+#!/bin/bash
+#
+# Rebuild the Mac Mini Cloudflare tunnel as a locally-managed tunnel.
+#
+# WHY:
+#   The original `mana-server` tunnel was created via the Cloudflare
+#   dashboard, which makes it remotely-managed: cloudflared loads its
+#   ingress rules from Cloudflare's API and ignores the local config
+#   file's `ingress:` section. There is no documented way to convert
+#   a remotely-managed tunnel to locally-managed (cloudflared#843
+#   has been open for years), so the only path to single-source-of-
+#   truth file management is to delete and recreate the tunnel.
+#
+# WHAT THIS DOES (in order):
+#   1. Snapshot baseline HTTP statuses for every hostname currently
+#      in cloudflared-config.yml — for an after/before diff at the end
+#   2. Backup the existing credentials .json (cannot be restored after
+#      delete since the cloud config also goes away, but useful for
+#      cross-referencing the old tunnel ID)
+#   3. Delete the existing tunnel via `cloudflared tunnel delete -f`
+#   4. Create a new tunnel with the same name `mana-server`. Cloudflare
+#      generates a new UUID and writes a new credentials .json
+#   5. Patch the new tunnel ID + credentials path into both
+#      ~/projects/mana-monorepo/cloudflared-config.yml AND
+#      ~/.cloudflared/config.yml
+#   6. For each hostname in the config file, run
+#      `cloudflared tunnel route dns -f mana-server <hostname>` so the
+#      Cloudflare DNS CNAME for the hostname re-points at the new tunnel
+#   7. launchctl kickstart -k cloudflared to pick up the new credentials
+#   8. Wait for the tunnel to register, then HTTP-probe every hostname
+#      and report any that didn't come back up
+#
+# DOWNTIME:
+#   ~30-90 seconds total. Step 3 (delete) immediately blackholes ALL
+#   public mana.how URLs. Steps 4-6 take ~30-60s. Step 7 brings the
+#   tunnel back up. After that DNS edge propagation may add another
+#   10-30s for some Cloudflare PoPs.
+#
+# ROLLBACK:
+#   The old tunnel is gone forever after step 3. There is no rollback
+#   to the old tunnel ID. If something breaks during this script, the
+#   recovery path is to re-run this same script (it's idempotent for
+#   already-routed hostnames thanks to the -f flag on the dns command).
+#
+# RUN ON: the mana-server itself, NOT from a dev box. The cloudflared
+# CLI needs the cert.pem from `cloudflared tunnel login` which lives in
+# ~/.cloudflared/ on the server.
