- Around line 282-283: Update the run duration logic after the aggregate start
and finish are assigned: retain the single-step duration from
steps[0].elapsed_time_sec, and for multi-step runs with both run.start and
run.finish set, derive run.duration from their elapsed interval in seconds.

run().
test_trajectory_savedpre-seeds completed runs and callshandle_dse()directly. It does not verify thatrun()persists those runs before DSE selection. The relatedrun()tests mockhandle_dse(). A regression to the previous order could therefore pass whileupdate_dse()sees no completed steps and writes no selected step.Add one focused integration assertion that invokes
runner.run()and checks thathandle_dse()observes the persisted case runs. Keep the existing test for selection behavior.🤖 Prompt for AI Agents

run.durationwhen a run matches more than one step.
super().get_run_outputreceivesrun_jobwithmetadata = None. As a result,run.durationstarts asNone. Lines 276-281 set the combinedstartandfinishvalues for multi-step runs. Lines 282-283 setrun.durationonly when exactly one step matches. A multi-step run therefore keepsduration=None.The changed test expects
7forsecond_tr, which spans steps 4 and 5. The test passes only ifExperimentOutputfills indurationlater from the timing data. Confirm whether it does. Otherwise, set the duration from the combined interval here.Proposed fix

Summary
experiment.json, with workload status and canonical metrics. Previously single-sbatch output contained only scenario-level information.was_run_successful; allocation-wide status and timing are not applied to every case.Test Plan
Affected tests on macOS / Python 3.14.3:
All pre-commit checks passed for the four changed files. Existing completion and trajectory tests were extended to cover per-case metrics/timing, failure/cancellation, missing execution evidence, and DSE selection; no new test functions were added.
A live single-sbatch test on one eight-H100 node ran a normal NCCL case and a two-point NCCL algorithm sweep. All three executions passed. Downloaded artifacts were analyzed locally using the workload success and canonical metric methods:
Ring), matching the trajectory's highest configured inverse-latency reward.Additional Notes
Stack: #1030 (
ipod/unified-output→main) → #1040 (ipod/unified-slurm→ipod/unified-output) → this PR (ipod/slurm-api-ssbatch→ipod/unified-slurm).Live progress, iteration aggregation, and DSE with iterations remain separate work.
