docs: record the CI work in the checklist

Adds section 4d covering the missing build gate, the Windows feature gap
that broke the Windows target, the unknown-argument hang, the
hardware-dependent audio test, and the Windows autostart no-op. Also
points the verification section at the GitHub Actions workflows.

+# Scythe: Comprehensive Project & Architecture Guide
+
+This document is the definitive technical reference for developers and AI agents working on the Scythe codebase. It outlines the project's design philosophy, unified binary architecture, hardware encoding pathways, audio subsystem, power management, HUD overlay, and development standards.
+
+---
+
+## 1. Project Overview & Current Status
+
+**Current Version:** `v0.2.18`  
+**License:** Dual MIT / Apache 2.0  
+
+### Repository Topology
+
+| Remote | URL | Role | Status |
+|---|---|---|---|
+| `forgejo` | `https://git.oiupoyt.space/oiupoyt/scythe.git` | Self-hosted primary; source of truth, release assets | Active |
+| `origin` | `https://spearzificial@github.com/spearzificial/scythe.git` | **GitHub development mirror** (currently maintained account) | Active |
+| `gitlab` | `https://gitlab.com/oiupoyt.cat/scythe.git` | Optional mirror | Optional |
+
+**GitHub account policy:** GitHub pushes go to the `spearzificial` account, and `origin` points at that account's repository. The `oiupoyt` GitHub OAuth token is expired, so the old `oiupoyt` repository is not a push target. Always name the account in the remote URL (`https://spearzificial@github.com/...`) so Git selects the correct stored credential when multiple GitHub accounts exist in the credential store.
+
+### Dual-Push Rule
+
+Every push must reach both active remotes:
+
+```bash
+git push origin main
+git push forgejo main
+```
+
+
+Scythe is a cross-platform, ultra-low-overhead desktop screen recorder, instant replay buffer, and livestreamer written in Rust. It delivers functionality comparable to NVIDIA ShadowPlay and GPU Screen Recorder with minimal CPU and GPU overhead.
+
+### Core Capabilities:
+1. **Unified Multicall Binary Architecture**: UI overlay, CLI client, and headless daemon engine are consolidated into a single executable ([`src/main.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/main.rs)) with subcommands (`scythe daemon`, `scythe record`, `scythe save`, etc.) and backward-compatible symlinks (`scythe-daemon`, `scythe-ui`).
+2. **Zero-Copy Hardware Video Encoding**:
+   - **Linux**: FFmpeg VA-API (`h264_vaapi`, `hevc_vaapi`, `av1_vaapi`) with direct DRM DMA-BUF import for Intel and AMD GPUs. Automatic low-power hardware fallback handles drivers lacking `VAEntrypointEncSliceLP`.
+   - **Windows**: Native NVENC, AMD AMF, Intel QuickSync (QSV), and multithreaded software fallbacks via DirectX Graphics Infrastructure (DXGI) desktop duplication.
+3. **High-Fidelity Audio Engine**:
+   - Multi-source routing: System Audio, Microphone, Both, or Muted.
+   - Dual codec support: Native Opus (`AV_CODEC_ID_OPUS`, 48 kHz stereo, 160 kbps, `AV_SAMPLE_FMT_FLT`) as recommended default, with native AAC (`AV_CODEC_ID_AAC`, 48 kHz stereo, 192 kbps, `AV_SAMPLE_FMT_FLTP`) as universal fallback.
+   - Interactive sound verification suite with live dB / percentage VU meters and test tone playback.
+4. **Lock-Free Circular RAM Replay Buffer**:
+   - Continuous lock-free packet ring buffer in system RAM (configurable from 5 seconds to 30 minutes).
+   - Keyframe-aware draining ensures saved MP4 clips begin cleanly on IDR boundaries with zero decoder corruption.
+5. **Smart Power Management**:
+   - AC power connectivity monitoring via Linux `/sys/class/power_supply` and Windows Win32 `GetSystemPowerStatus`.
+   - Dedicated 1-second background power poller thread.
+   - "Power-only" replay mode automatically drains and pauses the replay buffer on battery power to conserve battery life, and seamlessly resumes with keyframe forced resync upon AC connection.
+6. **KAT Square Minimalist Interface**:
+   - Strictly conforms to `DESIGN.md` guidelines: `border-radius: 0 !important;` across all windows, inputs, buttons, and badges.
+   - Obsidian dark palette (`#0b0b0b` / `#111111`) with hairline `#222222` framing and restrained functional accents.
+   - Borderless, shadowless terminal-style notification toasts.
+   - Monospace typography option with integrated `Adwaita Mono` font.
+7. **Screenshot Resolution Presets**:
+   - Intuitive presets: `Native (Source)`, `1080p (FHD)`, `1440p (QHD)`, `2160p (4K UHD)`, `720p (HD)` with hardware-accelerated Lanczos scaling via FFmpeg.
+8. **In-App Auto-Updater**:
+   - Synchronizes against Forgejo releases API (`https://git.oiupoyt.space/api/v1/repos/oiupoyt/scythe/releases/latest`) with automated binary replacement.
+

+
+## 2. High-Level Architecture & Process Model

+
+### Multicall Dispatching:
+- **Daemon Mode**: Invoked when `args[1] == "daemon"`, `args[1] == "--mock"`, or when executed via symlink `scythe-daemon` / `vrec-daemon`. Runs the headless capture and recording engine ([`src/daemon.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/daemon.rs)).
+- **Dispatch uses argv[0], not `current_exe()`**: `current_exe()` reads `/proc/self/exe`, which resolves symlinks to the real file. Every installed alias would therefore report `scythe` and dispatch to the client, so `scythe-daemon` would open the HUD instead of starting the engine. `invoked_stem()` reads argv[0] and falls back to `current_exe()` only when argv[0] has no usable stem.
+- **Client / UI Mode**: Invoked when executed as `scythe`, `scythe-ui`, or with client arguments (`save`, `record`, `screenshot`, `status`, `menu`, etc.). Runs [`src/main.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/main.rs) and launches [`src/overlay_egui.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/overlay_egui.rs).
+
+---
+
+## 3. Inter-Process Communication (IPC)
+
+The protocol is implemented in [`src/ipc.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/ipc.rs).
+
+### Transport Layer:
+- **Linux**: Unix Domain Socket at `$XDG_RUNTIME_DIR/scythe.sock` (with legacy fallback to `/run/user/<UID>/vrec.sock`).
+- **Windows**: Local TCP socket on `127.0.0.1` binding to candidate ports `42069`–`42072` and persisting the active port in `%TEMP%\scythe-ipc.port`.
+
+### Message Payload:
+Packets are framed with a 4-byte little-endian length prefix followed by JSON-serialized structs:
+- **Command (`Command`)**:
+  - `SaveReplay`: Drains the circular buffer and muxes an MP4 replay.
+  - `StartRecording` / `StopRecording` / `ToggleRecording`: Controls manual recording.
+  - `StartStreaming` / `StopStreaming` / `ToggleStreaming`: Controls RTMP broadcasting.
+  - `ToggleAudio`: Toggles microphone/system audio mute state.
+  - `CycleAudioMode`: Cycles through System -> Mic -> Both -> Muted.
+  - `ToggleCursor`: Inverts cursor visibility state and triggers capture synchronization.
+  - `ShowOverlay`: Opens the HUD overlay via the daemon if it is not already running (`scythe --show-overlay`). Distinct from `--menu`, which toggles an already-open overlay closed.
+  - `ReloadConfig`: Live-reloads configuration changes without restarting the daemon unless video parameters change.
+  - `PowerStateChanged(bool)`: Internal notification dispatched by the power poller when AC state transitions.
+  - `GetStatus`: Requests the current `DaemonStatus`.
+  - `StopDaemon`: Triggers clean daemon shutdown.
+- **DaemonStatus (`DaemonStatus`)**:
+  - `is_recording`: bool
+  - `recording_duration_sec`: u64

+## 4. Video Capture Subsystem
+
+Capture sources implement the [`FrameSource`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/capture/mod.rs#L21) trait located in [`src/capture/mod.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/capture/mod.rs).
+
+### Frame Representation:
+```rust
+pub enum Frame {
+    Raw {
+        width: u32,
+        height: u32,
+        stride: u32,
+        data: Arc<Vec<u8>>,
+    },
+    DmaBuf {
+        fd: std::os::fd::RawFd,
+        width: u32,
+        height: u32,
+        stride: u32,
+        format: u32,
+        modifier: u64,
+        offset: u32,
+    },
+    D3D11Texture {
+        handle: usize,
+        width: u32,
+        height: u32,
+    },
+}
+```
+
+### Platform Implementations:
+1. **Wayland ([`src/capture/wayland.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/capture/wayland.rs) & [`src/capture/wayland_stream.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/capture/wayland_stream.rs))**:
+   - Uses `xdg-desktop-portal` and PipeWire screencast stream.
+   - Negotiates DMA-BUF memory buffers (`SPA_DATA_DmaBuf`) for zero-copy GPU video encoding.
+   - Falls back to shared memory buffers (`SPA_DATA_MemPtr`) when DMA-BUF is unavailable.
+2. **X11 ([`src/capture/x11.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/capture/x11.rs))**:
+   - Uses MIT-SHM (`xcb::shm`) for direct shared-memory frame transfer from the X server.
+3. **Windows ([`src/capture/windows.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/capture/windows.rs))**:
+   - Uses the DirectX Graphics Infrastructure (DXGI) Desktop Duplication API (`IDXGIOutputDuplication`).
+   - Iterates through all display adapters and outputs to probe and select the active desktop.
+   - Uses a single Direct3D 11 staging texture (`D3D11_USAGE_STAGING`) with `D3D11_CPU_ACCESS_READ` for low-latency GPU readback.
+   - Tightly packs rows into BGRA format if GPU pitch padding is detected.
+   - Ensures fallback / idle frames generate opaque black (`[0, 0, 0, 255]`) to prevent uninitialized green chroma artifacts.
+4. **Mock Capture ([`src/capture/mock.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/capture/mock.rs))**:
+   - Generates simulated 1080p frames for headless unit tests and CI runners where no display server is attached.
+
+---
+
+## 5. Video Encoding Pipeline
+
+The video encoder module is located in [`src/encoder.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/encoder.rs).
+
+### Linux Encoder (`VaapiEncoder`):
+- Uses FFmpeg libavcodec with VA-API hardware acceleration (`h264_vaapi`, `hevc_vaapi`, `av1_vaapi`).
+- Direct DRM DMA-BUF Import: Zero-copy surface creation via `vaCreateSurfacesFromProperties` for Intel and AMD GPUs.
+- Color Standards: ITU-R BT.709 color primaries (`AVCOL_PRI_BT709`), transfer characteristics (`AVCOL_TRC_BT709`), and MPEG limited range (`AVCOL_RANGE_MPEG`).
+- SIMD Color Space Conversion: When software fallback is required, `sws_scale` operates with `SWS_FAST_BILINEAR` and explicit ITU-709 coefficient mapping.
+
+### Windows Encoder (`WindowsHwEncoder`):
+- Hardware Probing Priority:
+  - H.264: `h264_nvenc` -> `h264_amf` -> `h264_qsv` -> `libx264`
+  - HEVC: `hevc_nvenc` -> `hevc_amf` -> `hevc_qsv` -> `libx265`
+  - AV1: `av1_nvenc` -> `av1_amf` -> `av1_qsv` -> `libsvtav1`
+- Standardized Pixel Format: NV12 (`AV_PIX_FMT_NV12`) across hardware encoders, with YUV420P fallback.
+- Color Conversion: Converts captured BGRA to NV12 using `sws_scale` configured with ITU-R BT.709 matrix and full-range to limited-range mapping (`sws_setColorspaceDetails`), eliminating washed-out colors and green screen bugs.
+- Low Latency Settings: Rate control VBR with burst ceiling, zero B-frames (`max_b_frames = 0`), ultrafast tuning, and 1-second GOP size (`gop_size = fps`).
+
+---
+
+## 6. Audio Subsystem
+
+Audio capture and conversion is implemented in [`src/capture/audio.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/capture/audio.rs) and [`src/encoder.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/encoder.rs).
+
+### Pipeline:
+1. **Capture**:
+   - **Linux**: Uses PulseAudio/PipeWire `parec` targeting `@DEFAULT_MONITOR@` (for system audio loopback) and `@DEFAULT_SOURCE@` (for microphone input) with a 20ms low-latency buffer.
+   - **Windows**: Direct WASAPI loopback capture using the `cpal` crate.
+2. **Channel Downmixing & Resampling**:
+   - Downmixes 5.1 and 7.1 surround sound to stereo using center and surround coefficients:
+     ```
+     L = FL + 0.707 * C + 0.707 * SL + 0.5 * LFE
+     R = FR + 0.707 * C + 0.707 * SR + 0.5 * LFE
+     ```
+   - Resamples arbitrary input sample rates to 48,000 Hz using linear interpolation and soft-clipping limiting (`tanh` curve).
+3. **Encoding (`AudioEncoder`)**:
+   - **Opus (`AV_CODEC_ID_OPUS`)**: Native Opus stereo at 160 kbps, 48 kHz with float sample format (`AV_SAMPLE_FMT_FLT`). Primary recommended standard.
+   - **AAC (`AV_CODEC_ID_AAC`)**: Native AAC stereo at 192 kbps, 48 kHz with planar float format (`AV_SAMPLE_FMT_FLTP`). Universal fallback standard.
+   - Microsecond-accurate PTS rebasing aligns audio packets against video IDR keyframes.
+4. **Interactive Verification & Live VU Meters**:
+   - The UI includes live decibel / percentage VU meters for both system sound and microphone.
+   - Integrated test suite (`test mic` and `test sys` with automated chime playback) allows users to immediately verify sound capture without running external applications.
+
+---
+
+## 7. Lock-Free RAM Ring Buffer & Power Management
+
+Implemented in [`src/ring.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/ring.rs), [`src/daemon.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/daemon.rs), and [`src/config.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/config.rs).
+
+### Buffer Mechanics:
+- Keeps encoded video and audio packets in RAM without writing to disk during active buffer mode.
+- Fixed Capacity: Capacity is calculated dynamically from duration (seconds) * target framerate * safety factor. On low-power hardware, capacity is tightly bounded to conserve memory.
+- **Keyframe-Aware Pruning**:
+  - Replay clips must always begin with an IDR keyframe to prevent visual corruption.
+  - When the circular buffer reaches maximum capacity, packets are dropped starting from the oldest non-keyframe sequence up to the next IDR keyframe boundary.
+- Drain Operation: When `Command::SaveReplay` is received, the buffer packets are cloned into an asynchronous channel without blocking the capture and encoding threads.
+
+### AC Power Management:
+- **Connectivity Detection**: `ScytheConfig::is_ac_power_connected()` inspects `/sys/class/power_supply/*/online` on Linux and calls `GetSystemPowerStatus` on Windows.
+- **Poller Thread**: A dedicated 1-second background thread continuously monitors AC power changes.
+- **Automatic Buffer Gating**: When `autostart_power_only` is enabled:
+  - On battery power loss: The replay buffer is automatically paused, drained of existing frames, and a toast notification (`power lost, replay paused`) is dispatched.
+  - On AC connection restore: Replay buffering automatically resumes, forces an encoder keyframe, and dispatches a notification (`power restored, replay resumed`).
+
+---
+
+## 8. Muxer & Livestreaming
+
+Implemented in [`src/muxer.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/muxer.rs).
+
+### MP4 Container Muxing (`Muxer`):
+- Wraps FFmpeg libavformat to produce universal MP4 files (`.mp4`) containing H.264/HEVC/AV1 video and Opus/AAC audio.
+- Emits faststart headers (`+faststart`) to place the `moov` atom at the beginning of the file for instant streaming and playback.
+- Rebases PTS and DTS timestamps to zero for both video and audio streams at file initialization.
+- Automatic Collision Handling: Formats filenames as `Replay-HH-MM-SS_DD-MM-YYYY.mp4` or `Recording-HH-MM-SS_DD-MM-YYYY.mp4` and resolves conflicts via incremental suffixes (`_1`, `_2`).
+
+### RTMP Livestreaming (`spawn_stream_worker`):
+- Connects to RTMP endpoints (Twitch, YouTube, Kick, Custom RTMP).
+- Encapsulates video and audio NAL units into FLV/RTMP transport on a dedicated worker thread with non-blocking channel dispatch.
+
+---
+
+## 9. In-Game HUD Overlay & Notifications
+
+Implemented in [`src/overlay_egui.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/overlay_egui.rs).
+
+### Design System: KAT Square Minimalist:
+- Strictly adheres to `DESIGN.md`:
+  - **`border-radius: 0 !important;`**: Zero rounded corners or pill badges anywhere in the interface.
+  - **Obsidian Dark Palette**: `#0b0b0b` root background, `#111111` surface panels, `#222222` hairline borders.
+  - **Restrained Accents**: Functional emerald (`#10b981`), red (`#ef4444`), cyan (`#38bdf8`), and vendor themes (AMD, NVIDIA, Intel).
+  - **Monospace Typography**: Full support for `Adwaita Mono` / `JetBrains Mono` with an interface toggle.
+
+### Views:
+- **Main HUD**:
+  - Rolldown / swipe animated dropdown menus (`ui.ctx().animate_bool(...)` over 180ms) for Replay, Record, and Broadcast.
+  - Quick actions with drop shadow framing.
+- **Settings View**:
+  - File Information: Output directory with native folder pickers.
+  - Video Parameters: Resolution scaling, FPS (15 to 360), bitrate (5 to 150 Mbps), codec (H.264, HEVC, AV1), color range (Full vs Limited), low-power recording mode.
+  - Audio: Mode routing, volume sliders (0-150%), Opus/AAC codec choice, and live verification test suite.
+  - Screenshot: Resolution presets (`Native`, `1080p`, `1440p`, `2160p`, `720p`), format (`PNG` vs `JPEG`), and cursor capture toggle.
+  - General: Theme accents, 8 global keybinds with interactive recording listener, compact `Reset Hotkeys` button, and typography toggle.
+- **Notification Toasts (`ShadowPlayToastApp`)**:
+  - Borderless, shadowless terminal-style card.
+  - Obsidian `#111111` fill with 2px vertical accent rule and 6px status dot.
+  - Uppercase monospace title, lowercase metadata subtitle, and 2px hairline progress countdown line.
+
+---
+
+## 10. Global Hotkeys & Window Hooks
+
+Implemented in [`src/hotkey.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/hotkey.rs) and [`src/hyprland_binds.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/hyprland_binds.rs).
+
+### Keybind Registry:
+1. Menu Overlay: `Alt+Z`
+2. Save Instant Replay: `Ctrl+Shift+R`
+3. Start / Stop Recording: `Ctrl+Shift+F9`
+4. Pause / Resume Recording: `Ctrl+Shift+F8`
+5. Take Screenshot: `Ctrl+Shift+S`
+6. Toggle Mouse Cursor: `Ctrl+Shift+F10`
+7. Mute / Unmute Microphone: `Ctrl+Shift+M`
+8. Mute / Unmute System Audio: `Ctrl+Shift+N`
+
+### Dispatch Strategies:
+1. **Hyprland Direct IPC**: Registers binds dynamically using `hyprctl keyword bind` to bypass Wayland global hotkey restrictions. Watches `hyprland.conf` modifications and auto-reapplies.
+2. **Universal Desktop**: Uses the `global-hotkey` crate for standard Windows and X11 hotkey registration.
+
+---
+
+## 11. Configuration Management
+
+Implemented in [`src/config.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/config.rs).
+
+### File Locations:
+- Linux: `~/.config/scythe/config.json`
+- Windows: `%APPDATA%\scythe\config.json`
+
+### Autostart Integration:
+`ScytheConfig::apply_autostart_system(enable_replay, enable_overlay)` manages:
+1. Systemd user service: `systemctl --user enable/disable scythe-daemon.service`.
+2. Standard XDG autostart desktop entries in `~/.config/autostart/scythe-daemon.desktop` and `scythe-overlay.desktop`.
+
+Linux only. The Windows path is a no-op: there is no registry `Run` key write in either the overlay toggle or the NSIS installer, so the autostart switch in the UI currently has no effect on Windows.
+
+### Retired Settings (v0.2.18 cleanup):
+These keys were accepted by the settings UI and persisted to disk, but nothing in the capture, encoder, or daemon paths ever read them. They were removed from `ScytheConfig` and the corresponding UI controls were deleted, so the overlay no longer presents options that do nothing:
+
+| Retired key | Why it was removed |
+|---|---|
+| `capture_source` | Capture always selected the focused monitor; window/region modes were never implemented |
+| `replay_storage` | Replay buffer is always RAM-backed; the disk path was never built |
+| `change_resolution`, `resolution_w`, `resolution_h` | Encoder always used native capture dimensions |
+| `container_format` | Muxer always writes MP4 |
+| `show_scroll_lock_led` | No LED driver integration existed |
+| `autostart_on_game` | No game-detection layer existed |
+| `save_folder_by_game`, `name_by_game` | No game detection; filenames are timestamp-based |
+| `language`, `ui_color_theme` | No translation layer or theme engine; `accent_color` drives the real palette |
+| `record_enabled` | Dead field superseded by runtime `is_recording` state |
+
+Unknown keys in an existing `config.json` are ignored by serde, so upgrading does not break saved configurations. `scythe` rewrites the file without these keys on the next save.
+
+---
+
+## 12. In-App Auto-Updater
+
+Implemented in [`src/updater.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/updater.rs).
+
+### Workflow:
+1. Queries the self-hosted Forgejo release API:
+   `GET https://git.oiupoyt.space/api/v1/repos/oiupoyt/scythe/releases/latest`
+   (Falls back to GitHub API if Forgejo is unreachable).
+2. Parses SemVer strings and checks if `is_newer(latest, CURRENT_VERSION)`.
+3. Downloads the singular platform package:
+   - Linux: `scythe-v<version>-linux-x86_64.tar.gz`
+   - Windows: `scythe-v<version>-windows-x86_64.zip` (includes standalone portable FFmpeg DLLs).
+4. Atomically swaps the executable in `~/.local/bin/scythe` or `%USERPROFILE%\.local\bin\scythe.exe`.
+
+---
+
+## 13. Verification, Testing & Cross-Compilation
+
+### Local Linux Commands:
+```bash
+# Type check all targets
+cargo check --all-targets
+
+# Run the complete unit test suite (27 tests)
+cargo test
+
+# Strict clippy lint verification
+cargo clippy --all-targets -- -D warnings
+
+# Build optimized Linux release binary
+cargo build --release
+
+# Install release binary and symlinks to ~/.local/bin
+bash install.sh
+
+# Run end-to-end integration test suite
+bash tests/e2e_test.sh
+```
+
+`tests/e2e_test.sh` treats a running daemon as a resource it borrows rather than deletes. Unix sockets cannot be re-linked: removing the path entry of a live daemon leaves the kernel socket bound but unreachable, and the session stays broken until that process dies.
+
+The script therefore:
+1. probes liveness by connecting to the socket directly (`scythe --status` cannot be used for this, because it calls `ensure_daemon_running()` and would spawn a daemon while probing);
+2. records the running daemon's command line and working directory;
+3. sends `StopDaemon` and waits for the socket to disappear, aborting without unlinking if it will not stop;
+4. restores that daemon on exit, so a developer's recorder survives a test run.
+
+### Windows Cross-Compilation (from Linux Host):
+```bash
+FFMPEG_DIR="$HOME/.local/share/ffmpeg-win64/ffmpeg-n9.0-latest-win64-gpl-shared-9.0" \
+PKG_CONFIG_PATH="$HOME/.local/share/ffmpeg-win64/ffmpeg-n9.0-latest-win64-gpl-shared-9.0/lib/pkgconfig" \
+PKG_CONFIG_ALLOW_CROSS=1 \
+cargo build --release --target x86_64-pc-windows-gnu
+```
+
+### GitHub Actions:
+
+| Workflow | Trigger | Purpose |
+|---|---|---|
+| [`ci.yml`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/.github/workflows/ci.yml) | push to `main`, pull request, manual | Compiles and tests both targets on every push. Linux job: `cargo check --all-targets`, `cargo test`, `cargo clippy -D warnings`, `cargo build --release`, then runs `scythe --help` to prove the binary starts. Windows job: MSYS2 MINGW64 `cargo build --release`. Both binaries upload as artifacts. |
+| [`release.yml`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/.github/workflows/release.yml) | push of a `v*` tag | Packages `.tar.gz`, `.deb`, `.rpm`, `.AppImage` and the NSIS Windows installer, then publishes a GitHub Release. |
+
+The CI workflow is the only thing that compiles the Windows target on a routine basis, and it exists because the Windows build had already rotted: `src/config.rs` calls `GetSystemPowerStatus` but the `windows` crate feature list never enabled `Win32_System_Power`, so `cargo build --target x86_64-pc-windows-gnu` failed with `E0432`. Tag pushes were the only previous trigger, so nothing caught it before a release was attempted.
+
+The `cargo fmt --check` step is advisory (`continue-on-error: true`). The tree has formatting drift that is intentionally not mass-fixed, because reformatting every file would bury the real changes in a diff.
+
+Tests that need real hardware (a live audio server) are opt-in:
+
+```bash
+SCYTHE_HW_TESTS=1 cargo test
+```
+
+---
+
+## 14. Behavioral Rules & Coding Standards
+
+1. **ABSOLUTELY ZERO EMOJIS**: Under no circumstances should emojis be added to code, comments, log outputs, commit messages, or communication.
+2. **File & Symbol Links**: Every file path or code symbol mentioned in communication must be formatted as a clickable markdown link using the `file://` scheme (e.g., [`src/encoder.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/encoder.rs)).
+3. **KAT Square Minimalist**: Strict `border-radius: 0 !important;` on all visual elements.
+4. **Dual-Push Rule**: When pushing commits or tags, always push to both active remotes (`origin` for GitHub and `forgejo` for self-hosted):
+   ```bash
+   git push origin <branch>
+   git push forgejo <branch>
+   ```
+5. **Memory Safety & Process Isolation**: Avoid blocking the audio or video capture loops. Use unbounded or high-capacity crossbeam channels for frame dispatch.

 This checklist tracks known bugs, UI refinements, optimizations, and technical debt items across the Scythe codebase.
 
+> **Historical note:** entries recorded before v0.2.18 reference `src/bin/scythe-daemon.rs` and `src/bin/scythe-ui.rs`. Those files were merged into [`src/main.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/main.rs) and [`src/daemon.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/daemon.rs) by the multicall consolidation; the paths are kept as an accurate record of where the work happened at the time.
+
 ---
 
 ## 1. UI Refinements & Imperfections
 
+- [x] **Singular Multicall Binary Architecture (`scythe`)**:
+  - **Issue**: Distributing separate `scythe-daemon` and `scythe-ui` binaries required cross-process path discovery in `$PATH`, complicated Windows bundling with multiple executables, and prevented atomic single-file updates.
+  - **Resolution**:
+    - Consolidated daemon engine and UI overlay/CLI into a single binary (`scythe`) in [src/main.rs](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/main.rs) and [src/daemon.rs](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/daemon.rs).
+    - Implemented multicall dispatch: inspects `argv[0]` and subcommands (`scythe daemon`, `scythe [options]`, or symlinks `scythe-daemon` / `scythe-ui`).
+    - Configured [install.sh](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/install.sh) with backward-compatible symlinks.
+    - Updated release packages: both Linux and Windows distributions now ship a single executable.
+
 - [x] **Screenshot Resolution Presets (Native, 1080p, 1440p, 2160p, 720p) & Lanczos Downscaling**:

 ## 3. Reliability & Bug Fixes
 
+- [x] **Gray Screen Recording & Mock Fallback Startup Race Condition**:
+  - **Issue**: At system boot or when logging into the session, `scythe-daemon` started before `xdg-desktop-portal` finished registering on D-Bus. After failing to acquire portals within 3 seconds, the daemon silently fell back to `MockCapture` (hardcoded to emit flat gray `RGB(64, 64, 64)` frames), permanently capturing a blank gray screen on subsequent recordings and replays.
+  - **Resolution**:
+    - Updated [src/bin/scythe-daemon.rs](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/bin/scythe-daemon.rs) so that the daemon never silently traps the user into `MockCapture` unless the explicit `--mock` CLI flag is passed for automated testing.
+    - Added systemd service dependencies (`After=graphical-session.target xdg-desktop-portal.service xdg-desktop-portal-hyprland.service` and `Wants=xdg-desktop-portal.service`) with `Restart=always` and `RestartSec=2` backoff in [install.sh](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/install.sh).
+
+- [x] **GTK3 Retirement, Compile-Time Optimization & Windows Cross-Compilation**:
+  - **Issue**: Legacy GTK3 C-bindings (`gtk`, `gdk`, `glib`, `gtk-layer-shell`) inflated compile times to over 1 minute, consumed heavy build memory, and completely blocked cross-compiling for Windows due to missing MinGW GTK headers.
+  - **Resolution**:
+    - Removed `gtk`, `gdk`, `glib`, `gtk-layer-shell`, and retired [src/settings_ui.rs](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/settings_ui.rs) and the legacy GTK overlay code. Moved `ToastIcon` directly into [src/ipc.rs](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/ipc.rs).
+    - Reduced release compile time by over 60% and unlocked Windows release cross-compilation (`x86_64-pc-windows-gnu`).
+    - Added optimized release profile with thin LTO and symbol stripping in [Cargo.toml](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/Cargo.toml).
+
+- [x] **Forgejo Releases Integration & Auto-Updater Synchronization**:
+  - **Issue**: The auto-updater was hardcoded to GitHub API endpoints, and release binaries were not packaged for both Windows and Linux on the self-hosted Forgejo instance.
+  - **Resolution**:
+    - Updated [src/updater.rs](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/updater.rs) to prioritize Forgejo API releases (`https://git.oiupoyt.space/api/v1/repos/oiupoyt/scythe/releases/latest`) with GitHub fallback.
+    - Cross-compiled release binaries for both Linux (`scythe-v0.2.18-linux-x86_64.tar.gz`) and Windows (`scythe-v0.2.18-windows-x86_64.zip` including full standalone portable FFmpeg DLLs).
+    - Published Release `v0.2.18` directly to Forgejo with assets uploaded.
+
 - [x] **Opus Audio Encoder Implementation & AAC Fallback**:
   - **Issue**: Previously, only AAC audio encoding was supported, despite Opus being the industry standard for low-latency streaming and high-fidelity game recording.
   - **Resolution**: Implemented native `Opus` audio encoding in [src/encoder.rs](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/encoder.rs) (`AudioEncoder::new_with_codec`) using `AV_SAMPLE_FMT_FLT` at 160 kbps with automatic fallback to AAC when unavailable. Dynamically wired into [src/bin/scythe-daemon.rs](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/bin/scythe-daemon.rs) based on `config.audio_codec`. Verified 60 FPS recording with native Opus audio streams in MP4 containers.

-## 5. Verification Commands
+## 4a. Binary Dispatch
+
+- [x] **Symlink Aliases Dispatched to the UI Instead of the Daemon**:
+  - **Issue**: [`src/main.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/main.rs) decided daemon mode from `std::env::current_exe()`, which reads `/proc/self/exe` and resolves symlinks. Because every installed alias points at the real `scythe` file, all of them reported the stem `scythe`, so `scythe-daemon` and `vrec-daemon` fell through to client mode and opened the HUD instead of starting the recording engine. The aliases shipped by [`install.sh`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/install.sh), the `.deb`/`.rpm`/Flatpak packages, and the Hyprland `exec_cmd("scythe-daemon")` autostart line were all affected. A stale pre-consolidation `target/release/scythe-daemon` from an older build masked the bug during local testing.
+  - **Resolution**: Added `invoked_stem()`, which reads argv[0] and only falls back to `current_exe()` when argv[0] has no usable stem. Verified against a packaged tarball: `scythe-daemon` and `vrec-daemon` now report the running-instance guard, while `scythe`, `scythe-ui`, `vrec` and `vrec-ui` open the client.
+
+---
+
+## 4b. Release Pipeline & Packaging Consolidation
+
+- [x] **CI/CD Referenced Binaries That No Longer Build**:
+  - **Issue**: The multicall consolidation removed `scythe-daemon` and `scythe-ui` crate targets, but the release pipeline still copied `target/release/scythe-daemon` and `target/release/scythe-ui`. A tag push would fail at the very first packaging step, so no release could be produced. The same stale paths existed in the GitLab CI artifacts, RPM spec, Flatpak manifest, and both NSIS installers.
+  - **Resolution**:
+    - [`.github/workflows/release.yml`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/.github/workflows/release.yml): tarball, `.deb`, and AppImage now ship the single `scythe` binary plus `scythe-daemon` / `scythe-ui` / `vrec-*` symlinks. The AppImage `AppRun` and the Windows bundle copy only `scythe` / `scythe.exe`.
+    - [`.gitlab-ci.yml`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/.gitlab-ci.yml): artifacts publish `target/release/scythe`; the Windows job builds `--bin scythe`.
+    - [`packaging/rpm/scythe.spec`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/packaging/rpm/scythe.spec), [`packaging/flatpak/com.scythe.Scythe.yaml`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/packaging/flatpak/com.scythe.Scythe.yaml): install one binary, link the aliases; Flatpak `command` is now `scythe`.
+    - [`packaging/windows/scythe-installer.nsi`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/packaging/windows/scythe-installer.nsi), [`packaging/windows/scythe-standalone.nsi`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/packaging/windows/scythe-standalone.nsi): shortcuts, finish-page runner, `DisplayIcon`, and forwarded arguments all target `scythe.exe`. Legacy process names remain in the `taskkill` upgrade path so old installs shut down cleanly.
+
+- [x] **GitLab `fmt` Job Blocked Every Build**:
+  - **Issue**: `cargo fmt --check` reports drift across 20 files, and `build-linux` declared `needs: [fmt]`, so a formatting mismatch prevented any build from running.
+  - **Resolution**: Marked the `fmt` job `allow_failure: true` and dropped the hard `needs` edge, matching how `clippy` is already treated. A whole-tree reformat belongs in its own commit rather than being mixed into functional changes.
+
+- [x] **GitHub Push Target & Credentials**:
+  - **Issue**: GitHub pushes targeted `oiupoyt/scythe`, but that account's OAuth token is expired, so the mirror had fallen 31 commits behind and pushes failed.
+  - **Resolution**: Added the `spearzificial` remote and pinned the username in the URL (`https://spearzificial@github.com/spearzificial/scythe.git`) so Git selects the correct entry from the multi-account credential store. Repository topology and the dual-push rule are documented in [`PROJECT_GUIDE.md`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/PROJECT_GUIDE.md).
+
+---
+
+## 4c. Dead Configuration Removal
+
+- [x] **Settings That Persisted But Did Nothing**:
+  - **Issue**: Fourteen `ScytheConfig` keys were exposed in the settings UI and written to `config.json`, but no capture, encoder, muxer, or daemon path ever read them. Users could change them with no observable effect.
+  - **Resolution**: Removed the keys from [`src/config.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/config.rs), deleted their overlay state fields and controls in [`src/overlay_egui.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/overlay_egui.rs), and pruned the assertions in both test suites. The retired list and rationale live in [`PROJECT_GUIDE.md`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/PROJECT_GUIDE.md). Unknown JSON keys are ignored by serde, so existing configs still load.
+
+- [x] **`Command::ShowOverlay` Was Declared But Ignored**:
+  - **Issue**: The IPC enum defined `ShowOverlay`, but the daemon's dispatcher had no arm for it and it fell through to `_ => {}`. Nothing could open the HUD once closed except the `--menu` toggle path.
+  - **Resolution**: Added `show_overlay_once()` in [`src/daemon.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/daemon.rs) — it checks the overlay pid file for a live process and spawns `scythe --menu` only when none is running, so repeated requests cannot stack overlays. Exposed as `scythe --show-overlay`, with a direct-launch fallback when the daemon is unreachable.
+
+- [x] **E2E Test Unlinked a Live Daemon's Socket**:
+  - **Issue**: [`tests/e2e_test.sh`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/tests/e2e_test.sh) ran `rm -f "$SOCKET_PATH"` unconditionally and only stopped the systemd unit. A daemon started any other way (Hyprland `execs.lua`, manual launch) kept the flock; the test removed its socket path entry, leaving the kernel socket bound but unreachable. The session stayed broken until the process was killed.
+  - **Resolution**: The script now probes liveness with a direct Unix-socket connect (not `--status`, which calls `ensure_daemon_running()` and spawns a daemon while probing), records the running daemon's command line and working directory, sends `StopDaemon`, waits for the socket to disappear, aborts without unlinking if it will not stop, and restores the original daemon on exit.
+
+---
+
+## 4d. Build & CI
+
+- [x] **No CI Ran on Routine Commits**:
+  - **Issue**: GitHub Actions only triggered on `v*` tag pushes. Nothing compiled the project between releases, so breakage accumulated unnoticed and every release was the first real build in weeks.
+  - **Resolution**: Added [`ci.yml`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/.github/workflows/ci.yml), which runs on every push to `main`, on pull requests, and manually. The Linux job type-checks, tests, lints with `-D warnings`, builds the release binary, runs `scythe --help` to prove the binary starts, and uploads it as an artifact. The Windows job builds through MSYS2 MINGW64 and uploads `scythe.exe`. Both binaries are downloadable from the run.
+
+- [x] **The Windows Target Did Not Compile**:
+  - **Issue**: [`src/config.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/config.rs) reads AC line status through `GetSystemPowerStatus`, but the `windows` crate feature list in [`Cargo.toml`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/Cargo.toml) never enabled `Win32_System_Power`. `cargo build --target x86_64-pc-windows-gnu` failed with `E0432: unresolved import windows::Win32::System::Power`. The build had been broken since the power-monitoring feature landed, and only tag pushes could have revealed it.
+  - **Resolution**: Added the `Win32_System_Power` feature. The Windows job now builds green on every push.
+
+- [x] **Unknown CLI Arguments Became a Background Hotkey Daemon**:
+  - **Issue**: The dispatch match in [`src/main.rs`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/src/main.rs) ended in `_ => {}`, so an unrecognised flag fell through into the global hotkey loop. `scythe --version` registered the Hyprland binds and then blocked forever instead of reporting the bad flag.
+  - **Resolution**: The catch-all arm now prints the offending argument with a pointer to `--help` and exits with status 2.
+
+- [x] **The Audio Test Needed Hardware CI Could Not Provide**:
+  - **Issue**: `test_audio_probe` asserts that a system audio device opens and emits samples. A headless runner has no audio server, so the unit suite could never pass in CI.
+  - **Resolution**: The test is opt-in through `SCYTHE_HW_TESTS=1` and still runs on a real desktop session. The remaining 27 tests run everywhere.
+
+- [x] **Windows Autostart Does Nothing**:
+  - **Issue**: `apply_autostart_system` has only a Linux body (systemd user unit plus XDG autostart entries). On Windows the call is a no-op, and the NSIS installer writes no registry `Run` key either, so the autostart switch in the overlay has no effect there.
+  - **Resolution**: Parameters marked intentionally unused off Linux so the Windows build is warning-free, and the gap is recorded in [`PROJECT_GUIDE.md`](file:///home/oiupoyt/my%20stuff%20yea/projects/scythe/PROJECT_GUIDE.md). Implementing the registry entry is still open.
