CII-BUILD Batch 01 — Climate context intake and engineering-risk translation

[simon947161]

Parent

Issue #3 — CII-BUILD Phase 0.

Objective

Define the controlled handoff from ClimateOS evidence into BuildingOS without allowing a global climate signal to become a direct site, compliance or damage conclusion.

Deliverables

• docs/integration/CLIMATEOS_CLIMATE_CONTEXT_INTAKE_CONTRACT_V0_1.md
• docs/risk/CLIMATE_DRIVER_TO_BUILDING_RISK_TRANSLATION_V0_1.md
• static Australian example
• China placeholder-jurisdiction example with no fabricated legal or compliance result

Intake objects

• climate driver state
• regional climate tendency
• local hazard candidate
• observed event evidence
• spatial boundary and scale
• observation/forecast window
• confidence and uncertainty
• provider/model provenance
• evidence passport reference

Translation chain

climate driver → regional tendency → environmental condition → site hazard → building exposure → vulnerability → engineering behaviour → observed evidence

Initial risk pathways

• drought and reactive-soil movement
• extreme rainfall and flooding
• heat
• bushfire weather
• wind and tropical-cyclone exposure
• water-supply stress

Guardrails

• BuildingOS does not diagnose ENSO, IOD, SAM or cyclone tracks.
• No climate index directly triggers a compliance conclusion.
• No inferred building damage without observed evidence.
• Jurisdiction-specific rules remain separate from physical-risk translation.

Acceptance criteria

• Every stage is represented as a separate object or explicit relationship.
• Provenance, uncertainty, spatial scale and validity period survive the handoff.
• Missing site evidence produces an unresolved/conditional state, not a conclusion.
• Contract remains provider-neutral and does not hard-code MAZU or any other source.

Execution mode

Static documentation, schemas, examples and tests only. Draft PR; do not merge without Founder review.
