…of-band When Creator and the cli-driven IDE open the same project, they share <project>/temp/programming/packer-driver. Creator recompiling on save mutates that shared store (new chunk hashes, old chunks removed); the cli then serves a stale in-memory import-map / browser-cached chunk that references a removed chunk hash, so the preview fails with SystemJS Error#3 (chunk 404). - scripting-routes: serve pack resources (/scripting/x, /chunks) with Cache-Control: no-store so the browser never keeps a stale chunk / import-map. - live-reload: watch temp/programming/packer-driver; when import-map / resolution-detail-map change (a compile finished, possibly in another process), refresh the in-memory QuickPackLoader (facet.notifyPackDriverUpdated) and trigger a browser reload, so the preview loads a consistent import-map + chunks.

Problem
When Cocos Creator and the cli-driven IDE open the same project at the same time, both share
<project>/temp/programming/packer-driver. Editing and saving a script that the scene references makes Creator recompile out-of-band, mutating that shared pack store (new chunk hashes, old chunks removed). Opening/refreshing the cli preview then fails with high probability:i.e. a loaded chunk imports a chunk hash that no longer exists (404). Two causes:
QuickPackLoaderstill holds the previous import-map (it doesn't know another process recompiled), andChanges
/scripting/x,/chunks) withCache-Control: no-store, so the browser never keeps a stale chunk or import-map.temp/programming/packer-driver; whenimport-map.json/resolution-detail-map.jsonchange (a compile finished — possibly in another process such as Creator), refresh the in-memory loader viafacet.notifyPackDriverUpdated()and trigger a browser reload, so the preview always loads a consistent import-map + chunks.Notes
temp/packer-driver(does not isolate cli's output); the fix makes the cli reactive to external recompiles instead.recursive(supported on Windows/macOS; degrades gracefully on Linux where the config/compiledevents still cover in-process changes).maincurrently failstsc -bdue to a missing export unrelated to this change); these two files are type-clean. Merge fix(preview): add missing fillIncludeModulesFromProjectConfig; add tsc type-check to PR CI #724 first, or together.Test
