chore: bump sidecar version to 1.0.15 [skip ci]

Engines now read user.name from the config object at transcription time
instead of caching it at init, so name changes take effect immediately.

+## Code Signing
+
+Code signing is configured for Windows and macOS to eliminate install warnings (SmartScreen / Gatekeeper). See [SIGNING.md](SIGNING.md) for full setup details.
+
+**Status (as of 2026-04-10):** CI workflow changes are committed. Waiting on identity verification for both platforms before secrets can be configured.
+
+**How it works:**
+- macOS: Tauri auto-signs when `APPLE_CERTIFICATE` and related env vars are set in CI. Notarization uses App Store Connect API key.
+- Windows: Azure Artifact Signing via `signtool.exe` + dlib. CI workflow injects `signCommand` into `tauri.conf.json` at build time when `AZURE_CLIENT_ID` is set.
+- Both are no-ops when secrets aren't configured — unsigned builds work as before.
+
+**Key files:**
+- `src-tauri/Entitlements.plist` — macOS hardened runtime entitlements (mic, network)
+- `src-tauri/Info.plist` — macOS microphone usage description
+- `.gitea/workflows/build-app-macos.yml` — Apple signing + notarization
+- `.gitea/workflows/build-app-windows.yml` — Azure Artifact Signing
+
+**Secrets required (12 total):** See [SIGNING.md](SIGNING.md) for the full list — 6 Apple secrets, 6 Azure secrets.

 ## Usage
 
-### Standalone Mode
+### Quick Setup (Cloud — Recommended)
 
 1. Launch the application
-2. Select your microphone from the audio device dropdown
+2. Open **Settings** — the transcription mode defaults to **Cloud (Deepgram)**
-3. Choose a Whisper model (smaller = faster, larger = more accurate):
+3. Get a free API key at [console.deepgram.com](https://console.deepgram.com) and paste it in Settings
+4. Select your microphone from the audio device dropdown
+5. Click **Start Transcription**
+6. Transcriptions appear in the main window and at `http://localhost:8080`
+
+> The Start button is disabled until an API key is entered. Local-only settings (model, VAD, timing) are hidden in cloud mode to keep things simple.
+
+### Local Mode (Whisper)
+
+For offline/on-device transcription, switch to **Local (Whisper)** in Settings:
+
+1. Choose a Whisper model (smaller = faster, larger = more accurate):
    - `tiny.en` / `tiny` — Fastest, good for quick captions
    - `base.en` / `base` — Balanced speed and accuracy
    - `small.en` / `small` — Better accuracy
    - `medium.en` / `medium` — High accuracy
    - `large-v3` — Best accuracy (requires more resources)
-4. Click **Start** to begin transcription
+2. Select compute device (Auto/CUDA/CPU) and compute type
-5. Transcriptions appear in the main window and at `http://localhost:8080`
+3. Tune VAD sensitivity and timing settings as needed
-
+4. Click **Start Transcription**
-### Remote Transcription (Deepgram)
-
-Instead of local Whisper models, you can use cloud-based transcription:
-
-- **Managed mode**: Sign up via the transcription proxy for metered billing
-- **BYOK mode**: Bring your own Deepgram API key for direct access

+# Code Signing Setup
+
+This document explains how to configure code signing for Local Transcription so that Windows and macOS installers are trusted by the operating system.
+
+## Overview
+
+Without code signing:
+- **Windows**: SmartScreen shows "Windows protected your PC" warnings
+- **macOS**: Gatekeeper blocks the app — "app can't be opened because it is from an unidentified developer"
+
+The CI/CD workflows are configured to sign automatically when the required secrets are present. Without secrets, builds still work — they just produce unsigned installers.
+
+---
+
+## Windows — Azure Artifact Signing
+
+**Cost**: ~$9.99/month (up to 5,000 signatures)
+
+### 1. Create an Azure Account
+
+Sign up at https://azure.microsoft.com if you don't already have one.
+
+### 2. Set Up Artifact Signing
+
+1. In the Azure Portal, search for **Artifact Signing**
+2. Create a new **Artifact Signing Account**
+   - Choose a region (e.g., West US 2) — note this for the endpoint URL
+   - The endpoint will be like `https://wus2.codesigning.azure.net/`
+3. Complete **Identity Verification** (required before you can create certificate profiles)
+4. Create a **Certificate Profile** with type "Public Trust" for code signing
+
+### 3. Create an App Registration (Service Principal)
+
+This allows CI to authenticate to Azure:
+
+1. Go to **Azure Active Directory** > **App registrations** > **New registration**
+2. Name it (e.g., `local-transcription-signing`)
+3. After creation, note the **Application (client) ID** and **Directory (tenant) ID**
+4. Go to **Certificates & secrets** > **New client secret** — note the secret value
+5. Grant the app registration the **Artifact Signing Certificate Profile Signer** role on your Artifact Signing Account
+
+### 4. Add Gitea Secrets
+
+In your Gitea repository, go to **Settings** > **Actions** > **Secrets** and add:
+
+| Secret Name | Value |
+|-------------|-------|
+| `AZURE_CLIENT_ID` | App registration Application (client) ID |
+| `AZURE_CLIENT_SECRET` | App registration client secret value |
+| `AZURE_TENANT_ID` | Directory (tenant) ID |
+| `AZURE_SIGNING_ENDPOINT` | Artifact Signing endpoint URL (e.g., `https://wus2.codesigning.azure.net/`) |
+| `AZURE_SIGNING_ACCOUNT` | Artifact Signing account name |
+| `AZURE_CERT_PROFILE` | Certificate profile name |
+
+---
+
+## macOS — Apple Developer Code Signing + Notarization
+
+**Cost**: $99/year (Apple Developer Program)
+
+### 1. Enroll in the Apple Developer Program
+
+Sign up at https://developer.apple.com/programs/
+
+### 2. Create a Developer ID Certificate
+
+1. Open **Xcode** > **Settings** > **Accounts** > select your team > **Manage Certificates**
+2. Click **+** > **Developer ID Application**
+3. Or create via the Apple Developer portal: **Certificates, Identifiers & Profiles** > **Certificates** > **+** > **Developer ID Application**
+
+### 3. Export the Certificate as .p12
+
+1. Open **Keychain Access**
+2. Find your **Developer ID Application** certificate
+3. Right-click > **Export** > save as `.p12` with a password
+4. Base64-encode it:
+   ```bash
+   base64 -i certificate.p12 | tr -d '\n'
+   ```
+
+### 4. Create an App Store Connect API Key
+
+This is used for notarization (submitting the app to Apple for verification):
+
+1. Go to https://appstoreconnect.apple.com/access/integrations/api
+2. Click **Generate API Key**
+3. Give it a name and **Developer** role (minimum)
+4. Download the `.p8` private key file (you can only download it once)
+5. Note the **Key ID** and **Issuer ID** shown on the page
+
+### 5. Find Your Signing Identity
+
+Your signing identity looks like:
+```
+Developer ID Application: Your Name (TEAMID)
+```
+
+You can find it by running:
+```bash
+security find-identity -v -p codesigning
+```
+
+### 6. Add Gitea Secrets
+
+| Secret Name | Value |
+|-------------|-------|
+| `APPLE_CERTIFICATE` | Base64-encoded .p12 certificate (from step 3) |
+| `APPLE_CERTIFICATE_PASSWORD` | Password used when exporting the .p12 |
+| `APPLE_SIGNING_IDENTITY` | Full identity string (e.g., `Developer ID Application: Your Name (TEAMID)`) |
+| `APPLE_API_KEY` | App Store Connect API Key ID |
+| `APPLE_API_ISSUER` | API issuer UUID |
+| `APPLE_API_KEY_CONTENT` | Full contents of the `.p8` private key file |
+
+---
+
+## Verifying Signing Works
+
+### Trigger a Build
+
+Both build workflows use `workflow_dispatch`, so you can trigger them manually in Gitea:
+
+1. Go to **Actions** > select the workflow > **Run workflow**
+2. Enter the release tag (e.g., `v2.0.15`)
+
+### Check macOS
+
+After installing the `.dmg`, the app should open without any Gatekeeper warnings. You can also verify from the command line:
+
+```bash
+codesign -dv --verbose=4 /Applications/Local\ Transcription.app
+spctl --assess --type execute /Applications/Local\ Transcription.app
+```
+
+### Check Windows
+
+After running the `.msi` or `-setup.exe`, there should be no SmartScreen warning. The installer properties should show your organization name as the publisher.
