Post-DHCP-incident hardening per HARDEN.md.
- apply guard: refuse (ConflictError, `force` overrides) when a
network-managed interface would end up in no zone; absent
`interfaces` key = hands-off, explicit `[]` = unassign-all
- surface `uncovered_interfaces` in firewall state (lo/wg* filtered)
+ advisory in /api/status/pending; zones.js banner + interfaces-picker
last-zone confirm
- target drift (Option A): absent or default-normalizing target is
unmanaged: not diffed, never re-set by apply; create_zone runs
--new-zone first and sets non-default targets only; importer omits
the target key for default zones
- FirewallToDhcpSync keeps stale DHCP ranges and flags them instead of
deleting; `dnsmasq` affected only on a real gateway mutation
- real pre-apply recovery snapshot in data/firewall/rules.json
({timestamp, default_zone, zones, config}); drop the empty post-apply
skeleton
- daemon shutdown: bounded grace for in-flight tasks + suppressed
teardown exception noise on SIGTERM
- also carries the firewall service-descriptions feature
(get_service_descriptions + service_descriptions state field + UI)
- tests + docs across firewall/status/state/sync/schema; ruff clean,
867 passing
- daemon: send full snapshot on connect; versions/tick now carry the
full state of one subsystem (subsystem + data); no legacy
updated/subsystems payloads; refresh_state and POST /status/refresh
broadcast per-subsystem versions with data
- client: modelSet() patches models in place; onMessage/topic refresh
retired; 3s initial-load fallback via new POST /api/status/refresh
- schema: lib/schema.py TypedDicts + hoover/schema.js defaults +
docs/state-model.md as single source of truth for state shapes
- system: poll at 1s, volatile metrics registered, dashboard uses a
dedicated system model (status model removed)
- firewall: refuse to strip both https and ssh from the default zone
(409, force override via UI confirm); set_zone_services persists
services to the declarative config; collector exposes default_zone
- UI: pages migrate to flat state shapes; post-mutation modelFetch
refreshes removed (WS delta covers it)
- tests: ws snapshot/delta/broadcast, refresh-state, schema types,
model-set/js ws handler and reconnect fallback
systemd: pre-create volatile /run paths so vacuum-walld's ProtectSystem=strict namespace setup cannot fail with 226/NAMESPACE — RuntimeDirectory=vacuum-wall nginx plus a tmpfiles.d spec (installed to /etc/tmpfiles.d/) covering /run/firewalld and /run/nginx.pid. Drop /run/sudo from ReadWritePaths: NOPASSWD children never need it, and its absence crash-looped restarts after sudo removed /run/sudo.
webui: run the auth session check before mounting the shell so logged-out visitors never flash the sidebar or a protected page; router guard and sidebar now react to auth state, and the login page renders full-bleed.
ws: cap refresh->reconnect episodes at 2 consecutive failures; if the WS path stays dead after a token refresh, abandon reconnection instead of looping refreshAuth forever (UI keeps working via REST until reload).
api: GET /api/network/interfaces now includes loopback and returns per-interface {config, runtime}; dashboard reads runtime.state (carrier counts as up) and the interfaces page filters lo client-side.
daemon: re-collect nginx state after lazy config migration (cached list went stale when the on-disk format changed under it), skip system_import.nginx when config.json already exists (re-parsing vacuum-wall's own generated sites is lossy), and poll nginx (60s) / acme (300s) state so file drift self-heals.
- update-vendor.sh now creates webui/vendor symlinks (htm.js)
- install.sh calls update-vendor.sh after package install
- Add vendor/.empty and webui/vendor/.empty as directory placeholders in git
- Register, view, and deactivate ACME accounts via API and UI
- 16-check validation framework for certificate issuance readiness
- DNS resolution, port, nginx, and firewall pre-flight checks
- External IP detection with NAT support and fallback providers
- Account card and settings modal in certificates page
- Guard certificate issuance behind account registration
- Update modal CSS to overlay-based approach
- 1000+ lines of tests for validation and account handlers
- Add quick modal, table, service status, and confirmation dialog components
- Refactor all pages (certs, dhcp, proxy, etc.) to use new component patterns
- Introduce refactor load utility and render guard for consistent UX
- Add hoover documentation and update AGENTS.md, architecture, overview
Phase 1-4: Networkd subsystem
- lib/network.py: systemd-networkd config renderer (.network INI files)
with full schema support: [Match], [Link], [Network], [Address], [Route],
[DHCPv4], [DHCPv6] sections. One Address/=DNS= line per value per spec.
Route sections use #N suffix per systemd.syntax(7).
- lib/network.py: generate_network_files() with 50-<name>.network prefix
and stale file cleanup
- lib/network.py: collect_upstream_dns() filters local/private DNS
- lib/network.py: infer_dhcp_ranges() and infer_zones() helpers
- daemon/handlers/network.py: routes for GET/POST /network/interfaces
and full apply with DNS upstream sync to dnsmasq
- webui/api/network.py: Flask blueprint for /api/network/* endpoints
- webui/api: interfaces page updated with IP config inline editing
- lib/state.py: networkd collector using parse_networkctl_status()
- system/sudoers.d/vacuum-walld: networkctl + systemd-network rules
- system/systemd/vacuum-walld.service: ReadWritePaths for /etc/systemd/network
- install.sh: ACME email now optional, configured from WebUI
- lib/acme.py: get_email() falls back to declarative config
Phase 5: Code review fixes
- daemon/server.py: path params now win over JSON body and query params
in request body merge (prevents config save name override)
- daemon/server.py: remove dead 'import re'
- daemon/handlers/network.py: replace Path.mkdir() with sudo mkdir
for /etc/systemd/network (ProtectSystem=strict compatibility)
- system/sudoers.d/vacuum-walld: pin systemctl to specific commands
(reload/is-active dnsmasq instead of wildcard)
- system/sudoers.d/vacuum-walld: restore !requiretty and section comment
- lib/network.py: remove unused _MANAGEMENT_PORTS constant
- webui/api/network.py: remove redundant body[\name\] = name in save_interface
Tests: 332 passing (110 new/updated), ruff clean
- Add daemon/ module with aiohttp server, sync client, and handler registry
- Add daemon/handlers/ for privileged operations (acme, dnsmasq, firewall, logs, nginx, wireguard)
- Add system/acme-deploy.py, vacuum-walld sudoers and systemd service
- Update API routes to use daemon client instead of lib/ directly
- Update lib/, tests/, and webui/ for new architecture
- Update docs and deployment scripts
- Fix WireGuard private key leak in API responses and config updates
- Update systemd service to serve from repo root with adjusted sandbox
- Add CLI flags, idempotency, and dev mode to install.sh
- Extract common utilities to lib/common.py and webui/api/common.py
- Migrate frontend to htmx for simpler, more maintainable UI
- Update docs to reflect current architecture and deployment model
- Vendor htmx dependencies per project requirements
Reflect config/ vs data/ split, install-time Jinja2 templating, auto-discovered
paths, ZeroSSL/ACME support, and the new firewall save-then-apply API in all
reference docs.
