+- Contact routing now uses canonical route fields: `direct_path`, `direct_path_len`, `direct_path_hash_mode`, plus optional `route_override_*`.
+- The contact/API surface also exposes backend-computed `effective_route`, `effective_route_source`, `direct_route`, and `route_override` so send logic and UI do not reimplement precedence rules independently.
+- Legacy `last_path`, `last_path_len`, and `out_path_hash_mode` are no longer part of the contact model or API contract.
+- Route precedence for direct-message sends is: explicit override, then learned direct route, then flood.
+- The learned direct route is sourced from radio contact sync (`out_path`) and PATH/path-discovery updates, matching how firmware updates `ContactInfo.out_path`.
+- Advertisement paths are informational only. They are retained in `contact_advert_paths` for the contact pane and visualizer, but they are not used as DM send routes.
 - `path_len` in API payloads is always hop count, not byte count. The actual path byte length is `hop_count * hash_size`.

 ### ACK and Repeat Detection
 
 **Direct messages**: Expected ACK code is tracked. When ACK event arrives, message marked as acked.
 
-Outgoing DMs send once immediately, then may retry up to 2 more times in the background if still unacked. Retry timing follows the radio's `suggested_timeout` from `PACKET_MSG_SENT`, and the final retry is sent as flood even when a routing override is configured. DM ACK state is terminal on first ACK: sibling retry ACK codes are cleared so one DM should not accumulate multiple delivery confirmations from different retry attempts.

+
+ACKs are not a contact-route source. They drive message delivery state and may appear in analytics/detail surfaces, but they do not update `direct_path*` or otherwise influence route selection for future sends.
 
 **Channel messages**: Flood messages echo back through repeaters. Repeats are identified by the database UNIQUE constraint on `(type, conversation_key, text, sender_timestamp)` — when an INSERT hits a duplicate, `_handle_duplicate_message()` in `packet_processor.py` adds the new path and, for outgoing messages only, increments the ack count. Incoming repeats add path data but do not change the ack count. There is no timestamp-windowed matching; deduplication is exact-match only.

+On Linux systems, this is the recommended installation method if you want RemoteTerm set up as a persistent systemd service that starts automatically on boot and restarts automatically if it crashes. Run the installer script from the repo root. It runs as your current user, installs from wherever you cloned the repo, and prints a quick-reference cheatsheet when done — no separate service account or path juggling required.
 
 ```bash
-# Create service user
-sudo useradd -r -m -s /bin/false remoteterm
-
-# Install to /opt/remoteterm
-sudo mkdir -p /opt/remoteterm
-sudo cp -r . /opt/remoteterm/
-sudo chown -R remoteterm:remoteterm /opt/remoteterm
-
-# Install dependencies
-cd /opt/remoteterm
-sudo -u remoteterm uv venv
-sudo -u remoteterm uv sync
-
-# If deploying from a source checkout, build the frontend first
-sudo -u remoteterm bash -lc 'cd /opt/remoteterm/frontend && npm install && npm run build'

-# If deploying from the release zip artifact, frontend/prebuilt is already present

+The script interactively asks which transport to use (serial auto-detect, serial with explicit port, TCP, or BLE), whether to build the frontend locally or download a prebuilt copy, whether to enable the bot system, and whether to set up HTTP Basic Auth. It handles dependency installation (`uv sync`), validates `node`/`npm` for local builds, adds your user to the `dialout` group if needed, writes the systemd unit file, and enables the service. After installation, normal operations work without any `sudo -u` gymnastics:
 
-```ini

-[Service]
-Type=simple
-User=remoteterm

-- The final DM retry is intentionally sent as flood via `reset_path(...)`, even when a routing override exists.
+- Direct-message send behavior is intended to emulate `meshcore_py.commands.send_msg_with_retry(...)` when the radio provides an expected ACK code: stage the effective contact route on the radio, send, wait for ACK, and on the final retry force flood via `reset_path(...)`.
+- Non-final DM attempts use the contact's effective route (`override > direct > flood`). The final retry is intentionally sent as flood even when a routing override exists.
 - DM ACK state is terminal on first ACK. Retry attempts may register multiple expected ACK codes for the same message, but sibling pending codes are cleared once one ACK wins so a DM should not accrue multiple delivery confirmations from retries.

+- `SettingsRadioSection.tsx` also exposes `multi_acks_enabled` as a checkbox for the radio's extra direct-ACK transmission behavior.
 - Advert-location control is intentionally only `off` vs `include node location`. Companion-radio firmware does not reliably distinguish saved coordinates from live GPS in this path.
 - The advert action is mode-aware: the radio settings section exposes both flood and zero-hop manual advert buttons, both routed through the same `onAdvertise(mode)` seam.
 - Mesh discovery in the radio section is limited to node classes that currently answer discovery control-data requests in firmware: repeaters and sensors.

+This is intentional. In the sidebar, unread direct messages for actual contact conversations are treated as mention-equivalent for badge styling. That means both the Contacts section header and contact unread badges themselves use the highlighted mention-style colors for unread DMs, including when those contacts appear in Favorites. Repeaters do not inherit this rule, and channel badges still use mention styling only for real `@[name]` mentions.
