Add version snapshots: automatic, named, thinning (#41)
Version history is a core kickoff decision (ADR 0013). Snapshots are full,
self-contained encoded Yjs states, so restore never depends on the update
log and compaction (#40) cannot lose history.

(The page_versions / page_pending_contributors tables and base schema
landed a commit early, bundled into 3583a04; this commit completes #41.)

- schema: page_versions gains created_by (editor of manual/pre-restore
  versions; null for automatic snapshots). shared: PageVersionView,
  CreateVersionInput, PageVersionTrigger.
- collab: PostgresVersionStore tracks contributors per open doc (onChange),
  flushes them to the shared page_pending_contributors accumulator on store,
  creates an automatic snapshot on last-participant disconnect (only if
  something changed — no duplicate on a quick reconnect) and every 30
  active-editing minutes. Contributors and snapshot are consumed atomically.
- api: POST /pages/:id/versions creates a named version (write permission,
  label + creator, snapshot reconstructed from persisted state, consumes the
  same contributor accumulator). Daily version-thinning scheduler job keeps
  all versions for 90 days, then the newest auto snapshot per day; manual and
  pre-restore versions are never thinned. pre_restore trigger reserved for #42.

Tests: collab (one auto version on session end with the full two-author
contributor set, none when unchanged, no duplicate on reconnect, interval
snapshot); api (named version stores label+creator, contributor set consumed,
non-owner refused, thinning time-travel keeps newest-per-day beyond window).

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.
