1// nx_asset_exceed_gate.nx -- UNIVERSAL ORGANIZATION TOOLING arc, R7: the MEASURED exceed referee.
2//
3// This is the capstone the operator's directive demands: "S-class measured-EXCEED, referee-measured,
4// NEVER self-scored."  It turns "we built a content-addressed asset/knowledge IMS (R0-R5)" into "we
5// have a PROVEN S-class-exceed IMS" -- by GRADING the DAM+KM inventory head-to-head against incumbent
6// DAM (Adobe AEM / Bynder), KM (Notion / Confluence) and consumer media (Google Photos) on the axes
7// from the sovereign-fetched research (org_research.tsv), and PROVING every EXCEEDS claim by RUNNING
8// the real R0/R1/R2 organs.  No cell is true without a passing run.
9//
10// TWO HALVES, both honest (mirrors nx_library_exceed's discipline):
11//   A) DATA-DRIVEN CENSUS  -- the head-to-head scorecard lives in the NATIVE seg_store (nx_native_config),
12//      authored by census_seed (no TSV); counts EXCEEDS / PARITY / BEHIND.  Honest self-assessment, NOT the claim.
13//   B) PROOF-BY-RUN of the six EXCEEDS axes against the REAL organs:
14//        P1 AX06 sovereignty   deterministic + order-independent CID (same bytes -> same id; no clock/
15//                              RNG/surrogate key) via nx_asset_record (ar_cid / ar_encode)
16//        P2 AX01 integrity     flip one byte of the record -> the CID CHANGES (tamper-evident)
17//        P3 AX02 dedup         CID-keyed catalog vs a filename baseline: identical bytes -> count 1
18//                              while the filename baseline counts 2 (nx_asset_catalog cat_ingest/count)
19//        P4 AX03 unified       image + video + doc in ONE catalog -> count 3, each byte-faithful + typed
20//        P5 AX04 provenance    ed25519 credential bound to the record CID verifies ALLOW (nx_asset_provenance)
21//        P6 AX05 no-link-rot   store, then resolve PURELY by content id offline -> byte-faithful + decodes
22//   NO-FABRICATION negative controls (must hold, proving the metric is not rigged):
23//        N1 distinct records -> DISTINCT CIDs, counted as 2 (a collision/false-merge would FAIL)
24//        N2 a forged (wrong-key) provenance credential -> REJECT (what a plain hash can't catch)
25//        N3 a tampered assertion -> REJECT
26//        N4 an honest-BEHIND axis (AX09 scale) MUST read BEHIND in the census (liar-kill on overclaim)
27//        N5 CENSUS-TIE: #EXCEEDS rows == #proofs that PASSED -- you cannot claim more exceed than proven
28//
29//   VERDICT GREEN iff census parsed AND all six proofs passed AND every neg-control held.  No hardware
30//   writes, no network, no production side effects (Rule 26).  Verdict appended to
31//   knowledge/status/asset_exceed_gate.log (additive law #13).
32//   expect_exit: 0   license_tier: ORIGINAL
