SUNSET NOTICE + STRATEGIC SHIFT (12 Sep 2026, Mike, Perplexity session 10:27): SECOND BRAIN WILL RETIRE. MINI-SPHERE (Mini SphereDO) is the long-term architecture — portable, pluggable, cartridge. This evolves the earlier 'always plural, complementary systems' note: SB stays READ-AVAILABLE during transition but receives no new canonical writes after migration. First job for Mini SphereDO: gap-spec + hardening (typed storage tiers: documents, append-only logs, git-backed artifacts; dual-mode surfaces; cartridge packaging; SB migration mapping with stable provenance links). Sphere = typed storage provider (notes/documents/logs/artifacts via stacking + fan-out); boards = CRUD surface inside workspheres, MCP tools = ambient surface outside.
