+## Data Persistence (SQLite + Backups)
+
+The app stores its SQLite database and runtime config under **`Data/`** (capital D) relative to the content root:
+
+| Path in container | Purpose |
+|-------------------|---------|
+| `/app/Data/app.db` | Live SQLite database |
+| `/app/Data/appsettings.json` | Chapter settings overrides (e.g. CompetitionYear) |
+| `/app/Data/backups/pre-rollover-*.db` | Automatic backups created by New Year Rollover |
+
+**Docker volume mount must use capital `Data`:**
+
+```yaml
+volumes:
+  - ./data:/app/Data
+```
+
+On Linux, `./data:/app/data` is a **different** path and will not persist the database or rollover backups. After a correct mount, host files appear under `./data/` (for example `./data/app.db` and `./data/backups/`).
+
+Ensure the container user can write to the mounted directory (the image runs as a non-root `APP_UID`). If directory creation for `backups/` fails, year rollover aborts before changing data.
+
+For the rollover workflow itself, see `docs/instructions/year-rollover.md`.

+# Import Student Event Rankings
+
+**Created:** 2026-08-28  
+**Last updated:** 2026-08-28  
+**Description:** How to import student event preference rankings from a CSV.
+
+## CSV format
+
+```
+Student Name,1,2,3,4,5,6
+"Last, First",Video Game Design,Coding,Flight
+First Last,Video Game,Coding
+```
+
+- `Student Name` is required. `Last, First` and `First Last` both work.
+- Rank columns are `1` through `10`. Empty cells are skipped. Extra columns are ignored.
+- Event cells may be the official name, the catalog short name, or a close miss. Fuzzy matching scores both.
+- Known nicknames that fuzzy cannot reach are also accepted, including `Solar Racer`, `Challenging Tech`, `Digital Photo`, `Forensics`, `Micro Controller`, `Med Tech`, `Innovations & Inventions`, `Systems Control Tech`, `Structural Eng`, `Drone Challenge`, `Robotics`, and `Audio Podcast`.
+
+## Steps
+
+1. Sign in and open **Student Event Ranks** (`/students/event-ranking`).
+2. Click **Import**.
+3. Choose the CSV and click **Parse**.
+4. Review matched rows (raw text, chosen event, score) and any unmatched or ambiguous issues.
+5. Click **Save to Database**. If any matched student already has rankings, confirm the replace dialog.
+
+Save replaces rankings only for students who have at least one accepted rank in the file. Other students are unchanged.
+
+## What is not imported
+
+Unmatched students, unmatched events, and ambiguous event names are reported in the preview and are not saved. Fix the CSV text or add the student/event in the app, then parse again.

+# Year Rollover Runbook
+
+**Created:** 2026-08-14  
+**Last updated:** 2026-08-28  
+**Description:** How to roll the chapter into a new competition year using the locked New Year wizard.
+
+## Prerequisites
+
+1. Confirm **School Level** is set correctly on [Chapter Settings](/settings/chapter) (`Middle School` or `High School`). That drives the graduating grade (8 or 12).
+2. Have the list of **returning students** and the **new officer slate** ready.
+3. Plan a short maintenance window: after apply you must **restart the app** so printouts pick up the new competition year.
+4. On Docker, confirm the data volume is `./data:/app/Data` (capital **D**). See `DEPLOYMENT.md` — otherwise the automatic backup may not land on the host.
+
+## Steps
+
+1. Sign in as an **Administrator**.
+2. Open **New Year Rollover** at `/settings/new-year` (Admin nav: “New Year Rollover (locked)”).
+3. **Unlock the wizard** (required every session):
+   - Check both acknowledgment boxes.
+   - Type `ROLLOVER` and click **Unlock wizard**.
+   - Refreshing or using **Lock again** re-locks it.
+4. **Step 1 — Year & grades**
+   - Confirm the target competition year (defaults to current + 1).
+   - Confirm the chapter type / graduating grade shown from Chapter Settings.
+5. **Step 2 — Returning roster**
+   - Uncheck anyone who is not returning (grade at/above graduating is unchecked by default).
+   - Optionally paste a name list (`Last, First` or `First Last`) and click **Apply pasted names**.
+6. **Step 3 — Officers**
+   - Assign each office from returning students, or leave vacant.
+   - Officers who are brand-new students can be set later on the student edit page.
+7. **Step 4 — Season reset**
+   - Teams, event rankings, and meeting history are always cleared.
+   - Leave **Clear all event occurrences** checked unless you have a reason to keep last year's calendar rows.
+8. **Step 5 — Preview & apply**
+   - Review promotions, removals, officers, and warnings.
+   - Type the target competition year exactly to enable **Apply rollover**.
+   - Confirm the destructive dialog. The wizard creates `Data/backups/pre-rollover-yyyyMMdd-HHmmss.db` first; that file is the only undo.
+9. **Restart the application** so the home page and printouts show the new competition year.
+10. **Add new students** via `/students/create` or `/import`.
+    - `/import` is add-only and skips existing first+last name matches, so re-importing a full roster is safe for returners.
+11. **Import the new state schedule** from the calendar import page.
+12. On **Meeting Schedule**, click **Reset** once. That page keeps team/student ids in browser localStorage; after a rollover those ids are stale.
+13. Collect new event rankings (CSV import at `/students/event-ranking/import`, or the ranking editor) and run team assignment as usual.
+
+## What is deleted vs kept
+
+| Cleared | Kept |
+|---------|------|
+| Non-returning students | Returning students (promoted) |
+| All teams | Event definitions (national catalog) |
+| All event rankings | Notes (including meeting notes by title) |
+| All meeting history attendance snapshots | Database backup under `Data/backups/` |
+| Event occurrences (when checked) | |
+
+## Backup location
+
+| Environment | Backup path |
+|-------------|-------------|
+| Local (`dotnet run`) | `WebApp/Data/backups/pre-rollover-*.db` |
+| Docker (with `./data:/app/Data`) | Host: `./data/backups/pre-rollover-*.db` (container: `/app/Data/backups/`) |
+
+## Restore from backup (emergency)
+
+1. Stop the application (or `docker-compose stop`).
+2. Replace `Data/app.db` (local) or `./data/app.db` (Docker host) with a copy of the `pre-rollover-*.db` file from the backups folder.
+3. If needed, restore `CompetitionYear` in `Data/appsettings.json` / `./data/appsettings.json` (or Chapter Settings after restart).
+4. Start the application.
