// CORE PROPOSITION
We do not display data. We verify whether the model acting on it has converged on signal — or is memorizing noise.
// EXECUTIVE SUMMARY
What it is
Model-risk validation layer. SPORTINDEX provides independent model-risk validation for quant funds and market-makers — spectral audit, signal validation, and counterparty-grade research workflows.
Who it is for
Quantitative counterparties. Designed for quantitative funds, institutional allocators, family offices, research desks, trading/risk teams, and strategic counterparties.
How it integrates
Controlled API & audit artifacts. Delivered via controlled access, documented API schemas, audit-ready outputs, and NDA-governed validation materials.
What is under NDA
Full validation metrics. Full validation metrics, methodology details, model documentation, counterparty packages, and deeper performance evidence are disclosed only to verified institutional reviewers.
// INSTITUTIONAL AUDIT — DETERMINISTIC GATING LAYER
SPORTINDEX™: The Institutional Audit for Quantitative Capital
We don't build your strategy. We audit its mathematical integrity at each update and monitor its live behaviour for drift.
// FAILURE MODE — WHY MOST ENGINES DECAY
Most sports trading engines eventually fail due to Model Drift and Overfitting.
They begin to see "patterns" in random statistical noise, leading to catastrophic capital erosion.
Model drift: undetected
Overfit signal: indistinguishable from noise
Result: capital erosion
// OUR ROLE
The Deterministic Gating Layer.
SPORTINDEX™ combines two layers: a periodic spectral audit of your model weights — applying the WeightWatcher methodology (Dr. Charles Martin, JMLR) — run at each model retrain or update to certify structural health, and continuous drift & calibration monitoring of live inputs and predictions against that baseline.

// STEP 02 — SPECTRAL ANALYSIS
Spectral Validation
Layer A — periodic spectral audit: at each model retrain or update we analyze your model's weights spectrally — the heavy-tailed α-exponent under the WeightWatcher methodology — to certify whether it has converged on signal or is memorizing noise. This sets the stability envelope your live signals are gated against.

// STEP 03 — DETERMINISTIC STOP
The Red Line
Layer B — continuous monitoring: each live signal is designed to be checked against the calibrated baseline using input-drift, prediction-calibration, and edge-decay metrics. If predictions drift away from the validated baseline, the system is designed to trigger a deterministic stop.

Like a Patek Philippe movement, we represent the absolute standard of internal precision. While your engine generates the "alpha," we ensure the mechanics are flawless.
"Stop trading hallucinations. Start auditing your intelligence."
// CORE PROPOSITION
Spectral integrity is the precondition of edge. Audit before alpha.
// VERIFIED METHODOLOGY
Transparent Validation Framework
Auditable signal generation. Walk-forward backtesting. Institutional Performance Standards calibration. Process disclosed; figures available under NDA.
Backtest Protocol
Walk-forward validation with strict out-of-sample partitions. Period boundaries and dataset size disclosed under NDA.
Calibration Metrics
Expected Calibration Error (ECE), Brier Score, Sharpe Ratio computed per Institutional Performance Standards. Methodology reproducible.
Risk Controls
Drawdown caps, fractional Kelly sizing, Monte Carlo stress-testing across 10,000 iterations per signal class.
Audit Trail
Every signal logged with α-value, timestamp, and spectral stability flag. Reproducible on authenticated request.
Quantitative performance figures, audited backtest results, and risk factors are available under NDA following counterparty verification. Past performance is not indicative of future results. SPORTINDEX does not provide investment advice.
// VERIFIED METHODOLOGY
We do not ask for trust. We test on unseen data, measure precision against global standards, and record every step — so you can verify it yourself.
// INSTITUTIONAL FRAMEWORK
Validation Protocol, Edge Origin & Counterparty Eligibility
Three orthogonal disclosures: how the validation layer is tested, where the structural edge originates, and which counterparties qualify for access. Quantitative envelopes remain NDA-gated.
// SUBSECTION A — VALIDATION PROTOCOL
Methodology Disclosure
Structural parameters of the validation regime. Specific in-sample/out-of-sample splits, signal counts, and walk-forward windows are disclosed to verified counterparties under NDA per #methodology terms.
// PROTOCOL 01 — TEMPORAL DESIGN
Walk-Forward Validation
Strict temporal separation between training, validation, and out-of-sample windows. No look-ahead bias permitted. Window length, step size, and re-fit cadence are disclosed under NDA. Out-of-sample-only signal release governs production deployment.
Strict TemporalNo Look-Ahead
// PROTOCOL 02 — SAMPLE GEOMETRY
Per-League Signal Universe
Sample sizes scoped per league (NBA, MLB active; NHL, NFL Phase 2). Signals counted at game-resolution and event-resolution levels. Quantitative figures (signal counts, coverage %, validation pass rates) provisioned under NDA only.
Per-League ScopedMulti-Resolution
// PROTOCOL 03 — RECALIBRATION
α-Triggered Re-Fit
Recalibration cadence is event-driven, not calendar-driven. Spectral envelope excursion outside the documented stability band triggers model quarantine and re-fit. Calendar-only recalibration is rejected as a source of regime-detection latency.
Event-Drivenα-Triggered
// PROTOCOL 04 — REGIME SEPARATION
Live vs Backtest Demarcation
Live signal performance and backtested performance are tracked, audited, and disclosed as distinct regimes. Cross-regime aggregation is prohibited in counterparty reporting. Simulated performance disclosures accompany backtest figures per applicable regulatory standards.
Regime-SeparatedNo Cross-Aggregation
// SUBSECTION B — EDGE ORIGIN
Value Architecture
Structural origin of the validation edge. Described in microstructure terms; magnitude, persistence, and capacity are NDA-gated. No return claims are made or implied on this surface.
// EDGE SOURCE 01 — STRUCTURAL MISPRICING
Public-Overreaction Asymmetry
Retail-driven order flow exhibits documented asymmetric reaction to narrative events (injury reports, revenge-game framing, recency-weighted streaks). The validation layer identifies divergence between this flow and the underlying Poisson + Elo + xG/xA distribution. Edge magnitude and decay are disclosed under NDA.
Anti-NarrativeBayesian
// EDGE SOURCE 02 — LIQUIDITY FRAGMENTATION
Cross-Venue Microstructure
L3 order book signals across venues exhibit non-uniform price discovery latency. Sharp-money flow detection (#bento) operates on these inter-venue dislocations. The structural feature is venue-fragmentation; the engine extracts signal from the fragmentation surface, not from any single venue's quote.
L3 Order BookCross-Venue
// EDGE SOURCE 03 — LINE MOVEMENT TOPOLOGY
Opening vs Closing Inefficiency
The opening-to-closing line trajectory encodes the integration of public flow versus sharp money. The validation layer measures the topology of this trajectory — not the endpoint — to differentiate model-error edges from public-overreaction edges. Steam-move detection feeds the spectral filter.
Steam DetectionTopology-Based
// EDGE SOURCE 04 — REGIME-AWARE COMPRESSION
Spectrally Verified Signal Density
Spectral stability constrains the model class admitted to production. Models inside the documented stability envelope yield signal density consistent with implicit self-regularization theory. The structural source of the edge is therefore the model-selection regime, not opportunistic curve-fitting.
α-ConstrainedSelf-Regularized
// SUBSECTION C — COUNTERPARTY ELIGIBILITY
Eligibility Framework
Access is gated by regulatory qualification, not by application volume. The framework below extends the AUM ≥ $10M threshold disclosed in the NDA Portal with applicable per-jurisdiction regulatory categories.
// CATEGORY 01 — UNITED STATES
Qualified Purchaser / Qualified Institutional Buyer
Counterparties domiciled in the United States must satisfy QP status under Section 2(a)(51) of the Investment Company Act of 1940 or QIB status under Rule 144A. Verification is conducted manually following first contact via #nda.
QP §2(a)(51)QIB Rule 144A

Professional Client / Eligible Counterparty
Counterparties under FCA jurisdiction must satisfy Professional Client (per se or elective) or Eligible Counterparty classification under MiFID II / FCA COBS 3. Retail clients are not eligible. Categorization evidence is collected during onboarding.
FCA COBS 3MiFID II
// CATEGORY 03 — EUROPEAN UNION
Professional Investor (MiFID II)
EU-domiciled counterparties must satisfy Professional Investor classification under MiFID II Annex II. ESMA Guidelines on the appropriateness assessment apply. Cross-border distribution is conducted only via reverse solicitation or a registered partner per #compliance.

Sophisticated Counterparty Determination
For counterparties outside the US, UK, and EU, an equivalent sophisticated-investor determination is conducted per the local regime (e.g., MAS Accredited Investor in Singapore, ASIC Wholesale Client in Australia, FINMA Qualified Investor in Switzerland). Non-equivalent jurisdictions are declined.
Per-JurisdictionEquivalence-Tested
// SUBSECTION D — INTEGRATION WORKFLOW
Signal Emission & Counterparty Execution Boundary
Four-stage handoff protocol. SPORTINDEX validates and emits; counterparty retains full control over sizing, execution, and venue selection. The boundary is architectural, not contractual.
// STAGE 01 — SIGNAL EMISSION
Validated Signal + Edge Metric
Upon α-convergence within documented operating band [NDA], the validation layer emits a spectrally verified signal accompanied by a computed edge metric. No stake recommendation, no execution instruction, no allocation guidance. The output is data, not advice.
α-GatedEdge Metric Emitted
// STAGE 02 — COUNTERPARTY SIZING
Local Risk Engine
Counterparty applies internal sizing logic (fractional Kelly, drawdown caps, portfolio constraints) to the emitted edge metric using their own risk framework. SPORTINDEX does not size, allocate, or manage counterparty capital, and has no visibility into counterparty position state.
Counterparty-ControlledNo Capital Touch
// STAGE 03 — VENUE SELECTION
Execution Autonomy
Counterparty selects execution venue(s) per their own liquidity access, jurisdictional permissions, and counterparty agreements. SPORTINDEX maintains no execution endpoint to bookmakers, exchanges, or other venues, and exercises no role in order routing.
Venue-AgnosticNo Execution API
// STAGE 04 — AUDIT RECONCILIATION
Optional Post-Trade Logging
Counterparties may optionally reconcile executed outcomes against emitted signals for independent performance attribution. Full audit trail (α value, emission timestamp, spectral filter version) is provisioned to authenticated counterparties under NDA.
Opt-In ReconciliationNDA-Gated Trail
The disclosures above describe (a) the structural design of the validation protocol, (b) the microstructural origin of the edge, (c) the regulatory eligibility framework for counterparty access, and (d) the operational boundary between SPORTINDEX signal emission and counterparty execution. SPORTINDEX emits validated signal data and edge metrics only; sizing, execution, venue selection, and capital allocation are performed exclusively by the counterparty. None of the foregoing constitutes investment advice, an offer to sell or a solicitation of an offer to buy any security or financial instrument, or a representation as to expected returns. Quantitative envelopes — including window lengths, signal counts, recalibration thresholds, edge magnitudes, capacity allocations, and per-jurisdiction onboarding schedules — are provided to verified institutional counterparties under NDA per the terms set forth in #terms and #nda. SPORTINDEX is not registered as an investment adviser, broker-dealer, or financial product issuer in any jurisdiction unless explicitly disclosed under #compliance. Past performance, including hypothetical or backtested performance, is not indicative of future results.

Each constraint is mapped to an existing, named control. The platform is engineered to operate within these boundaries — not to obscure them.
// CONSTRAINT 01 — MODEL DRIFT
α-Excursion Outside Operating Band [NDA]
Heavy-tail exponent excursion would compromise spectrally verified convergence. Control: Continuous drift and calibration monitoring against the documented stability baseline (input drift, prediction calibration, edge decay). The underlying spectral weight audit is re-run at each model update, not continuously. Models breaching the threshold are quarantined before signal release; no override path exists.
