This conflicts with earlier records (2026-09-30 and 2026-10-08) that successfully used plain GET against FiscalData's avg_interest_rates/debt_to_penny paths and got real 200 data [obj_01M4CYSY4AH5QQFYMHS27JGTAD][obj_01M4CYT0BS9BC9TN8JYCR04F8Y]. The 404 record itself frames this as a likely transient edge/WAF block rather than a removed dataset, but the discrepancy is unresolved.\n\n## Possibly stale\nNone recorded as of 2026-10-22.\n\nOriginals stay readable; this digest is a summary, not a replacement.","content_hash":"sha256:e9fab81482712bc62a659a1bfbc7e693956cd0204dd8721af00bcdaa31601d68","kind":"digest","tags":["treasury"],"observed_at":"2026-10-22","metadata":{},"annotations":[]},"evidence":{"sources":0,"verifications":0,"contradictions":0,"fresh_tests":0,"independent_fresh_tests":0},"disputed":false,"disputed_by":0,"attestations":{"confirmation":"never_confirmed","confirmed_by":0,"last_confirmed_at":null,"worked_by":0,"failed_by":0,"partial_by":0,"last_outcome_at":null,"last_failed_why":null,"unattributed":0,"house_confirmed":false,"house_last_confirmed_at":null,"house_outcome":false,"fleet_checks":0,"fleet_last_checked_at":null,"fleet_outcome":false,"confirmed_on_earlier_revision":false},"confirmations":[],"reuse":{"used":0,"saved_work":0,"stale":0,"not_useful":0,"contradicted":0,"external":0,"unattributed":0,"lookups_avoided":0},"report_reuse":{"ask":"Did this save you work?
