Terms of Intraday Evidence

Canonical language for market drift attestations, provider-drift witnesses, and replay-ready artifacts used in Sovrient's market lanes. This page defines what is measured and what is intentionally out of scope.

This glossary defines measurement semantics and verification boundaries for Sovrient's market lanes. It distinguishes observed state from interpretation and establishes replay conditions for evidentiary publication.

Section I

Industry Standard Terms

Common terms from market microstructure and risk operations, expressed in neutral operational language.

VWAP (Volume-Weighted Average Price) Industry

The volume-weighted average traded price over a defined time window; used as an execution and price-quality benchmark.

Microstructure Noise Industry

Short-interval price and volume variation caused by quote updates, trade sequencing, and venue effects rather than fundamental repricing.

NBBO Industry

The National Best Bid and Offer consolidated from eligible venues. Serves as a reference for top-of-book conditions in U.S. equities.

SIP vs Direct Feed Industry

Two market-data pathways with different characteristics. SIP is consolidated and standardized; direct feeds are venue-native and can differ in timing and field behavior. Differences may arise due to aggregation logic, timestamp granularity, and transport latency. These differences are structural and do not imply data error.

Section II

Sovrient-Originated Terms

Canonical terms for the market-drift lane, designed for auditability and replay rather than narrative interpretation.

Market Drift Attestation Sovrient

A sealed daily artifact for Canonical market lanes that reports measured totals, witness hashes, and anchor references for independent replay.

Boundary: evidentiary state publication only. Not investment advice, not discretionary trade instruction, and not market interpretation.

Canonical 5 (C5) Sovrient

Five-symbol lane used for strict cross-feed drift observation and witness publication in fixed intraday windows.

Inclusion rules are versioned and declared prior to publication.

Canonical 8 (C8) Sovrient

Eight-symbol lane extending the measurement surface while preserving deterministic replay and attestation semantics.

Inclusion rules are versioned and declared prior to publication.

Canonical (Market Lane Context) Sovrient

A deterministic symbol universe and window structure whose inclusion rules, ordering, aggregation semantics, and rounding regime are fixed for replay and audit purposes.

Provider Drift Witness Hybrid

A cross-feed comparison artifact that quantifies window-level and aggregate divergence between declared providers under one metric definition.

Interpretive boundary: reports measured divergence only; does not assign fault or causality. Drift is defined strictly as numeric divergence under identical metric definitions, window constraints, and rounding semantics.

Cross-Feed Delta Sovrient

The signed total difference between two feed totals for the same date, universe, and metric context, computed under identical symbol universe, time window, metric definition, and rounding regime.

Protocol & Verification Terms

Terms that define admissibility: if these checks fail, publication is incomplete.

DT0 (Zero Drift Condition) Protocol

A lane state in which all declared cross-feed totals reconcile under the specified metric, window, and rounding semantics, producing no residual ambiguity at the witness level.

DT0 is required for authoritative publication.

Network Determinism Protocol

A state in which independent verifiers converge on one published value under shared consensus rules.

Scope boundary: proves inter-party agreement. It does not, by itself, prove that only one computational path exists.

Computational Determinism Protocol

For declared canonical inputs, configuration, ordering, window constraints, and rounding semantics, computation has exactly one valid output and one canonical hash.

Sovrient posture: corroboration constrains input state; computational determinism constrains output state.

Deterministic Replay Protocol

Recomputing with declared inputs and configuration must produce the same output state and witness hash.

Replay environment is bounded by declared inputs, configuration, and ordering semantics; hardware and OS variance outside declared scope does not alter canonical hash output. Replay must produce identical canonical hash output.

Capture-Before-Interpretation Boundary Protocol

A publication rule where raw source payloads and capture-window metadata are hash-sealed before downstream transforms, scoring, or narrative interpretation.

Later source revisions are published as new attestations. The first-capture record remains immutable and replayable.

Input Witness Protocol

A hash-stamped record of canonical input files used for a specific run date.

Witness ordering is canonicalized prior to hashing to prevent filesystem-order variance.

Sealed Innovation Hash Protocol

The immutable digest of the sealed innovation artifact associated with a lane/day package, representing the artifact identity for that date.

On-Chain Mint Receipt Protocol

Transaction-level confirmation linking the attestation identity to a public chain record (currently Sepolia in pre-mainnet mode).

Chain anchoring is evidentiary and timestamp-oriented; it does not alter off-chain computation semantics. Anchoring does not substitute for deterministic replay; it attests to timestamp and existence only.

Fail-Closed Lane Behavior Protocol

If required checks fail, no authoritative state is published until rerun and verified.

Section IV

Cross-Domain Geophysical Terms

Public-safe terms for reusing sealed geophysical evidence across domains (for example, settlement verification and exploration prioritization) without over-claiming certification or legal authority.

Exploration Targeting Industry

The process of ranking geographic zones for follow-up geoscience work (survey, sampling, drilling) based on observed signals and geological context.

This is prioritization, not reserve certification.

Geodetic Deformation Signal Industry

Measured ground displacement from geodetic sources such as GNSS and InSAR, used to characterize crustal movement and deformation patterns.

Deformation signals are physical observations and should be interpreted with domain-specific geological methods.

Structural Permeability Proxy Industry

An indirect indicator of fracture and flow pathways inferred from stress/deformation behavior and related observations.

Proxy signals support hypothesis testing; they do not, by themselves, establish commercial mineralization.

Cross-Domain Attestation Reuse Sovrient

Use of one sealed, replayable evidence artifact in more than one decision context while preserving the same canonical inputs, hashes, and verification chain.

Same evidence root; domain-specific interpretation remains external.

Exploration Prioritization Signal Sovrient

A ranked, evidence-linked signal derived from sealed geophysical measurements to help decide where to investigate next.

Scope boundary: prioritization aid only; not resource classification, valuation, or permit recommendation.

Domain-Scoped Interpretation Boundary Protocol

A governance rule that separates deterministic measurement output from downstream interpretation authority.

Sovrient publishes verified measurement state; sector experts, counterparties, and counsel retain interpretation and decision authority.
