Impact ledger
Every decision and its outcome, in order. Each entry carries a SHA-256 hash of the entry before it, so changing any past entry breaks the chain. This page checks the chain each time it loads.
How the chain works
Each entry’s fields are written in a fixed order. Its hash is SHA-256 of the previous entry’s hash, a line break, and those fields. The first entry starts from 64 zeros. The server hashes the backtest with node:crypto; your browser re-checks it, and hashes its own decisions, with Web Crypto.
Decisions this session
Plans a person approved or rejected in the console. Kept in this browser only.
