Enum Mode 

pub enum Mode {
    Normal,
    Sandbox,
}

Execution mode of a FlowLocal, baked in at construction/fork time and read by ContextView to decide how it routes every unit.

Mode is orthogonal to WorldPolicy/ResolvedPolicy: policy homes a unit (a global, a knot’s visit count, …) to World or Local; Mode decides, for this flow, whether that homing is honored at all.

Variants

Normal

Route every unit by policy, exactly as ContextView’s F2.2/F3.1 docs describe: World-scoped units go straight to World, Local-scoped units chain-read-through/write to FlowLocal. Every construction path before F3.2 produces Mode::Normal — this is what keeps the oracle corpus byte-identical.

Sandbox

Treat every unit as Local, regardless of policy: the shared World becomes a read-only base for this flow. Reads still chain-read-through to World’s current value on a total miss (so a sandboxed flow sees live world state), but writes always land in this flow’s own top-layer overrides — World (and any Normal ancestor) is never mutated. Combined with FlowLocal::fork’s frozen base, this is the side-effect-proof primitive watch/eval needs: run a flow against current state, observe its output, then discard it (drop) with the shared world untouched.
