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>

固体表面没有"流动补缺"这条退路。从物理上讲，"创造新表面"与"拉伸已存在表面"在固体中是两件独立的事，对应两个不同的物理量——表面能 $gamma$ 与表面应力 $f$。本节先把这二者分清，再把缺键模型 @缺键一般式 中的摩尔汽化热替换为摩尔升华热，得到固气界面的 $gamma_(S G)$。最后讨论 $gamma_(S G)$ 的晶面各向异性以及不同物质的 $gamma$ 量级谱。
