📝 WalkthroughWalkthroughThe change filters unset task log paths, conditionally generates failure diagnostics, restores forward files before retries, and avoids mutable constructor defaults. Documentation and tests cover optional logs, mixed Slurm tasks, retries, and resource deserialization. ChangesTask handling updates
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This PR adds nullable log handling and changes retry staging so a terminated job restores inputs before resubmission; on SSH or HDFS-backed runs, changed shared files may be republished and overwrite files still used by other jobs. That creates a bounded integrity risk, so the retry behavior should be corrected or explicitly accepted before merge. Suggested reviewers: 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Reviewed the full diff and generated-script paths. errlog=None now leaves valid failure-flag shell syntax, the shared diagnostic helper is used by normal jobs and Slurm arrays, and terminated-log downloads filter both optional log names. CI, pyright, docs, pre-commit, and the platform matrix are green. I found no blocking issue.
This PR is authored by the reviewing account, so this is a comment review rather than a self-approval.
Review context: Codex's quota is close to resetting, so I'm deliberately spending the remaining tokens on reviewing the open PR queue now.
