+# .woodpecker/edge-subpath.yml — Edge subpath routing smoke test
+#
+# Runs end-to-end smoke tests for Forgejo, Woodpecker, and chat subpath routing:
+#   - Forgejo at /forge/
+#   - Woodpecker at /ci/
+#   - Chat at /chat/
+#   - Staging at /staging/
+#
+# Tests:
+#   1. Root / redirects to /forge/
+#   2. Forgejo login at /forge/ completes without redirect loops
+#   3. Forgejo OAuth callback for Woodpecker succeeds under subpath
+#   4. Woodpecker dashboard loads all assets at /ci/ (no 404s on JS/CSS)
+#   5. Chat OAuth login flow works at /chat/login
+#   6. Forward_auth on /chat/* rejects unauthenticated requests with 401
+#   7. Staging content loads at /staging/
+#
+# Triggers:
+#   - Pull requests that modify edge-related files
+#   - Manual trigger for on-demand testing
+#
+# Environment variables (set in CI or via pipeline):
+#   EDGE_BASE_URL        — Edge proxy URL (default: http://localhost)
+#   EDGE_TIMEOUT         — Request timeout in seconds (default: 30)
+#   EDGE_MAX_RETRIES     — Max retries per request (default: 3)
+#
+# When to run:
+#   - Any change to edge.hcl, docker/edge/, tools/edge-control/
+#   - Any change to this pipeline file
+#   - Manual trigger for testing edge deployments
