Run complete-product acceptance, human validation, and release audit

[EcstaceeLOR]

Goal

Apply a binary finished-product gate before Signum is called complete.

Scope

• Review every route and state against the route/UX contract on mobile, tablet, desktop, keyboard, screen reader, and embedded host.
• Complete five first-time-player sessions plus an independent non-implementer audit.
• Verify production Vercel deep links, manifest, widget, iframe behavior, source access, metadata, and rollback.
• Record production Chain deployment/registration separately from standalone availability.
• Resolve every critical/high finding and explicitly accept lower-severity debt.

Acceptance criteria

• Every child issue in the complete-product epic is closed with evidence.
• Five human sessions meet comprehension/time criteria and findings are documented without personal data.
• Independent reviewer signs the tested commit and production URL.
• No placeholder, dead control, fake data, broken route, contract/RTP mismatch, or critical/high finding remains.
• Release record identifies exact commit, CI run, deployment, URL, and production Chain address when real wagering is enabled.

Automated acceptance completed and merged in PR #106.

Evidence:

• CI run 36189905016: quality, standalone route matrix, and Chain simulator all pass
• Vercel preview deployment passes
• production Vercel root/deep-link/manifest/widget/iframe smoke passes
• Pages SPA deep-link fallback added
• exact evidence and unresolved gates recorded in docs/RELEASE_AUDIT.md

Issue remains open only for its explicit external acceptance criteria: five real first-time-player sessions (#27), independent non-implementer sign-off (#33), and production Chain deployment/registration before real wagering (#23).
