  Jam.gg's first-party developer libraries are published from the GitHub organization
  https://github.com/piepacker (org display name "Jam.gg" — the company shipped as Piepacker
  before the 2022 rebrand and never renamed the org). Registry metadata was read from
  Maven Central directly (repo1.maven.org maven-metadata.xml) because the solrsearch index
  returns 0 results for the io.github.piepacker group. Two of the three first-party libraries
  are distributed as source only (Unity assets / native plugin DLLs committed to the repo) and
  therefore have no registry metadata endpoint to query; their currency is recorded from the
  last push to the default branch. Nothing was found on npm, PyPI, NuGet, RubyGems, crates.io,
  Packagist or pkg.go.dev under any jam.gg / jamgg / piepacker name. An npm package named
  `jampad` exists (0.0.1-alpha.2, 2025-07-15) but declares no repository, description or author
  and CANNOT be attributed to Jam.gg, so it is deliberately excluded.

  note: >-
    All five platform artifacts carry the same release 0.1.0-alpha4 with lastUpdated
    20250331193441. Still pre-1.0 alpha; the only GitHub release/tag is 0.0.1-alpha1
    (2024-05-02), so the published alphas after that are untagged.

    "Software Development Kit for games on Jam.gg" — a P/Invoke C# binding over a native
    jam_sdk shared library. It exposes the session context the Jam.gg runtime injects into a
    hosted game process: set_env_path, get_cluster_name, get_connection_host, get_player_idx,
    get_session_id, get_user_session_id. This is an FFI surface, not an HTTP API — there is no
    REST/GraphQL contract to describe.
  note: >-
    Distributed as source + committed prebuilt binaries (jam_sdk.dll, jam_sdk.so); there is no
    package registry entry and no tags or releases, so version/published are null — checked,
    nothing to record. Last push to the default branch was 2022-12-13. The repository carries no
    LICENSE file. get_display_name is commented out in the binding with the note "no longer
    implemented serverside", an in-source decay marker.

  description: >-
    Unity JsLib plugin that bridges a WebGL game to the Jam.gg (Piepacker) browser host, exposing
    SessionID, UserSessionID, UserID, PlayerIdx, ClusterName, ConnectionHost and DisplayName as
    extern C# calls. The browser-side predecessor to JamSDK-Public.
  note: >-
    Source-only Unity plugin — no registry, no tags, no releases, so version/published are null.
    Last push to the default branch was 2022-05-13. Superseded in practice by JamSDK-Public.
