# Phase 17 Calibrated Release Selector

- Source phase: Phase 16
- Source guard status: `REVIEW_REQUIRED`
- Aggregate decision: `KEEP_BASELINE`
- Selected router: `baseline-minilm`
- Baseline router: `baseline-minilm`
- Candidate router: `finetuned-embedding`
- Approved for default: `False`
- Task count: 16
- Regression count: 2

## Policy

| Budget | Value |
|---|---:|
| max_regressions | 0 |
| max_negative_hit_delta | 0.0 |
| max_negative_accepted_delta | 0.0 |
| min_recall_at_5_delta | 0.0 |
| min_mrr_delta | 0.0 |
| min_ndcg_at_5_delta | 0.0 |

## Reasons

- source guard_status is not PASS
- regression_count exceeds policy
- negative_hit_rate delta exceeds policy
- negative_accepted_rate delta exceeds policy
- mrr delta is below policy
- ndcg_at_5 delta is below policy

## Task-level Decisions

`NO_CHANGE` is a task-level status only; aggregate release decisions are `APPROVE_CANDIDATE`, `KEEP_BASELINE`, or `REVIEW_REQUIRED`.
