Add metrics frontmatter and session-close recording to tdd-workflow,
document the reference implementation in wiki/AboutKaizenAgents.md,
and add an e2e test covering record → show → optimize → brief.
Persist INTENT and ecosystem assessments in history/, add ADR-004 for
project metrics with Helix Forge correlation, and register WP-0003 and
WP-0004 workplans with State Hub. Update SCOPE, README, and agency-framework
docs to reflect the two-layer measurement model.
