Claude 89c63891fa chore: rebrand from Kon/Corbie to Magnotia
Replace all instances of the legacy product names "Kon" and "Corbie" with
"Magnotia" across user-facing copy, code identifiers, package names, bundle
ids, file paths, and documentation. Preserves the unrelated "konsole" (KDE
terminal) reference and the parent CORBEL company name.

- Renames 10 Rust crates (kon-* → magnotia-*) and the tauri binary
- Updates package.json, tauri.conf.json (productName + identifier)
- Renames CSS classes (kon-rh-* → magnotia-rh-*) and animations
- Renames brand and roadmap docs
- Regenerates Cargo.lock and package-lock.json

Verified: svelte-check passes; pure-rust crates compile under new names.

# Magnotia — Developer Setup
Last updated: 2026/04/18. Primary dev target: Fedora 43, x86_64, KDE Wayland, NVIDIA RTX 4070.
---
## System dependencies
### Required (CPU build)
```bash
sudo dnf install cmake clang-devel
```
| Package | Why |
|---|---|
| `cmake` | whisper-rs-sys build system |
| `clang-devel` | bindgen header generation for whisper-rs-sys |
**Fedora-specific:** `libclang.so` lives in `/usr/lib64/llvm21/lib64/`, not on the standard search path. Set permanently:
```bash
set -Ux LIBCLANG_PATH /usr/lib64/llvm21/lib64
```
Or prefix every build command:
```bash
LIBCLANG_PATH=/usr/lib64/llvm21/lib64 npm run tauri dev
```
### Required (Vulkan GPU build)
```bash
sudo dnf install vulkan-headers vulkan-loader-devel glslc
```
| Package | Why |
|---|---|
| `vulkan-headers` | `vulkan.h` needed by ggml-vulkan CMake |
| `vulkan-loader-devel` | `libvulkan.so` link target for CMake |
| `glslc` | Compiles GLSL compute shaders to SPIR-V at build time |
The NVIDIA Vulkan ICD (`nvidia_icd.json`) is included in the standard NVIDIA driver package — no extra install needed if the driver is already installed.
---
## Node / Rust
```bash
npm install # frontend deps — run once after clone
```
Rust toolchain managed by `rustup`. No extra steps needed beyond what Tauri requires.
---
## Launch commands
### CPU build (default)
```bash
cd /home/jake/Documents/CORBEL-Projects/magnotia
LIBCLANG_PATH=/usr/lib64/llvm21/lib64 npm run tauri dev
```
Once `set -Ux LIBCLANG_PATH` is in fish config, this becomes:
```bash
npm run tauri dev
```
### Vulkan GPU build
Same command — the `whisper-vulkan` feature flag is already set in `crates/transcription/Cargo.toml`. First build compiles Vulkan compute shaders and takes longer than usual.
Confirm GPU is active in startup logs:
```
whisper_backend_init_gpu: device 0: NVIDIA GeForce RTX 4070 ← GPU active
```
vs CPU fallback:
```
whisper_backend_init_gpu: device 0: CPU (type: 0) ← no GPU
```
---
## Startup log reference
Normal startup sequence:
```
[startup] Wayland workaround: GDK_BACKEND=x11
[startup] DB init: ~4ms
[startup] Preferences load: ~200µs
[startup] Whisper model pre-warmed successfully
```
The Wayland workarounds are injected automatically by `ensure_x11_on_wayland()` in `src-tauri/src/lib.rs` — no manual env-var prefix needed.
---
## Known build gotchas
| Issue | Cause | Fix |
|---|---|---|
| `Unable to find libclang` | Fedora puts clang libs in versioned path | `set -Ux LIBCLANG_PATH /usr/lib64/llvm21/lib64` |
| `Could NOT find Vulkan (missing: glslc)` | Shader compiler not installed | `sudo dnf install vulkan-headers vulkan-loader-devel glslc` |
| `there is no reactor running` | `tokio::spawn` called before runtime starts in `setup()` | Use `tauri::async_runtime::spawn` instead |
| `effect_update_depth_exceeded` | Svelte 5 `$state` object reassigned instead of mutated | Use `Object.assign(state, updates)` — never spread-replace module-level state |

## GPU notes
- **Vulkan** is the GPU backend used here. CUDA is not required.
- `crates/transcription/Cargo.toml` feature: `whisper-vulkan``whisper-rs/vulkan``ggml-vulkan`
- CPU and GPU builds are otherwise identical — same binary, same model files.
- Expected speedup on RTX 4070: ~1015× over CPU for `whisper-base.en`.
