INV-ARC-014: No Label Based Logic

Reference Number	Version	Effective Date	Supersedes	Authority Level
INV-ARC-014	1.1	2026-10-14	1.0	Constitutional

I. Purpose

Prevent labels from becoming identity or scope authority.

II. Scope

Applies to all runtime execution paths.

III. Authority Level

Constitutional within INV-ARC. Derived from INV-CORE-000 Section III.1, `class_id` Centric Isolation, and Section III.6, Class Identity and Membership Model (Existence-Based), 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-009_DOMAIN_AUTHORITY_FOR_STATE.md

V. Core Rule

Execution MUST NOT depend on:

• labels
• sections
• periods

Only canonical identifiers such as class_id may be used for runtime authority. join_code may only be used as a boundary-ingress alias that resolves to class_id before execution-time logic begins.

VI. Rebuild Intent

This rule exists to prevent labels, sections, periods, and similar metadata from re-entering the rebuilt app as identity, grouping, or authority shortcuts.

VII. Downstream Consequence

DOM and FEAT must treat labels as metadata only, never as canonical routing, ownership, lifecycle, or execution keys.

VIII. Amendment

Revisions must preserve canonical-identifier-only execution.
