# bb-runtime — sans-IO engine for the bytesandbrains framework.
#
# Hosts Node + Engine + Framework + role-runtime traits + Contract
# trait family + the runtime-side syscall registration framework
# + snapshot/restore.
#
# Depends on: bb-ir (foundation). NOT bb-compiler — bb-runtime
# accepts the compiled `ModelProto` directly via `bb_runtime::install`
# and never re-runs the compiler.
