## Summary
Fixes#450 — staging deployment flaky due to container not shutting down
cleanly.
## Root Causes
1. **Server never closed DB on shutdown** — SQLite WAL lock held
indefinitely, blocking new container startup
2. **`httpServer.Close()` instead of `Shutdown()`** — abruptly kills
connections instead of draining them
3. **No `stop_grace_period` in compose configs** — Docker sends SIGTERM
then immediately SIGKILL (default 10s is often not enough for WAL
checkpoint)
4. **Supervisor didn't forward SIGTERM** — missing
`stopsignal`/`stopwaitsecs` meant Go processes got SIGKILL instead of
graceful shutdown
5. **Deploy scripts used default `docker stop` timeout** — only 10s
grace period
## Changes
### Go Server (`cmd/server/`)
- **Graceful HTTP shutdown**: `httpServer.Shutdown(ctx)` with 15s
context timeout — drains in-flight requests before closing
- **WebSocket cleanup**: New `Hub.Close()` method sends `CloseGoingAway`
frames to all connected clients
- **DB close on shutdown**: Explicitly closes DB after HTTP server stops
(was never closed before)
- **WAL checkpoint**: `PRAGMA wal_checkpoint(TRUNCATE)` before DB close
— flushes WAL to main DB file and removes WAL/SHM lock files
### Go Ingestor (`cmd/ingestor/`)
- **WAL checkpoint on shutdown**: New `Store.Checkpoint()` method,
called before `Close()`
- **Longer MQTT disconnect timeout**: 5s (was 1s) to allow in-flight
messages to drain
### Docker Compose (all 4 variants)
- Added `stop_grace_period: 30s` and `stop_signal: SIGTERM`
### Supervisor Configs (both variants)
- Added `stopsignal=TERM` and `stopwaitsecs=20` to server and ingestor
programs
### Deploy Scripts
- `deploy-staging.sh`: `docker stop -t 30` with explicit grace period
- `deploy-live.sh`: `docker stop -t 30` with explicit grace period
## Shutdown Sequence (after fix)
1. Docker sends SIGTERM to supervisord (PID 1)
2. Supervisord forwards SIGTERM to server + ingestor (waits up to 20s
each)
3. Server: stops poller → drains HTTP (15s) → closes WS clients →
checkpoints WAL → closes DB
4. Ingestor: stops tickers → disconnects MQTT (5s) → checkpoints WAL →
closes DB
5. Docker waits up to 30s total before SIGKILL
## Tests
All existing tests pass:
- `cd cmd/server && go test ./...` ✅
- `cd cmd/ingestor && go test ./...` ✅

## Summary
Several features and fixes from a live deployment of the Go v3.0.0
backend.
### geo_filter — full enforcement
- **Go backend config** (`cmd/server/config.go`,
`cmd/ingestor/config.go`): added `GeoFilterConfig` struct so
`geo_filter.polygon` and `bufferKm` from `config.json` are parsed by
both the server and ingestor
- **Ingestor** (`cmd/ingestor/geo_filter.go`, `cmd/ingestor/main.go`):
ADVERT packets from nodes outside the configured polygon + buffer are
dropped *before* any DB write — no transmission, node, or observation
data is stored
- **Server API** (`cmd/server/geo_filter.go`, `cmd/server/routes.go`):
`GET /api/config/geo-filter` endpoint returns the polygon + bufferKm to
the frontend; `/api/nodes` responses filter out any out-of-area nodes
already in the DB
- **Frontend** (`public/map.js`, `public/live.js`): blue polygon overlay
(solid inner + dashed buffer zone) on Map and Live pages, toggled via
"Mesh live area" checkbox, state shared via localStorage
### Automatic DB pruning
- Add `retention.packetDays` to `config.json` to delete transmissions +
observations older than N days on a daily schedule (1 min after startup,
then every 24h). Nodes and observers are never pruned.
- `POST /api/admin/prune?days=N` for manual runs (requires `X-API-Key`
header if `apiKey` is set)
```json
"retention": {
"nodeDays": 7,
"packetDays": 30
}
```
### tools/geofilter-builder.html
Standalone HTML tool (no server needed) — open in browser, click to
place polygon points on a Leaflet map, set `bufferKm`, copy the
generated `geo_filter` JSON block into `config.json`.
### scripts/prune-nodes-outside-geo-filter.py
Utility script to clean existing out-of-area nodes from the database
(dry-run + confirm). Useful after first enabling geo_filter on a
populated DB.
### HB column in packets table
Shows the hop hash size in bytes (1–4) decoded from the path byte of
each packet's raw hex. Displayed as **HB** between Size and Type
columns, hidden on small screens.
## Test plan
- [x] ADVERT from node outside polygon is not stored (no new row in
nodes or transmissions)
- [x] `GET /api/config/geo-filter` returns polygon + bufferKm when
configured, `{polygon: null, bufferKm: 0}` when not
- [x] `/api/nodes` excludes nodes outside polygon even if present in DB
- [x] Map and Live pages show blue polygon overlay when configured;
checkbox toggles it
- [x] `retention.packetDays: 30` deletes old transmissions/observations
on startup and daily
- [x] `POST /api/admin/prune?days=30` returns `{deleted: N, days: 30}`
- [x] `tools/geofilter-builder.html` opens standalone, draws polygon,
copies valid JSON
- [x] HB column shows 1–4 for all packets in grouped and flat view

* refactor: remove all packets_v SQL fallbacks — store handles all queries
Remove DB fallback paths from all route handlers. The in-memory
PacketStore now handles all packet/node/analytics queries. Handlers
return empty results or 404 when no store is available instead of
falling back to direct DB queries.
- Remove else-DB branches from handlePacketDetail, handleNodeHealth,
handleNodeAnalytics, handleBulkHealth, handlePacketTimestamps, etc.
- Remove unused DB methods (GetPacketByHash, GetTransmissionByID,
GetPacketByID, GetObservationsForHash, GetTimestamps, GetNodeHealth,
GetNodeAnalytics, GetBulkHealth, etc.)
- Remove packets_v VIEW creation from schema
- Update tests for new behavior (no-store returns 404/empty, not 500)

Sensor nodes embed telemetry (battery_mv, temperature_c) in their advert
appdata after the null-terminated name. This commit adds decoding and
storage for both the Go ingestor and Node.js backend.
Changes:
- decoder.go/decoder.js: Parse telemetry bytes from advert appdata
(battery_mv as uint16 LE millivolts, temperature_c as int16 LE /100)
- db.go/db.js: Add battery_mv INTEGER and temperature_c REAL columns
to nodes and inactive_nodes tables, with migration for existing DBs
- main.go/server.js: Update node telemetry on advert processing
- server db.go: Include battery_mv/temperature_c in node API responses
- Tests: Decoder telemetry tests (positive, negative temp, no telemetry),
DB migration test, node telemetry update test, server API shape tests

SQLite stores these as REAL on some instances. Go *int scan silently
fails, dropping the entire observer row (404 on detail, missing from list).

Channels with garbage-decrypted names (pre-#197 data still in DB) are now
filtered at the API level using the same non-printable character heuristic
from #197. Applied in both Node.js server.js and Go server (store.go, db.go).
No data is deleted — only filtered from API responses.

#184: Strip non-printable chars (<0x20 except tab/newline) from ADVERT
names in Go server decoder, Go ingestor decoder, and Node decoder.js.
#185: Add visual (N) badge next to node names when multiple nodes share
the same display name (case-insensitive). Shows in list, side pane, and
full detail page with 'also known as' links to other keys.
#186: Add packetsLast24h field to /api/stats response.
#187#188: Cache runtime.ReadMemStats() with 5s TTL in Go server.
#189: Temporarily patch HTMLCanvasElement.prototype.getContext during
L.heatLayer().addTo(map) to pass { willReadFrequently: true }, preventing
Chrome console warning about canvas readback performance.
Tests: 10 new tests for buildDupNameMap + dupNameBadge (143 total frontend).
Cache busters bumped.

- #178: Use strftime ISO 8601 format instead of datetime() for observation
timestamps in all SQL queries (v3 + v2 views). Add normalizeTimestamp()
helper for non-v3 paths that may store space-separated timestamps.
- #179: Strip internal fields (decoded_json, direction, payload_type,
raw_hex, route_type, score, created_at) from ObservationResp. Only
expose id, transmission_id, observer_id, observer_name, snr, rssi,
path_json, timestamp — matching Node.js parity.
- #180: Remove _parsedDecoded and _parsedPath from node detail
recentAdverts response. These internal/computed fields were leaking
to the API. Updated golden shapes.json accordingly.
- #181: Use mux route template (GetPathTemplate) for perf stats path
normalization, converting {param} to :param for Node.js parity.
Fallback to hex regex for unmatched routes. Compile regexes once at
package level instead of per-request.

The poller only queried WHERE t.id > sinceID, which missed new
observations added to transmissions already in the store. The trace
page was correct because it always queries the DB directly.
Add IngestNewObservations() that polls observations by o.id watermark,
adds them to existing StoreTx entries, re-picks best observation, and
invalidates analytics caches. The Poller now tracks both lastTxID and
lastObsID watermarks.
Includes tests for v3, v2, dedup, best-path re-pick, and
GetMaxObservationID.

db.GetChannels() queried packets_v (observation-level rows) ordered by
observation timestamp and always overwrote lastMessage. When an older
message had a later re-observation, it would overwrite the correct
latest message with stale data.
Fix: query transmissions table directly (one row per unique message)
ordered by first_seen. This ensures lastMessage always reflects the
most recently sent message, not the most recently observed one.
Also fix db.GetChannelMessages() to use first_seen ordering with
schema-aware queries (v2/v3), and add missing distCache/subpathCache
invalidation on packet ingestion.

The frontend sends ISO timestamps to filter by observation time.
Go was filtering by transmission first_seen which missed packets
with recent observations but old first_seen. Now converts ISO to
unix epoch and queries the observations table directly.
