Walkthrough

The initial OIDC login and session reauthorization URLs now request offline access without adding prompt=consent.

Changes

OIDC authorization flow

Layer / File(s)	Summary
Offline access parameter src/handlers/http/oidc.rs	Both authorization URL paths append access_type=offline and no longer include prompt=consent.

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

Merge Risk: 🟡 Moderate · up to 6632e

The OIDC change removes the consent prompt from one flow but leaves it enabled for stale-session reauthorization, so users may still be forced through consent and the intended login behavior remains incomplete. This bounded correctness issue should be fixed or explicitly accepted before merge.

Poem

A rabbit hops through login’s gate,
Offline access joins the state.
No consent prompt adorns the way,
The OIDC flow is clear today.
“Hop-hop!” says Bun, “all set!”
