- Both olimex_esp32_c6_evb and olimex_esp32_c6_evb_pn532 drivers now sign every API request with X-Request-Time / X-Request-Sig headers using HMAC-SHA256(api_secret, METHOD:path:unix_timestamp) - Board model gains api_secret column (nullable, default None) - boards.py edit route saves api_secret from form - edit.html adds API Secret input with cryptographic Generate button - If api_secret is empty/None, headers are omitted (backward compat)
