 - Agents: revert accidental per-model thinkingDefault override merge. (#19195) Thanks @sebslight.
 - Sessions: revert accidental session transcript permission hardening from PR #18288. (#19224) Thanks @sebslight.
+- macOS/Update: correct the Sparkle appcast version for 2026.2.15 so updates are offered again. (#18201)
+- Gateway/Auth: clear stale device-auth tokens after device token mismatch errors so re-paired clients can re-auth. (#18201)
 - Voice call/Gateway: prevent overlapping closed-loop turn races with per-call turn locking, route transcript dedupe via source-aware fingerprints with strict cache eviction bounds, and harden `voicecall latency` stats for large logs without spread-operator stack overflow. (#19140) Thanks @mbelinky.
 - iOS/Onboarding: stop auth Step 3 retry-loop churn by pausing reconnect attempts on unauthorized/missing-token gateway errors and keeping auth/pairing issue state sticky during manual retry. (#19153) Thanks @mbelinky.
 - Fix types in all tests. Typecheck the whole repository.
