Struct SessionBudgetPolicy 

pub struct SessionBudgetPolicy {
    pub default_cap: Option<u64>,
    pub overrides: BTreeMap<String, Option<u64>>,
}

Per-session budget caps for the apply-path gate (#292 slices 2 and 3). The default_cap field applies to every session not listed in overrides. Within the overrides map, a value of Some(n) sets that session’s cap to n, and an explicit null means the session is unbounded — the escape hatch for ops outside the budget envelope, e.g. one-shot human interventions.

Absence of session_budgets keeps current (#292 slice 1) behavior: spending is recorded but never refused.

Fields

default_cap: Option<u64>

overrides: BTreeMap<String, Option<u64>>

Per-session overrides. Outer Option: presence in the map. Inner Option: Some(n) is a cap of n; None is the explicit “unbounded for this session.”

Implementations

impl SessionBudgetPolicy

pub fn is_empty(&self) -> bool

pub fn cap_for(&self, session_id: &str) -> Option<u64>

Resolve the cap for a given session. The lookup is:

1. If overrides has the session_id, use that entry’s value (which itself may be None meaning unbounded).
2. Otherwise fall back to default_cap.
3. Return None for “no cap; don’t enforce.”
