Architecture

Four layers. Each works on its own; none requires the others.

Layer What it is How you reach it Code Runs on your machine
Repertorium Legal knowledge infrastructure: a corpus of Polish and EU law with a citation graph and PL-EU links web console, remote MCP, REST hosted service; interface and response contract documented in the open as a local data pack, by agreement
PATRON Local-first legal workspace: case files, chat, tracked-changes drafting, audit trail Windows desktop app, 9 language editions AGPL-3.0 yes; the model is local or a cloud one you choose
Boutique Catalogue of MCP connectors and agent skills uvx / npx / npx skills add, catalog.json MIT / Apache-2.0 yes; connectors query public sources from your machine
MateMatic Architecture, reliability audit and deployment inside a firm contact governance documents are open -

PATRON reaches Polish and EU sources through its own bundled connectors today; wiring it to Repertorium is planned.

Corpus or live query

The two words mean different things here.

  • Corpus (Repertorium, and the offline connectors mcp-eu-compliance, mcp-fr-legal, pk-eli-mcp): a snapshot of the law with a known state date. Fast, joinable, citable - and as current as its last build.
  • Live query (most connectors): the request goes to the official source at the moment you ask. As current as the source itself - and only as available and as structured as that source is.

Look under the hood

Claims are cheap; these are the parts you can inspect.

  • Citation contract - MCS v0.1: the source_id / url / exact_quote / locator / confidence shape PATRON verifies citations against, with a conformance test a connector can run.
  • Response contract - Repertorium answers are ok, partial (with the shards that failed named) or search_unavailable. An empty list is never passed off as an honest zero. Details.
  • Audit trail - PATRON hash-chains every model interaction and exports a ZIP with its own verifier, and the documentation says what the trail does not prove (ADR-0142, audit trail).
  • Decisions - Architecture Decision Records and the AI Constitution a firm reads before deployment.
