INV-ARC-010: Explicit Context Switching

Reference Number	Version	Effective Date	Supersedes	Authority Level
INV-ARC-010	1.1	2026-10-14	1.0	Constitutional

I. Purpose

Ensure context changes are explicit and observable.

II. Scope

Applies to all request or actor context switching.

III. Authority Level

Constitutional within INV-ARC. Derived from INV-CORE-000 Section III.4, Principal and Actor Authority, and governed within the hierarchy described by INV-CORE-001.

IV. Dependencies

• docs/INVARIANT/CORE/INV-CORE-000_CORE_INVARIANTS.md
• docs/INVARIANT/CORE/INV-CORE-001_CAPABILITY_BASED_ARCHITECTURE_AND_AUTHORITY_MODEL.md
• INV-ARC-001_SCOPED_REQUEST_CONTEXT.md

V. Core Rule

All context changes MUST be explicit.

Implicit reuse of prior request state is forbidden.

VI. Rebuild Intent

This rule exists to prevent convenience reuse of prior class, actor, or session state from becoming hidden authority.

VII. Downstream Consequence

FEAT flows must represent context changes explicitly, and DOM must not assume that a previous request established valid scope for the current one.

VIII. Amendment

Revisions must preserve explicit context switching.
