Weapon & Prop

Make an object that is the same object in every shot.

Which objects need this

Object	Needs a sheet?	Why
Appears in two or more blocks	yes	recurrence is identity
Held in close-up	yes	it fills the frame; it must be real
Carries text, a number or a logo	yes, plus a text pass	text is where drift shows first
Is a story clue (the compass, the brooch)	yes	continuity-critical by definition
Marks an era (an old ball, a homemade trophy)	yes	props sell the period fastest
Set dressing (lamps, plants)	no — lives in the location plate	nobody tracks it
Crowd items in bulk	no — text only	no individual identity

Rule: if the next generation will show this object and a viewer would notice it changed, it gets a sheet.
