- config/logging.php: Themen-Channels billing, ki, monitoring, market als daily-Dateien mit gemeinsamer Aufbewahrung (LOG_DAILY_DAYS), Stack-Default auf daily; Channel `testing` für die Suite. - Fachliche Log-Aufrufe in Billing, KI-Jobs, OperationalAlert und Kursdaten auf Log::channel() umgestellt. - phpunit.xml + TestCase: Suite schreibt ausschließlich nach testing-YYYY-MM-DD.log; LogChannelsTest sichert die Konfiguration. - docs/weiteres: Decision-Update Duplicate-Content entfernt (überholt durch Roadmap-Anhang 2), Decision-Update Verlinkung & Backlinks als Referenz wieder abgelegt, README-Index nachgezogen.
