AGP-MLX N'Ko ASR Bridge

This directory is the first executable bridge between the verified N'Ko ASR model and AGP-MLX. The bridge keeps the acoustic model authoritative. It classifies ASR chunks into anticipation partitions, allows AGP-style correction only for non-stable regimes, and rejects corrections that exceed a bounded edit budget. The edit budget uses both a relative limit and a small absolute floor. This matters for short N'Ko chunks where one missing vowel can be a large relative edit but still a safe local repair. Every correction decision also carries a provisional Graph Kernel-style admissibility witness. That gives each accepted or rejected AGP correction a slice id, graph snapshot hash, policy hash, and 32-hex token so the bridge can be audited before the live kernel service is wired in. Use that document as the authoritative `GO` / `NO-GO` bar for the learned live N'Ko correction path. Large `oracle_guardrail` replay wins are research-valid, but they do not satisfy the learned live ship gate by themselves.
