Work with a boundary.

Each practice can start as a diagnosis. None of them is a catalogue of tools.

Choose the pressure you actually feel.

Open the practice that matches the decision. The others stay available.

Strategy, pyramid, shift-left, and the layers between a unit test and a production journey.

Whether CI is a signal or a ceremony, and what a gate is allowed to block.

Models, retrieval, tools, MCP, and the evaluations that tell you the system is still grounded.

Integration and service boundaries for teams that cannot test everything against live dependencies.

Boundaries, contracts, and a release you can reverse.

Threats, access, secrets, and checks on the path to release.

WCAG 2.2 AA as a design target, with manual proof. Not a certificate.

Signals, alert routes, and a record of the incident. No uptime number.

Flaky tests kept visible, with an owner, an expiry, and a separate verifier.

Diagnostic, architecture, or implementation with the team. We confirm fit before scope grows.

One problem, read-only where possible, with a written view of cause and next step.

A design the team can carry: layers, gates, data, and the risks left open on purpose.

Build with the people who will maintain it. Handover is part of the work, not a slide at the end.

Describe the release friction. We will point at one starting point, or say we are the wrong firm.
