1 · Overlay Identity#

1.1 Purpose#

The Substrate Overlay evaluates the foundational capacity layer beneath any Triadic regime. Every regime — no matter how coherent and structurally sound — rests on a substrate: the underlying medium through which energy, information, or material flows. The Substrate Overlay asks "can the ground hold the weight?" It measures substrate capacity, saturation, porosity, and the degree to which the current regime is approaching the limits of what its substrate can sustain. When substrate capacity is exceeded, regimes collapse from below — not from structural fault or drift, but from the ground up.

1.2 Position in S3 Spine#

The Substrate Overlay is the fourth overlay in the canonical S3 Spine sequence. It requires Structural, Drift, and Coherence overlay outputs before it initializes. Substrate readings inform the Dimensional Overlay (which maps substrate capacity across its dimensional axes) and the Domain Overlay (which applies substrate analysis to domain-specific resource pools).

1.3 Canonical Role#

• Capacity assessor: scores the load-bearing capacity of the substrate beneath the active regime.
• Saturation detector: identifies when substrate is approaching maximum absorption, flow, or load limits.
• Depletion forecaster: projects substrate exhaustion timelines based on current drift and coherence rates.
• Domain-resource bridge: passes substrate readings to domain-specific resource models (Enterprise, qCompute, Radiology, etc.).

4.1 Detection Pipeline#

[Structural Frame + Drift Report + Coherence Report]
    → Stability Basin Cartographer     (basin capacity + saturation scoring)
    → Crystal Mycelial Engine          (distributed flow network analysis)
    → Structural Faultline Detector    (substrate-level fault identification)
    → Temporal Regime Sequencer        (depletion timeline projection)
    → Triadic Regime Synthesizer       (substrate score embedded as resource constraint)
    → [Substrate Report → Dimensional Overlay + Domain Overlay]

4.2 Signal Flow#

Phase 1 — Basin Mapping: The Stability Basin Cartographer maps all stability basins present in the substrate layer. For each basin, it computes:

• Capacity (C): Total load the basin can absorb without regime shift
• Current Load (L): Observed load from Structural + Drift inputs
• Saturation Index (SI): L/C — the proportion of capacity in use
• Depletion Rate (DR): Rate at which capacity is being consumed

Phase 2 — Network Flow Analysis: The Crystal Mycelial Engine models the substrate as a distributed network — channels, nodes, and junctions through which resources flow. It identifies bottleneck nodes (high-centrality, high-congestion), isolated channels (substrate segments cut off from the main flow), and flow inversion zones (where resources move against the primary gradient — a precursor to systemic substrate failure).

Phase 3 — Substrate Faultline Detection: The Structural Faultline Detector is re-applied at the substrate level. Structural faultlines that extend below the regime layer into the substrate are flagged as deep faults — the most critical class, as they indicate the substrate itself is fractured, not merely the overlying regime.

Phase 4 — Depletion Projection: The Temporal Regime Sequencer projects forward: given current SI and DR, when will each basin reach saturation? A Substrate Runway is computed for each domain-specific resource pool (Enterprise, qCompute, Radiology, Fiscal) and published to the Spine bus.
