SOURCE METHODOLOGY
How Little Headlines Perth checks change
The source hierarchy, evidence gate, geography checks and health labels behind the beta.
Last updated 30 August 2026
Source hierarchy
- Primary: legislation, gazettes, court and tribunal records, regulator notices, council registers, agendas, minutes and government project pages.
- Authoritative data: official market, economic and administrative datasets.
- Reputable reporting: used for discovery, direct statements and context; attributed clearly.
- Social and reader tips: discovery leads only, never proof by themselves.
Publication gate
- Green: accessible primary evidence, neutral status and verified geography may publish after checks pass.
- Amber: credible reporting without accessible primary evidence is held for editorial review.
- Red: anonymous allegations, unsupported social posts or unverifiable claims are rejected from automatic publication.
What counts as a material change
- A new application, decision, hearing, formal response or official document.
- A changed deadline, status, condition or project milestone.
- A correction that changes the practical meaning of the record.
- Not a copied press release, repeated article or unchanged register entry.
Geography
Suburb, postcode and local government are stored separately. A postcode is never used alone to infer a council. Split-boundary suburbs require address-level qualification.
Source health
Healthy means the registered source was accessible during the last successful editorial check. Delayed means the source was accessible but appeared stale or incomplete. Unavailable means the source could not be retrieved during that check.
Health is a retrieval signal, not a guarantee that the underlying authority has published every relevant record.
Coverage limit
Monitoring is expanding and is not guaranteed to be complete. Twenty suburb pages currently meet the deep-monitoring standard and are submitted for indexing. Other permanent pages remain noindex until their source coverage is substantive.
