You Own the Release

Episode 1

Stop Deploying by Memory

Branch protection with a required review and a required status check that actually blocks an unready merge; reading the commit/PR audit trail to find who changed what and when; using it to diagnose and recover from an unreviewed regression; team-scale collaborator roles.

Episode 2

From Commit to Candidate

CI/CD stages and explicit dependencies; triggers; dependency-cache keys; artifact and commit traceability; inspect repeat-build evidence while accounting for mutable external inputs and environment differences.

Episode 3

The Environment Is Part of the Code

Infrastructure as code: parameterised templates, declared-versus-observed state, reviewed plans, scoped deployment identities and workload federation; distinguish fixture snapshot restore from a production rollback or backup strategy.

Episode 4

The Security Gate Says No

Security and compliance gates in a delivery pipeline: separating blocking risk from noise; scanning shipped dependencies against advisories at a chosen severity; checking where a dependency came from; scoped, short-lived pipeline credentials; independent approvals; rotating an exposed secret; and keeping scan evidence linked to a traceable artifact.

Episode 5

The Tests Passed. The AI Got Worse.

Separate unit, integration, security and AI-evaluation gates; AI-quality metrics with sample size and margin of error; conservative thresholds; holdout contamination; releasing gradually with a canary; rolling back to the last known-good release; and recording a release decision that says what the measurement can and can't support.

Episode 6

Creator Night: The Feed Is Failing

Incident response under pressure: ordering actions into stabilise, diagnose and follow up; scoping a failure from logs; recording hypotheses with evidence; mitigating with a verified rollback; reasoning about a latent defect and the missing guard that spread it; communicating accurately without overclaiming; and writing a blameless, checkable incident record.

Episode 7

Creator Night: The Bill and the Breach

Bounded incident evidence, least-privilege containment and approval checks; capacity controls distinct from budget alerts; distinguish attack traffic from a client fault; test retry and cost changes and record the security and cost findings.

Episode 8

You Are the Engineer

Owning an engineering recommendation end to end: clarifying a brief into constraints, gaps and assumptions; building and testing a safe core; securing and staging a release through the gates; diagnosing an unfamiliar fault; and defending a release decision language by language with evidence, a tested rollback and an operational handover.
