raven-web.dll serves HttpClient, HttpBaseProtocolFilter with its cache
control, HttpMethod, HttpRequestMessage, HttpResponseMessage, the request,
response and content header collections (with Connection, User-Agent,
dates, lengths and Retry-After typed), response content read as a
buffer, string or stream, and Windows.Foundation.Uri over urlmon's IUri.
Requests go through WinINet, which Windows' base protocol filter sits on
too; redirections are followed and reflected in the request's URI.
winget checks its package source's version with a HEAD request this way.
The interfaces are the C declarations generated from Microsoft's
published metadata (windows.web.http.h, on raven-winrt's foundation.h);
the component is always built. native/upstream/raven-winrt holds the
plumbing the classes share (objects answering several interfaces,
asynchronous operations, boxed values, buffers, string maps, item
lists), for later components to use as well. Typed header values not
modelled yet, the request property bag, transport information and
custom certificate validation answer E_NOTIMPL.

AI-Scope: the component, the shared plumbing, CMake and registry wiring, the web_client test
raven-appx.dll serves the AppxFactory and AppxBundleFactory classes
that package managers open packages with (winget reads its source
package this way). A package reader checks that the package is a ZIP
archive (ZIP64 records included) with a manifest, a block map and
content types, and that the block map lists every payload file with its
size; a file's content is then inflated and checked against the block
map's hash one 64 KiB block at a time as it is read, failing with
APPX_E_CORRUPT_CONTENT where it differs. The manifest reader gives the
identity with the package's full and family names, properties,
dependencies, target device families, capabilities, resources,
prerequisites and applications; the block map reader its files and
blocks. A bundle opened as a package, or a package as a bundle, answers
APPX_E_MISSING_REQUIRED_FILE, as programs tell the two apart.
The component is built by provision-installer.py beside cabinet.dll, on
the same zlib, and reads XML with xmllite; the factories are registered
in both registry views. Writing packages, reading bundles, block maps
validated against a signature, IAppxDigestProvider and the later
manifest reader interfaces answer E_NOTIMPL.
The test writes its packages with appx_fixtures.py, as package writers
make them, and reads them back in 64-bit and 32-bit processes.

AI-Scope: Added missing window, GDI, memory, text and multibyte behavior in the host that the own guest components need.
Programs ask Windows.System.Profile.AnalyticsInfo which device family and
version of Windows they run on; winget's engine activates it by name. The
class joins RetailInfo and SharedModeSettings in raven-twinapi.dll: the
family is Windows.Desktop, its version the four numbers RtlGetVersion and
the registry's update build revision give, packed in sixteen bits each and
written in decimal, and the form Desktop.
