+## Follow-ups without reopening
+
+Treat Ears `follow_up.review_needed` as activity evidence, not a judgment that
+reopening is required. Inspect new source comments and nested replies in context:
+classify acknowledgement, actionable request, or uncertainty, explain why, and
+recommend a response, reopening the same thread, a linked new task, or a
+clarifying question. A later maintainer message clears the observed waiting
+signal but is not proof the request was implemented. A fresh external comment
+restores it. Unknown coverage cannot establish that nothing is owed.
+
+Contributors may lack permission to reopen. A comment is sufficient to request
+attention; never make reopening a prerequisite or instruct a contributor to
+reopen as the only path. Direct triage reads `viewerCanReopen` for the acting
+account when possible; this says nothing about the contributor's permission.
+If false or unknown, refer reopening to a maintainer with permission. Do not
+conflate reopening, unlocking, and clearing an accepted answer. Each outward
+reply or state change still needs explicit authorization. The conductor's
+bounded direct comment read leaves response state unknown on settled threads
+when it cannot establish full post-settlement coverage; the Ears scan provides
+the paginated evidence. Fetch full relevant comments before making a judgment.
