Move the FK column fields String->Vec<String> through all six layers (AddRelationship/SqlForeignKey AST, RelationshipSchema, metadata, project.yaml, ReadForeignKey, RelationshipEnd). Metadata stores comma-joined lists in the existing TEXT cells; project.yaml endpoints now columns: [a, b] (house style). Executor logic is multi-column ready: resolve_fk_parent_columns (full-PK F-A + auto-expand F-D), per-pair type-compat, schema_to_ddl multi-column emission, pragma FK read grouped by id, auto-name + --create-fk per-column, multi-column teaching echo. Single-column behaviour preserved (one-element vecs); all 2181 tests green. The grammar to parse multi-column input lands next.

//! Integration tests for `runtime::enrich_dsl_failure`
|
|
//! (ADR-0019 §6).
|
|
//!
|
|
//! Each test:
|
|
//! 1. Bootstraps a real `Database` (in-memory).
|
|
//! 2. Constructs the schema/data needed to trigger one
|
|
//! class of engine error.
|
|
//! 3. Provokes the failure through the public Database API,
|
|
//! capturing the resulting `DbError`.
|
|
//! 4. Calls `enrich_dsl_failure` and asserts the
|
|
//! `FailureContext` carries the schema-resolved facts a
|
|
//! learner would expect to see in the rendered error.
|
|
//!
|
|
//! Pinpoint diagnostic-table presence is verified for the
|
|
//! UNIQUE INSERT case (the most pedagogically valuable
|
|
//! pinpoint today).
