Replace the opt-in sweep-targets allowlist with zero-wiring discovery: enumerate org
repos via the GitHub REST API (curl + read-only GH_TOKEN, no gh dependency) and mirror
each as a shallow clean clone (git clone --depth=1, default branch from the API) into
~/repo-mirrors. Scanning server-side clones keeps local .env secrets out of scope.
Tier 1 runs deterministic scanners over every repo nightly ($0 Claude); tier 2 runs the
agentic pass over a budget-bounded round-robin rotation with a persistent cycle pointer,
so the draw on the shared Max limits stays bounded and coverage never goes silently
incomplete (COVERAGE ALARM if the rotation falls behind). Skip = committed marker or
central list (marker-skips logged). Redact secrets from Slack; reports mode 600. Raise
the systemd timeout to 6h for the longer two-tier run.
