Status History

Chronological record of every TECT pillar tier change (promotion, demotion, split, rollback). The current scoreboard is on the Status page; this History page shows how it got there. Each entry corresponds to an explicit pillar_status.json + Math note + CHANGELOG triple-write per the atomic-write rule (CLAUDE.md §3).

Source of truth: Docs/status/STATUS-HISTORY.md (canonical). This page is auto-generated from that source via Codes/tools/generate_status_history.py.
