Learn by moving things

DSpark's first idea, interactive. Two replies fit after 'Thanks!': 'of course' and 'no problem'. Flip a blind parallel drafter (reaches for the same word and crossbreeds into 'of problem') against DSpark's sequential head, which lets position two see position one and adds a small bias so the words always agree, at the same speed.

DSpark's second idea, interactive. Each drafted word carries a confidence of surviving the check; multiply them into a running survival that only falls. Change the server load to move the 'worth a check' line and watch the cut move: heavier load raises the bar and stops sooner, so the target never spends its scarce capacity on words that were going to be rejected.

The whole DSpark cycle end to end, no clicking. A parallel pass drafts a block, a confidence score is attached to each token, the running survival product falls, and DSpark stops early and drops the tail the moment the numbers stop being worth checking. Then the target verifies the kept prefix in one pass, accepts the correct part, corrects the first miss, and the correction seeds the next round.
