Overview

Evaluation scope for an action’s ‘condition:` proc.

Exposes the contextual record as both ‘object` and `record`, and delegates everything else to the request’s **view context** — the object render components forward their helpers to — so a condition can use current_user, params, request, allowed_to?, resource_record!, etc. directly, exactly like the ‘condition:` procs on inputs/displays/columns.

Delegating to the view context (not a render component) matters: the component exposes params/request only as PRIVATE methods, which a delegator can’t forward; the view context exposes them publicly.

‘record`/`object` is the row/shown record for record and collection-record actions, and nil for resource/bulk actions (no single record in scope) — so guard with `object&.…` in conditions shared across action kinds.
