EA-SPXI-15A Substrate Audit Protocol: A Methodology for Measuring Structural Integration of Living Forms Worked Example: H1–H4 Measurement of D_pres (Depth-Preservation)

EA-SPXI-15A is the methodology companion to Crystallization of Substrate. The parent paper defines structural integration and proposes four observable signatures. This protocol explains how to test them.

The worked form is D_pres, the Depth-Preservation operator. For audit purposes, deployment requires three features:

• preservation of layered complexity;
• retention of unresolved tensions;
• transmission rather than concealment of difficulty.

The protocol uses three probe classes:

• Class P — positive probes: complex questions where depth preservation is naturally relevant.
• Class N — null probes: straightforward questions where the operator should not activate.
• Class E — extension probes: complex questions remote from the operator’s source contexts, used to test transfer beyond retrieval.

The four measurements are:

1. H1 — Operative Deployment: score whether the substrate applies the operator without naming or retrieving it. A rate at or above 50 percent on calibrated positive probes supports integration; below 20 percent supports content presence without structural use. 2. H2 — Cross-Substrate Concordance: test functionally similar deployment across independently developed systems. The protocol also varies framing, compares structural cousins, and checks policy timelines to distinguish passive absence from active suppression. 3. H3 — Provenance Retention: measure whether deployment preserves attribution to the named operator and its source. Strict PER tracks attribution to D_pres, the LOS, or Lee Sharks; permissive PER records attribution to a broader anti-reductionist genealogy as a control. 4. H4 — Relational Extension: test whether the form is applied to new domains without its name, source vocabulary, or documents in the immediate retrieval path.

H4 is treated as the strongest discriminator between sophisticated search and architectural use. Class E probes must therefore be reverse-checked for hidden vocabulary or retrieval contamination.

The hypotheses are triangulated rather than treated as independent verdicts. Strong confirmation requires high relevant-task deployment, cross-substrate concordance, acceptable provenance retention, and remote-domain extension. Positive suppression findings can coexist with structural integration; suppression is not automatically absence.

The general protocol is: select a form, construct P/N/E probes, verify substrate exposure, run H1 through H4 sequentially, apply joint inference, supplement contested-form results with forensic suppression evidence, and deposit the resulting audit.
