# Task AR.1 Implementation Report - 2026-07-07

## Scope

- start and complete AR.1 as a documentation-only architecture transition phase
- review the frozen BU-R business baseline, current production CRM implementation, reusable foundations, ADRs, security boundaries, and transition seams
- record the official transition architecture baseline for later AR.2 epics and technical design

## What Was Produced

- created the main AR.1 transition architecture artifact:
  [task-ar.1-architecture-transition-plan-2026-07-07.md](/C:/Users/mtpphtaps/Documents/gitea/alla-allaos-fullstack/docs/implementation/task-ar.1-architecture-transition-plan-2026-07-07.md)

## Key Decisions Captured

1. Current production CRM domains remain the write owners and must be preserved.
2. New capability should arrive as:
   - shared `Activity` domain
   - generated `Timeline` projection
   - generated `Calendar` projection
   - role-oriented CRM workspaces
3. Existing admin `/dashboard/workspaces` routes are preserved for organization administration and must not be silently reused for business-role workspace navigation.
4. `Approval` stays the document workflow owner, `Opportunity` stays the business outcome owner, and `Quotation` stays the document lifecycle owner.
5. Notification expansion, My Day, Manager Workspace, and Executive Workspace must build on event/projection layers rather than creating duplicate lifecycle stores.

## Verification

- Documentation-only change.
- No schema, API, UI, service, permission, or business-logic runtime change was made.
- No build or test command was required for this phase.

## Outcome

AR.1 is now recorded as the architecture transition baseline that future epics can reference for preserve/extend/refactor decisions, event design, projection strategy, workspace routing, dependency analysis, and implementation ordering.
