Task ENG.0 Implementation Report - 2026-07-07

Scope

• start and complete the documentation-only Engineering Governance phase
• review business, architecture, UI, standards, security, and current implementation patterns already frozen by BU-R and AR work
• produce the official engineering governance baseline for future implementation tasks

What Was Produced

• official engineering governance baseline:

Key Decisions Captured

1. ENG.0 freezes review-first and reuse-first implementation as mandatory, not optional advice.
2. Feature ownership, service boundaries, Route Handler patterns, and projection rules now follow one documented model aligned with current repo structure.
3. Business logic remains service-owned; projections remain read-only; route handlers remain thin.
4. Security enforcement is frozen around resolved CRM access, server-side scope enforcement, and pricing visibility checks.
5. UI implementation is frozen to existing dashboard shell, PageContainer, shadcn/ui reuse, and no-code-before-design for major new workspace surfaces.
6. Database, testing, delivery, AI implementation, and code review expectations are now documented in one standards file future tasks can cite directly.
7. Preserve -> Extend -> Controlled Refactor -> Replace is frozen as the engineering decision matrix for change strategy.

Verification

• Documentation-only change.
• No schema, migration, API, service, UI, permission, or runtime business-logic files changed production behavior.
• No build or test command was required for this phase.

Outcome

ENG.0 now gives ALLA OS an explicit Engineering Constitution aligned with:

• Business Constitution (BU-R.0, BU-R.0.1, BU-R.1)
• Architecture Constitution (AR.1, AR.2)
• Workspace UI Constitution
• current foundations and production code patterns already present in the repository
