Mirrors guluchen/DistQLDPC#221 (PI plan 2026-11-04): every stem re-tiered by DistQLDPC main 02879a93's yfclab2 baseline, and DistQLDPC's 24 library codes added with the distances DistQLDPC found (or its proven bounds). All files are byte-identical to DistQLDPC's. Moves: BB_288_12_18 and GB_144_12_12 tier2 -> tier1, TN_144_2_13 tier3 -> tier2, TN_250_10_15 tier4 -> tier3, LP_1020_136_16 tier5 -> tier3; tier4 is empty (kept with a .gitkeep). New: 12 HGP_* (Tillich-Zemor), 6 COLOR_* (Bombin-Martin-Delgado; Sahay-Brown), 6 twisted-torus BB_* (Liang-Liu-Song- Chen), credited in NOTICE 2e. Updated data/README.md and tests/test_repository_paths.py. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
AMC_108_6_9, AMC_216_6_12, AMC_330_6_14 -> tier0, AMC_438_6_17 -> tier1, AMC_522_6_20 -> tier2 (PI 2026-11-04), byte-identical to DistQLDPC; credits (Lin-Lim-Kovalev-Pryadko; Mian-Gwilliam-Krastanov) in NOTICE 2e. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Mirrors guluchen/DistQLDPC#221, the PI plan of 2026-11-04. That PR re-tiers every stem by DistQLDPC main 02879a93's yfclab2 baseline and places DistQLDPC's 24 library codes into the tiers. QDistSAT keeps the same 80 stems as DistQLDPC, and all 320 matrix files are byte-identical to DistQLDPC's branch.

HGP_*hypergraph products (Tillich–Zémor; graph descriptions after Brouwer).COLOR_*triangular 6.6.6 color codes (Bombin–Martin-Delgado; Sahay–Brown).BB_*(Liang–Liu–Song–Chen).AMC_*collapsed 4D abelian multi-cycle codes (Lin–Lim–Kovalev–Pryadko; Mian–Gwilliam–Krastanov). These are the codes of DistQLDPC #214, placed by the PI on 2026-11-04: AMC_108_6_9, AMC_216_6_12 and AMC_330_6_14 to tier0, AMC_438_6_17 to tier1, AMC_522_6_20 to tier2.Stems carry only DistQLDPC's own results: a distance with a GF(2)-verified witness, or DistQLDPC's proven bounds for COLOR_1027_1_28to37 and COLOR_2791_1_26to61.
Updated files:
data/README.md(families, tier table, note),NOTICE(2e),tests/test_repository_paths.py(EXPECTED_TIERS).Merge after DistQLDPC#221. If that PR adds the pending lower-bound renames, they will be mirrored here first.
