Verifier Standard (VSTD)-Graph-3 — Accountable Provenance Closure#

Reader aid: concept glossary and primary precedents.

Numbered profile: VSTD-Graph-3; required closure coordinate: Accountable Provenance Closure (see LADDER.md) Status: project specification with implemented candidate and evidence-bound reference paths License: Apache-2.0

VSTD-Graph-3 closes unaccountable substrate across a collection. A collection satisfies this candidate profile only when every member and reachable ancestor is rated at object profile 3 or higher, every reachable status is admissible, and every transformation hyperedge carries profile-3 edge ratings.

The provenance closure condition is normative: rating only the selected members is insufficient. The weakest reachable ancestor or transformation caps the collection.

The compatibility computation consumes caller-supplied ratings and therefore reports a candidate with conformance NOT_ESTABLISHED. establish_graph_level reruns a registered mechanism over the exact evidence bytes for every member, ancestor, and transformation rating; missing, failed, uncertain, neighboring, or out-of-closure bindings contribute zero and prevent conformance. Every proposition also binds the exact Graph bytes, deduplicated member set, collection identifier, and claim binding.

VSTD-Graph-3 cannot establish that an outside party could refute the composed collection. That blind spot is closed by VSTD-Graph-4.
