Data trust

Coverage that is named, bounded and visible.

This register reports only the geography, time, evidence and refresh state we can declare for each product. It does not turn a source label into broader market coverage.

Data operations Closure queue Catalogue JSON

Declared scope

The coverage register is deliberately smaller than the catalogue.

A product appears here only where its published extent can be stated in four dimensions. An unlisted geography, a missing observation range or an unverified refresh is a boundary, not blank space to be filled with inference.

7 entries pass the ledger audit

7 products retain a material boundary in at least one dimension.

Five NEM regions are published within the NEM market boundary.

Each fixed edition names its own observation window; the ledger does not concatenate them into an unverified continuous history.

Evidence: covered

AEMO NEMWeb, AEMO WEM, Ember and Solar Analytica evidence ledgers

High confidence

Cross-source joins retain their individual source vintages.

export-constraint-regimes

Export Constraint Regimes

Open product

Geography: covered

Western Australia
WA rules are tied to exact connection-class and operator evidence.

Time: partial

release based

No aggregate date range declared

Evidence: covered

Australian electricity distributors and network operators

High confidence

A listed rule is evidence of a source condition, not a site-specific connection offer.

Updates: current

Monthly source check and material-rule change

Last checked: 30 July 2026
Next expected: 30 Aug 2026

Declared gaps

geographyOther Australian jurisdictions are outside this strict entity register until their state and network keys are added with evidence.
timeHistorical rule changes are not complete enough to support a continuous retrospective rule claim.

product-market-evidence

Product-Market Evidence

Open product

Geography: covered

Australia
Australian module, inverter and battery list evidence is represented at country level.

Time: partial

release based

No aggregate date range declared

Listings are source-edition records rather than a complete model-history archive.

Evidence: covered

Clean Energy Regulator and California Energy Commission

A listing proves source-list inclusion, not product quality, availability or suitability.

Updates: current

Weekly source checks; monthly review

Last checked: 31 July 2026
Next expected: 7 Aug 2026

Declared gaps

geographyCalifornia is not shown as a country-level claim; a verified jurisdiction key is required before it appears in this ledger.
timeThe ledger does not claim that a model absent from one edition was never listed in an earlier edition.

Last checked: 31 July 2026
Next expected: 7 Aug 2026

Declared gaps

timeThe ledger does not present shadow continuity as a verified historical operating record.

Open product

Geography: partial

Australia

Updates: not established

No scheduled refresh published

Last checked: 9 June 2026
Next expected: Not established

Declared gaps

geographyThe ledger does not imply coverage for unlisted cities, tariffs, utilities or countries in the 92-city panel.
evidenceThe panel is comparable only within its stated tariff and tax basis; it is not a retail procurement quote.
updateThere is no published next-refresh date for this fixed release.

Evidence boundary

A gap is an acquisition queue, not a negative claim.

Coverage is updated when a source, exact geography, observation window and review record can be joined. Product pages and the data-operations register retain the underlying source and release detail.
