Struct PythonExecutionLimits 

pub struct PythonExecutionLimits {
    pub output_buffer_max_bytes: Option<usize>,
    pub execution_timeout_ms: Option<u64>,
    pub max_old_space_mb: Option<usize>,
    pub vfs_rpc_timeout_ms: Option<u64>,
    pub reactor_work_quantum: Option<usize>,
    pub bridge_call_timeout_ms: Option<u64>,
    pub max_open_fds: Option<usize>,
}

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

Fields

output_buffer_max_bytes: Option<usize>

Captured-output buffer cap in bytes. None keeps the engine default.

execution_timeout_ms: Option<u64>

Execution wall-clock cap in ms. None keeps the engine default; Some(0) disables the timeout.

max_old_space_mb: Option<usize>

Pyodide V8 old-space cap in MB (0 keeps the V8 default). None keeps the engine default.

vfs_rpc_timeout_ms: Option<u64>

VFS sync-RPC wait ceiling in ms. None keeps the engine default.

reactor_work_quantum: Option<usize>

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

bridge_call_timeout_ms: Option<u64>

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

max_open_fds: Option<usize>

Maximum host-direct descriptors retained for managed Pyodide assets. None keeps the execution engine’s bounded fallback. The native sidecar always supplies the VM kernel’s configured descriptor limit.
