   feeds.
3. Apply feed filter rules last.

ForDetailed each feed, set:pages:

1. Address and Port09-Feeds-Smart-Port-i-MLAT.md
2. Format10-Feed-Filter.md
3. ConnectionType
4. Enabled

After saving, verify:

1. feed connection status,
2. increasing message counters,
3. non-empty AircraftList.json.11-Merged-Feeds.md

2. Merged Feeds

Use Merged Feeds to build one logical output from multiple sources.

Operating model:

1. Keep raw inputs in Feeds.
2. Publish user-facing output through merged feeds when needed.

3. Feed Filter

Apply filters carefully:

1. First confirm raw input works without filters.
2. Then narrow using ICAO/MLAT and other rules.
3. Re-check list and map after each filter change.

4. Common issue: selected feed still shows too much

Symptom: selecting a specific feed still shows aircraft from other feeds.

Checklist:

1. Verify feedId mapping in output data.
2. Verify frontend sends the correct feed parameter.
3. Compare All feeds vs single feed for the same bbox.
4. Repeat test on a second feed for the same user.
5. Remember there is a short stability window: aircraft recently seen by selected feed can remain visible briefly to reduce flicker.
6. For merged feeds, filtering remains anchored to selected feed ID (no automatic expansion to all merged sources).
