Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-06 (score 67, +1)

No change was recorded against any check on this day. Stability & Change Management went from 33 to 37. That category is still filling its 30-day observation window: 10 days of observed history at the previous scan, 11 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (5)

### `saju_chart` (~400 tokens)

Korean Saju (Four Pillars / 四柱八字) natal chart with annotations. Returns the four pillars (year/month/day/hour) with their heavenly stems and earthly branches, the Ten Gods (十神) mapping, the five-element ratios, plus the Spirit Stars (神殺 / 신살) and Twelve Life Stages (十二運星 / 십이운성) annotations on each pillar. The foundational reading other tools build on. Use for 'show me my saju', 'what's my birth chart', '내 사주 봐줘'.

Input parameters:

- `birth` (string, required): Birth date & time, 12 digits YYYYMMDDHHMM (e.g. 199001151030). Use 1230 for unknown time.
- `gender` (integer, required): Gender — 0: female, 1: male (CAFE convention).
- `is_leap_year` (boolean): Optional. true if the lunar birth month is a leap month (윤달). Only meaningful with is_lunar=true.
- `is_lunar` (boolean): Optional. true if the birth date is a lunar-calendar date (default false = solar).
- `loc` (integer): Optional birthplace region ID for overseas births (24Plus world-city ID). Omit for Korea.
