Life Decision Tree

Turn what you already said about your own life into a decision tree you can act on. 把你说过的话，长成一棵能推演的决策树。

An Obsidian plugin. All data stays on your machine. 一个 Obsidian 插件，数据只在本机。

What it does · 它做什么

• Interview mode: 15 questions, then it builds 18 nodes / 3 branches from your own words. 访谈入库：15 道题，生成 18 个节点、3 条分支。
• One branch is intentionally locked, showing what evidence is still missing. 有一条分支会被锁住，写清「还差什么证据」。
• Three-layer memory: L1 raw words → L2 digest → L3 judgement, each traceable back to L1. 三层记忆可逐级追溯。
• Diagnosis states (诊断三态): what you already own, what needs re-checking, what needs more evidence.
• Everything local: .ldt/memory.json, .ldt/person-model.json, .ldt/run.json.

Disclosure · 披露（Obsidian developer policies require these to be stated clearly）

• Payment is required for full access. The plugin runs in a demo mode (one full generation, data isolated) until a licence code (SB-…) is entered. Codes are sold directly by the author; Obsidian does not process this payment. 付费才能完整使用：未填兑换码时是体验版（可完整生成 1 次），填码后解锁；款项由作者直接收取。
• Network use (optional). Only the optional AI enhancement feature calls the DeepSeek API, and only when you paste your own API key into settings. Nothing else leaves your machine. 可选联网：只有「AI 增强」会调用 DeepSeek，且必须你自己填 Key；其余全程离线。
• No account is required, no telemetry, no ads. 不需要账号、无遥测、无广告。
• Data stays under your vault's .ldt/ folder; delete my data wipes it after a backup. 数据在库目录 .ldt/，可一键删除（先备份）。

Privacy · 隐私

Everything is read/written locally. Export runs a redaction pass (phone / email / ID numbers) before producing a file. The plugin never opens files outside your vault.
