ADRs (3)

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

   This feature hub owns normative MUST/SHOULD contract text for Diagnostic code registry.

   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/diagnostic-code-registry/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 Diagnostic code registry.

   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/diagnostic_kinds.rs
   • compiler/crates/beskid_analysis/src/analysis
   • compiler/crates/beskid_analysis/src/doc/validate.rs

3. 0003-codes-owned-in-analysis Diagnostic codes owned in analysis sources Accepted

   Rendered diagnostics drifted from semantic registry.

   Context

   Rendered diagnostics drifted from semantic registry.

   Decision

   Code-to-meaning mapping is normative in SemanticIssueKind::code() and diagnostic_kinds.rs, synchronized with trudoc verify scripts—not LSP presentation layers.

   Consequences

   Renaming codes requires migration notes; new issues need unique codes before release.

   Verification anchors

   • compiler/crates/beskid_analysis/src/analysis/diagnostic_kinds.rs
   • packages/trudoc/scripts/verify-diagnostics-spec-sync.mjs.

  Diagnostics parity

  Registry consistency drives parity across build surfaces

Code lifecycle algorithm:

1. Define or reuse an issue kind in diagnostic_kinds.rs.
2. Emit that kind from a semantic rule in analysis/rules.
3. Convert issue kind to stable code/category payload.
4. Surface payload through services to CLI and LSP.
5. Validate docs and source sync with diagnostics verification scripts.

The code identity must survive every handoff unchanged, even when message templates differ between clients.
