Architecture Decision Records

Accepted architecture decisions for IBEX Harness — auth, proxy, migrations, observability, and docs site.

Architecture Decision Records

Durable technical decisions for IBEX Harness. Each ADR captures context, the decision, and consequences.

Browse the sidebar for available records through ADR-0084 (including the proposed G0 principal and agent-binding contract). Numbers are not contiguous — ADR-0036 and ADR-0037 are not published.

For contributors: edit docs/app/content/docs/adr/ and run pnpm exec fumadocs-mdx in docs/app/.
