What causes the OpenClaw tag bug?

A greedy regex in the SSE pipeline strips tags that span chunk boundaries, eating adjacent content too.

How do I test for SSE streaming bugs?

Diff stream:true vs stream:false outputs char-by-char, especially payloads splitting across chunks.

Is OpenClaw safe for production AI agents?

Not yet — fix this first, then stress-test edges. Streaming's still rough.
