On the actual native buddy serve app using released Stacks 0.75.299 and STX 0.2.687, the marketing capability link navigated and updated its title, but clicking Sign in from the capability page and Create an account from /login left the URL and page unchanged. No browser errors/warnings appeared. Direct GET/navigation to /login and /register rendered the authored auth pages correctly, including at 320 px without document overflow. No credentials or provider flows were submitted.
Investigate the owning source before choosing a fix. Do not patch node_modules or emitted runtime files. If the cause belongs to STX or Stacks, add a real failing regression there, fix the source and run its native bun run release:patch, then consume and qualify that release in Farming.
Acceptance:
- Reproduce the stalled link activation on a minimal maintained source case and compare the previous published app baseline to distinguish existing behavior from migration regressions.
- Check pointer and keyboard activation, source click interception, route policy, returned response and focus handling for both auth paths.
- Fix the owning source, release it if it is a shared dependency, and consume the frozen published graph without patches.
- Verify capability-to-login and login-to-register navigation on desktop and 320 px, including title, URL, form rendering and browser errors. Do not create accounts or send messages during the check.
This observation is separate from issue #37's cold function-barrel failure. It does not claim a root cause or qualified authentication/provider delivery.
