# Merged Learning Graph
|
|
|
|
## Purpose
|
|
|
|
The merged learning graph is the first learner-facing composite model built from multiple domain packs.
|
|
|
|
## Features in this revision
|
|
|
|
- namespaced concept keys: `pack-name::concept-id`
|
|
- merged prerequisite DAG
|
|
- stage catalog across packs
|
|
- project catalog across packs
|
|
- optional overrides for previously defined concepts
|
|
|
|
## Override model
|
|
|
|
A pack manifest may include:
|
|
|
|
```yaml
|
|
overrides:
|
|
- foundations-statistics::descriptive-statistics
|
|
```
|
|
|
|
If a pack defines concept `descriptive-statistics` and lists the namespaced target above, it may replace that concept in the merged graph.
|
|
|
|
That is intentionally explicit and conservative.
|
|
|
|
## Future work
|
|
|
|
- merged rubric graph
|
|
- stage dependency inference
|
|
- learner-specific subgraph extraction
|
|
- adaptive sequencing from the merged DAG
