Diff the two states → List of changes -4. Generate DDL → CREATE / ALTER statements -5. Execute → Apply to database +1. Discover all [0-9]*.yaml files recursively → sorted by numeric prefix +2.

Passes. + +### In Progress +- (none — feature complete) + +### Blocked +- Python `_handle_no_migration_files` interactive prompt blocks automated migration testing (no `live` flag). Tests work around it by monkeypatching `input()`. + +## Key Decisions +- **Schema at query/migration time, not on model**: Models stay agnostic → one model works in N schemas without duplication. +- **Empty string = no schema = backward compat**: All existing code continues to work unchanged. Schema qualification only activates when explicitly set. +- **`Option` vs `Option` in QueryNode**: `Option` for interned performance, `None` = no qualification. +- **Composite key `(schema, name)` everywhere**: Enables correct diff across schemas. No schema = empty string matches "no schema" (no `CreateSchema` emitted). +- **`CREATE SCHEMA IF NOT EXISTS` is automatic**: Runner creates schema before tables when schema is non-empty and backend supports schemas. Not part of migration files (idempotent). +- **Per-op schema override**: Each operation can carry its own schema, allowing mixed-schema migration files (unlikely but supported). +- **Temporary DDLGenerator per change**: Used in `generate()`, `apply_files()`, `plan_files()` to switch schema context. Acceptable cost since migration ops are rare. +- **Python QuerySet delegates schema to Rust FFI**: `("schema", name)` op is stored in ops list and handled by Rust `build_plan()`. This means all SQL compilation is schema-aware with zero additional Python overhead. +- **Integration tests run in subprocess for Python**: The `ryx` package auto-initializes the pool from `ryx.toml` at import time. Python's conftest also inits a SQLite pool. PG tests must run separately via subprocess with `RYX_AUTO_INITIALIZE=0`. + +## Next Steps +1. Add `live=True` flag to Python `MigrationRunner` to skip interactive prompt in tests (feature gap). +2. Documentation update: multi-schema section in migrations.mdx, `.schema()` API reference. + +## Critical Context +- **Rust integration tests**: 76 unit + 2 integration (SQLite full pipeline + PG multi-schema). +- **Python integration tests**: 42 unit + 1 integration (PG multi-schema via subprocess). +- `diff_states()` matches tables by `(schema, name)` composite key. Two tables with same name in different schemas are treated as different tables. `CreateSchema` is emitted for schemas with non-empty string. +- `DDLGenerator.qn()` produces `"schema"."table"` when schema is non-empty and backend supports schemas. For MySQL/SQLite, `supports_schemas()` → `false` eliminates qualification at compile time. +- `QueryNode.with_schema(schema)` interns the schema name as `Symbol`. The compiler's `write_table_ref()` checks `node.backend.supports_schemas()` at compile time. +- Python `QuerySet.schema()` adds an op that the Rust FFI `build_plan()` converts to `node.with_schema()`. The same Rust compiler handles qualification. +- `__main__.py` has two parser code paths: the old argparse-based `_build_parser()` and the new registry-based `build_parser()`. `--schema` was added only to `_build_parser()` for now. +- `inspectdb.py` hardcodes `table_schema = 'public'` for PostgreSQL introspection (the `--schema` flag passes through to the runner layer). +- Integration test requires a running PostgreSQL on localhost:5432 with user `einswilli` (no password) and a `ryx_integration_test` database. +- Python `ryx` package has `ryx/__init__.py:_auto_setup()` that reads `ryx.toml` and initializes the pool at `import ryx` time.
