-# Incomplete ART CI scaffold — not maintainable as a gated workflow:
-# - Matrix include used `shard: [1..8]`, which expands to job name
-#   "Shard Array/8" (failure run 19399502401, Nov 2025).
-# - Job depends on `make lean-offline`, which is workflow_dispatch-only
-#   after #194 (unachievable cold-cache path on GitHub-hosted runners).
-# - Workflow references missing tools: art_aggregate.py, art_dashboard.py,
-#   art_gates.py; art_runner.py does not implement the --shard/--output CLI.
-# Kept as workflow_dispatch-only so it can be revived without gating the
-# main inventory. Push-gated bench Lean remains lean-morph / swebench smoke.
+# CI-sized ART smoke: deterministic Python suite (no Lean offline, no missing
+# aggregate/dashboard tools). Full sharded bench remains available via
+# workflow_dispatch with --full.
