+# reset-sindra-stores.sh — wipe ratatoskr's Bifrost provider stores (memory +
+# affect/persona for the single-tenant Tier-3 agent, sindra) and restart the
+# combined :8392 provider empty.
+#
+# Usage:
+#   scripts/reset-sindra-stores.sh          # wipe, keep ONE rolling backup (default)
+#   scripts/reset-sindra-stores.sh --hard   # wipe with NO backup (zero-trace)
+#
+# The rolling backup (db-reset-backup/, gitignored via *.db*) is overwritten
+# every run — it never accumulates; it's a one-level undo, nothing more.
+#
+# Why stop the provider first: the combined provider holds the SQLite files open
+# (WAL) and caches state in memory, so an out-of-band file move without a restart
+# would be shadowed. Stop -> move -> restart lets it recreate empty schema
+# (CREATE TABLE IF NOT EXISTS on open).
