• ✓The game is not the rubbing: every job has a right way, and it is right for a reason you can say out loud
• ✓Scales overlap tailwards so you scrape against them · feathers lean tailwards so you pull with them · shear in one long stroke because a second pass leaves fibres too short to spin · milk downwards or it goes back up inside — all four are true of the real job
• ✓The last stage teaches nothing new on purpose — a goat is milked exactly like a cow, and the game says so before you start rather than after
• ✓A method that only works on the animal you learned it on is a trick; one that moves to the next animal is knowledge — and naming that transfer out loud is what turns one into the other
• ✓The stroke is measured — direction and length — and sheep is the only stage where direction does not matter and length does, because that is exactly how shearing differs
• ✓A miss is answered with the reason again, never a cross; and after three the game offers to do the stroke once, slowly, the way a person standing beside them would
• ✓The verifier proved all 22 spots before any UI existed: a correct stroke passes, a short one does not, a backwards one does not — and it refuses the file outright if the goat ever stops using the cow's technique
• ✓All five animals are Kidsquare's own paintings, cut off their cream vocabulary cards and standing on the painted farmyard plate — not one new picture was needed
• ✓Play-tested at 390px through all five stages: backwards strokes refused on every directional stage, no overflow, no console errors
• ✓It is the wrong fish — the painting on disk is a goldfish, which is a pet, and nobody scales a goldfish. This stage is waiting on a painted ปลาทู, and until then it says "a fish with its scales off" rather than "ready to cook"planned

✓ = done · ☐ = planned. Every game is built one step at a time like this.
