+- Added an iOS-only GitHub Actions workflow for an unsigned Simulator app and optional development-signed iPhone IPA.

 ### Changed
@@ -30,13 +36,23 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
 - Separated Ktor HTTP offer/control messages from raw TCP file bytes.
 - Reused one TCP connection for the complete accepted multi-file batch instead of opening one connection per file.
 - Removed per-file flush-and-acknowledgement waits so an accepted batch can stream continuously before one final receiver result.
+- Moved network startup from the Send ViewModel to the Android and Desktop application entry points.
+- Derived the 60-second discovery window from the platform-reported running state.
+- Made Android repair advance through NSD callbacks and made JVM cleanup retain JmDNS instances that fail to close.
+- Restricted discovery Reload and full connection repair to compatible discovery and registration states.
+- Selected the Windows-native discovery backend at Desktop DI startup while retaining JmDNS for macOS and Linux.
+- Used the JDK Foreign Function and Memory API for Windows interop without adding a third-party native bridge.
+- Made Windows discovery process native add and TTL-zero removal notifications so the nearby-device list can update during an active browse.
+- Moved Windows discovery out of its initial loading state as soon as the operating system accepts the asynchronous browse request.
+- Confirmed in an initial Windows 11 Ethernet test that Android and Windows advertisements appeared promptly and were removed after the corresponding app closed.
+- Aligned Kotlin 2.4.10, Android Gradle Plugin 9.1.1, and Gradle 9.3.1 within their documented compatibility ranges while retaining Android API 37.
 - Positioned the project around direct local-network nearby sharing rather than chat or cloud sync.
 
 ### Known limitations
 
 - No stable public release yet.
 - No authentication, encryption, transfer/session token, or cryptographic integrity verification.
-- No byte percentage, speed, ETA, retry, pause/resume, or interrupted-transfer recovery.
+- No speed, ETA, retry, pause/resume, or interrupted-transfer recovery; transfer progress currently shows batch-wide whole-byte percentage.
 - Foreground/background and network-change lifecycle handling are incomplete.
 - Desktop support needs broader operating-system, adapter, firewall, and router validation.
-- Automated transfer coverage is minimal; iOS is inactive.
+- Automated transfer coverage is minimal; iOS physical-device discovery and transfer are unverified.
