Expose the internal kaapi-guardrails management API (validator catalogue, ban lists, LLM prompt configs, validator configs) through 16 passthrough routes behind project auth. Tenant travels only in X-ORGANIZATION-ID / X-PROJECT-ID headers set from the auth context; 401/403/422 from the service fail the job instead of bypassing, with client-visible errors sanitized to status codes only.

Inline comments:
In `@backend/app/api/routes/guardrails.py`:
- Line 101: Update _upstream_response so both the Response and JSONResponse
return branches include the Cache-Control header set to no-store. Apply this
explicitly to each tenant-specific proxy response and do not use private as a
substitute.
In `@backend/app/celery/tasks/job_execution.py`:
- Around line 76-78: Update _run_with_otel_parent to preserve the active Celery
task span while applying the extracted parent context, ensuring spans created by
fn remain children of the task span. Capture the external parent context before
Celery creates its task span or supply it during task-span creation, and add
regression coverage for valid task-span and valid-header scenarios.
- Line 65: Update _run_with_otel_parent by annotating task_instance as Task and
the callback as Callable[[], T], using a TypeVar T so the function return type
preserves the callback’s result type.
In `@backend/app/core/telemetry.py`:
- Line 203: Update the propagator configuration around set_global_textmap and
SentryPropagator to use a composite propagator that injects and extracts both
Sentry and W3C formats, preserving parent context at HTTP and Celery boundaries.

Sensitive Data Exposure (CWE-525): Use of Web Browser Cache Containing Sensitive Information
Reachability: External · Exploitability: Moderate
Prevent cache reuse of tenant-specific proxy responses.
_upstream_response returns a new Response or JSONResponse, and the application middleware does not add cache directives. Add Cache-Control: no-store to both branches. Do not rely on private for tenant isolation.

Add narrow type hints to _run_with_otel_parent.
backend/pyproject.toml enables strict mypy checks, and this untyped helper violates the repository’s typing contract. Annotate task_instance as Task and use Callable[[], T] with a TypeVar for the callback and return value.

- Add test coverage for the 16 new guardrails proxy routes (forwarding, filters, UUID normalization, pagination bounds, route ordering, auth). - Set Cache-Control: no-store on guardrails proxy responses to prevent caching of tenant-scoped data (CWE-525). - Add narrow type hints to _run_with_otel_parent/_extract_parent_context per repo's strict mypy contract.

remove these longs comments and also add testacse for this thing where if guardrails strip a prompt down to nothing, we now stop and fail the job with a clear "guardrails removed everything" message instead of forwarding an empty prompt to the provider and getting back a confusing provider-side error.

Issue
Closes #1151
Summary
For the guardrails service being proxied through kaapi-backend to work, we need to add identical routes to kaapi-guardrails in kaapi-backend too. They must mirror the API request schema parsed without error by kaapi-guardrails service. The routes have been added in this PR.
Also, kaapi-backend sends
X-ORGANIZATION-IDandX-PROJECT-IDpost resolving the X-API-KEY token through the payload for kaapi-guardrails to process i.e REST request verbs are independent of the above two arguments and only concerned with payloads being proxied.X-ORGANIZATION-IDandX-PROJECT-IDover the wire to guardrails service.Checklist
