Review Change Stack

Walkthrough

The change adds shield configurations and E2E coverage for shield catalogs, question validation, redaction, and shield_ids overrides. It adds a dedicated shields test shard and disables automatic triggers for the Lightspeed evaluation workflow.

Changes

Shield E2E coverage

Layer / File(s) Summary
Shield configurations
examples/lightspeed-stack-shields.yaml, tests/e2e/configuration/*/lightspeed-stack-shields*.yaml
Adds configured, empty, and override-disabled shield fixtures for library and server modes.
Shield catalog validation
tests/e2e/features/shields.feature, tests/e2e/features/info.feature, tests/e2e/features/steps/info.py, tests/e2e/test_list.txt
Adds exact checks for configured and empty GET /v1/shields responses, removes the older check, and registers the new features.
Shield request behavior
tests/e2e/features/shields_question_validity.feature, tests/e2e/features/shields_redaction.feature, tests/e2e/features/shields_overrides.feature
Tests question validation, numeric redaction, streaming responses, shield selection, and invalid override responses.
Shield test routing
Makefile, .github/workflows/e2e_tests.yaml
Adds @cfg_shields to the default E2E expression and creates a dedicated shields shard.

Evaluation workflow trigger

Layer / File(s) Summary
Disable automatic evaluation runs
.github/workflows/e2e_tests_lightspeed_evaluation.yaml
Replaces push and pull request triggers with an empty trigger configuration.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 69ab0

The PR adds shield end-to-end scenarios that currently cannot exercise the configured moderation, redaction, or override behavior, and it changes a workflow to an invalid empty trigger that cannot pass syntax checks. The PR is not merge-ready until these test execution paths and the workflow trigger are corrected.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (15 skipped: 15 unsupported.)

Full details: Performance And Algorithmic Complexity

Explanation

PASSED. The pull request changes only E2E workflows, Makefile tag selection, example/test YAML, and finite Gherkin scenarios. No production source, handler, database, Kubernetes list operation, cache, watcher, or API pagination logic changed. The added @cfg_shields shard and shield scenarios increase CI/test work, but they do not introduce any failure condition listed by this check.

Full details: Security And Secret Handling

Explanation

PASSED. The changed files introduce no real secrets or plaintext secret logging. The only added api_key values are the established dummy xyzzy test placeholder, also used throughout existing E2E fixtures and documented as the default test key. The /v1/shields endpoint is unchanged from main and requires both Depends(get_auth_dependency()) and @authorize(Action.GET_SHIELDS); the new auth_enabled: false and noop settings are test-only fixtures. The endpoint returns shield metadata only and logs a shield count, not request data or credentials. No changed file adds a Kubernetes Secret resource, SQL/command/path traversal sink, or other sensitive response path.

In @.github/workflows/e2e_tests_lightspeed_evaluation.yaml:
- Line 4: Update the workflow trigger configuration so the on section is not an
empty array; use the workflow_dispatch trigger to support manual runs, or remove
the empty trigger while disabling the workflow through GitHub if it must remain
inactive.

In `@tests/e2e/features/shields_question_validity.feature`:
- Around line 24-27: Implement shield execution in run_shield_moderation instead
of always returning ShieldModerationPassed(): apply question_validity before
inference and return invalid_question_response for rejected input; execute
configured redaction rules before returning responses; and honor the selected
shield_ids list when running moderation. Affected sites:
tests/e2e/features/shields_question_validity.feature lines 24-27 require
question-validity enforcement; tests/e2e/features/shields_redaction.feature
lines 27-50 require configured redaction execution;
tests/e2e/features/shields_overrides.feature lines 23-26 require applying
selected shield IDs.
