Singapore Education Cross-OS Failure Trace Library (EDU.SGP.TRACE) — Unified Spec v0.1

Purpose: A reference spine of reusable, non-emotive failure chains for Singapore’s education system.
Each trace is a mechanism, not an opinion.
Use: diagnosis, early-warning, comparison, and safe AI reuse across EducationOS → SchoolOS → TuitionOS.

VERSION CONTRACT (DO NOT EDIT RETROACTIVELY)

D) TUITIONOS INTERVENTION FAILURES (WHEN MISUSED)

TRACE.EDU.SGP.11 — Over-Practice Without Diagnosis

Zoom: Z1
Phase: P2 stagnation
Lanes: TUI.L04

Mode: II

TRACE.EDU.SGP.12 — Scope Creep

Zoom: Z1
Phase: P2→P1
Lanes: TUI.L03
Tripwire: EDU.S05
Chain: too many topics at once → load saturation → instability
Mode: II

TRACE.EDU.SGP.13 — Confidence Inflation

Zoom: Z1
Phase: P2 illusion
Lanes: TUI.L06
Tripwire: TUI.S05
Chain: easy drills → false confidence → exam shock
Mode: II

TRACE.EDU.SGP.14 — Latency Not Reduced

Zoom: Z1
Phase: P2 risk
Lanes: TUI.L02
Tripwire: EDU.S01
Chain: slow correction → backlog → compounding gaps
Mode: II

E) TIME & VOLATILITY

TRACE.EDU.SGP.15 — Exam-Condition Collapse

Zoom: Z1
Phase: P2→P1
Lanes: EDU.L04, TUI.L05

Mode: II

TRACE.EDU.SGP.16 — Marks Volatility

Zoom: Z1
Phase: P2 instability
Lanes: EDU.L07
Tripwire: TUI.S02

TRACE.EDU.SGP.17 — Teacher Load Saturation

Zoom: Z2
Phase: P2→P1

HOW TO USE THIS LIBRARY

Match earliest tripwire to live signals.
Select the trace whose chain fits observed propagation.
Identify violated boundary (latency, retention, transfer, load).
List repair knobs (scope control, spacing, diagnostics, transfer drills).

CANONICAL REUSE PROMPT (FOR AI)

“Given EDU.SGP sensors, match earliest tripwire to EDU.SGP.TRACE, output likely failure chain, identify violated safety boundary, and list TuitionOS repair knobs. Keep policy facts separate from CivOS interpretation.”
