Point

Supersession must close lifecycle

A superseded Point remains understandable only when an active replacement names it through an acyclic canonical relation.

Posture
asserted
Lifecycle
active

Changing a Point to superseded is not enough. Another Point’s anchor must declare the incoming supersedes relation, the target must have the matching lifecycle, and the replacement graph must remain acyclic. This gives a reader a deterministic path from obsolete direction to current direction.

History remains only when the replacement explains a current consequence. A relation is not permission to delete source evidence or rewrite the prior Point as though it had always expressed the new model. Withdrawn and historical Points serve different purposes and must not be used to bypass replacement integrity.

Lifecycle and reversibilityAn incoming supersedes edge from an active replacement makes historical state reversible and understandable.

Reading this Atlas

Atlas connects project documents to the claims, decisions, and perspectives they inform. It helps readers find relevant material and understand why it matters.

  1. Start with a Map, then narrow the view through its Areas.
  2. Search for a phrase, title, or Point identity. Filter results by type.
  3. Open a Point for its explanations, related Points, and sources. Follow source links for the underlying material.

Quick reference

Map
A durable project perspective organized around one central question.
Area
A concern within a Map. Areas can overlap; memberships explain why a Point belongs.
Point
One claim, decision, constraint, question, or other coherent item with its own identity.
Context
An explanation of how the same Point matters in another Map.
Relation
A directed link between Points with an explanation, such as support, dependency, or replacement.
Resource
An addressable document or other material.
Content
The primary material for an Atlas item.
Reference
Material linked as evidence, background, implementation, history, or an example.

Missing links do not mean that no relationship exists.

Read the state

Posture describes the author's stance: asserted means presented as applicable or believed; open, unresolved; proposed, a candidate; intended, a desired or selected future state.

Lifecycle describes standing: active means current context; historical, retained prior context; superseded, replaced by another Point; withdrawn, retracted.

Asserted does not mean verified. Intended does not mean implemented. Source links provide material to assess these claims.
