Replay evidence, not guesswork
One replay. A match you can review.
Upload one Heroes of the Storm replay. The Rust Worker decodes it in memory and stores a derived bundle behind an unguessable link. The match page shows the roster, timeline, schematic positions, camps, win-probability estimate, and costly deaths.

From upload to match page
Clear steps. Explicit limits.
The Worker validates and decodes the replay, then stores one derived bundle for the match page.
Decode once
The Rust Worker produces a versioned bundle: roster, deaths, camps, win probability, and coverage.

What this page is not
Evidence first. No invented coaching.
- No client-side decoding. No WASM runs in the browser and no replay is decoded client-side.
- No battleground artwork. The schematic map plots raw MapGrid positions only.
- No causal claims. Death context is an observed association, never a claim that a death caused a loss.
- No LLM text. Every sentence comes from a deterministic template.
