Change Log August 31, 2026

Theseus and Cells: separation of concerns

A new strategy page draws the line between the developer platform and the infrastructure architecture — what each owns, and the contract between them.

Explanation

Platform bindings

One declarative interface, resolved per deployment target — and the rules for the Enterprise Platform Binding.

Explanation

Cellular architecture

Cells as the isolation boundary for all modular services.

How-to guides

Pass application configuration via Fairway

Declare app config once in your Fairway manifest and let every environment deliver it — a ConfigMap in-cluster, a baked profile on Runway, per-cell values on Cells.

Strategies

Feature Flag Strategy in Theseus

An overview of how feature flags will operate in Theseus for application developers

Strategies

Modular feature test isolation

Test every modular feature against its contracts: fakes for service dependencies, real infrastructure from Caproni, and no spun-up world.

Strategies

Co-located Grafana dashboards

Dashboards are part of the service: jsonnet in the service repo, compiled in CI, shipped in the Helm chart, and discovered by whatever Grafana lives in the cell.

Strategies

Separation of Concerns Between Theseus and Cells

Where the developer platform ends and the infrastructure architecture begins: what Theseus owns, what Cells owns, and the contract between them.
