k3s-edge.nix:
- Added 'ca https://acme-v02.api.letsencrypt.org/directory' to porkbun_tls snippet
- Forces production LE instead of staging
fix-racknerd-tls.sh:
- Checks current Porkbun keys (redacted)
- Verifies production LE CA is configured
- Provides deploy and restart instructions
- Documents how to update Porkbun API keys via sops
- Added lean-proof skill auto-load requirement to Ground Rules
- Added no-Float rule to Ground Rules (front and center)
- lean-proof skill has trigger_patterns for auto-activation
- lean-autoformalization and vcn-compute-substrate also have triggers
- 6 hub skills installed (fpga, systemverilog, verilog-design, math-help, physics-intuition, hardware-counters)
- MCP4EDA registered as MCP server
Blitter6502OISC_small.v:
- Added uart_sent flag to prevent UART retransmission
- Verified via Verilator: UART sends exactly one byte on halt
- Test byte: 0xAA (recognizable pattern)
research_stack_top.v:
- Auto-start logic (100ms after reset, no button needed)
- LED shows heartbeat when CPU running, register values on halt
research_stack_tangnano9k.cst:
- uart_tx=17, uart_rx=18 (matches Sparkle reference design)
Simulation results (Verilator):
- uart_test.v: 115 bytes in 300K cycles (continuous TX verified)
- research_stack_top: UART fires after Blitter halt, 0xAA byte sent
- LED pattern changes from IDLE to RUNNING to HALTED
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)
Restored det_self_inverse theorem (removed by subagent).

HyperbolicStateSurface.lean:
- ko_preserves_hyperbola_approx: added TODO(lean-port) with proof sketch
- Requires sqrt squaring bound lemma for Q16_16
AdjugateMatrix.lean:
- det_self_inverse_approx: bounded-error variant (m×inv ≈ I within ε)
- det_self_inverse_exact: exact variant with division/multiplication preconditions
- Both have TODO(lean-port) with full proof sketches

Restructured the det_self_inverse theorem in AdjugateMatrix.lean into det_self_inverse_approx and det_self_inverse_exact to account for fixed-point division/multiplication truncation errors. Proved the updated build in Semantics.

The exact det_self_inverse theorem is NOT provable over saturating Q16_16
due to integer truncation in div/mul. Documented with concrete counterexample
(diag(3,1,...,1) gives 1 LSB error).
Proven base case: det_self_inverse_identity (identity matrix, native_decide).
The exact version requires either:
(a) Bounded-error variant (each entry within 1 LSB of I)
(b) Precondition: det divides all cofactor products exactly
(c) Proof over ℚ via Mathlib matrix library
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.
Resolve issue where build_sparkle_tangnano9k.sh failed to locate nextpnr-himbaechel by checking the system PATH when local folder tools/ is empty.
Build: 3571 jobs, 0 errors (lake build)
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.

- Add LyteNyte Grid cluster dashboard (React + FastAPI + k3s)
- Real-time telemetry: GPU util/VRAM/temp, CPU/memory, pod counts,
Tailscale connectivity, OS/kernel info for all 5 cluster nodes
- WebSocket live updates every 3s, dark theme, virtualized grid
- k3s deployment with hostNetwork, NodePort 30820, SSH-based collectors
- Backend uses /proc/stat + /proc/meminfo for portable NixOS metrics
- Tailscale status via SSH to host (container doesn't run tailscaled)
- Fix vcn_compute_substrate.py indentation (lines 45-269 had 1 extra
leading space). Script now compiles and runs encode/decode/receipt.
Build: py_compile OK, npm build OK, podman build OK
- Revert builder image in embedded_surface Dockerfile to rust:bookworm for glibc compatibility with bookworm-slim runner.
- Replace racknerd-surface.json Git LFS pointer with the actual retrieved JSON config to resolve parse errors.
- Separated and imported regenerated docker images for stubs and credential-server on all cluster nodes.
- Fixed Ingress resources and middleware to target the correct authentik-server service name.
- Rewrote verification script checks to handle iptables-based ports and relative redirects robustly.
- Updated nixos-laptop IP in node topology documentation.

abs_triangle: reverted to admit. The q16Clamp applies Int.abs internally, making
sign analysis after division non-trivial. Attempted proofs using Int.sign,
Int.sign_mul_abs, Int.ediv_neg_pos_of_neg, Int.mul_ediv_le all failed (missing
theorems in this Mathlib version).
Key theorem: mul_mono_left and mul_mono_right are proved and working.
Build: 3313 jobs, 0 errors (lake build)
FixedPoint.lean:
- mul_mono_left: proved via Int.mul_le_mul_of_nonneg_right + Int.ediv_le_ediv
with explicit hpos : 0 < q16Scale proof (not synthesized by norm_num)
- mul_mono_right: proved via Int.mul_le_mul_of_nonneg_left + same pattern
- abs_triangle: reverted to admit — q16Clamp applies Int.abs internally making
sign analysis non-trivial; needs case split on sign of (a*b)/q16Scale
SSMS.lean:
- t2 (line 617): corrected first arg from cT i - cT j to Q16_16.abs (cT i - cT j)
to match available hcand hypothesis
- t1 (line 606-614): fixed admit in inner proof with proper h_diff_nonneg +
lt_of_ge_of_le chain using h_aciBound_nonneg
- AGENTS.md: updated status — mul_mono_left/right are proved, abs_triangle is the
critical remaining blocker for aciPreservedByMlgruStep
Build: 3313 jobs, 0 errors (lake build)
FixedPoint.lean: add stubs for abs_triangle, sub_eq_add_neg,
mul_mono_left/right, add_le_add, abs_nonneg, abs_mul_le.
All blocked by the same core issue: calc/rw/omega fail on
ofRawInt-projected Int arithmetic after unfold mul/add/abs/neg.
The pattern that works in PistSimulation (unfold + Int.ediv_le_ediv
+ ofRawInt_toInt_eq_clamp + q16Clamp_monotone) fails here
because the goal structures differ.
Known-working pattern to finalize:
1. unfold the Q16_16 op
2. have h2 := raw Int inequality (Int.mul_le_mul_of_nonneg_*)
3. have hdiv := Int.ediv_le_ediv (by norm_num) h2
4. rw [ofRawInt_toInt_eq_clamp, ofRawInt_toInt_eq_clamp]
5. exact q16Clamp_monotone _ _ hdiv
