Metrics Dashboard

Purpose

Metrics Dashboard is the iteration-level measurement summary. Its unique job is to compare current metric values against explicit baselines, interpret direction and tolerance, and produce a clear decision about improvement, regression, or noise.

For how this artifact relates to metric definitions, security-metrics, and the improvement backlog, see the “Metric Four-Way Slice” section of workflows/activities/06-iterate/README.md.

# Metrics Dashboard: DepositMatch CSV Import Pilot Readiness

**Review Window**: 2026-05-05 - 2026-05-12
**Baseline**: FEAT-001 pre-release benchmark floor from 2026-05-05
**Status**: complete

## Decision

The latest change improved CSV import validation time and remains within the
FEAT-001 performance target. No performance backlog item is required for this
metric. Continue monitoring during pilot rollout.

## Summary

The representative 10,000-row CSV import validation benchmark improved from
5.8 seconds to 4.4 seconds. The current value is below the 5-second target and
outside the 5% noise band, so the result counts as a meaningful improvement.

## Metrics Table

| Metric | Baseline | Current | Direction | Result | Source |
|--------|----------|---------|-----------|--------|--------|
| `csv-import-validation-seconds` | 5.8 seconds | 4.4 seconds | lower | pass / improved | `docs/helix/06-iterate/metrics/csv-import-validation-seconds.yaml`; `pnpm metric:csv-import-validation -- --fixture fixtures/import/acme-10000-rows` |

## Interpretation Rules

- Values within 5% of baseline are treated as noise.
- Values above 5 seconds violate the FEAT-001 performance target and create an
  improvement backlog candidate.
- Values below target but worse than baseline by more than 5% create a watch
  item, not an automatic build task.

## Trend Notes

- Validation improved after switching row checks to batched normalization before
  persistence.
- No corresponding increase in upload API 5xx rate was observed in staging.
- Pilot rollout should still watch p95 upload response time because production
  file sizes may differ from fixture data.

## Follow-Up

- No immediate improvement issue.
- Continue pilot monitoring through the deployment checklist signals.
- Re-run the benchmark after adding column mapping and row-level validation
  stories.

## Review Checklist

- [x] Baseline is explicit
- [x] Each metric cites a source
- [x] The summary states the decision implication

# Metrics Dashboard Generation Prompt

Document the iteration-level metrics summary used to judge whether the latest
changeset improved the system.

## Purpose

Metrics Dashboard is the **iteration-level measurement summary**. Its unique
job is to compare current metric values against explicit baselines, interpret
direction and tolerance, and produce a clear decision about improvement,
regression, or noise.

For how this artifact relates to metric definitions, security-metrics, and the
improvement backlog, see the "Metric Four-Way Slice" section of
`workflows/activities/06-iterate/README.md`.

## Reference Anchors

Use this local resource summary as grounding:

- `docs/resources/google-sre-monitoring-distributed-systems.md` grounds
  dashboard summaries as interpreted quantitative signals with clear sources.

## Focus
- Start from the canonical metric definitions in `docs/helix/06-iterate/metrics/`.
- Compare the current measurement against the previous baseline or committed floor.
- State whether the change improved, regressed, or stayed within noise.
- Include only the metrics needed to support the decision.
- Cite the source of each metric and the measurement command or report.
- Keep raw observability setup and implementation details out of this artifact.

## Boundary Test

| If you are writing... | Put it in... |
|---|---|
| Metric unit, command, tolerance, and labels | Metric Definition |
| Current-vs-baseline interpretation for one iteration | Metrics Dashboard |
| Prioritized follow-up work | Improvement Backlog |
| Alerting or dashboard implementation details | Monitoring Setup |

## Completion Criteria
- Every metric cited has a source definition and current value.
- The comparison baseline is explicit.
- The conclusion is actionable and easy to hand to the next iteration.
