-(running independently; will log findings here)
+### BP-mirror-1: Bridge auth (non-org-member rejection)
+`GET /orgs/recipe-maintainers/members/nonexistentuser12345` → 404 ✓ (correctly rejected)
+Auth enforcement confirmed working at this snapshot.
+
+### BP-mirror-2: Bridge current POLL_REPOS (live vs config)
+Live bridge task `9mtdhzx7eylfleg6qd94tseua` started with correct POLL_REPOS including:
+custom-html-tiny, lasuite-meet, uptime-kuma — all additions from Phases 3/5 ✓
+
+Note: `docker service inspect` showed TWO POLL_REPOS env var entries in service JSON.
+The LAST one (uptime-kuma included) is the current spec; the earlier was from a pre-update
+spec snapshot. Running container correctly uses the full list (confirmed via service log).
+
+### BP-mirror-3: Box cleanliness
+`docker stack ls` on cc-ci shows exactly 5 legitimate stacks:
+backups, ccci-bridge, ccci-dashboard, drone, traefik. No orphaned test app stacks ✓
+Disk: 35G used / 150G total (25%) — healthy headroom for mirror creation work ✓
+
+### BP-mirror-4: hedgedoc PR #1 open (pre-existing probe PR)
+`recipe-maintainers/hedgedoc/pulls/1` is still open — it's the Phase 1d DG6 generic suite
+probe (`ci/testme-probe` branch). This PR predates the mirror phase. When the Builder
+authors the hedgedoc test suite (Phase 2), this open PR is a natural place to run !testme.
+**No action needed now**; noted as context for Phase 2 verification.
+
+### BP-mirror-5: Upstream recipe availability for 3 missing mirrors
+- `git.coopcloud.tech/coop-cloud/lasuite-drive` → 200 ✓
+- `git.coopcloud.tech/coop-cloud/mailu` → 200 ✓
+- `git.coopcloud.tech/coop-cloud/mumble` → 200 ✓
+All three exist upstream; mirror creation (Phase 1) should proceed without obstruction.
