Mognitio 1.4.0

Mognitio 1.4.0 extends the experimental Mognitio-written compiler with a shared structural frontend for mgnc parse and mgnc build.

• Parse complete compiler sources, including the fixed 1.3.0 corpus and all 57 files of the 1.4.0 compiler itself.
• Preserve the 1.3 native build profile and diagnostics through the shared frontend. Comparison arguments such as choose(a < 2, 3 > (1)) retain their previous behavior.
• Validate corrected combined workloads, declaration classification, source positions, failure handling, native execution and the accepted resource budgets.

The normal mgn compiler and mognitio-lsp retain their existing backend. The experimental mgnc is built explicitly from compiler/mgnc using the pinned 1.2.0 seed; it is not installed by the Debian package or offline bundle. Parsing the compiler's own sources does not establish self-compilation or general 1.x native compilation.

See the compiler guide, review and acceptance evidence, and distribution instructions.

Distribution targets Linux amd64 on Ubuntu 24.04 and 26.04. Verify the signed manifest against the independently reviewed public key before installing an offline bundle. The signature authenticates the manifest, which contains the checksums of the archive and Debian package.

A pre-existing normal-compiler limitation remains: an unused imported witness can report an internal error; the exercised witness control succeeds. Reproduction and seed comparison are retained. The VS Code extension has its own version and compatibility policy and is not part of this release.
