Cropped companion sheets visible behind foreground drawing are excluded. Partial timed visual review: undefined Partial timed visual review: Bounded hardware, profile and support note review; no building placement or accepted geometry. Partial timed visual review: Source-local depicted assembly or specification only. No installed quantities, accepted floor geometry or model placement inferred. Partial timed visual review: Depicted type/component, shop order or source-local assembly only. Components and grille order quantities do not create installed fixtures or establish electrical outlet-to-type assignments.
