Custom Environment Variables Warning

Entry

Bug FixesSection of the release
What

Infrastructure added to detect and warn about custom environment variables in project/local settings.

Status

Code exists but appears to be internal validation only.

Details
  • Maintains an allowlist (i9A) of known/safe environment variable names
  • Can detect when project settings contain non-allowlisted env vars
  • Function iC9() returns list of settings files with custom env vars
Evidence

uC9() at line 530822 (env validator, checks against i9A allowlist)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
