Highest reader model verified across runtimes sharing the workflow resource. The deploy gate compares this reviewed numeric literal with the submitted definitions; do not import either exported reader constant, because a dependency upgrade must not change it automatically.
OptionalresourceResource-alias bindings for this deploy (alias name → physical resource).
A deploy-time abstraction ONLY: every @<alias>: reference in a
definition is expanded to its bound physical resource before the
deployed definition is fingerprinted and stored, and deploy fails closed
on an unbound alias. Aliases never exist past deploy — no stored
document carries one, the runtime never sees the map, and an
alias-shaped ref reaching a runtime boundary is rejected as malformed.
Omit for single-resource workflows (definitions referencing no aliases).
Authored definitions (the default — full compile-time checking) or loosely-typed fetched definition documents — the boundary parse normalizes either (WorkflowDefinitionInput).
