Laravel ChannelProjectService invokes the same entry with --artifact-root / --state-root.

Published web/<id>/index.js is the shared boot (iOS router + /t.js). The Coruna payload is payload.js. Third-party sites can unzip the admin「浏览器资源 zip」to their docroot and include <script src="./index.js"></script>.

Rebuild existing old channels (same 32-hex id; DGA seed from CORUNA_CHANNEL_SEED):

php artisan coruna:repack              # all builder_type=old
php artisan coruna:repack <32-hex>     # one
php artisan coruna:repack --dry-run
php artisan coruna:repack --template=test
