- HostKeyPolicy trait: async, dyn-compatible (Arc<dyn> handle, the
alkcall injected-handle pattern) — decide(&self, &PresentedHostKey)
-> bool with host/port/fingerprint as the decision input
- Verdict type pinned to the russh 0.65 check_server_key shape:
bool is the trust decision; decline reasons stay with the policy
(declines are dispositions, not errors). Flagged for the wave-1 gate
- Built-in default RejectAll: fail-closed reject-all (russh's default,
kept); no accept-all option exists in the crate
- async-trait 0.1 added for the dyn-compatible async handle
(alkcall-precedented; tree-deduped). Flagged for the wave-1 gate
- Tests: default rejects; custom verdict honored; both through the dyn
handle; the whole presented context reaches the policy
