+## Phase 22 Patch-Series Mirror Invariant
+
+Phase 22 verified that the LocalAI on-disk paged patch series still reconstructs
+the canonical llama.cpp fork tree after patch `0055`.
+
+Method:
+
+- Create a fresh worktree at Makefile pin
+  `0ed235ea2c17a19fc8238668653946721ed136fd`.
+- Apply every `backend/cpp/llama-cpp-localai-paged/patches/paged/0*.patch` with
+  strict `git apply`, matching the LocalAI build path.
+- Stage the result and compare `git write-tree` with the fork branch HEAD tree.
+
+Result:
+
+```text

+fork_tree=5bdbf8ea3d750fe6fa1f85175fd6357d36222edb
+```
+
+Decision:
+
+- The patch series is drift-free against fork branch `localai-paged` at
+  `fb9402661 feat(server): trace speculative batch shapes`.

+## Latest mirror check

+Phase 22 re-verified the mirror invariant after adding patch `0055`:
+
+```text
+base=0ed235ea2c17a19fc8238668653946721ed136fd

+```
+
+The check used a fresh worktree at `LLAMA_VERSION`, applied every
+`patches/paged/0*.patch` with strict `git apply`, staged the result, and compared
+`git write-tree` to canonical fork branch `localai-paged` at
+`fb9402661 feat(server): trace speculative batch shapes`.

 ## Status
 
 - **0001 vendor manager — DONE.** Applies clean to the pin; builds into `libllama`.
