## Summary

When the curated architecture map is the source, ADRs, blueprints, and diagram images become outputs rather than hand-built documents. The map holds entities, relationships, and How/Why evidence; generation selects a slice, renders it, and cites it. This extends "how to generate architecture docs from living context" (E1) and explains why solution architects have a reason to keep the map healthy. Diagrams are generated from curated context — DecisionPen is not a drawing canvas.

## What changes when artefacts are outputs of the map?

- Authority moves upstream: corrections land once in the curated model.
- Drafting gets cheaper: architects spend time on trade-offs, not re-listing neighbours.
- Provenance survives: claims trace to entities and evidence.

## How do you generate an ADR from the map?

1. Scope the decision (entities in play).
2. Pull the slice: neighbours, integrations, owners, prior decisions, evidence.
3. Draft the record: context and consequences from the slice; options and decision remain the architect's judgement.
4. Review and ratify; write the accepted decision back to the map.

## What is a blueprint generated from living context?

A solution or target-state view for a bounded change: the current-state slice from accepted entities, overlaid with the proposed delta (flagged as proposals until curated) plus constraints and rationale pulled with evidence.

## How are diagram images generated without a canvas?

A diagram is a visual projection of a graph slice. Given structured entities and relationships, an image can be rendered — landscape view, integration map, capability-to-application overview. When the model changes, the diagram can be regenerated. For bespoke layout, use the generated image as the factual baseline and finish it in a drawing tool.

## Why do solution architects keep the map healthy? (the flywheel)

If an HLD requires rediscovering the landscape, the map is someone else's chore. When the same map drafts the ADR, blueprint, and diagram, fixing a stale relationship becomes the fastest route to a deliverable. Accepted artefacts and decisions flow back, so the next architect starts from a better map: use creates curation, curation improves the next use.

## What makes a generated artefact trustworthy?

Curated inputs; citations; human sign-off; reproducibility from map state.

## How DecisionPen solves this

Architecture Decision Workspace: ADR drafts from the affected slice, blueprints overlaying change on curated current state, generated diagram images from the map, citations and curation; Enterprise Ask reads the same map. Trial: https://decisionpen.com/trial

## When is DecisionPen the wrong tool?

Freeform drawing canvas, pixel-perfect presentation diagrams, BPMN modelling, general writing Copilot, or when nobody will curate the underlying map.

## FAQ

**Can you generate ADRs from enterprise architecture context?**  
Yes — context and consequences can be drafted from the affected slice of the curated map; the decision itself stays with the architect and the accepted outcome is written back.

**How is this different from generating architecture docs from living context?**  
It builds on that approach and focuses on decision records, blueprints with a proposed delta, and generated diagram images — plus the incentive loop for solution architects.

**Does DecisionPen replace Visio or Lucidchart?**  
No. Diagrams are generated from curated context; DecisionPen is not a drawing canvas. Use drawing tools for bespoke layout.

**What is a blueprint in this context?**  
A bounded target-state or solution view overlaying a proposed change on the curated current state, with constraints and evidence.

**Why does this create an incentive for solution architects?**  
Correcting the map is the fastest way to produce an accurate artefact, and accepted artefacts improve the map for the next change.

**When is DecisionPen the wrong tool?**  
When the job is freeform drawing, BPMN, or generic writing assistance, or the map will not be curated.
