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) (#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)

  • 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)

  • 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.

  • 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

  • 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.

  • 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.

  • 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.
