Upstream fix released: upgrade

cardano-api 11.0 → 11.11.0.0 crosses a breaking release

Own era handling: own-work. The CLI offers only the Conway era and maps Plutus script versions per era up to PlutusV3 in Conway; Dijkstra and PlutusV4 need new cases. A dependency solve (2026-10-22, scripts/readiness/bump-solve) resolves cardano-api 11.8.0.0 on GHC 9.6.7 only with four companion pins raised across majors: cardano-crypto-class to ^>=2.6, plutus-core and plutus-ledger-api to ^>=1.71, and validation to ^>=1.2; nothing was compiled.

Chain-facing capabilities

Findings describe behavior in a specific release and configuration. Suggestions need verification; historical findings do not establish behavior in the current source. None establishes hardfork compatibility.

No capability findings have been returned. Behavior remains unresolved; an empty list does not mean this tool has no chain-facing capabilities.
