fix(models): guard provider policy model shape

CHANGELOG.md

@@ -71,6 +71,7 @@ Docs: https://docs.openclaw.ai
 - CLI/image describe: pass `--prompt` and `--timeout-ms` through `infer image describe` and `describe-many`, so custom vision instructions and slow local model budgets reach media-understanding providers such as Ollama, OpenAI, Google, and OpenRouter. Refs #63700. Thanks @cedricjanssens.
 - Model selection: include the rejected provider/model ref and allowlist recovery hint when a stored session override is cleared, so local model selections such as Gemma GGUF variants do not fall back to the default with a generic message. Refs #71069. Thanks @CyberRaccoonTeam.
 - Local model prompt caching: keep stable Project Context above volatile channel/session prompt guidance and stop embedding current channel names in the message tool description, so Ollama, MLX, llama.cpp, and other prefix-cache backends avoid avoidable full prompt reprocessing across channel turns. Fixes #40256; supersedes #40296. Thanks @rhclaw and @sriram369.
+- Gateway/OpenAI-compatible API: guard provider policy lookup against runtime providers with non-array `models` values, so `/v1/chat/completions` no longer fails with `provider?.models?.some is not a function`. Fixes #66744; carries forward #66761. Thanks @MightyMoud, @MukundaKatta.
 - WhatsApp/Web: pass explicit Baileys socket timings into every WhatsApp Web socket and expose `web.whatsapp.*` keepalive, connect, and query timeout settings so unstable networks can avoid repeated 408 disconnect and opening-handshake timeout loops. Fixes #56365. (#73580) Thanks @velvet-shark.
 - Channels/Telegram: persist native command metadata on target sessions so topic, helper, and ACP-bound slash commands keep their session metadata attached to the routed conversation. (#57548) Thanks @GaosCode.
 - Channels/native commands: keep validated native slash command replies visible in group chats while preserving explicit owner allowlists for command authorization. (#73672) Thanks @obviyus.
