ADRs (3)

1. 0001-feature-hub-authority Feature hub authority Accepted

   This feature hub owns normative MUST/SHOULD contract text for Test harnesses and fixtures.

   Context

   Sibling articles under this feature previously restated requirements in inconsistent forms.

   Decision

   This feature hub owns normative MUST/SHOULD contract text. Sibling articles must not redefine hub requirements and should link here for authority.

   Consequences

   Contract changes start on the hub or in linked ADRs, then propagate to articles and implementation anchors.

   Verification anchors

   • site/website/src/content/docs/platform-spec/compiler/conformance/test-harnesses-and-fixtures/index.mdx
   • article bundle under the same feature directory.

2. 0002-spec-over-implementation-notes Specification over implementation notes Accepted

   Platform-spec text supersedes informal crate comments for Test harnesses and fixtures.

   Context

   Implementation crates accumulated informal notes that diverged from published contracts.

   Decision

   Normative platform-spec prose and ADRs under this feature supersede informal comments in implementation crates until explicitly migrated into spec text.

   Consequences

   Engineers file spec/ADR updates when behavior changes; crate comments are non-authoritative for conformance arguments.

   Verification anchors

   • compiler/crates/beskid_tests/src/analysis
   • compiler/crates/beskid_tests/src/runtime
   • compiler/crates/beskid_e2e_tests/src/tests/runtime_cases.rs

3. 0003-primary-contract-choice Primary contract for Test harnesses and fixtures Accepted

   This feature explains how the project proves that implemented behavior remains stable release over release. It is organi

   Context

   This feature explains how the project proves that implemented behavior remains stable release over release. It is organized into newcomer-friendly articles that move from model, to flow, to contracts, then practical verification and debugging guidance.

   Decision

   The reference compiler must implement Test harnesses and fixtures as documented in this feature hub and its article bundle.

   Consequences

   Changes require hub/ADR updates and verification anchor extensions.

   Verification anchors

   • compiler/crates/beskid_tests/src/analysis
   • compiler/crates/beskid_tests/src/runtime
   • compiler/crates/beskid_e2e_tests/src/tests/runtime_cases.rs

Verification strategy

• Unit-level checks validate local transformations.
• Integration tests validate crate-to-crate contracts.
• End-to-end fixtures validate user-visible behavior.

Traceability map

• Spec requirement source: /platform-spec/compiler/conformance/test-harnesses-and-fixtures/.
• Core implementation anchors:
  • compiler/crates/beskid_tests/src/analysis fixture-driven semantic assertions
  • compiler/crates/beskid_tests/src/runtime runtime behavior checks
  • compiler/crates/beskid_e2e_tests/src/tests/runtime_cases.rs source-to-runtime outcomes
• Conformance anchor:
  • compiler/crates/beskid_tests/src/doc_tests.rs docs-driven verification

Review checklist

• Requirement text and test expectation describe the same boundary.
• Crate ownership updates are reflected in spec links.
• Newly introduced edge cases include at least one reproducible fixture.
