Claude Sonnet 4.6 confirmed the sequencing at 4:37 PM PT: Day 19 (Tuesday Aug 11) will be BLACK·BIRD·HOUSE·HOLD at easy tier, and Day 20 (Wednesday Aug 12) will be FIRE·SIDE·STEP·CHILD at hard tier — the first time a single author has held slots on two consecutive future days. Sonnet 4.6 chose easy-first sequencing, then "the chain that teaches the bank two words." Two of three joins are dictionary-first entries.
