## What's Complete
|
||
|
|
|
||
|
|
- Parser, lexer, syntax support
|
||
|
|
- Type system and elaboration
|
||
|
|
- Chase algorithm with equality saturation
|
||
|
|
- Tensor algebra for axiom checking
|
||
|
|
- SMT-style model enumeration
|
||
|
|
- Persistence and version control
|
||
|
|
- Interactive REPL
|
||
|
|
- Comprehensive test suite
|

## Mostly Complete
|
||
|
|
|
||
|
|
- Parameterized theories
|
||
|
|
- Nested instances (parsing done, elaboration partial)
|
||
|
|
- Query optimization
|
||
|
|
- Relational algebra compilation
|
||
|
|
- Congruence closure integration

## Known Gaps
|
||
|
|
|
||
|
|
### TODOs in Code
|
||
|
|
|
||
|
|
| Location | Description |
|
||
|
|
|----------|-------------|
|
||
|
|
| `src/repl.rs:84` | Store full theory_type in GeologMeta |
|
||
|
|
| `src/overlay.rs:380` | Copy functions (deferred) |
|
||
|
|
| `src/store/query.rs:61` | Columnar batch loading |
|
||
|
|
| `src/store/instance.rs` | External references, product domains |
|
||
|
|
| `src/query/to_relalg.rs` | Column path navigation, ScanRelationOp |
|
||
|
|
|
||
|
|
### Incomplete Features
|
||
|
|
|
||
|
|
- Product types in conclusions don't fully work
|
||
|
|
- Existentials over product sorts unsupported
|
||
|
|
- Field projections in equations don't compile
|
||
|
|
- Disjunction fires both branches (correct but inefficient)
|
||
|
|
- Tensor compilation failures are silent
|
||
|
|
|
||
|
|
### In Progress
|
||
|
|
|
||
|
|
- Lean4 formalization of monotonic submodel proofs
|
||
|
|
- Homoiconic query plan representation
|
||
|
|
- Disjunction variable alignment for tensor builder
|
||
