+# ECHO Vault Marker
+
+This file marks the vault as bootstrapped by the **echo-memory plugin** and records its schema version. The plugin's loading procedure GETs this file as its "is this vault set up?" probe; a `404` triggers a fresh bootstrap.
+
+- `schema_version` — bumped by the plugin when the vault layout changes; a mismatch is the hook for a migration pass (see `references/bootstrap.md`).
+- Do not hand-edit. The plugin owns this file.
