What

Comment threads are now classified per comment into human, agent and unknown lanes, and sending or re-sending a comment to Claude is itself a trigger for auto-reply rather than only a new comment being one.

Details
  • each comment carries a lane; a toClaudeAt timestamp marks it as sent to Claude
  • new trigger kind redesignated covers existing comments newly toggled to Claude, tracked through a per-thread sentToClaudeAt map
  • the composed prompt now explains the row heads [human], [assistant], [human, sent to you] and [unverified lane]
Evidence

A human sent an EXISTING comment in the thread to you on an artifact you published

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
