+## Latest runtime installation evidence — 2026-10-19 review
+
+Custodian's `docs/changes/netkingdom-target-2026-10-17/native-runtime-install-r3/execution-receipt.json`
+supersedes the older not-installed runtime narrative: complete artifact
+`f59959b605a51abd2901becde14e7abd852c2bd3f848004b51d250d1cb81af6d`
+is installed on Railiance and its offline rein/Glas/Claude startup is verified.
+Full digest matched after rehearsal, durable receipt preceded cleanup, and
+process quiescence was verified. The failed revision-2 rehearsal remains
+historical evidence. This revision-3 receipt has zero model calls and no
+credential or owner-configuration reads; it does not prove active credentials,
+profile readiness or isolation of the actual Custodian interactive assignment.
