fix(autocall): the QSO in progress outranks the ladder

Six faults from an evening on 60 m, all in the same family: the engine
judging a station by what the log wants from it and forgetting what is
already under way.

- An exchange was abandoned mid-QSO. The reply lands in the same period
  the ladder is re-read, and that period was judged before the reply was
  taken into account, so a better-ranked caller took the slot from a
  station that had just come back to us. The answer is settled first now,
  and our own report counts as being inside the exchange too — which also
  protects a QSO the operator started by hand.
- A station just picked started with misses against it. Its transmit slot
  was unknown until a second decode, and with the parity unknown every
  period counted, including the one spent transmitting to it.
- The freed slot after "it is working somebody else" was thrown away: the
  period's decodes are in hand, so the next station is picked from them
  rather than fifteen seconds later. Never mid-over.
- Auto-call is never armed from a stored setting — not at launch, not on
  a profile switch. It is the one feature that puts the station on the
  air by itself and OpsLog starts with Windows.
- It says what it is waiting for: a wanted station in a QSO with somebody
  else now shows beside the Auto button instead of looking idle.
- Switching profile left the previous logbook's verdicts on screen. The
  worked-index, chase-new and the frontend's cached verdicts are dropped
  when the logbook changes.

FT decodes: distance column, a message addressed to you set whole in
green (the station you are calling keeps a tint — most of what it sends
goes to other people), badge order L / Wkd / WL, list cleared when the
RIG changes band.

Rotor: new world-map compass from EC1KD's design, with the Ultrabeam boom
and second lobe restored and the compact form preserved; the classic dial
is kept and Settings → Rotator chooses between them. Stop no longer
flickers on a rotor standing still — movement was inferred from a degree,
less than the jitter a controller reports at rest.

-      "Auto-call stops calling a station that starts working somebody else. Callability was tested when the station was CHOSEN and never again while it was held, so one picked on its CQ that then answered another caller went on being called for the whole seven attempts — two minutes of transmitting at a station in a QSO that cannot hear it. Its final frame to another station does not count: that one is a period from being free, which is the best moment there is to be calling it. Released with no verdict attached, so it is fair game with a full allowance the moment it CQs again.",
-      "Auto-call now calls only what the decodes list is SHOWING. The filters above it — CQ only, LoTW only, the new-category chips, continents, minimum report, the search box — steer the transmitter as well as the eye: a station filtered off the screen is not called. The panel sends the callsigns it is showing rather than its filter settings, so there is one definition of “shown” and the engine cannot disagree with what is in front of the operator. With the list closed, nothing is filtered.",
-      "PSK Reporter panel: the suggested call offset now always has an answer when there is data. It looked for a clear run of empty slots and said nothing when it found none — which is exactly the case it was built for: a hundred decodes across a 2800 Hz passband leave no gap at all, and the panel drew the whole histogram with no advice under it. Failing a real gap it now names the quietest slot, ties going to the higher offset, and never above the ceiling.",
-      "Auto-call refused nearly every station on the air as “already worked”. It was reading the ENTITY’s verdict as the station’s: “worked” there means the COUNTRY is in the log on this band and mode, so on a band where the operator has most of them, everything decoding was turned away — a trace of one evening shows twenty decodes out of twenty-one refused that way, the watched DXpedition among them. The entity’s verdict now decides what is NEEDED, and the callsign’s own slot decides whether calling it would be a duplicate.",
-      "Auto-call reads a multi-answer line whole. MSHV answers two stations in one transmission and the decoder prints them as one line — “YV5ALI RR73; F4BPO <HK0/PY8WW> -08” — where the second half is a report to us. Reading only the start of it, the engine saw a station working somebody else and dropped the target at the exact moment the DX was answering. The decodes panel already read every segment; the engine now does too, for “is it calling us”, “can it be called” and “is the QSO finished”.",
-      "Auto-call leaves the slot after a QSO to your own 73. The DX’s RR73 is decoded while you are between overs, so the decoder is about to send that 73 in the slot just opening — answering somebody else there switched the DX call mid-sequence, and the frame that closes the contact never went out whole. The next station is picked on the following period instead, fifteen seconds later, and it is still there. It used to hand straight on because the slot is the resource; the slot is worth less than the QSO it spoils."

MSHV répond à deux stations dans une même émission et le décodeur l’imprime sur une seule ligne — « YV5ALI RR73; F4BPO <HK0/PY8WW> -08 » — dont la seconde moitié est un report pour nous. En n’en lisant que le début, le moteur voyait une station occupée avec quelqu’un d’autre et lâchait la cible au moment précis où le DX répondait. Le panneau des décodages lisait déjà chaque segment ; le moteur le fait désormais aussi, pour « est-ce qu’il nous appelle », « peut-on l’appeler » et « le QSO est-il fini ».",

Le RR73 du DX est décodé pendant que vous êtes entre deux émissions : le décodeur s’apprête à envoyer ce 73 dans le créneau qui s’ouvre, et y répondre à quelqu’un d’autre changeait l’indicatif en pleine séquence — la trame qui clôt le contact ne partait jamais entière. La station suivante est désormais choisie à la période d’après, quinze secondes plus tard, et elle est toujours là. Il enchaînait aussitôt parce que le créneau est la ressource ; le créneau vaut moins que le QSO qu’il gâche."
