Struct Limits 

pub struct Limits {
    pub max_steps: u64,
    pub max_recursion_depth: u32,
    pub max_output_bytes: usize,
    pub max_output_lines: usize,
    pub timeout: Duration,
    pub max_capability_calls: u32,
    pub max_value_bytes: u64,
    pub allow_clock: bool,
}

Configurable execution bounds.

Fields

max_steps: u64

Statements, loop iterations, and function calls one script may execute.

max_recursion_depth: u32

Maximum nested shell-function calls.

max_output_bytes: usize

Maximum accumulated output bytes.

max_output_lines: usize

Maximum accumulated output lines.

timeout: Duration

Wall-clock deadline for the whole script.

max_capability_calls: u32

Maximum capability invocations one script may drive.

max_value_bytes: u64

Maximum value bytes one script may materialize; see Budget::charge_value_bytes.

allow_clock: bool

Whether the date builtin may read the host wall clock.

This is the odd one out in this struct: it is a permission rather than a ceiling. It lives here anyway because it travels the same path every other bound does, from one CLI flag through one construction site, and a second parallel channel for a single boolean would be one more place for the two to disagree. Off by default: reading the clock is ambient authority, and with it off date is simply not a command this session has.
