Editing MCP/Guidelines (section)

== Architecture ==

The guidelines are loaded at server startup and cached for the lifetime of the MCP server process. Restarting the container is required after editing guideline files.

* '''Core text''' lives in <code>duralex-mcp/src/duralex/mcp/core.md</code> and is loaded by the MCP server directly (not by plugins).
* '''Jurisdiction texts''' are provided by each jurisdiction plugin via the <code>get_guidelines() -> str</code> protocol. Each plugin returns a single jurisdiction-scoped supplement.
* '''Corpus provenance''' is dynamically appended to jurisdiction guidelines, listing available data sources with document counts, coverage start years, and latest document dates.

Single-jurisdiction variants (e.g., <code>"fr"</code>, <code>"eu"</code>) are precomputed at registration time. Multi-jurisdiction variants (e.g., <code>"eu|fr"</code>) are built on demand by concatenating the relevant single-jurisdiction variants.

The <code>jurisdiction</code> parameter supports Overpass QL operators: <code>"fr"</code>, <code>"eu"</code>, <code>"eu|fr"</code> (combined), <code>"*"</code> (all jurisdictions), <code>"!=eu"</code> (exclusion). The <code>"!*"</code> operator is not allowed.
