| 38 hours | Stabilize one-core set proofs | adelon | |
| 3 days | Align successor with canonical set insertion | adelon | |
| Exact definitions remain named globals, so suc spells the canonical construction directly to coalesce with the packaged successor. | |||
| 3 days | Separate ordered tuples from PairSet | adelon | |
| 3 days | Rewrite protected set and naturals closure | adelon | |
| 2026-07-03 | Track ownership of top-level symbols | adelon | |
| Require every ownable top-level symbol to be introduced by a dedicated owner before it can appear in facts. Reject duplicate ownership and prevent symbols used by inductive definitions from being defined later. Use the ownership/dependency information to reject hidden recursive inductive definitions and to generate referenceable inductive principles. BREAKING CHANGE: Top-level facts no longer introduce symbols implicitly. | |||
| 2026-04-12 | Make handling of local variables stricter | adelon | |
| 2025-07-16 | Add quantified calcs and relax tokenization | adelon | |
| Use an `\iff`-calc to speed up `union_as_unions`. Also remove `in_implies_neq` which seems to interact badly with the choice axiom used by superposition-based proofs like Vampire in cut-down problems. | |||
