-## Current Sprint: v1.3 - OSINT & Fleet Ops
+## Current Sprint: v1.6+ — Validation & Measurement
 
 ### P2 - Normal
-- [ ] Multi-sensor BLE correlation in esp-ctl (zone tracking)
+- [ ] Power consumption measurements using POWERTEST + external meter
 - [ ] Test OTA rollback (flash bad firmware, verify auto-revert)
 - [ ] Create HA webhook automations for deauth_flood / unknown_probe
 
 ### P3 - Low
+- [ ] Deep sleep mode with wake-on-CSI-motion
+- [ ] Battery-optimized duty cycling
 - [ ] Document esp-crab dual-antenna capabilities
 - [ ] Document esp-radar console features
 - [ ] Pin mapping for ESP32-DevKitC V1
 
+## Completed: v1.6 - Power Management
+
+- [x] ESP-IDF power management framework (DFS 240/80 MHz + light sleep)
+- [x] sdkconfig: CONFIG_PM_ENABLE, CONFIG_FREERTOS_USE_TICKLESS_IDLE
+- [x] POWERSAVE command (WiFi modem sleep toggle, NVS persisted, default off)
+- [x] powersave= field in STATUS reply
+- [x] POWERTEST save/restore of powersave state
+- [x] Deployed to fleet, NVS persistence verified
+
+## Completed: v1.5 - Event Handling & NVS Persistence
+
+- [x] EVENT packet parsing in watch daemon (motion, wifi_reconnect, powertest)
+- [x] Sensor heartbeat tracking (offline/online detection, configurable timeout)
+- [x] sensor_events table with indexed queries (`esp-ctl osint events`)
+- [x] HA webhooks for sensor_offline, sensor_online, motion_change
+- [x] NVS persistence for SCANRATE and PROBERATE commands
+- [x] Sensor events count in `esp-ctl osint stats`
+
+## Completed: v1.4 - Multi-Sensor & Validation
+
+- [x] Multi-sensor BLE correlation in esp-ctl (zone tracking by source sensor)
+- [x] Zone tracking with EMA RSSI (`esp-ctl osint zones`, `device_zones` table)
+- [x] Per-sensor breakdown in MAC profile (`esp-ctl osint mac`)
+- [x] POWERTEST command (7-phase power profiling with EVENT markers)
+- [x] Parallel OTA fleet updates (`esp-fleet ota --parallel`)
+
 ## Completed: v1.3 - Security & OSINT
 
 - [x] HMAC command authentication (firmware + esp-ctl/esp-cmd/esp-fleet/esp-ota)

 ## Notes
 
 - Adaptive threshold varies by environment; 0.001-0.01 is a good starting range

-- EVENT packets now include sensor hostname: `EVENT,<hostname>,motion=... rate=... wander=...`
