v1.2 keeps the same frozen 11,813-issue snapshot and adds SOLUTION_INDEX.csv plus solution_status/solution_reference pointers in ISSUE_INDEX.csv. The solution layer is intentionally narrow: 11 issues with concrete resolution/fix evidence or an explicit current-verification gate (6 resolved/closure-ready, 5 fix candidates needing verification). No solution is inferred for unresolved rows. Includes refreshed ZIP and compressed ISSUE_INDEX.csv downloads.
