is uncovered. Proves the Lonely Runner Conjecture for the infinite
family of consecutive integer speeds. Subsumes k=2 and k=3 lemmas.

vectorFieldℝ is affine linear (ContDiff ℝ 1 via fun_prop), satisfying
Picard-Lindelöf. Zero sorries remaining in file.

- 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).

The existence half of Picard-Lindelöf for finite-dimensional systems (Fin n → ℝ)
is now fully proven. The proof factors into:
1. exists_forward_solution — generic lemma building a forward solution on [0,∞)
for any Lipschitz vector field via Nat.rec over τ-intervals with
HasDerivWithinAt.union at boundaries and Nat.find indexing.
2. Time reversal via f_neg (x ↦ -f x) applied to exists_forward_solution gives
the backward solution.
3. γ_full splices both halves with case split at t=0.
4. The splice point t=0 is resolved via
hasDerivAt_iff_tendsto_slope_left_right, with the left slope obtained by
composing the negative-forward slope with y ↦ -y and an algebraic identity
γ_full(y) = γ_neg_fwd(-y) on y ≤ 0.
Previously 1 sorry (the existence existence) remained; it is now closed.
The uniqueness half was already proven via ODE_solution_unique_univ.

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/).

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

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:

AdjugateMatrix.lean:

- 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
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.

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
