Systematic native_decide → dec_trivial/rfl migration across all Lean modules to comply with AGENTS.md rule 5 (no native_decide unless only option): - CoreFormalism: BraidEigensolid, BraidField, ChentsovFinite, HachimojiBase, HachimojiBridging, HachimojiCodec, HachimojiLUT, HachimojiManifoldAxiom, Q16_16Numerics - BindingSite: BindingSiteCodec, BindingSiteEntropy, BindingSiteHachimoji - SilverSight: ProductSchema, ProductWireFormat, PolyFactorIdentity, Schema, WireFormat - PVGS_DQ_Bridge: all three files (native_decide->dec_trivial) - UniversalEncoding/ChiralitySpace Additional changes: - gemma4_mcp.py: upgraded to two-tier routing (local Gemma4 + FreeLLMAPI proxy) - ChentsovFinite: added traceability map and Chentsov (1972) citation - HachimojiBase: renamed Σ→Sig, Π→Pi to avoid non-ASCII issues - Import path fixes for Mathlib 4.30.0-rc2 compatibility - Doc updates: PURE_FORMULAS, SOS_CERTIFICATE, fundamental math derivations - Build log: 2026-06-26 session findings - BRKGLASS_NR_BRACKET_PROPOSAL: updated to REAL-DATA VALIDATED status - New docs: FOUNDATIONAL_GUIDANCE, PURE_EQUATION_MAP, CHENTSOV_FINITE_MATH, BREAKGLASS_FUSION_REVIEW_SPEC, COLD_REVIEWER_FORMULA - New python: phi pipeline (equation_dna_encoder, ast_parse, charclass, consistency, embed, output), nr_bracket_validation with receipt Build: lake build SilverSightRRC — passes on all committed modules. Excluded: HachimojiN8Bridge, HachimojiCharClass (missing CoreFormalism.HachimojiManifoldAxiom olean — WIP)
