Per-iteration scope source materialised by `expandInstanceNodes` inside every forEach iteration. Replaces the F351 reserved-token substitution mechanism (`$match`, `$index`) with a port-driven model — template-body nodes wire from this node's outputs the same way they wire from any other producer. Authors do NOT write this node by hand; the loader emits one per iteration with constant per-iteration values.

Outputs

selector | string | Per-iteration matched-element CSS selector. Empty when the parent instance has no `forEach`. |
index | float | 0-based iteration index. |
count | float | Total iteration count for this forEach. |
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
| - | - | - | No configurable parameters. |
Use cases
- Inside a forEach template, wire `selector` into a writer's selector input port (replaces `"selector": "$match"`).
- Inside a forEach template, wire `index` into an indexed-aware consumer (e.g. `sectionAlphaGate.myIdx`) (replaces `"myIdx": "$index"`).
- For embedded selector composition (`"$match .child"`), wire `selector` into a `selectorJoin.prefix` and set `suffix: " .child"`.
- Custom overridables surface as additional output ports on the scope, carrying the per-iteration resolved value with the same name as the overridable.
