A paper is a document written against a template. Its structure is never copied into it: `paper` points at a template and the outline is read live on every render, so switching `template_id` re-shapes the whole document in one write. Sentences are addressed by *position* rather than by a template row id: `paper_sentence.paper_template_filed_sort` holds the sort of the placement the sentence belongs to, and `sort` holds its place inside that paragraph. That indirection is what makes a template switch non-destructive — a sentence that remembers "position 7" lands on whatever the new template puts at position 7 — and it is why a paragraph is any position either the template or the content mentions: the structure survives with no content, and content whose position the template does not define is still rendered, in order, under 未设定. Citations are a table rather than a column, since one sentence may quote several references. `quote` is required — a citation that does not say what it quotes is refused with 422 — while `reference_id` is a plain nullable integer with no foreign key, because the reference library does not exist yet. Deleting a template a paper is written against is refused with 409 and a count, matching how the field library refuses to drop a field still in use. scripts/smoke_papers.py walks the whole loop — create, empty structure, write a paragraph with citations, switch templates, keep unmatched positions, move a paragraph, delete — in 40 checks, and cleans up after itself.
