AIS sends ship types as ITU-R M.1371 codes, so vessels_in_area grouped
"70", "74" and "79" as three types, and type: "tanker" matched nothing on
feeds that send codes. Codes now read as the family the vessel cards already
show (CARGO, TANKER, TUG), for rows, group_by and the type filter. The code
table moves to src/data/vesselTypes.js, which has no i18n import, so the
server-side tools can use it; vesselLabels re-exports it.
A destination with no letters ("0", "---") now counts as unknown.
Live, Singapore: "most by type: CARGO (3), TANKER (3), PASSENGER (1)"; "how
many tankers near Singapore" found 3.

AIS type 0 means "not available" (ITU-R M.1371), but the source keeps it
as '0', so group_by: 'type' listed "0" as a type and understated
unknown_count. vessels_in_area rows now report it as null, and a
regression fixture mixes type 0 with Cargo and Tanker.

aircraft_in_area and vessels_in_area return at most 200 rows, so a client
asked which operators dominate an area, or the average altitude there, could
only estimate from a truncated sample. Both tools now take an optional
group_by (aircraft: operator, origin_country, type_code; ships: type,
destination) and stats (airborne altitude and speed for aircraft, speed for
ships). Each is computed over every match before rows are capped. Breakdowns
list the ten largest groups plus other and unknown counts, and the summary
names the three largest.

The vessel source accepts an optional area and sends it as lat, lon and
radius_km. The vessel layer asks for the area the camera shows (centered
on the middle of the screen, sized by camera height), or every vessel
from high enough up, and asks again when the view moves or zooms by a
quarter of that radius. vessels_in_area names its area too. Servers that
hold every vessel may ignore the area; callers still keep only what is
inside it.
Tool answers with something to show now include data.view: the view with
the matching layers on, the area framed from above or a single aircraft or
satellite followed, and the link that opens it. Area framing moves to
src/tools/views.js so links and answers frame alike.
Vessel tools read the source's default of the newest 12,000 vessels while
the server keeps up to 50,000, so a lookup could miss a vessel still held.
They now ask for more than any server keeps and receive everything it has.
Add vessels_in_area, find_vessel and get_vessel_track over the live
vessel source, and a ships section in situation_brief. Without an AIS
key the source's own message reaches clients as an unavailable feed.
