H015 Review

• Hypothesis ID: H015
• Name: Measurement Instrument Reliability
• Current statement: The packet-based instrument can collect comparable procedural outputs reliably enough for bounded research use.
• Research question: Is the ECR-000003 instrument reliable enough to support review and next-step experimentation?
• Prior direction and strength: active / moderate
• Prior kill-condition status: not_tested

Evidence Supporting

• All ECR-000003 datasets were normalized, certified, and compared under frozen Comparator 3.1.0. Sources: research/evidence-runs/ECR-000003-representation-sensitivity/response-filename-verification-report.md, research/evidence-runs/ECR-000003-representation-sensitivity/normalization/CERTIFICATE-INDEX.md
• Official outputs, explainability outputs, and experiment EDRs exist for all three experiments. Sources: research/evidence-runs/ECR-000003-representation-sensitivity/pipeline/generated/ecr-000003-final-readiness-report.md, research/evidence-runs/ECR-000003-representation-sensitivity/comparison/comparator-3.2-explainability-implementation-report.md

Evidence Challenging

• Tolerant parsing remained necessary across all three experiments. Source: research/evidence-runs/ECR-000003-representation-sensitivity/pipeline/generated/ecr-000003-comparison-summary.md
• Explainability still surfaced many high-priority differences requiring human review. Source: research/evidence-runs/ECR-000003-representation-sensitivity/comparison/ECR-000003-explainability-summary.md

Mixed Evidence

• The instrument is operational and repeatable enough to support governance review, but not strong enough to remove human interpretation or comparator caveats.

Provider, Representation, and Domain Effects

• Reliability appears stronger for data collection completion and output comparability than for semantic equivalence at detail layers.

Relevant Instrument Findings

• Comparator 3.1.0 is frozen for accepted ECR-000003 measurements.
• Comparator 3.2.0 provides auxiliary explanation without replacing accepted outputs.

Threats

• schema effects
• comparator adapter issues
• tolerant parsing events
• no accepted human benchmark

Alternative Explanations

• Apparent reliability may mostly reflect strict packet structure and file-normalization workflows rather than true semantic stability.

Kill Condition

• Current kill condition: JSON validity, schema compliance, and agreement collapse across runs.
• Status: tested_not_met

Proposed Direction

supported

Proposed Evidence Strength

moderate

Board Recommendation

retain

Rationale

Within the narrower claim of bounded research use, ECR-000003 supports the instrument more than it weakens it.

Next Evidence Needed

• human baseline comparison
• negative non-isomorphic controls
• constraint-layer calibration
