# Which Problems Are Solved
- Token exchange rejects `urn:zitadel:iam:org:roles🆔{orgID}` when
that scope is not already present on the subject or actor token
(`invalid_scope`).
- A documented least-privilege pattern — exchanging a broad access token
for one whose roles claims are limited to a single organization — has
been broken since the v4.15.3 token-exchange hardening and was not
restored by #12312.
- A naive allow-any-`roles:id` exception would let a previously narrowed
token widen again (switch org filter, or drop the filter and get all
role orgs), including via an actor token's filter on actor-path
exchanges.
- A client-requested bare `urn:zitadel:iam:org:roles🆔` (empty org id)
is not a meaningful filter and should be rejected on exchange.
# How the Problems Are Solved
- Treats `OrgRoleIDScope` as a restriction filter with downscope-only
semantics via `applyOrgRoleIDScopeDownscoping(requested,
ceilingScopes)`:
- union / standard exchange passes the **subject** token scopes as the
ceiling (actor filters ignored)
- impersonation (scopeless `user_id` / `id_token` subject) passes the
**actor** token scopes as the ceiling
- ceiling unfiltered → any requested `roles:id` is allowed (broad →
narrow)
- ceiling filtered → requested filters must be ⊆ that set
- ceiling filtered but request omits them → inherit the ceiling (omit
must not re-widen)
- Rejects a **client-requested** bare `urn:zitadel:iam:org:roles🆔` in
`validateTokenExchangeScopes` after normalize (before empty-request
fallback). Input tokens may still carry the bare prefix as a degenerate
ceiling; empty-request / omit inherit does not re-trigger the rejection.
- Keeps non-restriction scopes on the existing subject ∪ actor presence
checks.
- Adds unit coverage for downscope, further downscope, widen rejection,
omit-inherit, mixed subject/actor filters, empty-scope access/JWT
subjects, and bare-prefix request/ceiling cases.
- Adds an integration test for broad → `roles:id` filtered roles, plus a
second exchange that rejects widening to another org.
- Documents downscope-only and omit-inherit behavior in the reserved
scopes table and the token exchange guide.
# Additional Changes
- Updates the token-exchange guide Scope section to reflect that
authorization-related reserved scopes must already be present on input
tokens (aligned with the v4.15.3 hardening), rather than suggesting
scope can be freely extended.
# Additional Context
- Closes#12413
- Follow-up for PR #12312
- Related discussion in #11869 (recommended `roles:id` workaround; this
restores that path for token exchange without allowing filter widening)
- Behavior note for release notes: during token exchange, an existing
`urn:zitadel:iam:org:roles🆔*` filter on the subject is inherited when
omitted from the request, so role claims cannot re-widen.

# Which Problems Are Solved
As part of the naming consistency initiative, the terms Authorization,
User grants, internal authorization and other similar terms that are
used in the context of assigning project roles to users are replaced by
Role Assignments in the UI, API docs, and documentation.
# How the Problems Are Solved
By replacing the following terms with Role Assignments in API docs,
Console UI, and guides.
- Authorization
- internal authorization
- external authorization
- User Grant
- Roles and Authorizations
By adding a note in the API docs to make it clear that Authorization
within the context of Authorization Service API refers to role
assignments, not to OAuth authorization as it is still used in the APIs.
By updating some screenshots in documentation / guides to show "Role
Assignments" instead of "Authorizations" in the UI.

In many cases IAM was used where instance was meant.

architecture.

## Todos for release
- [x] Configure Env in docs project on vercel
- [x] Configure Root Path in the docs project on vercel
- [ ] Remove old CSP https://github.com/zitadel/website/pull/1592
## What we did
This pull request migrates the project documentation from the old
`docs/` directory to the new `apps/docs/` directory, introduces a new
documentation system built with Next.js and Fumadocs, and updates all
relevant references, configuration files, and documentation to reflect
this change. It also adds new configuration and ignore files for the new
documentation app, updates CI and linting to exclude the new docs from
certain checks, and revises the contributing guidelines accordingly.
**Documentation System Migration and New Docs App**
* Migrated all documentation from `docs/` to `apps/docs/`, and updated
all references in `README.md`, `CONTRIBUTING.md`, and other files to
point to the new location.

* Added a new Next.js/Fumadocs-based documentation app under
`apps/docs/`, including core app files, layouts, routing, search API,
and a comprehensive `README.md` with development and contribution
instructions.

**Configuration and Tooling Updates**
* Updated `.github/workflows/codeql.yml`, `.golangci.yaml`, and
`.github/dependabot.yml` to properly handle the new docs app: excluded
`apps/docs` from certain checks, added npm dependency updates for the
docs app, and excluded generated content.

* Updated `.devcontainer/devcontainer.json` to use the latest Go 1.25.3
version for consistency.
**Licensing and Miscellaneous**
* Added `apps/docs/` to the list of licensed directories in
`LICENSING.md`.
These changes ensure the documentation is now maintained in a modern,
scalable system and all project tooling is updated to support the new
structure.
