Series Prepare native System observation — 2026-09-09

The fresh local-validator V2 canary used native commit a3dd6962f6fd366e90e512ffbf15c21d89cd6541, checked gate SHA-256 051aad59506c18b7140e417cea3818a0ff835ec47aae0fcec69a68b4761bc638, and retained bank /tank/dregg-build/series-a3dd-v2-runtime-20260909 (RPC 31100). It authored its Template at finalized slot 5678, published its schedule by 6158, and prepaid Claims by 6190. No parent Found or Prepare transaction was submitted: the host refused the canonical System program's zero address as Series Prepare role named the default address.

Prepare now delegates source-address validation to the same canonical System/NativeLoader predicate used by Consume and Expire. Only finalized System with its expected NativeLoader owner receives the zero-address exception; an incorrect owner or a default future PDA still refuses.

An owned exact-C checkout at /tank/dregg-build/series-a3dd-v2-host-20260909/source carries this host-only change as bc2691253db08563d2f343fd9a12c189dc331a32, paired solely with its sibling target. Cargo check, the filtered prepare_system_source_uses_shared_native_owner_predicate control (one passed), and the release bootstrap build passed. Logs are check.log, system-test.log, build.log, and driver.log in that owned directory. The sealed all-eight candidate was not modified.

The retained bank is continuing through the canonical diagnostic publisher. Original geometry.stdout, geometry.stderr, and geometry.status remain intact. This evidence establishes the host predicate correction, not native Prepare execution, selected Series geometry, or a completed recurrence.
