ADRs (3)

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

   This feature hub owns normative MUST/SHOULD contract text for Rules pipeline contract.

   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/semantic-pipeline/rules-pipeline-contract/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 Rules pipeline contract.

   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_analysis/src/analysis/rules/
   • compiler/crates/beskid_analysis/src/analysis/diagnostic_kinds.rs
   • compiler/crates/beskid_analysis/src/services.rs

3. 0003-staged-semantic-rules Staged semantic rules pipeline Accepted

   Monolithic semantic passes blocked incremental invalidation.

   Context

   Monolithic semantic passes blocked incremental invalidation.

   Decision

   Semantic rules are grouped in analysis/rules/staged/ with explicit stage boundaries wired through services.rs for CLI and LSP.

   Consequences

   New rules declare their stage; cross-stage dependencies are documented in the hub articles.

   Verification anchors

   • compiler/crates/beskid_analysis/src/analysis/rules/.

  Parent feature hub

This article documents verification and traceability for rules pipeline contract in the reference compiler.

What this covers

For newcomers, this page explains where the contract shows up in day-to-day compiler work and which code paths are most useful first reads.

Anchored code paths

• compiler/crates/beskid_analysis/src/analysis/rules/ defines staged rule groups.
• compiler/crates/beskid_analysis/src/analysis/diagnostic_kinds.rs classifies emitted diagnostics.
• compiler/crates/beskid_analysis/src/services.rs wires semantic services used by CLI/LSP.

Practical notes

• Prefer tracing from CLI/test entry points into analysis/codegen crates before changing internals.
• Treat diagnostics and tests as part of the contract, not optional implementation details.
• If behavior changes, update this article and add/adjust tests in compiler/crates/beskid_tests or compiler/crates/beskid_e2e_tests.
