Two product decisions, both taken deliberately after a review priced their blast radius, and both moving us from stricter-than-ssh to matching it. CERTIFICATE-AUTHORITY HOSTS NO LONGER FAIL. The point of an SSH CA is that the client holds ONE line — very often `@cert-authority *` — instead of per-host entries. That line matches every candidate, so for a Teleport / Vault-SSH / Smallstep / in-house-CA user EVERY target failed, not just CA-signed ones, including on-demand runtime VMs, and StrictHostKeyChecking=no did not help. The documented escape was an environment variable, which an Electron app launched from the Dock or Start Menu never sees. Meanwhile OpenSSH, verified live, treats a CA-covered host presenting a plain key as first contact and connects: ssh2 cannot validate certificates at all, so refusing bought nothing ssh was not already giving up. The residual risk is real and accepted — for a CA-protected host we take a plain key we cannot tie to the CA — and the ca-only outcome is carried through the decision so it stays visible in the log. AN UNREADABLE known_hosts NO LONGER REFUSES EVERYTHING. Any non-ENOENT read error on any configured file rejected every unknown host, with a message blaming the system SSH configuration, which was not what happened. The common trigger is not exotic: a Windows OneDrive Known Folder Move placeholder while offline fails with a cloud-file error, not ENOENT. It was also asymmetric with our own store, which degrades an unreadable file to "nothing trusted" and connects. We now connect as ssh does — it warns and treats the host as unknown — but record NOTHING, so a first contact we could not check never becomes durable trust. That second half is the reason the first is acceptable, so it is pinned end to end with the store actually bound. Which meant splitting verificationSourcesIncomplete back apart. It had been one flag for two claims that now diverge: "a site policy may exist that we cannot read" still refuses, "a file we could not open may contradict this" does not. Merging them was what made the second inherit a strictness only the first justified. Both still lose to evidence we DID read: a mismatch, a revoked key, or an explicit StrictHostKeyChecking still refuse in either state. pnpm lint clean; 1,549 SSH tests pass.
