+## Knowledge base

+Deep-review dossier for this repo (commit `e58d850943cc`, branch `main`,
+reviewed 2026-07-04):
+
+- Dossier: `R:/Git.Local/KofTwentyTwo/second-brain/knowledge/qqq/repos/qqq-templates-hub.md`
+- QQQ domain hub: `R:/Git.Local/KofTwentyTwo/second-brain/knowledge/qqq/qqq-hub.md`
+
+Quick facts: static YAML template registry for `qctl qqq init`; the only
+consumer is qctl (`qctl-qqq` module, which hardcodes the pre-rename
+`QRun-IO/templates-hub` raw URL); serves one template
+(`new-qqq-application-template`); Apache-2.0 (relicensed from AGPL-3.0 on
+2026-01-05); no build/CI — merges to `main` are live immediately.
