The open ledgers behind keymail — email where, if the server is compromised, the attacker gets nothing. keymail is AI-written, and the way it's built is on the public record too: what it cost, who (and what) wrote it, every prompt behind it, and where it's going.
What it cost to build (exact AI tokens, banded CO₂e) and what it costs to run (the whole fleet, per day) — always with the honest range, never just the flattering end.
Who builds keymail — humans and AI models in one index, on the same metric.
Every prompt behind the codebase, published whole with secrets redacted and each redaction annotated. Searchable.
The honest plan for the road to V1 — what has to be true before we'd call it finished, and how far along each track is.
The story so far — the key moments of building keymail, each linked to the working session where it happened.
