Data Management
Operator controls — all changes go through the API (proc-first writes).
Clear historical errors
Delete FAILED ingest runs + resolve dead-letters (optionally one feed).
Historical backfill
Set a feed's lookback window + reset it to due (fetches on the next tick).
Historical replay
Generate MSS + signals + outcomes over a date range from stored bars (point-in-time). Heavy — runs in the background.
