+# L1-watcher aliases — settings.json machine name → Tooling Прил. Н search substring.
+#
+# Purpose: settings.json lists plugins under their marketplace machine name
+# (e.g. "frontend-design@claude-plugins-official"), while Tooling Прил. Н
+# describes them under a human/group name (e.g. "Frontend Design plugin",
+# "Trail of Bits Skills"). Without this map the watcher false-positives.
+#
+# Format: <settings_name>=<substring to find in Tooling text>
+# Lines starting with # and blank lines are ignored. First "=" splits key/value.
+#
+# When adding a new plugin to ~/.claude/settings.json: prefer formalizing it
+# under its own #NN row in Tooling §3.3 (Pravila §16.4 — это требует Tooling-
+# номер). Only add an alias here when the plugin is intentionally documented
+# as part of a group (e.g. Trail of Bits Skills #39 = 8 sub-plugins).
