# SumWise 2.6.0 — third-party source and build information

Qt version: 6.10.1, Windows x64 shared libraries/plugins. These materials are
third-party sources and notices, not the proprietary SumWise application.
Source availability does not announce public availability of SumWise 2.6.

## Included materials and verification

INVENTORY.json lists the delivered files and SHA-256 hashes. Download files
with their relative folder names intact. SHA256SUMS.txt also supplies checksums.
The complete QtBase/QtSvg vendor archives, exact public-suffix source, selected
patch/generator files and authentic notices are unchanged from the verified
source companion. LIBRARY-MAP.json identifies the corresponding runtime DLLs.
The inventory itself and the checksum list do not recursively hash themselves.
The web index lists download sizes and hashes, including those two files.

Supplier configuration files retain historical supplier build-machine paths.
They are provenance, not paths you must possess or commands to execute blindly.
No private SumWise repository or signing key is required to rebuild Qt.
Microsoft release CRTs and SDK graphics components retain their supplied terms;
the Qt source archives do not purport to supply Microsoft proprietary source.
Windows ICU/Schannel are OS-provided; no Mesa or OpenSSL implementation is shipped.

## Build a compatible QtSvg

Use an x64 MSVC developer environment, CMake, Ninja, and matching Qt 6.10.1
release development files (including private headers and BuildInternals).
This demonstration used MSVC 19.51.36257 / tools 14.51.36231, against the matching
Qt 6.10.1 msvc2022_64 SDK. Qt's supplied build metadata reports MSVC 19.39.33520.
This is compatible-module engineering evidence, not bit-for-bit vendor rebuild.

Extract `archives/qtsvg-everywhere-src-6.10.1.tar.xz` into a fresh source
folder; keep the archive untouched. Set QT_PREFIX to the matching development
installation and WORK to an isolated build parent. From that environment:

```text
cmake -S <extracted-qtsvg> -B <WORK>/qtsvg-build -G Ninja
  -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=<QT_PREFIX>
  -DCMAKE_INSTALL_PREFIX=<WORK>/qtsvg-prefix
  -DCMAKE_C_COMPILER=cl.exe -DCMAKE_CXX_COMPILER=cl.exe
  -DQT_BUILD_TESTS=OFF -DQT_BUILD_EXAMPLES=OFF -DQT_BUILD_DOCS=OFF
  -DQT_GENERATE_SBOM=OFF
cmake --build <WORK>/qtsvg-build --target Svg --parallel 2
```

Treat the configure block as one command with local path substitutions. This
build produces `qtsvg-build/bin/Qt6Svg.dll`; no install step is required and the
installed Qt tree must not be replaced. Tests/examples/docs/SBOM are omitted
from this small probe build, not from the supplied corresponding source.

## QtBase and compatibility

For QtBase, the complete source and supplier feature summary/options are present.
A recipient rebuilding QtBase should use its own clean prefix and compatible
MSVC x64 toolchain, preserve matching enabled interfaces/plugins, then rebuild
dependent modules against that prefix. The supplier options identify dynamic
OpenGL, shared release/debug libraries and bundled zlib among the configuration;
consult the included summary for each feature. Supplier cache/SBOM tool paths
must be replaced with locally available equivalents or non-runtime build
reporting options, not blindly executed. The OpenSSL plugin is only a backend;
no OpenSSL implementation is distributed. Schannel is the selected available
TLS implementation. Full QtBase reconstruction and arbitrary future ABI changes
were not tested here. Do not mix mutually incompatible Qt builds.


## Run with the Store-associated application

Use RECIPIENT-INSTRUCTIONS.txt for obtaining your own installed application
payload, Windows development-registration prerequisites, data-loss warnings,
identity/path guards, testing and Store restoration. Do not apply the Direct
edition's licensing rules to a Store copy. This is a technical mechanism with
stated test limits, not legal certification or final Store-update acceptance.

Licence texts are in notices/Qt and notices/. The exact preferred public-suffix
source is sources/public_suffix_list.dat at commit
2141aa8a1f634c2b839175c559ceaac6a849592c. Source availability continues under the
applicable licences. For a broken download, use the existing SumWise support
contact at https://sumwisecalc.com/support and name this 2.6.0 source companion.
