Start at developer-docs/index.md.
Before editing documentation: read developer-docs/documentation-policy.md.
For architecture or testing work, also read:
- developer-docs/decisions.md:
AD-<number>decision log - developer-docs/testing/iteration-vocabulary.md: work type, tier, and queue field identifiers
- developer-docs/testing/change-authoring-workflow.md: verified change loop
- developer-docs/work-queues/playwright-e2e-smoke.md: active Playwright backlog
Before commit or push on dependency, CI, workflow, or e2e/example changes: complete developer-docs/playbooks/change-authoring-verification.md (AD-10). Dependency bumps: also dependency-update-verification.md.
Human onboarding (commands, emulator): LOCAL_DEVELOPMENT.md owns that content; do not duplicate here.
