Bug fixes
Out of scope
6 ran_indexer_failed markets remain — 4 fficd-001 election markets ($153M-$1.5B) and 2 fficd-003 top markets ($174M, $269M). Phase 3 will recover the 2 fficd-003 markets via Polygonscan logs API. Election markets deferred to future revision.
Files
After merge
Branch stays open for Phase 3 (Polygonscan logs API for fficd-003 indexer-failed markets). Phase 3 will be appended to this branch and PR.
