First generation attempt, 2026-10-08: helper copy command used paths relative to USS while workdir was134, so render_seed.py was not created. generate_fields.py stopped at ModuleNotFoundError after retaining S1-U0 raw field, trace and generation metadata. No training/model changed. Corrected helper source/target to absolute paths; restart checks existing JSON bytes for exact equality. This was a local orchestration error, not an artifact or model validation failure.
