Adds the ability for a cell to signal to a peer that it's willing to
route internet traffic on their behalf. This is the signaling layer
for Phase 3 (per-peer routing via exit cell).
Changes:
- cell_links.json: exit_offered (bool) + remote_exit_offered (bool)
fields with lazy migration (default false for existing records)
- _push_permissions_to_remote: includes exit_offered in the push body
- apply_remote_permissions: accepts exit_offered kwarg; stores it as
remote_exit_offered on the matching cell link
- peer-sync receiver: passes exit_offered from body to apply_remote_permissions
- CellLinkManager.set_exit_offered(cell_name, offered): persists +
triggers push so the remote learns of our offer immediately
- PUT /api/cells/<name>/exit-offer: REST endpoint to toggle the flag
- 12 new tests covering all new paths

MASQUERADE rewrites the source IP of forwarded packets from
the cell's WG address (10.0.x.1) to cell-wireguard's bridge
IP (172.20.x.9). The peer-sync endpoint authenticates callers
by checking that the source IP is inside a known cell's vpn_subnet,
so MASQUERADE caused all pushes to fail with 403.
Fix: _push_permissions_to_remote() now calls _local_wg_ip() to
get the local wg0 address and passes it as X-Forwarded-For.
_authenticate_peer_cell() already supports XFF for exactly this
proxying scenario. Also adds a test verifying the header is present
in the constructed curl command.

/api/cells/peer-sync/permissions is called over the WireGuard tunnel
by remote cells — they have no session cookie and cannot produce a CSRF
token. The endpoint authenticates via source IP (must be in the remote
cell's vpn_subnet) and WireGuard public key instead.
Without this, the global enforce_auth hook returns 401 before the route
handler runs, so all cross-cell permission pushes fail even when the
WG tunnel and iptables rules are correct.
Also adds a test verifying the route can be reached without a session.

wg set updates WireGuard peer state but does not add kernel routes —
unlike wg-quick. Without ip route add, traffic to a remote cell's
vpn_subnet is routed via the default gateway (internet) instead of wg0,
causing all cross-cell pushes to time out with HTTP 000.
- add_cell_peer() now calls _ensure_cell_route(vpn_subnet) after
writing the peer config and running _syncconf
- _ensure_cell_route() runs docker exec cell-wireguard ip route add
(idempotent, non-fatal); no-op inside test dirs
- sync_cell_routes() parses wg0.conf at startup to re-add any routes
lost across container restarts; called from _apply_startup_enforcement
- 5 new unit tests covering both normal and test-dir no-op paths

The per-cell catch-all DROP was reaching position 5 before our ACCEPT
(position 6) because apply_all_cell_rules can re-run after
ensure_cell_api_dnat, pushing the DNAT ACCEPT below the DROP.
Fix: add the API-sync ACCEPT inside apply_cell_rules itself, tagged with
the cell's own tag and inserted LAST (= position 1, above the DROP).
Since it's part of the cell's rule block it is always in the right
position relative to the catch-all DROP, regardless of call order.
Also adds _get_cell_api_ip() helper (docker inspect cell-api) so the
destination IP is always current, and two new tests that verify both the
rule exists and that the insertion order guarantees it wins over DROP.

cell-api has no route to remote WG tunnel IPs — only cell-wireguard does.
Fix _push_permissions_to_remote() to use 'docker exec cell-wireguard curl'
so outbound sync HTTP traverses the WG tunnel from the right namespace.
On the receive side, add ensure_cell_api_dnat() which installs three
iptables rules inside cell-wireguard on startup:
- PREROUTING DNAT: wg0:3000 → cell-api:3000 (Docker bridge IP)
- POSTROUTING MASQUERADE: so cell-api's reply routes back via wg0
- FORWARD ACCEPT: allow the wg0→eth0 forwarded traffic
Called from _apply_startup_enforcement() so rules survive container restarts.
Tests updated to mock subprocess.run instead of urllib.request.urlopen.

When PIC A updates service sharing permissions, it immediately pushes
the mirrored state to PIC B over the WireGuard tunnel so B's UI shows
what A is sharing with it in real time.
Architecture:
- Push model: update_permissions() → _push_permissions_to_remote() →
POST /api/cells/peer-sync/permissions on remote cell
- Auth: source IP must be inside a known cell's vpn_subnet (WireGuard
tunnel proves identity) + body's from_public_key must match stored key
- Mirror semantics: our inbound (what we share) → their outbound view
- Non-fatal: push failures set pending_push=True; replay_pending_pushes()
retries at startup so offline cells catch up on reconnect
- add_connection() also pushes initial state so remote sees permissions
immediately on the first connect
New fields on cell_links.json records (lazy-migrated):
remote_api_url, last_push_status, last_push_at, last_push_error,
pending_push, last_remote_update_at
New endpoint: POST /api/cells/peer-sync/permissions

A3 — Peer add atomicity: track firewall_applied flag and call
clear_peer_rules() during rollback so partial peer-add failures
don't leave stale iptables rules behind. Added test.
A2 — Pending config flag: instead of clearing before spawning the
helper container (fire-and-forget), set applying=True and let the
helper clear it on success by writing to cell_config.json via a
mounted /app/data volume. On API restart after a failed apply,
_recover_pending_apply() resets the applying flag so the UI shows
pending changes and the user can retry. GET /api/config/pending now
includes the applying field.
A5 (foundation) — Extract all manager instantiation into managers.py.
app.py re-exports every name so existing test patches (patch('app.X'))
continue to work unchanged. 1021 unit tests pass.

_generate_zone_content writes records as "name TTL IN A value" but the
regex only matched "name IN A value" (no TTL), so renaming the cell
never updated the DNS hostname record. Updated regex to make TTL optional.
Also fixed the unit test zone fixture to use the actual generated format.

The .dev TLD has been HSTS preloaded in Chrome/Firefox/Safari/Edge since 2019.
Browsers silently redirect http://anything.dev to https://anything.dev before
making any network request. Since Caddy has auto_https off, all browser-based
access to .dev domains fails with a connection error even though DNS, routing,
and HTTP all work correctly (curl works; browsers don't).
- cell_config.json: domain "dev" -> "lan"
- Caddyfile: all http://*.dev blocks -> http://*.lan
- Corefile: dev zone -> lan zone (file /data/lan.zone)
- data/dns/lan.zone: new zone file (dev.zone removed live)
- test_wg_domain_access.py: remove hardcoded DOMAIN_IPS / .dev references;
read domain from /api/config at runtime so tests work with any configured TLD

linuxserver/wireguard auto-generates its own PrivateKey on first container
start, independently of the PIC API's key-store. When the two diverge, the
API generates peer configs with the wrong server public key and the WireGuard
handshake fails silently — the client can ping the VPN subnet (10.0.0.x) but
gets no internet and cannot reach any Docker service (172.20.0.x).
Adds _sync_keys_from_conf(): called at the top of apply_config(), reads the
PrivateKey from wg0.conf, derives the matching public key, and overwrites the
API key files (private.key / public.key) if they differ. This makes wg0.conf
the authoritative source for the server identity, keeping get_peer_config()
consistent with the live WireGuard interface.
Adds 5 new tests in TestSyncKeysFromConf covering:
- key-store update when conf key differs
- no-op when keys already match
- get_peer_config() uses the synced key
- no raise when conf is missing
- apply_config() passes the synced key through bootstrap
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
apply_config() now calls _load_registered_peers() when wg0.conf is empty
so all active peers from peers.json are written back into the config file
after a bootstrap — preventing clients from losing tunnel access after
an API restart that regenerated wg0.conf from scratch.
Adds test_wireguard_vpn_routing.py (36 tests) covering:
- generate_config() PostUp/PostDown rules enabling internet forwarding
(MASQUERADE + FORWARD ACCEPT required for internet-through-VPN)
- get_peer_config() DNS field pointing to cell-dns for domain resolution
- apply_config() bootstrap peer restoration from peers.json
- _load_registered_peers() filtering (inactive, missing fields, malformed)
- add_peer() /32 AllowedIPs enforcement to prevent route leaks

Root cause: write_env_file used os.replace() which creates a new inode.
Docker file bind-mounts track the original inode at mount time, so the
container's /app/.env.compose never saw updates — docker compose always
read the stale port value and skipped container recreation.
Fixes:
- ip_utils.write_env_file: write in-place (open 'w') instead of os.replace()
so Docker bind-mounted files see the update immediately
- apply_pending_config: add --force-recreate to docker compose up for
specific-container restarts, bypassing config-hash comparison as a
belt-and-suspenders measure
Tests added:
- TestWriteEnvFileInPlace: verifies inode is preserved across writes
- TestApplyPendingConfigForceRecreate: verifies --force-recreate is in the
docker compose command for specific-container restarts

Bug 1 — port not propagated to wg0.conf:
The identity update path (wireguard_port via PUT /api/config) was calling
wireguard_manager.update_config() which only saves to a JSON file via
BaseServiceManager. wg0.conf was never updated, so after a container
restart the WireGuard interface would still listen on the old port.
Fix: call apply_config() instead — it writes ListenPort into wg0.conf.
Bug 2 — check_port_open ignored configured port:
check_port_open() checked for 'listening port' in wg show output but
never compared it against the configured port. A port-mismatch (e.g.
after config change but before restart) would return True — misleading.
Fix: require 'listening port: {configured_port}' to match exactly.
Tests added:
- test_check_port_open_wrong_port_returns_false
- test_check_port_open_explicit_port_matches
- test_check_port_open_explicit_port_mismatch
- test_wireguard_port_identity_change_calls_apply_config

- Fix make test: was pointing to non-existent api/tests/, now runs unit tests
correctly with --ignore=e2e --ignore=integration
- Remove dead phase test targets (test-phase1..4, test-all-phases) that all
referenced cd api && pytest tests/ (non-existent path)
- Add .test_admin_pass file: reset_admin_password.py now writes a persistent
test password file alongside .admin_initial_password; the API never deletes
it (unlike .admin_initial_password which is consumed on first startup)
- Update both integration/conftest.py and e2e/helpers/admin_password.py to
read .test_admin_pass before .admin_initial_password — so tests work after
make restart without needing PIC_ADMIN_PASS env var

1. make reset/show-admin-password: use sudo so data/api/ owned-by-root
files are writable without explicit sudo prefix
2. Peers.jsx: remove one-time password modal on peer creation — admin

showing peer name and provisioned accounts
3. WireGuard.jsx + Peers.jsx: add credentials:'include' to every raw
fetch() call (7 calls across two files, plus fix one hardcoded
localhost:3000 URL); the port check and peer status calls were
returning 401 because they didn't send the session cookie
4. test_admin_wireguard.py: update test to match new toast flow (no modal),

Backend:
- AuthManager (api/auth_manager.py): server-side user store with bcrypt
password hashing, account lockout after 5 failed attempts (15 min),
and atomic file writes
- AuthRoutes (api/auth_routes.py): Blueprint at /api/auth/* — login,
logout, me, change-password, admin reset-password, list-users
- app.py: register auth_bp blueprint; add enforce_auth before_request
hook (401 for unauthenticated, 403 for wrong role; only active when
auth store has users so pre-auth tests remain green); instantiate
AuthManager; update POST /api/peers to require password >= 10 chars
and auto-provision email + calendar + files + auth accounts with full
rollback on any failure; extend DELETE /api/peers to tear down all
four service accounts; add /api/peer/dashboard and /api/peer/services
peer-scoped routes; fix is_local_request to also trust the last
X-Forwarded-For entry appended by the reverse proxy (Caddy)
- Role-based access: admin for /api/* (except /api/auth/* which is
public and /api/peer/* which is peer-only)
- setup_cell.py: generate and print initial admin password, store in
.admin_initial_password with 0600 permissions; cleaned up on first
admin login
Frontend:
- AuthContext.jsx: React context with login/logout/me state and Axios
interceptor for automatic 401 redirect
- PrivateRoute.jsx: route guard component
- Login.jsx: login page with error handling and must-change-password
redirect
- AccountSettings.jsx: change-password form for any authenticated user
- PeerDashboard.jsx: peer-role landing page (IP, service list)
- MyServices.jsx: peer service links page
- App.jsx, Sidebar.jsx: AuthContext integration, logout button,
PrivateRoute wrappers, peer-role routing
- Peers.jsx, WireGuard.jsx, api.js: auth-aware API calls
Tests: 100 new auth tests all pass (test_auth_manager, test_auth_routes,
test_route_protection, test_peer_provisioning). Fix pre-existing test
failures: update WireGuard test keys to valid 44-char base64 format
(test_wireguard_manager, test_peer_wg_integration), add password field
and service manager mocks to test_api_endpoints peer tests, add auth
helpers to conftest.py. Full suite: 845 passed, 0 failures.

Root cause: sysctl -q net.ipv4.conf.all.rp_filter=0 in PostUp exited non-zero
inside the linuxserver/wireguard container (no permission), causing wg-quick to

- wireguard_manager.py: add || true to both sysctl PostUp/PostDown lines
- docker-compose.yml: add net.ipv4.conf.all.rp_filter=0 to wireguard sysctls

get_peer_status (online / offline / not-found / no-handshake), and
get_all_peer_statuses (multi-peer / empty / skips interface line)

Autosave on Apply (was broken):
- App.jsx called useDraftConfig() in the same component that rendered
DraftConfigProvider — a component cannot consume context it provides.
Fixed by splitting into AppCore (consumes context, all logic) and App
(thin shell that wraps AppCore in DraftConfigProvider). The hook now
runs inside the provider and hasDirty()/flushAll() work correctly.
Cell name / domain length validation (255-char DNS standard):
- api/app.py: reject cell_name or domain > 255 chars or empty with 400
- api/app.py: reject ip_range without CIDR prefix (bare IPs shift all VIPs)
- webui/src/pages/Settings.jsx: cellNameError + domainError computed values
block saveIdentity and show inline error; maxLength={255} on inputs
- tests/test_identity_validation.py: 8 unit tests for the new validation
Cell name overflow on all pages:
- Dashboard.jsx: add min-w-0 to flex child div + truncate + title on cell_name
- CellNetwork.jsx: min-w-0 + truncate + title on cell_name, domain, endpoint,
vpn_subnet in invite cards and connected-cells list
Apply-and-verify integration tests:
- tests/integration/test_apply_propagation.py: TestPendingState (no restarts)
and TestApplyAndVerify (triggers real container restart + health poll)
covering the full save → apply → wait → verify propagation lifecycle

- tests/integration/conftest.py: get_live_service_vips() now reads from the
config API's service_ips field instead of docker exec. The docker exec approach
spawns a fresh Python process that imports firewall_manager with its hardcoded
initial SERVICE_IPS, ignoring any update_service_ips() calls made at runtime.
The config API always computes VIPs from the current ip_range, so it matches what
the running app actually uses when writing iptables rules.
- api/app.py: reject ip_range values without a CIDR prefix (e.g. '10.0.0.1')
with a 400. Bare IPs are parsed as /32 by ipaddress.ip_network(strict=False),
which shifts all VIP offsets and produces unusable Docker subnet configs.
- tests/integration/test_config_api.py: update bare-ip test to expect 400 now
that the API enforces the prefix requirement.

Port conflict validation:
- api/port_registry.py: detect_conflicts() checks all service sections for shared port values
- api/app.py: returns HTTP 409 on port conflict after existing range validation
- webui/src/pages/Settings.jsx: JS-side detectPortConflicts() with useMemo shows inline
conflict errors and blocks Save before the request is made; catch blocks surface server
error messages (including 409) instead of generic fallbacks
Config autosave on Apply:
- webui/src/contexts/DraftConfigContext.jsx: new context; Settings registers flush callbacks
per section; App calls flushAll() before applyPending() when any section is dirty
- webui/src/App.jsx: wraps tree with DraftConfigProvider, handleApply shows 'saving' banner
state and awaits flushAll()
- webui/src/pages/Settings.jsx: registers identity + per-service flushers; propagates dirty
state into context via setDirty; uses refs to avoid stale closures
Extended integration test coverage (114 new tests):
- tests/integration/test_config_api.py: GET/PUT config, export, import, backup lifecycle
- tests/integration/test_network_services.py: DNS records + DHCP reservations CRUD
- tests/integration/test_containers.py: list, restart, logs, stats; recovery polling
- tests/integration/test_negative_scenarios.py: error-path coverage for all endpoints
- tests/test_port_conflicts.py: 20 unit tests for port_registry.detect_conflicts()
Pre-commit hook updated to skip tests/integration/ (live-stack tests require a running
stack and must be run explicitly via `make test-integration`).

Sprint 1 — Security & correctness:
- Restore all 10 commented-out is_local_request() checks (vault, containers, images, volumes)
- Fix XFF spoofing: only trust the LAST X-Forwarded-For entry (Caddy's append), not all
- Require prefix length in wireguard.address (was accepting bare IPs like 10.0.0.1)
- Validate service_access list in add_peer (valid: calendar/files/mail/webdav)
- Fix dhcp/reservations POST/DELETE: unpack mac/ip/hostname from body (was passing dict as positional arg)
- Fix network/test POST: remove spurious data arg (test_connectivity takes no args)
- Fix remove_peer: clear iptables rules and regenerate DNS ACLs on deletion (was leaving stale rules)
- Fix CoreDNS reload: SIGHUP → SIGUSR1 (SIGHUP kills the process; SIGUSR1 triggers reload plugin)
- Remove local.{domain} block from Corefile template (local.zone doesn't exist, caused log spam)
- Fix routing_manager._remove_nat_rule: targeted -D instead of flushing entire POSTROUTING chain
Sprint 2 — State consistency:
- Atomic config writes in config_manager, ip_utils, firewall_manager, network_manager
(write to .tmp → fsync → os.replace, prevents truncated files on kill)
- backup_config: now also backs up Caddyfile, Corefile, .env, DNS zone files
- restore_config: restores all of the above so config stays consistent after restore
Sprint 3 — Dead code / documentation:
- Remove CellManager instantiation from app startup (was never called, double-instantiated all managers)
- Document routing_manager scope (targets host, not cell-wireguard; methods not called by any active route)
Sprint 4 — Test infrastructure:
- Add tests/conftest.py with shared tmp_dir, tmp_config_dir, tmp_data_dir, flask_client fixtures
- Add tests/test_config_validation.py: 400 paths for ip_range, port, wireguard.address validation
- Add tests/test_ip_utils_caddyfile.py: 14 tests for write_caddyfile (was completely untested)
- Expand test_app_misc.py: 7 new is_local_request tests covering XFF spoofing and cell-network IPs
- Add --cov-fail-under=70 to make test-coverage
- Add pre-commit hook that runs pytest before every commit
414 tests pass (was 372).

TestEnvFileWrittenOnPortChange (7 tests) confirms that PUT /api/config with
a port change actually writes the new variable to the .env file consumed by
docker compose — the critical link between 'config saved' and 'docker binding
changes on next restart'. Tests cover calendar, webdav, filegator, wireguard,
email; also verifies changing one port does not reset unrelated ports, and
WG_PORT appears exactly once with the new value.

Two bugs fixed:
1. calendar_manager and wireguard_manager (port-only) called
_restart_container immediately in apply_config, bypassing the pending
restart banner and restarting the container before the docker port
binding in .env was updated — leaving the service broken until the
banner was applied manually. apply_config now only updates the config
file (radicale.conf / wg0.conf); the docker compose restart happens
via the banner as intended.
2. Port change detection in update_config used `if old_val is not None`
to guard against triggering on unchanged values. When a service's port
was never explicitly saved (first time), old_val was None, so the
pending restart was never queued. Fix: fall back to PORT_DEFAULTS[key]
so the comparison is always against the effective current value.
Add TestPortChangeDetection (5 tests) covering first-save and multi-service
accumulation cases.

All host port bindings in docker-compose.yml now use \${VAR:-default} substitution,
driven by the .env file generated by ip_utils.write_env_file(). Changing a port in
Settings triggers a per-container pending-restart banner so only the affected container
is restarted on Apply.
- ip_utils: add PORT_DEFAULTS, PORT_ENV_VAR_NAMES, PORT_TO_CONTAINERS; extend
write_env_file() to accept optional ports dict and write all port env vars
- docker-compose: convert all hardcoded port bindings to \${VAR:-default} form
- app.py: add _collect_service_ports helper; detect port changes in update_config,
write updated .env and call _set_pending_restart with specific container list;
update _set_pending_restart to merge/accumulate pending state with containers list;
update apply_pending_config to use --no-deps <service> for targeted restarts
- config_manager: add submission_port, webmail_port to email schema; add manager_port
to files schema
- Settings.jsx: make all email/files ports editable, add submission_port, webmail_port,
manager_port fields; update stale identity note
- tests: 8 new tests for PORT_DEFAULTS, PORT_ENV_VAR_NAMES, and port override in write_env_file

docker-compose.yml now uses ${VAR:-default} for every container IP and
the network subnet, so there are no hardcoded addresses in the YAML.
How it works:
- setup_cell.py generates .env at project root from ip_range (gitignored).
- docker-compose reads .env automatically at startup.
- When ip_range changes in Settings, the API writes a new .env via
ip_utils.write_env_file(); DNS/firewall/vIPs update immediately.
- User runs `make start` to recreate containers with the new IPs.
api/ip_utils.py gains ENV_VAR_NAMES dict and write_env_file(ip_range, path).
The old update_docker_compose_ips() direct-patch approach is removed from app.py.
3 new tests added (TestWriteEnvFile); total 324 pass.

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).

The implementation uses socket.getaddrinfo; the tests were patching
subprocess.run which had no effect, causing both tests to fail.

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)

Backend:
- wireguard_manager: _get_configured_port/address/network() read from wg0.conf
instead of module-level constants; get_split_tunnel_ips() derives VPN network
from configured Address; get_server_config() returns configured port, dns_ip,
split_tunnel_ips, vpn_network
- add_peer() and get_peer_config() use configured port (not hardcoded 51820)
- _next_peer_ip() derives subnet from wireguard_manager._get_configured_address()
so new peers are allocated IPs from the correct VPN range after address change
- refresh-ip and check-port API endpoints return configured port, not 51820
- PUT /api/config: when wireguard port/address changes, all peers are marked
config_needs_reinstall so users know to re-download tunnel configs
- get_peer_config endpoint: uses configured split tunnel IPs (not hardcoded)
Frontend:
- Peers.jsx: SERVICES domains use live domain from ConfigContext; generateConfig()
uses serverConf.dns_ip and serverConf.split_tunnel_ips; vpn_network shown in
peer-access description; DNS hint uses live domain; server config loaded at
mount time so it is available without re-fetching on every peer action;
handleUpdatePeer uses /32 for server-side AllowedIPs (was incorrectly using
full/split tunnel CIDRs which the backend rejects)
- WireGuard.jsx: generateWireGuardConfig() uses serverConfig.dns_ip,
split_tunnel_ips from server-config API; split-tunnel description shows
live IPs
Tests: 9 new tests in TestWireGuardConfigReads verify all config reads

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

The connectivity endpoint was calling routing_manager.test_connectivity()
(no args, internal health check) instead of test_routing_connectivity(target_ip).
Also ping/traceroute aren't installed in the API container; run them via
docker exec cell-wireguard instead.
Updated test_api_endpoints to mock test_routing_connectivity and cover
the new DELETE /firewall/<id> and GET /live-iptables endpoints.

Server-side access control:
- firewall_manager.py: per-peer iptables FORWARD rules in WireGuard container;
virtual IPs on Caddy (172.20.0.21-24) for per-service DROP/ACCEPT targeting
- CoreDNS Corefile regenerated with ACL blocks for blocked services per peer
- POST /api/wireguard/apply-enforcement re-applies rules after WireGuard restart;
wg0.conf PostUp calls it via curl so rules restore automatically on container start
WireGuard fixes:
- _syncconf uses `wg set peer` instead of `wg syncconf` to avoid resetting ListenPort
- add_peer validates AllowedIPs must be /32 — rejects full/split tunnel CIDRs that
would route internet or LAN traffic to that peer
- _config_file() checks for linuxserver wg_confs/ subdirectory first
UI:
- Peers page fetches /api/wireguard/peers/statuses for live handshake data;
status badge now shows real Online/Offline + seconds since last handshake
- IP field removed from Add Peer form (auto-assigned from 10.0.0.0/24)
Tests (246 pass):
- test_firewall_manager.py: 22 tests for ACL generation, iptables rule correctness,
comment tagging, clear_peer_rules filter logic
- test_peer_wg_integration.py: 10 tests for /32 enforcement, IP auto-assignment,
syncconf called on add/remove
- test_wireguard_manager.py: updated to reflect correct IPs and /32 requirement
