Both were in my wiring, not the design, and two reviewers found the first independently. 1. OUR STORE WAS TYPE-DOWNGRADABLE. The inline lookup filtered by key type first and could only answer match/mismatch/unknown, so a record of a DIFFERENT type for the same endpoint read as "unknown". A host learned on first contact — ed25519, since ssh2 proposes it first — and absent from known_hosts could then be impersonated by presenting RSA: both sources say unknown, so accept-and-remember, silently. That is exactly the downgrade D3 says the design cannot ship without, applied to the records we create ourselves. The store's own isTrusted already computed the right answer and had no production caller. Stored types now also feed the algorithm ordering, without which the guard is only half present. 2. WE KEYED ON THE ORCA LABEL, NOT THE DIALED HOST. "ssh -G" echoes its own argument back as its hostname field when no Host block matches, so for a manual target that field IS the Orca label — the one name D2 forbids keying on, and one ssh never wrote. We consulted no entries at all, so an impersonated host read as first contact. Now keys on the dialed host, which buildConnectConfig has already resolved through HostName, with HostKeyAlias still winning. That inverted an existing test rather than deleting it: "uses the resolved hostname, never the Orca label" encoded an assumption disproved against OpenSSH 10.2p1, so it is renamed and reversed with the reason recorded in the test. 3. NO READABLE SOURCE IS NOT FIRST CONTACT. Every known_hosts file failing to read was indistinguishable from "this host is unknown", so a changed key would be accepted the one time we could not check. The loader now reports how many files it could read, and zero readable sources with an empty store takes the strict path instead of recording trust. 4. A superseded attempt's rejection could replace the live attempt's error, and substituting a new Error drops ssh2's code, so a transient ECONNRESET would stop being classified as retryable. The rejection is now local to its attempt. 5. displayHost was the Orca label, so a mismatch could print "ssh-keygen -R <label>" — a remedy that removes nothing. Also adds the tests that would have caught 1 and 2, the stale-attempt denial, and IPv6 literals, which the design moved into scope and nothing covered. 1,469 SSH tests pass.
