+# Cleanup: Duplicate Labels and PRs from Issue-Poller Loop
+
+## Project
+paper-dynasty-database on git.manticorum.com
+
+## What Was Cleaned Up
+
+### Duplicate PRs
+Closed PRs #36, #37, #39 (created by the infinite loop). Left open:
+- PR #35 — real fix for issue #25
+- PR #38 — fix for issue #24
+
+### Duplicate Repo Labels
+Deleted 8 duplicate labels:
+- 4 extra `ai-working` labels (IDs 49, 41, 56, 58)
+- 4 extra `ai-reviewing` labels (IDs 51, 59, 57, 50)
+
+These were created because Haiku kept calling `create_repo_label` instead of checking for existing labels first.
+
+## Root Cause of Duplicates
+The Haiku-based label creation did not search existing labels before creating. Each poll cycle created new label entries.
+
+## Prevention
+The `ensure_label()` helper function in the rewritten poller searches existing labels first and only creates if missing:
+
+```bash
+ensure_label() {
+  local name="$1"
+  local color="$2"
+  # Search existing labels, create only if not found
+  existing=$(gitea_get "/repos/$OWNER/$REPO/labels" | jq -r ".[] | select(.name==\"$name\") | .id")
+  if [ -z "$existing" ]; then
+    gitea_post "/repos/$OWNER/$REPO/labels" "{\"name\":\"$name\",\"color\":\"$color\"}"
+  fi
+}
+```
