Open Brain REST API source labeling: The /capture endpoint in open-brain-mcp/index.ts (line 267) hardcodes source: "chatgpt" for all POST requests. This means Gmail bridge captures also show as source "chatgpt" since the Apps Script POSTs to the same endpoint. No emails are actually being forwarded through ChatGPT. To distinguish Gmail vs ChatGPT captures in the future, the Apps Script could pass a source field in the POST body and the edge function could respect it instead of hardcoding. Low priority, cosmetic only.
