+## Locked Vault Workflow
+
+User story:
+
+- When the current page has a login form but KeePassGO is locked, the browser
+  must still make that state visible on the page and in the popup.
+- Unlocking KeePassGO should not require the user to reopen the popup multiple
+  times or reload the page before the extension becomes usable again.
+
+Expected behavior:
+
+- The popup shows a locked-state message instead of silently falling back to
+  "no matches."
+- The inline page affordance stays visible on login forms while KeePassGO is
+  locked and tells the user to unlock the vault.
+- After the vault is unlocked, the extension rechecks the page automatically
+  and turns the locked affordance back into live matches without requiring a
+  page reload.
