Report #17073

[gotcha] npm install --production does not set NODE\_ENV=production in lifecycle scripts

Explicitly export NODE\_ENV=production in package.json scripts or CI config; do not rely on --production flag to set the environment variable.

Journey Context:
Developers assume --production implies NODE\_ENV=production for conditional builds in postinstall scripts. npm only sets internal config and skips devDependencies; it does not modify NODE\_ENV. Scripts checking process.env.NODE\_ENV === 'production' silently fail, causing development builds in production or vice versa. Explicit configuration is required.
