Closes the host→file→firmware loop on the Phase 1 weight format. Real
.rvne artifact emitted from the example, parsed back through filesystem
in the e2e test, byte-identical across two seeded runs.
- examples/init_random_blob.rs — produces a 41,244-byte deployable blob
matching the AETHER default head shape (input_dim=16, q_heads=4,
kv_heads=1 [MQA], head_dim=32, layers=2, classes=4 — staying coherent
with TemporalHeadConfig::default_aether so a real trainer can drop
in this shape with one search-and-replace). Uses xorshift64* with a
fixed seed (0xC511_0007_DEAD_BEEF) for reproducibility.
Per-layer weight count derivation lives in the example (Wq + Wk +
Wv + Wo, plus a final classifier head) so the kernel's expectation
is anchored in code rather than a comment that drifts.
- tests/blob_e2e.rs — two new tests, 15/15 total now passing:
* realistic_blob_roundtrips_through_filesystem — writes a 25+ KB
blob to std::env::temp_dir(), reads it back, parses, validates.
Mirrors what the firmware loader will do once the toolchain
unblocks (mmap NVS or EMBED_FILES → parse).
* deterministic_seed_produces_byte_identical_blobs — same seed
produces byte-identical output, twice. This is what makes a
witness-bundle (ADR-028) over trained weights meaningful.
Verified by running the example with an explicit out path:
cargo run -p wifi-densepose-temporal --example init_random_blob -- \
v2/target/example-output/model_init.rvne
→ 41244 bytes, parses clean, dtype/shape/CRC all good.
What this isn't yet:
- Not a trained model. Random init only.
- Not a kernel forward over the blob. That requires the firmware
Rust component to compile (Phase 5 — toolchain blocker).
- Not wired into wifi-densepose-train. ADR-096 §8.1 flagged that
the AETHER train crate doesn't currently have a temporal-axis
attention; that integration is a separate piece of work.
