OpenMausBot redistributes two executables from the official Cua Driver ${RELEASE_VERSION} Linux x64 release: \`cua-driver\` and \`cua-cursor-theme\`.

- Upstream source commit: [\`${SOURCE_COMMIT}\`](https://github.com/trycua/cua/commit/${SOURCE_COMMIT})
- Upstream \`Cargo.lock\` SHA-256: \`${CARGO_LOCK_SHA256}\`
- Release archive SHA-256: \`${ARCHIVE_SHA256}\`
- Cua's ${TRYCUA_COUNT_WORD} workspace components remain under the accompanying MIT \`LICENSE.md\`.
- The embedded Inter ${INTER_VERSION} font remains under the accompanying SIL OFL 1.1 \`Inter-OFL-1.1.txt\`.
- Full license texts and attribution for all ${EXPECTED_REGISTRY_UNION_COUNT} crates.io packages and Inter are in \`THIRD_PARTY_LICENSES.html\`.
- The machine-readable inventory contains ${EXPECTED_REGISTRY_UNION_COUNT} registry packages, ${TRYCUA_COMPONENTS.length} Cua packages, and Inter in \`SBOM.cdx.json\`.

## MPL-2.0 source availability

The shipped build graph contains exactly the following MPL-2.0 components. Their corresponding Source Code Form is available from the versioned crates below:

${mplSourceRows.join("\n")}

The complete MPL-2.0 text and package copyright notices appear in \`THIRD_PARTY_LICENSES.html\`. These files remain under their original licenses; OpenMausBot's and Cua's MIT licenses do not replace them.

## Scope and method

The registry inventory is the union of two root-scoped \`cargo-about 0.8.4\` graphs: \`cua-driver\` with \`portal-input\` for \`x86_64-unknown-linux-gnu\`, and \`cursor-theme-cli\` for the same target. Development-only dependencies are excluded; build dependencies are retained. Raw workspace-unified Cargo metadata is not used as the inventory because features enabled only by unrelated workspace members would overstate the shipped graph.
