# Which Problems Are Solved
In the "new" structured logging, request details were added in different
middlewares, such as request, instance and user IDs. This meant the the
upstream request logging middleware did not have access to metadata that
got added later, resulting in incomplete logs. Furthermore it was not
possible to correlate an API error response to log output.
# How the Problems Are Solved
A mutable request details object is added to the context early on. When
the api authz function run, the instance and user IDs are added to this
object as they become available. Every logline emitted after this
(time-wise) will then all contain these details under the `request` log
group.

Request IDs are now also returned with a response header or metadata.
Depending on the protocol:
- HTTP calls always return the request ID as header, regardless of
status
- gRPC calls always return the request ID as header, even if there was
an error
- connect RPC calls returns the request ID as header on success, trailer
in case of error. This is because header must be set on the response
object, which is nil in case of error. When there is an error, metadata
can be added which are then sent as trailers.
# Additional Changes
- Use the existing call duration middleware for both request ID and
logging for a consistent request start timestamp in all layers.
- Upgrade sloggcp for some fixes (notably TraceID)
- Modify the NoCache middleware so it uses `SetHeaders` instead of
`SendHeaders`. The latter prevented any other handler from setting
headers, including the new request ID middleware.

# Which Problems Are Solved
Classic permission checks execute for every returned row on resource
based search APIs. Complete background and problem definition can be
found here: https://github.com/zitadel/zitadel/issues/9188
# How the Problems Are Solved
- PermissionClause function now support dynamic query building, so it
supports multiple cases.
- PermissionClause is applied to all list resources which support org
level permissions.
- Wrap permission logic into wrapper functions so we keep the business
logic clean.
# Additional Changes
- Handle org ID optimization in the query package, so it is reusable for
all resources, instead of extracting the filter in the API.
- Cleanup and test system user conversion in the authz package. (context
middleware)
- Fix: `core_integration_db_up` make recipe was missing the postgres
service.
