Prove the analytic matmul-algebra core in verified Lean (Mathlib over ℝ +
core-Lean shape model), promoting matmul-kernel-v1 from L3 to an HONEST L4
(3 Lean-proved + 2 genuinely-N/A = 5/5, per strict leveling proved>0 &&
proved+na>=total).
Analytic obligations PROVED (sorry-free, `lake env lean <file>` exit 0):
- Output shape correctness → Theorems/MatMul/Shape.lean
matmul_output_shape (shape(A@B)=(rows A,cols B)) + matmul_output_len
(result buffer length = m*n, the contract postcondition), core Lean
- Matmul associativity → Theorems/MatMul/Associativity.lean
matmul_assoc ((AB)C=A(BC)), Mathlib Matrix.mul_assoc
- Matmul distributes → Theorems/MatMul/Distributivity.lean (new)
matmul_left_distrib / matmul_right_distrib, Mathlib mul_add/add_mul
Supporting matmul algebra also proved (strengthens the core, not counted twice):
- Theorems/MatMul/TransposeMul.lean (AB)ᵀ = BᵀAᵀ (Matrix.transpose_mul)
- Theorems/MatMul/MatVecLinearity.lean A(x+y)=Ax+Ay, A(c·x)=c·Ax
(Matrix.mulVec_add / mulVec_smul)
- Theorems/MatMul/Identity.lean A·I=A=I·A (pre-existing)
Genuinely NOT-APPLICABLE (runtime/empirical, l4_not_applicable=2):
- "SIMD matches scalar" — IEEE-754 FMA-ordering ULP equivalence (≤4 ULP)
between AVX2 and scalar paths on real hardware (Kani + FALSIFY-MM-003)
- "Quantized error bounded" — int8-rounding bound |q_dot − f32_dot| over
concrete rounded data (Kani verify_quantized_dot_bounded + FALSIFY-MM-004)
Contract-only + Lean-only change; binding.yaml untouched (proposed bindings
returned as data, both fns grep-confirmed to exist).

…g proofs in verified Lean Proves the analytic core of the token-sampling contract in Lean 4 (0 sorry): - TemperatureScaling: temperature scaling by t>0 is order-preserving, so it preserves the argmax (greedy = t->0+ limit) and pairwise logit ordering. - TopK (structural): kept tokens strictly dominate dropped tokens; top_k=0 keeps all (no filter); top_k=1 keeps exactly the argmax (== greedy). - RepeatPenalty: penalty 1.0 is the identity; any penalty >= 1 never increases a repeated token's logit. The remaining 4 obligations are GENUINELY-NOT-APPLICABLE to a real-number proof and stay enforced by falsification tests: - seed bit-determinism across process runs (runtime/empirical) - finite-temperature NaN/inf rejection (IEEE-754; ℝ has no NaN/inf) - RNG unit draw in [0,1) (IEEE-754 f32 rounding exactness) - error paths exit non-zero (runtime CLI process behaviour) verification_summary: 3 lean_proved + 4 not_applicable == 7 total => L4 (strict).

…notonicity in verified Lean (honest L3)
Climb gelu-kernel-v1 by discharging its analytic proof obligations in
sorry-free Lean, reusing the prior-wave tanh-approximation GELU definition
(ProvableContracts.Gelu.gelu) and GeluZero.
Proved (0 sorry), verified via 'lake env lean':
- Non-negativity for positive inputs -> Gelu.gelu_nonneg_of_pos
x>0 ⟹ (0.5·x)≥0 and (1+tanh g(x))>0 (Real.neg_one_lt_tanh) ⟹ ≥0.
- Monotonically increasing for positive inputs -> Gelu.gelu_strictMono_of_pos
0<y<x ⟹ both GELU factors positive & strictly increasing (cube strictMono
via Odd.pow_lt_pow; tanh strictMono from sinh(β−α)>0) ⟹ GELU(y)<GELU(x).
- (reused) GELU(0)=0 -> Gelu.gelu_zero; plus sign behaviour gelu_nonpos_of_neg.
Honest classification of the 5 proof_obligations:
proved (2): non-negativity, positive monotonicity
N/A (1): SIMD-vs-scalar ULP equivalence (runtime/hardware, not algebraic)
uncovered analytic (2): odd-symmetry CDF→step limit; tanh-approx-vs-erf 0.005
bound (needs unformalized erf + interval reasoning). Left UNPROVEN, not
faked N/A, so the contract stays HONESTLY L3 (2+1=3 != 5).
Files: Defs/Gelu.lean, Theorems/Gelu/{GeluZero,GeluSign,GeluMono}.lean
(Defs/Gelu.lean + GeluZero.lean reused verbatim from prior wave).

Proves 3 of 5 analytic proof-obligations of conv1d-kernel-v1 sorry-free in
Lean 4 (Mathlib-backed) over a List/Signal convolution model:
- Output shape correctness: conv1d_valid_length_eq_outLen (List.length = L_out)
- Convolution linearity: conv_linear (exact eps=0 real identity; + conv_add/smul)
- Output bounded: conv_abs_le (|y[n]| <= K·max|w|·max|x|)
Bonus corroborating theorems: conv_shift_eq (shift-equivariance) and
conv_zero_eq (zero-input ⇒ zero-output).
The remaining 2 obligations are genuinely N/A at L4: im2col-GEMM implementation
equivalence (1e-6 FP, FALSIFY-CV-003) and SIMD-vs-scalar 8-ULP (FALSIFY-CV-004)
— both runtime/IEEE-754 properties, not analytic identities. 3 proved + 2 N/A

Faithful model of the real apr_dtype_to_ggml enum ids, not a vacuous rfl. → honest L3 (strengthened, not faked): - activation-kernel-v1: ReLU non-neg/idempotency, LeakyReLU, GELU bounds proved (9 of 11); 1 obligation left analytic-unproven (not N/A) → correctly L3.

PILLAR-2 scaled dot-product attention (1/√d_k). Discharge 6 of 7 analytic
proof obligations in verified Lean (zero sorry), reusing the sovereign Softmax
defs. Contract honestly stays L3 (not a manufactured L4) because the 7th
obligation is analytic-unproven, not N/A.
Proved (ProvableContracts/Theorems/Attention/Scaling.lean):
- Score shape correctness → scaledScores_apply (Matrix (Fin n)(Fin m) ℝ entry)
- Variance preservation → variance_smul (Var(c·x)=c²Var x) +
variance_scaled_by_inv_sqrt_normalizes (Var(s/√d)=1)
- Score bound with QK-norm → scaled_score_abs_le_sqrt (Cauchy–Schwarz |q·k/√d|≤√d)
- Attention entropy ≥ 0 → attention_entropy_nonneg (negMulLog ≥ 0 on [0,1])
- Attention entropy ≤ log m → attention_entropy_le_log_card (Jensen vs concave log)
- Max-subtraction equiv. → softmax_max_subtraction_invariant (reuse shift_invariance)
Left analytic-UNPROVEN (keeps contract at honest L3, NOT marked N/A):
- Scaling prevents saturation: H(softmax(QKᵀ/√d_k)) > H(softmax(QKᵀ)) — strict
monotonicity of softmax entropy in temperature (dH/dT>0). Genuine analytic
claim, deep derivative proof; deliberately not faked as N/A.
verification_summary: total=7, l4_lean_proved=6, l4_not_applicable=0, sorry=0.
proof-status: L3, lean 6/7 (was 0). Verified: `lake env lean Scaling.lean` exit 0,
grep -E '\bsorry\b|\badmit\b' → none.

Fixes #751. Vector-matrix multiplications (m=1 or n=1) are completely memory bandwidth bound. Dispatching them to WGPU incurred massive buffer copy overhead per-token. This fallback allows the CPU to process these ops using its shared memory bandwidth, eliminating the PCIe/dispatch bottleneck on M1 Max.

…print Incorporates the cross-pillar direction from the 2026-07-05 Fable architectural review (#2292) into the live autonomous campaign. - docs/specifications/roadmap-next-wave-2026-07-05.md: EV-ordered sprint plan mapping the review's 18-item backlog across P1-P5 + infra. Direction shift: enforcement-integrity FIRST (ranks 1-7 are gate-integrity/anti-theater), new beats second. Grounded by a 5-agent workflow (wf_103658cf-4d2): 21/23 claims CONFIRMED_STILL_TRUE on the current tree; all 18 items actionable. Host assignment across the 4-silicon fleet + the single-line ci.yml:317 consolidation constraint. - docs/roadmaps/roadmap.yaml: +16 net-new items (ranks 1,3,4,5,6,7,9,10,11,12,13,14,15,16,17,18) as planned/blocked entries, each carrying a RED-turning mutation; -152 ANSI-corrupted "inprogress" entries (id = captured "\e[36m..." color escape, all-null payload) -> inprogress restored to 0 (#2275 target). 595 legitimate entries preserved byte-for-byte; 611 items, 0 dup/corrupt ids.

…est init (unblocks #2286 workspace-test) The CRUX-M1 --ollama-compat merge (#2296) added `ollama_compat` to the ServeCommands::Run variant, but the lib_parse_rosetta.rs:250 test initializer was not updated — E0063 broke `cargo nextest --lib` (the parallel build-fix commits missed this lib test). cargo test --workspace --lib --no-run now green. Also folds 3 issue-triage-surfaced untracked items into roadmap.yaml: SPEC-DIST-393-GPU-BACKEND (#393), M-GPU-MOE-2-WGPU-FORWARD (#1582), M-GPU-MOE-3-Q8K-THROUGHPUT (#1583/#1838).

…behavior (unblocks #2286) build_distributed_config_role_is_unsupported asserted the coordinator role errors with "unreleased entrenar" — but PR #2294 (issue #393) implemented distributed config, so the coordinator role is now SUPPORTED and validates params. With no --bind it returns ValidationFailed("--bind is required for coordinator role"), not the old unreleased-feature rejection. Renamed to build_distributed_config_coordinator_requires_bind and assert the bind-required message. Verified: `cargo test -p apr-cli --lib build_distributed_config` → 2 passed.
