Live collaboration with Yjs over ActionCable

All editors now work on a server document at the same time instead of
taking turns behind an edit lock.

- The document's content is a sequence of Yjs updates (document_updates);
  DocumentChannel stores and relays them immediately, checks access on
  subscribe and again whenever links or memberships change.
- app/frontend/collab/: the store stays position-based; a binding maps it
  to a Yjs form with stable row/column ids, so a row inserted by one
  person doesn't misplace what another is typing. Remote changes are
  applied only after pending local ones went into Yjs.
- Per-person undo (Y.UndoManager), presence via awareness: the others'
  selections as coloured boxes with names, avatars in the toolbar.
- Existing JSON documents convert on first open, deterministically, so
  two people opening one at once end up with the same Yjs state.
- Editors compact the stored updates after 200 and keep a JSON snapshot
  current for export and duplicating. Edit lock and polling are gone.

# Live collaboration on one document (Yjs). Every edit is a Yjs update: the
# server stores it and passes it on to everyone connected; it never needs
# to understand what's inside. Binary data travels Base64-encoded.

# From the browser (perform):
# update { data } an edit (editors only)
# awareness { data } cursor/selection/name, not stored
# compact { state, ids, snapshot } replace the listed updates by one
# state; snapshot = JSON of the document
# snapshot { content } JSON of the document, for export etc.
#
# To the browser:
# init { role, title, updates: [{ id, data }], content? }
# content (JSON) only while no update exists yet: the browser
# then builds the Yjs form and sends it as the first update
# update { id, data, from } from = the sending subscription
# awareness { data, from }
# compacted { removed: [ids], id }
# meta { title }
# role { role } access changed

* - `Binding.sync(state)` DocumentState → Yjs, as the *smallest* set of
* changes (a cell, a property), so that edits by
* different people merge instead of overwriting
*
* Layout (root = ydoc.getMap('numolus')):
*
* locale, csvDelimiter plain values
* sheetOrder: Y.Array<id> sheets: Y.Map<id, Y.Map>
* sheet: name, locale, background, ... plain values (zoom stays local)
* objectOrder: Y.Array<id> objects: Y.Map<id, Y.Map>
* object: kind, name, x, y, ... plain values
* table additionally:
* rowOrder / colOrder: Y.Array<rowId | colId>
* cells: Y.Map<"colId|rowId", raw input>
* formats: Y.Map<"colId|rowId", CellFormat>
* colWidths: Y.Map<colId, px> rowHeights: Y.Map<rowId, px>
* fnOrder/fns, nameOrder/names, macroOrder/macros id-keyed lists
*
* Rows and columns have stable ids: the store addresses cells by position
* ("col,row"), Yjs by id. Inserting a row inserts one id into `rowOrder` --
* no cell moves -- so someone typing into row 7 while someone else inserts
* a row above still lands in the row they meant. The store reports such
* inserts/deletes explicitly (`Binding.structure`), because a diff of
* positional cells can't tell "row inserted" from "every cell below changed".

## Umsetzungsstand (Branch `with-server`, 2026-09-29)
Umgesetzt sind Phasen 1–3 in angepasster Form; Live-Sync (Phase 4) fehlt noch.
Umgesetzt sind Phasen 1–4 in angepasster Form, einschließlich Live-Bearbeitung mit Yjs.
| Thema | Umsetzung | Abweichung vom Konzept |
| --- | --- | --- |
| Anonym | Dokumente bleiben lokal in IndexedDB (`/?doc=<id>`) | kein Gast-Konto auf dem Server |
| Konto | Magic Link + 6-stelliger Code, Konto entsteht bei der ersten Anmeldung | – |
| Übernahme | nach der ersten Anmeldung Rückfrage, welche lokalen Dokumente hochgeladen werden; hochgeladene werden lokal entfernt | statt automatischer Übernahme |
| Server-Dokumente | JSON-Inhalt mit Versionsnummer, `/d/<id>`; mit Konto werden neue Dokumente auf dem Server angelegt | Inhalt noch nicht als Yjs-Stand |
| Gleichzeitiges Bearbeiten | Sperre pro Browser-Tab (90 s ohne Heartbeat), andere sehen „Nur Lesen“ und folgen per Abfrage alle 10 s | Übergang bis Phase 4 |
| Server-Dokumente | Inhalt = Yjs-Updates (`document_updates`), `documents.content` als JSON-Snapshot (Export, Duplizieren, erste Umwandlung); `/d/<id>` | – |
| Gleichzeitiges Bearbeiten | live über ActionCable (`DocumentChannel`), ~150 ms; feste Zeilen-/Spalten-IDs; Undo pro Person (`Y.UndoManager`); Auswahl der anderen als farbiger Rahmen | Store bleibt positionsbasiert, eine Binding-Schicht übersetzt (`app/frontend/collab/`) |
| Erste Umwandlung | JSON → Yjs deterministisch im Browser (feste Client-ID, IDs `r0…`/`c0…`), gleichzeitige Umwandlungen verschmelzen | statt serverseitig |
| Zusammenfassen | ab 200 Updates schickt ein Editor den Gesamtstand, der Server ersetzt die gelisteten Updates | clientseitig, kein `y-rb` nötig |
| Teilen per Link | ohne Konto nutzbar; Token im Browser gespeichert (localStorage), nach Anmeldung dem Konto zugeordnet | Link-Token im Klartext gespeichert, damit der Besitzer den Link erneut kopieren kann |
| Einladungen | Mail mit Link (7 Tage gültig), meldet gleichzeitig an | – |
| Sessions | signierte Session-ID im Cookie (Rails-8-Standard) | statt Token-Digest |
