Could the ledger's signature methods be upgraded later?
Designed, not yet built
Short answer
No. The specification describes it, but the pilot does not include it. For reference, REQ-3013 (a high-priority requirement, the medium and large tiers) says signature algorithm identifiers must be carried in every ledger message to allow crypto agility including hybrid PQC. Check: a test message signed under a second suite validates.
This is designed, not built.
