ADRs (3)

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

   This feature hub owns normative MUST/SHOULD contract text for Crate-to-spec anchors.

   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/implementation-map/crate-to-spec-anchors/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 Crate-to-spec anchors.

   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/

3. 0003-crate-map-single-index Crate-to-spec anchor map is canonical index Accepted

   Canonical index from compiler crates to platform-spec features.

   Context

   Crate references were scattered across hubs without a single ownership surface.

   Decision

   This feature hub is the canonical map from compiler/crates/* to platform-spec features; other pages link here instead of duplicating tables.

   Consequences

   New crates require anchor rows before Standard promotion of dependent features.

   Verification anchors

   • Implementation-map articles and compiler/Cargo.toml workspace layout.

End-to-end flow

1. Input enters compiler/runtime boundary at a stable entrypoint.
2. The responsible crate enforces the expected shape and emits stable structures.
3. Downstream crates consume those structures without redefining semantics.
4. Conformance tests assert behavior at integration boundaries.

Algorithm notes for newcomers

• Prefer tracing one fixture end-to-end before reading all modules.
• Verify where shape conversion happens; avoid assuming all crates mutate data.
• Keep an eye on handoff points where diagnostics or ABI constraints are locked.

Where to step through code

• Start with “beskid_analysis -> parser/resolution/semantic leaves.
• Then inspect “beskid_codegen -> lowering contract leaves.
• Follow consumption path at “beskid_abiandbeskid_runtime -> execution ABI/runtime leaves.
• Validate expectations using “beskid_testsandbeskid_e2e_tests -> conformance leaves.
