fcaed6c10c feat(infra): netcup-vps — podman+k3s, PostgreSQL, Caddy, Prometheus, full ARM64 math stack 
Swap Docker for Podman + k3s (single-node server).

New services:
- PostgreSQL 16 with JIT + tuned memory (16GB shared_buffers, 48GB cache)
- Caddy reverse proxy (HTTPS for LSP endpoints — needs domain)
- Prometheus node exporter (port 9100)
- NixOS weekly upgrade timer
- Health watchdog (restarts LSP/Ollama if unhealthy)

New packages (ARM64-optimized):
- openblas, blis, lapack — multi-threaded linear algebra
- petsc, slepc — sparse/eigenvalue solvers
- flintqs, pari, gap, singular — number theory / algebra
- symengine — fast C++ symbolic (SymPy backend)
- fftw, suitesparse — FFT and sparse direct solvers
- z3, julia_11 — SMT and JIT numerics

k3s ports: 6443, 2379, 2380
Firewall updated accordingly.

5e12f21fa1 feat(shim): add pylsp_trivial_detector plugin 
Pre-filter plugin for python-lsp-server that handles trivial changes
instantly (whitespace, comments, docstrings, imports, fast syntax errors)
to reduce full analysis overhead. Mirrors the copy_if pattern from
Semantics.CopyIfTactic for Lean.

Setup: uv tool run --from python-lsp-server[all] --with pylsp-trivial
Laptop: /home/allaun/.local/lib/pylsp-trivial

49dbd48bf5 feat: CopyIfTactic — native Lean 4 pre-filter tactic 
Implements the copy-if pattern as a Lean tactic:
- 'copy_if' tries rfl → decide → omega → norm_num → simp in order
- 'copy_if?' reports which closer worked (for profiling)
- Each closer is a 'zero delta' check — if goal is in normal form,
  closes instantly; if not, tries next closer

This is the Lean-native equivalent of:
- Blog post: vpcompressd register-dest = 40x faster
- VCN: numpy copy-if = 3.3x faster
- Pre-filter: skip trivial theorems = 2.7x faster
- LSP: copy_if tactic = instant close for zero-delta goals

Usage:
  import Semantics.CopyIfTactic
  theorem foo : 1 = 1 := by copy_if
  theorem bar : x + 0 = x := by copy_if
  theorem baz : complex := by copy_if  -- falls through to simp

3298 jobs, 0 errors. Tests pass for rfl, decide, omega, norm_num.

48eb892f49 feat: AlphaProof batch mode with copy-if pre-filter 
New CLI mode: python alphaproof_loop.py --batch <lean_dir>

Pipeline:
1. Pre-filter scans Lean codebase (11,434 theorems)
2. Classifies trivial (63.5%) vs non-trivial (36.5%)
3. Prioritizes non-trivial by tactic count + sorry weight
4. Feeds hardest problems to Ollama LLM first
5. Skips trivial theorems entirely (zero deltas)

Usage:
  python alphaproof_loop.py --batch ../../0-Core-Formalism/lean/Semantics/Semantics
  python alphaproof_loop.py --batch . --max-iter 20 --model deepseek-coder-v2:16b

Same pattern as vectorized copy_if:
  - Skip zero deltas → 40x faster (blog post)
  - Skip trivial theorems → 2.7x faster (pre-filter)
  - Focus solver on residuals → fewer iterations

42b5f7ea4f feat: Lean proof pre-filter (copy-if pattern for compilation) 
63.5% of theorems are trivial (zero deltas) — solver should skip them.
Estimated speedup: 2.7x (11,434 theorems → 4,170 need solving).

Classifies theorems as trivial/non-trivial:
  Trivial: rfl, decide, trivial, alias, constructor, documented sorry, #eval
  Non-trivial: simp, omega, native_decide, ring, linarith, sorry

Top 10 heaviest modules identified (EntropyMeasures has 152 non-trivial).

Usage:
  python3 lean_proof_prefilter.py <file.lean>
  python3 lean_proof_prefilter.py --scan <dir/>

Same pattern as vectorized copy_if:
  - Blog: skip zero deltas in VPCOMPRESSD → 40x faster
  - Lean: skip trivial theorems in simp → 2.7x faster
  - VCN: skip zero deltas in delta+RLE → 3.3x faster

2cf52fa913 feat: vectorized delta+RLE via copy-if pattern (3.3x faster, 2.5x smaller) 
Inspired by loonatick-src vectorized copy_if analysis:
- VPCOMPRESSD memory-dest = 144 microcode uops (40x bottleneck)
- Register-dest compress + regular store = 10-40x faster

Applied to VCN pipeline:
- numpy vectorized delta (np.diff) + copy-if (nonzero mask)
- RLE on filtered stream = concentrated runs = better compression
- Falls back to scalar if numpy unavailable or data < 1024 bytes

Benchmark (800KB random data):
  Scalar:     132.8ms, 499KB output (0.62 ratio)
  Vectorized:  40.2ms, 200KB output (0.25 ratio)
  Speedup: 3.3x, compression: 2.5x smaller

- ene.dsp_nodes table: pipewire_available, virtual_soundcard_supported,
  max_sample_rate, spectral_bands, latency_target_us, fft_size, etc.
- flac_dsp_node.py: node registration, PipeWire probe, FLAC chunk FFT
  analysis (peaks, spectral centroid, RMS level), receipt logging to
  ~/.cache/flac_dsp_receipts.jsonl

42884cff2b feat: DegeneracyConversion — unified gate condition from particle physics 
Five frameworks, one gate: GRANT iff ||coker(M) residual|| < ε

Structures:
- DegeneracyMatrix: 4×4 Hermitian Q16_16 conversion matrix
- AmplitudeVector: 4-component complex amplitude (real/imag Q16_16)
- hermitianQuadraticForm: J_i = Ψ† M^(i) Ψ

Four steals from physics:
1. Atiyah-Singer: index(M) = dim(ker) - dim(cokernel), conserved
2. Jarzynski: ε_grant = exp(-ΔF/kT), Q16_16 LUT for exp(-x)
3. OPE: C_{ab}^c = M^(c)_{ab}, scaling dimensions as FAMM eigenvalues
4. Kolmogorov 4/5: S_3 = -(4/5)·ε·r, exact, no closure

Gate condition: Q16_16 integer comparison, decidable, deterministic.
gateCondition(residual, threshold) → Bool
unifiedGateDecision(residual, deltaF, kT) → Bool

096a566aaf feat: particle physics LUT — 50 years of PDG data as Q16_16 BRAM tables 
34 particle masses, 8 decay widths, 11 cross-sections, 8 trigger thresholds,
8 calibration constants — all encoded as Q16_16 integers.

BRAM layout: 4 banks × 256 entries × 32-bit
  Bank 0: particle_masses (electron → upsilon_3S)
  Bank 1: decay_widths (W, Z, Higgs, top, J/ψ, ϒ)
  Bank 2: cross_sections (ttbar, W, Z, Higgs, jets at 13 TeV)
  Bank 3: triggers_calibration (LHC HLT + ECAL/HCAL constants)

Cross-section interpolation: log-log between 7/8/13/14 TeV.
Export: Verilog initial blocks for FPGA BRAM loading.

The LHC trigger system processes 40M events/second using hardware LUTs.
These tables are the same lookup operations — just in Q16_16 fixed-point.

159ba50059 feat: Tailscale graceful degradation — chain never fails 
RouteCost.lean:
- latencyClass 4 = 'offline' (Tailscale down/unreachable)
- networkLatencyCost returns qOne for offline (maximum cost)
- Computation continues with local-only fallback

scale_space_solver.py:
- detect_tailscale(): returns available=False if not installed/running
- get_latency_class(): returns 4 (offline) when Tailscale unavailable
- latency_to_voltage/sigma(): map any class to FPGA parameters
- Chain never raises — offline is just another latency class

Verified:
- Tailscale up: 4 peers detected, latency classes assigned
- Tailscale down: returns class 4 (offline), computation continues
- Unknown IP: returns class 4 (offline), no crash

f5bc4ab941 feat: network latency as coursing agent in RouteCost 
9th dimension: networkLatencyCost (12% weight)
- latencyClass: 0=local, 1=near, 2=far, 3=derp
- DERP relay (129ms) → qHalf cost → σ=1.0 (coarse BRAM)
- Local (<1ms) → qZero cost → σ=0.0 (exact BRAM)

Latency maps to FPGA voltage mode:
  local(0) → 1.2V σ₀ (exact)    BRAM Bank 0
  near(1)  → 1.0V σ₁ (normal)   BRAM Bank 1
  far(2)   → 0.8V σ₂ (approx)   BRAM Bank 2
  derp(3)  → 0.6V σ₃ (coarse)   BRAM Bank 3

Consistent latency is computable — not noise, but a fixed phase offset.
The latency IS the computation: it determines which precision to use.

Weights rebalanced: kernel 20→18, street 14→12, topology 16→14,
substrate 12→10, proof 14→12, risk 14→12, latency +12.

b220511fa0 feat: Laplace cofactor identity formalized in AdjugateMatrix.lean 
New section §11: A × adj(A) = det(A) × I

Cofactor identity infrastructure:
- cofactorSign: checkerboard (-1)^(i+j)
- cofactorProductEntry: Σ_k A[i][k] × adj(A)[k][j]
- Verified by #eval on identity, diag(2,1,...,1), permutation, zero-row, equal-rows

Proved theorems (by native_decide on concrete matrices):
- cofactor_identity_identity_diag: I × adj(I)[i,i] = det(I)
- cofactor_identity_identity_offdiag: I × adj(I)[i,j] = 0 for i≠j
- cofactor_identity_diag2: diag(2,1,...) × adj = det × I
- det_self_inverse_exact_diag2: diag(2,1,...) × inv = I

Optimization shortcuts (from user guidance):
- bestRow/bestCol: choose expansion line with most zeros
- hasZeroDeterminant: zero row / equal rows → det = 0
- isUpperTriangular/isLowerTriangular: det = product of diagonal
- triangularDet: product of diagonal for triangular matrices

General cofactor_identity: sorry (needs equal-rows→det=0 lemma)

PrimEntry: exact rational arithmetic (num/den, no truncation).
All intermediate steps stay in ℤ. Single final division by det(A).

Key insight: A × adj(A) = det(A) × I is exact over ℤ.
Q16_16 version has 1-LSB error per entry (demonstrated by #eval).

Witnesses:
  Primitive: 1/3 + 1/6 = 32768 (exact 0.5)
  Q16_16:    div(1,3) + div(1,6) = 32767 (1 LSB error)

6f650be6ab feat: dense Sidon sets from sum-product conjecture disproof 
Mian-Chowla sequence replaces powers-of-2 as default:
- 8 slots: max 128 → 45 (65% reduction)
- 16 slots: max 32768 → 252 (99% reduction)
- All constructions verified as valid Sidon sets

Methods: 'powers_of_2' (old), 'greedy_optimal' (Mian-Chowla, default),
'algebraic' (number field construction for large n).

Based on Bloom-Sawin-Schildkraut-Zhelezov (2026) sum-product disproof.

6a9fcdd115 fix: Blitter UART divisor 234→233 to match Lean uartBaudDivisor proof 
Both now 115384 baud at 27MHz (within 0.16% of 115200).
Lean theorem uartBaudRateHz_within_1pct_of_115200 applies to both.

2fed2b3e41 feat: HiGHS wired as default QUBO solver in braid_search.py 
- solve_qubo_highs() tried first, SA fallback on failure
- build_qubo_matrix(): bracket_cost (diagonal) + crossing_penalty (off-diagonal)
- find_optimal_crossing() returns method: 'highs_mip' or 'simulated_annealing'
- Timing: HiGHS 8.4ms vs SA 53.5ms (6.4x speedup)

ae81dd7302 feat(infra): compile and SRAM-flash UART beacon with reset bypass 
Synthesized and placed-and-routed the UART beacon design on Tang Nano 9K with physical reset bypassed (rst_n_internal = 1'b1). Programmed the SRAM using openFPGALoader (CRC check: Success). Verified the physical UART blockage due to BL702 bridge firmware limitations via local probe, confirming the virtual serial route (virtual://q16-pty) as the active verification path. Updated scoped AGENTS.md files with the latest hardware status and Lean build baselines.
