SG EducationOS Auto-Calibration + Cohort + World + Career Coupling

Unified Upgrade Layer v0.2

This is not four features.
This is one integrated control architecture.

1️⃣ AUTO-CALIBRATION LAYER v0.2

(Makes forecasts defensible over time)

Purpose

Adjust thresholds automatically using real outcomes.

Without this → forecast is static.
With this → forecast becomes adaptive.

1.1 Calibration Inputs

Collected weekly:

Simulation pass rate (%)
Execution rate (% of weekly plan completed)
Rewrite count
Mistake recurrence rate
Grade deltas (if available)
TTC reduction progress

1.2 Calibration Rules

Rule A — Overprediction

If:

HGW forecast predicted improvement
AND
Simulation score stagnates 2 weeks

Then:

Reduce Hope weight by 1
Increase Grind sensitivity
Raise minimum execution threshold

Rule B — Underprediction

If:

Execution ≥ 85%
Simulation ≥ 75%
Mistake recurrence decreasing

Then:

Increase Hope weight
Expand difficulty band

Rule C — Drift Spike

If:

Simulation < 60% twice
Grind < 2
Then:
Lock system to P1 mode
Cut expansion nodes

1.3 Output Adjustment

Every 4 weeks:

System prints:

			
Calibration Adjustment:
Hope weight: +1 / 0 / -1
Grind threshold: 70% → 80%
Simulation frequency: 1x → 2x

Now your forecasts evolve with reality.

2️⃣ COHORT MODE (Tutor Control Panel)

This turns EduKateSG into an operations dashboard.

2.1 Cohort Table Structure

For each student:

Student	Phase	TTC	Backlog	Timed Stability	HGW Score	Risk

2.2 Cohort Routing Logic

If >30% of cohort in P1:

Curriculum pacing too fast.
Reduce breadth.
Reinforce core nodes.

If >40% shaky timed stability:

Increase simulation drills.
Reduce passive homework.

If >20% Grind ≤2:

Execution enforcement failure.
Adjust weekly structure.

Now tuition is run like a system, not reactive tutoring.

3️⃣ WORLD MODE (Instance Swap Engine)

You already built Z5/Z6 templates.

Now we activate instance swapping.

3.1 Mode Switch

			
EducationOS Mode:
[ SG ]
[ NYC ]
[ LON ]
[ TYO ]
[ BJS ]
[ SEL ]

		

Switching mode changes:

Admissions gates
Exam structure
Lane emphasis
Stability pressures

Routing logic remains identical.

3.2 Comparative Output Extension

Add section:

			
Cross-City Variance Check:
SG Stability Index: High
NYC Variance Index: Moderate
TYO Load Intensity: High

This makes the comparative engine operational.

4️⃣ CAREER TARGET COUPLING v0.2

This connects Student State → Long-Horizon Role Fit.

4.1 Two Entry Paths

A) Target-First Mode

Input:
“I want to be a Doctor.”

System maps:

Doctor → Science lane strength → P2+ minimum → Timed stability high → Long TTC training window

Then back-propagates weekly plan.

B) Skill-First Mode

Input:
“I’m strong in analysis, weak in writing.”

System outputs:
Likely role fit: Oracle-leaning
Potential lanes: Data, Law, Policy, Engineering

Then builds dual track:
Current stability + career exposure micro-block.

4.2 Role Mapping (Visionary / Oracle / Operator)

Add to output panel:

			
Role Trajectory Signal:
Current: Operator-leaning
If Grind + Wisdom rise → Oracle shift possible
If Hope stable + strategic thinking → Visionary candidate

This adds depth without speculation.

5️⃣ UNIFIED OUTPUT PANEL v0.2

Now the panel returns:

State Summary
Failure Mode
Weekly Plan
4-Week Target
Simulation Schedule
HGW Forecast
Risk Flags
Repair Routing
Calibration Adjustment
Role/Career Signal
(Optional) Cross-City Variance

Still one panel.
But fully upgraded.

6️⃣ WHAT JUST CHANGED STRUCTURALLY

You now have:

Deterministic routing
Adaptive calibration
Cohort control
Cross-country instantiation
Career horizon coupling

This is no longer tuition.

This is a:

Multi-Scale Education Coordination Engine.

7️⃣ What Comes After This (Real “Next”)

The real next is not adding more features.

It is:

Data accumulation + first published backtest case.

Because the moment you show:

Intake
Plan
12-week run
Forecast
Outcome
Calibration update

The system becomes credible beyond explanation.
