Aug 1, 2025August 2025—pi-base/data: Delivered a major topology property taxonomy overhaul and fixed-point property expansion. Key changes include introducing a new fixed-point property for S159 (Right open-ray topology) as part of issue #1400, and mapping S159 to P89/P000089. Renamed and reorganized property IDs from P000123 to P000155, removed obsolete files, and updated theorems. Documentation for the pseudo-arc space (S000127) was refreshed with new properties and refined descriptions. Completed local 1-Euclidean work (#1409) and updated S127 entries (#1379). This work improves consistency, maintainability, and future extensibility of the topology catalog, supports faster onboarding for contributors, and enhances discoverability for downstream consumers of the repository.
