The platform no longer references Octokit.

This removes the transitional parts that kept Octokit.dll in the image for one cycle after the GitHub REST client was ported to a plain HttpClient:

• the <PackageReference Include="Octokit" /> in MeshWeaver.GitSync;
• the Octokit PackageVersion;
• the internal overload OctokitGitHubRepoClient.IsMissingOrEmptyRepo(Octokit.ApiException).

Both removal conditions from Doc/Architecture/GitHubSync hold:

1. MeshWeaver.Plugins#4206 merged at 2026-10-25 14:35Z. On Plugins main, every Octokit hit is a comment or core's OctokitGitHubRepoClient class name, which stays.
2. Instances run the Observability builds published after it.
   • On the control instance, the only package-update holds for Observability were on pearl (1.8.95 held below 1.8.104) and build (1.8.99 held below 1.8.100).
   • Both were resolved when those instances rolled past the floor (Hosting/Triage/package-update-held/pearl-observability and .../build-observability).
   • An image without Octokit reaches an instance only through a platform roll, and that same roll lifts any floor hold.

Satellites. I searched every .cs, .csproj, .props and .json file in shallow clones of the default branches of Education, Reinsurance, SocialMedia, Manufacturing, Crm, FundReporting, Memex and MeshWeaver.Deploy. The only hit is Memex's own PackageVersion Include="Octokit", which nothing there references.

Verified locally, Release with -warnaserror:

• MeshWeaver.GitSync, MeshWeaver.PluginCatalog, MeshWeaver.ComboAssembler, MeshWeaver.ComboVerifier and MeshWeaver.Hosting.Test build with 0 warnings and 0 errors.
• GitHubRestTransportTest: 53 of 53 pass.

Doc. GitHubSync: "Removing the transitional Octokit reference" is now "The transitional Octokit reference, removed", with the evidence above.

Pairs-with: Systemorph/MeshWeaver.Plugins#4206 — merged; it ported Plugins off the Octokit types and off the removed internal overload.

Satellite-pins: Octokit — searched every satellite's default branch as above. No versionless consumer: Plugins references no Octokit package, and Memex pins its own unused version.

🔵 Needs a closer look

Safe removal of the runtime DLL depends on deployed Observability bundles adopting the replacement, which remains independently unverified.
