Observability for a Delivery Pipeline, Not Just the App
A signal catalog for the pipeline itself: which stage emits each signal, who consumes it, and what to alert on. Standardized where it can be, honest where it is not.
Recording AI Authorship in Provenance You Can Trust
Co-authored-by is the wrong trailer for AI: it is human credit, and tools get it wrong. Use a dedicated Assisted-by trailer, carried into signed provenance.

Coding-agent evaluation, Copilot governance, Claude model policy, secret exposure, API access limits and soil sensing finance defined the developer week.
Honest DORA: Define a Deployment Before You Measure
Every DORA metric counts deployments, but DORA never defines one. Pin it down, instrument all five metrics, decompose lead time, and segment by AI cohort.

Friday Roundup - Week 26: Control Moves From Cooperation to Enforcement
Agent safety research says cooperation is not control, coding tools fenced off what agents can reach, and APIs and farm sensors became evidence surfaces.
Produce a Software Bill of Materials You Can Actually Use
A useful software bill of materials is in a format your tools read, bound to the exact digest that ran, and re-scannable without a rebuild. Produce one anyway.
