Milestones

High-level, not exhaustive

  1. Open source Kin (Apache-2.0)

    Shipped

    The semantic engine, graph format, retrieval internals, and CLI are open source on GitHub under Apache-2.0. Code is parsed into a semantic entity graph you can run, read, and audit locally.

  2. Bundled MCP server: semantic tools for AI agents

    Shipped

    The MCP server bundled in Kin exposes semantic tools including locate, context packs, trace, and review. Kin setup configures supported detected clients; kin setup status is the authority for what this machine actually has configured.

  3. Kin VFS: graph-backed projection on compatible hosts

    Shipped

    The released VFS projects graph-backed files through libc interposition on compatible glibc Linux and macOS hosts. Native Windows has no VFS; Alpine/musl and some Debian 12-class hosts may run the Kin core without projection; macOS injection is subject to SIP and hardened-executable limits.

  4. Reproducible proof package

    Shipped

    A pinned internal proof harness with a gate that only counts results carrying a real tool-call trace. Its one published result is retrieval determinism. On the frozen 26-task suite the run ties the baseline on file localization and matches it on cost. The claim and its caveats live on the proof page. The harness repository is private today, so public one-command replication is not yet available.

  5. KinLab for teams

    In early access

    KinLab adds shared repository graphs, advisory AI review, and early-access agent controls for teams. Access is available by request.

  6. Cross-repository relationships

    In progress

    We are extending Kin across repositories so teams can follow likely impact and supporting context throughout an organization.

This page stays milestone-level on purpose. For dates, downloads, and notes for each Kin version, see GitHub releases. For the retrieval claim and its caveats, see the proof page.
