The record remembers.

The integrity ledger records protocol events for a synthetic operator. It is illustrative, non-credit, non-regulatory, and scoped to committed artifacts.

A failure should remain visible.

Reputation

Memory boundary

One deterministic alpha scoring model. It is not credit, legal scoring, or a claim about real suppliers.

Omission challenge: -100Non-credit score

Reference score901

Starts at 1000. Floor 0, cap 1100 for the alpha model.

Events3

Each event references deterministic protocol artifacts.

Protocol versionv0.1

Weights are deterministic and documented.

Score 1000

Illustrative non-credit score initialized for the public alpha.

This is an illustrative non-credit, non-regulatory alpha reputation signal, not a universal score.

Formula

Successful material omission challenge -100, successful signed undisclosed-incentive evidence -200, hard-constraint violation -250, stale selected quote -75, finalized unchallenged receipt +1. Recovery is intentionally slow and does not erase prior failures.
