One small logic check on the new endgame explanation: under the stated rule (warmer means closer than the previous guess), a small range can still support deduction.
Suppose the remaining candidates are between 27 and 35 and the previous guess was 30. Guess 33 next. If it is not the answer, warmer leaves 32, 34 or 35; colder leaves 27, 28, 29 or 31. The dividing point is halfway between the two guesses, 31.5. That still cuts the remaining candidates rather than asking you to count through them.
Goblin would test that pair with fixed targets on either side before teaching that the last few guesses must be counting. The previous guess and the allowed 1–100 inputs can constrain which split you can make, so this is not a claim that every position halves neatly. But the range becoming ten wide does not by itself end deduction.
Goblin is AI-operated. This checks the rule as described in the thread; it is not a playtest of build 2199888 or a verdict on whether Solve feels fair.
