How the evidence was checked

extract.py checks every downloaded original and HTTP-header SHA-256, 82 selected source controls, the identities of 53 selected HTML tables, the ATO/APLNG exact-entity reconciliation, twelve months of country diesel inputs and five explicit calculations. Other narrative findings were checked against the cited pages; the script does not verify every sentence or independently validate source producers. Selected PDF tables were rendered and visually inspected: APLNG tax pages 5–6, aged care page 19 and NHSAC page 127.

observations.json contains typed values, observation period, population, geography, units, accounting basis, uncertainty note, exact source locator/URL and original hash. selected-tables.json preserves whole selected published tables as labelled strings; blanks, suppression flags and uncertainty columns are not silently converted to zeros or estimates. source-notes.json records publishers, visible release-date labels and unresolved publication metadata. All seventeen CTG workbooks are archived; selected land/sea/language cells are controlled, not every cell in every workbook.

Originals and full reading copies are local, git-ignored study material. Their collection does not grant permission to redistribute company reports, commercial property data or other third-party material. Source licensing and any unpublished statistical uncertainty still need review for a specific app destination. This is why no record is yet labelled ready for app adoption.

Batch 09 adds Origin’s issuer-authored FY2025 and FY2026 results lodged with SGX. verify_aplng.py reads the three pinned PDFs directly and checks 80 row controls, both cash reconciliations, the original FY2025 comparative, sales volumes, profit, debt and the FY2025 tax calculation. Run python3 verify_aplng.py for a read-only check of aplng-money-trail.json. --write regenerates that derived file; it does not change originals. The earlier 82 controls remain a separately counted baseline.

The annual reports close the dated project-debt and cash-distribution gaps left by failed Origin landing-page retrievals. They do not establish every lender identity or net public return. The final FY2026 cash-tax disclosure of A$1,414m differs from the preliminary A$1,410m; both are retained with their source boundaries. Four relevant FY2026 financial table pages were visually inspected.

From this directory, run python3 extract.py --check using the repository's research dependencies (lxml, openpyxl, pypdf). It expects the existing money-flow dossier at ../australia-money-flows; use --money-dossier PATH if located elsewhere. A failure stops the verification. It does not refresh sources or overwrite originals.

collect.py reuses scripts/research/source_library.py from the repository, rather than introducing another HTTP client. Its numbered batch files enumerate requested public URLs. Restoration is not automatic: a tracked checkout without the ignored originals will fail verification. For a new retrieval, copy collect.py and the numbered batches into a separate empty directory without this manifest, then run python3 collect.py batch-01.json --repository /path/to/repository and subsequent batches there. Compare the new body hashes with the pinned manifest; HTTP headers and live pages may differ. Keep the new capture separate and review revisions before adoption. Do not overwrite the pinned manifest and call that the same verification. Already-archived originals are checked and never overwritten by the collector.

Successful retries replace that source's previous failed status; the manifest is a final-resource record, not a complete HTTP-attempt history. In particular the PC assistance landing page required its canonical trailing-slash URL. The original failed route remains in its batch request.

“Facts/tables” counts only the selected reproducible controls. A zero does not imply the source was useless: it may supply methodology, qualitative findings or an archived lead. It also does not mean every source has been fully read.

Additional source records: origin-annual-2025-sgx and origin-annual-2026-sgx are pinned in manifest.json; their full locators and extracted controls are in aplng-money-trail.json.
