BIND:
{PlaceID}::FIN-FAM-RWY::Z2::RunwayVisibilityBind::BIND::001
Parties: BudgetingSystem ↔ FamilyFinanceOperator
Goal: runway is visible, not guessed.
BIND:
{PlaceID}::FIN-FAM-RWY::Z2::ShockAbsorptionBind::BIND::002
Parties: EmergencyFundSystem ↔ EducationSpendProtection
Goal: prevent shocks from cutting education routines.
BIND:
{PlaceID}::FIN-FAM-RWY::Z2::DebtVolatilityBind::BIND::003
Parties: DebtLoadControl ↔ BudgetingSystem
Goal: debt servicing does not destroy buffers.
BIND:
{PlaceID}::FIN-FAM-RWY::Z2::EducationOSInterfaceBind::BIND::004
Parties: EducationSpendProtection ↔ EDU lanes (Z1 routines)
Goal: protect study time + resources during volatility.

SENSOR:
{PlaceID}::FIN-FAM-RWY::Z2::RunwayMonths::SENSOR::001
Measures: months of runway at current burn (implementation-defined).
SENSOR:
{PlaceID}::FIN-FAM-RWY::Z2::VolatilityIndex::SENSOR::002
Measures: income/expense variance; shock frequency proxy.
SENSOR:
{PlaceID}::FIN-FAM-RWY::Z2::DebtServiceRatio::SENSOR::003
Measures: debt servicing load relative to income.
SENSOR:
{PlaceID}::FIN-FAM-RWY::Z1::EducationSpendStability::SENSOR::004
Measures: continuity of essential learning spending.
SENSOR:
{PlaceID}::FIN-FAM-RWY::Z1::RoutineProtection::SENSOR::005
Measures: preserved study time and sleep stability during shocks.

THRESH:
{PlaceID}::FIN-FAM-RWY::Z2::Runway_T2::THRESH::001
Condition: runway becomes critically thin (implementation-defined band).
Action: ROUTE.FIN.001 (Stop-loss truncation of spend) + protect education routines.
THRESH:
{PlaceID}::FIN-FAM-RWY::Z2::Volatility_T2::THRESH::002
Condition: volatility rises sharply; repeated shocks.
Action: ROUTE.FIN.002 (Shock absorption + smoothing) + ROUTE.TRANS.001 (buffer thickening).

RouteID: ROUTE.FIN.001
Trigger: runway thin; debt pressure rising
Steps:
1) Freeze non-essential discretionary spending
2) Protect essentials + EducationSpendProtection
3) Reduce recurring commitments
4) Stabilise weekly cashflow
5) Rebuild emergency buffer
Verify:
- runway stabilises or increases
- volatility reduces

RouteID: ROUTE.FIN.002
Trigger: income instability or expense spikes
Steps:
1) Identify shock sources (variable costs, unstable income)
2) Install smoothing mechanisms (buffer rules, staged payments)
3) Increase emergency fund contributions
4) Reduce high-volatility liabilities
5) Protect Education routines as priority bind
Verify:
- shock frequency decreases
- routine stability improves

RouteID: ROUTE.FIN.003
Trigger: debt servicing causes routine collapse
Steps:
1) Map debt obligations and latency
2) Reduce penalty spirals (avoid compounding)
3) Renegotiate where possible (implementation-defined)
4) Install strict budget guardrails
5) Rebuild runway months
Verify:
- DebtServiceRatio improves
- routine buffers return

INTERFACE CLAIM:
Family runway instability increases shock frequency,
which collapses study routines and destroys stitching windows,
causing false competence and phase drops in learning.

RULE:
Protecting education is not “more tuition”.
It is preserving:
- sleep
- routine time
- calm bandwidth
- continuity of materials/support

FAILURE MODE TRACE:
runway thin + volatility high
→ family stress rises; routines break
→ learner sleep and practice time collapse
→ retention degrades; timed performance drops
→ false competence rises (signals without robustness)
→ exam failures cluster

Correct repair trace:
finance stop-loss truncation
→ shock absorption and smoothing
→ restore routines and buffers
→ education stitching routes regain effectiveness

CLAIMS (frozen):
- Family finance runway is a first-class buffer protecting Education OS.
- Volatility and thin runway destroy stitching windows and raise collapse risk.
- Sensors must track runway months, volatility, debt service, and education continuity.
- Correct repair is truncation + smoothing + buffer rebuilding, not panic escalation.
