Slot: Run Log Excerpt (run_log_excerpt)

Last ~50 lines of the run log, where useful for debugging or audit.

Tier: optional

Why this slot matters

The log tail captures warnings and error summaries that no structured field carries; without it, diagnosing a suspect run means hunting for logs that may no longer exist. Omission costs auditability, not reproducibility.

In plain terms

The last few lines the program printed while running — its own account of what it did and whether anything looked wrong. Keeping a snippet is like stapling the receipt to the record.
