Summary

• retain the exact lowid.buddy-callback slice contract and focused harness operating objective
• record the final bilateral artifact, immutable receipt, revisions, causal sequences, and complete green gates
• advance measured catalog coverage without starting another protocol slice on this branch
• require coordinated delivery and branch retirement before selecting the next incomplete catalog ID

Result

• catalog coverage is 27/100 IDs and 5/17 complete groups
• lowid-callbacks is complete at 4/4
• missing or unrecorded evidence remains evidence-incomplete, never parity or divergence
• ed2k-server remains untouched and upstream-clean
