Source preserved
Original evidence remains intact.
KanGate retains project-native identifiers, document provenance, revisions, and custody events rather than replacing them with an unsupported summary.
Material traceability
Trace source to field. Then reverse the question.
A heat number alone is not traceability. KanGate preserves specification, procurement, receipt, MTR, heat, cut piece, custody, issue, installed location, joint, package, and release consequence.

Forward genealogy
Start with the accepted source and prove every downstream use.
KanGate follows the material from specification and MTR through receipt, heat, component, cut piece, custody, issue, installed location, weld or joint, package, and controlled output.

Chain of custody
Every handoff must preserve the same material truth.
A complete MTR does not prove that accepted material became installed material. Custody, subdivision, field issue, and installation remain separate facts until each is validated and connected.

Break visible05
Package consequenceThe affected package remains held until identity is restored.
BlockedBreak exposed
Uncertain identity cannot quietly become release-ready.
Where the chain breaks, every dependent joint, package, manifest, and authority-review state inherits the visible consequence.
Controlled material proof
Begin with one material chain that is difficult to defend today.
Use real project evidence to test identity resolution, custody, installed-location proof, blocker behavior, and package consequence.
