## Summary
TIME_SERIES_OPS_EVAL_V1. Keep forecasting, anomaly detection and predictive-maintenance decisioning distinct, with timestamp/data-quality/calibration/regime context and baseline comparison.

## Current judgment
TIME_SERIES_OPS_EVAL_V1. Keep forecasting, anomaly detection and predictive-maintenance decisioning distinct, with timestamp/data-quality/calibration/regime context and baseline comparison.

## Scope
Time-Series／Operations AI

## Confirmed

## UNKNOWN
- EA-076-UNKNOWN-01: preserve all authority OPEN_UNKNOWN and availability gates.
- EA-076-UNKNOWN-CURRENTNESS: 外部根拠の再確認日がcanonical body/control-planeで確定していないため、currentnessはUNKNOWNとして保持する。日付を推測補完しない。

## Evidence
- EA-076-R11-RESEARCH (RESEARCH): EA-076 監査済みresearch / canonical revision binding
- EA-076-R11-WEB-READBACK (IMPL): EA-076 Web body identity / canonical readback

## Practice
TIME_SERIES_OPS_EVAL_V1. Keep forecasting, anomaly detection and predictive-maintenance decisioning distinct, with timestamp/data-quality/calibration/regime context and baseline comparison.
## Practice
TimesFM/Chronos-style TS foundation models are implementation classes, not universal winners. Current TimesFM 3.0 weights remain non-commercial/non-production; tenant workload backtest remains mandatory.

## OPEN_UNKNOWN
preserve all authority OPEN_UNKNOWN and availability gates.

## AUDIT BOUNDARY
