+## Settings
+
+All parameters are configurable via the web UI (**Open → Settings** card) and take effect immediately without reinstalling:
+
+| Parameter | Default | Description |
+|---|---|---|
+| Custom Server URL | *(empty)* | Control server URL for [Headscale](https://headscale.net/) or other self-hosted servers. Leave blank to use Tailscale's official servers. |
+| Auth Key | *(empty)* | Pre-authentication key (`tskey-auth-...`). Cleared automatically after first successful connection. Leave blank to authenticate via browser. |
+| HTTP Proxy Port | `8080` | Port for the outbound HTTP/HTTPS proxy. |
+| SOCKS5 Proxy Port | `1080` | Port for the outbound SOCKS5 proxy. |
+| Accept DNS | `off` | Passes `--accept-dns=true` to `tailscale up`. Allows the tailnet to push DNS settings to the camera. Off by default to avoid overriding the camera's DNS configuration. Not available on `armv7hf_acap3`. |
+| Accept Routes | `off` | Passes `--accept-routes=true` to `tailscale up`. Allows the camera to use subnet routes advertised by other nodes in the tailnet. Not available on `armv7hf_acap3`. |
+
+---
+
+
+All non-ROOT variants expose two local proxy endpoints that route outbound traffic through the Tailscale tunnel. The ports are configurable via **Settings → HTTP Proxy Port / SOCKS5 Proxy Port** in the web UI.
+
+### HTTP CONNECT Proxy — `http://127.0.0.1:8080` (default)
+
+Routes HTTP and HTTPS traffic. Set this wherever an HTTP/HTTPS proxy field is available on the camera:
+
+| Location | Field | Value |
+|---|---|---|
+| System → Network → Global proxies | HTTP proxy | `http://127.0.0.1:<port>` |
+| System → Network → Global proxies | HTTPS proxy | `http://127.0.0.1:<port>` |
+| System → MQTT → Broker | HTTP proxy | `http://127.0.0.1:<port>` |
+| System → MQTT → Broker | HTTPS proxy | `http://127.0.0.1:<port>` |
+
+### SOCKS5 Proxy — `127.0.0.1:1080` (default)
+
+For ACAP apps or services that support SOCKS5, set their proxy to `127.0.0.1:<port>`.
+
+> The active proxy addresses are always shown in the **Proxy Configuration** card of the web UI.
+
+> If you change a port that is already in use by another process, the app will log an error and exit rather than silently falling back to a different port.

-For **full networking features**, use the **ROOT** version on Axis OS < 12.
+For **full kernel networking**, use the **ROOT** version. Note: ROOT mode requires Axis OS 11.11–11.x — Axis OS 12 and later removed root access for third-party applications.

+## Roadmap
+
+### AXIS OS 13 Preparation
+
+AXIS OS 13 (scheduled for September 2026) introduces several breaking changes that affect all ACAP applications. The following items are required to maintain compatibility. See the full [AXIS OS 13 breaking changes](https://www.axis.com/for-developers/news/AXIS-OS-13-breaking-changes) announcement for details.
+
+- [ ] **Recompile for 64-bit time (Y2038)** - AXIS OS 13 switches to a 64-bit time interface. All ACAP apps must be recompiled against the updated SDK. Cameras with incompatible apps installed will roll back the OS upgrade rather than proceed.
+- [ ] **Sign the ACAP via the Axis ACAP Portal** - AXIS OS 13 removes the ability to install unsigned applications in production environments. The app must be submitted and signed through the official Axis ACAP Portal to remain installable.
+- [ ] **Migrate to Manifest Schema v2** - The `manifest.json` must use Manifest Schema v2, including an explicit declaration of compatible AXIS OS versions, to satisfy the new signing and compatibility requirements.
+- [ ] **Audit for executable stack usage** - Any ACAP compiled with an executable stack must be recompiled to comply with the new security restrictions in AXIS OS 13.
+- [ ] **Verify web UI works over HTTPS** - AXIS OS 13 enforces HTTPS-only connections by default. The bundled web UI must be tested to confirm it functions correctly under this constraint.
+
+### General Improvements
+
+- [x] **Accept DNS from tailnet toggle** - Add an opt-in setting to the settings page that passes `--accept-dns=true` to `tailscale up`. Defaults to off to prevent Tailscale from overriding `resolv.conf` on cameras that don't need MagicDNS.
+- [x] **Accept routes toggle** - Add an opt-in setting that passes `--accept-routes=true` to `tailscale up`, allowing the camera to use subnet routes advertised by other nodes in the tailnet.
+- [ ] **Switch to tiny-tailscale binaries** - Evaluate replacing the bundled `tailscale` and `tailscaled` binaries with [tiny-tailscale](https://github.com/iamromulan/tiny-tailscale) builds. These combine both into a single binary, strip unused features, and are significantly smaller (~43% reduction), reducing install size and memory footprint across all architectures.

+ * ACAP parameter bridge for Tailscale VPN (userspace variant).
+ *
+ * Responsibilities:
+ *  1. Read Tailscale parameters from the ACAP parameter store (axparameter).
+ *  2. Write them to CONFIG_FILE so the shell script can source them.
+ *  3. Launch the shell script (Tailscale_VPN_run) as a child process.
+ *  4. On any parameter change: rewrite CONFIG_FILE and do a full stop+restart
+ *     of the child so the new config is picked up.
+ *     Rapid changes within 300 ms are coalesced into a single restart.
+ *  5. Watchdog: if the child exits unexpectedly, restart it.
+ *
+ * Runs as the unprivileged 'sdk' ACAP user — no root required.

+ * ACAP parameter bridge for Tailscale VPN (userspace variant).

+ * Responsibilities:
+ *  1. Read Tailscale parameters from the ACAP parameter store (axparameter).
+ *  2. Write them to CONFIG_FILE so the shell script can source them.
+ *  3. Launch the shell script (Tailscale_VPN_run) as a child process.
+ *  4. On any parameter change: rewrite CONFIG_FILE and do a full stop+restart
+ *     of the child so the new config is picked up.
+ *     Rapid changes within 300 ms are coalesced into a single restart.
+ *  5. Watchdog: if the child exits unexpectedly, restart it.
