 Do not run this check until AR51 confirms the functional test and creates a separate trusted approval record explicitly covering `api.zeroerr-agent.com`, the AM516 use case, and API-key use.
 
+## API Network Route
+
+The controlled query script defaults to `ZEROERR_AGENT_PROXY_MODE=direct` for
+`https://api.zeroerr-agent.com`. It uses a request-local opener with an empty
+proxy map, so this API does not inherit macOS or environment proxy settings.
+Feishu, Codex and other applications retain their existing network settings.
+The bridge launches the script for each query, so script updates take effect on
+the next query without restarting the bridge or clearing continuation context.
+
+On 2026-10-16, the proxy log for the 08:51 failed query showed a default-proxy
+connection timeout to this API. AR51-approved comparison queries with the fixed
+sample both succeeded later: system proxy 20.04 seconds, direct 4.79 seconds.
+These are individual observations, not an availability or latency guarantee.
+
+If another approved runtime requires a company proxy, configure
+`ZEROERR_AGENT_PROXY_MODE=system` in that runtime's environment (or the bridge's
+local `.env`, followed by a bridge restart). This selects the configured proxy
+route explicitly. It does not authorize a new destination. Invalid modes and
+direct requests outside the approved HTTPS hostname stop before the request.
+There is no automatic proxy fallback or extra API retry, and TLS certificate
+verification remains enabled.
+
 ## Normal TLS Trust Configuration
 
 The controlled query script injects `truststore` before making the request. Normal queries therefore keep TLS certificate verification enabled while using the macOS system trust store, including an AR51-approved company proxy root certificate installed and trusted in the system keychain.
