Verified 2026-10-06 for comfy-dev: the gateway keeps no request or response
content. A canary sent through 'gen' appears in none of SpendLogs' text columns,
LiteLLM's container log, any ana-docker container log, or flash-next's log
(positive controls hit on the same stores). In 24h, 0 of 281,432 spend rows
carried messages, response or proxy_server_request. Langfuse is retired, there
are no DB-stored callbacks, and LiteLLM_ErrorLogs is empty. The per-request
no-log flag skips third-party callbacks but not the proxy's own spend-log
callback (v1.97 source), so the guarantee is this setting. Comment-only change;
the live file was updated in place with no restart.
