build-review▌

Developer-experience audit that actually runs onboarding and documentation flows, measures time-to-happy-path, and compares reality against planning assumptions.

Debugging workflow with an explicit rule: no fixes until the root cause is understood. The flow is investigate, analyze, hypothesize, then implement.

Code-review pass focused on the actual diff, aimed at risks that often survive CI such as SQL safety, trust boundaries, and structural regressions.
