# Math Derivation

建立诚实、可检查的推导链;不把解释、近似或数值现象伪装成严格证明。

## Position in the Method Map

本 skill 连接“规格与语义”到“演绎验证/定理证明”:它先保持 ProblemContract 的定义和量词不变,再将论证拆成可复核的中间命题。它不是 Lean elaboration,也不是自动化求解器;需要形式化 proof term 时转交 `math-formalization`。地图总览见 [`FORMAL-METHODS-MAP.md`](../../../governance/standards/FORMAL-METHODS-MAP.md)。

## When to Use This Skill

- 用户要求推导公式、整理理论线或解释等式来源。
- 当前公式混用了不同对象、极限、尺度或适用域。
- 需要将全局量分解为可解释项,或从一般模型收敛到可验证特例。

## Not For / Boundaries

- CandidateObservation 未形成明确用户目标或 active ProblemContract 时回到 `math-discovery`;不得用推导文本替候选完成准入。
- 完整定理证明交给 `math-proof`。
- 具体符号/数值检查交给 `math-computation`,其结果只是证据层。
- 不静默增加假设、交换极限/积分、忽略收敛条件或改变目标对象。

## Quick Reference

```text
Target:要得到什么,角色是 identity / proposition / approximation / interpretation?
Invariant object:贯穿推导的唯一顶层对象是什么?
Assumptions:显式、隐藏、局部、渐近和正则性条件。
Notation:每个符号先定义,一物一名。
Map:中间恒等式/引理、每步所用假设、近似进入位置。
Checks:维度、定义域、边界、极限、特例、符号与数值反算。
Status:coherent / coherent-after-reframing / blocked。
```

## Examples

### Example 1:精确恒等式
- 输入:需要证明两个代数表达式等价。
- 动作:固定定义域和变量假设,逐步变形,再交给 SymPy 做差为零检查。
- 验收:区分纸面推导与 `symbolically-checked`,不标记 kernel-checked。

### Example 2:渐近近似
- 输入:推导大样本近似。
- 动作:标明极限变量、余项、均匀性和常数依赖。
- 验收:结论含适用域和误差阶,不把近似写成恒等式。

### Example 3:目标对象错误
- 输入:局部代理量被当作全局目标。
- 动作:指出对象切换,重构为“全局量 → 分解 → 局部切片”。
- 验收:状态为 `coherent-after-reframing` 并保留原目标差异。

## References

- `references/source-map.md`:推导方法来源和未吸收边界。
- `references/pressure-tests.md`:隐藏假设压力场景。

## Maintenance

- Sources:`kdense-scientific-skills` 与本项目 ProblemContract/证据分层规则;不依赖未发布本机来源。
- Last updated:2026-08-13。
- Verification:`python3 scripts/smoke_math.py` 只验证计算层;推导仍需逐步审计。

catchup

Recovers prior coding-agent session context by running `catchup <agent> --since-compact`, which extracts a clean summary of a previous Codex, Claude Code, Antigravity, OpenCode, or Pi Agent session. Use when the user says "catch up", "what did the last session do", "get me up to speed", "I switched agents", or asks to recover/summarize a previous session before continuing. Do NOT use for the current conversation, git history, or any non-agent log.
