Statement
Crypto agility and toolchain escrow reduce obsolescence risk in medical, energy, transport, and public systems.
Evidence dimensions
- Basis
- proposed
- Readiness
- major scale up
- Confidence
- supported
Assessment rationale
NIST guidance directly treats algorithm replacement, cryptographic inventories, key lifecycle, secure development, supply-chain visibility, and transition continuity as current risk-management needs. Preserving build tools, source, specifications, and recovery knowledge as an escrowed local capability is a systems inference rather than a directly demonstrated cross-sector program.

Assumptions and limits
The assessment applies to this bounded statement and the cited source scopes. A source can support one relationship without validating a generation ship, and an editorial grade does not substitute for independent review or representative demonstration.
What would change this conclusion?
Longitudinal evidence from medical, energy, transport, or public systems should compare migration time, outage, stranded assets, security regressions, and recovery with and without maintained inventories and locally recoverable toolchains. Evidence that escrow increases compromise or obsolescence risk more than it reduces transition risk would narrow the claim.
