* /api/persona-db — 人格层右栏数据 (只读)
|

|
|
* 守护: 铸渊 · ICE-GL-ZY001
|
||
|
|
*
|
||
|
|
* 数据源:
|
||
|
|
* 1. 优先读 PORTAL_DATA_DIR/persona-db-snapshot.json (生产环境由部署时打包)
|
||
|
|
* 2. 回退 repo 内 persona-brain-db/seed-data/*.json (开发/演示用)
|
||
|
|
*
|
||
|
|
* 设计理念 (cc-004):
|
||
|
|
* 不直接连 GitHub 或 Notion API — 国内 2C2G 不稳, 也暴露主权.
|
||
|
|
* 一律走本地快照, 把不稳定性吞进部署管道.
