BE-585, BE-591: HashQL: Add MIR interpreter test suite and refactor diagnostic categories by indietyp · Pull Request #8837 · hashintel/hash

indietyp · 2026-06-08T11:41:44Z

🌟 What is the purpose of this PR?

This PR wires up the MIR interpreter so it can be exercised end-to-end through the compiletest suite, and restructures the diagnostic category hierarchy so that interpreter errors and bridge (PostgreSQL suspension) errors are unified under a single OrchestratorDiagnosticCategory type rather than being conflated under InterpretDiagnosticCategory.

Previously, bridge errors (query execution failures, row decoding, parameter encoding, etc.) were emitted as InterpretDiagnostic values with a Suspension subcategory bolted onto InterpretDiagnosticCategory. This made it impossible for downstream consumers to distinguish interpreter ICEs from orchestrator bridge failures. The new OrchestratorDiagnosticCategory enum has two variants — Interpret (forwarding interpreter errors) and Bridge (wrapping suspension failures) — giving callers a coherent, single diagnostic type from the orchestration layer.

On the interpreter side, RuntimeError::into_diagnostic is split into into_diagnostic (same category, InterpretDiagnosticCategory) and into_diagnostic_with (maps the category through a caller-supplied closure), enabling the orchestrator to embed interpreter diagnostics inside its own hierarchy without losing information.

A new mir/interpret compiletest suite is added that runs the full pipeline through the MIR interpreter and captures the output, with an initial test demonstrating that field projection through an opaque wrapper is not yet supported.

Additionally, StructBuilder::finish now accepts &InternSet<[Symbol]> directly instead of &Interner, Struct::new_unchecked is marked unsafe with documented safety requirements, all interpreter diagnostic severities are migrated from Severity::Bug/Severity::Error to Critical::BUG/Critical::ERROR, and comprehensive doc-examples are added across the interpreter value types (Dict, List, Struct, Tuple, Opaque, Ptr, Str, Num).

🔍 What does this change?

Introduces OrchestratorDiagnosticCategory with Interpret and Bridge variants, replacing the previous use of InterpretDiagnosticCategory::Suspension for bridge errors.
Adds BridgeDiagnosticCategory as the subcategory for suspension-fulfillment failures, replacing SuspensionDiagnosticCategory.
Removes SuspensionDiagnosticCategory and the Suspension variant from InterpretDiagnosticCategory.
Splits RuntimeError::into_diagnostic into into_diagnostic (identity category mapping) and into_diagnostic_with (caller-supplied category mapping), allowing the orchestrator to lift interpreter diagnostics into its own hierarchy.
Changes InterpretDiagnostic default severity kind from Severity to Critical, and migrates all diagnostic constructors from Severity::Bug/Severity::Error to Critical::BUG/Critical::ERROR.
Makes Struct::new_unchecked unsafe, documenting that callers must ensure fields are sorted; updates all call sites with unsafe blocks and safety comments.
Strengthens Struct::new to also reject unsorted field slices.
Changes StructBuilder::finish to accept &InternSet<'heap, [Symbol<'heap>]> instead of &Interner, narrowing the dependency.
Adds a mir/interpret compiletest suite that runs the interpreter and captures MIR as a secondary output.
Adds an initial interpreter test (access-struct-through-opaque) that documents the current limitation of projecting through opaque wrappers.
Exposes ReifyDiagnosticCategory, ReifyDiagnostic, and ReifyDiagnosticIssues publicly and adds MirDiagnosticCategory::Reify variant.
Adds Opaque::into_value, From<Symbol> for Str, and TryCloneIn for Str.
Adds #[inline] annotations and comprehensive doc-examples across interpreter value types.

🛡 What tests cover this?

New mir/interpret compiletest suite with access-struct-through-opaque as the first test case, covering the interpreter pipeline end-to-end.
Existing StructBuilder unit tests updated to use the new finish signature.
Existing interpreter unit tests updated for unsafe Struct::new_unchecked call sites.

❓ How to test this?

Run the compiletest suite targeting mir/interpret.
Confirm the access-struct-through-opaque test produces the expected stderr output showing the interpret::type-invariant diagnostic.
Run the existing MIR interpreter unit tests to confirm no regressions.

PR Summary

Medium Risk
Diagnostic type and category changes ripple through eval/orchestrator and compiletest; struct invariants and finish signature updates are widespread but mechanical.

Overview
Adds a mir/interpret compiletest suite that lowers through post-inline MIR, runs the interpreter (suspensions still unimplemented!()), and records MIR as a secondary artifact. The first UI test documents a known failure when projecting struct fields through an opaque wrapper.

Orchestrator diagnostics are split from interpreter diagnostics: bridge/PostgreSQL failures use OrchestratorDiagnosticCategory (Interpret vs Bridge) instead of InterpretDiagnosticCategory::Suspension. RuntimeError::into_diagnostic_with lets the orchestrator lift interpreter errors into that hierarchy; run_in now returns OrchestratorDiagnostic.

Interpreter ICEs move to Critical::BUG / Critical::ERROR. Struct::new_unchecked is unsafe with sorted-field invariants; StructBuilder::finish takes &InternSet (call sites use interner.symbols). Reify diagnostics are public under MirDiagnosticCategory::Reify, plus doc examples and small value-type API additions (Opaque::into_value, Str cloning).

Pull request overview

This PR wires the MIR interpreter into the compiletest harness for end-to-end execution tests, and refactors diagnostic category/severity plumbing so orchestration-layer (“bridge”) errors are no longer conflated with interpreter diagnostics. It also tightens/clarifies interpreter value invariants (notably struct field ordering), adds an initial mir/interpret UI test, and expands docs/examples across interpreter value types.

Changes:

Add a new mir/interpret compiletest suite that runs MIR through the interpreter and emits MIR as a secondary .mir output.
Introduce an orchestrator-level diagnostic category (OrchestratorDiagnosticCategory) that cleanly distinguishes interpreter errors from bridge (PostgreSQL suspension) failures.
Harden interpreter value APIs (e.g., Struct::new_unchecked becomes unsafe, Struct::new rejects unsorted fields; StructBuilder::finish takes &InternSet<[Symbol]>) and expand doc-examples/inline hints.
