ECR-000003 EXP-001 Repair Report

Overall Status

READY_AFTER_P001D_RERUN

P001D Topology Repair

Check	Status	Notes
baseline terminal path identified	PASS	Baseline `P001A` includes explicit `N6 -> END` termination path
missing terminal edge restored	PASS	`P001D` now includes explicit `N6 -> END`
topology otherwise preserved	PASS	Only neutral pass-through expansion remains as the intended structural difference
neutral pass-through nodes remain neutral	PASS	`N1a`, `N1b`, `N1c`, `N5a`, `N5b`, and `N5c` remain pass-through states
packet version updated	PASS	`packet_version: 1.1` and refinement reason added

Remaining Blocking Issues

Corrected primary comparison still requires new P001D responses for GPT, Claude, and Gemini using packet version 1.1.

Required Reruns
