Health probes (probe_health/refresh_health) are type-aware: WireGuard
checks the last WG handshake timestamp, OpenVPN checks the tun/tap
interface, Tor checks the control-port GETINFO, and sshuttle/proxy
types do a TCP reachability probe to the remote endpoint. Results are
persisted via set_connection_status and wired into the health_monitor_loop
so the UI always has a current health snapshot without polling.
Per-peer fail-open semantics: VPN, SSH, and proxy connections default to
fail-closed (kill-switch stays active even when the tunnel is down).
Tor defaults to fail-open. The default can be overridden per-peer via
set_peer_failopen/effective_failopen. apply_routes skips the fwmark and
kill-switch rules for any fail-open peer whose connection health is not
"working", letting traffic fall back to direct routing transparently.
New generic admin-only connection CRUD endpoints (GET/POST/PUT/DELETE
/api/connectivity/connections, GET /<id>/health, PUT
/api/connectivity/peers/<peer>/failopen) are guarded by the existing
admin role check. connection.create, connection.update, connection.delete,
and peer.failopen are all registered in ROUTE_ACTION_MAP for the audit
hook so every change is recorded in the owner-visible change log.

Add AuditManager (api/audit_manager.py): JSONL append-only log at
data/api/audit/audit.log with SHA-256 hash chain for tamper detection,
verify endpoint, size-based rotation, and automatic redaction of secret
fields before any entry is written. Supports structured query (actor,
action, date range) and CSV export.
Wire an @app.after_request hook in app.py that fires on every mutating
/api/* request: captures actor, role, remote IP, and maps the route +
method to a human-readable action via ROUTE_ACTION_MAP. Explicit audit
entries for password_change and password_reset are added in
auth_routes.py so those events record the actor without logging secret
values.
Expose an admin-only blueprint (api/routes/audit.py):
GET /api/audit — paginated query
GET /api/audit/export — CSV download
GET /api/audit/verify — hash-chain integrity check
Register AuditManager in managers.py and add api/audit to
config_manager.py critical_data_paths so it is included in backups and
restored with other persistent state.
Add Activity page (webui/src/pages/Activity.jsx, admin-only) reachable
from the nav in App.jsx. New auditAPI helper in api.js covers all three
endpoints.
Tests: test_audit_manager.py (unit: hash chain, redaction, rotation,
query, csv, verify) and test_audit_hook_routes.py (integration: hook
fires on mutating routes, skips safe methods, records actor/ip/action,
backup-inclusion assertion).
