§21 and §22, each state its own screen rather than a variant of one. Which one
applies is decided by CycleStatusRules in a pure module with twelve tests on its
boundaries — and the boundaries are the point, because they are the days this
screen is most read: the day a period is due, the day after one ends, the day a
forecast slips.
The number dominates (§38): displayLarge at 72sp, in the primary colour, with
the unit as a separate quiet line so "4" reads instantly and "DAYS" is there if
you look. Its content description carries the whole sentence, so TalkBack says
"Period likely in: 4 days" rather than reading a bare numeral.
The state this screen exists to get right is the last one. Past the forecast the
app NEVER says late — late implies a schedule the user failed to keep, and the
truth is that an estimate was imprecise. It shows what it originally said, what
it says now, and asks.
A UX DEFECT FOUND BY DRIVING IT
Tapping "Period ended" changed nothing on screen. The logic was right — a period
that ends today still includes today, so the state does not change — but the
button looked broken, which is worse than being broken somewhere visible.
DuringPeriod now carries the end date, so the screen shows "Ended 18 August" and
offers only the useful action (undo) rather than a button that visibly does
nothing. §24's "Updated ✓" acknowledgement is there too. No test would have
caught this; it needed somebody to tap the button and look.
The banner slot is reserved and empty. §48 wants no layout jump when an ad loads
and a graceful gap when one fails, and both are properties of the space existing
whether or not it is filled — reserving it in Batch 07 instead means shipping
the jump first. Deliberately not a "your ad here" box, which would be a
placeholder for the thing a user pays to remove.
Fertility lines are absent rather than faked: §22 shows them and Batch 04
estimates them, and a placeholder number there would be inventing a fertility
estimate, which is the one thing this screen must not do.
Preview pairs for every state, light and dark. 129 tests, all passing.
