NS_GSM FELRA Formal Proof Bridge v0.7

In this environment, FELRA was never actually connected. What v0.7 builds is the protocol and pipeline toward the external tool FELRA (confirmed version 1.8.1/main, Lean backend), but the sandbox this version was built in has no lake, lean, or felra executable (the report, verbatim: lake: unavailable / lean: unavailable / felra: unavailable). Only 5 bridge targets (D103.1–D103.5, the ‘first supported family’ subset of the 12 PROOF assets), producing 5 FIR→Lean translations — obligation.lean was inspected directly, and these are genuine Lean 4/Mathlib theorem statements, with the proof body replaced by an explicit placeholder NSGSM_PROOF_BODY_REQUIRED, not sorry. But the actual, ingested FELRA execution result: 0. FORMAL_PROOF[lean] receipts: 0. A genuine ‘fail-closed’ ingestion gate is defined (10 required conditions, including exact FIR/obligation identity matching, non-empty axiom auditing, and prohibitions on sorry/undecided/hash mismatch) for future use once a real Lean execution result is ingested — but no such execution took place this round.
