Walkthrough

UserRegisterWithCodeHandler.get now returns the OAuth provider’s lockUsername setting. The registration form makes the username readonly for locked providers and moves autofocus to the password field. UserRegisterWithCodeHandler.post uses the token’s top-level username value for locked providers.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🟡 Moderate · up to 5a023

The registration flow can indicate that sign-up is available while rejecting the submission because the required OAuth provider is unavailable, leading to a confusing failed registration. This bounded correctness issue should be fixed or explicitly accepted before merging.

Reject invalid locked-provider usernames before creating the registration token.

OAuthUserResponse.uname is optional, and the handler stores '' when no candidate is available. A locked provider can also return a candidate that fails Types.Username; Line 325 then rejects registration. Validate the selected username before storing the token.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not report a missing provider as unlocked.

If this.tdoc.identity.provider is absent from this.ctx.oauth.providers, this code returns lockUsername: false, while UserRegisterWithCodeHandler.post rejects the same token at Line 323. The response then advertises an editable username state for a registration that cannot succeed. Fail in get as post does, or return an explicit unavailable state instead of false.
