- Extract all decode/decrypt into a dependency-free C99 core
(include/victronble.h, src/victronble_core.c): victronble_decode(),
is_product_adv/key_matches pre-filters, NAN sentinels, LE accessors.
- AES-128-CTR behind a hook: weak-symbol bundled tiny-AES default,
runtime override (victronble_set_aes_ctr) for PSA/mbedTLS/hardware.
- Arduino VictronBLE class becomes a thin wrapper over the core
(registry + nonce dedup + rate limit); public C++ API unchanged,
NAN converted back to the legacy 0 convention.
- Host test vectors (tests/vectors): openssl-generated ciphertext,
independent of the bundled AES; all five payload shapes + negatives.
- Zephyr module: zephyr/module.yml + Kconfig (CONFIG_VICTRONBLE) +
observer backend (victronble_zephyr.{h,c}) — scan cb pre-filters and
queues, dedicated decode thread, listener callbacks, slow passive
scan defaults, stats counters. docs/ZEPHYR_PORT.md records the plan.
- library.properties: fix URL (gitea, not the nonexistent GitHub).
