ADR-010: Frontend Context Boundaries (App State Only)

Status: Accepted
Date: 2026-03-09
Deciders: CepatEdge maintainers

Context

Context growth risked becoming a mixed store for app state and server datasets.

Decision

Keep context for app-level shared state only:

• auth
• system metadata catalog
• notifications global state
• ui global state
• theme

Use query hooks for server datasets.

Consequences

Positive

• Cleaner ownership boundaries
• Fewer stale-state bugs
• Easier onboarding and testing

Negative

• Requires discipline to avoid introducing list/detail data into context
