What Junctiq does, and what it does not claim.

What runs today

1. 01CaptureJunctiq fetches pages where companies state commitments and keeps the exact bytes it received, with a SHA-256 digest of them. The time recorded is when Junctiq fetched the page, not a date the publisher gave. Where robots rules or rights prevent storing a page, the record says what was withheld rather than implying the page was kept.
2. 02Re-checkPages are fetched again on a schedule. Every fetch is recorded as its own capture linked to the one before it, and says whether the bytes differ. Earlier captures are not overwritten.
3. 03TimestampThe digest of each capture is sent to independent RFC 3161 timestamp authorities. A returned token is that authority’s signed statement that the digest existed at that time. Junctiq verifies each token when it stores it.
4. 04LogEach capture is also entered in an append-only log that Junctiq operates, in which every entry commits to the ones before it. Nobody outside Junctiq can check that log yet — see “Not claimed” below.
5. 05ShowThe Vault lists captures with their digests and fetch times and answers its custody questions separately: does Junctiq hold the bytes, does the origin still serve them, does a public archive hold them. Where a question has not been asked, the page says unknown.

An exported evidence pack can be checked offline, against a receipt you obtained separately, at Verify. The result lists what it could not establish.

Not claimed

Each row is a statement Junctiq could make and does not, the reason, and the evidence that would change it.

• That pages like these commonly disappear from the web. — Not provenThe test that asks this was run once, on a news corpus, and did not show it. It has not been run on the pages of companies that make commitments.What would change it: A re-measure is scheduled for 2026-12-16, and a separate measurement on company pages is registered but has not run.
• That a particular page was deleted by its owner, or that only Junctiq holds it. — UnknownWhether a public archive holds a page is checked and recorded per capture, with a control. No such check has been recorded yet.What would change it: The origin no longer serving the page on two separate checks, and a dated archive check finding it absent.
• That Junctiq’s history can be checked independently. — Not measurableThe log exists, but its checkpoints are not published, so an outsider cannot yet confirm that earlier entries were not rewritten.What would change it: Signed checkpoints published daily, a month of them, and a consistency proof verified by someone other than Junctiq.
• What changed in a page, or whether the change matters. — Not measurableOnly two statements are licensed: the bytes differ, and the origin no longer serves the page. The detectors for text changes, additions and removals have not passed their own controls.What would change it: A detector that passes a control it can fail, with its false-positive rate measured per kind of document.
• Commitments extracted from pages, whether they held, and any record of a company’s reliability. — Not measurableExtraction and resolution against an outside source are not built. No commitment has been resolved.What would change it: Commitments with their resolution rule declared before the outcome, resolved against a source Junctiq does not control. Even then Junctiq will show counts, never a score.
• Statements about where a category is heading. — Not measurableNone has been published. Each would first have to contain something a model with web access cannot produce.What would change it: A statement that passes that comparison, published with every artifact behind it.
• That anyone relies on Junctiq. — UnknownNo evidence either way is offered here.What would change it: A customer paying for it.

What Junctiq will not do

Junctiq does not score or rate companies and does not estimate what any company will do. It records what was published and, later, what happened. What may be shown of a captured page is set by a retention rule, and the rule in force is provisional; where a page cannot lawfully be shown, the Vault shows its digest and fetch time and says what is withheld.
