Day 0 - May 1, 2026: Building the Dashboard Factory

Today is the foundation day for 100daydash.blog, a public sprint to publish 100 dashboards in 100 days.

The goal is simple: each day should produce a useful data artifact and a short writeup that explains the question, data source, method, and result. Some days will be exploratory. Some will be polished. The important thing is that the workflow stays repeatable enough to survive the full run.

The project is organized as a small monorepo:

• web/ contains the Astro site, content collection, layouts, and public media.
• dashboards/ contains Python dashboard code, tests, data folders, and outputs.
• scripts/ contains local automation for creating and validating dashboard days.
• docs/ captures architecture, security, and development notes.

Before building dashboards, the focus was on hardening the foundation to ensure the system can scale across 100 consecutive days.

Hardening the CI/CD Pipeline

The first infrastructure pass focused on keeping the pipeline strict without introducing unnecessary noise. Gitleaks false positives were resolved so secret scanning can stay enabled, CodeQL was upgraded to v4, and the security checks were tuned to surface useful signals instead of routine lockfile and baseline churn.

GitHub Actions quality gates are passing, including tests and linting, which reinforces the project’s coverage and CI goals.

Security Baseline Improvements

The security baseline also now accounts for the UTF-8 encoding issue found during local scans. Directory exclusions keep .venv, lockfiles, and generated baselines out of scan paths, which keeps feedback fast while preserving reliable coverage for source, scripts, docs, and dashboard metadata.

Environment Consistency Across Machines

The development workflow is built around uv sync to manage the Python environment and pnpm install to manage Astro and frontend dependencies. Running the same setup commands on both the laptop and desktop prevents “works on my machine” drift and helps preserve the current 87% coverage baseline across machines.

The site is successfully deployed through Cloudflare Pages, matching the local-first workflow with a static deployed target.

The Day 0 dashboard folder lives at dashboards/day-000-introduction. It is intentionally lightweight: it proves the repo shape, test setup, and static output flow before the first real data dashboard begins.

Coverage and reproducibility are treated as first-class constraints from Day 0.

Definition of Done (Day 0)

• Daily dashboard creation is repeatable through local scaffolding and metadata validation.
• CI/CD quality gates cover formatting, linting, tests, security scans, and static site builds.
• Local laptop, desktop, and deployed environments remain reproducible from the same dependency files and setup commands.
