The KTD-8 startup adoption sweep mapped needs-replan to resume-graph, clearing
it on every engine restart. But needs-replan is not un-migrated legacy: post-U3
it is written live by the graph's plan-replan seam and is the exact status
triage's todo-rediscovery keys on to re-admit a planned todo task. Clearing it
stranded replan-loop tasks in todo forever (FN-8498 sat "ready" for 80 minutes
after a restart). Map it to preserve — the status is self-resuming as-is.
