Exercise the enterprise-contract ITS pipeline definition end-to-end using a built and signed image. Cover successful validation, strict policy rejection, and non-strict failure reporting. Check overall PipelineRun status, the verification task's result, and the pipeline's exported TEST_OUTPUT for successful runs.

The Tekton runner includes the ITS suite by default and accepts separate ITS repository, revision, and path parameters, exporting them as ITS_PIPELINE_* settings. A label-filter parameter lets pipeline PRs select only the ITS suite. Correct the new suite's timeout to use the seconds expected by the pipeline helpers. Document how the E2E test revision differs from the pipeline source revision.

Validation: compilation and Ginkgo dry runs passed for the ITS-only filter and the combined suite. All three ITS scenarios are selected. Tekton schema validation and parameter wiring checks passed for the runner and companion CLI trigger. Live cluster E2E validation remains pending because the configured cluster hostname does not resolve.

Related: EC-1943. Companion CLI trigger: conforma/cli#3574 (draft, depends on this PR).

This PR supplies the test suite and runner support. Keep EC-1943 open until the CLI trigger is validated with both a passing run and an intentionally broken bundle reference, and merge-rule integration is completed.

📝 Walkthrough

Walkthrough

Adds ITS Pipeline E2E tests for policy evaluation, Git-based PipelineRun generation, and configurable pipeline source settings. The E2E commands and Tekton pipeline now select both ec and its-pipeline tests by default.

Changes

ITS Pipeline E2E

Layer / File(s) Summary
ITS Pipeline configuration and generation
pkg/constants/constants.go, pkg/utils/tekton/generators.go
Adds repository defaults and environment-variable names. Adds Git resolver references and ITSPipeline.Generate to create PipelineRuns with snapshot and policy parameters.
ITS Pipeline E2E scenarios
tests/its_pipeline/its_pipeline.go
Adds suite setup for image signing, Chains verification, and policy configuration. Tests successful policy evaluation, strict-mode failure, and non-strict reporting.
E2E pipeline wiring and instructions
.tekton/pipelines/conforma-e2e/pipeline.yaml, cmd/e2e_test.go, Makefile, README.md
Passes ITS Pipeline source and label-filter settings to the test process. Registers and selects the ITS Pipeline tests. Documents source parameters and defaults.

Merge Risk: ⚪ Minimal · up to 4bbba

The source wiring matches the documented defaults, and the new scenarios assert their stated outcomes. Live-cluster validation remains pending, but no concrete merge-blocking behavior is established by the available evidence.

Seems to need a rebase. Some of the bot suggestions seems reasonable, did you consider addressing them?

Exercise the enterprise-contract ITS pipeline definition from
conforma/cli end-to-end so that regressions and breakages are
caught pre-merge. The pipeline location is configurable via
ITS_PIPELINE_REPO_URL, ITS_PIPELINE_REVISION, and ITS_PIPELINE_PATH
env vars, enabling conforma/cli CI to test PR branches.

Three test cases:
- Pipeline succeeds when policy is met
- Pipeline fails in strict mode when policy is not met
- Pipeline reports failure but does not fail in non-strict mode

Update Makefile label filter from "ec" to "ec || its-pipeline"
so CI runs both the existing EC task tests and the new ITS
pipeline tests.
