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).

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.

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

Adds three definitions/lemmas at module scope in FixedPoint.lean,
before the Q16_16 namespace:
q16Clamp (i : Int) : Int
— pure-Int clamp to [q16MinRaw, q16MaxRaw]; no subtype, no proof field.
q16Clamp_monotone (a b : Int) (h : a ≤ b) : q16Clamp a ≤ q16Clamp b
— proved once by the by_cases / simp / dsimp / omega pattern;
all future monotonicity proofs inherit from here.
q16Clamp_id_of_inRange (i : Int) (hlo hhi) : q16Clamp i = i
— idempotence on in-range values; one simp call.
Inside Q16_16 namespace, replaces the 38-line ofRawInt_monotone case-split
with two short lemmas:
ofRawInt_toInt_eq_clamp (i : Int) : (ofRawInt i).toInt = q16Clamp i
— bridge between the subtype constructor and the pure-Int function;
proved by split_ifs <;> rfl.
ofRawInt_monotone (a b : Int) (h : a ≤ b) :
(ofRawInt a).toInt ≤ (ofRawInt b).toInt
— now a two-line proof: simp [ofRawInt_toInt_eq_clamp] + q16Clamp_monotone.
add_nonneg_monotone is unchanged; it still delegates to ofRawInt_monotone.

FixedPoint.lean — two new theorems:
ofRawInt_monotone (a b : Int) (h : a ≤ b) :
(ofRawInt a).toInt ≤ (ofRawInt b).toInt
— proved by explicit by_cases on all four guard combinations
(a/b each: above max, below min, in range), closing each branch
with simp + dsimp [q16MinRaw/q16MaxRaw] + omega/exact.
add_nonneg_monotone (a b : Q16_16) (hb : 0 ≤ b.toInt) :
a.toInt ≤ (add a b).toInt
— follows from ofRawInt_monotone + ofRawInt_toInt (one rewrite).
Semantics.PIST.Motif §6.2 — upgraded from concrete witness to general theorem:
motifScore_match_ge_base (x : MotifInputs) :
(motifScore {x with familyMatch := true}).toInt ≥
(motifScore {x with familyMatch := false}).toInt
— now proved for all MotifInputs using add_nonneg_monotone,
replacing the earlier TODO(lean-port) placeholder.
