# Changelog

> Notable changes to the Locus knowledge layer.

<Update label="v0.2" description="Surface narrowed to search, answer, and context">
  The API surface is trimmed down to the capabilities that carry the product.

  **Removed:**

  * `analyse` — the `POST /v1/analyse` endpoint and the `analyse` MCP tool are
    gone. Rule evaluation over health records is no longer part of the
    knowledge layer.
  * The experimental knowledge-graph context endpoint (`POST /v2/context`) and
    its playground route are withdrawn. The stable
    [`POST /v1/context`](/en/capabilities/context) is unaffected and remains
    the supported way to get a patient-aware answer.

  **Unchanged:** `search`, `answer`, and `context` keep their contracts on both
  REST and MCP. `atb` and `drug` stay on the roadmap.
</Update>

<Update label="v0.1" description="Initial knowledge layer">
  First release of the Locus knowledge layer — REST + MCP over the shared
  clinical knowledge base.

  **Capabilities (REST + MCP):**

  * `search` — structured, citable retrieval.
  * `answer` — grounded, cited answers.
  * `context` — answer accounting for a coarse patient profile, with conflicts.
  * `analyse` — apply a clinical rule to inline health records, with sourced
    recommendations.

  **Platform:**

  * Bearer `lsk_…` authentication against the shared key store.
  * MCP server over Streamable HTTP with curated tools and output schemas.
  * Auto-generated API reference with an interactive playground.

  **Roadmap:** `atb` (deterministic antibiotic decision) and `drug` (BDPM
  medication data) are designed, not yet available.
