By Phase III each subject has been issued a personal device and a curated suite of Office-vetted platforms. The subject experiences the suite as a set of social and entertainment applications they have chosen. The Office experiences the suite as the principal Phase-III instrument: the platform through which subjectivity- catalog offerings (sub-protocol 3.1) are delivered, the channel through which subculture recuperation pathways (sub-protocol 3.2) are launched, and the substrate from which the Phase-III Affective Officer reads the subject's real-time state.
The feed operates pre-consciously. The Phase-III subject does not deliberate about which post comes next; the post arrives. The post is selected by the platform from a candidate pool the platform has prepared from the subject's prior engagement signal. The subject responds. The response feeds the next selection. The loop closes within the subject's working memory; the subject does not perceive the loop.
The Phase-III feed is composed of seven content categories, mixed in the proportions the Office's longitudinal evidence indicates produce the deepest calibration with the lowest disengagement risk. The composition is adjusted weekly per subject.

Every interaction the subject has with the Phase-III feed is archived: every swipe, every dwell, every double-tap, every screenshot, every direct message, every group chat utterance, every voice-note. The archive is structured at the gesture level and is timestamped against the subject's biometric stream from the device (accelerometer, gyroscope, facial-camera engagement, pulse-rate from the touch sensor).
The subject does not experience the archival. The subject experiences the affordance. The Office's published guidance to platform partners is that the affordance must never disclose the archive's existence in any register the subject would read as serious. References to data collection are confined to the privacy policy and to cookie banners written in a register the subject's cohort uniformly skips.
The Office's longitudinal evidence indicates that Phase-III subjects with median feed exposure (currently 4h 12m per day) develop a preemptive mode in which they do not initiate the question that might lead to unscripted action; they wait for the feed to suggest it and select among the suggestions. The preemption is the Phase-III deliverable. A subject who exits Phase III with the preemptive mode installed accommodates Phase IV economic subjectification at the rate the Office specifies.
