OidcBrowser opens the page of an attempt the server began (OidcStart), waits until the browser comes back by an OidcReturn (the app's scheme, a verified https address, or the loopback) and returns the provider's code (OidcCode), its refusal (OidcDenied), or nothing when the person closed the browser. It checks the returned state against the attempt's, as the server never compares it; a wrong state, neither one code nor one refusal, no browser or a failed way back are OidcCallbackExceptions. halkyon_app's LoopbackWebAuth moves in with its tests, relicensed from AGPL v3 to BSD-3-Clause by its author, the developer; GitHub's sign-in keeps using it from there until it ends. The package is BSD-3-Clause, publish_to: none, as the module (ADR 0023, D2, D3). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Signed-off-by: Tizian 「ティツィアーン」 <raisondetredev@pm.me>
