-This command is idempotent and safe to retry after partial failures:
-1. Validates all issues exist and no self-merge
-2. Migrates all dependencies from sources to target (skips if already exist)
-3. Updates text references in all issue descriptions/notes
-4. Closes source issues with reason 'Merged into bd-X' (skips if already closed)
-Example:
-  bd merge bd-42 bd-43 --into bd-41
-  bd merge bd-10 bd-11 bd-12 --into bd-10 --dry-run`,
+	Use:   "merge <source-ids...> --into <target-id> | merge <output> <base> <left> <right>",
+	Short: "Merge duplicate issues or perform 3-way JSONL merge",
+	Long: `Two modes of operation:
+
+1. Duplicate issue merge (--into flag):
+   bd merge <source-id...> --into <target-id>
+   Consolidates duplicate issues into a single target issue.
+
+2. Git 3-way merge (4 positional args, no --into):
+   bd merge <output> <base> <left> <right>
+   Performs intelligent field-level JSONL merging for git merge driver.
+
+Git merge mode implements:
+- Dependencies merged with union + dedup
+- Timestamps use max(left, right)
+- Status/priority use 3-way comparison
+- Detects deleted-vs-modified conflicts
