KG subscriptions

A substrate is an external Knowledge Graph: a repository whose root declaration meets bootstrap’s schema requirements and declares at least one harness. An instance subscribes to one at a pinned commit, then chooses which of its subgraphs, assets and harnesses to hold. Everything it does not choose stays referenced: known, and not copied. Design: the KG subscriptions proposal (issue #1719).

Known substrates

Derived from the declarations wherever a fact exists: a staged instance’s planned repository, and an associated harness’s site. Only what no declaration can say is hand-entered, in knownSubstrates.

substrate	repository	status	tools repository	source	note
iHRIS Knowledge Base ihris	litlfred/ihris	📦 exists	—	associated harness	—
WHO IRIS who-iris	litlfred/who-iris	📦 exists	—	hand-entered	Repository created 2026-09-30 and empty; the staged instance sits in the checkout under the same name. Seeding is held (kg-separation stage 10) until the owner says so. The WHO voices style guide merges into it as a subgraph.
WHO World Health Data Hub who-world-health-data-hub	—	💡 proposed	—	hand-entered	Proposed by the owner 2026-09-30 as a repository per large KG asset type; no instance or repository yet.

Subscriptions

No instance subscribes to a substrate yet. The first planned subscription is litlfred/ihris, which is already associated (epic bean fnx4).
