akibaandClaude Opus 4.8 2edb897000 feat(f3): viewport fit/centering math (fit-width / fit-page / center)
CI / Windows build (push) Has been cancelled
Details 
Extracts the untested ad-hoc arithmetic from pen_editor_screen._centerPage into
pure, shared, tested functions: fitWidthScale (fill viewport width — the
continuous-single default), fitPageScale (letterboxed min-axis fit), and
centerOffset (top-left translation to center scaled content; negative when it
overflows/scrolls). Powers the viewport's initial transform + the reader
fit-width/fit-page actions.

flutter analyze lib/editor clean; 228/228 tests (+5).

akibaandClaude Opus 4.8 1aa2865d6f feat(f2): two-page spread layout foundation (pair rows + row heights)
CI / Windows build (push) Has been cancelled
Details 
Book-like reading the user explicitly wanted: pairIntoRows groups pages into
two-up spread rows (optional coverAlone for a title page; trailing odd page sits
alone), spreadRowHeights fits each page to half the column and takes the tallest
per row (common baseline), and spreadStackMetrics stacks the rows so the
existing PageStackMetrics.visibleRange windows continuous-DOUBLE by ROW.

Pure geometry reusing the continuous-single layer; the row-mounting widget is
device-gated. Zero-rework-risk (not rendering).

flutter analyze lib/editor clean; 172/172 tests (+8).

akibaandClaude Opus 4.8 c31bfd3445 feat(p0.5): continuous-single navigation math (current-page + scroll clamp)
CI / Windows build (push) Has been cancelled
Details 
Extends PageStackMetrics with the navigation geometry continuous-single needs:
maxScrollExtent (last page bottom rests at viewport bottom, never negative),
clampScroll, and dominantPageAt — the page covering most of the viewport, which
drives the page-number indicator + thumbnail-grid highlight + jump-to-page (F4).
Pure; clamps past both ends; 0 for empty documents.

flutter analyze lib/editor clean; 129/129 tests (+6).

akibaandClaude Opus 4.8 1a3d1065f9 feat(p0.5): continuous-single page windowing math (step 10, automatable slice)
CI / Windows build (push) Has been cancelled
Details 
PageStackMetrics + PageWindow: the pure geometry that decides which pages are
mounted for a scroll position (windowed lazy hosting → 60fps on a 300-page doc,
R1). Pages stack vertically with cumulative tops (O(log n) binary-search
visibleRange); a viewport [scroll, scroll+extent) grown by cacheExtent on each
side selects the inclusive intersecting page band, half-open at page boundaries,
clamped to valid indices, empty for empty/over-scrolled-past documents, and
gap-aware (a scroll resting inside an inter-page gap shows no page).

Widget-free + pdfrx-free by design: the page-mounting widget and zoom-settle DPI
refresh are device-gated; only the windowing math is automatable, and it is here
with exhaustive unit coverage (boundaries, cache band, clamping, gaps, empty).

flutter analyze lib/editor clean; 115/115 tests (+13).
