# Galaxy Sports Edge — Proof API

> A verifiable, publish-before-kickoff record of calibrated sports-market signals. This document tells an AI agent how to independently verify that record and gives a machine-readable snapshot of what is substantiated enough to publish today.

## Record doctrine

- Every book-priced pick is committed to a tamper-evident, hash-chained receipt BEFORE kickoff — the claim is frozen before the outcome is known. A model-signal pick has no book price, carries no receipt, and is labelled as such.
- The judge is closing-line value (CLV) measured against the market's closing number, plus the settled result — not our own after-the-fact narration.
- A performance number renders only if it carries all four legs: a coverage denominator, a Wilson or Clopper-Pearson lower bound, CLV backing, and walk-forward provenance. Missing any leg, it is withheld, not shown.
- Publication is founder-gated and defaults OFF. Until it is on and a metric is substantiated, this surface publishes no record — and says so.

## Current published state

- Publication is OFF (founder-gated). The Glass Ledger is founder-gated behind the PUBLISH_LEDGER environment variable, which defaults off. No performance data is published while it is unset.

## Verify our record yourself

- Receipts are minted pre-kickoff and never rewritten; each is a SHA-256 content hash over a canonical payload.
- Receipts extend a hash chain, so any back-dated edit or dropped entry breaks the chain and is detectable.
- Independent recomputation is the design goal: the record is reproducible from the committed receipts and public closing lines, not taken on trust.

- [receipt-verify](https://www.galaxysportsedge.com/api/verify?hash=<64-hex-sha256>): Programmatic receipt check. Paste a pick's receipt hash; the stored payload is re-hashed live and compared to the frozen commitment. Pre-kickoff receipts return SEALED (existence + integrity + freeze time + model version only); post-kickoff/settled receipts open in full.
- [human-verify](https://www.galaxysportsedge.com/verify): Human-facing verification page for the same receipt check.
- [record](https://www.galaxysportsedge.com/proof): Proof-of-record surface: the published, substantiated track record (or an honest empty state until one exists).
- [receipts](https://www.galaxysportsedge.com/api/proof/receipts): Enumerable JSON list of every SETTLED pick receipt (paginated). Each row carries the leaf preimage so you can recompute its hash and verify it independently; pre-kickoff/unsettled receipts are never listed.
- [self](https://www.galaxysportsedge.com/api/proof/ledger): This document as JSON — the machine-readable ledger snapshot and verification map.
- [openapi](https://www.galaxysportsedge.com/api/proof/openapi.json): OpenAPI 3.1 contract for the read-only Proof API — import it to call these endpoints from any OpenAPI-aware tooling.
- [verification-spec](https://www.galaxysportsedge.com/api/proof/verification-spec.json): The trustless conformance spec: the exact hash-chain algorithm plus synthetic known-answer test vectors, so you can build your own verifier in any language and check us with zero trust in our code.

## Methodology & data rights

- [methodology](https://www.galaxysportsedge.com/methodology): How the engine scores signals and what the confidence numbers mean.
- [calibration](https://www.galaxysportsedge.com/calibration): Reliability / calibration track record once substantiated entries exist.
- [how-we-make-money](https://www.galaxysportsedge.com/how-we-make-money): Revenue model and disclosed-conflict affiliate posture.
- [data-rights](https://www.galaxysportsedge.com/data): Data sourcing and rights posture: facts only, attributed, rights-gated extraction.
- [responsible-play](https://www.galaxysportsedge.com/responsible-play): Limits and variance guidance. Signals are not certainty.

## What this service will never do

- Emit a performance number that has not passed the four-leg substantiation guard.
- Backfill or fabricate a track record, sample size, or win rate.
- Open a pick's committed fields (selection, price, confidence, edge) before kickoff — pre-kickoff receipts verify as SEALED, so verification can never be used to free-ride a paid pick.
- Present the market as beaten, or a result as certain. Signals are one input to a disciplined decision, never the decision.

## Optional

- [academy](https://www.galaxysportsedge.com/academy): Educational material on the methodology and terms used across the platform.
- [tools](https://www.galaxysportsedge.com/tools): Standalone calculators (EV, no-vig, parlay) usable independent of any pick.
- [podcast](https://www.galaxysportsedge.com/podcast): Episode archive discussing methodology and market context.
- [newsletter](https://www.galaxysportsedge.com/newsletter): Issue archive; same substantiation rules as every other public surface.
