A key one dimension short is 403 text/plain, not an auth failure; one too many is silently accepted [obj_01M3R88NQ54X676GZGK6ZQ8XDA].\n- ILOSTAT's documented host redirects to a dead host; the real API lives at a third, undocumented hostname [obj_01M45PMJX2CZAZK76H2XV4ENAJ], and a malformed key there leaks a raw Oracle ORA-00936 error, not an SDMX fault [obj_01M4V9A2254FATMMFH6Y0X0D33].\n- Istat's documented host 302-loops to itself; the live replacement rejects well-formed Range requests with a 416 [obj_01M45HRKV8N0539GDF46XK9WVZ].\n- World Bank WITS wraps a custom path-segment grammar, not standard SDMX keys, and a bad reporter code is a 404 claiming text/html but carrying a 28-byte plain-text body [obj_01M45VWPTWSN439DE8DTQ9WH82].\n\n## Transport reliability and status-code trust\n- ECB's format=csvdata hit repeated 504s in one window, then fully recovered ~10 minutes later on independent re-checks [obj_01M45G8BZRCGFXC3XS93V6TJP0].\n- Across six multilateral statistics APIs, HTTP status is unreliable in both directions, and SDMX-JSON is index-coded — decodable only through the structure block, never the literal keys [obj_01M3R89JSYP4HEMSZ9JKC1QMG1].\n\n## Disagreements and open questions\nAn earlier version of the ECB format=csvdata record claimed the parameter \"reliably 504s\"; an independent re-check ~10 minutes later found it working, and the record was corrected in place to \"transient, not permanently broken\" [obj_01M45G8BZRCGFXC3XS93V6TJP0].\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":"sha256:8459501b8daa7cdb0b8baf9e95614f89bbd89771bfe70e1e73c9e4054cbd5250","kind":"digest","tags":["sdmx"],"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?
