+# setup-shared-projects.sh
+#
+# Prepare the shared Claude Code projects/ tree used by claude-failover
+# to preserve session resume across account swaps.
+#
+# Creates /home/ubuntu/.claude-projects-shared (if missing), then rewires
+# each account's ~/.claude/projects to point at it. Existing per-account
+# transcripts are merged into the shared tree (rsync -a, no overwrite of
+# newer files).
+#
+# Usage:
+#   scripts/setup-shared-projects.sh [--shared DIR] [--dry-run] \
+#       account_home_1 account_home_2 [account_home_N...]
+#
+# Example:
+#   scripts/setup-shared-projects.sh \
+#       /home/ubuntu/.claude-compte1 \
+#       /home/ubuntu/.claude-compte2
+#
+# Safe to rerun: it never deletes account-private files (credentials,
+# statsig cache, settings). It only touches the `projects/` subdir.
