Summary

• replace the weekly full-suite monitor that timed out on every run with an hourly, two-path SDK synthetic
• fail loudly when the monitor credential is missing and retain privacy-safe JSON receipts for 30 days
• cover latest price, bounded history, latency budgets, empty data, and secret redaction
• remove the undeployed Docker/Prometheus example that referenced missing files and printed part of the API key
• publish the actual alert/dashboard model and incident runbook in the SDK docs

Verification

• pytest tests/unit/test_synthetic_monitor.py -q --no-cov — 4 passed
• non-integration suite — 401 passed
• keyless demo contract — 4 passed against production
• authenticated synthetic — latest and five-record daily history passed; receipt validated as JSON
• Ruff check + format on changed Python files
• CI-equivalent source Ruff and mypy checks
• package sdist/wheel build
• MkDocs build
• workflow YAML parse + git diff --check
