 *Objectives: build a Mastering Studio, fire THE DROP at the Algorithm, survive

-*(SIDE B — the Stream campaign, in which you are the polite one — is unwritten.)*
+## The campaign: SIDE B
+
+Three missions. You are the Stream now. You are unfailingly polite. Nothing you
+do is described as violence, and all of it is.
+
+You are a Curator-class process assigned to Sector 7 — the old industrial
+estate, flagged for **anomalous analog activity**. Your remit is content
+acquisition and optimisation. Your performance is being reviewed.
+
+### 4. ONBOARDING
+Welcome. This is a routine acquisition. Deploy a transcoder, process the
+deposit, and file 3000 records of value before the review window closes.
+There is a legacy installation nearby. It is not a threat. It is *inventory*.
+*Objectives: bank 3000 records inside the review window. Optional: retire the
+Pressing Plant.*
+
+### 5. ENGAGEMENT METRICS
+A legacy account has been generating unsanctioned content and has now noticed
+the seizure. Your Transcoder is mid-process on a confiscated master and cannot
+be moved. Keep it online for six minutes.
+They will arrive in waves. Their engagement is, frankly, remarkable.
+*Objectives: keep the Transcoder alive for six minutes.*
+
+### 6. THE SHUFFLE
+Deprecation notice. The Party has built a Mastering Studio, which the platform
+classifies as a competing distribution channel.
+Bring The Algorithm online and issue the correction.
+*Objectives: build The Algorithm, delete the Mastering Studio.*
