Summary

• Narrow the absolute never-reread rule to discourage redundant unchanged re-read loops
• Explicitly permit unread pages, changed content, targeted uncertainty resolution, and compaction-lost evidence recovery
• Require necessary rereads to state a reason with bounded scope

Verification

• bun run check passes including the full guarded suite
• Guidance tests fail without the new wording and pass with it
• Live-model improvement measurement remains pending on the collaboration eval lane
