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

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).

`make reinstall` wipes config/ then `make setup` creates an empty
Caddyfile (ensure_file just touches it). Add write_caddyfile() to
ip_utils.py that generates the full reverse-proxy config from ip_range,
cell_name, and domain. Call it from setup_cell.py so fresh installs
always get a valid Caddyfile. Also regenerate it in app.py whenever
ip_range, domain, or cell_name changes so Caddy stays in sync.

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).
