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
