LAN IP checked every 5s (cheap UDP socket call). Full upstream
re-detection runs every 30s as safety net, or immediately when
LAN IP changes. Reduces worst-case network switch recovery from
30s to 5s.

Expose current upstream address in /stats response. Dashboard footer
now shows "Upstream: x.x.x.x:53" — updates live when the network
watcher swaps the upstream.

When numa install is active, scutil --dns only returns 127.0.0.1.
Previously fell back to 9.9.9.9 (Quad9) which fails on networks
that block external DNS. Now reads DHCP-provided DNS from
ipconfig getpacket en0/en1 as intermediate fallback before Quad9.
Tested on a network that blocks 8.8.8.8, 9.9.9.9, 1.1.1.1 but
allows ISP DNS (213.154.124.25) — Numa now auto-detects and uses it.

Always detect network changes (LAN IP, upstream, peers) regardless
of upstream config. LAN IP is now tracked in ServerCtx and updated
every 30s — multicast announcements use the current IP instead of
the startup IP. Upstream re-detection still only runs when
auto-detected. Peer flush triggers on any network change.

Upstream DNS was resolved once at startup and never updated. Switching
Wi-Fi networks made all queries fail until restart.
Now spawns a background task (every 30s) that re-runs system DNS
discovery and swaps the upstream atomically if it changed. Also flushes
stale LAN peers from the old network on change.
Only activates when upstream is auto-detected (not explicitly configured).

On Windows, the not(macos/linux) cfg block is the only path, so
clippy flags the return as needless. Use expression form instead.

Gate version detection behind cfg(unix), fix unreachable Ok(()) after
return in trust_ca, use next_back() and is_some_and() per clippy.

Cross-platform paths: config_dir() uses %APPDATA%, data_dir() uses
%PROGRAMDATA% on Windows. TLS cert directory uses data_dir() instead
of hardcoded /usr/local/var/numa. Windows DNS discovery via ipconfig.
Fixed cfg gates from not(macos) to explicit linux to prevent Linux
code compiling on Windows. Added Windows target to CI and release
workflows with zip packaging.
System integration (numa install/service) not yet supported on Windows
— users run numa.exe manually.

Show whether each service is reachable from the network or bound to
localhost only. Dashboard displays green "LAN" or amber "local only"
badge next to each healthy service. Unified TCP check function,
concurrent health+LAN probes.

Replace IP-based self-announcement filtering with a per-process instance
ID (pid ^ timestamp) so multiple instances on the same host can discover
each other. Enable SO_REUSEPORT for multicast socket binding on Unix.
Add multicast address validation on configured group.

Numa instances on the same network auto-discover each other's .numa
services. No config, no cloud — just multicast on 239.255.70.78:5390.
- PeerStore with lazy expiry (90s timeout, 30s broadcast interval)
- DNS resolves remote .numa services to peer's LAN IP (not localhost)
- Proxy forwards to peer IP for remote services
- Graceful degradation if multicast bind fails

recv_from can never return more bytes than the buffer size — the kernel
truncates silently. == is the correct heuristic for detecting truncation.

- Set TC (truncation) bit when response exceeds 4096-byte buffer
instead of dropping the response silently. Clients can retry via TCP.
- Log when upstream response is truncated in forward.rs.
- Dockerfile: bump to Rust 1.88, include site/service files, use
alpine runtime instead of scratch, add cmake/perl for aws-lc-sys.
- Makefile deploy: platform-aware — codesign on macOS, systemctl on Linux.
- README: trim roadmap to near-term items only.
- Verified: Docker build + smoke test passes on Linux (Alpine musl).

security delete-certificate -c fails when multiple certs match.

macOS kills unsigned binaries, so numa service restart failed after
copying a new build. Added ad-hoc codesign to restart flow and a
make deploy target that handles the full build-copy-sign-restart cycle.

HTTP reverse proxy on port 80 lets developers use clean domain names
(frontend.numa, api.numa) instead of localhost:PORT. Includes WebSocket
upgrade support for HMR, TCP health checks, dashboard UI panel, and
REST API for service management. numa.numa is preconfigured for the
dashboard itself.

Kills the running process and lets launchd/systemd respawn it
with the updated binary. DNS stays configured throughout.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Default upstream auto-detected from system resolver (scutil/resolv.conf)
instead of hardcoding Google 8.8.8.8. Falls back to Quad9 (9.9.9.9).
- Single scutil --dns pass for both upstream detection and forwarding rules
- Linux: reads backup resolv.conf if current only has loopback
- Service start/stop now couples DNS config (install on start, uninstall on stop)
- Install script for one-line binary install from GitHub Releases
- GitHub Actions release workflow: builds for macOS/Linux x86_64/aarch64

Root cause: upstream resolvers return EDNS OPT records (type 41) in
the additional section. Our parser reads them as UNKNOWN, but write()
silently skips them — creating a header that claims N additional records
but a body with 0, producing FORMERR on the client side.
Fix: filter out UNKNOWN records before serialization and adjust header
counts to match. Also increase BytePacketBuffer from 512 to 4096 bytes
to handle modern DNS responses with many records.

GET /blocking/check/{domain} — returns whether a domain is blocked,
the reason (exact match, parent domain, allowlist, disabled), and
the matching rule. Dashboard sidebar has a "Check Domain" search
box with inline results and one-click allow button.

- Detect systemd-resolved: use drop-in config instead of overwriting
/etc/resolv.conf (which gets regenerated)
- Warn if /etc/resolv.conf is a symlink (NetworkManager, etc.)
- Fix TOCTOU: attempt copy/remove directly, handle NotFound
- Remove side-effect from backup_path_linux (no eager mkdir)
- Fix macOS $HOME fallback: /var/root instead of /tmp
- Log warnings on launchctl/systemctl failures instead of silencing
- Delete plist before unloading (prevents zombie restarts)
- Extract ensure_binary_installed helper on Linux

Linux:
- numa install: backs up /etc/resolv.conf, sets nameserver to 127.0.0.1
- numa uninstall: restores original /etc/resolv.conf from backup
- numa service start: installs systemd unit, enables + starts
- numa service stop: stops, disables, removes unit file
- numa service status: shows systemctl status
macOS: launchd plist (already working)
Both platforms: Restart=always / KeepAlive=true for crash recovery.

numa install — saves current DNS, sets all network services to 127.0.0.1
numa uninstall — restores original DNS from ~/.numa/original-dns.json
numa help — shows usage
macOS: uses networksetup to enumerate services and set/restore DNS.
Linux: stubs with instructions for manual setup.
