可运行示例
作用：本仓库自研代码的最小可运行演示：每个 demo 自包含、只用手工或合成的小输入，并随附一次正确运行应产出的结果。
入口：03_telomere/run_demo.sh、05_centromere/run_demo.sh；每个 demo 的目录含 input/、expected_output/ 与 run_demo.sh。
输入：03_telomere/input/ 的 2 kb 合成染色体 FASTA 及其 .fai 索引；05_centromere/input/ 的 clusters.list（8 个重复簇）与 pairs.jaccard_ge0.7.tsv（6 条 Jaccard 对）。
输出：各 demo 的 work/，即本次运行的结果，用于与 expected_output/ 比较。
运行：bash demo/03_telomere/run_demo.sh；bash demo/05_centromere/run_demo.sh（脚本按自身位置定位仓库，可从任意工作目录调用）。
工具：只需 Python 3 解释器与标准库，不用第三方包、参考基因组或测序数据；两个 demo 都在 1 秒内跑完。

**Purpose**: Small, runnable demonstrations of this repository's custom code; each demo is self-contained, uses a tiny hand-made or synthetic input, and ships the output a correct run produces. **Entry point**: `03_telomere/run_demo.sh`, `05_centromere/run_demo.sh`; each demo directory holds `input/`, `expected_output/` and `run_demo.sh`. **Inputs**: the 2 kb synthetic chromosome FASTA and its `.fai` index in `03_telomere/input/`; `clusters.list` (8 repeat clusters) and `pairs.jaccard_ge0.7.tsv` (6 Jaccard pairs) in `05_centromere/input/`. **Outputs**: each demo's `work/` directory, holding the result of the current run for comparison with `expected_output/`. **Run**: `bash demo/03_telomere/run_demo.sh`; `bash demo/05_centromere/run_demo.sh` (the scripts resolve the repository layout relative to their own location, so they can be invoked from any working directory). **Tools**: only a Python 3 interpreter and the standard library — no third-party packages, no reference genome and no sequencing data; both demos run in under a second.| 步骤 | 内容 |
