#181 parked per user decision (the flicker survived the 7-fix ladder; every fix individually verified and standing). ISSUES #181 carries the shipped-commit list, the evidence-backed eliminations, and the four still-open leads (top: capture a clean frame pair at THE USER'S pose - never done). New handoff docs/research/2026-07-06-177-stairs-pickup-handoff.md: the stair-cell admission miss (0x0178/0x0182/0x0183), the existing Issue176177 replay scenarios as the entry point, the 0x0181 sliver adjacency lead, the lighting DO-NOT-REOPEN, and the companion prompt. Render digest re-bannered.
