PRICE POSTURE
NSW price medians are parser-guarded official records.

Official sale records parsed from cached Bulk PSI ZIP files with parser guardrails for token sales, non-house zoning, and low-value strata component records

RENT POSTURE
Rent is using a state market dataset when available.

SERVICE POSTURE
Service coverage is matched locally, not inferred nationally.

Schools, transport, and hospitals are useful as presence signals, but they still have different source cadences.
