fix: enable core library desugaring for flutter_local_notifications

flutter_local_notifications requires isCoreLibraryDesugaringEnabled and
the desugar_jdk_libs dependency to build on API < 26.  Without this the
release AAB build fails with ':app:checkReleaseAarMetadata'.

 # SharedInbox — Development Guide
 
-## Codeberg
-
-We use Codeberg: https://codeberg.org/guettli/sharedinbox/
-
-CLI tool `fgj` is available to query issues/PRs/actions.
-
-## Issue Label Workflow
-
-We use issues, follow this label state machine:
-
-- **State/ToPlan** — Issue needs a plan written by an agent before implementation
-- **State/Planned** — Plan has been posted as a comment; awaiting human review
-- **State/Ready** — Issue is approved and ready for implementation
-- **State/InProgress** — Set while an agent (or human) is actively working
-- **State/Question** — Agent hit a blocker or needs clarification
-
-Full lifecycle:
-
-```
-State/ToPlan → State/Planned   (automated: agent_loop.py runs a planning agent)
-State/Planned → State/Ready    (manual: human reviews the plan and approves)
-State/Ready → State/InProgress (automated: agent_loop.py before starting implementation)
-State/InProgress → closed      (automated: after PR is merged and CI passes)
-any state → State/Question     (automated or manual: when blocked)
-```
-
-List open issues ready to pick up:
-
-```bash
-fgj issue list --json --state open | jq '[.[] | select(.labels[].name == "State/Ready")] | .[] | {number, title, html_url}'
-```
-
-Rules:
-
-- Never start implementation on an issue without `State/Ready`
-- Planning agents only post a plan comment — they do NOT write code or open PRs
-- After `State/Planned`, a human must review the plan and manually add `State/Ready`
-- When working via the agent loop: label transitions are set automatically
-  by `agent_loop.py` — do **not** set them yourself.
-- When working manually: switch to `State/InProgress` as your **first action**:
-  ```bash
-  fgj issue edit <NUMBER> --remove-label "State/Ready" --add-label "State/InProgress"
-  ```
-- If blocked, replace current state label with `State/Question` and leave a comment explaining the blocker
-- When done and CI is green, close the issue:
-  ```bash
-  fgj issue close <NUMBER>
-  ```
-
 ## Code conventions
 
 - Avoid `else`, use "early return".

-# Dagger CI/CD Setup
-
-This project has migrated from Taskfile-based CI to **Dagger**. This document explains the infrastructure setup for the shared Dagger Server.
-
-## Architecture
-
-We use a **Shared Dagger Server** approach for both local development and CI. This allows multiple users to share a single Dagger Engine and its cache, significantly speeding up builds.
-
-- **Container Engine:** Rootless Podman (managed by the `dagger-svc` user).
-- **Orchestration:** System-wide `systemd` service.
-- **Access:** Users connect via TCP (localhost) or Unix Socket.
-
-## Server Setup (Admin)
-
-### 1. Dedicated Service User
-A dedicated user `dagger-svc` owns the Dagger Engine and its cache.
-
-```bash
-sudo useradd -m -s /bin/bash dagger-svc
-sudo loginctl enable-linger dagger-svc
-```
-
-**Why Lingering?**
-Lingering is required for rootless users to maintain a persistent background session. It ensures that `/run/user/<UID>` and the user-level Dagger/Podman namespaces are initialized at boot and remain active even when the user is not logged in.
-
-### 2. Systemd Service
-The engine is managed by a system-wide systemd service located at `/etc/systemd/system/dagger-engine.service`.
-
-```ini
-[Unit]
-Description=Dagger Engine (Shared Server)
-After=network.target
-
-[Service]
-Type=simple
-User=dagger-svc
-Group=dagger-svc
-WorkingDirectory=/home/dagger-svc
-# Replace 1003 with the actual UID of dagger-svc
-Environment=DOCKER_HOST=unix:///run/user/1003/podman/podman.sock
-Environment=XDG_RUNTIME_DIR=/run/user/1003
-ExecStart=/usr/bin/nix run github:dagger/nix/v0.11.4#dagger -- engine --addr tcp://0.0.0.0:8080
-Restart=always
-
-[Install]
-WantedBy=multi-user.target
-```
-
-## Client Configuration
-
-To connect to the shared engine, users should set the `_DAGGER_RUNNER_HOST` environment variable.
-
-### Local Development (.env)
-The project uses a `.env` file to manage the connection string. Ensure your `.env` contains:
-
-```bash
-_DAGGER_RUNNER_HOST=tcp://127.0.0.1:8080
-```
-
-### Usage
-Once the environment is set up, you can run the Dagger pipeline. For non-interactive environments (CI, LLMs), use `--progress=plain` for readable logs:
-
-```bash
-nix develop --command dagger call --progress=plain -q -m ci --source=. check
-```
-
-## Secrets
-
-All sensitive credentials are passed as `dagger.Secret` (never as plain strings).
-This prevents values from appearing in Dagger logs or being cached in the engine.
-
-| Parameter | Functions |
-|---|---|
-| `sshKey *dagger.Secret` | `Deployer`, `GenerateBuildHistory`, `BuildWebsite`, `PublishWebsite`, `DeployLinux`, `DeployApk` |
-| `keystoreBase64 *dagger.Secret` | `setupKeystore`, `BuildAndroidApk`, `DeployApk`, `SignAndroidBundle`, `PublishAndroid` |
-| `keystorePassword *dagger.Secret` | same as above |
-| `playStoreConfig *dagger.Secret` | `UploadToPlayStore`, `PublishAndroid` |
-| `serviceAccountKey *dagger.Secret` | `TestAndroidFirebase` |
-
-Secrets are injected via `WithMountedSecret` (file-based, e.g. SSH key) or
-`WithSecretVariable` (env-var-based, e.g. keystore data, Play Store JSON).
-
-The only credentials not typed as `dagger.Secret` are the test passwords
-(`STALWART_PASS_B`, `STALWART_PASS_C`) in `WithStalwart`. These are hardcoded
-development values defined in `stalwart-dev/` — not production secrets.
-
-## CI Integration (Codeberg/Forgejo)
-
-The CI workflow in `.forgejo/workflows/ci.yml` is configured to use the Dagger module located in the `ci/` directory.
-
-- **Check Suite:** Runs analysis and tests in parallel.
-- **Builds:** Produces Linux and Android artifacts.
-- **Caching:** When using the shared engine, CI runners benefit from the persistent cache on the host.
-
-## Credential Security — Keeping Production Secrets Off Codeberg
-
-### Problem
-
-The current setup stores two categories of secrets in Codeberg repository secrets:
-
-1. **Dagger access credentials** — TLS certificates used to connect to the remote Dagger engine via stunnel (`DAGGER_CA_CERT`, `DAGGER_CLIENT_CERT`, `DAGGER_CLIENT_KEY`, `DAGGER_STUNNEL_URL`).
-2. **Production secrets** — actual credentials for external services: `ANDROID_KEYSTORE_BASE64`, `ANDROID_KEYSTORE_PASSWORD`, `PLAY_STORE_CONFIG_JSON`, `SSH_PRIVATE_KEY`, `FIREBASE_TEST_LAB_SERVICE_ACCOUNT_KEY`.
-
-If Codeberg is compromised, both categories are leaked. The Dagger TLS certificates enable access only to the Dagger engine and have limited blast radius. But the production secrets give direct access to the Play Store, the Android signing key, the deployment server, and Firebase — a much larger blast radius.
-
-**Goal:** Keep only Dagger access credentials in Codeberg. Store all production secrets on the Dagger host machine so they never touch Codeberg.
-
-### Option 1: Runner-level environment variables
-
-Store production secrets as environment variables in the Forgejo runner's systemd service (e.g., via a `EnvironmentFile=` in the service override). The runner injects host env vars into job processes automatically. CI workflows drop the `${{ secrets.XYZ }}` references for production secrets entirely — the variables are already present in the job environment.
-
-**Pro:**
-- No new infrastructure required.
-- Works with the existing `dagger call --progress=plain --secret env:VAR_NAME` argument style.
-- Secrets never enter Codeberg.
-- Straightforward to set up on a single self-hosted runner.
-
-**Con:**
-- Env vars are visible to every process on the runner host (e.g., via `/proc/<pid>/environ`).
-- Rotating a secret requires host access (no API).
-- Does not scale cleanly to multiple runners without a shared secrets mechanism.
-
-### Option 2: Secret files on the CI host with restricted permissions
-
-Store production secrets as files owned by the runner user with mode `600` (e.g., `/home/forgejo-runner/secrets/play_store.json`). A small setup script reads the files and either exports them as env vars or passes them directly as file-type arguments to `dagger call --progress=plain`. CI workflows contain no secret references at all.
-
-**Pro:**
-- OS-level file permissions limit access to the runner user.
-- Natural format for JSON payloads and key files.
-- Easy to audit (list files, check mtime).
-- No new infrastructure.
-
-**Con:**
-- Plaintext files on disk; root or backup access exposes them.
-- Workflow must know file paths (either hardcoded or by convention).
-- Rotation still requires host filesystem access.
-
-### Option 3: Dagger host as pipeline orchestrator
-
-Instead of the CI runner invoking the Dagger CLI directly, the CI job sends a trigger to the Dagger host over SSH. The Dagger host runs the pipeline locally against its own environment, where secrets live as env vars or files. Codeberg only stores the SSH key to reach the Dagger host — not the production secrets.
-
-```yaml
-# CI job only does this:
-- name: Trigger pipeline on Dagger host
-  run: ssh dagger-host "cd sharedinbox && task publish-android"
-  env:
-    SSH_PRIVATE_KEY: ${{ secrets.DAGGER_TRIGGER_SSH_KEY }}
-```
-
-**Pro:**
-- Production secrets never leave the Dagger host.
-- Codeberg stores exactly one secret: the trigger SSH key.
-- All deployment logic and secrets are fully contained on the host.
-
-**Con:**
-- Harder to stream structured CI logs back to Codeberg Actions.
-- Dynamic context (commit SHA, PR branch) must be passed explicitly over SSH.
-- The trigger SSH key still grants shell access to the host, so its compromise has its own blast radius.
-- CI becomes a "fire-and-forget" call, making failure attribution harder.
-
-### Option 4: External secret manager (e.g., HashiCorp Vault)
-
-Run a secret manager co-located with the Dagger host. The CI job authenticates with a short-lived AppRole credential (stored in Codeberg) and retrieves secrets at runtime. Vault can also be configured with IP-allow-lists to further restrict who can authenticate.
-
-**Pro:**
-- Full audit trail: every secret read is logged with a timestamp and caller identity.
-- Fine-grained access control per secret.
-- Built-in versioning and rotation support.
-- Industry-standard approach; scales to team or multi-runner setups.
-
-**Con:**
-- Significant additional infrastructure to install, configure, and maintain.
-- Vault credentials (RoleID + SecretID) still need to be in Codeberg, though with a smaller blast radius than raw secrets.
-- Vault itself becomes a security-critical single point of failure.
-- Operational overhead likely disproportionate for a small single-developer project.
-
-### Recommendation
-
-**Option 1** (runner-level env vars) or **Option 2** (secret files) are the pragmatic starting point for a single self-hosted runner. They require no new infrastructure and move all production secrets off Codeberg immediately.
-
-**Option 3** (Dagger host as orchestrator) is worth considering once the trigger SSH key replaces all other secrets in Codeberg — it offers the cleanest security boundary at the cost of reduced CI observability.
-
-**Option 4** (Vault) becomes worthwhile if the project grows to multiple runners or team members who each need audited access to deploy credentials.

-# Development Environment Setup
-
-This document explains how to set up a development environment for SharedInbox.
-
-## ⚠️ Security Recommendation: Use a Dedicated Linux User
-
-For enhanced security, especially when working with autonomous coding agents (like Gemini CLI in YOLO mode), we **strongly recommend** using a dedicated Linux user for this project. This isolates the project environment and prevents any potential accidental damage to your main system.
-
-### 1. Create a Dedicated User
-
-Set the user name variable (default is `si` for SharedInbox):
-
-```bash
-export DEV_USER=si
-```
-
-Create the user and add them to the `sudo` group:
-
-```bash
-sudo adduser --disabled-password newuser $DEV_USER
-```
-
-Set up SSH public key login (replace with your actual public key):
-
-```bash
-sudo mkdir -p /home/$DEV_USER/.ssh
-sudo chmod 700 /home/$DEV_USER/.ssh
-echo "ssh-ed25519 AAAA... your-key-comment" | sudo tee /home/$DEV_USER/.ssh/authorized_keys
-sudo chmod 600 /home/$DEV_USER/.ssh/authorized_keys
-sudo chown -R $DEV_USER:$DEV_USER /home/$DEV_USER/.ssh
-```
-
-### 2. Switch to the Dedicated User
-
-```bash
-ssh $DEV_USER@localhost
-```
-
-### Create ssh-keypair
-
-```bash
-ssh-keygen
-```
-
-### 3. Clone the Repository
-
-Clone the project into your new user's home directory:
-
-```bash^
-git clone ssh://git@codeberg.org/guettli/sharedinbox.git
-
-# Move git directory into $HOME
-# This user only works on the git repo. Avoid "cd sharedinbox" after each login...
-mv sharedinbox/* .
-mv sharedinbox/.??* .
-rmdir sharedinbox/
-```
-
-### 3b. Configure Git Identity
-
-The new user needs a Git identity for commits and some scripts:
-
-```bash
-git config --global user.name "Your Name"
-git config --global user.email "your.email@example.com"
-```
-
-### 4. Install System Dependencies
-
-This project uses **Nix** with flakes to manage its toolchain (Flutter, Dart, Stalwart, etc.).
-
-```
-mkdir -p .config/nix
-
-echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf
-
-nix profile add nixpkgs#direnv
-
-nix profile add nixpkgs#nix-direnv
-
-echo 'eval "$(direnv hook bash)"' >> ~/.bashrc
-source ~/.bashrc
-
-.config/direnv/direnv.toml
-```
-[global]
-hide_env_diff = true
-#log_filter = "^$"
-
-[whitelist]
-   prefix = [ "/home/DEV_USER-CHANGE_THAT" ]
-```
-
-
-
-    ### 4b. Additional Permissions (GUI & Android)
-
-    1.  **GUI Access**: To run the Linux app (`task run`) from the `si` user, you must allow it to access your X server. Run this **from your main user terminal**:
-        ```bash
-        xhost +local:$DEV_USER
-        ```
-
-    2.  **Android Emulator (KVM)**: If you plan to use the Android emulator, add the user to the `kvm` group:
-        ```bash
-        sudo usermod -aG kvm $DEV_USER
-        ```
-
-    ### 5. Project Setup
-
-    Once you are in the project directory and have the dependencies installed:
-
-    1.  **Initialize Environment**:
-        ```bash
-        cp .env.example .env
-        ```
-
-    2.  **Allow direnv**:
-        ```bash
-        direnv allow
-        ```
-        *This will trigger Nix to download and set up the environment (Flutter, Android SDK, etc.). It might take some time on the first run.*
-
-    3.  **Install Flutter (via FVM)**:
-        Nix provides FVM, which manages the pinned Flutter version.
-        ```bash
-        fvm install
-        ```
-
-    4.  **Initial Setup**:
-        Run the comprehensive setup command which handles `pub get`, code generation, and git hooks:
-        ```bash
-        task setup
-        ```
-
-### 6. Verify the Setup
-
-Run the full check suite to ensure everything is working correctly:
-
-```bash
-task check
-```
-
-### 7. Running the App
-
-To run the app on your Linux desktop:
-
-```bash
-task run
-```
-
----
-
-## Working with VS Code
-
-To maintain isolation, it is recommended to run VS Code "remotely" on the dedicated development user.
-
-### Preferred Method: VS Code Remote - SSH
-
-The most robust way to work with a separate user is using the **VS Code Remote - SSH** extension. This allows you to run the VS Code Server as the `si` user while using your main user's GUI.
-
-1.  **Install the Extension**: Install "Remote - SSH" from the VS Code Marketplace.
-2.  **Enable SSH for the Dev User**:
-    From your main user, copy your SSH public key to the dev user:
-    ```bash
-    # As your main user:
-    sudo mkdir -p /home/$DEV_USER/.ssh
-    sudo cp ~/.ssh/id_rsa.pub /home/$DEV_USER/.ssh/authorized_keys
-    sudo chown -R $DEV_USER:$DEV_USER /home/$DEV_USER/.ssh
-    sudo chmod 700 /home/$DEV_USER/.ssh
-    sudo chmod 600 /home/$DEV_USER/.ssh/authorized_keys
-    ```
-3.  **Connect**:
-    In VS Code, open the Command Palette (`Ctrl+Shift+P`) and select `Remote-SSH: Connect to Host...`.
-    Enter: `si@localhost` (or `$DEV_USER@localhost`).
-4.  **Install Extensions in the Remote**:
-    Once connected, you will need to install the following extensions *on the remote user*:
-    *   **Dart** / **Flutter**
-    *   **direnv**: (by mkhl) Highly recommended to automatically load the Nix environment inside VS Code.
-    *   **Nix IDE**: For syntax highlighting.
-
-### Why SSH?
-Using SSH to `localhost` is preferred over complex X11/Wayland permission hacks. It provides a clean boundary for the VS Code process and any integrated terminal or coding agents, ensuring they cannot access your personal files in `/home/$YOUR_USER`.
-
-> **Note on Security:** While these instructions add the user to the `sudo` group for convenience during setup, you can remove it later with `sudo gpasswd -d $DEV_USER sudo` to further restrict the user and any coding agents.

-# Implementation Plan: Secure WebView for HTML Emails (#21)
-
-## Goal
-Replace the current `flutter_html` based rendering with a hardened WebView-based approach to improve rendering fidelity while strictly enforcing security and privacy.
-
-## 1. Dependency Management
-- **Core**: `webview_flutter` (v4+)
-- **Linux Platform**: `webview_flutter_linux` (Official community-supported or WebKitGTK based implementation). *Note: I will verify the exact package name during implementation.*
-- **Utilities**: `url_launcher` (existing) for opening links in the system browser.
-
-## 2. Secure WebView Component (`lib/ui/widgets/secure_email_webview.dart`)
-Create a new widget `SecureEmailWebView` that encapsulates the `WebViewWidget` and its controller.
-
-### Configuration & Hardening
-- **Disable JavaScript**: `controller.setJavaScriptMode(JavaScriptMode.disabled)`.
-- **Background**: Match the application theme (e.g., transparent or surface color).
-- **Security Headers/CSP**: Inject a Content Security Policy via `<meta>` tag in the HTML wrapper:
-  - `default-src 'none'; style-src 'unsafe-inline'; img-src 'self' data:;` (Blocks all external assets by default).
-
-### Image Blocking Logic
-- **Initial State**: Block remote images by injecting a CSP that restricts `img-src` to `data:` and local schemes.
-- **Toggle Mechanism**:
-  - Provide a "Load Remote Images" button in the Flutter UI.
-  - When triggered, re-render the HTML with an updated CSP: `img-src * data:;`.
-
-### Link Interception & Phishing Protection
-- Implement `NavigationDelegate.onNavigationRequest`.
-- **Process**:
-  1. Intercept any URL that doesn't start with `about:blank` or `data:`.
-  2. Block the navigation in the WebView.
-  3. Trigger a Flutter `showDialog` for confirmation.
-- **Phishing Protection Dialog**:
-  - Show the full URL.
-  - **Bold the FQDN**: Parse the URL using `Uri.parse`.
-    - Example: `https://`**`important-bank.com`**`/login`
-  - "Open in Browser" button uses `url_launcher`.
-
-## 3. Integration Plan
-### Step 1: Initialization
-Modify `lib/main.dart` to initialize the Linux WebView platform (using `webview_flutter_linux` or similar) during app startup.
-
-### Step 2: Replace Renderer in Screens
-- **EmailDetailScreen**: Replace `Html(...)` with `SecureEmailWebView(html: body.htmlBody!)`.
-- **ThreadDetailScreen**: Replace `Html(...)` with `SecureEmailWebView(html: body.htmlBody!)`.
-- Remove `flutter_html` imports and dependencies once migration is complete.
-
-## 4. Verification & Security Audit
-- **Manual Tests**:
-  - Open emails with complex HTML layouts.
-  - Verify images are blocked initially.
-  - Verify "Load images" works.
-  - Click various links (http, https, mailto) and verify the confirmation dialog and FQDN bolding.
-- **Security Check**:
-  - Verify that `<script>` tags are not executed.
-  - Verify no network requests for external images occur before user consent (via DevTools or proxy).
-
-## 5. Potential Challenges
-- **Linux WebView Stability**: WebKitGTK on Linux can sometimes have rendering or sizing issues in Flutter.
-- **Scrolling**: Ensuring the WebView integrates smoothly into the `ListView` of the email detail screen (might require fixed height or `SizedBox`).

-# Email Sync Architecture
-
-This document describes the full lifecycle of an email action — from the moment the user taps
-a button to server confirmation — covering the IMAP IDLE loop, JMAP push/poll, the pending-change
-queue, exponential backoff, and the undo/cancel mechanism.
-
-For the database schema and protocol-level implementation details see [DB-SYNC.md](DB-SYNC.md).

-## 1. Components
-
-| Component | File | Role |
-|-----------|------|------|
-| `AccountSyncManager` | `lib/core/sync/account_sync_manager.dart` | Owns one `_SyncLoop` per account; starts, stops, and wakes sync loops |
-| `_AccountSync` | same file | IMAP sync loop (IDLE + incremental fetch) |
-| `_JmapAccountSync` | same file | JMAP sync loop (SSE push + poll fallback) |
-| `EmailRepositoryImpl` | `lib/data/repositories/email_repository_impl.dart` | All DB reads/writes and network calls |
-| `pending_changes` table | `lib/data/db/database.dart` | Protocol-agnostic outbound mutation queue |
-| `UndoService` | `lib/core/services/undo_service.dart` | Persisted undo history; cancel-or-reverse logic |

-## 2. Lifecycle of an email mutation (e.g. "Mark as read")
-
-```
-User taps "Mark as read"
-        │
-        ▼
-EmailRepository.setFlag(id, seen: true)
-        │
-        ├─ 1. Write optimistic update to local DB
-        │      emails.is_seen = true
-        │
-        └─ 2. Insert row into pending_changes
-               { type: 'flag_seen', email_id: id, payload: {seen: true} }
-               (IMAP: includes uid + mailboxPath for the STORE command)
-               (JMAP: includes just the flag map for Email/set)
-
-[UI immediately reflects the change via Drift's reactive streams]
-
-        │
-        ▼ (next sync cycle, triggered by IMAP IDLE / JMAP push / wakeUp)
-_SyncLoop._flush() / flushPendingChanges()
-        │
-        ├─ IMAP: open connection → STORE uid +FLAGS (\Seen) → close
-        │
-        └─ JMAP: Email/set { update: { id: { keywords: { "$seen": true } } } }
-               If stateMismatch → clear checkpoint → full re-sync
-
-        │
-        ▼
-pending_changes row deleted on success
-(on permanent error: retry count incremented; evicted after 5 failures)
-```
-
----
-
-## 3. IMAP sync loop
-
-The IMAP loop runs one coroutine per account (`_AccountSync`):
-
-```
-start()
-  │
-  ▼
-[forever loop]
-  ├─ flushPendingChanges()   ← drain outbound queue first
-  ├─ syncMailboxes()         ← detect new/removed mailboxes
-  ├─ for each mailbox:
-  │    syncEmails()          ← incremental: fetch only UIDs > lastUid
-  │                             deletion reconciliation: remove rows
-  │                             whose UID is absent from the server
-  └─ _idle()                 ← IMAP IDLE for up to 25 min (RFC 2177)
-       │                        Wakes on: server EXISTS/EXPUNGE/FLAGS
-       │                        or syncNow() signal from UI
-       └─ repeat
-```
-
-**Incremental sync checkpoint** — `sync_state` table stores `(accountId, mailbox, lastUid, uidValidity)`.
-On each run, only UIDs greater than `lastUid` are fetched. If `uidValidity` changes the full
-folder is re-scanned and the checkpoint is reset.
-
-**IDLE cap** — IDLE sessions are limited to 25 minutes per the RFC. The loop also wakes
-immediately if `syncNow()` is called (e.g. user pulls-to-refresh).
-
----
-
-## 4. JMAP sync loop
-
-The JMAP loop (`_JmapAccountSync`) follows a similar structure but uses HTTP:
-
-```
-start()
-  │
-  ▼
-[forever loop]
-  ├─ flushPendingChanges()   ← Email/set for queued mutations
-  ├─ syncMailboxes()         ← Mailbox/get or Mailbox/changes
-  ├─ for each mailbox:
-  │    syncEmails()          ← Email/query + Email/get (first run)
-  │                             Email/changes (subsequent runs, state token)
-  └─ _wait()
-       ├─ If server advertises eventSourceUrl: subscribe to SSE push
-       │    wake on "Email" change event
-       └─ Otherwise: sleep 30 s (poll fallback)
-```
-
-**State tokens** — each `Mailbox/changes` / `Email/changes` call uses the server-provided
-`state` token stored in `sync_state`. A `stateMismatch` error clears the token and triggers
-a full re-fetch.
-
-**JMAP send** — outgoing mail uses `EmailSubmission/set` when the server advertises the
-`urn:ietf:params:jmap:submission` capability; falls back to SMTP otherwise.
-
----
-
-## 5. Exponential backoff
-
-Both loops share the same backoff policy:
-
-| Outcome | Backoff |
-|---------|---------|
-| Sync succeeded | Reset to 5 s |
-| Network / server error | Double previous backoff, capped at 900 s (15 min) |
-
-The backoff counter (`_backoffSeconds`) is per-account and per-process; it resets to 5 s
-on the next successful cycle.
-
-The last error message is written to `sync_log` and surfaced in the UI via
-`syncLastErrorProvider` (the red `MaterialBanner` in the email list).
-
----
-
-## 6. Pending-change queue
-
-`pending_changes` is a protocol-agnostic table that stores every outbound mutation before it
-reaches the server:
-
-| Column | Description |
-|--------|-------------|
-| `id` | Auto-increment primary key |
-| `email_id` | The email being mutated |
-| `type` | `flag_seen`, `flag_flagged`, `move`, `delete`, `snooze` |
-| `payload` | JSON-encoded protocol-specific arguments |
-| `retry_count` | Incremented on each failed flush attempt |
-| `created_at` | For ordering and debug |
-
-**Optimistic UI** — every mutation writes the local change first, then inserts into
-`pending_changes`. The Drift reactive stream delivers the update to the UI before
-the network round-trip completes.
-
-**Conflict resolution** — the server always wins. On the next sync cycle the server's
-state overwrites local rows. Outbound mutations are retried up to 5 times; after that
-they are evicted and a `FailedMutation` record is created. Permanent per-item JMAP
-errors (`notFound`, `forbidden`) skip the retry counter and evict immediately.
-
----
-
-## 7. Undo and cancel
-
-When the user triggers an undoable action the UI calls:
-```
-ref.read(undoServiceProvider.notifier).pushAction(UndoAction(...))
-```
-
-`UndoService` persists the action to the `undo_actions` table (max 10 entries, FIFO).
-A `SnackBar` with an **Undo** button appears for a few seconds.
-
-When the user taps Undo, `UndoService.undo()` executes this sequence for each affected email:
-
-```
-1. cancelPendingChange(id, originalType)
-      └─ Deletes the pending_changes row if it has not been flushed yet.
-         Returns true if cancelled, false if the server already processed it.
-
-2. If the email row was hard-deleted (DELETE action):
-      restoreEmails([original])
-         └─ Re-inserts the row with its pre-deletion state,
-            placed in the correct mailbox (source if cancelled, dest otherwise).
-
-3. moveEmail(id, sourceMailboxPath)
-      └─ Optimistic local move back to the original folder.
-         If step 1 returned false (already sent to server), this enqueues
-         a reverse-move in pending_changes so the server move is undone too.
-
-4. If step 1 returned true (cancelled before flush):
-      cancelPendingChange(id, 'move')
-         └─ The reverse-move from step 3 is redundant; remove it.
-```
-
-The net result is: if the mutation was still in the queue it is silently cancelled with no
-server round-trip; if it had already been flushed, a compensating move is queued.
-
----
-
-## 8. Key invariants
-
-- **Order**: pending changes are flushed before syncing. This prevents the server from
-  overwriting an optimistic local state that the server hasn't seen yet.
-- **Idempotency**: `flushPendingChanges` is safe to call multiple times. Each row is
-  deleted only after the server acknowledges the change.
-- **No silent data loss**: permanent server errors surface as `FailedMutation` records
-  visible in the UI (Settings → Failed mutations).
-- **UI layer isolation**: `lib/ui/` never imports `lib/data/`; all interaction goes
-  through `core/` interfaces. The `check-layers` Taskfile task enforces this.

-## Connecting to Dagger (via stunnel)
-
-Dagger is running on the host machine and exported via stunnel on port 8774. The runner connects to it using a local stunnel client.
-
-The following TLS secrets must be configured as environment variables in Codeberg:
-- `DAGGER_CLIENT_CERT`: Content of `client.crt`
-- `DAGGER_CLIENT_KEY`: Content of `client.key`
-- `DAGGER_CA_CERT`: Content of `ca.crt`
-
-### Setup Script
-
-This snippet can be used in a CI job to establish the connection:
-
-```bash
-# Write TLS files from environment variables
-mkdir -p /etc/dagger/tls
-echo "$DAGGER_CLIENT_CERT" > /etc/dagger/tls/client.crt
-echo "$DAGGER_CLIENT_KEY" > /etc/dagger/tls/client.key
-echo "$DAGGER_CA_CERT" > /etc/dagger/tls/ca.crt

-2. No agent running → extract pending_issue from state (if any), then check CI
-   a. pending_issue type=="plan" → post resume comment, set State/Planned, exit 0
-   b. pending_issue + open PR → check PR branch CI, merge/fix/wait as needed
-   c. Catch-up: orphaned issue-N-fix PRs with passing CI → merge them
-   d. Main CI running         → save pending-ci state, exit 0
-   e. Main CI failed          → start fix-CI agent (pushes fix to main), exit 0
-   f. Main CI ok + pending_issue → close the issue, exit 0  (dead code path —
-                                   section 2b always returns first)
-   g. Main CI ok (or no run yet) → find oldest ToPlan issue, start plan agent,
