+ * Pins the web-side replay-identity implementation against KNOWN-GOOD
+ * fixture outputs.
+ *
+ * The backend canonical module ships in PR #343 on a parallel stack;
+ * this branch (stacked on #350 → #342 → #341) does not have that file
+ * available, so the parity check is pinned via fixture literals
+ * computed against the backend algorithm. When both stacks merge to
+ * main, a follow-up direct-import parity test will lock the
+ * cross-implementation invariant at compile time.
+ *
+ * Until then, ANY change to clientReplayIdentity.ts that alters these
+ * literals MUST also bump the scheme version (v1 → v2) and re-pin
+ * fixture values; the backend module shares the v1 algorithm and any
+ * drift would propagate the same way.
