+## Mesh ingestor contracts (stable interfaces)
+
+This repo’s ingestion pipeline is split into:
+
+- **Python collector** (`data/mesh_ingestor/*`) which normalizes packets/events and POSTs JSON to the web app.
+- **Sinatra web app** (`web/`) which accepts those payloads on `POST /api/*` ingest routes and persists them into SQLite tables defined under `data/*.sql`.
+
+This document records the **contracts that future providers must preserve**. The intent is to enable adding new providers (MeshCore, Reticulum, …) without changing the Ruby/DB/UI read-side.
+
+### Canonical node identity
+
+- **Canonical node id**: `nodes.node_id` is a `TEXT` primary key and is treated as canonical across the system.
+- **Format**: `!%08x` (lowercase hex, 8 chars), for example `!abcdef01`.
+- **Normalization**:
+  - Python currently normalizes via `data/mesh_ingestor/serialization.py:_canonical_node_id`.
+  - Ruby normalizes via `web/lib/potato_mesh/application/data_processing.rb:canonical_node_parts`.
+- **Dual addressing**: Ruby routes and queries accept either a canonical `!xxxxxxxx` string or a numeric node id; they normalize to `node_id`.
+
+Note: non-Meshtastic providers will need a strategy to map their native node identifiers into this `!%08x` space. That mapping is intentionally not standardized in code yet.
+
+### Ingest HTTP routes and payload shapes
+
+Future providers should emit payloads that match these shapes (keys + types), which are validated by existing tests (notably `tests/test_mesh.py`).
+
+#### `POST /api/nodes`
+
+Payload is a mapping keyed by canonical node id:
+
+- `{ "!abcdef01": { ... node fields ... } }`
+
+Node entry fields are “Meshtastic-ish” (camelCase) and may include:
+
+- `num` (int node number)
+- `lastHeard` (int unix seconds)
+- `snr` (float)
+- `hopsAway` (int)
+- `isFavorite` (bool)
+- `user` (mapping; e.g. `shortName`, `longName`, `macaddr`, `hwModel`, `role`, `publicKey`, `isUnmessagable`)
+- `deviceMetrics` (mapping; e.g. `batteryLevel`, `voltage`, `channelUtilization`, `airUtilTx`, `uptimeSeconds`)
+- `position` (mapping; `latitude`, `longitude`, `altitude`, `time`, `locationSource`, `precisionBits`, optional nested `raw`)
+- Optional radio metadata: `lora_freq`, `modem_preset`
+
+#### `POST /api/messages`
+

+- Position: `latitude`, `longitude`, `altitude` (floats|nil)
+- Position time: `position_time` (int|nil)
+- Quality: `location_source` (string|nil), `precision_bits` (int|nil), `sats_in_view` (int|nil), `pdop` (float|nil)
+- Motion: `ground_speed` (float|nil), `ground_track` (float|nil)
+- RF/meta: `snr`, `rssi`, `hop_limit`, `bitfield`, `payload_b64` (string|nil), `raw` (mapping|nil), `ingestor`, `lora_freq`, `modem_preset`
+
+#### `POST /api/telemetry`
+
+Single telemetry payload:
+
+- Required: `id` (int), `rx_time` (int), `rx_iso` (string)
+- Node: `node_id` (canonical string|nil), `node_num` (int|nil), `from_id`, `to_id`
+- Time: `telemetry_time` (int|nil)
+- Packet: `channel` (int), `portnum` (string|nil), `bitfield` (int|nil), `hop_limit` (int|nil)
+- RF: `snr` (float|nil), `rssi` (int|nil)
+- Raw: `payload_b64` (string; may be empty string when unknown)
+- Metrics: many optional snake_case keys (`battery_level`, `voltage`, `temperature`, etc.)
+- Meta: `ingestor`, `lora_freq`, `modem_preset`
+
+#### `POST /api/neighbors`
+
+Neighbors snapshot payload:
+
+- Node: `node_id` (canonical string), `node_num` (int|nil)
+- `neighbors`: list of entries with `neighbor_id` (canonical string), `neighbor_num` (int|nil), `snr` (float|nil), `rx_time` (int), `rx_iso` (string)
+- Snapshot time: `rx_time`, `rx_iso`
