   Its seven-service VM manager-start acceptance passed. It predates the rental
   and Fleet changes and is not an optimized release artifact.

+- VM update/rollback acceptance is still open. Properly awaited missing-plan
+  refusal passed; temporary tracing was removed. Reviewed-plan execution reached
+  Prepared/Editing/Restoring, but stopped before target startup because nginx -T
+  inherited the manager's read-only mount context. Proven helper fix b03d3c89
+  invokes that fixed inspection through a root system service;25 focused Python
+  tests pass. Candidate-helper standalone drain/backup qualification is underway
+  against the synthetic held operation before another embedded-hash backend build.
+  No controller hash bypass; original recovery images/journals/holds retained.
+  Earlier lock refusals were periodic reconciliation contention, not a proven
+  persistent source defect. Do not claim full rollback/update acceptance yet.
