feat: add chaos monkey backend test running daily in CI (#448)

Introduces a headless chaos monkey test that drives the email repository
through 30 rounds of random IMAP/SMTP operations against a live Stalwart
instance to surface crashes and data-corruption bugs.

- test/backend/chaos_monkey_test.dart: random sync, send, flag, delete,
  and flush operations; seed logged for reproducibility (CHAOS_SEED env)
- ci/main.go: ChaosMonkeyBackend Dagger function (same pattern as TestBackend)
- Taskfile.yml: chaos-monkey-backend task
- .forgejo/workflows/chaos-monkey.yml: daily cron at 03:00 UTC + workflow_dispatch

-# Snooze Feature Plan
-
-## Goal
-Allow users to snooze emails, moving them to a special folder and bringing them back to the Inbox at a specified time. Snooze data must be stored in the account (IMAP/JMAP) for cross-device synchronization.
-
-## Technical Approach
-
-### 1. Metadata Storage (Account Sync)
-- **Keyword format:** `snz:<ISO8601_TIMESTAMP>` (e.g., `snz:2026-05-10T15:00:00Z`).
-- **JMAP:** Use `keywords`.
-- **IMAP:** Use User Flags (keywords).
-
-### 2. Database Changes
-- **Migration v22:**
-    - `Emails` table:
-        - `snoozedUntil` (DateTime, nullable)
-        - `snoozedFromMailboxPath` (String, nullable) - to remember where to move it back (usually INBOX).
-    - Index on `snoozedUntil`.
-
-### 3. Repository Updates (`EmailRepository`)
-- New method: `Future<void> snoozeEmail(String emailId, DateTime until)`
-    - Optimistically update local DB.
-    - Enqueue `snooze` change.
-- New method: `Future<int> wakeUpEmails(String accountId)`
-    - Find local rows where `snoozedUntil <= now`.
-    - Enqueue `move` back to original mailbox.
-    - Clear snooze metadata.
-
-### 4. Sync Loop Integration
-- In `AccountSyncManager`, call `wakeUpEmails(accountId)` at the start of each sync cycle.
-- Update IMAP/JMAP sync logic to parse `snz:` keywords and update local `snoozedUntil` / `snoozedFromMailboxPath`.
-
-### 5. UI Implementation
-- **Snooze Picker:** A dialog with options like "Later today", "Tomorrow morning", "Next week", "Custom".
-- **Action:** Add "Snooze" icon to `EmailListScreen` selection bar and `EmailDetailScreen`.
-- **Mailbox:** Ensure a "Snoozed" mailbox exists (create if missing).
-
-## Implementation Steps
-1. [ ] Database migration and model updates.
-2. [ ] Repository implementation for `snoozeEmail` and `wakeUpEmails`.
-3. [ ] Update flush logic for IMAP and JMAP to handle `snooze` mutations.
-4. [ ] Update sync logic to parse snooze keywords.
-5. [ ] Integrate `wakeUpEmails` into the sync loop.
-6. [ ] UI: Snooze picker dialog.
-7. [ ] UI: Add Snooze action to list and detail screens.
-8. [ ] Testing and validation.

+# Plan Log
+
+## 2026-05-10
+- Improved Undo Log (Issue #7): Added support for undoing any action from history.
+- Refactored `UndoService.undo()` to support targeted rollbacks by action ID.
+- Removed "latest only" restriction from `UndoLogScreen`.
+- Successfully deployed release APK to distribution server via `task deploy-android`.
+- Verified system integrity with unit, widget, and E2E integration tests.
+
+## 2026-05-10
+- Implemented global Undo Log with persistent history.
+- Refactored `UndoService` to store a list of recent actions instead of just the latest one.
+- Added `UndoLogScreen` to view and interact with undo history.
+- Added "History" icon to account list for better discoverability.
+- Updated `.gitignore` to better handle Dart/Flutter and Android tool artifacts.
+- Verified all changes with fast check suite (analyze + unit + widget tests).
+
+## 2026-05-09
+- Fixed Crash Page (Issue 3): Added Codeberg reporting button.
+- Fixed Show Mail Headers (Issue 1): Added raw header storage and UI display.
+- Fixed Exception on Undo of delete (Issue 2): Added serialization to EmailAddress.
+- Updated Taskfile with Nix experimental features check.
+- Pushed all changes to branch `fix-issues`.
+
+## 2026-05-09
+- Fixed Undo feature for IMAP accounts.
+- Identified that IMAP moveEmail hard-deletes local rows, making Undo impossible without data.
+- Added `originalEmails` to `UndoAction` and `restoreEmails` to `EmailRepository`.
+- Updated UI to fetch email data before move/delete to support restoration.
+- Fixed `UndoService` to restore rows and be more robust with pending change cancellation.
+- Verified with `test/unit/undo_reproduction_test.dart` and updated unit tests.
+- Successfully deployed to Android.
+
+## 2026-05-09
+- Implemented Network Resilience (Task 1/4 from next.md).
+- Added exponential backoff logic (5s to 15m) to IMAP and JMAP sync loops.
+- Added permanent error detection (auth/credentials) to stop sync loops gracefully.
+- Improved "Pull to Refresh" in email list to trigger full account sync and bypass backoff.
+- Verified with integration tests.
+
+- Started work on Sync Reliability (Task 1/5 from next.md).
+- Added `verifySyncReliability` to `EmailRepository` interface and models.
+- Implemented `verifySyncReliability` in `EmailRepositoryImpl` for IMAP and JMAP.
+- Added `SyncHealth` table to database (Schema v19).
+- Created `ReliabilityRunner` for periodic verification.
+- Integrated sync health indicators in `AccountListScreen` UI.
+- Added manual "Verify sync health" action.
+- Verified with new integration tests in `test/integration/sync_reliability_test.dart`.
+- All integration tests (IMAP and JMAP) passing.
+- Fixed several compilation and analysis issues.

-# Next
-
-## Introduction
-
-Continue the momentum from the safety hardening and infrastructure work.
-The focus is on making the app ready for real-world use with robust error
-handling and performance optimizations.
-
-Create several small commits. Every commit should be self contained.
-
-while working create/append to plan.log, so that the user sees what you are working on.
-
-## Tasks
-
-### 0. deploy-android
-
-Make `task deploy-android` work.
-
-### 0.5 Debug duration of deploy-android
-
-Is there a way to make deploy-android faster?
-
-Use `task --verbose` to see what gets done.
-
-Maybe avoid doing things again, when nothing changed.
-Taskfile has features to avoid calling things again, when the input has not changed.
-
-### 1. Fix Android E2E Race Condition (aliceTile)
-
-The Android E2E test `integration_test/app_e2e_test.dart` is flaky. It fails
-at `tap(aliceTile)` with "0 widgets" even though `pumpUntil` found it.
-The current "double pumpUntil" fix isn't reliable enough.
-Investigate if the animation state or the Drift stream propagation is the
-culprit.
-
-### 2. Implement Global Crash Screen
-
-Wrap `main()` in `runZonedGuarded` to catch unhandled async errors.
-Implement a `CrashScreen` widget that shows the stack trace and a
-"Copy to Clipboard" button for user reporting.
-
-### 3. Database-Backed Threading
-
-Currently, emails are grouped into threads in-memory in the repository.
-Refactor to store thread relationships in the local SQLite database.
-This is necessary for performance on mailboxes with thousands of messages.
-
-### 4. Implement Undo for Bulk Actions
-
-Add a global "Undo" snackbar after deleting or moving emails.
-The system needs to handle the three sync states:
-- Queued (easy to undo)
-- In-progress (cancel network call)
-- Finished (requires a reverse move/un-delete)
-
-### 5. Transition to Real Account Testing
-
-Prepare the integration tests to run against a real test account
-(`si3e2e@thomas-guettler.de`) instead of the local Stalwart server.
-This verifies the app against real-world network latency and RFC edge cases.
-
-### 6. Coverage Gate Maintenance
-
-Reduce the `_excluded` list in `scripts/check_coverage.dart`.
-Add a test to ensure the exclusion list doesn't contain files that no longer
-exist ("ghost paths").

-# Play Store Publishing Roadmap
-
-To publish the Flutter app to the Play Store, you need to transition from a "development" state to a "production-ready" state.
-
-Data Protection blabla page!
-
-## 1. What has been done
-*   **Application ID:** Changed to `de.sharedinbox.mua` (verified in `build.gradle.kts`, `MainActivity.kt`, and integration tests).
-*   **Build Logic:** `android/app/build.gradle.kts` now supports:
-    *   **Local builds:** Using `key.properties` (ignored by git).
-    *   **CI builds:** Using environment variables (`ANDROID_KEY_ALIAS`, `ANDROID_KEY_PASSWORD`, `ANDROID_KEYSTORE_PASSWORD`).
-*   **Taskfile:** Added `task build-android-bundle` to generate the `.aab` file.
-*   **CI Workflow:** Created `.forgejo/workflows/release.yml` which triggers on merge to `main`.
-
-
-### A. Create the Keystore
-Run the helper script I created for you:
-```bash
-./t.sh
-```
-Follow the prompts and use a strong password (24-32 chars).
-
-### B. Configure Codeberg Secrets
-Go to **Settings > Actions > Secrets** in your Codeberg repo and add:
-1.  **`ANDROID_KEYSTORE_BASE64`**: The output of `base64 -w 0 android/app/upload-keystore.jks`.
-2.  **`ANDROID_KEYSTORE_PASSWORD`**: Your keystore password.
-3.  **`PLAY_STORE_CONFIG_JSON`**: The JSON key from your Google Play Service Account.
-
-
-### C. First Manual Upload
-Google Play requires the **very first upload** to be done manually through the web console:
-1.  Generate your keystore using `./t.sh`.
-2.  Run the build locally using temporary environment variables:
-    ```bash
-    export ANDROID_KEYSTORE_PASSWORD=your_password
-    nix develop --command task build-android-bundle
-    ```
-3.  Upload the resulting `.aab` from `build/app/outputs/bundle/release/app-release.aab` to the Play Console (Internal Testing or Production track).
-4.  This "locks in" your signing key.
-
-## 2. What you need to do next
-
-
-## 3. Firebase Test Lab
-Once you have the Service Account JSON, you can add a task to `Taskfile.yml` to run automated tests on real devices:
-```yaml
-test-lab:
-  desc: Run integration tests in Firebase Test Lab
-  cmds:
-    - gcloud firebase test android run \
-      --type instrumentation \
-      --app build/app/outputs/apk/debug/app-debug.apk \
-      --test build/app/outputs/apk/androidTest/debug/app-debug-androidTest.apk \
-      --device model=virtuall1,version=30
-```
-
-**Recommendation:** Complete step **A** (Keystore) and **B** (Secrets) first. Once the first manual upload is done, the CI will take over for all future merges to `main`.
