# One-shot launcher for the scheduled Brain-OS-Audit (KAR-859, ordered 2026-07-06).
# Fires 2026-07-07 after the weekly Fable budget reset. It does NOT run the audit
# itself — it (1) notifies Kais and (2) injects a trigger into the live `aria` tmux
# session. The Aria session then performs the rigorous, repeated Fable-5 verification
# (per EXECUTION-SPEC.md pre-flight) and runs the full audit with all tools.
#
# Rationale: the shell can't do deep reasoning / file edits / Linear / Fable-gating;
# the Claude-Code session can. So the launcher stays trivial+reliable and delegates.

Schritt 2: Fuehre das Fable-5-Pre-Flight aus (config + LIVE-Transcript-Modell pruefen, nicht das Identity-Feld) und verifiziere mehrfach dass Fable 5 laeuft. Wenn Fable NICHT laeuft: pausiere und frag Kais per Telegram (warten / Paid-Credits / auf Opus fahren) — entscheide das NICHT selbst. Wenn Fable laeuft: setze den kompletten Audit (9 Deliverables, KARs deduped, sichere Doc-Edits auf Working-Branch) autonom um und liefere den deutschen Report per Telegram."
