# G31 Source dependency and change impact graph

## Question

Which lessons, code, tests, and pages must be reviewed when guidance changes?

## Nodes

Source section; Claim; Lesson; Template; Code artifact; Test; Public page

## Relationship sketch

* artifact → depends on claim
* claim → source section
* change → affected artifact

## Evidence inputs

Explicit dependency mappings, source review events, version hashes, actual artifact identifiers.

## Implementation

Track direct dependencies rather than merely storing a bibliography. A source change generates a scoped review queue; it must not silently rewrite production code or mark dependent claims false.

## Acceptance checks

* A simulated source change identifies known dependents
* Unknown impact is reported
* Human review controls promotion of changed requirements

## Do not infer

A changed webpage hash does not prove that the relevant technical requirement changed.

## Publication boundary

Private maintenance graph; public changelog may summarize real updates.

## Source basis

[S14](https://library.feedthejoe.com/graph-systems/primary-source-register/#S14), [S16](https://library.feedthejoe.com/graph-systems/primary-source-register/#S16). See Research/sources.json. Sources support the primitives or named technology. The organization, labels, actions, and acceptance contracts in this catalog are this library's design, not claimed provider requirements.
