Z0  Physics        : anti-decay law (Acquire–Retain–Transfer)
Z1  Person         : self anti-decay (Health, Money, Judgement, Meaning…)
Z2  Family         : intergenerational transfer + buffers
Z3  Community      : P2 density, repair speed
Z4  Institutions   : throughput accelerators (schools)
Z5  City/Nation    : coordination stability under variation
Z6  Civilisation   : HRL regeneration engine

Z5.EDU_OS.SG :=
    city-scale capability regeneration
    that maintains population P2
    across shocks, variation, and lifecycle transitions

Health_P2_population
Money_P2_population
Digital_Judgement_P2_population
Civic_Judgement_P2_population
Resilience_P2_population
Meaning_P2_population

credential_rich
but judgement_poor
→ policy instability
→ misinformation amplification
→ coordination friction

high_institution_trust
strong_public_infrastructure
fast_truncation_capability

life-lane education outside schools
self-repair capability at Z1

city remains stable under:
    - health shocks
    - economic volatility
    - information attacks
    - demographic transitions

Q1: Can I do this calmly when untimed?
    NO  → Retention or Z0 gap
    YES → Q2
Q2: Can I do it under normal time?
    NO  → Execution or Control
    YES → Q3
Q3: Can I do it when conditions change?
    NO  → Transfer failure
    YES → P2 stable

Retention   → Spacing + tiny routines
Transfer    → variation drills + rule naming
Execution   → one-change-per-line + checklist
Control     → pause + triage + micro-plans

Day 0: diagnose + truncate
Day 1–2: untimed perfect reps
Day 3–4: spaced recall + light variation
Day 5: mixed probe
Day 6: light pressure (if safe)
Day 7: audit + stitch

CivOS Rate Law:
    decay_rate > regeneration_rate → collapse
Education OS:
    raises regeneration_rate at Z1–Z3
HRL Law:
    civilisation stability = pipeline continuity
Education OS:
    maintains human pipelines
Truncation/Stitching:
    early cut + rejoin safe path
Education OS:
    Z0 localisation + 7-day repair
Over-Concentration Brittleness:
    elite skill ≠ population stability
Education OS:
    distributes P2 capability
Shock Arrow Law:
    shocks test lattice, don’t define outcome
Education OS:
    thickens lattice pre-shock
