Add permission-revocation handling for live and offline sessions (#39)
Revoking write access must terminate live sessions and let a user with
pending offline edits export them rather than lose them silently.

Backend (generic, reused by M5 grants #53):
- packages/shared: POND_ACCESS_CHANGED_CHANNEL, the LISTEN/NOTIFY channel
  shared by api and collab.
- api: PondAccessNotifier emits pg_notify(pond_access_changed, pondId) on
  a permission-relevant change; the single generic seam for revocation.
  Wired into pond soft-delete as the interim trigger (see==modify until
  #53).
- collab: a dedicated-connection LISTEN listener (LISTEN is connection-
  bound, not pooled) that, on a notification, closes every open connection
  to the pond's open pages. Clients then reconnect and the api re-issues a
  token reflecting current access (downgrade to ro, or 403/404). Reconnects
  and re-LISTENs if its connection drops.

Frontend:
- use-collab-provider: a refused token (403/404) on (re)connect sets
  accessRevoked and stops the reconnect loop; exposes discardLocal.
- AccessRevokedDialog: keeps local content visible and offers Markdown
  copy/download (derived from the live editor doc, so offline edits are
  included) and an explicit discard that clears IndexedDB. de+en strings.

Tests: collab DB-backed integration test proves a direct NOTIFY closes a
live session within seconds (AC1) and leaves unrelated ponds untouched;
listener unit tests; api test asserts soft-delete fires the notifier;
web test for the export Markdown derivation.

Dorfteich

Dorfteich is an open-source wiki system built around ponds (German: Teiche) — self-contained wiki spaces that people and teams organize freely with hierarchical labels, directories, and Obsidian-style page relations. Pages are edited in a collaborative WYSIWYG editor with live cursors and offline support.

Key features

  • Real-time collaboration — multiple people edit the same page simultaneously; everyone sees the other participants' cursors and input live. Offline edits merge conflict-free on reconnect (CRDT-based).
  • Ponds — isolated wiki spaces with their own members, permissions, fonts, and page organization. Every registered person gets a personal pond.
  • Flexible organization — hierarchical labels, free page ordering, [[wikilinks]] with backlinks. A classic page tree is possible but never enforced.
  • Fine-grained permissions — roles (Site Admin, Pond Admin, Editor, Reader, Public) can be granted per pond, per label, or per page; the most specific setting wins.
  • Import & export — Markdown as the primary exchange format, plus best-effort structural import from Word/OpenOffice and export to Word/OpenOffice/PDF.
  • Plugins — sandboxed extensions (custom blocks, styles, page tools) installable at runtime without redeploying the instance.
  • Self-hosting first — a single docker compose up plus a guided first-run setup wizard yields a working instance.

Repository layout

Path Contents
docs/architecture/ Architecture documentation: ADRs, data model, permission model, collaboration and plugin concepts, deployment and operations
apps/ Application packages (web frontend, API server, collaboration server) — created as implementation proceeds
packages/ Shared packages (types, permission logic, plugin SDK)
deploy/ Docker Compose stacks and deployment tooling

Development

Requirements: Node.js ≥ 22 and pnpm (npm install -g pnpm).

pnpm install        # install all workspace dependencies
pnpm lint           # ESLint + Prettier check across the repo
pnpm typecheck      # TypeScript --noEmit in every package
pnpm test           # Vitest in every package
pnpm build          # build every package (dependency order)

The workspace packages live under apps/ (web, api, collab) and packages/ (shared). Shared logic goes into packages/shared and is imported as @dorfteich/shared — never copy code between apps.

Status

The project is in the architecture and backlog phase. Implementation stories are tracked as issues in this repository. Start reading at docs/architecture/README.md.
