ADRs (3)

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

   This feature hub owns normative MUST/SHOULD contract text for Resolver 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/resolver-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 Resolver 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/resolve/resolver.rs
   • compiler/crates/beskid_analysis/src/resolve/items.rs
   • compiler/crates/beskid_tests/src/analysis/resolve.rs

3. 0003-primary-contract-choice Primary contract for Resolver contract Accepted

   This feature hub defines the normative contract for **resolver contract** and links newcomer-oriented reference articles

   Context

   This feature hub defines the normative contract for resolver contract and links newcomer-oriented reference articles.

   Decision

   The reference compiler must implement Resolver contract 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_analysis/src/resolve/resolver.rs
   • compiler/crates/beskid_analysis/src/resolve/items.rs
   • compiler/crates/beskid_tests/src/analysis/resolve.rs

  Parent feature hub

This article documents flow and algorithm for resolver 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/resolve/resolver.rs owns name resolution and scope lookup.
• compiler/crates/beskid_analysis/src/resolve/items.rs resolves item-level references.
• compiler/crates/beskid_tests/src/analysis/resolve.rs exercises resolver behavior in tests.

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.
