The full-stack position for AI-era lineage infrastructure.

A stack framing for lineage on .ai — the canonical coordinate for platforms building comprehensive provenance infrastructure from substrate to application layer.

Matched pair · sold together

Held and transacted as one position. A matched .ai + .com pair forecloses its own most common confusable — one coordinate, not two names.

Coordinated sets this position belongs to — the coverage it extends. Counts are the live cluster size in the graph.

Why this is canonical

'Stack' names the complete vertical slice of a technology area — from primitives to applications. Pairing it with 'lineage' on .ai claims the position for platforms that provide not just a lineage feature but a full lineage stack: storage, APIs, integrations, and intelligence, purpose-built for the agentic era.

Where it fits

A few directions this coordinate opens —

Agentic lineage infrastructure
A complete stack for capturing and querying lineage across agent systems — from low-level provenance primitives to high-level governance APIs.
Agentic AI platform vendors, AI infrastructure builders
Data lineage full-stack
A vertically integrated lineage product covering collection, storage, query, and visualization — replacing fragmented point solutions.
Data platform vendors, data governance tooling builders

Illustrative, not exhaustive — held as a transferable canonical position, open to the buyer's own use.
