Education Tool Changelog Trust Playbook

The core insight

High-anxiety education tools will make mistakes. A public changelog turns frantic iteration into evidence; an error log turns prediction misses into learning; a postmortem turns angry users into the next cohort of trust signals.

What to publish

Publish model version changes, data-source changes, known edge cases, shift-level sample warnings, outage notes, prediction error ranges and result-day accuracy reports. Link these notes from calculator and predictor pages before users have to hunt for them.

Risk and reproducibility

This playbook is highly reusable, but only if the team is honest. Changelogs become liability when they hide failures, inflate accuracy or use vague language to avoid explaining data quality limits.

Search intent checklist

• Answer the practical builder question before discussing channels.
• Separate verified facts from estimates, directional third-party data and hypotheses.
• Include a risk section so readers can judge whether the playbook is safe to copy.
• Link to the growth hub and at least three adjacent playbooks for context.
