- lastconn keeps a most-recent-first ring (cap 8, backward compatible); reconnect tries the ring before any scan - MASQUE candidates rotate ports in waves (pool hosts no longer primary-port-only), anchors keep lead position + full tail coverage - verify_one runs a cheap Initial/SYN pre-filter (non-ironclad) before the full crypto handshake; silent hosts die in ~1 RTT - AETHER_PROBE_JITTER_MS paces probe starts (default 0 = unchanged)

Bring the custom core fork onto the production v1.9.0 baseline used by Aether-GUI and include the bounded scanner improvements from upstream PR CluvexStudio#103. Core version remains independent from the GUI.

What
Four bounded improvements to the endpoint scanners. No CLI changes, fully backward compatible.
1. Recent-winners ring (
lastconn.rs,lib.rs)LastConnectionnow also stores a most-recent-first ring of working endpoints (recent, cap 8,#[serde(default)]— old files load unchanged). Bothrun_masqueandrun_wireguardtry the ring newest-first before any sweep, so a reconnect usually completes in seconds instead of falling into a full scan after a single stale cached peer.2. MASQUE port waves (
prober.rs::build_candidates)Previously the pool of sampled CIDR hosts was only probed on the primary port (443); the multi-port loop covered the 8 seeds only. The WG scanner already rotated ports for its pool (
ports[(idx + wave) % port_count]), so this brings MASQUE to the same shape: wave 0 rotates ports across the ordered list, wave 1 covers each address once more on its next rotated port. Anchors keep their lead positions plus full multi-port tail coverage, as before. Tested:anchors_still_lead_in_position_with_spread_ports,pool_hosts_get_a_rotated_alternate_port_up_front,candidate_list_has_no_duplicates.3. Cheap reachability pre-filter (
prober.rs::verify_one)Non-ironclad probes send one bare QUIC Initial (TCP SYN when the HTTP/2 transport is enabled) and skip the full crypto handshake when the host stays silent. A real MASQUE edge must answer an Initial (RFC 9000), and the codebase's own range-characterization test already treats any Initial reply as liveness. Ironclad mode is untouched (no pre-filter, full HTTP request per candidate). Budget:
prefilter_timeout= half the per-probe timeout, clamped to 2–5 s.4.
AETHER_PROBE_JITTER_MSOptional max per-probe random start delay (default 0 = unchanged behavior) to smooth scan bursts on networks that rate-limit scanners. Documented in
--help.Not changed
Strategy deadlines, concurrency caps, CIDR/seed lists, candidate head ordering for the scan log, ironclad flow, file formats (additive serde fields only).
