Goblin Purrfect Homebrew release 0.1.0-goblin20260911.1 Target: Apple Silicon arm64, macOS 26 Tahoe. Compiler: Homebrew Rust 1.98.0, Apple Command Line Tools 26.5 (clang 21). Canonical source archive pins rustup users to Rust 1.98.1; the formula uses the declared Homebrew Rust dependency. Actual 1.98.0 standard-library copyright/license texts are retained alongside the installed crate notices. The source archive contains no private WP documents, private reconstructed IBM fonts, proprietary WP software or printer drivers. Font admission and license collection reuse python/wp51_tools/package.py. Its approved font distributions and notices are retained; the separately licensed Apache Tika fixture is included only in source tests, not in the bottle. The macOS bottle was built in an isolated, short Homebrew prefix, /Users/adam/g. Homebrew dependency bottles have path-length constraints, so a longer /tmp prefix would otherwise trigger unnecessary dependency source builds. No dependency is force-poured; normal Homebrew architecture/relocation checks and its build sandbox remain enabled. The isolated Homebrew 6.0.22 checkout has one tool-discovery adjustment: when xcode-select selects the installed current Command Line Tools, Xcode discovery does not fall back to the unused older /Applications/Xcode.app. This changes neither compiler nor SDK and is not shipped by the formula. The installed global Homebrew tooling and Xcode app were not patched. Homebrew's bottle JSON can report an inferred Xcode version; the actual build used CLT, not that full Xcode application. Source validation: 204 Rust tests passed, 12 explicit optional tests ignored. Python validation: 24 tests, 2 optional specimen/dependency tests skipped. Installed-package tests exercise synthetic WP no-op roundtrip, LaTeX export, equation translation, terminal exit restoration, mouse selection/deletion, and packaged license/manual presence. Additional PTY tests cover named/inline image delivery, fallback on transfer errors, divider dragging and 8K/16K pane geometry. These are simulated terminal tests, not a claim of testing an actual 16K physical display or satellite link. The executable links only macOS libiconv and libSystem; third-party Homebrew runtime dependencies remain separate packages. The application signature passes codesign verification. Homebrew's generated bottle is classified any_skip_relocation and carries only the tested arm64_tahoe platform tag. The original source formula's template in the immutable source archive is supplemented by the exact released goblin-purrfect.rb beside this file. The final recipe copies (does not move) standard-library notices from the Rust dependency and includes the existing manual page. These are packaging-only changes; application sources, Cargo.lock and vendored crates are unchanged.
