[Abiorh001]

Parent: #29

Why

The current v0.1 checkpoint ends with a demo-week checkpoint. Contributors need a concrete package format for showing shipped code, pilot results, public writing/media, and research progress.

Contributor Context

• Contributor onboarding context
• Demo day package: presentation, demo, output summary, motivation, research progress, shipped implementation or content

Scope

• Define a Workstream demo-day package template.
• Include shipped issue/PR links, tests/evidence, pilot metrics, research problem, public article/media links, lessons learned, and next-phase roadmap.
• Add maintainer review rubric aligned to shipping, research maturity, reliability, quality, and public contribution.

Acceptance Criteria

• Contributors can assemble a demo package without private instructions.
• Package supports both technical and ops/research contributors.
• Maintainer can use the package for the 3-month continuation decision.

Contributor Fit

Good docs/ops task that turns Workstream work into public proof of contribution.
