BIT-LMIND-TSS-TLTH-BRIDGE-001-REL-001: F2 Bounded Clean-Room Differential Release and F2-to-F2R1 Fail-Closed DPC Record

This independent-research archival release preserves the exact-byte publication lineage of BIT-LMIND-TSS-TLTH-BRIDGE-001 through F0, F1 and F2, together with its DPC documents, controlled release packages, manifests, indexes, certificates and receipts. Under the frozen F2 corpus and declared pair-relation specification, separately implemented static checkers completed five rounds with 470/470 baseline equality relations and all 25/25 predeclared diagnostic divergence relations, yielding 495/495 compliance with the expected pair relations. The exact F2 verdict is PASS_WITH_SCOPE_BRIDGE_F2_INDEPENDENT_CLEAN_ROOM_DIFFERENTIAL_ONLY. The prospective F2-to-F2R1 DPC failed closed because the exact TLTH-MATH-F5 machine-manifest preimage was unavailable and custody of its referenced raw payloads was 0/30. No F2R1 authorization was issued; F2R1 remains NOT_AUTHORIZED_NOT_OPENED. This is bounded implementation evidence only. The release performs no certificate reuse, corpus mutation, HOLD discharge, semantic execution, state update or inverse inference and establishes no empirical validity, person-level conclusion, authority or external effect.
