Five operational layers — Signal, Encoding, Vector, ClEx, Intervention. Each layer is deterministic, traceable, and independently testable. This document specifies what each layer ingests, computes, and emits, and how they compose into the Cultural Experience scalar.

A specification of the five-layer ClEx pipeline — what enters, what is computed, and what is emitted at each stage. Validation and feedback close the loop.

§00 — Pipeline overview
Signal → Encoding → Vector → ClEx → Intervention. Each layer has a defined input, a deterministic operation, and a typed output that the next layer consumes. Calibrated feedback from accepted interventions returns to the encoding model.
Same inputs yield the same outputs. Versioned weights and seeded computations.
Each ClEx scalar is reconstructible from the signal record. Audit-grade provenance.
Each layer has a contract. Layers can be substituted, profiled, and validated independently.

§01 — Signal ingestion
Raw observations from text, voice, behavioural traces, and structural metadata are collected continuously per session. Sources are de-duplicated, time-stamped, and normalised before encoding.
Sources contribute proportional to observed information density per dimension, not to raw volume.
Quasi-duplicate detection on n-grams + cosine similarity removes burst-driven over-representation.
All ingestion respects per-tenant policy. PII is hashed at the boundary before storage.

§02 — Encoding layer
Each signal is encoded into a continuous feature per cultural dimension via a learned projection. Encodings are smooth, sigmoid-bounded, and dimension-aligned.
W_feat is the learned weight tensor mapping context vectors CV onto each cultural dimension.
Sigmoid activation bounds each feature to (0,1) and stabilises downstream aggregation.
Weights are versioned. Recalibration is gated by the validation framework to prevent drift.

§03 — Vectorization
Encoded features are aggregated into the experience vector E and compared against the user prior U. The signed difference Δ identifies dimensions of cultural friction or alignment.
U is constructed from the rolling longitudinal model of the participant cohort or the individual, depending on resolution.
Positive Δᵢ indicates expectation exceeds experience on dimension i; negative Δᵢ indicates over-delivery.
A bootstrap band is reported alongside Δ. Low-confidence dimensions are flagged downstream.

§04 — ClEx computation
Weighted aggregation modulated by context factor (CF) and meaning resonance (MR) yields the ClEx scalar — a single bounded number with a confidence band.
CF accounts for the situational moderators that change how a dimension contributes to perceived experience.
MR captures alignment between expressed cultural intent and lived signal at the cohort level.
The contribution map is preserved end-to-end so any ClEx value is reconstructible at audit time.

§05 — Intervention logic
The recommendation engine emits ΔClEx forecasts for each candidate action. Accepted actions are observed, measured against forecast, and fed back into the encoding model for calibration.
Argmax over expected ΔClEx, subject to operational constraints and policy filters at the tenant level.
Realised effect is measured via difference-in-differences against a matched control window.
Realised − forecast residuals feed the calibration loop. Drift triggers gated recalibration.
Datafolk · ClEx Methodology — System Breakdown
§06 — Validation framework
Every accepted intervention is treated as a quasi-experiment. Realised effects are measured against forecasts using difference-in-differences, and residuals feed the closed-loop calibration of the encoding model.
Treated and control units are matched on pre-period ClEx trajectory and structural covariates. Post-period divergence isolates the action effect from the underlying trend.
Each recommendation carries a forecast ΔClEx with uncertainty. Realised − forecast residuals are persisted with the action record and used as the supervision signal for calibration.
Residuals are aggregated per dimension and per context. When the gated drift criterion is met, the encoding weights W_feat are updated under a constrained step that preserves dimensional interpretation.
Cohort balance is enforced before estimation. Sensitive subgroups are reported with their own residual bands, never collapsed into the headline metric.
