nx_oeuvre_graph.nx

nx_oeuvre_graph.nx -- SREACH-OEUVRE O1: the DV2.0 MANY-TO-MANY information graph foundation, authored into the SOVEREIGN STORE (knowledge/store/oeuvre-) via nx_seg_store. This is the read-side schema of the "an agent CREATES a product in a PLACE / a person VIEWS|BUYS a product in a PLACE" model (operator, 2026-06-13): no privileged root -- ANY node (agent person/org, work, franchise, character, medium, place) is a first-class search anchor, and every relationship is many-to-many (the whole point: search "zatoichi" -> its MANY feature films, like Google's knowledge panel but sovereign + ground-up). HONEST SCOPE (rule 5, no-overclaim): O1 proves the SCHEMA + the M:N TRAVERSAL MECHANISM on a SEEDED FIXTURE (every hub source-anchor = "seed:fixture"). The LIVE enumeration of a real producer's true body-of-work from wikidata/wikipedia/Commons is authored-by-organ in O2 (resolver) + O3 (enumerator) -- NOT claimed here. This gate is the floor everything founds on. IDEMPOTENT (rule 10): a record is written only if absent-or-changed; then EVERY record is read back and the M:N traversals are recomputed FROM THE STORE -> verdict GREEN only when the store actually holds + traverses what we intended. Negative control (a bogus link, and the screwdriver NOT in a film series) MUST come back absent, so the gate cannot false-green.
