+# user-engine accepted v0.8 checker migration
+
+This owner applies GH-WP-0004-T11's post-flip migration to the confirmed
+accepted NetKingdom v0.8 cut, immutable accepted-1 artifact SHA256
+3d8298560069ef471fba28d2b1245fb2309328f231dad1a667cdf0ce5a5a7c8b.
+The checker names that artifact and its local scope in every run. INTENT
+frontmatter remains authoritative and the sidecar remains derived; a
+contradiction is a finding, never hidden by choosing one form. No declaration
+acquires a standard version.
+
+The pin detector follows OpsWarden's A12 r3 reference semantics: standard and
+companion identity values (including nested lists), version-bearing paths and
+standard/companion version keys are pins; unrelated intent/schema/spec versions
+and bare prose provenance are not. Existing local Tooling/contact and capability
+detectors remain in place. Historical version strings in negative fixtures are
+retained. This source migration grants no native capability or runtime authority.
+
+Validation includes the existing local declaration/contact suite and the same
+12-case pin/provenance corpus across all four assigned owners, with exact
+accepted-artifact and scope assertions. The local test counts and staged source
+digests are retained in the coordinating Custodian evidence receipt. Standalone
+checker runs continue to inspect only this repository; no estate-wide compliance
+claim or novel declaration is produced.
