feat(guardrails): Add intermediate information fields to guardrails execution in the callback payload - #1195
feat(guardrails): Add intermediate information fields to guardrails execution in the callback payload#1195Prajna1999 wants to merge 16 commits into
Conversation
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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- 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.

update the preservation assertion in the Sentry filter tests to reflect that
callback_url is redacted before export.

- Line 228: Update update_llm_call_response so LlmCall.metadata_ receives a
newly constructed dictionary after merging existing metadata with the response
metadata, rather than mutating and reassigning the same dict; preserve existing
values while ensuring the JSONB change is detected before commit.

this forwards the upstream response verbatim (any JSON shape, including error bodies), and we don't validate it here, so there's no concrete schema to type.

Same as above — this body is proxied straight through to the guardrails service verbatim, which owns the schema. This avoids enforcing schema twice

These routes intentionally pass through the upstream status code and body unchanged, including 4xx/5xx. APIResponse would force a 200 and rewrap the payload, breaking that.

I think instead of making this as function, create the one array constant and then directly check from that constant variable.

not need to put the log here, it's already return in the response. at least try to minimize the use of loggers, because Claude tends to start adding a logger to every function. We should only add them where they’re actually needed, since they’re mostly not required.
Trims overlong code comments, drops redundant log lines in the guardrails proxy, and extracts auth error status codes into a constant, per PR #1195 review feedback. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…toggle Guardrail input/output text and per-validator results were always attached to llm_call metadata whenever guardrails ran, leaking pre-sanitisation text by default. Add include_guardrail_metadata on LLMCallRequest (default false) to make this opt-in. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Issue
Closes #1187
Summary
Fixed output guardrails not being applied to the LLM's actual response — the response was being validated/persisted before the output-guardrail mutation ran, so GET /llm/call/{job_id} served stale, unredacted text.
Added a generic metadata_ column on LlmCall so guardrail results are visible on both the callback path and the polling endpoint, not just the callback.
Restructured the metadata payload into a readable input_guardrail/output_guardrail shape (user_input, input_sent_to_llm, llm_output_pre_guardrail, response_to_user, per-validator validators[]) instead of embedding the raw nested guardrails-service response.
Added a Sentry before_send filter to strip end-user query/response text from the celery-job context that CeleryIntegration auto-attaches to events for the LLM/chain/response job tasks.
Added unit and integration-level tests for the new metadata shape, the content-persistence fix, and the Sentry redaction.
New response body sent to the caller
