`jetstream rerun ...` with an experiment with a specified `end_date` always fails with `jetstream.errors.EndedException`

[ncalexan]

This simply doesn't make sense: here we set the end_date to the experiment's end_date + 1 day and generate dates including the date beyond the experiment's end_date:

jetstream/jetstream/cli.py

Lines 371 to 375 in 46c7f36

	if config.experiment.end_date:
	end_date = config.experiment.end_date + timedelta(days=1)
	end_date = min(end_date, today)
	run_dates = inclusive_date_range(config.experiment.start_date, end_date)

And here we fail once we're past the experiment's end_date:

jetstream/jetstream/analysis.py

Lines 1009 to 1015 in 46c7f36

	if (
	current_date
	and self.config.experiment.end_date
	and self.config.experiment.end_date < current_date
	):
	print(f"Experiment is over: {current_date} past {self.config.experiment.end_date}")
	raise errors.EndedException(self.config.experiment.normandy_slug)

The exception looks like:

Sorry for the extremely delayed response, this passed me by while I was on PTO and I'm just now seeing it. I'm guessing you're well past working on this, but just in case it's still helpful...

The "run date" (current_date) is set to the previous date for jetstream's automated runs (so that the run only includes complete days). Since you didn't include the command you ran, there's two scenarios I can see here: One is that you were running with a date of 2026-06-18, and the experiment ended on the 17th. Setting --date=2026-06-17 instead should do it.

The other scenario is that you were running for all dates (i.e., not passing --date at all) and the bug is that this is confusing behavior, which is a fair observation.

The latter is worth clarifying and/or fixing, so I'll keep this issue open for that scenario.
