Story 5.5: Subtotals & Grand Total
As a CalcPad user, I want subtotal lines scoped to their respective sections and a grand total that sums all subtotals, So that I can build structured documents like budgets with section summaries and an overall total.
Acceptance Criteria:
Given a sheet with two sections, each ending with a subtotal line
When the engine evaluates the sheet
Then each subtotal computes the sum of numeric lines in its own section only (not lines from other sections)
Given Section A has values 100, 200 (subtotal = 300) and Section B has values 50, 75 (subtotal = 125)
When the user writes grand total after both sections
Then the result is 425 (the sum of all subtotal lines: 300 + 125)
Given a sheet with three sections, each with a subtotal
When the user adds a fourth section with its own subtotal
Then grand total at the bottom automatically includes the new subtotal in its sum
Given a subtotal line exists but its section has no numeric lines
When the engine evaluates
Then the subtotal is 0
And the grand total still includes this 0 subtotal without error
Given a section uses total instead of subtotal
When a grand total line appears later
Then grand total sums all subtotal lines specifically (it does not include total lines unless they are explicitly subtotal-scoped; the distinction should be clearly documented)
Given a user writes multiple subtotal lines within the same section
When the engine evaluates
Then each subtotal line sums the lines above it within its section scope, and grand total sums all subtotal lines in the document
