# ----------------------------------------------------------------------
# 1) Classical Foundation Block
# ----------------------------------------------------------------------
CLASSICAL_FOUNDATION:
  Main idea:
    - Mathematics supports modelling, prediction, optimization, measurement,
      and reasoning across sciences and industries.
  Career relevance:
    - engineering design, finance risk, operations planning,
      analytics, quality control, simulation.
# ----------------------------------------------------------------------
# 2) Civilisation-Grade Definition (locked)
# ----------------------------------------------------------------------
CIV_GRADE_DEFINITION:
  Career-math:
    - a modelling + decision loop under uncertainty:
      quantify → model → compute/approximate → interpret → decide → monitor → repair
  Reconnection:
    - math becomes career-aligned when learners repeatedly build models
      with assumptions, bounds, validation, and decision statements.
  Core Law:
    - stability when VerificationEffort >= ErrorPropagationRisk.
# ----------------------------------------------------------------------
# 3) Phase Map (P0–P3)
# ----------------------------------------------------------------------
PHASE_MAP:
  P0: "Procedure-only"
      - solves given equations; no modelling transfer
  P1: "Template modeller"
      - can model familiar contexts; breaks under variation
  P2: "Bounded modeller"
      - translates scenarios; uses units/bounds; validates results
  P3: "Decision-grade modeller"
      - frames model choices, stress-tests assumptions, communicates decisions
# ----------------------------------------------------------------------
# 4) Inequality Locks (corridor quality)
# ----------------------------------------------------------------------
INEQUALITY_LOCKS:
  L1: TranslationSuccess >= ContextVariation
  L2: UnitSense >= 0.95
  L3: SanityCheckRate >= 0.80
  L4: AssumptionVisibility >= 0.80
  L5: ToolValidation >= 0.70
# ----------------------------------------------------------------------
# 5) The Career-Math Loop (runnable corridor)
# ----------------------------------------------------------------------
CAREER_MATH_LOOP:
  Step1_Quantify:
    - define variables + units
    - define what must be measured/estimated
  Step2_Model:
    - choose simplest baseline model first
    - write constraints and assumptions (max 3)
    - identify objective (what we optimize)
  Step3_ComputeOrApproximate:
    - compute exactly if needed
    - otherwise estimate/bounds first, then refine
  Step4_Interpret:
    - translate result into meaning:
      "this means ___ in reality"
  Step5_Decide:
    - state decision rule:
      "If result > threshold, do ___; else do ___"
  Step6_Monitor:
    - track key metric over time
    - compare model vs reality
  Step7_Repair:
    - update assumptions/model based on error
    - document changes as SOP/checklist
# ----------------------------------------------------------------------
# 6) Validation Pack (minimum 2 checks every time)
# ----------------------------------------------------------------------
VALIDATION_PACK:
  V1_UnitsCheck:
    - units consistent; output unit makes sense
  V2_BoundsCheck:
    - output within plausible min/max
  Optional:
    V3_AlternateMethod:
      - compute via second approach or simpler approximation
    V4_BackOfEnvelope:
      - order-of-magnitude estimate
    V5_DataSanity:
      - outliers/measurement error check
# ----------------------------------------------------------------------
# 7) Topic→Career Engine Mapping (compressed)

      - constraints + relationships; pricing; budgeting; optimization basics
