BenchEWS Studio 3.0 ECHO
A public research-to-software archive: every planned module is connected to its scientific basis, epistemic boundaries, implementation status, and later verification evidence.
RESEARCH & ARCHITECTURE PHASE · NOT A RELEASED PRODUCT
01 / Purpose
From research result to auditable software
BenchEWS Studio 3.0 ECHO is the planned next diagnostic architecture of the BenchEWS Research Programme. This page is its canonical public archive. It deliberately distinguishes published theory, specification, prototype, implementation, and release.

Status vocabulary: Research → Specification → Prototype → Implemented → Released. A publication never implies that the corresponding software capability already exists.
02 / ECHO MODULE MAP
Modules with explicit evidence boundaries
SPECIFICATION · PUBLISHED 18 SEP 2026
ECHO — DRIFT
Disturbance–Recovery Inference & Fidelity Test. Metrological gate that checks whether passive structural or spectral signals may support mechanistic disturbance–recovery inference.
The broader ECHO chain and additional modules remain research/specification targets until their mathematical definitions, bindings, tests, provenance, and status are individually documented.

03 / Research-to-software traceability
The paper becomes an implementation contract
For DRIFT, theorem-level claims and non-claims are translated into stable software requirements and acceptance tests. Future development must preserve this chain rather than re-interpreting the science ad hoc.
Research object
Software consequence
Current status
Φ / spectral compression
Structural signal only; never label resilience from Φ alone.
SPECIFIED
DRIFT-M
Expose whether matching assumptions are independently justified or unresolved.
SPECIFIED
DRIFT-O
Report information loss and non-identifiability under partial observation.
SPECIFIED
DRIFT-R
Report robustness bounds when their required quantities are available.
SPECIFIED
DRIFT-I / N
Gate interpretation when coordinate invariance or local stationarity is not justified.

BenchEWS ECHO–DRIFT: From Spectral Compression to Disturbance–Recovery Inference
Structural, observational, and statistical identifiability limits of passive covariance. Mathematical basis of the DRIFT metrology module.
Concept DOIs are preferred for persistent links to evolving Zenodo records. Version DOIs remain visible for reproducibility. Future module papers and implementation milestones will be added here with their software role and status.
05 / Research decision · 20 September 2026
Adaptive Coverage — red-team decision
During development of BenchEWS Studio 3.0 / ECHO, a candidate Adaptive Coverage concept was subjected to successive adversarial mathematical gates. The proposed scalar Adaptive Coverage Index (ACI), and the later claim that Compression, Recovery and Task-Constrained Response Geometry form a novel three-axis theory, were not retained. Substantial parts are already covered by established controllability, robust-control, principal-angle and viability theory.

REJECTED
No new BenchEWS scalar metric claimed.

REJECTED
No new three-axis theory claimed.
Control & viability mathematics
REFERENCE
May be used as established diagnostic mathematics with attribution.
DRIFT
RESEARCH / SPECIFICATION
Retained as a metrological control layer for interpretation gates; no novelty claim for its established component mathematics.
Individual branch
EXPLORATORY
No clinical or psychiatric interpretation; no framework paper from the rejected C/R/G core.
What is BenchEWS development here? The documented contribution is the research process, the tested hypothesis, its rejection/reformulation, and the resulting ECHO/DRIFT architecture decision — not ownership of the established mathematics used in the audit.
06 / Development log
20 September 2026
Adaptive Coverage research branch frozen after mathematical red-team review: ACI rejected; C/R/G novelty rejected; established control and viability diagnostics retained as reference mathematics; DRIFT retained as a metrological control concept; Individual remains exploratory.
Scientific boundary: This archive documents intent, evidence and rejected hypotheses. It does not turn planned architecture into implemented or validated software.
