+# Sync note
+
+This Gitea repository is a **default-branch source snapshot** of:
+https://github.com/TideSec/TscanPlus
+
+## What is on `main`
+- README / docs / skill files
+- screenshots and demo media under `images/`
+- `SYNC_NOTE.md` (this file)
+
+## What is in Releases
+Large prebuilt binaries from upstream were **not** stored in git history, to avoid reverse-proxy / size limits:
+- `TscanPlus-v3.3.8/*` (GUI releases)
+- `TscanClient-v2.9.5/*` (client builds)
+- `soft/*` (bundled tools)
+
+See the latest Release assets on this repo for downloadable packages.
+
+## Not a full mirror
+- No upstream git history
+- No non-default branches/tags
+- Upstream HEAD at import time: `main` (`f405040e50b71cf8d210e377f8bb7069fb883577` via ls-remote)
