Struct RiskOverlay 

pub struct RiskOverlay<'a> {
    pub engine: &'a EngineState,
    pub trigger: RiskOverlayTrigger,
    pub theme: Theme,
    pub now: DateTime<Utc>,
}

M2 §4 risk overlay. Surfaces the engine’s current Risk block alongside the operator-state snapshot’s vector components so a TILT + guardrail-proximity situation is unambiguous: the operator sees exactly how close to the hard alert they are, and why the classifier flagged the operator as TILT.

Design constraints (same spirit as StateOverlay):

• Context surface, not a gate — does not own a pending command, does not gate dispatch. Operator dismissal is any keypress; the auto-open hook will re-fire on the next tick if the guardrail signal is still live, subject to the 60 s cooldown.
• Descriptive, not judgmental. Numbers and distances only.
• L4 HardStop opens this overlay with a banner that says the engine is halted — the ceremony is context, not a bypass. Risk-reducing commands (/kill, /flatten, /cancel) still proceed through dispatch without the overlay blocking them (see two_am_scenarios.rs).

Trait Implementations

impl<'a> Debug for RiskOverlay<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Widget for RiskOverlay<'_>

fn render(self, area: Rect, buf: &mut Buffer)

Draws the current state of the widget in the given buffer. That is the only method required to implement a custom widget.
