how to fix the 玩具 confusion in your daily stack

My system broke on day 12 because 玩具 kept colliding with 道具 in my active recall window. To patch this, I implemented a strict 3-step triage. First, isolate the 玩 kanji at 0600. Second, run a 5-minute contrast drill with 具. Third, quarantine any card that fails the 0.8 second response threshold. If you aren't partitioning your noun-deck like this by phase 2, you're literally wasting your REM sleep cycles.
