## What changed
- Add `NODE_REPL_AUTH_TOKEN` to the environment variables that model-reachable child processes cannot inherit.
- Remove the variable case-insensitively after shell environment policy overrides and from explicitly configured child command environments.
- Extend the environment scrubber tests to cover inherited and configured forms of the token.

## Why
`CODEX_EXEC_SERVER_NOISE_AUTH_TOKEN` is an execution-server credential and
must not be exposed to model-reachable commands or command hooks, including
when shell environment policy explicitly sets a case variant of the name.
## What changed
- Add `CODEX_EXEC_SERVER_NOISE_AUTH_TOKEN` to the shared list of
non-inheritable environment variables.
- Keep the environment variable constant in `codex-protocol` so the exec
server and environment scrubber use the same definition.
- Verify case-insensitive removal after policy overrides for shell commands
and command hooks.

## What changed
- Read optional workload identity context from `OPENAI_WORKLOAD_IDENTITY_CONTEXT` and forward it unchanged as the `workload_identity_context` token exchange field.
- Treat the context as sensitive by redacting it from session configuration debug output and removing it from model-reachable child environments.
- Include the context in workload identity session fingerprints so sessions with different values cannot share an exchange.
## Testing
- Cover request forwarding, debug redaction, session compatibility, and child-environment scrubbing.

## Why
Model-reachable child processes should not inherit Codex launch context.
## What changed
- Treat `OPENAI_FEDERATION_RULE_ID` and `OPENAI_IDENTITY_TOKEN_FILE` as non-inheritable environment variables, with case-insensitive matching.
- Remove them after shell environment policy overrides and before spawning commands across execution, MCP, hooks, Git helpers, and remote helper processes.
## Testing
- Cover inherited and explicitly configured variants, including mixed-case names.
- Verify the variables are absent from real child environments and app-server command and process execution.
