- .sops.yaml: add hc_vault_transit_uri for transit/keys/sops-state - state-sync: try Vault Transit first, fall back to age key on disk - Re-encrypted all 101 state files with both Vault Transit + age - Normal workflow: vault login → decrypt via Transit (no key files) - Bootstrap/DR: age key at ~/.config/sops/age/keys.txt
