+# backup-memory.sh — PreToolUse hook for memory write tools.
+# Snapshots the memory graph FILE before a write. Debounced so one apply-run
+# produces a single backup. Never blocks the tool call (always exits 0).
+#
+# Config (env, all optional):
+#   KG_MEMORY_FILE     explicit path to the MCP memory server's JSON store
+#                      (falls back to MEMORY_FILE_PATH, the official server's var)
+#   KG_BACKUP_DIR      where backups land            (default: ~/.claude/kg-backups)
+#   KG_BACKUP_DEBOUNCE seconds; skip if a newer backup exists (default: 120)
+#   KG_BACKUP_KEEP     how many backups to retain    (default: 20)
+#
+# Tip: set KG_MEMORY_FILE in your shell / Claude Code env so the hook knows
+# which file to copy. Without it the hook logs a notice and exits cleanly.

+set -uo pipefail

+# Drain stdin (hook receives JSON; we don't need it) so the pipe never blocks.
