The Framework

The Constraint Chain

Every Mexel analysis follows the same discipline: start from the headline everyone sees, find the physical constraint almost no one sees, and trace the transmission path between them — ending in an explicit trigger and an explicit invalidation condition.

01
Headline — the visible event: an export control, a policy shift, a demand surge, a supply disruption.
02
Hidden bottleneck — the underappreciated physical, chemical, process, or equipment constraint the event activates. This is where Mexel's canonical card library does its work.
03
Transmission chain — the step-by-step path from chokepoint through the supply chain to market implication, stated explicitly so each link can be checked.
04
Market implication — sector, commodity, and equity-level exposure, with the logic stated rather than asserted.
05
Decision signal — a time-bounded trigger to watch, and the condition that would prove the analysis wrong.
The Knowledge Layer

Canonical bottleneck cards

Mexel maintains a curated library of bottleneck cards — structured research notes on specific process inputs, equipment classes, and manufacturing constraints. Each card records the same fields, so every analysis is built on comparable, auditable scaffolding.

What each card records
The hidden constraint · exact process role · failure mode · lead-time risk · supply concentration · chokepoint and sanctions exposure · downstream sectors · triggers to watch · easing/invalidation conditions · public-equity relevance.
How cards are used
When you run a Scenario, Rapid Response Memo, or signal analysis, relevant cards are matched and injected as analytical context. Outputs cite which cards informed them — analysis is grounded in the library, not improvised.
Confidence marking
Every card carries an explicit confidence level, and every generated output states its confidence with a reason. Where a figure is indicative rather than verified, it is labelled as such.
Data Sources

Official sources, visible provenance

Mexel's live signal feed and market data come from official and institutional sources. Every data point on the platform carries its own as-of date and source attribution.

Layer Sources Cadence
Signal feedEIA · USGS · IEA · US DOE · Federal Register · EUR-Lex · GDELTContinuous, scheduled refresh
Energy pricesEIA official series (Brent, WTI, Henry Hub), via Federal Reserve (FRED)Daily
Metals & bulk pricesIMF Primary Commodity Prices (copper, aluminium, nickel, zinc, tin, uranium, iron ore, coal), via FREDMonthly
Knowledge cardsCurated from public filings, agency reports, trade publications, and technical literature; source references recorded per cardReviewed continuously
Minor and specialty materials without a free official price series (e.g. gallium, germanium, antimony) are marked indicative wherever shown, never presented as live quotes.
AI Disclosure

AI-accelerated. Human-judged.

Mexel uses large language models to synthesise signals against its structured knowledge layer and to draft analytical outputs. We say this plainly because it is true, and because the alternative — pretending a research team of forty produced it — is the kind of dishonesty this platform exists to counter.

What the AI works from is proprietary: the canonical card library, the constraint chain framework, the source pipeline, and the scoring discipline. What governs it is editorial: outputs must state confidence with a reason, must include invalidation conditions, and must not fabricate figures — where a number cannot be verified from a recorded source, it is labelled indicative or omitted.

Structured intelligence outputs are decision-support material, not a substitute for professional advice.

Limits

What Mexel does not claim

Mexel does not predict prices, does not provide investment, legal, or financial advice, and does not claim certainty. It maps structural constraints and states, explicitly, what would prove each analysis wrong. Scenario probabilities are structured judgments, not measured frequencies. Where our sources are periodic rather than real-time, the timestamps say so.
