Third release of the IS-BE architecture. This release reflects the framework adapted to the working principle established through development and training experience. Key additions since v1.1: Working principle: concepts grounded when reached through direct observation (author) and internally consistent (Claude AI) Temporal protection: separate section with critical discipline and warning message — provisional, subject to adaptation Personal notes section: observations outside framework construction Project review completed: grounded vs ungrounded discoveries separated Ungrounded discoveries collected in personal_note_002 What is solidly grounded: IS/BE methodology and working pattern L0 concepts: all, define L1 concepts: entropy, entity, rule — reached through direct observation L1 concepts: number, group — internally consistent, less thoroughly tested through direct experience What remains in progress: entity BE record pending revision add as BE label for group remains premature Several L1 records need further grounding Author's observation: inconsistency has proven to be the motor of evolution of the framework. Inconsistency is under control with the working principle respected. Author: 谢宇辰 (Yuchen XIE) License: CC BY-NC-SA 4.0
