"""Encode and decode the native Shard protocol's named-tensor bundles.
The generated stubs give us message *structure*; they cannot enforce the
invariants that keep a distributed forward correct. A bundle whose declared
shape disagrees with its byte count, whose fragments leave a hole, or whose
checksum does not match is not a slightly-wrong activation — it is silently
wrong tokens for the rest of the generation. So decoding is validating: every
path into a tensor's bytes goes through :func:`decode_tensor`, which refuses a
payload it cannot fully account for.
Compression is a transport optimisation and is decided by the same policy layer
the existing HTTP seam already uses (``activation_compression``), so a node's
tuned thresholds apply to both transports.

"""Canonical conformance vectors for the native Shard protocol.
Two independently-written codecs that each round-trip their own output prove
nothing about each other. These vectors are the shared reference: Python builds
the canonical message, the bytes are committed under
`packages/node/native/testdata/`, and the C++ test parses those exact bytes and
asserts the same field values. A change that alters the wire meaning of a field
breaks the vector in both languages instead of drifting silently in one.
The vector deliberately exercises every field group the protocol promises to
carry — identity, epoch, fingerprint, range, phase, position, idempotency,
cache expectation, deadline, chunking, compression, checksum and a multi-
fragment named tensor — so it doubles as an executable inventory of the
contract.
