DeepInfra catalog (fetched with the launch env's key via os.getenv), Copilot
context limits (api_key ignored on hit), Nous reasoning caps + once-per-process
guards, the curated OpenRouter list, the model-catalog in-process copy (mtime
without path), banner skills, the guest-mint back-off flag and the active skin
were single slots read under per-profile overrides by the gateway and the TUI
gateway; the SWR refresh thread ran without the caller's ContextVars.
Under an override each lives per home key (hermes_cli/models_profile_cache.py
holds the shared slot helper so models.py does not grow), credentials are read
through the scope-aware dotenv reader and keyed by fingerprint, and background
refreshes run under copy_context(). Unscoped behaviour is byte-identical.
