f264cea5b4 feat: per-suffix conditional forwarding rules in numa.toml (#82)
Adds a `[[forwarding]]` config section so users can explicitly route
domain suffixes to specific upstreams. Config-declared rules take
precedence over auto-discovered rules (macOS scutil, Linux search
domains) via first-match semantics.

Example — the reporter's reverse-DNS case:

  [[forwarding]]
  suffix = "168.192.in-addr.arpa"
  upstream = "100.90.1.63:5361"

Bare IPs default to port 53. IPv6 is supported via
parse_upstream_addr. ForwardingRule::new() constructor replaces
direct struct-literal construction, and make_rule() now delegates
to parse_upstream_addr to fix a latent IPv6 parsing bug.

22bebb85a0 fix: config path advisory ignores XDG file on interactive root (#81) (#83)
Port-53 and TLS-data-dir advisories told users to create
~/.config/numa/numa.toml, but config_dir() routed root to
/var/lib/numa/ and load_config never consulted the XDG path, so
the file the user created was silently ignored.

New suggested_config_path() helper prefers $HOME/.config/numa/
when HOME is set (and isn't "/" or empty), with config_dir() as
lazy fallback. Used by both advisories and by load_config as an
additional candidate, so the advised path is the path numa
actually reads. Runtime state (services.json, TLS CA) stays in
FHS — config_dir()/data_dir() are intentionally unchanged to
keep continuity with the installed daemon.

End-to-end replication + regression check in
tests/docker/issue-81.sh: four scenarios (replication and
existing-install, each against main and fix), all matching
expectations.

f556b60ce4 fix: suppress recursive hint in install when already configured (#71)
`sudo numa install` unconditionally printed the "Want full DNS
sovereignty?" hint even when numa.toml already has mode = "recursive".
Now loads the config first and skips the message if recursive is
already set.

643d6b01e1 fix(linux): consult resolvectl when resolv.conf only shows the stub (#52)
On modern Arch / Ubuntu 22.04+ / Fedora desktops, NetworkManager +
systemd-resolved symlink /etc/resolv.conf to stub-resolv.conf, which
contains only:

  nameserver 127.0.0.53

The real upstream servers (router, ISP, configured DoT providers) live
inside systemd-resolved's per-link state, exposed via 'resolvectl status'.

discover_linux() was parsing /etc/resolv.conf, correctly filtering the
stub address, and then falling through to the Quad9 DoH fallback because
detect_dhcp_dns() is macOS-only on Linux. Net effect: on a large chunk of
Linux installs, numa silently defaulted to Quad9 instead of the user's
actual DNS — visible in Casey's AUR test banner (#33) as
'Upstream https://9.9.9.9/dns-query' despite his machine having working
router DNS the entire time.

resolvectl_dns_server() already exists — it was introduced for cloud VPC
forwarding-rule discovery and knows how to ask systemd-resolved for the
real active DNS server. This commit wires it into the default-upstream
fallback chain, between the primary resolv.conf parse and the
~/.numa/original-resolv.conf backup.

fab8b698d8 fix: human-readable advisories for TLS data_dir + port-53 EACCES (#48)
* fix: human-readable advisory when TLS data_dir is not writable

When numa runs as non-root on a system with a privileged default
data_dir (e.g. /usr/local/var/numa on macOS), TLS CA setup fails with
a raw "Permission denied (os error 13)" and HTTPS proxy is silently
disabled. The user sees a cryptic warning with no path forward.

Detect std::io::ErrorKind::PermissionDenied on the tls error, print a
diagnostic naming the data_dir and offering two fixes (install as
system resolver, or point data_dir at a writable path), and keep the
graceful-degradation behavior — DNS resolution and plain-HTTP proxy
continue to work without HTTPS.

All other TLS setup errors fall through to the existing log::warn!.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: port-53 advisory also handles EACCES (non-root privileged bind)

The original port-53 match arm only caught EADDRINUSE, so a fresh
non-root user on macOS/Linux hitting EACCES when trying to bind a
privileged port saw the raw OS error instead of the advisory.

Collapse the scoping helper and the advisory into a single
`try_port53_advisory(bind_addr, &io::Error) -> Option<String>` that
returns the formatted diagnostic when both the port is 53 and the
error kind is one we can speak to (AddrInUse or PermissionDenied),
and `None` otherwise. The two failure modes share one body with a
cause-sentence variant — no duplicated fix text.

Caller becomes a plain if-let: no match guard, no separate is_port_53
helper exposed on the public API. is_port_53 goes back to private.

Unit tests cover all branches: AddrInUse, PermissionDenied, non-53
bind_addr, unrelated ErrorKind, and malformed bind_addr.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* refactor: move TLS error classification into tls module

main.rs no longer downcasts a boxed error to figure out whether it's
a permission-denied case. tls::try_data_dir_advisory(&err, &dir)
encapsulates the downcast + kind match and returns Some(advisory) or
None, mirroring system_dns::try_port53_advisory. main.rs becomes a
plain if-let, symmetric with the port-53 path.

Trim the docstrings on both advisory functions: they were narrating
the implementation (errno mapping) instead of stating the contract.

Add unit tests for try_data_dir_advisory covering PermissionDenied,
other io::ErrorKind, and non-io errors.

a6f23a5ddb fix: advisory + exit(1) when port 53 is already in use (#45) (#47)
* fix: advisory + exit(1) when port 53 is already in use (#45)

Detect AddrInUse on bind, print a human-readable diagnostic explaining
systemd-resolved / Dnscache as the likely cause and offer two concrete
fixes (sudo numa install, or bind_addr on a non-privileged port), then
exit(1) instead of surfacing a raw OS error.

Adds tests/docker/smoke-port53.sh: end-to-end Docker test that
pre-binds port 53 with a Python UDP socket and asserts the advisory +
exit code.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* refactor: collapse port53 advisory to single flat path

The per-platform cause sentences were cosmetic — they didn't change
the user's actions (install, or bind_addr on a non-privileged port),
but they introduced duplicated "another process..." strings, a
dead-from-CI branch (is_systemd_resolved_active() == true is never
reached by any test), and a pub visibility bump on
is_systemd_resolved_active for a single caller.

Replace with one flat format! whose cause line mentions both
systemd-resolved and the Windows DNS Client inline. The existing
smoke test now exercises 100% of the function.

is_systemd_resolved_active reverts to private.

bf5565ac26 fix: macOS use launchctl bootout/bootstrap instead of deprecated load (#42)
The deprecated `launchctl load -w` returns exit code 0 even when it
cannot actually reload a service whose label is already in launchd's
in-memory state. It prints `Load failed: 5: Input/output error` to
stderr but exits 0, so the install path interprets it as success and
continues — silently leaving the running daemon on whatever binary
was first loaded, even though the on-disk plist now points elsewhere.

The consequence: every macOS user running `brew upgrade numa` rewrites
the plist to point at the new binary, but launchctl never actually
loads it. They think they upgraded; they're still running the old
version. Neither #41 (cross-platform CA trust) nor #40 (self-referential
backup) would actually take effect for them until they manually run:

  sudo launchctl bootout system /Library/LaunchDaemons/com.numa.dns.plist
  sudo launchctl bootstrap system /Library/LaunchDaemons/com.numa.dns.plist

The fix uses the modern API symmetrically across all three call sites:

- install_service_macos: bootout (best-effort cleanup, no-op on first
  install) → bootstrap → wait for readiness → configure DNS
- install_service_macos rollback path: bootout instead of `unload`
- uninstall_service_macos: bootout BEFORE remove_file (the modern API
  needs the plist file path as the specifier; doing it after remove
  would leave the service in memory until reboot)

No new tests — this is a shell-call substitution with no logic to
unit-test. Verified manually on macOS: `sudo numa install` no longer
prints `Load failed`, and the daemon is correctly running the binary
the plist points at.

679b346246 fix: prevent self-referential DNS backup on re-install (#40)
* fix: prevent self-referential DNS backup on re-install

The install flow previously captured current system DNS servers
verbatim into the backup file. If numa was already installed, current
DNS was 127.0.0.1, so the "backup" recorded 127.0.0.1 as the "original"
— making a subsequent uninstall a no-op self-reference.

Reproduced 2026-04-08 during v0.10.0 brew dogfood: after
`sudo numa uninstall; sudo /opt/homebrew/bin/numa install`,
`sudo numa uninstall` printed `restored DNS for "Wi-Fi" -> 127.0.0.1`
because the brew binary's install step had overwritten the backup with
the already-stub state.

Fix (all three platforms):
- macOS/Windows: if the existing backup already contains at least one
  non-loopback/non-stub upstream, preserve it as-is. If writing a fresh
  backup, filter loopback/stub addresses first so a capture from
  already-numa-managed state isn't self-referential.
- Linux (resolv.conf fallback path): detect numa-managed or all-loopback
  resolv.conf content and skip the file copy in that case; preserve an
  existing useful backup rather than overwriting it. systemd-resolved
  path is unaffected (uses a drop-in, no backup file).

Adds three unit tests for the predicates: macOS HashMap detection,
Windows interface filter, and resolv.conf parsing (real upstream,
self-referential, numa-marker, systemd stub, mixed).

* refactor: share iter_nameservers helper and reuse resolv.conf content

Post-review simplifications on the stale-backup fix:

- Extract iter_nameservers(&str) helper used by both parse_resolv_conf
  and resolv_conf_has_real_upstream. Eliminates the duplicated
  line-by-line nameserver parsing (findings from reuse review).
- install_linux: reuse the already-read resolv.conf content via
  std::fs::write instead of a second read via std::fs::copy.
- install_macos / install_windows: flatten the conditional eprintln
  pattern — always print a blank line, conditionally print the save
  message. Equivalent output, less branching.

Net −12 lines. All 130 tests still pass, clippy clean.

* fix: drop redundant trim before split_whitespace

CI caught `clippy::trim_split_whitespace` on Rust 1.94: `split_whitespace()`
already skips leading/trailing whitespace, so `.trim()` first is redundant.

* refactor: extract load_backup helper

Remove duplicated read+deserialize boilerplate shared by install_macos
and install_windows. The two call sites each had an identical 4-line
chain of read_to_string().ok().and_then(serde_json::from_str).ok() —
collapse into a single generic helper load_backup<T>().

* Revert "refactor: extract load_backup helper"

This reverts commit a54fb99428.

* test: drop windows_backup_filters_loopback

The test inlined the 3-line filter block from install_windows rather
than calling a production helper, so it was testing stdlib Vec::retain
+ is_loopback_or_stub — both already covered elsewhere. Deleting it
removes a test that would silently pass even if install_windows stopped
filtering altogether.

The predicate logic for macOS-shaped backups stays covered by
macos_backup_real_upstream_detection (same inner Vec<String> type).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: add windows_backup_filters_loopback unit test

The PR description mentioned this test but it was missing from the
diff, leaving backup_has_real_upstream_windows untested. Mirrors the
shape of macos_backup_real_upstream_detection: empty map → false,
all-loopback (127.0.0.1, ::1, 0.0.0.0) → false, one real entry
alongside loopback → true.

Also relax the cfg gate on backup_has_real_upstream_windows from
cfg(windows) to cfg(any(windows, test)) so the test compiles
cross-platform, matching how backup_has_real_upstream_macos and
the resolv_conf helpers are gated.

039254280b fix: cross-platform CA trust (Arch/Fedora + Windows) (#41)
* fix: cross-platform CA trust (Arch/Fedora + Windows)

Closes #35.

trust_ca_linux now detects which trust store the distro ships and
runs the matching refresh command, instead of hardcoding Debian's
update-ca-certificates. Detection walks a const table in priority
order, picking the first whose anchor dir exists:

  - debian: /usr/local/share/ca-certificates  (update-ca-certificates)
  - pki:    /etc/pki/ca-trust/source/anchors  (update-ca-trust extract)
  - p11kit: /etc/ca-certificates/trust-source/anchors (trust extract-compat)

Falls back with a clear error listing every backend tried.

Adds Windows support via certutil -addstore Root / -delstore Root,
removing the silent CA-trust gap on numa install (previously the
service installed but the trust step quietly errored, leaving every
HTTPS .numa request throwing browser warnings).

Refactor: trust_ca and untrust_ca are now thin dispatchers calling
per-platform helpers. CA_COMMON_NAME and CA_FILE_NAME are centralized
in tls.rs and reused from system_dns.rs and api.rs. untrust_ca_linux
no longer pre-checks file existence (TOCTOU) and skips the refresh
when no file was actually removed.

Test: tests/docker/install-trust.sh runs the install/uninstall
contract against debian:stable, fedora:latest, and archlinux:latest
in containers, asserting the cert lands in (and is removed from)
the system bundle. All three pass locally.

README notes the Firefox/NSS limitation (separate trust store).

* test: macOS CA trust contract test (manual)

Adds tests/manual/install-trust-macos.sh — a sudo bash script that
mirrors trust_ca_macos / untrust_ca_macos against a fixture cert with
a unique CN. Designed to coexist with a running production numa:

- Refuses to run if a real "Numa Local CA" is already in System.keychain
  (fail-closed protection for dogfood installs)
- Uses a unique CN ("Numa Local CA Test <pid-timestamp>") so the test
  cert can never collide with production
- Mirrors the by-hash deletion loop from untrust_ca_macos
- Trap-cleanup on success or interrupt

Lives under tests/manual/ to signal "host-mutating, dev-only" — distinct
from tests/docker/install-trust.sh which is hermetic.

* test: relax bail-out in macOS trust test (safe alongside production)

The bail-out was overly defensive. The test cert uses a unique CN
("Numa Local CA Test <pid-ts>") that is strictly longer than the
production CN, so `security find-certificate -c $TEST_CN` cannot
substring-match the production cert. All deletes are by-hash, which
can only target the test cert's specific hash. Coexistence is
provably safe; document the reasoning in the header comment block
and replace the refusal with an informational notice.

98da440c84 feat: forward-by-default, auto recursive mode, Linux install fixes (#27)
* feat: auto recursive mode, fix Linux install

Auto mode (new default): probes a root server on startup; uses
recursive resolution if outbound DNS works, falls back to Quad9 DoH
if blocked. Dashboard shows mode indicator (green/yellow).

Linux install fixes:
- Add DNSStubListener=no to resolved drop-in (frees port 53)
- Configure DNS before starting service (correct ordering)
- Skip 127.0.0.53 in upstream detection
- `numa install` now does everything (service + DNS + CA)
- `numa uninstall` mirrors install (stop service + restore DNS)
- Extract is_loopback_or_stub() for consistent filtering

(169.254.169.253). Fixes internal hostname resolution on cloud VMs
where recursive mode can't resolve private DNS zones.

* refactor: single-pass resolv.conf parsing, eliminate redundancies

for mode in StatsResponse. Remove dead read_upstream_from_file.

* fix: macOS install health check, harden recursive probe

Verify numa is listening (API port) before redirecting system DNS on
macOS — if the service fails to start (e.g. port 53 in use), unload
the service and abort instead of breaking DNS. Probe up to 3 root
hints before declaring recursive mode unavailable. Validate IPs from
resolvectl to avoid IPv6 fragment extraction. Extract DEFAULT_API_PORT
constant.

- Move #[default] from Auto to Forward on UpstreamMode

06850de728 fix circular reference: detect DHCP DNS when scutil shows loopback
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.

c333705a0e fix needless return in trust_ca for Windows clippy
On Windows, the not(macos/linux) cfg block is the only path, so
clippy flags the return as needless. Use expression form instead.

5495107c9e add Windows support (Phase 1)
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.

cfd9a562af fix CA removal: delete by SHA-1 hash, update README with TLS
security delete-certificate -c fails when multiple certs match.
Now finds all certs by hash and deletes each individually.
Also updated README with HTTPS, service persistence, and TLS mentions.

3bfcd827ac add TLS, service persistence, blocking panel, query types
- Local TLS: auto-generated CA + per-service certs (explicit SANs, not
  wildcards — browsers reject *.numa under single-label TLDs). HTTPS
  proxy on :443 via rustls/tokio-rustls. `numa install` trusts CA in
  macOS Keychain / Linux ca-certificates.
- Service persistence: user-added services saved to
  ~/.config/numa/services.json, survive restarts.
- Blocking panel: renamed "Check Domain" to "Blocking" with sources
  display, allowlist management UI, unpause button.
- Query types: recognize SOA, PTR, TXT, SRV, HTTPS (type 65) instead
  of logging as UNKNOWN.
- Blocklist gzip: reqwest now decompresses gzip responses from CDNs.
- Unified config_dir() in lib.rs for consistent path resolution under
  sudo and launchd. TLS certs use /usr/local/var/numa/ (writable as
  root daemon).
- Dashboard UX: panel subtitles differentiating overrides vs services,
  better placeholders, proxy route display, 600px query log height.
- Deploy: make deploy handles build+copy+codesign+restart cycle.
- Demo: scripts/record-demo.sh for recording hero GIF with CDP.

10502f2db2 fix service restart: add codesign and make deploy target
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.

8f959ce0a5 add local service proxy with .numa domains
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.

ee776938c5 add auto-detect upstream, install script, release workflow
- 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

57c4742f09 harden Linux DNS config and fix review findings
- 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

4645df50e0 add Linux systemd service and DNS configuration
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.

2db44bd7d0 add system DNS auto-configuration (install/uninstall)
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.
