Part of #1869. ## Problem `observers.radio` keeps only the **last** `MHz,kHz,SF,CR` an observer reported. Once an observer is retuned (say from SF7 to the EU narrow SF8 setting to listen to a neighbouring mesh), every packet it ever heard reads as heard on the new setting, and there is no way to tell an SF7 packet from an SF8 one. ## What this does As #1869 proposes, the packet data model is untouched: the setting of an observation is resolved from its observer and time. **Ingestor** (all schema in `dbschema.Apply`) - `observer_radios`: one row per stretch of time an observer, and each radio of a multi-radio node, stayed on one setting. Every live status extends the current row and a change starts a new one; retained replays never extend a row. On the first run it is seeded with every observer's current radio, which is what the UI already showed for the past. - Settings are stored canonical through `dbschema.CanonicalRadio`, so `869.4320068,62.5,7,5` and `869.432,62.50,7,5` are one setting. - `observation_radios` (`observation_id → rx_radio_id`): multi-radio openHop nodes tag each packet with `rx_radio_id` and list `radios: [{id, radio}]` in their status, so their observations resolve per radio. - The table is sparse: single-radio nodes never send the field, so `observations` and every query that scans it stay untouched. - The row id comes from the observation upsert via `RETURNING id`. - Rows are pruned with their transmissions, and a purged observer takes its history along. **Server** (read-only) - No `AssertReady` change: an absent table reads as empty and is probed again later, the same rule as `advert_route_evidence`. - The history is held in memory. The live poller checks it on every tick (two primary-key lookups), so a retune or a new `rx_radio_id` is known before the observation is broadcast. A full reload runs every 10 min. - `radio` is added to observations, packets, grouped rows (taken from the header observation) and the live feed. - `GET /api/packets?radio=MHz,kHz,SF,CR` filters by setting. - Combined with `observer=`, it means *that* observer heard it on that setting. - A radio query is served from memory instead of falling back to SQL, which would return the window unfiltered. - `GET /api/radios` (named struct) and `radio_history` on `GET /api/observers/{id}`. **Frontend** - Packet filter fields `radio`, `freq`, `bw`, `sf`, `cr`, e.g. `sf == 8` or `freq > 869.5 && bw == 62.5`. - A Radio row in the packet detail and a Radio column in its observations table (only when the server reports one). - A radio history table on the observer page once there is more than one stretch. - `RfParams.radioText` formats the setting. It escapes all five characters and returns non-numeric input as it came, escaped. ## Performance `txMatchesRadio` runs once per observation inside `filterPackets`. - Each observation costs one map lookup by observer id. - Observers with a single stretch (nearly all) answer from that lookup directly. - Retuned observers add a binary search over their few stretches. - Multi-radio observers add one lookup by observation id. - The snapshot is loaded once per filter call. `BenchmarkTxMatchesRadio`, 30K packets / 150K observations (20 observers, 2 of them retuned): ``` BenchmarkTxMatchesRadio-24 602 2056924 ns/op 0 B/op 0 allocs/op ``` Memory is one entry per stretch plus one per multi-radio observation; nothing is added per observation otherwise. ## Tests - **dbschema:** seed runs once, canonical spellings, the tables exist without `observers.radio`. - **ingestor:** - stretches extend and split; canonical spellings do not split - two radios of one node hearing one transmission over two paths each keep their own radio - a retained status does not write history - prune and purge - `rx_radio_id` reaches `PacketData` - **server:** - resolution before, between and after stretches, and with an unknown radio id - `observer` + `radio`, and grouped rows carry `radio` - incremental refresh, `/api/radios`, `radio_history`, missing tables - the benchmark above - **frontend:** the new filter fields in `tests/unit/test-packet-filter.js`, and XSS cases through the real `RfParams.radioText` and the history renderer. - **E2E:** `tests/e2e/test-radio-setting-1869-e2e.js` checks the grouped rows' radio, `sf ==` on the packets page, the detail Radio row and the observer history. It is added to `scripts/non-unit-tests.json` and to shard 2. `go test -race` in `cmd/server`, `cmd/ingestor` and `internal/dbschema` passes, along with `sh test-all.sh`, `eslint@8` (0 errors) and the XSS diff gate. The new E2E test and `test-e2e-playwright.js` pass against the fixture. ## Browser validation This runs on a live instance with six observers, one of them retuned to 869.618/62.5/SF8/CR8: - The packet detail shows `Radio: 869.432 MHz · SF7 · BW 62.5 kHz · CR 4/5`. - `sf == 7` shows 106 of 106 grouped rows and `sf == 8` shows 0 of 107; the SF8 observer has not heard anything yet. - `/api/radios` lists both settings. - No page errors. ## Notes - **The customizer (rule 8)** gets nothing: the only constants are server-side refresh intervals. - **Attribution timing:** packets heard between a retune and the observer's next status message (minutes) are attributed to the previous setting, because a stretch starts when the status is handled.
