Implements process-level environment variable protection per the spec. When the sandbox is enabled, credential-bearing variables are removed from the package manager child process before it is spawned, defending against supply chain attacks that harvest secrets from the environment. - DANGEROUS_ENV_VARS: curated default deny list of known secret names (no generic *_TOKEN/*_SECRET catch-alls); ScrubEnv matcher supports case- insensitive globs so profiles can opt into broader denies. - EnvironmentPolicy (environment.allow / environment.deny) on sandbox profiles, merged under inheritance; deep-copied on resolve. - npm/pypi profiles re-allow their own ecosystem's auth vars so package managers keep working; other ecosystems' and cloud creds stay scrubbed. - New 'env' --sandbox-allow type (and overlay support via the same path): allow-only, value kept verbatim (not path-resolved), governed by lockdown. - Enforced in executor.ApplySandbox as the last step before launch, after overlay and runtime overrides merge; scrubbed names logged for audit. https://claude.ai/code/session_017Da1sAYLYpeEgogm6f9VYW
