Module vm 

M5: bytecode VM. Stack machine with effect dispatch through a host handler.

Structs

DenyAllEffects

A handler that fails any effect call. Useful as a default for pure-only runs.

NullTracer

No-op tracer for normal execution.

Enums

VmError

Constants

MAX_CALL_DEPTH

Maximum simultaneous call frames. Defends against unbounded recursion in agent-emitted code: a body that calls itself without a base case would otherwise blow the host’s native stack and crash the process. Real Lex code rarely exceeds ~30 frames; 1024 is generous headroom while still well under the OS stack limit at any per-frame size we use.

Traits

EffectHandler

Host-side effect dispatch. Implementors decide what kind/op mean and how arguments map to side effects.

Tracer

Trace receiver. Implementors record the call/effect tree and may substitute effect responses (for replay).
