Purpose

Describe deterministic daily puzzles and weekly gauntlet behavior.

Requirements

Requirement: Daily Puzzle Determinism

Daily puzzles SHALL be generated from the date and registered daily-capable seeded spawners so the same date produces the same puzzle selection.

Scenario: Open today's daily

• WHEN the user starts the daily puzzle for a date
• THEN PuzzleTea creates or resumes the record named for that deterministic daily puzzle

Requirement: Daily Streak Progression

Daily completions MUST update streak and XP metadata according to saved completion history.

Scenario: Complete consecutive dailies

• WHEN the player completes daily puzzles on consecutive eligible dates
• THEN PuzzleTea records a continuing daily streak

Requirement: Weekly Gauntlet

Weekly gauntlets SHALL expose a deterministic 99-puzzle ISO-week ladder, unlock current-week slots sequentially, and allow completed historical slots to be reviewed.

Scenario: Current week unlock

• WHEN the user completes the active current-week puzzle
• THEN the next weekly slot becomes available up to slot 99

Scenario: Past week review

• WHEN the user opens a past week
• THEN PuzzleTea permits review of completed saves without unlocking new historical puzzles
