- Add per-src QPS counter (_qps_window) with flood_suspect event at ≥50 qps/10s;
one event per src per 30s cooldown, does not suppress baseline query events.
- Add tracking_evicted telemetry every 100 LRU evictions so IP-rotation evasion
of _txt_times/_qps_window/_recon_window is observable, not silent.
- Shared _track_lru helper consolidates LRU touch + eviction signalling across
all three bounded OrderedDicts.
- Add TYPE_AAAA=28 support: _fake_ipv6() returns deterministic ULA (fd::/8)
addresses for in-zone names; extra_records parser now accepts and validates
AAAA entries via socket.inet_pton.
- Add per-src recon-burst aggregation (_recon_window): fingerprint_probe +
zone_transfer + amp_probe are tracked per source in a 60s window; recon_burst
fires when ≥2 distinct signal types seen, once per src per 120s cooldown.
- 47 tests passing (19 new across TestAAAARecords, TestFloodDetection, TestReconBurst).
Python asyncio DNS server on UDP+TCP/53 masquerading as BIND 9.x.
Emits four event_type values: query, fingerprint_probe (version.bind /
hostname.bind / id.server CHAOS), zone_transfer (AXFR/IXFR, always
REFUSED), amp_probe (qtype=ANY or EDNS udp_size>1232), and
tunneling_suspect (long high-entropy labels or rapid TXT burst).
Zone persona is generated per-decky from instance_seed (domain name,
SOA serial, NS, A, MX, TXT SPF); overridable via config_schema.
Three zone modes: auth (default), recursive, open (sinkhole).
