	Pattern shape — fixed factor count per type. Numeric values intentionally match the engine's PatternType enum (MONTHLY=0, DAILY=1, HOURLY=2, WEEKEND=3) so casts to/from int are safe. More...

One PatternProvider per [PATTERNS] entry in the project. Owned by a project-scoped PatternRegistry. Acts as the single source of truth for that pattern: the editor dialog's grid, bar-chart preview, Object Browser property pane, and any DWF inflow picker all subscribe to the provider's Qt signals (per [[feedback_mvc_synchronized_uis]]).

Patterns are fixed-size dimensionless multiplier arrays whose count is determined by the pattern type:

• Monthly — 12 factors (one per calendar month)
• Daily — 7 factors (one per day of week, Sun … Sat)
• Hourly — 24 factors (one per hour of day, weekday)
• Weekend — 24 factors (one per hour of day, weekend)

SWMM's legacy convention is avg = 1.0 (sum = N), but the editor's normalize() lets callers rescale to any target sum (default 1.0 per the user-confirmed UX in Slice BQ Phase 6.7.2).

Mutations are intended to flow through QUndoCommand subclasses; this class is undo-stack agnostic and exposes the raw apply* methods.
