feat: ADR-095/096 sparse attention — on-ESP32 temporal head + AETHER train wire (#513)#516
Conversation
…513) Two Proposed ADRs covering the integration of vendored ruvllm_sparse_attention v0.1.1 (released 2026-05-07, no_std + alloc validated on real ESP32-S3 per upstream ADR-192). * ADR-095 — adds a learned temporal head to the ESP32-S3 firmware via a Rust component compiled --no-default-features against the 376 KB rlib. Runs alongside the existing physics-only DSP, gated behind a Kconfig (8 MB only initially). Use cases: gesture recognition, fall classification with sequence context, breathing-quality scoring, on-device anomaly detection. Builds on ADR-018, ADR-039, ADR-081. * ADR-096 — adopts forward_gqa + KvCache for the AETHER (ADR-024) contrastive CSI embedding's temporal aggregation. Path-vendored workspace dep, A/B gate before flipping the inference default. ~30-100x speedup at long windows; streaming decode goes from O(N^2) recompute to O(log T) per new frame. Refs #513
… 1-3, #513) Implements Phases 1-3 of the ADR-096 roadmap: Phase 1: workspace integration - Add `ruvllm_sparse_attention` as a path-vendored workspace dep against `vendor/ruvector/crates/ruvllm_sparse_attention`, default-features=false, features=["fp16"]. Mirrors the no_std posture ADR-095 will need on the firmware side so both consumers share a single feature set. - Register `wifi-densepose-temporal` as workspace member. Phase 2: AETHER temporal head - `AetherTemporalHead` facade dispatches to a `SparseGqa` backend wrapping `SubquadraticSparseAttention`. Selection rule from ADR-096 §4.4 enforced at forward(): MHA branch when q_heads == kv_heads, GQA branch otherwise. - `Dense` backend reserved (returns typed `DenseBackendNotImplemented`) so config-time validation fails loudly instead of at forward(). - `TemporalHeadConfig::default_aether()` matches the AETHER training default per ADR-096 §3.1 (window=32, block=16, q=4, kv=1 → MQA). - Token 0 always wired as a global anchor — preserves AETHER's contrastive "session-start reference" role per ADR-024. Phase 3: smoke tests (5/5 passing) - forward at AETHER default config, both MHA and GQA dispatch paths, rejected dense backend, rejected non-divisible GQA ratio, and the long-window roadmap target (N=1000, the 10s @ 100Hz case from ADR-096 §3.1 — proves the kernel runs at lengths where dense MHA costs 10⁶ edge ops vs sparse 10⁴). Streaming `step()` deferred — KvCache lifecycle ties to PoseTrack per ADR-096 §8.5 and lands when the firmware-side ABI does (Phase 4+). Co-Authored-By: claude-flow <ruv@ruv.net>
… Phase 4, #513) Phase 4 of the #513 roadmap: ESP-IDF component skeleton at `firmware/esp32-csi-node/components/ruv_temporal/`. Source is complete and self-consistent; cross-compile to xtensa-esp32s3-none-elf is blocked by a known-broken esp-rs nightly snapshot (details in the component README). What's in the scaffold: - `Cargo.toml` — staticlib, no_std + alloc, deps on the path-vendored `ruvllm_sparse_attention` (matching ADR-096's host-side dep) and `esp-alloc`/`critical-section` for the no_std allocator and lock primitives. - `src/lib.rs` — public C ABI (init / push / classify / destroy / self_test) with `#[no_mangle]` exports, a `[#used]` keepalive table to defeat aggressive linker stripping, esp-alloc as the global allocator (heap region added at runtime by the firmware), and a loop-on-panic handler (Phase 5 will route through esp_system_abort). - `src/window.rs` — `FrameRing`, the rolling-window buffer that `ruv_temporal_push` writes to. Chronological iteration via `iter_chronological()` so the kernel sees oldest-first. - `include/ruv_temporal.h` — the public C header consumed by edge_processing.c. Threading contract documented inline (single dedicated FreeRTOS task, no internal locks). - `CMakeLists.txt` — runs `cargo +esp build` as an ESP-IDF pre-component-register step, then registers the static library through `idf_component_register` + `target_link_libraries(... INTERFACE ...)`. `shim.c` exists only because `idf_component_register` requires SRCS. - `.cargo/config.toml` + `rust-toolchain.toml` — pin the build to `xtensa-esp32s3-none-elf` and the `esp` toolchain channel so `cargo build` without flags Just Works once the toolchain is unblocked. - `README.md` — Phase status table, Phase 5 toolchain blocker explanation, and the espup install fix. ABI calls into edge_processing.c (Phase 6) and COM8 validation (Phase 7) follow once the cross-compile is unblocked. Closes nothing yet; advances #513. Co-Authored-By: claude-flow <ruv@ruv.net>
…nt (Phase 6, #513) Phase 6 of #513: C-side wiring for the on-device temporal head. Builds cleanly with feature OFF (default); 8MB binary delta is +96 bytes vs v0.6.4-esp32 — that's the no-op shim path. Feature ON depends on the Rust component (Phase 5, currently blocked by upstream esp-rs nightly). Files: - main/temporal_task.{c,h} — owns the FreeRTOS task lifecycle. Per ADR-095 §3.3 the task has its own 16 KB stack pinned to Core 1 and is fed via a 32-deep FreeRTOS queue. With feature OFF the .c file collapses to three ESP_ERR_NOT_SUPPORTED stubs so callers don't need #ifdefs at every call site. - main/temporal_task.h — defines rv_temporal_pkt_t (40 bytes, magic 0xC5110007 — next free in the existing 0xC5110001..0006 family) and the task lifecycle API. Build-time _Static_assert pins the wire format. - main/Kconfig.projbuild — new menu "On-device temporal head (ADR-095, #513)" with CONFIG_CSI_TEMPORAL_HEAD_ENABLED (default n) plus four runtime-tuneable knobs: TEMPORAL_INPUT_DIM (16), TEMPORAL_WINDOW_LEN (256), TEMPORAL_N_CLASSES (4), and TEMPORAL_CLASSIFY_PERIOD_MS (1000). - main/CMakeLists.txt — adds temporal_task.c to SRCS unconditionally (the .c file feature-gates internally), and adds ruv_temporal to REQUIRES only when the feature is enabled so default builds don't pull in the Rust component. - main/adaptive_controller.c — fast_loop_cb now extracts the 9 feature floats from the pkt it just built and pushes them into temporal_task_push_frame after the existing stream_sender_send. Non-blocking; queue-full drops are coalesced and logged 1/sec. - main/main.c — temporal_task_start() called right after adaptive_controller_init(). Wrapped in #ifdef so feature-off builds don't reference the (no-op-anyway) function. - components/ruv_temporal/CMakeLists.txt — restructured. Top-level Kconfig guard registers an empty component when the feature is off (avoids running cargo without a working toolchain). add_custom_command moved AFTER idf_component_register so it doesn't fire in script mode (required by ESP-IDF v5.4). Validation: - Firmware builds clean with default config (feature OFF) on ESP-IDF v5.4 / esp32s3 target. Binary 1062 KiB / 2 MiB partition, 48 % free. - Static assertion catches wire-format drift (rv_temporal_pkt_t size). - Host-side `cargo test -p wifi-densepose-temporal` still 5/5 from the earlier commit (no regression, this commit only touches firmware/). Phase 7 (flash to COM8 + soak) deferred this iteration — board is currently not enumerating on COM8; will pick up next iteration when the ESP32 is reattached.

The training/firmware boundary needs a stable serialization for the
temporal head's weights, distinct from the kernel scaffold and the
firmware ABI. This commit defines that format on the host side. The
firmware-side mirrored loader lands when the toolchain unblocks.
Format:
- Header (24 B): magic 'RVNE' / version 1 / dtype flag
(FP32 / FP16) / input_dim / n_q_heads / n_kv_heads / head_dim /
n_layers / n_classes / weights_len.
- Body: weights_len bytes of flat per-layer weights.
- Footer (4 B): CRC32 IEEE 802.3 over everything before, same
polynomial used by temporal_task.c so a blob produced here parses
on the firmware unchanged.
Layout decisions:
- Little-endian throughout (Xtensa native).
- Weights kept as Vec<u8> rather than Vec<f32>/Vec<f16> so the no_std
firmware loader (which may not have the `half` crate) can mmap and
read either dtype directly.
- Versioning is hard-break: bumping `version` means firmware refuses
to load. Optional fields go behind reserved flag bits, never by
field reorder. Documented inline.
Validation surface:
- `WeightBlobHeader::validate()` catches zero dims, invalid GQA
ratios (n_q_heads % n_kv_heads != 0), n_layers=0, n_classes<2.
Same checks fire from `WeightBlob::parse()` so the firmware can't
accidentally accept a blob the host should have rejected.
- `WeightBlob::parse()` enforces magic / version / size / CRC
before exposing weights to the caller.
Tests (8/8 passing, alongside 5/5 sparse smoke = 13/13 total):
- roundtrip_fp32, roundtrip_fp16
- parse_rejects_bad_magic, _wrong_version, _size_mismatch,
_crc_corruption, _invalid_gqa_ratio_in_header
- header_constants_match_wire_layout (anchor)
What's deliberately NOT in this commit:
- The firmware-side mirrored loader (deferred to the iteration that
unblocks the esp Rust toolchain — no point shipping a parser that
can't be compiled).
- Per-layer weight ordering. The blob is a flat byte-buffer; the
interpretation of per-layer offsets is the kernel's contract,
documented in the eventual model module (ADR-095 §3.2 follow-up).
Co-Authored-By: claude-flow <ruv@ruv.net>
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.
Co-Authored-By: claude-flow <ruv@ruv.net>
Closes the format contract on the firmware side. Source-only — Phase 5
toolchain blocker still prevents actually compiling, but when it
unblocks this is one less thing to write under time pressure.
- src/weights.rs — no_std mirror of v2/.../weights.rs. Same magic
('RVNE'), same version 1, same CRC32-IEEE polynomial (matches the C
side in temporal_task.c). Bit-for-bit lockstep with the host: a
blob produced by host WeightBlob::serialize() parses here as a
WeightBlobView byte-for-byte.
Borrowed-slice parse design: the firmware loader receives weights
via mmap'd EMBED_FILES or NVS read into a heap buffer. The parser
takes &[u8] with no copy — view fields point into the caller's
buffer. Caller is responsible for keeping the buffer alive for the
view's lifetime.
Loader errors map to esp_err_t-style codes via
weight_load_err_to_esp() so the C ABI can surface specific failure
modes (ESP_ERR_INVALID_ARG for magic/version/size, ESP_ERR_INVALID_CRC
for corruption, ESP_ERR_INVALID_SIZE for shape validation failures).
- src/lib.rs — ruv_temporal_init now optionally validates a non-NULL
weights blob. NULL pointer is still allowed during the Phase 4/5
bring-up window (kernel forward isn't actually consuming weights
yet), but when caller passes a real blob we parse + sanity-check
declared dims against runtime arguments. Catches deploy bugs at
init() rather than at first classify() — the firmware Tmr Svc work
in v0.6.4 taught us that classify-time crashes are the worst kind.
- README.md — Phase 6 marked done (verified by 8MB firmware build with
feature off in commit 7994af8). Added module map table covering
lib.rs / window.rs / weights.rs / ruv_temporal.h / shim.c.
What's deliberately NOT in this commit:
- Cross-compile validation. Same toolchain blocker as before.
- Kernel-side wiring of weights into the forward pass. That's
Phase 6+ of the firmware roadmap — once the kernel is wired,
weights become a required arg, not an optional one.
- Tests on the firmware side. They'd need build-std working to run;
16/16 host tests cover the format end-to-end via the lockstep
polynomial.

The structural advantage that's the entire point of ADR-096: O(log T) per new token via decode_step against an accumulated KvCache, vs O(N²) recompute for dense MHA. This commit lands the API and proves the numerical equivalence at the last position. API: - AetherTemporalHead::step(q_new, k_new, v_new, &mut cache) Single-token decode. Appends (k_new, v_new) to cache, runs decode_step(q_new) against the now-updated cache, returns the new position's output. - AetherTemporalHead::make_cache(capacity) Convenience constructor — caller doesn't need to import ruvllm_sparse_attention to size a cache. Per ADR-096 §8.5 the natural lifetime is per-PoseTrack (re-ID) or per-session (online classification); when the track drops, drop the cache. - KvCache re-exported at the crate root. Contract: - q_new/k_new/v_new must each have seq == 1. Multi-token q is the prefill path (forward), not decode_step. - Cache lifetime is the caller's. The crate enforces shape via make_cache so callers can't mismatch kv_heads / head_dim / block_size. - KvCache fill is the caller's problem. Upstream H2O heavy-hitter eviction is opt-in; this crate's wrapper doesn't pre-pick a policy. Tests (18/18 total now passing): - streaming_step_matches_forward_at_last_position — central claim: 16-token sequence, append k/v one at a time via step(), compare the streamed last-token output to forward(full Q,K,V)[N-1]. max_abs_err < 1e-3 (currently passes well under that bound for the 0.1-magnitude activations the test uses). - step_rejects_multi_token_q — contract enforcement. - make_cache_returns_kvcache_with_correct_shape — wiring smoke, confirms (capacity, kv_heads, dim, block_size) ordering is correct through the make_cache wrapper. Test config uses MHA shape (q_heads == kv_heads) because the upstream decode_step is wired to the MHA branch; the GQA decode path is on upstream's roadmap and lands in a separate ADR-096 follow-up when it does.

#513) Validates the central performance claim of ADR-096 with a runnable benchmark. Single-run wall-clock, pure-Rust vs pure-Rust on x86_64 host. Real numbers, not just analytic argument. Results (N=64..1024): | N | Dense (ms) | Sparse (ms) | Speedup | |--------|-----------:|------------:|--------:| | 64 | 0.262 | 0.141 | 1.86× | | 128 | 1.120 | 0.335 | 3.34× | | 256 | 4.129 | 0.711 | 5.81× | | 512 | 19.230 | 2.356 | 8.16× | | 1024 | 71.904 | 3.389 | 21.21× | Asymptotic check: 64→1024 is 16× more tokens. Dense's 274× cost growth matches N² (256× = 16²). Sparse's 24× growth matches N log N (16 · log(1024)/log(64) ≈ 27). The complexity claim is empirically supported. ADR-096 §3.1 honest-framing paragraph predicted N=64 would be overhead-bound; we measured 1.86× there, consistent with the ADR's warning that AETHER's current `window_frames=100` default is below the inflection point where sparse pays. What this commit adds: - examples/bench_speedup.rs — measures dense_attention (upstream reference), AetherTemporalHead.forward (this crate's wrapper), and SubquadraticSparseAttention.forward (raw, to confirm the wrapper isn't introducing overhead — it isn't, the two are within noise). - benches_results.md — captured table + asymptotic check + caveats (config used, what the benchmark doesn't measure, how to run). Run it: cargo run -p wifi-densepose-temporal --example bench_speedup --release What's NOT measured here: - Decode-step latency (already proved correct at last-token, not yet timed against a hypothetical O(N²) dense decode — they're structurally not comparable anyway). - Memory footprint of KvCache + FP16 (matters on firmware, not host). - GQA dispatch — this bench uses MHA shape so dense and sparse operate on identical tensors. Real AETHER will want MQA per TemporalHeadConfig::default_aether(), which halves KV memory. Co-Authored-By: claude-flow <ruv@ruv.net>
Closes the documentation gap on the host-side ADR-096 surface. The crate has 7 commits, 5 source modules, 4 test suites, 2 examples, and a captured benchmark; reviewers and downstream consumers needed a landing page. Sections: - Quick start (5-line forward + 7-line streaming) - Backends + selection rule (SparseGqa MHA-vs-GQA dispatch) - Streaming semantics (cache lifetime, eviction policy, the headline correctness test) - Weight blob format with the host/firmware lockstep note - Examples (init_random_blob, bench_speedup) with run lines - Tests (18/18 passing as of 247794a, broken down by suite) - Status of ADR-096 claims with concrete evidence for each - Status of ADR-095 surface (firmware) + the toolchain blocker - Carry-forward of the open questions still applicable from §8 The README intentionally cross-links to: - docs/adr/ADR-096 for design rationale - components/ruv_temporal/ README for the firmware mirror - benches_results.md for the captured speedup curve Doesn't claim more than is proven. Each ADR-096 claim either has a test or a benchmark cited as evidence; the partial claim (30-100× at long windows) explicitly says 21× was the measured number, not 30×. Co-Authored-By: claude-flow <ruv@ruv.net>
Closes the Dense placeholder from earlier commits. Now both backends implement forward(); only SparseGqa supports streaming step()/KvCache, which is the structural gap dense MHA can't bridge by design. Dense path: - src/dense.rs new — DenseHead wraps upstream dense_attention. Stores causal flag and (cloned) config. forward() is a one-line delegation; no GQA dispatch (dense_attention upstream requires q_heads == kv_heads). - AetherTemporalHead::Dense changed from a unit variant to Dense(DenseHead). Construction succeeds for any valid TemporalHeadConfig where backend is Dense. - AetherTemporalHead.step() returns BackendDoesNotSupportStreaming for Dense — there is no dense-MHA-with-KV-cache equivalent and offering one would silently swallow the ADR-096 §3.2 structural argument. - AetherTemporalHead.make_cache() likewise — there's no cache to size for a dense kernel. Errors: - New TemporalError::BackendDoesNotSupportStreaming variant covers the Dense-step / Dense-make_cache cases. Specific so callers can fall back to forward() instead of giving up entirely. - TemporalError::DenseBackendNotImplemented retained for v0.1 back-compat (no consumers depend on it post-this-commit, but removing a public variant is a hard break). Future work can deprecate it once downstream callers move off. Tests (19/19 passing): - dense_backend_returns_typed_error → renamed and rewritten as dense_backend_forward_runs_with_matching_shape: constructs a Dense head, runs forward over (32, 4, 4, 16) Q/K/V, asserts output shape. - New dense_backend_step_returns_streaming_error: constructs Dense, attempts make_cache, expects BackendDoesNotSupportStreaming. - All 8 weight blob, 2 blob e2e, 3 streaming, 5 other smoke tests unchanged and still passing. This commit completes the ADR-096 §5 A/B gate: callers can now run the same Q/K/V through both backends and compare outputs / latency. The §5 four-gate validation (contrastive loss within 1%, rank-1 within 1pp, Spearman ≥0.95, latency ≥5×) becomes a runnable proposition, not a future task — though the actual gate run requires trained AETHER weights, which is its own track. Co-Authored-By: claude-flow <ruv@ruv.net>
) Establishes the kernel-level output-divergence envelope between the two backends — what §5's downstream-metric gate (contrastive loss, rank-1, Spearman) would calibrate against. Two regimes: 1. Saturated pattern (window ≥ N, block ≥ N): sparse and dense visit the same edge set, so divergence reflects only float accumulation order. **Asserted < 1e-4** at N=32, heads=4, dim=16. Tight bound. 2. Realistic sparse (window=16, block=32, N=256): real approximation, real divergence. **Measured max_abs_err = 5.22e-3, mean = 1.79e-3** on the deterministic test inputs. Sanity-checked finite + < 1.0 so structural breakage (NaN, softmax overflow) trips a panic, but the specific numbers are *baseline data* not a hard contract — the §5 gate cares about downstream task metrics, not bit-equality. Why this is in the test suite rather than a benchmark: - It runs in <0.2s, no need to gate behind --release. - The saturated-pattern bound IS a hard contract — if that breaks the kernel changed semantics in a way the API hides, and we want CI to catch it. - Printing the realistic-pattern numbers (eprintln, visible with --nocapture) gives a known-good reference point to compare future builds against. Test count is now 21/21 across the crate (6 smoke + 8 weight blob + 2 blob e2e + 3 streaming + 2 dense-vs-sparse). Co-Authored-By: claude-flow <ruv@ruv.net>
…into the tch graph (#513) ADR-096 train integration. Additive — does NOT modify model.rs. The existing WiFiDensePoseModel forward stays bit-equivalent for back-compat. New code lives in temporal_aether.rs behind the `aether-sparse-temporal` feature flag (which itself requires `tch-backend`). Architecture: tch::Tensor [T, in_dim] ──── tch nn::Linear (q/k/v projections) ↓ [T, q_heads*head_dim] etc ↓ tch_to_tensor3 (CPU, f32, 1× copy) ↓ ruvllm_sparse_attention::Tensor3 ↓ AetherTemporalHead::forward() ↓ Tensor3 [T, q_heads, head_dim] ↓ tensor3_to_tch (1× copy) ↓ tch::Tensor [T, q_heads*head_dim] ↓ tch nn::Linear (output projection) ↓ tch::Tensor [T, in_dim] Why additive rather than swapping `apply_antenna_attention` / `apply_spatial_attention` in model.rs: those are over antenna and spatial axes, not temporal — ADR-096 §8.1 was right that AETHER doesn't currently HAVE a temporal-axis attention. This commit adds that path without disturbing the others, so the §5 validation gate can A/B the two options before flipping the production default. Scope notes: - B=1 prefill only this version. Multi-batch lands when §5 turns green and we need to take perf seriously. The forward expects `[T, in_dim]` not `[B, T, in_dim]`; documented in the file. - Streaming step() bridge deferred — KvCache lifecycle ties to PoseTrack per ADR-096 §8.5, which is signal-side not train-side. - Two CPU memory copies per call (in + out). For training-rate forwards (~100/sec at batch 16) this is negligible vs the actual attention work; for inference-rate streaming it'd be the bottleneck and a zero-copy path is the natural follow-up. Build verification: - Source compiles cleanly with cargo check on the host crate (`-p wifi-densepose-temporal`, 21/21 tests still passing). - The train crate's tch-backend build is environmentally blocked on this Windows machine — torch-sys fails to link against the system PyTorch 2.11 + MSVC 14.50 toolchain. This predates this commit and affects all tch-bound code paths in the workspace. CI runners with working libtorch will verify the new module builds; the source follows the same nn::Linear / Module patterns the existing model.rs uses. Feature gating ensures default builds are byte-equivalent. Off by default; enable with `--features aether-sparse-temporal`. Co-Authored-By: claude-flow <ruv@ruv.net>

Asymptotic check (16× tokens): dense growth 274× ≈ 16² (theory: O(N²)), sparse growth 24× ≈ 16·log(1024)/log(64) (theory: O(N log N)). The complexity claim from ADR-096 §3.1 is empirically supported on this hardware.
Firmware build (run today):
Default config (feature OFF) builds clean: 1062 KiB / 2 MiB partition, 48 % free, +96 bytes vs v0.6.4-esp32 — exactly the no-op shim path.
What's blocked / out of scope for this PR
torch-syswon't link against system PyTorch 2.11 + MSVC 14.50. Predates this PR; affects all tch-bound paths.Honest characterization
This PR delivers infrastructure, not a trained model. Specifically:
step()is numerically equivalent toforward()at the last position; wire format is consistent across host + firmware Rust + firmware C; saturated-pattern divergence is FP-noise-bound.What this does NOT do: it doesn't ship a trained classifier, doesn't actually run on COM8, doesn't run the §5 gate. Those are gated on real weights, board reattach, and the toolchain unblocking — all noted in the relevant docs.
Reviewer questions to watch for
0xC5110007is the next free magic in the0xC5110001..0006family. Sanity-check that allocation before the on-device path emits packets.aether-sparse-temporalfeature flag default is OFF, gated behindtch-backend. Is that the right gate, or should it default ON whentch-backendis enabled?🤖 Generated with claude-flow
