For Remote Control sessions with CLAUDE_CODE_WEBSEARCH_USE_CCR_PROXY=1 set, web searches are now routed through the Anthropic API's session WebSearch proxy (/worker/web-search) instead of directly to the search provider. Error messages from the proxy are surfaced clearly with type-specific descriptions.
Evidence
New L8a() function — search for "ccr websearch-proxy transport error" and "/worker/web-search"
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
