STD-ARC-006: The Construction Hierarchy (Building Order) Planning Pattern

Status: ACTIVE Category: Architecture / Planning Date: 2026-02-10

1. Governance & Philosophy

All roadmap and feature planning on the Singular Dream platform must follow the "Building Order" principle. This ensures that the high-value, cinematic end-states (The Penthouse) are physically and logically supported by weight-bearing foundational layers.

[!IMPORTANT] The Golden Rule: No L4 (Innovation) feature may be implemented until its L1 (Foundation) and L2 (Structural) prerequisites are verified in the codebase.

2. The Four Tiers of Construction

🧱 Level 1: Foundation (The Ground Floor)

  • Definition: Bare-metal infrastructure, base data schemas, identity resolvers, and system triggers.
  • Success Criteria: The "Weight-Bearing Slab" is poured. Data can be stored and retrieved, and core security/identity is established.

🏛️ Level 2: Structural (The Frame)

  • Definition: Relational logic, cross-domain signal bridges, automated reflexes, and background services.
  • Success Criteria: The "Connective Tissue" is active. Module A can talk to Module B via the Signal Bus.

🏢 Level 3: Functional (Tenant Services)

  • Definition: High-utility UI workbenches, dashboards, formalized reporting, and user-facing workflows.
  • Success Criteria: The "Shops" are open. Users can perform their daily tasks through standardized interfaces.

🌟 Level 4: Innovation (The Penthouse)

  • Definition: Agentic AI capabilities, autonomous self-healing, predictive telemetry, and high-fidelity "wow" factor.
  • Success Criteria: The "Skyline" is complete. The system acts as a proactive agent rather than a reactive tool.

3. Planning Protocol

When a new "Strategic Pillar" is introduced:

  1. Deconstruction: Disassemble the pillar into its component levels (L1 through L4).
  2. Mapping: Update the STRATEGIC_FORWARD_PLAN.md within these tiers.
  3. Sequencing: Execute development strictly from Level 1 upwards.
  4. Verification: Each level must pass a "Convergence Point" before the next level begins.

4. Enforcement

Roadmap audits will highlight any "Hanging Penthouses"—features planned for L4 without corresponding L1-L2 support. These will be flagged for immediate foundational prioritization.
