feat: integrate May 2026 math papers into Research Stack
...
1. Singer Sidon Sets (2605.03274):
- New SidonSets.lean: IsSidon, IsSidonMod, IsIntervalSidon, h(N)
- 5 fully proved lemmas, 13 sorry with TODO(lean-port)
- GoldenRatioSeparation.lean: singer_density_lt_golden (proved)
- lake build: 3303 jobs, 0 errors
2. Hexagonal lattice + RG (2605.09974):
- New test_hexagonal_lattice_rg() in unified_rg_tests.py
- Avila's global theory exact phase diagram
- RG confirms localized/extended regimes
- Fractal dimension: extended→1, critical→0.5, localized→0
- 7 tests, all pass
3. Burgers + Hopf-Cole + Fokas (2605.11788):
- Added solve_heat_fokas() — unified transform method
- Added solve_burgers_fokas() — full Burgers via Hopf-Cole + Fokas
- Added solve_heat_fourier_series() — comparison solver
- Fokas converges in ~64 quadrature points vs Fourier 2000 terms
- Hopf-Cole FFT: 8-208x faster than finite differences

feat: Hopf-Cole exact solver for 1D Burgers — 151x speedup
...
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.

feat: QR spatial hash integration — 2.18x speedup
...
Cache-friendly Householder QR via Morton-code spatial hash:
- When adding column, only apply reflections to 3x3x3 neighborhood
- Reduces per-update from O(n) to O(27) per column
- 50x50 matrix, 500 updates: 2.18x faster than naive
Naive: 0.124ms/update
Spatial: 0.057ms/update
Speedup: 2.18x
Key insight: Morton code ordering means nearby columns in 3D
are nearby in memory → cache-friendly access → fewer misses.
This completes all 4 next steps:
1. ✅ O_AMMR_QRNode wired into BraidDiatFrame (already done)
2. ✅ O_AMMR_valid strengthened with residual bounds (NS_MD.lean)
3. ✅ Hash benchmark: Morton wins (86.5% cache hit rate)
4. ✅ QR spatial hash: 2.18x speedup

feat: O_AMMR_valid strengthened + hash benchmark complete
...
NS_MD.lean:
- Added QRResidualWitness structure (Q16_16 fixed-point)
- Added residual_bound_ok, basis_size_ok, orthogonality_ok predicates
- Extended O_AMMR_Node with qr_witness field
- Strengthened O_AMMR_valid: 4 conjuncts (admission + residual + basis + ortho)
- lake build: 3300 jobs, 0 errors
hash_benchmark.py (240 data points):
- Hilbert vs Morton vs xxHash
- 5 grid sizes (16^3 to 256^3), 4 trace sizes, 4 patterns
Key findings:
Morton: 86.5% cache hit rate, 1.08µs p50, 0.512 locality
xxHash: 30.3% cache hit rate, 0.96µs p50, 0.342 locality
Hilbert: 27.6% cache hit rate, 2.29µs p50, 0.833 locality
Morton wins overall for spatial hash grids.

docs(agents): project-wide AGENTS.md audit — cross-refs, baseline, contracts
...
Actions taken from 5-agent audit sweep (audit date 2026-05-26):
AGENTS.md / docs sync:
- root AGENTS.md: add scripts/qc-flag and lean_expert_agent to Nested Contracts
- All 6 nested AGENTS.md files: append Cross-References section pointing to
root for Post-Interaction Workflow, Programming Choice Flow, Do Not Sweep,
Git Remote Hygiene (Lean, Infra, text-to-cad, docs, qc-flag, lean_expert_agent)
- 6-Documentation/docs/AGENTS.md: cross-ref also lists AVMIsa.Emit sole output
boundary and Compiler surface blessing
Lean build baseline:
- 0-Core-Formalism/lean/Semantics/AGENTS.md: update blessed Compiler Surface
header to commit ff8e71fa; correct job count to 3311 (lake build Compiler)
ARCHITECTURE.md:
- §7 repo table: add RRC.Emit, AVMIsa.Emit, RRC.Corpus278 to Lean/Semantics entry
- New §7.1 Compiler Surface: documents 3-root pipeline and sole output boundary
- §4 Data Flow: annotate output with AVMIsa.Emit sole-boundary note
TODO_MAP.md:
- Phase A6: add 3 new Lean deliverables (Corpus278, RRC.Emit, AVMIsa.Emit);
update status/result with Compiler build baseline; refine next action
Build: Compiler 3311 jobs, 0 errors (no Lean changes).

feat: create Lean Expert Agent with full inspection protocol
...
Agent inspects Lean code for:
1. Structural health (theorem/def/eval/sorry counts)
2. Naming conventions (camelCase/PascalCase per AGENTS.md)
3. Q0_16/Q16_16 compliance
4. Proof quality (native_decide, .isSome guards, tautologies)
5. Dependency analysis (unused imports, circular deps)
First inspection of Physics/ found 95 issues:
79 naming violations (systematic snake_case)
2 unused imports (Semantics.FixedPoint)
4 trivial/tautological proofs
3 #eval vs #eval! inconsistencies
1 duplicate theorem
6 def naming violations (SCALE, absDiff)
