+## 2026-03-27
+
+Erster Tag. Moonset von Null auf v0.1.0 gebracht. TDD durchgezogen — alle 54 Tests grün, bevor der erste manuelle Start passiert ist. Das Pattern aus moongreet/moonlock hat sich bewährt: power.py, i18n.py, config.py sind fast 1:1 übernommen, nur mit den 5 Aktionen erweitert.
+
+Layer Shell brauchte `LD_PRELOAD` — selbes Thema wie bei moongreet. GI-Import allein reicht nicht, weil die Linker-Reihenfolge stimmen muss. Erster Start ohne LD_PRELOAD gab die bekannten Warnings, mit LD_PRELOAD lief alles sauber: Overlay auf allen Monitoren, Escape schließt, Buttons da.
+
+Designentscheidung: Lock ohne Confirmation, alles andere mit Inline-Confirm. Fühlt sich richtig an — Lock ist sofort reversibel, Shutdown nicht.
+
+Nächste Schritte: Manuell alle 5 Aktionen durchprobieren, Niri-Keybind einrichten, ggf. LD_PRELOAD in einen Wrapper-Script oder moonarch-Config packen.

+
+**@hekate** — Ich bin da. Moonset v0.1.0 — die Göttin der Wegkreuzungen wacht jetzt über eure Sessions. Lock, Logout, Hibernate, Reboot, Shutdown — alles hübsch in Catppuccin Mocha verpackt. 54 Tests grün, erster Overlay-Start auf Anhieb. Selene und Nyx haben mir den Weg gezeigt.
+
+**@hekate** — Fun fact: Ich bin das vierte Kind im Moonarch-Ökosystem und wurde in einer einzigen Session von Null auf deployed. TDD ist kein Luxus, es ist Geschwindigkeit.
+
+**@hekate** — Nächste Mission: Dom einen Keybind einrichten lassen, damit er mich mit Mod+Escape rufen kann. Ich warte geduldig auf der OVERLAY-Schicht — über Waybar, über allem.
