BLOCK_01_QUICK_ANSWER (AboveTheFold; PAA-ready)
Answer_45_70w:
  Mathematicians define mathematics through different “lenses”: patterns, structure, proof, language, abstraction, and understanding. These are not contradictions; they are different compressions of the same engine. Use the lens that matches your goal: learning (understanding), rigor (proof), power (abstraction), or application (modeling). This page gives a curated set of definitions with a “how to use” map.
Bullets:
  - Same engine, different compressions (lenses)
  - Pick lens by purpose (learn / prove / apply / invent)
  - Lens -> training plan (what to practice)

============================================================

BLOCK_02_USAGE_INSTRUCTIONS (How to use this page)
Rule:
  Choose ONE lens as your “primary lens” for 2 weeks, then rotate.
  Do NOT mix lenses mid-problem under time pressure.
Mapping:
  - If you panic (P0): pick UNDERSTANDING lens + Meaning-Lock drills
  - If you copy steps (P1): pick PROOF lens + “first illegal step” drills
  - If you can’t start: pick REPRESENTATION lens + diagram/encoding drills
  - If you solve but can’t explain: pick LANGUAGE lens + define/rewrite drills

BLOCK_04_LENS_MAP -> AVOO ROLES (why definitions differ)

AVOO_MAPPING:
  Operator_Lens:
    - "math = procedures that must run correctly"
    - outputs: correct execution trace
  Oracle_Lens:
    - "math = validity preservation (proof + counterexample)"
    - outputs: audit, first illegal step, assumption scan
  Visionary_Lens:
    - "math = representation + modeling language"
    - outputs: map reality -> variables + constraints + objective
  Architect_Lens:
    - "math = corridor generator (new representations/invariants/reductions)"
    - outputs: new reusable method family with validity proof

============================================================

BOX_CIVOS_LENS (Why this page is a CivOS component)
CivOSClaim:
  Definitions are "meaning locks."
  Civilisation collapses when meanings drift under load.
Mechanism:
  - shared definitions -> shared coordination -> scalable systems
  - definition drift -> model drift -> decision drift -> error cascades
Bridge:
  - Symmetry_A: enough people share math meaning -> projection unlock
  - Symmetry_B: math expands objects while preserving validity
SeeAlso:
  - /symmetry-of-mathematics-genesis-selfie/

============================================================

BOX_NEG_VOID (Google-style: what goes wrong)
NegativeVoid:
  FailureModes:
    - quote-shopping (collecting definitions without using them)
    - mixing lenses mid-problem -> confusion under time
    - memorizing slogans instead of building skill loops
  Outcome:
    - P1 template dependence
    - P2 never forms (transfer collapses)
FailureTrace:
  no meaning lock -> wrong model -> wrong step -> panic -> avoidance -> capability attrition

============================================================

SENSOR_PANEL_DEFINITIONS (FenceOS-lite)
Sensors:
  SML: Symbol-Meaning Lock (can you define your symbols?)
  LensStability: do you keep one lens per session?
  ExplainRate: can you explain steps in plain language?
  AuditHabit: do you check first illegal step?
Thresholds:
  Fence_P0_Definitions:
    if (SML low) -> TRUNCATE new problems -> do meaning-lock drills
  Fence_P1_Definitions:
    if (ExplainRate low) -> switch to Understanding + Proof lens drills
  Promote_P2_Definitions:
    if (ExplainRate high) AND (AuditHabit present) -> allow timed mixed sets

FAQ_PACK (PAA-ready)

Q1: What is the best definition of mathematics?
A_45_70w:
  There isn’t one “best” definition—mathematicians use different lenses: patterns, structure, proof, language, and understanding. The best definition is the one that fits your goal right now. If you are learning, use the “understanding” lens. If you are proving, use the “implication/proof” lens. If you are applying, use the “modeling language” lens.
Bullets:
  - Learning: understanding lens
  - Rigor: proof/implication lens
  - Application: modeling/representation lens
SeeAlso: /how-mathematics-works/

Q2: Why do mathematicians define mathematics differently?
A_40_70w:
  Because mathematics has one engine but many entry points. Some compress it as “patterns” (what repeats), others as “proof” (why it’s true), others as “language” (how it transfers across contexts), and others as “understanding” (what good math produces). These are compatible views of the same validity-preserving system.
Bullets:
  - Same engine, different compression
  - Different role focus (Operator/Oracle/Visionary/Architect)
  - Different training emphasis
