CI/CD Quality Gates Reference Implementation

Portfolio Role

This repository is the governance decisioning part of the portfolio story. It shows how metrics, integration evidence, and policy combine into explicit PASS, WARN, or BLOCK release outcomes.

Profile Map

• Portfolio narrative: governance decisioning
• Skill signal: release governance and CI/CD quality gates
• Review focus: threshold policy, combined report input, and auditable readiness decisions
• Evidence anchor: docs/evidence-integration.md

Business Value

• Converts abstract quality discussions into explicit pass or fail policy.
• Produces an auditable readiness report that can be attached to release approvals.
• Makes threshold governance reproducible in local and CI execution.
• Consumes upstream integration-suite decisions to produce cross-repo release governance.

What This Proves

• You can embed quality checks directly into delivery pipelines.
• You understand release governance, thresholds, and actionable failure signals.
• You can design quality gates that teams can actually operate.

Included in Day 1

• Pipeline templates for GitLab and Jenkins
• Smoke test and gate scaffolding
• Threshold configuration files
• Documentation for quality policy and release criteria

Quick Start

./run-tests.sh

Windows alternative:

python scripts\evaluate_gates.py sample-data\metrics.json

With integration suite input:

python scripts\evaluate_gates.py sample-data\metrics.json sample-data\integration-suite-report-pass.json

Demonstrable Behavior

1. Evaluates real sample metrics.
2. Optionally evaluates integration-suite report outcomes from another repository.
3. Writes a release-readiness report to the reports folder.
4. Returns PASS, WARN, or BLOCK based on combined governance rules.

Core Files

• scripts/evaluate_gates.py
• sample-data/metrics.json
• sample-data/integration-suite-report-pass.json
• sample-data/integration-suite-report-warn.json
• gates/thresholds/performance-thresholds.json
• gates/thresholds/quality-policy.yaml

Evidence

1. Base metrics evaluation: docs/evidence.md
2. Cross-repo integration governance: docs/evidence-integration.md

Roadmap

1. Add pipeline stages for build, smoke, performance, and accessibility
2. Add threshold policy evaluation
3. Publish reports and release readiness summary
