lgtm, I'd just add those additional queries for some flexibility

Please add a aggregated query for groups of jobs by the status - "succeeded", "failed", "killed", "skipped" - status, count
Use case is: how many jobs failed for last month?

The query default is to get data for last 7 days. Do you care about the last month? Or you want to maybe have even two different queries?

7 days is fine, let's start with this and see if there are any requirements from people consuming this

would it make sense to add a simple generic aggregate query by one column?
use cases:
- count of jobs grouped by a source app
- count of jobs grouped by a tenant
the output would always be two columns, one is the key, the other is the count

I like the idea. But this is, from my point of view, adding extra logic, that should be implemented in one of the following tasks. From ManCo I got one query, that they ask for (current get_runs_jobs_detail) - I love to add the groups of jobs by the status query as additional useful one. However would move others as a part of another task. What do you think?

In `@api.yaml`:
- Around line 331-468: Update the named-query route and
HandlerNamedQuery.handle_request flow to require JWT authentication and enforce
the authenticated user’s authorization for the requested topic before executing
the query. Remove the operation-level security override of security: [] and
reuse the existing authentication and per-topic authorization mechanisms used by
comparable stats routes, returning the established unauthorized response when
access is denied.
In `@src/handlers/handler_named_query.py`:
- Around line 71-76: Update the validation rejection paths in the handler method
containing _validate_event_path_params and _validate_event_body so every
returned non-2xx validation response emits one warning log with the rejection
cause. Either log separately before each return or centralize the warning
immediately before returning the validation response, while preserving the
existing response behavior.
- Line 87: Update the named-query logging calls in handler_named_query.py and
reader_postgres.py to use constant message strings, passing query_name,
topic_name, and row_count through the specified extra mappings instead of
interpolating variables into messages.
- Around line 147-148: Update the limit validation in the named-query handler to
import and enforce POSTGRES_MAX_LIMIT, rejecting values below 1 or above the
maximum with a 400 validation response. Preserve the existing integer and
boolean checks, and update the error message to describe the inclusive
1-to-POSTGRES_MAX_LIMIT range.

Log each validation rejection with its cause.
The repository logging contract requires one explanatory log line for every non-2xx response. The validation helpers return 400/404 responses without a warning. Add one warning at each rejection path or centralize one warning before returning the validation response.

Use constant messages for named-query logs.
The repository logging guideline requires constant messages with variable values in extra. Update both calls:
handler_named_query.py: useextra={"query_name": query_name, "topic_name": topic_name}.reader_postgres.py: useextra={"query_name": query_name, "row_count": len(rows)}.

Reject limits above POSTGRES_MAX_LIMIT.
The OpenAPI schema declares a maximum of 1000. The handler accepts 1001, and ReaderPostgres.read_named_query clamps it to 1000. A successful request therefore returns 200 with a different limit instead of returning 400. Import POSTGRES_MAX_LIMIT in the handler.

Overview
Adds a new
/stats/{topic_name}/query/{query_name}endpoint that executes predefined, registry-driven named queries against PostgreSQL (starting withruns_jobs_detail, reproducing the existing Qlik runs/jobs dashboard feed) with keyset pagination, alongside supporting unit/integration tests, shared response-building utilities, and several pylint/typing cleanups (duplicate-code removal, tighterPaginationtyping, unused-import and config fixes).Release Notes
