The documentation check of the backend found the private members of
ViGet/ without a summary and no page for its namespace:
- Summaries for every field and helper method of the catalog, the
  descriptor, the properties reader, publishing and the endpoints.
- docs/api/namespaces/Progmasoft.Progmaweb.Api.ViGet.md describes the
  namespace.
- The two regular expressions of TazelPluginDescriptor are excluded from the
  reference like AccountNamePolicy.CanonicalPattern: the generator replaces
  their comment with its own.

The dependency audit found GHSA for zod < 4.6.6, which can exhaust memory
while validating oversized constrained collections. Only
eslint-plugin-react-hooks reaches it, and it accepts any zod 4, so an
override takes 4.6.7 until the plugin resolves a fixed release itself.
pnpm audit --audit-level high finds nothing.

Progmasoft OAuth now runs on three hosts:

- credentials.progmasoft.com stays the issuer: discovery documents, key
  set, token, user information, revocation and introspection.
- authorize.progmasoft.com serves the pages people see: the
  authorization and end session endpoints (registered with OpenIddict as
  absolute URIs on that host), sign-in, the consent screen and the
  applications an account has allowed.
- console.progmasoft.com is the Progmasoft Console. Its overview links
  the areas; OAuth 2.1 tokens live under /credentials, with New token,
  then the application type, then its form.

The console has no sign-in of its own and never redirects. It uses the
Progmasoft account session, so production now shares that cookie with
progmasoft.com (__Secure-ProgmasoftSession, Domain=progmasoft.com,
HttpOnly, Secure, SameSite=Lax). Without AccountSessions:CookieDomain the
cookie stays host-only with the __Host- name, as in development and tests.

Application types replace the confidential/public switch: web,
single-page, desktop, mobile and service. Each type has its redirection
rules (RFC 8252), its secret or none, and its grants; only a service
uses client credentials and it registers no address or scope. The type is
kept as an application property and cannot change.

The HTML pages of the API are gone. The pages are Next.js pages in four
languages (en-US, de-DE, ru-RU, he-IL) that call JSON endpoints under
/api/v1/oauth. Requests that change state must come from the page's own
origin; antiforgery forms are no longer needed. The token, revocation and
user information endpoints answer CORS requests from the origins of
single-page applications, without credentials; the discovery documents
and the key set answer every origin.

The host filter keeps every path on its host. Nginx gains the authorize
and console virtual hosts, and the docs describe the hosts, the types and
the shared session.

The documentation check of CI requires a comment on every API item and
a page for every namespace; 38 items of Progmasoft.OAuth had none. The
private handlers and helpers get summaries, MemoryOAuthDatabase its
field, and docs/api/namespaces describes Progmasoft.OAuth and its
Developers, Endpoints, Pages and Storage namespaces.

Verified: dotnet build in Release, dotnet docfx with warnings as
errors, and CheckDocumentation: all 353 API items are documented.

The DocFX gate only failed on a broken link or an unresolved reference.
DocFX does not report a declaration without a comment, and the API had
none, so the gate passed over a reference with no descriptions at all.

The gate now has three parts:

- DocFX still builds the reference with warnings as errors.
- The API project compiles its XML documentation. With warnings as errors
  already on, an undocumented public declaration or a wrong cref now fails
  the build.
- docs/api/CheckDocumentation.cs reads the metadata DocFX generated and
  fails when a namespace, type or member has no summary. This covers
  internal and private members, which the compiler does not check. It runs
  as a file-based .NET program, so the gate needs no tool beyond the SDK.
  It refuses to pass when the metadata is missing or defines nothing.

To satisfy the gate, every declaration of apps/api has documentation
comments, 131 reference items in all, and the two namespaces are described
by overwrite files in docs/api/namespaces. Only comment lines were added to
the C# sources; no statement changed.

docs/api/filterConfig.yml leaves generator-written code out of the
reference: the generated regular-expression namespace, and the one partial
method whose generated half replaces the comment of its declaration.

Verified locally: the solution builds with no warnings, the 23 API tests
pass, DocFX builds with no warnings and the coverage check passes. Removing
one summary and one namespace file made the check fail and name both.
