}

Per-execution WebAssembly runtime limits, carried as typed fields rather than AGENTOS_WASM_* env vars. Populated by the sidecar from the per-VM kernel ResourceLimits (originating from CreateVmConfig on the BARE wire); None selects “unlimited / engine default”. See the env-vs-wire rule in crates/sidecar/CLAUDE.md.

Fields

max_fuel: Option<u64>

Fuel budget, enforced as a wall-clock timeout (ms) by the WASI runtime.

max_memory_bytes: Option<u64>

Linear-memory cap in bytes, validated against the module’s declared initial/maximum memory before execution.

max_stack_bytes: Option<u64>

Stack cap in bytes. Until the V8 runner exposes an enforceable per-module stack lever, any configured value fails closed rather than silently using V8’s unrelated default stack bound.

max_module_file_bytes: Option<u64>

Maximum executable image bytes accepted for initial and replacement modules. The trusted runner needs the typed value for fexecve preads.

max_spawn_file_actions: Option<u64>

Maximum number of file actions decoded for one posix_spawn call.

max_spawn_file_action_bytes: Option<u64>

Maximum serialized file-action bytes accepted for one posix_spawn call.

max_open_fds: Option<u64>

Maximum guest-visible open descriptors, including runner-owned sockets.

max_sockets: Option<u64>

Maximum runner-owned guest sockets.

max_blocking_read_ms: Option<u64>

Maximum time a blocking runner syscall may cooperatively wait.

prewarm_timeout_ms: Option<u64>

Best-effort warmup/compile-cache timeout in ms.

runner_heap_limit_mb: Option<u32>

V8 heap cap for the trusted JS runner isolate that hosts WASI/WASM.

runner_cpu_time_limit_ms: Option<u32>

Active-CPU cap for the trusted JS runner isolate that hosts WASI/WASM.

reactor_work_quantum: Option<usize>

VM readiness work bound forwarded unchanged to the WASI V8 runner.

bridge_call_timeout_ms: Option<u64>

Per-call host bridge deadline forwarded unchanged to the WASI V8 runner.
