+
+### `mma_agent_focus_ux` (not yet created)
+**Priority:** High
+**Depends on:** nothing
+**Origin:** User feedback 2026-03-02 — token viz is agent-agnostic; MMA observability panels (comms, tool calls, discussion history, token budget) show global/session-scoped data with no way to isolate a specific tier or agent.
+
+**The Gap (audit-confirmed):**
+- `_comms_log` entries (gui_2.py:861–895) have no tier/agent tag — only `direction`, `type`, `payload`
+- `_tool_log` entries (gui_2.py:897–900) are `(script, result, ts)` — no tier tag
+- `mma_streams` dict uses `stream_id` (`"Tier 1"` etc.) — the **only** existing per-agent key
+- `_on_comms_entry` never attaches caller tier/agent context
+- Token stats are global (single `ai_client` provider, no per-tier history separation)
+
+**Intent:**
+1. Add a `source_tier` / `agent_id` field to comms log entries and tool log tuples at the point of emission
+2. Add a "Focus Agent" selector widget to the MMA Dashboard (None = global; Tier 1–4 = filtered)
+3. Filter `_render_comms_history_panel`, `_render_tool_calls_panel`, and `_render_discussion_panel` by the selected agent when focus is active
+4. Token budget panel: when a tier is focused, show token stats for that tier's model/history (requires per-tier history tracking in ai_client or conductor engine)
+5. Discussion history entries emitted by MMA workers (via `history_add` comms kind) already carry a `role` — use that to group by tier
+
+**Scope note:** Item 4 (per-tier token stats) is the most architectural — may warrant a sub-track or phased deferral.
+
+**To initialize:** Run `/conductor-new-track mma_agent_focus_ux` at start of next session after reading this file.
