Reframe a series from "ordered chapters that own pages" to ONE flat, series-global ordered run of pages with optional cosmetic chapter DIVIDERS over it. A chapter no longer wraps content — it's a labeled divider anchored to the page that begins it; a page's chapter is derived as the nearest preceding divider. This is what lets installments assembled from multiple sources sit in one continuous, correctly-numbered sequence (operator's Goblin Juice case). - migration 0047: flatten each series to a series-global page_number (preserving today's reading order); convert each existing chapter to a divider anchored at its first page (keeping title/stated_part); drop series_page.chapter_id; reshape series_chapter (anchor_page_id UNIQUE FK, drop chapter_number/is_placeholder/stated_page_start/end). Loss-safe for content; drops empty placeholder chapters + a redundant page-1 divider. - series_page: page_number is now the series-global order; no chapter_id. - series_chapter: anchored divider (anchor_page_id, title, stated_part). - series_service: flat list_pages (one run + derived dividers + per-page source_post + part_gaps), series-wide reorder/renumber, divider CRUD (create/update/move/delete); retired per-chapter reorder/merge/placement. - api/tags: drop chapter_id from add; /chapters endpoints are divider create/update/delete (removed chapter reorder/merge/page-reorder). - series_match_service: series "end" reads max(series_page.stated_page); accept appends via add_post. tag_service series-merge appends src's pages after tgt's max so the merged series stays one clean run. - frontend: seriesManage store + SeriesManageView → one continuous drag-reorder grid with inline divider bars + series-global page numbers; reader walks the flat run, headings from dividers; PostSeriesMenu copy. - tests reworked across the series suite for the divider model. Phase 2 (pending staging for add-from-post) is separate. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

"""SeriesPage — ordered image membership for a series-kind Tag.
|
|
|
|
A series IS a Tag with kind='series'; series_page gives it a SINGLE flat,
|
|
series-global ordered run of pages (FC-6.x divider reframe). An image belongs to
|
|
at most one series (UNIQUE image_id). Reading order is `page_number` alone — a
|
|
series-wide ordering key (not unique), rewritten 1..N wholesale on reorder so a
|
|
reorder can't transiently collide on an index.
|
|
|
|
Chapters are cosmetic DIVIDERS anchored to a page (see SeriesChapter); they do
|
|
NOT own pages, so there is no chapter_id here — a page's chapter is derived at
|
|
read time as the nearest preceding divider. stated_page carries the printed page
|
|
number parsed from the source post, nullable when unknown.
