PRIMARY_LATTICE_READ:
BukitTimahTutor Forecast-and-Scorecard is not a generic blog page.
It is a Z2/P3 control-and-validation node that converts Math diagnosis and intervention into bounded future predictions, then checks those predictions against reality.

ONE_SENTENCE_DEFINITION:
BukitTimahTutor Forecast-and-Scorecard Series v1.0 is the public runtime layer that predicts what kind of Math improvement should appear by a named horizon, then checks later reality against that prediction and updates route decisions accordingly.
CLASSICAL_BASELINE:
Most tuition sites report results after they happen. A stronger runtime forecasts bounded improvement first, then later checks whether the forecast was correct, partially correct, or wrong.
WHY_THIS_NODE_EXISTS:
- to prove the runtime is not only descriptive
- to show that diagnosis changes future expectations
- to make intervention logic testable
- to distinguish projection from hindsight
- to improve route fit over time
- to build public proof loops for BukitTimahTutor.com
CORE_RUNTIME_LAW:
A forecast node is valid only if:
1. the present condition is named clearly
2. the target horizon is explicit
3. the intervention corridor is stated
4. the expected change is bounded
5. the later outcome is actually checked
6. the scorecard can downgrade or re-route the original claim

- S4: [BTT.EduOS.MathOS.Z2.P3.Cohort.S4_PrelimRunway.Forecast]
PARENT_VISIBLE_READ:
A good forecast page should tell a parent:
- where the child is now
- what is breaking
- what should improve next
- by when it should improve
- how we will know if it is improving
- what we will do if the forecast is wrong
WHY_THIS_NODE_IS_STRUCTURALLY_STRONG:
- it sits at Z2 where institution-level route changes can actually be made
- it reaches down to Z0 where real student change happens
- it interfaces with Z1 where trust and continuation decisions occur
- it binds upward to Z3 where school and exam reality judge the forecast
- it uses P3 logic because it is a stable repair-and-projection organ, not a vague motivational page
FAILURE_TRACE:
WEAK_FORECAST_RUNTIME:
- diagnosis vague
- horizon vague
- intervention vague
- no earliest visible signals
- no scorecard later
- parent trust decays
- route errors persist
- site becomes claim-heavy and proof-light
REPAIR_CORRIDOR:
- name state more precisely
- reduce forecast to bounded horizon
- specify observable early signals
- attach scorecard date
- publish or log later outcome
- re-route if mismatch remains
EDUCATIONOS_READING:
This node is the public projection-and-verification organ of the BukitTimahTutor Runtime. It turns present-state diagnosis into bounded future expectations, then checks whether learning actually moved as expected.
MATHOS_READING:
This node treats mathematical improvement as forecastable movement across concept, method, transfer, timing, and confidence dimensions. It validates improvement through later scorecards rather than relying only on retrospective claims.
FAVORABLE_OUTCOME:
- parents see a usable, testable system
- tutors get explicit forecast discipline
- route-fit improves over time
- Evidence Ledger gains stronger proof traces
- BukitTimahTutor.com becomes more visibly runnable as a bounded Math runtime
FAILURE_MODE:
Without this node, the site remains mostly retrospective. It can describe improvement after the fact, but cannot prove that its diagnosis and intervention logic had real forward predictive value.
