Evidence Based Finish

Build DoneSignal, a private completion planner in one HTML file. Freeze must-have criteria and their prerequisites, attach current evidence, and see whether a project is ready. Reopening a prerequisite makes verified descendants stale until rechecked. Track work rounds and preserve the time spent polishing after readiness, even if work reopens later. Includes a worked demo, local saving, validated JSON backups and Markdown briefs. Customize style and sample audience. Evidence is user supplied.
