The actual fix. ssh-connection's verifier recorded a fingerprint and returned
true, so every ssh2 connection accepted every host key — no known_hosts consult,
no change detection. It now consults the user's known_hosts plus our own store
and refuses a changed, revoked or unverifiable key.
Phase 1 by design: no dialog. Unknown hosts are accepted and recorded
(accept-new semantics), because startup restore opens every previously-active
target at once, ephemeral VM targets present a new key each launch, and
paired-web connects run on the host desktop where a prompt would appear on
someone else's screen. The MITM defence lands now; the prompt is Phase 2.
Also sets algorithms.serverHostKey to lead with the types already known for the
host. Without it the type-scoped matching is a downgrade — an attacker who cannot
forge the key on file just presents another type and turns a hard failure into
first contact. Verified from ssh2's kex.js that the client list decides.
Denial replaces ssh2's generic handshake error with the specific reason, because
the reconnect ladder cannot distinguish a generic failure from a transient fault
and would retry forever against a decision that will never change.
An unreadable trust store degrades to known_hosts only rather than failing the
connect: a changed key is still refused, and a host trusted only by us falls back
to first contact and is re-recorded, reaching the same decision.
The ssh2 mock now uses the callback form and aborts the handshake on denial. As
written it called hostVerifier(key) with one argument and ignored the result, so
it would have passed against a verifier that never decides — flagged in the
design as a mock that had to change, not a test to quietly rewrite. Two new tests
pin the wiring rather than the module: an unidentifiable blob is refused, and a
well-formed key is accepted.
Note for review: commit 2d2a0880ba unintentionally swept in two modules built
concurrently (ssh-known-hosts-source, ssh-host-key-store) because I staged with
'git add -A'; its message describes only the verifier. Both are covered by their
own tests, but the attribution in that commit is wrong.
1461 SSH tests pass.
