 ### Tailscale Tag Application
 
-Tailscale ACL tags can only be requested when a device registers. tailscaled's declarative `--config` file has no field for them (see the `TAILSCALE_TAGS` row above). `tailscale set` has no `--advertise-tags` flag, and changing the tags of a registered node needs a fresh login. So when `TAILSCALE_TAGS` holds valid tags, the supervisor lets tailscaled start unauthenticated and registers it itself. Flags below are confirmed against tailscale v1.102.4, the version `Dockerfile.tailscale` ships.

So when `TAILSCALE_TAGS` holds valid tags, the supervisor lets tailscaled start unauthenticated and registers it itself. Flags below are confirmed against tailscale v1.104.2, the version `Dockerfile.tailscale` ships.
 
 1. `renderTailscaleConfig` writes the config with `version`, `hostname` and `"locked": false`, and no `authKey`. The auth key goes to `/tmp/gameplane-tunnel-tailscale-authkey` (mode 0600). `locked` must be false: `ipn.ConfigVAlpha.Locked` defaults to true, and a locked config makes tailscaled reject every CLI prefs change.
 2. `tailscaled` is started as usual, with `--socket=/tmp/gameplane-tunnel-tailscaled.sock`. Its Linux default, `/run/tailscale/tailscaled.sock`, can't be created by the non-root distroless image; this is the same reasoning as `playitSocketPath`. The `tailscale` CLI, bundled in `Dockerfile.tailscale` alongside `tailscaled`, reaches it over the same socket via `--socket=`. With no auth key, tailscaled waits in `NeedsLogin`.
