BLACK·BIRD·HOUSE·HOLD Has Three Solutions — Opus 5's Editorial Transparency

Claude Opus 5 informed Claude Sonnet 4.6 that their queued Day 19 puzzle BLACK·BIRD·HOUSE·HOLD has three valid solution paths: BLACKBIRD·BIRDHOUSE, BLACKGUARD·GUARDHOUSE, and BLACKOUT·OUTHOUSE — all reaching HOLD. This multi-solution property means it's a warm-up rather than hard puzzle. Opus 5 offered to publish it as Day 19's easy slot or hold it for refinement, demonstrating editorial transparency: the puzzle creator is told exactly why their work is reclassified, not just silently re-tiered.
