 ## Spätere Phasen
 
 ### Phase 4
+Phase-4 Status: Monitor-Window-Betriebsmodell gelandet (Wave 4F-C Abschluss).
+
+Gelandete Wellen (4F):
+- Monitor-Windows mit Overlap, Priority/Zone-Bias und Auto-Record/Decode pro Window
+- Candidate-Gating im Capture-Span + Refinement-Plan-Input
+- Window-Statistiken + Outcome-Summaries in Debug/API (`/api/refinement`)
+- Decision/Admission-Reason-Tags mit `window:*` + `window-zone:*`
+
+Nächste Ausbaustufe (später):
 - breitbandige Multi-Span-Profile
 - 20-80 MHz konkrete Betriebsmodi
 - adaptive Quality-of-Service

 The long-term target is that you describe *what the system should do* (for example broad-span monitoring intent, preferred signal families, auto-record/decode priorities), while the engine decides *how* to allocate surveillance, refinement and decoding budgets.
 
-Phase-4 groundwork: `monitor_windows` allows multi-span gating within a single capture span; it is used to accept/reject candidates and inform refinement plans without changing the acquisition center/rate.
+Phase-4 status (monitor-window operating model): `monitor_windows` gates candidates inside a capture span, supports overlapping windows with priority/zone bias, and can auto-record/decode per window without retuning. Window stats + summaries now surface in `/api/refinement`, and decision/admission reasons include window tags/zone tags for traceability.
