Get Signum Rgg Archive

Per-day SIGNUM_RGG colour state for the full universe, from the daily archive.

Thin wrapper over /backtesting/daily-snapshots/{date} that returns only its signum_rgg block, split into summary (counts, breadth, top lists) and the full by_symbol map (colour, signed score, ADX/DI, days_in_color, flipped_at, price, hl_symbol join key). Available for every archived day (the block has been stored since 2026-03-02).

computed_from (present on days archived from 2026-09-09) is the last COMPLETED daily bar the colours were read from; the archive is built at 20:00 UTC, so a day's block carries the colours completed through the previous UTC close. Days before that were archived with the forming bar included. Same auth gate as daily-snapshots. 404 (with Retry-After while today's build is pending) when the day has no snapshot, and 404 when a snapshot exists but predates the SIGNUM block.
