# SilverSight Work Log
## 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)

### 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`
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)
Three red flags eliminated with `⚠ RED FLAG AVOIDED` annotations:
- J²=-I → J²=J+I
- Δ₇ Kähler → ℂℙ⁷
- dim(TL₇)=13 → dim(TL₇)=429
### Cold Reviewer Protocol
**Files:** `docs/reviews/COLD_REVIEWER_PROTOCOL.md`
Standalone protocol document with explicit two-gate structure (Arithmetic + Structural), step-by-step calculator verification for each invariant, extension rules, and binary PASS/FAIL decision procedure.
### Cartan Connection Formula
**Files:** `docs/reviews/CARTAN_CONNECTION_FORMULA.md`
Standalone formula for the hardest Layer 3 conjecture: a Cartan connection of type (SO^0(1,6) x R^7, SO^0(1,6)) on J^1(Delta_7). Covers the Klein geometry model, Sidon pinning of curvature, algebraic implementation path via LieAlgebra + BilinForm.
### Branch cleanup
- Deleted stale remote `origin/v4-verified-engine`
- SilverSight: `main` only; BioSight: `master` only
