What
Rather than guessing, auto-reply now defers when it cannot read who wrote a comment or whether it was sent to Claude.
Details
new defer notices: activation_read_absent (thread no longer shows as activated), newest_lane_unknown (newest comment's author lane unreadable, or an unknown-lane comment follows a sent-to-Claude human comment), and fresh_trigger_degraded
each reported once per thread through the existing artifact_comments_autoreact telemetry
Evidence
artifact_comments_autoreact
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
