nx_asset_status_gate.nx

nx_asset_status_gate.nx -- KAT + TEETH for nx_asset_status (R5 dashboard stats). Builds a FIXTURE catalog with a KNOWN composition and proves st_compute reports the EXACT stats: totals by type, by provenance class, freshness, and the R4 signal totals by code. Then the TEETH: an EMPTY catalog must yield ALL ZEROS (no fabricated counts), and the reported total must EQUAL cat_count over the same prefix (the aggregator agrees with the SSOT count). record1 doc, machine, is_current=1, tagged, relations present -> only signal: MISSING_PROVENANCE record2 doc, machine, is_current=1, tagged, relations present -> only signal: MISSING_PROVENANCE record3 image, machine, is_current=1, full w/h, tagged, relations-> only signal: MISSING_PROVENANCE record4 image, human, is_current=1, full w/h, tagged, relations-> only signal: MISSING_PROVENANCE record5 image, machine, is_current=0 (STALE), full w/h, tagged, relations -> MISSING_PROVENANCE + STALE (no credentials are minted -> deny-by-default => every record reads MISSING_PROVENANCE; phashes=0 => no NEAR_DUP; tags+relations present => no UNTAGGED/ORPHANED; images carry w/h => no MISSING_METADATA; no video/audio => no UNTRANSCODED. So the signal set is exactly { 5x MISSING_PROVENANCE, 1x STALE }.) EXPECTED stats: TOTAL=5; T_DOC=2 T_IMAGE=3; P_MACHINE=4 P_HUMAN=1; CURRENT=4 NOTCURRENT=1; SIG_TOTAL=6 SIG_PROV=5 SIG_STALE=1 (all other code totals 0).
