+# ── LINE webhook route hot-reload workaround ─────────────────────────────────
+# Bug: openclaw/openclaw#49803 — LINE (and other webhook-based channels) return
+# 404 on cold start because the bundler splits runtime.ts into two chunks. The
+# chunk that registers LINE routes and the chunk the HTTP server uses to look up
+# routes both initialise the same global "route registry" object — but whichever
+# chunk runs first creates the object without the fields the other chunk expects,
+# so they end up referencing different registries. Result: routes are registered
+# successfully (no error logged) but the HTTP server can't find them → 404.
+#
+# After a config hot-reload the channel restarts and re-registers routes into the
+# correct registry, so the 404 goes away. The workaround below triggers that
+# hot-reload automatically 20 seconds after the gateway starts.
+#
+# How it works:
+#   1. Waits 20 s for the gateway to fully start and load all channel plugins.
+#   2. Writes a temporary "_reloadTs" field into openclaw.json — the gateway's
+#      file-watcher sees the change and hot-reloads the LINE channel.
+#   3. Removes the temporary field 5 s later (clean-up).
+#
+# This is a background process — it does NOT block gateway startup.
+# Remove this block once openclaw/openclaw#49803 is fixed upstream and the
+# upstream fix is merged and shipped in a release we build from.
+#
+# Upstream PRs tracking the real fix:
+#   - openclaw/openclaw#53642 (bundle-split registry mismatch fix)
+#   - openclaw/openclaw#54686 (syncPluginRegistry at runtime boundaries)
