Skill: log_analysis

Analyze a SLURM job log file for failure root-cause attribution and restart decisions using NVRxLogAnalyzer.

Script: scripts/nvrx_logsage.py → attribution/log_analyzer/nvrx_logsage.py

What it does

1. Reads the log file (UTF-8, falls back to latin-1).
2. Splits into per-cycle chunks using chunk_logs_strict (scans for profiling.py:.*Cycle:\s*N markers). Falls back to a single chunk when no markers are found.
3. For each chunk, extracts application errors via return_application_errors (logsage).
4. Classifies each chunk with fast-path pattern matching (training done, SLURM cancelled, preemption, time limit) or calls the LLM via get_proposed_solution_cat.
5. Returns one result tuple per cycle.
