"""Bausteine fuer Trigger: Pydantic-Eingaben -> echte RichChk-Objekte.

Das ist das Herzstueck. Ein Trigger besteht aus *Bedingungen* (conditions) und
*Aktionen* (actions). Hier werden die tolerant getippten Eingaben von Claude in die
echten RichChk-Modelle uebersetzt, mit hilfreichen Fehlermeldungen.

Unterstuetzte CONDITION-Typen (Feld `type`):
  - always                 : immer wahr (Standard-Bedingung)
  - never                  : nie wahr
  - elapsed_time           : seit Spielstart sind N Sekunden vergangen
        Felder: seconds, comparator (AT_LEAST|AT_MOST|EXACTLY)
  - countdown_timer        : der Countdown-Timer vergleicht mit N Sekunden
        Felder: seconds, comparator
  - bring                  : Spieler hat N Einheiten an einer Location
        Felder: player, comparator, amount, unit, location
  - command                : Spieler kommandiert N Einheiten (ganze Karte)
        Felder: player, comparator, amount, unit
  - kill                   : Spieler hat N Einheiten eines Typs getoetet
        Felder: player, comparator, amount, unit
  - deaths                 : Spieler hat N Todesfaelle eines Einheitentyps
        Felder: player, comparator, amount, unit
  - accumulate             : Spieler hat N Ressourcen
        Felder: player, comparator, amount, resource (ORE|GAS|ORE_AND_GAS)
  - opponents              : Spieler hat N verbleibende Gegner
        Felder: player, comparator, amount

Unterstuetzte ACTION-Typen (Feld `type`):
  - display_text           : Text einblenden.  Felder: text
  - set_mission_objectives : Missionsziele setzen.  Felder: text
  - play_wav               : WAV abspielen.  Felder: wav_path (in-MPQ-Pfad), duration_ms?
  - create_unit            : Einheiten erzeugen.  Felder: player, amount, unit, location
  - kill_unit_at_location  : Einheiten toeten.  Felder: player, amount, unit, location
  - remove_unit_at_location: Einheiten entfernen. Felder: player, amount, unit, location
  - move_unit              : Einheiten bewegen.
        Felder: player, amount, unit, location (Quelle), destination (Ziel)
  - give_units             : Einheiten uebergeben.
        Felder: player (von), target_player (an), amount, unit, location
  - set_resources          : Ressourcen setzen.
        Felder: player, modifier (SET_TO|ADD|SUBTRACT), amount, resource
  - set_deaths             : Todeszaehler setzen.
        Felder: player, modifier, amount, unit
  - set_countdown_timer    : Countdown-Timer setzen.  Felder: seconds, modifier
  - pause_timer / unpause_timer : Countdown-Timer pausieren/fortsetzen
  - run_ai_script          : AI-Skript ausfuehren.  Felder: ai_script (4-Zeichen-Code)
  - run_ai_script_at_location : AI-Skript an Location.  Felder: ai_script, location
  - center_view            : Kamera zentrieren.  Felder: location
  - minimap_ping           : Minimap-Ping.  Felder: location
  - set_alliance_status    : Allianz setzen.
        Felder: player (Ziel-Gruppe), alliance_status (ENEMY|ALLY|ALLIED_VICTORY)
  - victory                : Mission gewonnen
  - defeat                 : Mission verloren

Hinweis "Transmission mit Portrait": RichChk hat (Stand dieser Version) kein
High-Level-Modell fuer die Transmission-/TalkingPortrait-Aktion. Baue einen
Funkspruch stattdessen aus `play_wav` + `display_text` (+ optional `center_view`)
zusammen. Siehe README.
