SOURCE METHODOLOGY
How Little Headlines Perth checks change
The source hierarchy, coverage beats, importance gate and health labels behind the beta.
Last updated 8 October 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.
Coverage model
- Local records: council decisions, planning registers, consultations and works tied to a place.
- Perth-wide signals: construction supply, builder capacity, law and regulation, infrastructure, essential services, market and finance.
- Broad discovery runs across every beat so a story does not need to appear on an expected official page before it is noticed.
- Fixed source lanes ensure official, industry and reputable reporting routes are checked rather than relying on one publisher.
Importance gate
- Reach: how many people or projects could be affected.
- Consequence: likely time, money, safety or service impact.
- Actionability: whether a reader can usefully ask, check, submit or prepare.
- Status change: whether there is a genuinely new decision, deadline, disruption or milestone.
- Confidence: how direct and authoritative the evidence is. High-priority candidates are reviewed the same day.
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
Source reviewed means a dated editorial check is within its stated review period. Review overdue / unverified means no recent check is recorded. Building or publishing the website never refreshes a source’s check date.
Health is a retrieval signal, not a guarantee that the underlying authority has published every relevant record.
Coverage limit
No monitoring system can guarantee that every important development will be found. Twice-daily discovery now creates a human review queue and source failures are treated as alerts; stories are not automatically published.
Twenty historical suburb files are retained and many still need review. News email delivery remains paused. Other permanent pages remain noindex until their source coverage is substantive.
