChatAppClient, QiniuLive
• JobHelperDao.php — added use App\Controllers\WeChatAppClient
• Pay.php / PayNotifyDao.php — fully qualified class refs for models
• WeChatAppClient.php — rewired to namespace App\Controllers + global alias
• wxencrypt/* — namespace wrappers, mcrypt→OpenSSL replacement

✅ CI4 DB API Migration

• Bulk replaced ->result() → ->getResult(), ->row() → ->getRow() across all model files

✅ PSR-4 & Classmap Fixes

• App\Libraries added as PSR-4 namespace
• All model files given class_alias for cross-namespace resolution

✅ Archived Old Code

• application/ → application_ci3/ (all CI3 code safely archived)

✅ Pushed to GitHub

Current Route Status

Route	Status	Note
/	✅ 200
/users/isRegister	✅ 200
/lives/count	✅ 200
/lives/recommend	✅ 200
/wechat/sign	✅ 200
/topics	✅ 200
/applications/me	✅ 200
/accounts/me	✅ 200
/wechat/menu	⚠️ 500	Redis not running in container
/jobs/alive	⚠️ 500	Redis not running in container

Remaining (Not in This Session)

• Redis — needs to be started (live-server-redis-1) for /wechat/menu and /jobs/alive
• Session/auth flow — real login round-trip testing
• Database migrations — CI4 migrations vs existing CI3 schema
• POST /charges, POST /rewards — routes exist but payment logic uses stubs
