-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Overview
-
-Vespertide is a Rust workspace for defining database schemas in JSON/YAML and generating migration plans and SQL from model diffs. It enables declarative schema management by comparing the current model state against a baseline reconstructed from applied migrations.
-
-The workspace uses Rust **edition 2024**.
-
-## Build and Test Commands
-
-```bash
-# Build the entire workspace
-cargo build
-
-# Run all tests
-cargo test
-

-
-# Run a single test
-cargo test -p vespertide-planner test_name
-
-# Run tests with output shown
-cargo test -- --nocapture
-

-## Architecture
-
-### Core Data Flow
-
-1. **Schema Definition**: Users define tables in JSON files (`TableDef`) in the `models/` directory
-2. **Baseline Reconstruction**: Applied migrations are replayed to rebuild the baseline schema
-3. **Diffing**: Current models are compared against the baseline to compute changes
-4. **Planning**: Changes are converted into a `MigrationPlan` with versioned actions
-5. **SQL Generation**: Migration actions are translated into SQL statements
-
-### Crate Responsibilities
-
-- **vespertide-core**: Data structures (`TableDef`, `ColumnDef`, `ColumnType`, `MigrationAction`, `MigrationPlan`, constraints, indexes)
-  - `ColumnType` enum with `Simple(SimpleColumnType)` and `Complex(ComplexColumnType)` variants
-  - `ColumnType::to_sql()` and `ColumnType::to_rust_type()` methods for type conversion
-- **vespertide-planner**:
-  - `schema_from_plans()`: Replays applied migrations to reconstruct baseline schema
-  - `diff_schemas()`: Compares two schemas and generates migration actions
-  - `plan_next_migration()`: Combines baseline reconstruction + diffing to create the next migration
-  - `apply_action()`: Applies a single migration action to a schema (used during replay)
-  - `validate_*()`: Validates schemas and migration plans
-- **vespertide-query**: Converts `MigrationAction` → SQL with bind parameters
-  - Uses `ColumnType::to_sql()` method for SQL type conversion
-- **vespertide-config**: Manages `vespertide.json` (models/migrations directories, naming case preferences)
-- **vespertide-cli**: Command-line interface implementation
-- **vespertide-exporter**: Exports schemas to other formats (e.g., SeaORM entities)
-  - Uses `ColumnType::to_rust_type(nullable)` method for Rust type conversion
-- **vespertide-schema-gen**: Generates JSON Schema files for validation
-- **vespertide-loader**: Loads migrations and models from filesystem (JSON/YAML)
-- **vespertide-naming**: Naming conventions and case conversion helpers
-- **vespertide-macro**: Compile-time migration macro (`vespertide_migration!`) for SeaORM
-- **vespertide**: Main crate that re-exports vespertide-core and vespertide-macro
-
-### Key Architectural Patterns
-
-**Migration Replay Pattern**: The planner doesn't store a "current database state" - it reconstructs it by replaying all applied migrations in order. This ensures the baseline is always derivable from the migration history.
-
-**Declarative Diffing**: Users declare the desired end state in model files. The diff engine compares this against the reconstructed baseline to compute necessary changes.
-
-**Action-Based Migrations**: All changes are expressed as typed `MigrationAction` enums (CreateTable, AddColumn, ModifyColumnType, etc.) rather than raw SQL. SQL generation happens in a separate layer.
-
-## Important Implementation Details
-
-### ColumnDef Structure
-When creating `ColumnDef` instances in tests or code, you must initialize ALL fields including the newer inline constraint fields:
-
-```rust
-ColumnDef {
-    name: "id".into(),
-    r#type: ColumnType::Simple(SimpleColumnType::Integer),
-    nullable: false,
-    default: None,
-    comment: None,
-    primary_key: None,      // Inline PK declaration
-    unique: None,           // Inline unique constraint
-    index: None,            // Inline index creation
-    foreign_key: None,      // Inline FK definition
-}
-```
-
-These inline fields (added recently) allow constraints to be defined directly on columns in addition to table-level `TableConstraint` definitions.
-
-### ColumnType Structure
-`ColumnType` is an enum with two variants:
-- `Simple(SimpleColumnType)`: Built-in types like `Integer`, `Text`, `Boolean`, etc.
-- `Complex(ComplexColumnType)`: Types with parameters like `Varchar { length }` or `Custom { custom_type }`
-
-**Important**: In Rust code, always use `ColumnType::Simple(SimpleColumnType::Integer)` instead of the old `ColumnType::Integer` syntax. The `From` trait is implemented for convenience:
-```rust
-// These are equivalent:
-ColumnType::Simple(SimpleColumnType::Integer)
-SimpleColumnType::Integer.into()
-```
-
-### ColumnType Methods
-`ColumnType` provides two utility methods:
-- `to_sql()`: Returns the SQL type string (e.g., `"INTEGER"`, `"VARCHAR(255)"`)
-- `to_rust_type(nullable: bool)`: Returns the Rust type string for SeaORM entity generation (e.g., `"i32"` or `"Option<i32>"`)
-
-These methods replace the old standalone functions `column_type_sql()` and `rust_type()`.
-
-### Foreign Key Definition
-Foreign keys can be defined inline on columns via the `foreign_key` field:
-
-```rust
-pub struct ForeignKeyDef {
-    pub ref_table: TableName,
-    pub ref_columns: Vec<ColumnName>,
-    pub on_delete: Option<ReferenceAction>,
-    pub on_update: Option<ReferenceAction>,
-}
-```
-
-### Migration Plan Validation
-- Non-nullable columns added to existing tables require either a `default` value or a `fill_with` backfill expression
-- Schemas are validated for constraint consistency before diffing
-- The planner validates that column/table names follow the configured naming case
-
-### SQL Generation Target
-SQL generation currently uses PostgreSQL-compatible syntax. The query builder can be extended to support other database systems.
-
-### JSON Schema Generation
-The `vespertide-schema-gen` crate uses `schemars` to generate JSON Schemas from the Rust types. After modifying core data structures, regenerate schemas with:
-```bash
-cargo run -p vespertide-schema-gen -- --out schemas
-```
-
-Schema base URL can be overridden via `VESP_SCHEMA_BASE_URL` environment variable.
-
-## Testing Patterns
-
-- Tests use helper functions like `col()` and `table()` to reduce boilerplate
-- Use `rstest` for parameterized tests (common in planner/query crates)
-- Use `serial_test::serial` for tests that modify the filesystem or working directory
-- Snapshot testing with `insta` is used in the exporter crate
-
-## Limitations
-
-- YAML loading is not implemented (templates can be generated but not parsed)
