User Flows
FRD6 – Create discount flow, listing/search/filter flow, edit discount flow, delete discount flow

Functional Logic
FRD6 – Code validation (uppercase A-Z and 0-9, 3–20 chars, unique, no reuse of deleted codes, Random button generates unique valid code); Discount Type toggle (Percentage 1–100% / Fixed $); Duration field (independent from Valid Period, value + unit); Valid Period (Valid From, Valid To – end > start); Status logic (Active: today within valid period; Expired: past Valid To; Scheduled: Valid From in future); Redemption counter increments per subscriber use; Edit field-lock rules (Code always locked, Type always locked, Amount locked if redemptions ≥ 1, Valid From locked if currently Active); Delete behavior (existing subscriber discounts honored until duration ends; deleted code still visible in Reports; code cannot be reused)

Acceptance Criteria
FRD6 – Create form opens; valid code saves and appears in listing; code < 3 chars, > 20 chars, lowercase, special chars → inline errors; duplicate active or deleted code → inline error; Random generates valid unique code each click; Percentage/Fixed toggle works; Amount validation per type; Duration and Valid Period save independently; listing shows correct columns and status badges; Edit opens with all fields pre-filled; field-lock rules enforced; Delete confirmation shows retention message; deleted code disappears from listing; subscriber retains discount until duration ends; deleted code appears in Reports with usage data; deleted code cannot be reused

Edge Cases
FRD6 – Code exactly 3 chars → valid; code exactly 20 chars → valid; 100% percentage discount → valid; Duration 0 → error; Valid To before Valid From → error; Empty required fields on save → inline errors per field; no discounts exist → empty state 'No discounts found. Create your first discount.'
