+# Mindwtr 1.2.0-rc.2
+
+This candidate fixes data durability and recovery gaps found after rc.1. It includes Android system search, sequential-project corrections, and desktop responsiveness work merged during the test window.
+
+## Blocker fixes
+
+- Core keeps failed incremental snapshots pending and reports the save failure until a durable retry succeeds, so a stale storage read cannot replace unsaved work.
+- Mobile preserves recovery snapshots when two files would receive the same label, and first-run starter data now waits for its save to finish.
+- The self-hosted cloud server acknowledges data, attachment, and directory changes after it has synced them to disk. Retries repair interrupted directory and deletion durability work.
+- Desktop sync isolates watcher lifecycles, ignores stale callbacks, binds credentials to the selected endpoint, and verifies the SQLite database before reusing a warm connection.
+- Windows File Sync normalizes lock contention and publishes configuration changes with durable file replacement.
+
+## Changes to test
+
+- Android 12 and newer can expose task, project, and area titles to device system search through an opt-in Privacy setting. The index stays on the device and the setting starts off.
+- Sequential projects now treat a Waiting For first step as the blocker and stop a later dated task from replacing the first available action.
+- Contexts and tags entered without `@` or `#` gain the expected prefix, matching capture and autocomplete behavior.
+- Android email shares use the message subject as the task title and place the body in the description.
+- Settings separates Backup from Import Data, while search opens the matching fold.
+- Linux keeps the tray icon in the app cache so temp cleanup cannot leave an empty tray slot.
+
+## Testing focus
+
+- Upgrade from v1.1.6 or rc.1, create and edit tasks, restart the app, and confirm the changes persist.
+- Trigger a recoverable storage failure, retry the save, and confirm the app keeps the newest snapshot and recovery history.
+- Run two clients against self-hosted cloud sync, including concurrent edits and attachment deletion, then confirm a second sync produces no changes.
+- Exercise Windows File Sync on a local folder and a WinFSP or rclone mount; confirm sync settles without lock errors or UI stalls.
+- Enable Android system search, open each entity type from a result, then disable the setting and confirm Mindwtr removes its index.
+- Test a sequential project whose first step is Waiting For and another whose later step has a start date.
