+Implement Task 1.1 in @gui_2.py: replace the single "Strategy (Tier 1)" text box in _render_mma_dashboard with four collapsible tier stream sections.
+
+CURRENT CODE to replace (around lines 2728-2732 in gui_2.py):
+  imgui.separator()
+  imgui.separator()
+  imgui.text("Strategy (Tier 1)")
+  strategy_text = self.mma_streams.get("Tier 1", "")
+  imgui.input_text_multiline("##mma_strategy", strategy_text, imgui.ImVec2(-1, 150), imgui.InputTextFlags_.read_only)
+
+REPLACE with these four collapsible sections (insert after the token usage table separator, before "# 4. Task DAG Visualizer"):
+
+TIER DEFINITIONS:
+- Tier 1: label="Strategy", stream key="Tier 1"
+- Tier 2: label="Tech Lead", stream key="Tier 2 (Tech Lead)"
+- Tier 3: label="Workers", aggregates all mma_streams keys containing "Tier 3"
+- Tier 4: label="QA", stream key="Tier 4 (QA)"
+
+IMPLEMENTATION REQUIREMENTS:
+1. For Tier 1, 2, 4 (single stream):
+   if imgui.collapsing_header(f"Tier {N}: {label}"):
+    content = self.mma_streams.get(stream_key, "")
+    imgui.begin_child(f"##tier{N}_scroll", imgui.ImVec2(-1, 200), True)
+    imgui.text_wrapped(content)
+    imgui.end_child()
+
+2. For Tier 3 (aggregated):
+   if imgui.collapsing_header("Tier 3: Workers"):
+    tier3_keys = [k for k in self.mma_streams if "Tier 3" in k]
+    if not tier3_keys:
+     imgui.text_disabled("No worker output yet.")
+    else:
+     for key in tier3_keys:
+      ticket_id = key.split(": ", 1)[-1] if ": " in key else key
+      imgui.text(ticket_id)  # sub-header
+      imgui.begin_child(f"##tier3_{ticket_id}_scroll", imgui.ImVec2(-1, 150), True)
+      imgui.text_wrapped(self.mma_streams[key])
+      imgui.end_child()
+
+3. Auto-scroll: after imgui.begin_child, if the stream content changed since last frame, call imgui.set_scroll_here_y(1.0). Track last-seen content length in a dict self._tier_stream_last_len: dict[str, int] = {} (init in __init__ if not present). Only scroll if user was at bottom: check imgui.get_scroll_y() >= imgui.get_scroll_max_y() - 10 before deciding to scroll.
+
+4. REMOVE the old lines completely:
+   - imgui.separator() (the second duplicate separator before the old strategy box)
+   - imgui.text("Strategy (Tier 1)")
+   - strategy_text = self.mma_streams.get("Tier 1", "")
+   - imgui.input_text_multiline("##mma_strategy", ...)
+
+5. Also add `self._tier_stream_last_len: dict[str, int] = {}` to __init__ (around line 280, after self.mma_streams = {} line).
+
+TESTS that must pass after this change: @tests/test_mma_dashboard_streams.py
+
+Use exactly 1-space indentation for Python code.

+Create tests/test_mma_dashboard_streams.py — failing tests for Task 1.1 of comprehensive_gui_ux track.
+
+CONTEXT: _render_mma_dashboard in @gui_2.py currently has a single input_text_multiline for "Strategy (Tier 1)" (around line 2729). Task 1.1 replaces it with four collapsible sections using imgui.collapsing_header(), one per tier.
+
+TESTS TO WRITE (all should FAIL against current code — they test the NEW behavior):
+
+1. test_all_four_tier_headers_rendered:
+   - Create a mock App with mma_streams = {"Tier 1": "strat", "Tier 2 (Tech Lead)": "lead", "Tier 3 (Worker): T-001": "work", "Tier 4 (QA)": "qa"}
+   - Patch imgui.collapsing_header to record calls, patch imgui.begin_child to return True, patch imgui.end_child, patch imgui.input_text_multiline
+   - Call app._render_mma_dashboard()
+   - Assert collapsing_header was called with a string containing "Tier 1" AND "Tier 2" AND "Tier 3" AND "Tier 4"
+
+2. test_tier3_aggregates_multiple_worker_streams:
+   - mma_streams = {"Tier 3 (Worker): T-001": "output1", "Tier 3 (Worker): T-002": "output2"}
+   - Patch imgui.collapsing_header to return True, patch begin_child/end_child/text
+   - Call _render_mma_dashboard()
+   - Assert imgui.text was called with content containing "T-001" and "T-002" (sub-headers shown)
+
+3. test_old_single_strategy_box_removed:
+   - With any mma_streams, call _render_mma_dashboard()
+   - Assert imgui.input_text_multiline was NOT called with "##mma_strategy" as first arg
+   - (The old box should be gone, replaced by collapsing_header sections)
+
+IMPLEMENTATION DETAILS:
+- Import: import pytest, unittest.mock (patch, MagicMock, call)
+- The App class needs minimal init to avoid full GUI startup. Use a MagicMock for the app instance and manually attach method:
+  app = MagicMock(spec=App)
+  app.mma_streams = {...}
+  app.mma_tier_usage = {}
+  app.tracks = []
+  app.active_track = None
+  app.active_tickets = []
+  app.mma_status = "idle"
+  app.active_tier = None
+  app.mma_step_mode = False
+  app._pending_mma_spawn = None
+  app._pending_mma_approval = None
+  app._pending_ask_dialog = False
+  # Then call the unbound method:
+  from gui_2 import App
+  App._render_mma_dashboard(app)
+- Patch target: 'gui_2.imgui' module-level
+- Use 1-space indentation throughout.
+- All 3 tests should FAIL against the current code (which still has the old single text box).
