alias. It can auto-detect `.gns` file layout information, unpack 2-, 4-, 8-,
and 16-bit samples, and expose multi-channel recordings as independent RF
output streams.
- Reworked
[`ION_GSMS_Signal_Source`](https://gnss-sdr.org/docs/sp-blocks/signal-source/#implementation-ion_gsms_signal_source)
support for ION GNSS SDR metadata files. The source now validates and
deduplicates requested streams, honors file offsets, block headers/footers,
and omitted cycle counts, and stops finite captures cleanly with a guarded
valve tail. Chunk unpacking now handles word endianness, padding, shifts,
repeated lump patterns, repeated stream IDs, standard integer encodings, and
FP32 streams as `float` or `gr_complex` outputs.
- Improved Galileo HAS robustness and ICD compliance, including stricter MT1
validation, correct cache/Do-Not-Use handling, TOW fallback for E6 HAS pages,
preserved mask/IOD correction context, and corrected HAS application in
