sweep

sexpgpu sweep <file.sx> <sweep> enumerates a declared defsweep and runs its points in order, each as a run in this process.

$ sexpgpu sweep my-run.sx lr-scan --dry-run
0  lr=0.5  my-run-lr=0.5
1  lr=0.25  my-run-lr=0.25

flag	meaning
--dry-run	print the enumeration (index, selection, slug) on standard output and run nothing
--only N	run one point; past the end exits 2
--set k=v	pin a knob for every point; pinning an axis of the sweep exits 2
--variant V	the base variant, when the sweep names none
--diagnostics G	the diagnostics selection of every point

• Each point's line goes to standard error as it starts; a table of point, slug, final evaluation (eval/loss when reported) and metrics location closes the sweep.
• --set and --variant appear in every point's line and slug.
• Every selection is compiled and checked before it runs.
• The first failure stops the sweep and names the point.
• A JSONL metrics target and a status file each get -<index> before the extension, one per point: status.json becomes status-0.json, status-1.json.
• A sweep the file does not declare exits 2.
