Let users remove a synced book from the dashboard

[itsthisjustin]

The Synced books page could only ever show books. Once something synced — a book you no longer have, a test file, a duplicate hash — there was no way to get it off the dashboard or out of kosync.

What's new

Each book on /progress gets a Remove button, behind a confirm that spells out exactly what's deleted.

It calls a new DELETE /api/v1/progress/{document}, which clears every row that book owns for that user:

• kosync progress for all devices, and progress_samples
• documents metadata
• bookmarks and clippings
• per-book stats (stats_device_book)
• connector_matches and any queued connector_queue events

Returns {document, deleted: true, rows}, or 404 {"code": 2003, "message": "Unknown document"} when the user has no data for that document.

Afterwards the device's own GET /syncs/progress/{document} goes back to returning {}, so a reader that still holds the file starts over rather than restoring the old position.

Notes on behavior

Bookmarks and clippings are hard-deleted, not tombstoned. With the book gone there's nothing left to delta-sync against. A device that still has the file simply re-uploads its state on the next sync — this is a server-side reset, not a device-side delete. The confirm dialog and docs/API.md both say so.

Removal is not permanent if the book is still on a device. Reading it again re-syncs it as a new book. That's stated in the confirm text so it isn't a surprise.

The table list lives in one place (src/models/document.ts), so it can't drift as tables get added.

Drive-by fix

deleteKosyncUserData in src/routes/account.ts never cleared progress_samples, orphaning those rows when a sync account or login was deleted. Since users.id is an INTEGER PRIMARY KEY, SQLite can reuse a deleted id — a new account could have inherited someone else's position samples. Added to the list.

Testing

• Full suite green: 263 tests, 8 new — cross-user isolation (same document hash, two users), 404 on an already-removed book, malformed document ids, and a per-table assertion that the removed book's rows are gone while a second book's survive.
• tsc --noEmit clean; the generated inline page script syntax-checked via node --check.
• End-to-end against a live server through the browser's cookie-auth path (which the header-auth tests don't cover): signup → link kosync account → device pushes progress → remove from dashboard → book gone from the list, {} from kosync, 404 on a second remove.

📝 Walkthrough

Walkthrough

The change adds per-user synced-book deletion across stored document data, exposes it through DELETE /api/v1/progress/{document}, documents and tests the endpoint, and adds a Remove action to the web progress page.

Changes

Synced book deletion

Layer / File(s)	Summary
Document cleanup primitives src/models/document.ts, src/routes/account.ts	The document model checks for stored document data and transactionally deletes matching rows across document-related tables. Permanent kosync user deletion also removes progress_samples rows.
Delete endpoint and validation src/routes/v1/progress.ts, docs/API.md, test/progress.test.ts	The API validates document identifiers, returns defined errors for invalid or unknown documents, deletes matching data, and reports the removed-row count. Tests cover cleanup, user and document isolation, repeated deletion, and malformed identifiers.
Web book removal UI src/routes/web.ts	The progress page renders Remove buttons, confirms deletion, calls the delete endpoint, displays non-success errors, and removes deleted books from the list.
