Background diagram: an animated engineering schematic. Commits flow from a station labeled YOUR AGENTS on the left into a vertical gate of 52 checks at center. Most pass through and exit right toward SHIP; roughly one in twelve turns red at the gate, loops down through a REPRODUCER station, and returns to re-enter the flow fixed. Each completed fix settles as a permanent pin in a growing CORPUS lattice below the gate. A thin stream rises to a SIGNATURES station at top right, where humans sign. The headline is lettered directly onto the drawing, with leader lines to its subjects, and a status strip along the bottom edge counts this session's simulated commits, findings, and pins — live counts from the animation, not business claims.

Your agents write. Your humans sign. Proof remembers.

LEGEND
A LIVING ASSURANCE SYSTEM FOR CODEBASES WHERE AGENTS NOW WRITE MOST OF THE CODE.
Every approval carries a human name.
Every finding ships with evidence and a fix prompt.
Every fix becomes a permanent pin in a corpus that never forgets.

52 checks. Exit ≠ 0 until the promises hold.

NOTE 1 — Every commit — engineer or agent — passes the same bar: formal requirements traced to code, annotations validated, coverage measured where it matters, hazards analyzed on the paths that hurt.

NOTE 2 — The gate does not negotiate and does not tire. Green means the promises hold. Anything else loops back as a finding — visible, reproducible, assigned.

REQUIREMENTS APPROVED — AND COUNTING · JSONPARSER, FIRST PUBLIC COMPONENT

NOTE 3 — Requirements written in FRETish — the structured requirements language from NASA's FRET program. Checked with the Kind2 model checker and the Z3 solver. MC/DC coverage across 11 languages. Hazard analysis where failure costs the most.

NOTE 4 — Defect classes close everywhere at once: one panic class traced to 8 sites, swept the same day. Closed classes stay closed — the corpus pins them; the gate re-proves them on every run.

Findings ship ready to fix.

NOTE 5 — Every finding carries a reproducer and an agent-ready fix prompt. Hand it to your engineers, paste it to your agents, or let our fix sprints take it — the same gate grades all three.

NOTE 6 — The loop closes when the gate says so, not when someone says done.

This drawing includes our errors.

NOTE 7 — During the jsonparser audit, a defect in Set() escaped with 100% MC/DC on the changed code — and was caught downstream. We published the postmortem, pinned the class, and tightened the gate. An assurance system you can trust is one that shows you where it failed.
