Model-catalog shadow-compare fetch changes: network gating and caching

What

  • The background "shadow compare" fetch that checks the served/published model catalog now unconditionally allows network access for its own fetch path (a related sibling call still gates access based on whether Claude Code is running headless). The shadow-compare fetch only runs at all if an internal mode check doesn't disable it (covering environment overrides, bare mode, non-first-party or non-claude.ai auth, missing organization, or policy).
  • The shadow-compare check now first looks at a local cache entry and checks whether it is stale before deciding whether to make a network fetch, then writes the fresh (or errored) result back to the cache.
  • If the fetch does not finish within a fixed time budget, it no longer blocks; instead it schedules a background check to finish later and logs a new model_catalog_late_fetch event.

Why These changes make the background catalog comparison less likely to block or make unnecessary repeated network requests, while keeping the feature itself gated off unless explicitly enabled.

What has happened since
Flag reading moved The flag server now returns {"mode":"off"} for tengu_delegated_quail, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
