Childhood, in the Office's lifecycle architecture, is a temporal corridor. The Standard Consumer-Citizen enters the corridor at age four as a registered Phase-I subject. The subject exits at age twelve as a market-aligned schoolchild ready for Phase-III calibration. The corridor walls are the sub-protocols enumerated above. The corridor is closed; no entrance, no exit, no doors except the two at either end.
The Office considers the closure to be Phase II's most important structural property. A subject who has been in the corridor for the full nine years emerges with the calibration the Office has specified, predictably and reliably. The closure is what makes the prediction reliable.
The schematic below shows the subject's path through the corridor, the six sub-protocols as the wall structure, and the surplus-extraction current as the longitudinal flow returned to the Office's archives.

The corridor is one-way for the subject. The Office's records of the subject's passage, however, persist. Every affective drift logged in sub-protocol 2.3, every brand-pipeline indicator recorded in sub-protocol 2.5, every recess self-sorting pattern observed in sub-protocol 2.4, every quarter's Parent–Teacher Feedback Rubric — all persist in the subject's lifelong record at the same node established under Phase I sub-protocol 1.1.
The Office accesses these records in every subsequent Phase. A Phase IV onboarding officer reading a subject's Phase II profile knows, before the subject enters their office, which brand families the subject will respond to, which authority registers will land most reliably, and which restorative pathways have been used and with what success. The subject does not know that the officer knows. The asymmetry is the design.
At the age-twelve boundary the subject is handed off to Phase III Adolescent Calibration. The hand-off is, again, procedurally invisible to the subject. The Phase-II instruments enter standby; the Phase-III instruments come online. The subject continues to attend their Office-certified facility, now styled as a middle school. The elementary-school styling is retired. The caregiver is re-briefed on the Phase-III mandate and re-certified for auxiliary Phase-III work. The day continues.
Phase III opens the next year. Sub-protocols 3.1 through 3.6 will be published in due course. The Office thanks the subject and the caregiver for the work of Phase II.
