Struct JavascriptExecutionLimits 

pub struct JavascriptExecutionLimits {
    pub v8_heap_limit_mb: Option<u32>,
    pub sync_rpc_wait_timeout_ms: Option<u64>,
    pub cpu_time_limit_ms: Option<u32>,
    pub wall_clock_limit_ms: Option<u32>,
    pub import_cache_materialize_timeout_ms: Option<u64>,

    pub bridge_call_timeout_ms: Option<u64>,
}

Per-execution JavaScript runtime limits, carried as typed fields on the execution request rather than AGENTOS_* env vars. The sidecar populates these from the per-VM VmLimits (which originate from CreateVmConfig on the BARE wire); None selects the engine default. See the env-vs-wire rule in crates/sidecar/CLAUDE.md.

Fields

v8_heap_limit_mb: Option<u32>

V8 heap cap in MB. None/Some(0) keeps the engine default heap.

sync_rpc_wait_timeout_ms: Option<u64>

Sync-RPC blocking-wait ceiling in ms. None keeps the engine default.

cpu_time_limit_ms: Option<u32>

Active JavaScript CPU-time budget in ms. None keeps the engine default; Some(0) disables the CPU watchdog.

wall_clock_limit_ms: Option<u32>

JavaScript wall-clock backstop in ms. None keeps the engine default; Some(0) disables the wall-clock watchdog.

import_cache_materialize_timeout_ms: Option<u64>

Timeout for materializing the per-VM Node import cache.

max_timers: Option<usize>

Maximum live JavaScript timers in this execution. None keeps the engine default. The sidecar supplies the VM-scoped configured value.

reactor_work_quantum: Option<usize>

Maximum readiness identities delivered in one V8 turn. Sidecar VM execution must supply limits.reactor.workQuantum here.

bridge_call_timeout_ms: Option<u64>

Per-call host bridge deadline. Sidecar VMs supply limits.reactor.operationDeadlineMs; zero is invalid.
