Collaborator Handbook

Pilot study expectations

How partners work with Rex Autistikon Research Foundation without circular definition of the independent variable.

Current status

  • Research architecture established — research question, layered method (measurement → representation → transmission → physiological test), zone taxonomy, falsification criteria (F1–F3), and collaboration governance.
  • Measurement protocols under development — zone-specific mechanical acquisition, calibration/QC, and test–retest plans are being defined; they are not yet locked as validated standard operating procedures.
  • Computational transmission layer currently illustrative — interactive model and Phase 1 intake parameters (including restriction-like / didactic controls and observational MPA-style scores) explore predicted transmission quantities. They are not empirical tissue measurements.
  • Empirical validation pending — reliability of candidate mechanical measures, coherence of any latent “restriction” construct, and preregistered prediction of independent physiological outcomes have not yet been demonstrated.

1. Purpose of collaboration

Partners collect zone-appropriate mechanical measurements (and, where approved, physiological outcomes). RAL provides governed intake, versioned computation of transmission predictions, and de-identified aggregation tools. Partners retain responsibility for ethics, local protocol validity, and human-subjects compliance.

2. Independent variable policy

Do not treat “restriction r” as a field you simply “know.” Primary experimental emphasis: measured mechanical quantities → documented representation → optional model predictions → independent physiological tests.

“Mechanical restriction” is a hypothesis-level latent construct. The computational model must never define restriction retrospectively. No post-hoc composite index adjustment based on outcome fit is permitted.

3. Three layers

  1. Measurement — instrumented observables, zone-specific.
  2. Mechanical representation — derived parameters with units and transforms specified in advance.
  3. Computational transmission — predicted metrics from a stated representation; version-stamped.

4. Zone dossiers (required)

For each of the eight zones, document:

  1. Anatomical target
  2. Measurable mechanical properties (candidates)
  3. Acquisition method / instrument class
  4. Calibration and quality-control procedures
  5. Expected measurement range
  6. Test–retest requirements
  7. Permitted transforms into the common computational representation
  8. Measurements unavailable or inappropriate for that zone

The common element is the analytical framework, not a single physical technique for all zones.

5. MPA and observational scores

Record if useful for secondary, preregistered analyses. Do not use as the primary computational stand-in for mechanical state unless validation criteria agreed in advance are met.

6. Composite restriction index (if ever used)

Must be locked before outcome analysis:

  • Components, units, normalization
  • Weighting / dimensional reduction
  • Missing-data rules
  • Reliability thresholds
  • Zone-specific procedures
  • Mapping to transmission-model inputs

7. Falsification

The restriction construct is weakened or rejected for a zone/protocol if:

  • measures are unreliable under pre-set criteria;
  • candidate measures do not cohere where a shared construct is claimed; or
  • mechanical state fails preregistered physiological prediction.

Do not “fix” failures by adjusting the model or index after seeing outcomes.

8. Phase 1 software honesty

Current intake may still expose illustrative fields (including restriction-like and MPA fields) so teams can exercise the pipeline. Label methods sections and exports accordingly: illustrative / Phase-1 computational, pending measurement-layer protocols in the zone dossiers. Stored runs include model_version.
