1st Deployed Post-Quantum Immutable Edge-Relay, Flagship Whitepaper Release.
Most “post-quantum mail” posts are a slide. This one has a live isolate, a Gmail TLS header, and a 550 that still exists.
Most mail stacks still treat “Sent” as truth.
On 9 September 2026 we published the flagship technical record for a live Edge-Relay — not a mock, not a sector-numbered brochure.
What the video shows, and what the paper measures:
→ Isolate `ftu-immutable-relay` `0bde8d34`: Live Link in first Comments.
→ Binding-only health object. SHA-256 dispatch seal. D1 ledger offer.
→ Gmail hop on the same morning: **Standard encryption (TLS)** — that is the hop the inbox will attest.
→ Two dated failure specimens the product is built *not* to repeat: Hostinger → MailChannels **550 5.7.1**, and a wounded 7-day sending score after synthetic destinations.
Slash Turbo Ltd (No. 16090129) is putting Sovereign Cryptographic Communications in front of operators who already run the pipes — the mail platforms, the edge networks, the people who own bounce rate.
Read this before the comments do:
The live digest is SHA-256.
NIST PQC (ML-DSA / ML-KEM) is the named upgrade path.
A minted certificate is proof of **dispatch**, not proof the remote MX said yes.
GUI-only registrations are being forced through a 24-hour mailbox re-verify. CRM consent is a separate tick.
If you buy “quantum-immune mail” off a TAM slide, you will buy a banner.
If you buy a reconstructible preimage, a GET health object, and an Activity Log — watch the video, then open the flagship whitepaper.
Paper: FTU-SPEC_PostQuantum_Immutable_EdgeRelay_FLAGSHIP_WHITEPAPER.pdf & Live Relay: DOI, and links in first Comments.
CISO / counsel / deliverability: the limits section is the product.
