#Test vectors

Deterministic portable fixtures for hold-and-win-reference. The vectors themselves are source-controlled in the backend, where they execute; this file is the index that names their identity and the commands that produce and check them.

#Vector identity

A vector is only replayable if it binds all of:

#Locations

#Generation

Seeds are discovered by search, not chosen by hand — the existing generator walks candidate seeds until one genuinely reaches each required scenario:

cd /Users/admin/kiro/backend
go test -tags parityseed ./libs/mathengine/parity/ -run TestDiscoverParityVectors -v

Expected values are then reviewed by hand and pinned as literals.

A failing vector is never "fixed" by re-running the generator. A mismatch means the reference and the runtime disagree, or that engine behaviour moved. Both require a decision.

#Required scenarios

• No win, no trigger
• Base line win without trigger
• Five BONUS — no trigger, zero feature draws
• Six BONUS — trigger with exact reel-major lock order
• Miss-only step decrements respins by exactly one
• Landed prize resets respins to three
• Mini, Minor and Major landed prizes
• Ordinary sum below the cap
• Ordinary sum capped once at 500×
• Full grid awarding exactly Grand 500×
• Duplicate step replay: identical result, zero new draws
• Persisted step execution equals RunHoldAndWinToCompletion
