The mgmt API already always serves HTTPS (the host identity cert), but on a
loopback bind with no token it ran unauthenticated — any local process could
drive it. Make auth required ALWAYS:
- new mgmt_token::load_or_generate(): token precedence is --mgmt-token > env
PUNKTFUNK_MGMT_TOKEN > persisted ~/.config/punktfunk/mgmt-token > freshly
generated 32-byte hex, persisted 0600 in KEY=VALUE form (so the bundled web
console can source it directly as a systemd EnvironmentFile — one source of
truth). config_dir() made pub(crate).
- parse_serve() resolves the token via load_or_generate() when unset, so a bare
`serve` Just Works with auth on and no operator step.
- mgmt::run() drops the loopback no-token exemption and requires a token;
require_auth()'s unauthenticated fallback now returns 401. The paired-cert
(mTLS) branch is unchanged — Apple client + library auth unaffected.
- web /api proxy: 503 (legible) instead of forwarding an empty bearer.
- tests: test_app/test_app_native default a token, send() auto-attaches the
bearer; blank-token test asserts the new "no token" refusal. 80 pass.
- docs: mgmt module doc + host.env.example reflect always-on auth + auto-gen.
Compiles, clippy/fmt clean, openapi no drift. Part B (bundle the web console into
apt, auto-wired to this token) follows.
