+# scrum — find gaps in current work-in-progress, push to KB.
+#
+# Usage:
+#   ./scrum                    auto-bundle current diff vs origin/main, auto-label
+#   ./scrum my_label           same, with explicit label
+#   ./scrum --staged           bundle staged-only diff (pre-commit check)
+#   ./scrum --since=COMMIT     bundle from a specific commit
+#
+# Output:
+#   findings  → data/_kb/scrum_findings.jsonl  (one row per scrum run, KB-queryable)
+#   verdicts  → reports/scrum/_evidence/$(date +%Y-%m-%d)/verdicts/<label>_*.md
+#
+# This is a TOOL J runs to find gaps. Findings flow to the KB. The KB
+# informs how WE work on the code. Findings DO NOT auto-flow into
+# architecture or design docs — that's J's call after reading them.
+#
+# Cloud models are used here BY DESIGN (3-lineage cross-review needs
+# distinct training corpora). This is dev tooling, not the runtime
+# hot path — PRD line 70 applies to customer requests, not to J's
+# dev tools.
