+# #9310 §3.16: the packages/ui fixture e2e runners (src/**/__e2e__/run-*.mjs)
+# esbuild-bundle REAL shipped components into a self-contained page and drive
+# them with real input in headless Chromium — no app server, no credentials,
+# fully deterministic. All were verified to run locally, but only the chat
+# gesture trio (ui-e2e-gate.yml), the swipe/perf set (chat-shell-gestures.yml),
+# and tutorial/perf-gate (test.yml) had CI legs; the ten runners below were
+# wired to NO workflow, so a regression in the agent-surface bridge, bottombar,
+# ambient background, background/launcher/connectors pages, view lifecycle, or
+# chat widgets could only be caught by hand. This gates them on packages/ui
+# changes. Mirrors ui-e2e-gate.yml (lean bun workspace + Playwright Chromium;
+# the runners self-bundle from source, so no dist build is needed).
+#
+# fused-wake is keyless too: it self-skips (exit 0 + ::notice::) unless the
+# prebuilt libwakeword + hey-eliza models are staged, so on this runner it
+# documents the skip instead of silently not existing.
