Automated release from CI pipeline

Changes:
feat(adr-260): RuField MFS spec + vendor/rufield submodule (ruvnet#1061)

ADR-260 (Accepted — v0.1 reference stack): RuField, the open specification
for camera-free multimodal field sensing — one FieldEvent/FieldTensor/
FusionGraph/PrivacyClass/ProvenanceReceipt model above WiFi CSI/CIR/BFLD,
UWB, BLE Channel Sounding, mmWave radar, ultrasound, subsonic, infrared,
and quantum sensors.

Published standalone as github.com/ruvnet/rufield and vendored here as the
vendor/rufield submodule (the vendor/rvcsi pattern — not a v2/ workspace
member). v0.1 reference stack: 6 crates, 60 tests/0 failed, clippy-clean.
All benchmark metrics SYNTHETIC (simulator ground truth, no hardware).

Automated release from CI pipeline

Changes:
refactor(beyond-sota): ADR-154 M3 — clear §7.4 P3 backlog (22 de-magic + 6 boundary tests, backlog 36→0) (ruvnet#1057)

• refactor(signal): de-magic motion.rs tuning constants (ADR-154 §7.4 #18)

Lift the bare fusion weights, normalization scales, confidence-indicator
weights, and adaptive-threshold clamp bounds in motion.rs out of the
scoring functions into named, documented EMPIRICAL-DEFAULT consts. Values
are bit-identical to the prior literals — this is cleanup, no behaviour
change.

Adds boundary/characterization tests pinning current behaviour:

• motion_tuning_consts_unchanged_from_literals (consts == old literals)
• doppler_component_saturates_at_full_scale (/100 then clamp(0,1))
• correlation_score_zero_below_n2_boundary (n<2 guard)
• temporal_variance_zero_below_two_history (len<2 guard)
• adaptive_threshold_engages_at_history_boundary (history 9 vs 10)

• refactor(signal): gesture.rs euclidean length guard + de-magic (ADR-154 §7.4 #12)

• Add a debug_assert! to euclidean_distance documenting the same-dimension
  caller contract: zip() silently truncates on a length mismatch, so a
  mismatch is now loud in debug builds while the release operating path and
  output are unchanged.
• De-magic the bare 1e-10 confidence epsilon into a documented const
  CONFIDENCE_SECOND_BEST_EPSILON (value unchanged).

Tests pinning current behaviour:

• confidence_epsilon_unchanged_from_literal
• dtw_empty_sequence_is_infinite (n=0/m=0 boundary)
• euclidean_distance_equal_length_is_l2 (same-dim contract)

Co-Authored-By: claude-flow ruv@ruv.net

• refactor(signal): de-magic longitudinal.rs drift thresholds (ADR-154 §7.4)

Lift the bare drift-detection literals (7-day baseline, 2-sigma z-score,
3-day sustained, 7-day escalation, EMA alpha, cosine epsilon) into named,
documented EMPIRICAL-DEFAULT consts encoding the module's Key Invariants.
The duplicated >= 7 in is_ready/is_ready_at now share one const. EMA alpha
kept as the exact 0.05 literal (1.0 - 0.95_f32 is not bit-identical in f32).
Values unchanged.

Tests:

• drift_consts_unchanged_from_literals
• is_ready_at_day_boundary (day 6 vs 7)
• cosine_similarity_zero_vector_is_zero (zero-norm guard)

Co-Authored-By: claude-flow ruv@ruv.net

• refactor(signal): de-magic division/zero-norm epsilons + boundary tests (ADR-154 §7.4)

De-magic the bare division-guard epsilons in four modules into named,
documented consts (values unchanged) and pin the previously-untested
zero-norm / zero-variance / degenerate boundaries:

• cross_room.rs: COSINE_SIMILARITY_EPSILON (1e-9) + test_cosine_similarity_zero_vector
• multiband.rs: PEARSON_DENOMINATOR_EPSILON (1e-12) + pearson_correlation_zero_variance
• intention.rs: LEAD_TIME_MIN_ACCEL (1e-10) + lead_time_zero_for_static_stream
• hampel.rs: ZERO_MAD_EPSILON (1e-15) + test_zero_half_window_error
  • test_zero_mad_constant_window; documented hampel_filter # Errors

Each module also gets a *_unchanged_from_literal const-pin test.

Co-Authored-By: claude-flow ruv@ruv.net

• refactor(signal): de-magic rf_slam + attractor_drift constants (ADR-154 §7.4)

rf_slam.rs:

• NS_PER_DAY (86_400_000_000_000.0), MIGRATION_MIN_SPAN_DAYS (1e-9), and the
  fixed-map defaults (FIXED_MAP_ASSOC_RADIUS_M/MIN_SIGHTINGS/MIN_COHERENCE)
  lifted out of inline literals (values unchanged).
• migration_zero_span_is_zero_rate pins the single-sighting zero-span guard.

attractor_drift.rs:

• METRIC_BUFFER_CAPACITY (365), STABLE_CENTER_WINDOW (10) de-magicked.
• Documented the implicit recent.len()>=1 divide-safety in the PointAttractor
  branch (guaranteed by the count < min_observations guard).
• analyze_min_observations_boundary pins the off-by-one boundary.

Each module gets a *_consts_unchanged_from_literals pin test.

• refactor(signal): de-magic coherence.rs variance floor + default decay (ADR-154 §7.4)

Completes the M1 #9 de-magic for coherence.rs: the four bare 1e-6 variance-floor
literals (update_reference floor + coherence_score/per_subcarrier_zscores epsilon)
collapse to one VARIANCE_FLOOR const, and the inline 0.95 default decay becomes
DEFAULT_EMA_DECAY. Values unchanged.

Tests:

• drift_consts_unchanged_from_literals extended (VARIANCE_FLOOR, DEFAULT_EMA_DECAY)
• coherence_score_finite_with_zero_variance pins the floor's effect

Co-Authored-By: claude-flow ruv@ruv.net

• refactor(signal): de-magic calibration.rs thresholds + min-frames default (ADR-154 §7.4 #2)

Lift the bare calibration literals into named EMPIRICAL-DEFAULT consts (values
unchanged, bit-identical; calibration is off the Python proof path):

• DEFAULT_MIN_FRAMES (600) — was repeated across all four tier constructors
• AMP_STD_FLOOR (1e-12) z-score divisor floor
• MOTION_AMP_Z_THRESHOLD (2.0) / MOTION_PHASE_DRIFT_THRESHOLD (π/6) — the two
  motion_flagged sites now share one definition
• SUBTRACT_MIN_NORM (1e-30) baseline-subtraction guard

Test calibration_consts_unchanged_from_literals pins all five and asserts every
tier constructor shares DEFAULT_MIN_FRAMES.

Co-Authored-By: claude-flow ruv@ruv.net

• refactor(signal): de-magic fusion_quality + temporal_gesture constants (ADR-154 §7.4)

fusion_quality.rs:

• CONTRADICTION_PENALTY (0.8) and CONTRADICTION_BOUND_HALFWIDTH (0.1) named.
• no_contradiction_is_identity pins the n=0 boundary (penalty 0.8^0 = 1.0,
  zero-width bounds).

temporal_gesture.rs:

• CONFIDENCE_SECOND_BEST_EPSILON (1e-10, mirrors gesture.rs) and
  NORM_QUANTIZATION_SCALE (1000.0) named.

Each module gets a *_consts_unchanged_from_literals pin test. Values unchanged.

Co-Authored-By: claude-flow ruv@ruv.net

• docs(adr-154): record Milestone-3 — §7.4 row #21-45 P3 backlog cleared

Replace the lumped #21-45 backlog row with the enumerated M3 resolution: 22
magic constants de-magicked into named EMPIRICAL-DEFAULT consts (each pinned ==
prior literal), 6 boundary/characterization tests, ~4 doc-only, across 11
modules; not-real findings reported + skipped (unreachable attractor_drift
div0, non-existent gesture thresholds, proof-path features.rs). Update residual
P3 rows #2/#12/#17/#18 to RESOLVED, the deferred count (36 -> 0), the scope
field, and the Horizon-ledger one-liner. §7.4 backlog fully cleared across
M0-M3. CHANGELOG [Unreleased] entry added.

Validation: signal lib --no-default-features 476/0/1; --features cir 476/0;
workspace 3,275/0; Python proof PASS, hash f8e76f21...46f7a UNCHANGED.

Changes:
feat(beyond-sota): ADR-156 M2 — RaBitQ unbiased distance estimator (rigorous published negative on strict-K) (ruvnet#1056)

• feat(ruvector): RaBitQ unbiased distance estimator (ADR-156 M2)

Implement the real Gao & Long (SIGMOD 2024) RaBitQ contribution on top of
the existing Pass-2 rotation: an unbiased estimator of the inner product /
squared distance recovered from the 1-bit code plus 8 B/vec per-vector side
info (residual_norm + x_dot_o), used to rerank the candidate set instead of
raw Hamming.

• src/estimator.rs (new): EstimatorSketch, SideInfo, EstimatorQuery,
  DistanceEstimator (estimate_inner_product / estimate_sq_distance /
  ranking_key / cosine_ranking_key), EstimatorBank (topk_estimated[_cosine],
  with_centroid). Zero-centroid simplification documented; paper-faithful
  centroid path also built.
• src/rotation.rs: extract apply_padded() (full padded FHT frame the code
  lives in); apply() now truncates apply_padded(). No behaviour change.
• lib.rs: export estimator types.

Additive + backward-compatible: Pass-1 Sketch / Pass-2 SketchBank / WireSketch
wire format unchanged; all external callers use Pass-1 and are unaffected.

Co-Authored-By: claude-flow ruv@ruv.net

• test(ruvector): estimator strict-K coverage harness (ADR-156 M2)

Add measure_estimator (cosine rerank) + measure_estimator_euclidean to the
coverage harness, on the BIT-IDENTICAL fixture / cluster centres / query
stream / cosine ground truth as measure_pass1/measure_pass2 — apples-to-apples
sign-Hamming vs unbiased-estimator-rerank.

Regression tests:

• estimator_rerank_not_worse_than_sign (>= sign-only Pass-2 on a fixed fixture)
• estimator_coverage_is_deterministic
• estimator_coverage_report (--nocapture prints the strict-K table)

MEASURED strict-K (candidate_k=K=8): Pass-1 36.13% -> Pass-2-sign 46.39% ->
estimator-cosine 49.71%. Still short of the ADR-084 90% strict bar; estimator
reaches 95.12% at candidate_k=24 (vs sign 91.60%). Published negative.

Co-Authored-By: claude-flow ruv@ruv.net

• docs(ruvector): record RaBitQ estimator measured negative (ADR-156 §11, ADR-084)

• sketch_bench: estimator cosine/euclid columns in the coverage table.
• ADR-156 §11 (new): estimator formula + zero-centroid simplification stated
  honestly; strict-K coverage table; RESOLVED-NEGATIVE verdict (49.71% strict,
  short of 90%); pinning test names. §5 #2 + §10.5 updated.
• ADR-084 'Pass 2b' (new): estimator landed + measured strict-K vs the bar.
• CHANGELOG [Unreleased]: ADR-156 §11 Milestone-2 entry.

Changes:
perf(beyond-sota): ADR-154 M2 — FFT planner hoist (1.84x, bit-identical) + 3 honest perf nulls + boundary tests (ruvnet#1055)

• perf(signal): hoist FFT planner across subcarriers (ADR-154 §7.4 #20)

compute_multi_subcarrier_spectrogram called compute_spectrogram once per
subcarrier, and each call built a fresh FftPlanner + re-planned the same
length-window_size FFT. Hoist the plan + window out of the per-subcarrier
loop via a new compute_spectrogram_with_plan core that takes a pre-planned
Arc and pre-built window. compute_spectrogram delegates to it
(unchanged behaviour); the multi-subcarrier path plans once and reuses.

MEASURED-HOT (dsp_perf_bench, this box): at 56 subcarriers, window 128,
fresh-planner-per-subcarrier 467.88 μs -> hoisted-plan 254.75 μs = 1.84x;
window 256: 627.27 μs -> 448.39 μs = 1.40x. Plan-forward cost alone is
~1.86 μs (w128), x56 subcarriers ~= the removed delta.

Output is bit-identical: multi_subcarrier_hoisted_plan_bit_identical
compares f64::to_bits of every spectrogram value + freq/time resolution
against the per-call fresh-planner path across all 4 window functions x
{power,magnitude} on a 56-subcarrier matrix. The numeric STFT body is the
old loop verbatim; only plan/window construction is lifted.

• test(signal): boundary/tolerance tests for ADR-154 §7.4 #14 #16 #19

Three "+ test" backlog gaps closed — pure additions, no behaviour change
(phase_align refactor is internal: estimate_phase_offsets still returns the
identical offset vector; a counted core is split out only to observe the
iteration count).

#14 cir.rs fft_operator — fft_operator_within_tolerance_of_dense_canonical56:
the opt-in FFT Φ/ΦH path changes the witness hash, so pin it numerically
CLOSE to the dense path (not silently divergent). Asserts the full Cir
output (every tap within 1e-2·dominant, dominant idx/ratio, active_tap_count,
ranging_valid, rms_delay_spread) on the production canonical-56 config
across τ ∈ {20,50,90} ns. Extends the existing HT20/single-τ test.

#16 phase_align.rs — refinement_terminates_at_iteration_cap_when_not_converging:
forces non-convergence (tolerance=0.0, unreachable) and asserts the loop
runs exactly max_iterations then returns — proving the cap, not convergence,
bounds the loop (no infinite spin). Companion
refinement_converges_before_cap_on_easy_input proves the cap is an upper
bound, not the only exit.

#19 csi_ratio.rs — ratio_finite_at_and_below_1e_12_epsilon: the module
implements the CSI ratio as the conjugate product H_i·conj(H_j) (no
division), so it is finite even at/below the 1e-12 magnitude boundary a
naive H_i/H_j division would need an epsilon to guard. Pins finiteness +
bit-exact conjugate product at the boundary (zero target → zero, never
inf/NaN), through the amplitude/phase extraction.

§7.4: #20 MEASURED-HOT (×ばつ spectrogram FFT-plan hoist, bit-identical);
#5/#6/#7 MEASURED-NULL (benched, not hot, left as-is — sub-μs / stack-only /
alloc-once); #8 MEASUREMENT-ONLY (per-call ×ばつ56 eigh cost; eigenvalue/BLAS
backend un-buildable on this Windows host, number deferred to a BLAS box, NOT
fabricated; also corrects the finding — extract_perturbation reuses cached
modes, the recompute is in estimate_occupancy). #14/#16/#19 RESOLVED (tolerance

• bench(signal): committed P2 bench-first benches (ADR-154 §7.4 #5/#6/#7/#8/#20)

New dsp_perf_bench.rs backs every Milestone-2 perf verdict with a committed
criterion bench — no speedup claimed without a before/after number here, and
a benched NULL is the proof a micro-opt was unnecessary (the §5.x "already
amortized" pattern). Registered in Cargo.toml [[bench]].

MEASURED (this box, criterion medians):
#20 spectrogram_multi_subcarrier (fresh vs hoisted plan):
MEASURED-HOT — 467.88→254.75 μs (1.84x) @ sc56/w128; 627.27→448.39 μs
(1.40x) @ sc56/w256. Optimized in the prior commit.
#5 multistatic_attention/weights: MEASURED-NULL — 181 ns (2 nodes) ..
848 ns (8 nodes); sub-μs, no hot-path alloc — left as-is.
#6 tomography_reconstruct/solve: MEASURED-NULL — 47.5 μs (16 links) /
60.4 μs (32 links) for a full 50-iter ISTA solve; the 2 per-solve voxel
buffers (~4 KB) are negligible vs O(iters·links·voxels) compute, and
reconstruct(&self) reuses them across iterations already — left as-is.
#7 pose_kalman_update/cycles: MEASURED-NULL — 150 ns (17 kpts) / 2.82 μs
(170); the Kalman "gain matrices" are fixed-size STACK arrays
([[f32;3];6]), zero heap — nothing to reuse — left as-is.
#8 field_model_occupancy (eigenvalue feature): MEASUREMENT-ONLY — quantifies
the per-call n×ばつn eigendecomposition cost; incremental SVD is a sized
future project, not attempted (number recorded in ADR-154 §7.4).

Reproduce:
cargo bench -p wifi-densepose-signal --no-default-features --bench dsp_perf_bench
cargo bench -p wifi-densepose-signal --bench dsp_perf_bench # adds #8

Cargo.lock: dev-dep (criterion/clap) graph + crate version bumps from the
build; no runtime-dependency change.

Changes:
feat(beyond-sota): ADR-155 metric unification + ADR-156 RaBitQ Pass-2 (honest negative + latent topk bugfix) (ruvnet#1053)

• refactor(train): hoist canonical PCK/OKS to un-gated metrics_core; fold test_metrics onto production (ADR-155 M1 §8)

ADR-155 §8 deferred item: test_metrics.rs reference kernels validated
production against their OWN reimplementation — a test that cannot catch a
canonical-impl bug (both could be wrong the same way).

• Extract canonical_torso_size / pck_canonical / oks_canonical / sigmas /
  bounding_box_diagonal into a new NON-tch-gated metrics_core module, so
  the single metric definition is reachable under
  cargo test --no-default-features (the metrics module is tch-gated).
  metrics re-exports every item → still exactly ONE implementation.
• Rewrite tests/test_metrics.rs to assert the PRODUCTION pck_canonical /
  oks_canonical equal hand-computed fixtures (not a reimplementation):
  canonical_pck_matches_hand_computed_fixture (corr=3/total=4/pck=0.75),
  hip↔hip normalizer pin, zero-visible⇒0.0, OKS perfect⇒1.0, fake-Gold pin.
• Keep an INDEPENDENT raw-threshold reference kernel only as a differential
  cross-check: test_kernel_agrees_with_canonical asserts it AGREES with
  canonical where torso==1.0 (genuine cross-check, not duplication).

Grade: MEASURED. test_metrics 10→12 tests, 0 failed.

• fix(sensing-server): relabel divergent live PCK/OKS so they're never conflated with canonical (ADR-155 M1 §2.1/§8 Goal C)

Goal C named training_api.rs:804 (torso-HEIGHT PCK). Auditing it surfaced
TWO findings the ADR-155 §1 table missed:

1. training_api.rs is an ORPHAN file — not declared mod in lib.rs OR main.rs,
   so it does NOT compile into the crate. It does not drive the live server.
2. The REAL live best_pck/best_oks (main.rs training path → RVF metadata
   JSON read by model_manager.rs) come from trainer.rs:
   • pck_at_threshold = RAW-threshold PCK, NO torso normalization (the most
     divergent kind), printed/serialized as bare "PCK@0.2".
   • oks_map calls oks_single(area=1.0) = the EXACT fake-Gold pattern
     ADR-155 §2.1 claimed closed elsewhere — still live here, inflating best_oks.

Resolution = RELABEL (torso/raw math is load-bearing on different data; the
pub fns can't be renamed without breaking API; sensing-server has no train/
ndarray dep). Honest unify is a tracked §8 backlog item.

• training_api.rs: compute_pck → compute_pck_torso_height + divergence doc;
  val_pck/best_pck/val_oks struct fields documented as torso-HEIGHT proxies;
  logs say pck_torso_h@0.2. Test torso_pck_is_labelled_distinctly_from_canonical.
• trainer.rs (LIVE): pck_at_threshold documented raw-unnormalized; oks_map
  area=1.0 flagged fake-Gold; test pck_at_threshold_is_raw_unnormalized_not_canonical.
• main.rs: live print relabelled pck_raw@0.2 / oks_map(area=1.0 proxy).

No wire-format field renames (back-compat); no pub-API rename (no silent break).
Grade: MEASURED (relabel + divergence pinned). sensing-server 450→451 lib tests, 0 failed.

• Honest finding: §1's "seven divergent metrics" was an UNDER-count —
  sensing-server's LIVE trainer.rs has a raw-unnormalized PCK and an

• feat(ruvector): RaBitQ Pass-2 randomized rotation + topk bugfix (ADR-156 §8)

Implements the deferred "Multi-bit / Extended RaBitQ Pass 2" backlog item
from ADR-156 §8: a deterministic randomized orthogonal rotation applied
before sign-quantization, the published RaBitQ construction (Gao & Long,
SIGMOD 2024).

Rotation construction: Fast Hadamard Transform + seeded ±1 sign flips
("HD" / randomized Hadamard), O(d log d) time and O(d) memory — a dense
d×ばつd rotation is O(d2) and infeasible at the 65,535-d the wire format
provisions for. Pads to the next power of two; SplitMix64 seeds the sign
stream so index-time and query-time rotations are bit-identical.

API is additive and backward-compatible: Pass 1 (from_embedding) is
untouched; Pass 2 is opt-in via Sketch::from_embedding_rotated and
SketchBank::with_rotation (+ insert_embedding / topk_embedding /
novelty_embedding helpers that rotate consistently). Default behaviour
is unchanged.

While building the Pass-2 coverage harness, found and fixed a PRE-EXISTING
correctness bug in SketchBank::topk: the n>k heap path used
BinaryHeap<Reverse<(d,id)>> (a min-heap) but treated its peek as the
max, so it returned the k FARTHEST sketches as "nearest". The shipped unit
tests only exercised the n≤k fast path, so it went unnoticed. Fixed to a
plain max-heap; pinned by topk_heap_path_returns_nearest and
tight_clusters_give_high_coverage_with_overfetch (the latter measured
0.072 on the old code).

New tests (+17, 100→117 in the crate): rotation determinism/norm-preservation
(rotation_is_deterministic_for_seed, rotation_preserves_norm), Pass-2
shape-compatibility, pass2_coverage_not_worse_than_pass1, and a
deterministic coverage report.

MEASURED top-K coverage (anisotropic planted-cluster fixture, cosine ground
truth; dim=128 N=2048 K=8 64 clusters noise=0.35 128 queries):
candidate_k=K=8 : Pass1 36.13% -> Pass2 46.39% (both << 90% bar)
candidate_k=24 : Pass1 83.89% -> Pass2 91.60% (Pass2 clears 90%)
candidate_k=32 : Pass1/Pass2 100%
Honest result: rotation consistently helps (+10pp at strict K), but neither
pass clears the ADR-084 90% bar at candidate_k==K on this distribution.
Pass 2 reaches 90% only with ~3x over-fetch (the ADR-084 "candidate set"
deployment pattern). Multi-bit Pass 3 evaluated separately.

• feat(ruvector): multi-bit Pass-3 experiment + ADR-156/084 measured results

Adds the multi-bit half of the ADR-156 §8 "Multi-bit / Extended RaBitQ"
item as a MEASURED experiment (coverage::measure_multibit): rotate, then
b-bit uniform scalar-quantize each coord, rank by L1 over codes — the
natural multi-bit generalization of hamming. Measures the bit/coverage
tradeoff the backlog item asked for.

MEASURED at the strict bar (candidate_k=K=8, anisotropic planted-cluster
fixture, cosine ground truth):
Pass1 (1-bit, no rot) 36.13% 16 B/vec
Pass2 (1-bit, rot) 46.39% 16 B/vec
Pass3 (rot, 2-bit) 54.39% 32 B/vec
Pass3 (rot, 3-bit) 66.70% 48 B/vec
Pass3 (rot, 4-bit) 74.22% 64 B/vec
Honest: multi-bit monotonically helps but even 4-bit (4x memory) reaches
only 74% at the strict bar — neither rotation nor <=4-bit multi-bit clears
the strict-K 90% bar on this distribution. The bar is met via over-fetch
(Pass2 @ candidate_k=24). Tests: multibit_tradeoff_report,
multibit_1bit_matches_pass2_approx (+ sanity that 1-bit ~= Pass-2).

Docs:

• ADR-156 §8 item #2 marked RESOLVED-PARTIAL; §5 #2 grade CLAIMED ->
  MEASURED-on-our-hardware; new §10 with full measured tables, the topk
  bugfix disclosure, and graded deferred sub-items.
• ADR-084: "Pass 2" section answering the rotation open-question with
  measured numbers + the topk bug note.
• CHANGELOG [Unreleased]: Added (Pass-2 milestone) + Fixed (topk heap).
