Pre-filter upstream-blocked container/image CVE findings before assigning to the Copilot coding agent
Description: The 7-day Prompt Clustering Analysis (discussion #53637) found that "Container/Image Security Pinning" tasks (Cluster 4, 88 PRs, 9% of all Copilot-agent PRs) merge at only 53.4%, 23.4 points below the 76.8% overall rate — the only cluster clearing the outlier threshold. Root-cause analysis of all 41 closed (unmerged) PRs in this cluster found 80% (33/41) reflect a scope problem: 68% are abandoned [WIP] drafts (vs. only 1/47 merged PRs staying [WIP]), and 12% are explicitly "fix belongs upstream in gh-aw-firewall / a third-party MCP image" tracking PRs that were never actionable in this repo to begin with. These are automated daily CVE/license-scan findings opened as PRs regardless of whether the finding is fixable locally.
Expected Impact: A lightweight triage step (check whether the vulnerable component is vendored in-repo vs. an upstream dependency before assigning) would eliminate the ~12% "upstream-blocked" bucket outright; adding a stale-[WIP] reaper (auto-close/nudge after N days of no follow-up commits) would surface the other 68% faster instead of leaving them open indefinitely. Together these could bring Cluster 4's merge rate much closer to the 76.8% fleet average and stop burning agent cycles on unfixable-in-repo findings.
Suggested Agent: New Agent (workflow-config change to whichever workflow opens the container/CVE-scan PRs, e.g. the daily grype/grant CVE remediation workflow).
Estimated Effort: Medium (1-4 hours) — add an upstream-vs-vendored check and a stale-WIP auto-close/nudge policy.
