# State Management Standards
|
||
|
|
|
||
|
|
Status: Mandatory
|
||
|
|
Date: 2026-07-03
|
||
|
|
|
||
|
|
## Objectives
|
||
|
|
|
||
|
|
- Keep state predictable, scoped, and replaceable.
|
||
|
|
- Support Website, Builder, and Backoffice without coupling.
|
||
|
|
|
||
|
|
## State Layers
|
||
|
|
|
||
|
|
- Platform State: bootstrap, feature flags, theme, localization, session status.
|
||
|
|
- Domain State: feature-specific bounded context state.
|
||
|
|
- UI State: ephemeral visual state local to component/container.
|
||
|
|
|
||
|
|
## Facade Rules
|
||
|
|
|
||
|
|
- Every domain exposes state through facades.
|
||
|
|
- Facades expose readonly projections/selectors/signals.
|
||
|
|
- Mutations happen through explicit facade commands.
|
||
|
|
|
||
|
|
## Isolation Rules
|
||
|
|
|
||
|
|
- No direct cross-domain state mutation.
|
||
|
|
- No component writes directly into service internals.
|
||
|
|
- Shared state contracts must be explicit and typed.
|
||
|
|
|
||
|
|
## Persistence Rules
|
||
|
|
|
||
|
|
- Persisted state access must be centralized in approved services.
|
||
|
|
- UI components never access localStorage/sessionStorage directly.
|
||
|
|
|
||
|
|
## Feature Flag Interaction
|
||
|
|
|
||
|
|
- State branches for optional capabilities must be capability-driven.
|
||
|
|
- Missing capability paths must return safe defaults.
|
||
|
|
|
||
|
|
## Migration and Compatibility
|
||
|
|
|
||
|
|
- Existing auth/payment behavior remains intact while wrapped by facade boundaries.
|
||
|
|
- Refactoring must preserve observable behavior for critical flows.
