What assumptions had to be true before an experimental submersible could be relied upon for repeated human dives to Titanic depth?

Public PDF status
The research phase is approved. Final public dossier production, publication-stage fairness controls, specialist sign-off where required and final publication QC remain separate release gates.
The website will not substitute a preview or controlled draft and label it as the final public PDF.
Decision question
What assumptions had to be true before an experimental submersible could be relied upon for repeated human dives to Titanic depth?
This is demonstration work. Aperture Research Works did not act for the subject or another party in this matter. The purpose is to let a prospective buyer inspect the work product and judge the evidentiary discipline for themselves.
Decision-safe result
Official investigations support serious deficiencies in pressure-vessel validation, lifecycle assurance, monitoring interpretation and independent challenge.
What the buyer can inspect
Independent challenge of technical assurance, warnings, testing, monitoring and governance.
The public material provides enough evidence, reasoning, limitations and reliance context to assess the output. Detailed non-public methodology, working material and controls are not published.
What this demonstrates
Independent challenge of technical assurance, warnings, testing, monitoring and governance.

You do not need to diagnose the product first. Start with the claim, counterparty, financial record, technical assurance or decision you do not want to trust blindly.
