 - Ollama: normalize provider-prefixed tool-call names at the native stream boundary so Kimi/Ollama calls such as `functions.exec` dispatch as `exec` instead of missing configured tools. Fixes #74487. Thanks @afurm and @carreipeia.
 - Security/audit: resolve configured model aliases before model-tier and small-parameter checks, so alias-based GPT-5/Codex configs no longer report false weak-model warnings. Fixes #74455. Thanks @blaspat.
 - CLI/agent: isolate Gateway-timeout embedded fallback runs under explicit `gateway-fallback-*` sessions so accepted Gateway runs cannot race transcript locks or replace the routed conversation session. Fixes #62981. Thanks @HemantSudarshan.
+- CLI/QR/device-pair: reject malformed public setup URLs before issuing mobile pairing bootstrap tokens, while keeping valid bare host:port setup URLs supported. Thanks @Lucenx9.
 - Models/UI: hide unauthenticated providers from the default Web chat, `/models`, and model setup pickers while keeping explicit full-catalog browse paths through `view: "all"`, `/models <provider> all`, and `models list --all`. Fixes #74423. Thanks @guarismo and @SymbolStar.
 - Slack/prompts: rely on Slack `interactiveReplies` guidance instead of generic `inlineButtons` config hints so enabled Slack button directives are not contradicted. Fixes #46647. Thanks @jeremykoerber.
 - Slack/reactions: treat duplicate `already_reacted` responses as idempotent success so repeated agent reaction adds no longer surface as tool failures. Fixes #69005. Thanks @shipitsteven and @martingarramon.
