Product Proof

The example product is Tagnova. It is concrete enough to test the system and narrow enough to teach the process clearly.

If a reader does not understand a term in this proof path, Ask the wiki in the header can explain the relevant repo or platform concept from the approved sources before they continue. That assistant is currently powered by Mistral and is limited to the approved wiki and repo corpus.

1. Goal

The goal is not to celebrate one product. The goal is to prove that the global system is teachable, repeatable, and useful for the next product too.

The proof question is:

• can the global system carry a new product from Provider Baseline to Launch

2. Proof Standard

The proof standard is strict:

• provider and domain prerequisites must be explicit before bootstrap
• product intent must be explicit before code
• requirements must be explicit before architecture
• architecture must be explicit before planning
• readiness must be explicit before implementation
• if the product exposes a missing global rule, the rule is fixed globally first

3. Proof Map

Use the proof section in this order:

1. Product Proof Setup
2. Product Proof Walkthrough
3. Product Proof Status

Those pages answer three different questions:

• what must exist before the machines can work
• how the proof path is executed step by step
• what is already proven and what is still open

4. Example Product

The current example product is Tagnova.

Tagnova is a calm digital news product. Its launch idea is a daily curated edition for Vienna, Munich, and London, with a simple member path for saving stories and returning to them later.
