Crate jar_kernel 

JAR v3 kernel.

Composes the foundational cap system (javm-cap), the pure execution engine (javm-exec), and the integration crate (javm) into the chain-side kernel: σ state, block apply, state-root, kernel-assisted Instance impls, host_open/host_save.

σ is a [javm_cap::CacheDirectory] plus the validator set; cap content (Images, Data, CNodes, Instances) lives in the cache and is content-addressed by [javm_cap::CapHash]. apply_event publishes the event payload as a DataCap, rebinds the chain root cnode’s slot[0] to it, and drives [javm::Vm::invoke_cached].

Modules

abi

Slot numbers the v3 chain ABI exposes to chain Instances at genesis. Sourced from [javm_cap::abi] so the transpiler can reference the same constants when building chain Images.

apply

Block apply driver.

error

Errors surfaced by the v3 jar-kernel.

genesis

Chain genesis: σ initialization + kernel-cap injection.

kernel

Top-level Kernel API.

kernel_assist

σ-aware [javm::KernelAssist] implementation.

state

σ — the v3 chain state.
