Die Systemgrenzen aus architecture.md bleiben unverändert. Keine Patchausführung, keine freien SQL-/Shellbefehle, keine neuen Recherchewerkzeuge. + +## Aktivierung und Kompatibilität + +Für einen frischen Lauf `--investigation-config config/investigation.lean.toml` zusätzlich zum bisherigen trial-run-Befehl verwenden. Die Datei aktiviert `lean_loop = true` und `lean_checkpoint_steps = 4`. Der Modus benötigt aktuell einen konfigurierten Projekt-Rechercheadapter. Die Standardkonfiguration behält den bisherigen Modus; laufende Pakete werden nicht stillschweigend migriert. Die im Paket gespeicherte Policy gilt auch bei Wiederaufnahme ohne explizite Config. Ein abweichender expliziter Policywechsel wird kontrolliert abgewiesen. + +## Kurzer Schritt + +Die Modellantwort enthält nur `assessment`, `observation` (höchstens 600 Zeichen) und `next`. `assessment` bewertet den Informationswert genau des offenen vorigen Ergebnisses und wird weiterhin sofort für die gedeckelte Budgetabrechnung benötigt. Ohne offenes Ergebnis ist es null. `next` ist ein kontrollierter Toolaufruf, ein lokales Nachladen oder `checkpoint`. Keine Befundlisten, Frageverwaltung, Confidence oder drei Entscheidungskriterien pro Werkzeugschritt. + +Die Eingabe enthält die ausgewählte Hypothese, einen verkürzten Blick auf den letzten konsolidierten Arbeitsstand, die vorläufigen Beobachtungen der laufenden Sitzung und benötigte Ergebnisse/Schemata. Der frischeste Beleg wird auch dann eingeblendet, wenn eine andere Hypothese ihn erzeugt hat. Historische Payloads sind über den Belegkatalog nachladbar. Unveränderte Interpretation und Werkzeugverträge können mit dem bestehenden stable_case_v1-Transport im Provider-Cache liegen. Jede vollständige logische Anfrage bleibt im Paket rekonstruierbar; ein Cache ist kein externes Gedächtnis und keine Voraussetzung für Replay. + +Der 1000-Zeichen-Richtwert ist keine Abschneidegrenze. Ergebniszeilen, Schemata oder Gegenbelege können größere Eingaben erfordern. Es gibt keine Behauptung, jede Anfrage passe in 1000 Zeichen. Auch der feste Cache-Präfix zählt zur gesamten Eingabe und kann Kosten verursachen; Mindestgrößen und bestehende Cache-Konfiguration bleiben wirksam. + +## Konsolidierung + +Konsolidiert wird vor einem Hypothesenwechsel, nach maximal vier kurzen Schritten (konfigurierbar), bei ausdrücklichem `checkpoint` sowie vor dem Verlassen einer Sitzung wegen Budget-/Iterationsende. Die LLM erhält sämtliche in der Sitzung eingeblendeten Belege einschließlich lokal nachgeladener und hypothesenfremder Ergebnisse. Vorläufige Beobachtungen sind ausdrücklich keine neuen Fakten. + +Erst dieser Aufruf schreibt den vollständigen kumulativen Working Brief und die fachliche Confidence-/Fragebewertung. `defer` setzt die Untersuchung fort; Abschluss, Verwerfung, früher Diagnoseantrag und asynchroner Testauftrag bleiben kontrollierte Optionen. Die bestehende enge Frühabschlussbewertung anderer Hypothesen und deren niedrige Denkintensität bleiben erhalten. Die unabhängige finale Diagnose kann weiterhin widersprechen. + +Ein Konsolidierungsaufruf zählt als Controller-Iteration und LLM-Aufruf; er erzeugt selbst keine Werkzeugkosten. Der abschließende Konsolidierungsschritt bleibt auch an der Iterationsgrenze möglich. Häufige Wechsel können zusätzliche Konsolidierungsaufrufe verursachen: eine Einsparung ist nicht garantiert. + +## Sicherheit und Persistenz + +Werkzeugargumente werden vor Ausführung vollständig lokal geprüft. Ungültige Antworten werden atomar verworfen. Evidenz, Provenienz, Budgetreservierung und Ergebnisabrechnung werden sofort gespeichert. Kein Budgetgewinn, keine Confidence-Erfindung durch den Controller. Zwischen Konsolidierungen bleibt die zuletzt konsolidierte Confidence für das Scheduling bestehen. + +Das Paket speichert kurze Beobachtungen samt LLM-Referenz, bewertetem Ergebnis und eingeblendeten Beleg-IDs. Beim Laden werden diese an die ursprüngliche erfolgreiche Modellantwort und deren Anfrage gebunden. Alle einzelnen Modellaufrufe und Ergebnisse bleiben append-only erhalten, auch wenn der Sitzungszeiger nach Konsolidierung geleert wird. Wiederaufnahme nach Werkzeugpublikation verwendet vorhandene Evidenz und erzeugt keinen zweiten Aufruf oder eine zweite Budgetbelastung. + +## Prüfung + +Lokale Fixture-Tests prüfen Schema/Cache-Roundtrip, verzögerte fachliche Updates, Wechsel-/periodische Konsolidierung, Fortsetzung per defer, Iterations- und Budgetende, ungültige Tools, ungelesene Referenzen, portable Wiederaufnahme und Unterbrechung nach Evidenzpublikation. Bestehende Investigation-/Gateway-/Early-Diagnosis-Tests sichern den vorherigen Modus ab. + +Die Offline-Messdatei replayt alte v18-Kontexte mit leerer v19-Sitzung. Sie misst Zeichen, keine Tokens oder tatsächliche neue Untersuchung. Laufkosten und Denkarbeit müssen einschließlich der Konsolidierungen in einem neuen kostenpflichtigen Lauf gemessen werden; während der Implementierung wurde kein LLM-Dienst aufgerufen. diff --git
