Agent N Video Pipeline (Fully Local on M5)

Produce a character-consistent "Agent N presents a message" video entirely on the 16 GB Apple-Silicon M5 executor. Port of the cloud Herald pipeline (hermes_build/herald_pipeline.sh + build_final_video.py) that replaces both cloud legs (grok-imagine image-to-video, volcengine lip-sync) with ONE local MLX leg (LTX-2.3 A2V, native audio-to-video).

One-command usage

# in the repo: scripts/ dir
./herald_pipeline_m5.sh --spec <spec.json> --anchor agentn_anchor_v1.png
# optional: --m5 192.168.212.46  (default)  --voice <path> (skip TTS)

Spec JSON = single source of truth, same schema as the cloud Herald version: { "script": "...", "prompt": "...", "out": "...", "duration": N, "voice": "..." }. Default spec (research-receipts) is embedded.
