LAB / RELATIONSHIPS / APU020

Follow connections without turning paths into causes.

Relationship Explorer reuses APU004’s authoritative Graph and makes the difference between an assertion, a traversal, and an editorially selected path visible.

Synthetic relationship fixture. Paths expose traversal through existing assertions only; they do not assert causality, importance, or influence.

Task-oriented Lab

Choose the operation, not the page name.

Every Lab tool now uses the same context convention: an optional worked-example key travels in the URL, help is visible in native disclosure controls, and reset returns to the canonical tool route.

Worked-example context is optional and URL-scoped. Enter from the Harbor Light synthetic journey to carry that example between tools, or use any tool without a case key.

ToolAnatomySee how a structure is assembled from explicitly modeled parts.ToolRelationshipsTrace explicit links without turning proximity or chronology into influence.ToolScaleCompare documented measurements while leaving missing dimensions unknown.ToolTime layersRead explicit events and lifecycle states without inventing undocumented in-between states.ToolJourney builderAssemble an evidenced sequence while keeping routing, distance, access, and walkability separate.

How Lab context and reset work

Context is explicit and URL-scoped. The Expedition layer does not create an account profile, hidden personalization state, analytics event, or factual assertion. A ?case=harbor-light key only keeps the same synthetic teaching example visible as you move between tools. Reset by returning to this tool's base route.

TRAVERSAL PATH

A deterministic path is not a new fact.

Fixture Observation Hall→ Part of →Fixture Observation Tower→ Uses material →Fixture Blue Brick

EDITORIAL SELECTION: Chosen to demonstrate a deterministic multi-hop traversal from an interior through its parent structure to explicit material-use evidence. The selection does not create a new relationship.

selectionCreatesAssertion = false

INFLUENCE / INSUFFICIENT EVIDENCE

No influence chain is asserted for this fixture.

insufficient evidence

No explicit influenced_by or influenced assertion exists for this fixture. Chronology, similarity, style, geography, authorship, material, and co-membership do not substitute for influence evidence.

Explicit influence assertions found: 0

Accessible relationship ledger.

Visual paths are always accompanied by structured text. Stable relationship IDs and source IDs remain visible.
