Relative TypeScript imports use .js extensions for Atomic's compiled package.
Atomic patches OAuth discovery to refresh changed authorization-server metadata.
OAuth client metadata documents and exact callback path checks are ported from
1499466d8581035a4dec6c869725b8712aea4bbe. Atomic does not use Pi's hosted client identity.
OAuth request cancellation and session close without a token refresh are ported from
f10993bc7f28145df1375f3ff39c7f5c4cfc05f0.
Upstream's license is reproduced below. The additional MCP TypeScript SDK
