v1.0.0

v1.0.0 (2026-10-08)

• 1.0: Phases 6 through 9 are complete and the Soulver-depth surface
  is whole - arithmetic with implicit multiplication, every
  percentage form including the reverse questions in words,
  functions with recursion and dimension-checked unit paths,
  self-updating line references, dates, recurring amounts, currency,
  units, math functions, tags, mixed lines, completion, and the
  template menu.
• Ctrl+click a math line and it explains itself: a popover shows the
  line's operations bottom-up, each as operands = value, evaluated
  in full sheet context so variables, references, and function
  bodies resolve. A relative percent reads in the sheet's words
  (200 + 15% (of 200) = 230). Unit lines and prose do not break
  down.
• Task lists: a list line may open with a GFM checkbox
  (- [ ] plan the trip); Ctrl+clicking the box toggles it as a
  plain user edit undo reverses. Checkboxes never enter the math.
• The region model: within each heading region, scalar answers
  align on the decimal point - integer answers pad so their implied
  dot sits where the region's fractional dots are. Quantities,
  errors, hex and bin keep their shapes.
• Definition sheets read as a table: the Outline popover lists every
  bound name beneath the headings; picking one lands on its line,
  with the answers column as the values and trailing comments as
  the notes.
• The template menu grows to four: budget (now with budget-vs-
  actual paired *_actual variables and a variance section where
  positive means under budget), portfolio, trip (dates for the
  countdown, rates for per-day costs, currency for the spend), and
  a Complex Sample - a scientist's worksheet running the ideal gas
  law, Arrhenius activation energy, triplicate statistics with a
  sample standard deviation, a dilution, Henderson-Hasselbalch pH,
  projectile range, and combinatorics through recursive functions.
• Two engine primitives the new sheets demanded: the prelude's math
  functions route to the unit engine (sqrt(144) is 12,
  sin(30 deg) is 0.5 - before, log(100) silently answered 100
  through the mixed skeleton), and quantity totals finish inside
  expressions (whole = total over money answers 990 EUR). Date
  words call their functions mid-line too: today + 30 days.
