- e8_singer_improvement: proven via Singer set as direct witness; (119/120)^k ≤ 1 by
pow_le_one₀, bound follows from mul_le_of_le_one_right.
- erdos30_e8_conditional: proven via interval_sidon_exists (Singer's theorem bridge);
C=1/4, Nat.sqrt ↔ Real.sqrt bridge via nlinarith on squared terms.
- sidon_weight_bound: restated — LHS corrected from σ₃(a+b) sums to σ₃(a)·σ₃(b)
products over unordered pairs (original was INVALID_STATEMENT; E₈ convolution
identity delivers products, not values at pair-sums). Remains ANALYTIC_OPEN.
- e8_levelset_density: restated — T fixed to N^4 (fixed T refuted by
e8_levelset_density_fails; σ₃(n) ≤ n·n³ = n^4 ≤ N^4 for n ≤ N). Fixed base
typo Nat.log N → Nat.log 2 N. Remains ANALYTIC_OPEN sorry.
- §14 summary updated with proven theorems and restatement notes.
- Add merkle_tensegrity_load_equation_generator.py to 4-Infrastructure/shim/
(required by cad_force_probe_experiment_matrix.py import).

This squashes all local history (768 commits) onto the scrubbed PR #90
baseline. Individual commits were lost during filter-repo corruption;
the working tree content is preserved intact.
Build: N/A (working tree state only)
Squash the four overlapping feature branches into a single change set against
main, eliminating cross-PR merge conflicts and the duplicated CI-fix scripts.
What this brings in (merge order #79 -> #80 -> #81 -> #89):
- #79 refactor(infra): shared utilities (4-Infrastructure/lib/*: q16, hashing,
jsonl, fraction_utils) + the scripts/math-first/* validators that the
math-check CI requires.
- #80 feat(lean): Semantics.E8Sidon (1025 lines) -- Eisenstein coefficient
identity E4^2 = E8 and the Sidon framework. E4_sq_eq_E8_coeff is fully proved
(all Fourier-coefficient extraction machine-checked); the single residual gap
is pinned to E4_sq_eq_E8_qExpansion (Mathlib lacks the valence formula /
dim M8 = 1). 4 sorries + 1 axiom (e8_additive_completeness), all TODO(lean-port).
- #81 refactor(lean): Float-free FixedPoint core (integer-only sqrt/log2/expNeg).
E8Sidon.lean kept at #80's final 1025-line version (the #81 intermediate
438-line copy was overridden by merge order).
- #89 feat(lean): Semantics.RRC.PolyFactorIdentity -- short-sleeve polynomial
detection at the zerocopy limb boundary; now imports Semantics.E8Sidon for
sigma3/sigma7/convolutionLHS (single source of truth) instead of inlining them.
Conflict resolution:
- flake.nix -> canonical rs-surface removal (Garnix shutdown).
- scripts/math-first/* -> byte-identical across branches, clean.
- .cursorrules / AGENTS.md -> unified; baselines + sorry inventory refreshed.
Verification:
- lake build (default aggregator): 3573 jobs, 0 errors.
- lake build Semantics.RRC.PolyFactorIdentity (E8Sidon + FixedPoint + PolyFactor):
3655 jobs, 0 errors. Witnesses verified (sigma7 4 = 16513, convolutionLHS 6 = 2350).
- Python tests: 68/68 pass.
Note: the "Workers Builds: researchstack" check is a preexisting external
Cloudflare build unrelated to this change (no branch touches 4-Infrastructure/cloudflare/).

* fix(security): remove hardcoded secrets, patch command injection, tighten CORS and Cypher guard
- run_import_workflow.py, run_multi_import.py: replace hardcoded budget
password with BUDGET_PASSWORD env-var (fail-fast if unset)
- server.js /ingest: replace shell-interpolated exec() with execFile()
so user-controlled title/body cannot inject shell commands
- authentik-values.yaml: blank out bootstrap_password and bootstrap_token
so they must be supplied at deploy time via --set or sealed-secret
- cluster-dashboard main.py: restrict CORS from allow_origins=["*"] to
env-configurable whitelist (default: dashboard.researchstack.info),
methods to GET, headers to Authorization+Content-Type
- neo4j_obsidian_connector_router.js (both copies): replace permissive
prefix-only readOnly regex with a deny-list that blocks
CREATE/MERGE/DELETE/DETACH/SET/REMOVE/DROP anywhere in the query, and
route readOnly queries through session.readTransaction()
Co-Authored-By: Allaun Silverfox <bigdataiscoming+9i37y6j2@protonmail.com>
* fix(security): add CALL procedure allowlist for Cypher readOnly, add OPTIONS to CORS
- Cypher guard: restore positive allowlist for CALL targets (only db.* and
apoc.meta.* allowed in readOnly mode). Extract cypherReadOnlyViolation()
helper for clarity. Both copies updated.
- CORS: add OPTIONS to allow_methods so preflight requests succeed.
Co-Authored-By: Allaun Silverfox <bigdataiscoming+9i37y6j2@protonmail.com>
* fix(security): use negative lookahead for CALL allowlist, remove dead CALL\s*\{ branch
- Replace two-regex CALL check with single negative-lookahead
CYPHER_CALL_DISALLOWED_RE = /\bCALL\s+(?!db\.|apoc\.meta\.)/i
This correctly blocks queries containing ANY disallowed CALL target,
even when bundled alongside an allowed CALL db.* or CALL apoc.meta.*.
- Remove dead CALL\s*\{ alternative from CYPHER_WRITE_RE — the trailing
\b never matched because { is a non-word character.
- Both copies updated identically.

Document discrepancies between the aspirational architecture (in the
flake/docs) and what's actually deployed. Covers control plane location,
edge Caddy divergence, Traefik port, cross-namespace services, and
hostname mismatches. Load the research-stack-infrastructure-bootstrap
skill for the actual deployment procedure.
Build: no build needed
- Change middleware address from authentik-server.services.svc.cluster.local
to authentik-server.authentik.svc.cluster.local (Authentik lives in
authentik namespace, not services)

Security:
- Move OPENID_CLIENT_SECRET from plaintext to K8s Secret ref
- Update manifest to use valueFrom.secretKeyRef
Cleanup:

Architectural plan for Tailscale mesh + Ray + VCN + compute surfaces.
5-layer stack:
1. Tailscale connects everything (WireGuard, DERP relay)
2. Ray schedules work across the mesh
3. VCN compresses data (50x bandwidth reduction)
4. FrameDispatcher routes by tag
5. Compute surfaces execute (GPU/CPU/Ethernet/framebuffer/MCU)
Key insight: every device in the Tailscale mesh is a potential
compute node. Framebuffer and Ethernet surfaces turn devices
that "cant run Ray" into compute participants.
4 phases:
1. Ray over Tailscale (mostly done)
2. Multi-tier scheduling (probe done, placement pending)
3. Framebuffer + Ethernet integration (host-side pending)
4. Edge devices (ESP32, 1-Wire sensors)
New tier between CPU_FFMPEG and FRAMEBUFFER:
GPU_CUDA(7) > GPU_VAAPI(6) > GPU_APU(5) > CPU_FFMPEG(4) >
ETHERNET(3) > FRAMEBUFFER(2) > ESP32(1) > RELAY(0)
- _detect_virtio_net(): probes /sys/class/net for virtio driver (0x1af4)
- PistPacket computation via TX/RX descriptor rings
- Host vhost-user backend does matrix transforms
- CRC32 hardware offload = witness verification
- Works in any VM with network (even without framebuffer)
ray_vcn_bridge.py: Ray transport for the VCN-LUPINE bridge.
Replaces GPUNodeConnection TCP/MKV transport with Ray ObjectRef.
FrameDispatcher, BraidBackend, CUDABackend are unchanged — only
the wire between daemon and GPU node changes.
- RayBraidBackend: compute actor matching VCNBraidBackend pattern
- RayCUDABackend: GPU actor with /dev/dri (Mesa, no NVIDIA plugin)
- RayVCNBridge: full bridge as Ray actor (replaces daemon)
- RayGPUNodeConnection: drop-in for GPUNodeConnection
- SyncBraidWrapper/SyncCUDAWrapper: bridge Ray actors to sync interface
STRAND 42B → 63B, CROSSING 42B → 22B, PIST 24B → 57B
Batch 10: 5ms (0.5ms/frame), 10/10 non-empty
- Add detection for integrated AMD graphics (APUs/iGPUs) based on hardware model name
- Configure UMA-friendly full-range yuvj420p format to reduce system memory bandwidth footprint by 50%

Hopf-Cole transformation maps Burgers to heat equation:
u = -2v * d(ln ψ)/dx
dψ/dt = v * d²ψ/dx² (exact via FFT)
Benchmark results:
N=512, v=0.01: 1.45x speedup
N=1024, v=0.01: 83.4x speedup
N=2048, v=0.01: 151.3x speedup
Key insight from adversarial review:
- RG assumption (nonlinear term vanishes) is FALSE
- But 1D Burgers IS integrable via Hopf-Cole
- Exact solution in O(N log N), no time stepping
- The 'insultingly easy' regime exists — just not via RG
This is the exact solution the agents found when they
broke the RG fixed point assumption.
- BraidDiatCodec.lean: BraidDiatFrame now handles encode/decode of full
SpherionState × BraidReceipt with 256-bit header and variable mountain list
- braid_diat_codec.py: Python extraction updated to match, benchmark artifact
at shared-data/artifacts/braid_diat_codec_benchmark.json (714B avg vs
messagepack 1748B avg)
