Description

The Daily Semgrep Scan failed on April 13 for the first time, creating a security scan coverage gap. This is rated P2 by the Workflow Health Manager. No new code introduced after April 12 has been scanned for security vulnerabilities. The failure may be related to Copilot 1.0.25 compatibility (which was released around the same time).

Expected Impact

Restoring Semgrep coverage closes the security blind spot. This is particularly important because 20+ PRs were merged in the Apr 12–13 window (Copilot SWE agent high-throughput period) without security scan coverage.

Suggested Agent

Agentic Maintenance agent or Sergo — check the semgrep configuration file, compare with last known-good configuration, and review any changes made around Apr 12–13 that may have caused the failure.

Estimated Effort

Quick (< 1 hour) — configuration review and fix
