Two bugs caused DNS to fail when the domain name changes:
1. generate_corefile() hardcoded 'cell' as the zone name instead of
using the configured domain — on startup it would silently reset any
domain change back to 'cell'
2. apply_domain() regex replaced ALL non-dot zones (including local.cell)
with the new domain → duplicate zone blocks → CoreDNS crash
Fix: add a domain parameter to generate_corefile/apply_all_dns_rules,
add _configured_domain() helper in app.py, and delegate Corefile updates
in apply_domain() to generate_corefile() so the logic is in one place.
Also parameterise SERVICE_HOSTS ACL entries via the domain argument.

When ip_range changes in Settings, the new subnet is now applied to:
- DNS zone records (network_manager.apply_ip_range)
- Caddy virtual IPs (firewall_manager.ensure_caddy_virtual_ips)
- iptables per-service rules (firewall_manager.update_service_ips)
- docker-compose.yml static IPs if writable (ip_utils.update_docker_compose_ips)
New module ip_utils.py derives all container IPs from the subnet using
fixed offsets so the entire stack stays consistent from one setting.
321 tests pass (72 new tests added for ip_utils, apply_ip_range, update_service_ips).

- NetworkManager.bootstrap_dns_records(): creates A records for all
cell services (api, webui, calendar, files, mail, webmail, webdav,
<cell_name>) using their static container IPs — only runs when the
zone file doesn't exist yet (idempotent)
- API startup: _bootstrap_dns() thread reads cell_name/domain from
config_manager and calls bootstrap — runs alongside enforcement thread
- Fix: add_dns_record(data) and remove_dns_record(data) now correctly
unpack dict kwargs instead of passing dict as positional arg
- Fix: remove duplicate cell{} block in config/dns/Corefile

Site-to-site WireGuard tunnels between PIC cells with automatic DNS forwarding.
Each cell generates an invite JSON (public key, endpoint, VPN subnet, DNS IP,
domain); the remote cell imports it to establish a bidirectional tunnel and
CoreDNS forwarding block so each cell's domain resolves across the mesh.
Backend:
- CellLinkManager: invite generation, add/remove connections, live WireGuard
handshake status; stores links in data/cell_links.json
- WireGuardManager: add_cell_peer() accepts subnet CIDRs (not /32) and an
optional endpoint for site-to-site peers; _read_iface_field() reads port,
address, and network directly from wg0.conf at runtime instead of constants
- NetworkManager: add/remove CoreDNS forwarding blocks per remote cell domain
- app.py: /api/cells/* routes; _next_peer_ip() derives VPN range from
configured address so peer allocation follows any address change
Frontend:
- CellNetwork page: invite panel (JSON + QR), connect form (paste JSON),
connected cells list (green/red status, disconnect button)
- App.jsx: Cell Network nav entry and route
Tests: 25 new tests across test_wireguard_manager, test_network_manager,
test_cell_link_manager (263 total)

Changes:
- ConfigContext.jsx: React context that loads /api/config once; exposes domain,
cell_name, refresh() — wraps entire app in App.jsx
- Email/Calendar/Files pages: replace hardcoded 'mail.cell', 'calendar.cell',
'files.cell', 'webdav.cell' with domain from ConfigContext; hostname updates
immediately after Settings save (refreshConfig() called on save)
- /api/status: cell_name and domain now read from stored _identity in config_manager,
not hardcoded 'personal-internet-cell' / 'cell.local'
- network_manager.apply_cell_name(old, new): updates hostname A-record in primary
zone file and reloads CoreDNS; called from PUT /api/config when cell_name changes
- Old identity captured before save so apply_cell_name gets the correct old value
- Settings EmailForm: smtp/imap ports are read-only with note (docker-compose.yml level)
- Settings FilesForm: port is read-only with note (Caddy proxies on 80 externally)
- Settings CalendarForm: port labeled "Internal port; clients use 80 via Caddy"
Tests added:
- test_apply_cell_name_renames_host_record
- test_apply_cell_name_noop_when_same

config_manager restore_config and import_config previously injected zero-filled
entries (port=0, domain='') for every service schema regardless of whether that
service was in the backup/import data. Removed this logic — only restore what's
actually in the backup.
network_manager.apply_domain now:
- updates dnsmasq.conf domain= line (reload cell-dhcp)
- rewrites Corefile zone blocks to the new domain name
- renames and rewrites the primary zone file $ORIGIN + SOA records
- reloads CoreDNS
Tests added first (TDD):
- test_restore_does_not_zero_unconfigured_services
- test_restore_does_not_zero_import
- test_apply_domain_updates_corefile (zone file + Corefile)
- test_apply_domain_updates_dnsmasq
- test_apply_config_writes_dhcp_range / ntp_servers
- test_apply_config_updates_mailserver_env / no_domain_no_restart

Each service manager now has apply_config() that writes to the actual config:
- network: dhcp_range → dnsmasq.conf (reload cell-dhcp), ntp_servers → chrony.conf
(restart cell-ntp), domain → dnsmasq.conf domain= line
- email: domain → mailserver.env OVERRIDE_HOSTNAME + POSTMASTER_ADDRESS,
restart cell-mail
- wireguard: port/address/private_key → wg0.conf ListenPort/Address/PrivateKey,
restart cell-wireguard
- calendar: port → radicale config hosts=, restart cell-radicale
PUT /api/config now calls apply_config() after persisting JSON, and returns
{restarted: [...], warnings: [...]} so Settings UI can show which containers
were restarted. _restart_container() helper added to BaseServiceManager.

Service manager fixes (connectivity tests):
- email_manager: replace telnet with socket.create_connection for SMTP/IMAP;
replace nslookup with socket.getaddrinfo for DNS; exclude unconfigured domain
from success (email healthy=False now correctly means ports refused, not missing domain)
- calendar_manager: replace localhost:5232 with cell-radicale:5232;
fix database check to test dir writability instead of file existence (files created on demand)
- file_manager: replace localhost:8080 with cell-webdav:80; add top-level success key
- network_manager: replace nslookup with socket.getaddrinfo;
add success key to dhcp_test and ntp_test return values
- routing_manager: exclude iptables_access from success
(iptables runs in cell-wireguard, not API container)
- wireguard_manager: add success key to no-arg test_connectivity result
Health history UI:
- SvcCol reads data?.status?.running || data?.status?.status — handles nested health check shape
Result: network/wireguard/calendar/files/routing/vault all healthy=True.
Email healthy=False is correct — mail server needs ≥1 account before Dovecot starts.
