Avenue 7 from PR #125 research memo. Codifies dopamine source as a nucleus with its own firing log + state, rather than a derived quantity in bg_td_events + bg_modulators. - Migration 075: vta_state (single row, tonic_da + burst_budget + pathology_flag), vta_firings (timestamped burst log), vta_pathway_links (6 seeded: mesolimbic→NAc/amygdala, mesocortical→PFC/ACC, nigrostriatal→BG, broadcast→bg_modulators). - 5 MCP tools: status, fire, set_tonic, pathways, history. - 8 tests. - Pairs with Habenula PR #124 — Phase 3 wires habenula.suggested_da_damp into vta_state.tonic_da.
