research: sector-resid deep test (deepen shallow + one masked PASS/FAIL)

Terminal follow-up for Task 1: detect/refetch shallow two-tier symbols and sector
ETFs at 5000d, regenerate manifest, run ONE liquid-1500 harness with era split, grade
mom_12_1_sector_resid mechanically. Bundled as run_tier1_macbook.sh --sector-resid-deep.
