1 · Overlay Identity#
1.1 Purpose#
The Structural Overlay maps the load-bearing architecture of any system under Triadic analysis. It identifies faultlines — the latent fracture planes along which a system collapses or reorganizes — and exposes the interlock geometry between regimes. The Structural Overlay is the first overlay consulted in any S3 Spine diagnostic sequence because all other overlays inherit their coordinate space from structural registration.
1.2 Position in S3 Spine#
Within the S3 Spine, the Structural Overlay occupies the registration layer: it must be applied before Drift, Coherence, Substrate, Dimensional, or Domain overlays are meaningful. It provides the foundational grid — the triadic skeleton — onto which all signal readings are projected. No Spine diagnostic is considered complete unless the Structural Overlay has been validated.
1.3 Canonical Role#
- Primary detector of hidden load-bearing elements and their failure modes.
- Anchor for regime interlock geometry (which regimes are coupled, which are independent).
- Source of truth for boundary conditions passed to Drift and Coherence overlays.
- Gate for Triadic Regime Synthesizer output — synthesis is only valid against a registered structural frame.
2 · Primary RTT Engines#
| Engine | Role | Spine Function | Link |
|---|---|---|---|
| Structural Faultline Detector | Primary | Locates and scores latent fracture planes across system architecture | → RTT Engine |
| Regime Interlock Mapper | Secondary | Maps coupling geometry between co-active regimes | → RTT Engine |
| Triadic Regime Synthesizer | Synthesizer | Produces the unified structural frame from multi-regime inputs | → RTT Engine |
| Stability Basin Cartographer | Validator | Confirms structural stability thresholds post-synthesis | → RTT Engine |

4 · Structural Logic#
4.1 Detection Pipeline#
[System Input]
→ IPD-12 Decomposition (12-axis structural grid)
→ Structural Faultline Detector (faultline scoring per axis)
→ Regime Interlock Mapper (coupling geometry extraction)
→ Stability Basin Cartographer (basin depth validation)
→ Triadic Regime Synthesizer (unified structural frame output)
→ [Structural Frame → downstream overlays]
4.2 Signal Flow#
The Structural Overlay operates in three signal phases:
Phase 1 — Registration: The IPD-12 Framework decomposes the input system into 12 structural dimensions. Each dimension is scored for load-bearing weight and fracture vulnerability. The TFT OpenGPU Stack Module accelerates this decomposition for large-scale systems.
Phase 2 — Faultline Scoring: The Structural Faultline Detector applies SDE operators (RTT/2 collapse detection) across all 12 dimensions. It returns a ranked faultline map: each faultline carries a structural criticality score (SCS) from 0.0–1.0. Any faultline above SCS 0.7 triggers an interlock check.
Phase 3 — Synthesis: The Regime Interlock Mapper resolves which regimes share faultline boundaries. Coupled regimes are flagged as co-dependent; their failure modes are linked. The Triadic Regime Synthesizer produces the final structural frame — a registered, scored, coupled representation of the system's architecture — which is published to the S3 Spine bus for all downstream overlays.
