Quarantine contract

Existing row. Preserve the raw archive and current partition by hash. Do not silently drop, move, or replace the row in an identity-bound replay.

Future ingest. Reject every split or dividend whose value is non-finite or non-positive before writing the executable corporate-action lake.

Unlock. Obtain an issuer/depositary or corrected-vendor record establishing the ADS ex-date, knowable-at timestamp, and net USD cash amount. Then create a new versioned corrected lake and replay environment; retain this failed attempt.

Every figure above is read from /glassbox/sharadar_zero_dividend_quarantine.json, the artifact the engine wrote. Nothing on this page is typed by hand: the page is generated from that file, so a figure that moves in the artifact moves here and a figure that is not in the artifact cannot appear here at all.
