# SILVERSIGHT WORK LOG
## Every Step Verifiable with a Calculator. No Code Until Math Passes.
# SilverSight Work Log
**Rule:** Each step produces a number (or set of numbers). You verify the number
before proceeding. If the number is wrong, STOP. Do not continue. The error must
be found.
## 2026-06-26
### Sidon-Orthogonality Bypass
**Files:** `formal/SilverSight/PIST/UnifiedCovariant.lean`,
`docs/reviews/SIDON_ORTHOGONALITY_BYPASS_FORMULA.md`,
`docs/reviews/CONJECTURE_UPGRADE_ROADMAP.md`, `BREAKGLASS_LOG.md`, `AGENTS.md`
Closed the operator-norm gap (`TODO(lean-port: operator_norm_bound)`) by
replacing spectral-radius analysis with a computable L∞ row-sum bound
over `Fin 8`.
**Key results:**
- `crossingMatrix: Matrix (Fin 8) (Fin 8) ` with explicit Sidon entries
- `maxRowSum` — L∞ row-sum norm, verified by `dec_trivial`
- `crossing_matrix_norm_bound`: `maxRowSum ≤ 1775/1792`
- `braid_operator_contractive`: `‖C·s‖_∞ ≤ r·‖s‖_∞`
- Removed deprecated `EigensolidConvergenceHypothesis`
- `lake build SilverSight`: 3307 jobs, 0 errors
### Branch cleanup
- Deleted stale remote branch `v4-verified-engine`
- SilverSight: `main` only (local + remote)
- BioSight confirmed: `master` only (local + remote)

## PHASE 0: FOUNDATION (COMPLETE — verified)
## 2026-06-26 (earlier)
These are established mathematical results. No code. No proof required. They are
given.
### Cold Reviewer Protocol + Unified Covariant Field Theory
**Files:** `formal/SilverSight/PIST/UnifiedCovariant.lean`,
`docs/reviews/COLD_REVIEWER_FORMULA.md`,
`docs/reviews/BREAKGLASS_FUSION_REVIEW_SPEC.md`
| Step | What | Formula | Status |
|------|------|---------|--------|
| 0.1 | **Fisher metric** | g_p(u,v) = Σᵢ uᵢvᵢ/pᵢ | Given (Chentsov 1972, Amari 1985) |
| 0.2 | **√p embedding** | φ(p) = (√p₁,...,√p₈) ∈ S⁷ | Given (pullback: g_p = 4·φ*g_{S⁷}) |
| 0.3 | **Fisher distance** | d_F(p,q) = 2·arccos(Σᵢ√(pᵢqᵢ)) | Given (Bhattacharyya arc) |
| 0.4 | **Φ-corkscrew** | f(n) = (√n·cos(nψ), √n·sin(nψ)), ψ = 2π/φ² | Given (irrational → injective) |
| 0.5 | **Golden ratio** | φ = (1+√5)/2 = 1.6180339887... | Given |
Initial rewrite with Cold Reviewer Protocol header:
- Layer 1: 4 discrete invariants, 0 sorries (φ²-φ-1=0, σ-τ=17/1792, F₇=13∧F₈=21, Sidon uniqueness)
- Layer 2: J²=J+I, Sidon crossing matrix
- Layer 2b: `eigensolid_convergence` upgraded from hypothesis to theorem (real analysis, squeeze theorem)
- Layer 3: 7 sorries (geometric conjectures deferred pending Mathlib)
**Verify 0.5:** Type `(1+sqrt(5))/2` into calculator → 1.6180339887...
Three red flags eliminated with `⚠ RED FLAG AVOIDED` annotations:
- J²=-I → J²=J+I
- Δ₇ Kähler → ℂℙ⁷
- dim(TL₇)=13 → dim(TL₇)=429

| **6.6** | **"p/q=r"** | **Same pipeline** | **Different n (different operation)** | **✓ PASS / ✗ STOP** |

## PHASE 7: ONLY NOW CODE (all math verified)
**Prerequisite:** Phases 1-6 all PASS. Every number verified by calculator.

| 7.2 | Implement parse-tree (2.5) | Input: "a+b=c" | Output matches hand-count |
| 7.3 | Implement chaos game (3.1-3.5) | Run 100 iterations | Final distance < 10^{-6} |
| 7.4 | Implement eigensolid (4.1-4.4) | Input: any p ∈ Δ₇ | C(C(p)) == C(p) |
| 7.5 | Implement Φ-corkscrew (5.1-5.5) | Input: q ∈ Δ₃ | Output: integer n |
| 7.6 | Full pipeline (6.1-6.6) | "a+b=c", "p/q=r" | Different spiral indices |
| **7.7** | **Cross-check all outputs** | **Same inputs as worksheets** | **Numbers match EXACTLY** | **✓ ALL PASS / ✗ STOP** |
---
## THE STOP CONDITIONS
**STOP and do not proceed if:**
1. Any worksheet number does not match calculator output
2. d_F(C(p), C(q)) ≥ d_F(p,q) in G1.5 or G3.6
3. τ("a+b=c") = τ("p/q=r") in G2.7
4. f(n) = f(m) for n ≠ m in 5.6
5. "a+b=c" and "p/q=r" produce same spiral index in 6.6
6. Code output does not match hand-computed worksheet number in 7.7
**There are no other reasons to stop.** Every error is found by comparing a
number on the screen to a number from a calculator.
