-No PCRE2, Python, Go, Rust, .NET, Java or legacy-PCRE runtime is included in
-version 0.1.0.
+The explicit offline PCRE2 build is documented in `docs/ENGINE_BUILDS.md`.
+PCRE2 source is not vendored: the gate accepts only the pinned, clean official
+10.47 checkout and Emscripten 6.0.4 compiler. Generated staging is ignored; the
+verified runtime files, deterministic metadata, checksums and exact licence are
+installed under `public/engines/pcre2/` and included in the application source
+and build.

+The v0.2.0 release includes PCRE2. Python, Go, Rust, .NET, Java and legacy PCRE
+remain unimplemented. The v0.1.0 release remains available under its historical
+tag and artifact coordinates. A future public artifact must bump package,
+manifest, tag and source identity together; it must not reuse `v0.2.0`.
