The docs folder had drifted into a mixed-language contract: IMPLEMENTATION_SPEC.md was
entirely in English while the rest was Russian with English headings. Prose is now
Russian throughout; English is kept only where it is technically load-bearing (commands,
tool output, config keys, file/module/table names, tc handles) and for terms with no
settled Russian equivalent in this context (drift, reconcile, peer, namespace, handshake).
docs/README.md now states that contract explicitly.
Rewriting the spec surfaced several places where it described intent rather than the
code. Corrected against traffic_core/src:
- module layout: the spec showed traffic/ and firewall/ as directories with
model/inspect/apply submodules. They are single files, and sysctl_tuning.rs was
missing from the tree entirely.
- data model: Peer was documented as carrying public key, handshake and counters. It
carries only ipv4; runtime state lives in a separate PeerRuntime, and there is no
desired-state struct at all - it is derived inline from config plus sorted peers.
RuntimeTarget.netns_path is a String, not a PathBuf.
- interface detection: the spec listed a third step taking the first non-loopback
interface with an IPv4 address. No such fallback exists; detection bails with an
explicit error, which is safer and is now documented as deliberate.
- reconcile: the pseudo-flow folded firewall into reconcile_traffic. They are two
independent reconciles with separate locks.
- locking: only traffic.lock was documented. There are three locks, and
sysctl_tuning.lock has a 30s timeout rather than 10s. Stale-lock recovery via
/proc/<pid> was undocumented.
- sysctl_tuning: the module also manages /etc/modules-load.d/90-awg2-harness-bbr.conf
when BBR is active, and refuses to touch either managed file without its marker.
Both docs and the acceptance checklist claimed only the sysctl.d file was written.
- status contract: the documented output was outdated. All 15 printed sections are now
listed in the order status.rs emits them, including the degraded path when no container
is found, and the fact that the Network tuning block is printed between the System
service line and the container lines.
- swap: size was documented as a constant 2048 MB instead of swap.size_mb, and the
/etc/fstab.awg2-harness.bak backup was undocumented.
- apply/verify: the tolerated-error lists are now the actual closed sets from the code.
Acceptance checklist gained checks for the daemon startup failure policy (sysctl/swap
fatal, traffic/firewall not), lock contention and stale-lock recovery, degraded status,
the modules-load file, and the marker guard. The stale host wg requirement was dropped
from its host-tools item.
Every path, table, counter and log string quoted in the docs was verified to exist in
the source. cargo test --workspace: 110 + 4 passed.
has_ingress_redirect_to_ifb переведён на case-insensitive разбор и поддержку обоих вариантов: dev <ifb> и device <ifb>. Добавлены тесты на lowercase dev-формат и отрицательный кейс с другим ifb.
Также синхронизирован docs/ANTI_TORRENT.md: единая шкала threshold (100 default, 150 мягче, 200/250 permissive, 70 агрессивный), и антипример over 200 явно помечен как non-default/non-production.
Удалён Recommends: docker.io из control. Ужесточено предупреждение, что --install не является production-path. В .deb docs переведены на repo-like структуру (/usr/share/doc/awg2-harness/repo/...), чтобы не ломались относительные ссылки.
