TrackJet Status Ontology

Seven canonical states every carrier wording maps into — the same taxonomy the website timeline, REST/GraphQL API, webhooks and MCP tools emit. Machine-readable: status-ontology.json.

State	Meaning	Example carrier wordings
`pending`	Shipment known, no movement recorded yet.	Label created · Auftragsdaten übermittelt · Pre-advice
`in_transit`	Moving between facilities.	Processed at parcel center · Departed hub · In Zustellbasis angekommen
`out_for_delivery`	On the final delivery vehicle.	Out for delivery · In Zustellung · With delivery courier
`delivered`	Handed over at destination.	Delivered · Zugestellt · Entregado
`exception`	Something blocks normal progress.	Held by customs · Address insufficient · Damaged
`returned`	Going or gone back to sender.	Return to sender · Retoure eingeleitet
`unknown`	Carrier wording could not be classified — shown as-is, never guessed.	(anything unclassifiable)

Design rules

Normalization is additive: the carrier's ORIGINAL wording is always preserved next to the canonical state — we classify, we never rewrite history.
Unclassifiable wordings map to unknown, never to a guess.
exception is a flag, not a terminal state — shipments routinely recover from it.
States are deliberately few: seven states cover cross-carrier comparison; finer distinctions stay in the original wording.

Changelog
