- aes67_web/cfg.c: cfg_register(group, defaults, validate, apply),
cfg_override_defaults() for project defaults, cfg_get(). Stored values
are loaded on register and merged over defaults (known keys, matching
types). NVS keeps only keys that differ from defaults, one JSON string
per group, so new firmware defaults still reach untouched settings.
- POST /api/config: type check against defaults, per-group validation,
nothing stored unless every group passes; 400 "group.key: reason".
Unknown keys/groups are ignored. Returns the new config.
- Core groups registered by their components with the UI's ranges:
ptp (aes67_ptp), aes67 (aes67_tx, incl. multicast range and mono_sum
=> 1 channel), net/inet (aes67_net), log (aes67_syslog).
- Project: PROJECT.def overrides (hostname p4-aes67, name P4 AES67) and
the "source" group in main/project_cfg.c.
- Config is stored only; nothing is applied live yet.
- Verified on board: defaults, valid save, 8 rejected values (nothing
stored), persistence across reboot, restore to defaults.
