3) Canonical Intake Block (Copy-Paste, Public-Facing)

Paste this block into your “Start Here” page. This is your universal prompt entry gate.

SG-EDU Intake v0.1 (Student / Parent)

Fill in plainly:

Student

Age / Level: (K1/K2/P1–P6/S1–S4/JC1–JC2/ITE/Poly)
School type: (Mainstream / IP / IB / International / Private)
Subject focus: (Eng/Math/Sci/Hum — pick 1–2 priorities)
Current results: (grades or last test score)
Exam horizon: (PSLE / O-Level / N-Level / A-Level / None yet)
Time available: (hrs/week)
Tuition: (Yes/No; how many hrs)
Parent support: (Low/Med/High)

State Sensors

Phase (pick): P0 / P1 / P2 / P3
TTC (time-to-core test): 1–2w / 4–6w / 8–12w / 12w+
Backlog load: Low / Med / High
Stability under timed work: Stable / Shaky / Collapse

Goal

Target (optional): e.g., “A1 English”, “IP track stability”, “JC readiness”
Career direction (optional): Doctor/Lawyer/Engineer/Designer/Unknown

4) Canonical Output Block (What the system must return)

Every run must return exactly these sections:

Output v0.1

State Summary (Stage×Phase×TTC×Backlog)
Primary Failure Mode (1) + Secondary (optional)
This Week Plan (3–5 actions only)
4-Week Plan (milestones)
Simulation Schedule (timed tests + thresholds)
HGW Forecast (4w & 12w)
Risk Flags (collapse signatures)
Repair Routing (which node packs to use)

5) Routing Algorithm v0.1 (Deterministic Rules)

5.1 Phase-first gating

If P0: stop expanding. Repair foundations only. Reduce scope.
If P1: controlled rebuild + short loops + frequent measurement.
If P2: scale volume + timed load training + widen topics.
If P3: optimise + stretch goals + competition/excellence.

5.2 TTC rule (time-to-core)

TTC 1–2w: emergency triage; only highest-leverage nodes.
TTC 4–6w: repair + timed load entry.
TTC 8–12w: rebuild + transfer training + full simulations.
TTC 12w+: deep capacity build; widen lanes safely.

5.3 Backlog rule

High backlog: cut new content; clear core nodes first (minimum viable).
Low backlog: allow breadth expansion.

5.4 Timed-load rule

If timed work collapses: route to ExamSim micro-steps + checklist + rewrite loop.

6) Failure Mode Trace v0.1 (required in every run)

Non-emotive schematic trace:

Example template:

			
Z0: weak retrieval under time
→ Z1: weekly plan not enforced
→ Z2: timed-load collapse (ExamSim fail)
→ Z3: lane instability (English writing unreliable)
→ Outcome: grade volatility + exam risk
Repair:
Z1 routing + Z2 simulation ladder + fenced fix pack
→ regain P2 stability within TTC window

		

7) The “3-Minute Weekly Check” (Control Loop)

Run every week, same day:

Inputs

What was planned? (3–5 actions)
What executed? (%)
Timed micro-test result
Biggest failure mode observed
Next week capacity (hrs)

Outputs

Keep / Cut / Replace actions
Add one repair node
Schedule one simulation

This keeps Phase from drifting.
