Méthodologie et règles de sourcing

Principes

Eurotrack separates three kinds of content: events (Developments), measurements (Comparison, EU & partners, energy) and assessments (Situation). An assessment is not a fact; it points to findings and their sources.
Every item rests on a publicly accessible source with a link. The linked source is authoritative, not the summary here.
Research and texts are produced by autonomous AI routines: daily for Developments and Situation, monthly by a script without AI for the measurements. Errors are possible; every correction is welcome.

Seuls les événements disposant d'une URL source réelle et fonctionnelle (site d'information ou communiqué de presse) sont enregistrés ; chaque nouvelle URL est vérifiée automatiquement avant intégration.
La date est celle de la première annonce publique ; les chiffres sont saisis tels quels ou laissés vides ; jamais estimés.
Règle des deux sources : les entrées portant sur plus de 1 000 salariés concernés ou plus d'un milliard d'euros exigent une seconde source indépendante ; à défaut, le chiffre est explicitement signalé comme provenant d'une source unique.
Les rumeurs et les informations exclusives de la presse sont signalées comme telles (« selon … »).
Une même annonce reprise par plusieurs sources donne une seule entrée ; une suite d'événements ne devient une nouvelle entrée que si un élément substantiel a changé.
Les dossiers en cours (offres de rachat, fermetures annoncées, échéances) restent dans le suivi jusqu'à leur dénouement.

Each category is assessed against a fixed catalogue of guiding questions and pre-committed tipping thresholds. Every run researches afresh; every finding needs a source with a link, counter-indicators are mandatory, and every threshold is checked explicitly (not triggered · partial · triggered).
Colour and direction per category rate the change since the last run, not the absolute situation: a grave but unchanged situation reads as “stable”. The sentence under the title states the reason; the bar row shows the direction of recent runs (oldest on the left, faded bars = runs carried over unchanged).
In the navigation of the Situation page, “Δ” marks a category with a substantive change since the last run; the dot next to it shows the most severe status among its thresholds.
“Partial coverage” marks a run that did not reach all guiding questions or primary sources: “no change” then only means “nothing evidenced”. “Lapsed” marks a threshold whose event is more than 30 days old and no longer has continuing effect.
Web search is a sample, not a full picture. Open the primary sources yourself for decisions that matter. An unchanged situation is a valid result.

Each core claim carries an evidence level:

Substantiated: independently corroborated: several independently reporting sources; syndication of one wire item does not count twice
Plausible: a single source, or a party's own account. Claims by a party to a conflict about its adversary are capped here
Disputed: solid sources contradict each other
Unsubstantiated: claim without independent support
Refuted: contradicted by evidence

The EU27, the US and China are only compared using the same source and the same definition. The EU value comes from the source itself; where it has none, it is the population-weighted mean or the sum of the 27 member states; each indicator page names the method.
The spread of the member states is shown next to the EU value, because an average hides large differences.
Every value carries its reference year and retrieval date. Where the latest years differ, this is stated; missing country values are carried forward for a few years at most and named on the page.
There is no overall score and no ranking. Each indicator states its caveats (estimates, method changes, comparability).
The data (World Bank, Our World in Data, Ember, SIPRI and others) is fetched monthly by a script without AI.

Population, economic output, the convergence criteria values and the list of trade agreements notified to the WTO are fetched automatically every month from the World Bank, Eurostat and the WTO.
The negotiation status of the candidate countries and of EU trade agreements is researched, primarily from the Commission, the Council, the Official Journal and the Court of Justice. Every entry names its sources and the date it was last checked; reached milestones are checked promptly, all other entries at least every four weeks.
The reference values of the convergence criteria are approximations. The convergence reports of the ECB and the Commission are authoritative.
