RvfReader::from_bytes now sniffs the leading non-whitespace byte and
dispatches to a JSONL parser when it sees '{' or '['. The new
from_jsonl_bytes helper walks each line, validates that it is a JSON
object with a "type" field, and maps known types onto in-memory binary
segments so the rest of the pipeline keeps working unchanged:
type=metadata -> SEG_MANIFEST (name, version, architecture)
type=quantization -> SEG_QUANT (full JSON payload, default
quant_type filled in if absent)
type=* -> SEG_META (verbatim, bundled into one entry)
The binary-path "invalid magic" error now points operators at the JSONL
format so failures are explicit instead of degrading to null output, and
unrecognised content (non-UTF-8, no objects, missing type) returns a
detailed error rather than a silent partial parse.
The JSONL container intentionally does not carry the f32 weight matrix
- those ship as model.safetensors / model-qN.bin in the HuggingFace
bundle - so weights() returns None for JSONL inputs. Callers that need
the convolution weights must still load one of the sibling files.
Fixes the documented gap where pointing the sensing-server --model flag
at model.rvf.jsonl from the HuggingFace bundle errored with
"invalid magic at offset 0: expected 0x52564653, got 0x7974227B".
