1 — Continuous Integration
Merging and testing changes continuously so integration problems surface in minutes, not in the multi-day merge conflict that used to be normal.
10 — Supply Chain Security
SBOMs, artifact signing, and provenance attestation — verifying what's actually being deployed is what was actually built, not something injected in between.
2 — Continuous Delivery
Keeping every merged change in a deployable state, which is the precondition every other release-engineering practice in this Part builds on.
3 — Deployment Strategies
The spectrum from all-at-once to fully progressive rollout, and the blast-radius-vs-speed trade-off each point on that spectrum makes.
