Real-content fixture for the end-to-end pipeline. TH-141 (39 parts: 22 segment, 15 lemma, 2 example) migrated from the prototype's typst `#let parts` manifest to ADR-0008: declarative manifest.toml (project+info+ordered parts+targets) + per-element element.toml (kind + scalars; examples carry `source`). Content .typ files copied byte-identical (no math corruption); per-element main.typ + meta.toml dropped (wiring is now generated). Part order matches source exactly; 5 lemmas have no proof.typ (optional); no cross-file imports / paralearn refs / figs. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

某油井内未抽出的石油温度 $100 thin "℃"$，密度为水的 $80%$、比热容为水的 $60%$，记此为参考态。混合物表面张力系数

$ sigma \/ (10^(-3) thin "N/m") = 60 + 0.065 thin T \/ "K" - 24.0 thin p \/ "bar" + 3.15 thin (p \/ "bar")^2 . $

参考态下 $p$ 与 $T$ 成正比，比例系数为等容压强系数 $beta = 7.28 times 10^(-3) thin "bar/K"$。

某区域原本充满参考态石油，抽出一半的同时等体积注入水，混合后总体积等于两者之和，抽注过程绝热。问为使混合物 $sigma$ 最小，注入水的温度应为多少 ℃。
