 ### Added
-- macOS CoreWLAN WiFi sensing adapter with user guide (`a6382fb`)
+- **Cross-platform RSSI adapters** — macOS CoreWLAN (`MacosCoreWlanScanner`) and Linux `iw` (`LinuxIwScanner`) Rust adapters with `#[cfg(target_os)]` gating
+- macOS CoreWLAN Python sensing adapter with Swift helper (`mac_wifi.swift`)
+- macOS synthetic BSSID generation (FNV-1a hash) for Sonoma 14.4+ BSSID redaction
+- Linux `iw dev <iface> scan` parser with freq-to-channel conversion and `scan dump` (no-root) mode
+- ADR-025: macOS CoreWLAN WiFi Sensing (ORCA)
+
+### Fixed
+- Removed synthetic byte counters from Python `MacosWifiCollector` — now reports `tx_bytes=0, rx_bytes=0` instead of fake incrementing values

+## Pre-Merge Checklist
+
+Before merging any PR, verify each item applies and is addressed:
+
+1. **Tests pass** — `cargo test` (Rust) and `python -m pytest` (Python) green
+2. **README.md** — Update platform tables, crate descriptions, hardware tables, feature summaries if scope changed
+3. **CHANGELOG.md** — Add entry under `[Unreleased]` with what was added/fixed/changed
+4. **User guide** (`docs/user-guide.md`) — Update if new data sources, CLI flags, or setup steps were added
+5. **ADR index** — Update ADR count in README docs table if a new ADR was created
+6. **Docker Hub image** — Only rebuild if Dockerfile, dependencies, or runtime behavior changed (not needed for platform-gated code that doesn't affect the Linux container)
+7. **Crate publishing** — Only needed if a crate is published to crates.io and its public API changed (workspace-internal crates don't need publishing)
+8. **`.gitignore`** — Add any new build artifacts or binaries
+

+### macOS WiFi (RSSI Only)
+
+Uses CoreWLAN via a Swift helper binary. macOS Sonoma 14.4+ redacts real BSSIDs; the adapter generates deterministic synthetic MACs so the multi-BSSID pipeline still works.
+
+```bash
+# Compile the Swift helper (once)
+swiftc -O v1/src/sensing/mac_wifi.swift -o mac_wifi
+
+# Run natively
+./target/release/sensing-server --source macos --http-port 3000 --ws-port 3001 --tick-ms 500
+```
+
+See [ADR-025](adr/ADR-025-macos-corewlan-wifi-sensing.md) for details.
+
+### Linux WiFi (RSSI Only)
+
+Uses `iw dev <iface> scan` to capture RSSI. Requires `CAP_NET_ADMIN` (root) for active scans; use `scan dump` for cached results without root.
+
+```bash
+# Run natively (requires root for active scanning)
+sudo ./target/release/sensing-server --source linux --http-port 3000 --ws-port 3001 --tick-ms 500
+```

 ### ESP32-S3 (Full CSI)
 
 Real Channel State Information at 20 Hz with 56-192 subcarriers. Required for pose estimation, vital signs, and through-wall sensing.
