+# Specification: Smarter Aggregation with Sub-Agent Summarization
+
+## 1. Overview
+
+This track improves the context aggregation system to use sub-agent passes for intelligent summarization and hash-based caching to avoid redundant work.
+
+**Current Problem:**
+- Aggregation is a simple pass that either injects full file content or a basic skeleton
+- No intelligence applied to determine what level of detail is needed
+- Same files get re-summarized on every discussion start even if unchanged
+
+**Goal:**
+- Use a sub-agent during aggregation pass for high-tier agents to generate succinct summaries
+- Cache summaries based on file hash - only re-summarize if file changed
+- Smart outline generation for code files, summary for text files
+
+## 2. Current State Audit
+
+### Existing Aggregation Behavior
+- `aggregate.py` handles context aggregation
+- `file_cache.py` provides AST parsing and skeleton generation
+- Per-file flags: `Auto-Aggregate` (summarize), `Force Full` (inject raw)
+- No caching of summarization results
+
+### Provider API Considerations
+- Different providers have different prompt/caching mechanisms
+- Need to verify how each provider handles system context and caching
+- May need provider-specific aggregation strategies
+
+## 3. Functional Requirements
+
+### 3.1 Hash-Based Summary Cache
+- Generate SHA256 hash of file content
+- Store summaries in a cache (file-based or in project state)
+- Before summarizing, check if file hash matches cached summary
+- Cache invalidation when file content changes
+
+### 3.2 Sub-Agent Summarization Pass
+- During aggregation, optionally invoke sub-agent for summarization
+- Sub-agent generates concise summary of file purpose and key points
+- Different strategies for:
+  - Code files: AST-based outline + key function signatures
+  - Text files: Paragraph-level summary
+  - Config files: Key-value extraction
+
+### 3.3 Tiered Aggregation Strategy
+- Tier 3/4 workers: Get skeleton outlines (fast, cheap)
+- Tier 2 (Tech Lead): Get summaries with key details
+- Tier 1 (Orchestrator): May get full content or enhanced summaries
+- Configurable per-agent via Persona
+
+### 3.4 Cache Persistence
+- Summaries persist across sessions
+- Stored in project directory or centralized cache location
+- Manual cache clear option in UI
+
+## 4. Data Model
+
+### 4.1 Summary Cache Entry
+```python
+{
+    "file_path": str,
+    "file_hash": str,  # SHA256 of content
+    "summary": str,
+    "outline": str,  # For code files
+    "generated_at": str,  # ISO timestamp
+    "generator_tier": str,  # Which tier generated it
+}
+```
+
+### 4.2 Aggregation Config
+```toml
+[aggregation]
+default_mode = "summarize"  # "full", "summarize", "outline"
+cache_enabled = true
+cache_dir = ".slop_cache"
+```
+
+## 5. UI Changes
+
+- Add "Clear Summary Cache" button in Files & Media or Context Composition
+- Show cached status indicator on files (similar to AST cache indicator)
+- Configuration in AI Settings or Project Settings
+
+## 6. Acceptance Criteria
+
+- [ ] File hash computed before summarization
+- [ ] Summary cache persists across app restarts
+- [ ] Sub-agent generates better summaries than basic skeleton
+- [ ] Aggregation respects tier-level configuration
+- [ ] Cache can be manually cleared
+- [ ] Provider APIs handle aggregated context correctly
+
+## 7. Out of Scope
+- Changes to provider API internals
+- Vector store / embeddings for RAG (separate track)
+- Changes to Session Hub / Discussion Hub layout
+
+## 8. Dependencies
+- `aggregate.py` - main aggregation logic
+- `file_cache.py` - AST parsing and caching
+- `ai_client.py` - sub-agent invocation
+- `models.py` - may need new config structures

+# Specification: Discussion Hub Panel Reorganization
+
+## 1. Overview
+
+This track addresses the fragmented implementation of Session Context Snapshots and Discussion Takes & Timeline Branching tracks (2026-03-11). Those tracks were marked complete but the UI panel layout was not properly reorganized.
+
+**Goal:** Create a coherent Discussion Hub that absorbs Session Hub functionality, establishes Files & Media as project-level file inventory, and properly implements Context Composition and DAW-style Takes branching.
+
+## 2. Current State Audit (as of 2026-03-22)
+
+### Already Implemented (DO NOT re-implement)
+- `ui_summary_only` checkbox in Projects panel
+- Session Hub as separate window with tabs: Aggregate MD | System Prompt
+- Context Hub with tabs: Projects | Paths | Context Presets
+- Context Presets save/load mechanism in project TOML
+- `_render_synthesis_panel()` method (gui_2.py:2612-2643) - basic synthesis UI
+- Takes data structure in `project['discussion']['discussions']`
+- Per-file `Auto-Aggregate` and `Force Full` flags in Files & Media
+
+### Gaps to Fill (This Track's Scope)
+1. `ui_summary_only` is redundant with per-file flags - deprecate it
+2. Context Hub renamed to "Project Settings" (remove Context Presets tab)
+3. Session Hub merged into Discussion Hub as tabs
+4. Files & Media stays separate as project-level inventory
+5. Context Composition tab in Discussion Hub for per-discussion filter
+6. Context Presets accessible via Context Composition (save/load filters)
+7. DAW-style Takes timeline properly integrated into Discussion Hub
+8. Synthesis properly integrated with Take selection
+
+## 3. Panel Layout Target
+
+| Panel | Location | Purpose |
+|-------|----------|---------|
+| **AI Settings** | Separate dockable | Provider, model, system prompts, tool presets, bias profiles |
+| **Files & Media** | Separate dockable | Project-level file inventory (addressable files) |
+| **Project Settings** | Context Hub → rename | Git dir, paths, project list (NO context stuff) |
+| **Discussion Hub** | Main hub | All discussion-related UI (tabs below) |
+| **MMA Dashboard** | Separate dockable | Multi-agent orchestration |
+| **Operations Hub** | Separate dockable | Tool calls, comms history, external tools |
+| **Diagnostics** | Separate dockable | Telemetry, logs |
+
+**Discussion Hub Tabs:**
+1. **Discussion** - Main conversation view (current implementation)
+2. **Context Composition** - File/screenshot filter + presets (NEW)
+3. **Snapshot** - Aggregate MD + System Prompt preview (moved from Session Hub)
+4. **Takes** - DAW-style timeline branching + synthesis (integrated, not separate panel)
+
+## 4. Functional Requirements
+
+### 4.1 Deprecate ui_summary_only
+- Remove `ui_summary_only` checkbox from Projects panel
+- Per-file flags (`Auto-Aggregate`, `Force Full`) are the intended mechanism
+- Document migration path for users
+
+### 4.2 Rename Context Hub → Project Settings
+- Context Hub tab bar: Projects | Paths
+- Remove "Context Presets" tab
+- All context-related functionality moves to Discussion Hub → Context Composition
+
+### 4.3 Merge Session Hub into Discussion Hub
+- Session Hub window eliminated
+- Its content becomes tabs in Discussion Hub:
+  - **Snapshot tab**: Aggregate MD preview, System Prompt preview, "Copy" buttons
+  - These were previously in Session Hub
+
+### 4.4 Context Composition Tab (NEW)
+- Shows currently selected files/screenshots for THIS discussion
+- Per-file flags: Auto-Aggregate, Force Full
+- **"Save as Preset"** / **"Load Preset"** buttons
+- Dropdown to select from saved presets
+- Relationship to Files & Media:
+  - Files & Media = the inventory (project-level)
+  - Context Composition = selected filter for current discussion
+
+### 4.5 Takes Timeline (DAW-Style)
+- **New Take**: Start fresh discussion thread
+- **Branch Take**: Fork from any discussion entry
+- **Switch Take**: Make a take the active discussion
+- **Rename/Delete Take**
+- All takes share the same Files & Media (not duplicated)
+- Non-destructive branching
+- Visual timeline showing divergence points
+
+### 4.6 Synthesis Integration
+- User selects 2+ takes via checkboxes
+- Click "Synthesize" button
+- AI generates "resolved" response considering all selected approaches
+- Result appears as new take
+- Accessible from Discussion Hub → Takes tab
+
+## 5. Data Model Changes
+
+### 5.1 Discussion State Structure
+```python
+# Per discussion in project['discussion']['discussions']
+{
+    "name": str,
+    "history": [
+        {"role": "user"|"assistant", "content": str, "ts": str, "files_injected": [...]}
+    ],
+    "parent_entry": Optional[int],  # index of parent message if branched
+    "parent_take": Optional[str],   # name of parent take if branched
+}
+```
+
+### 5.2 Context Preset Format
+```toml
+[context_preset.my_filter]
+files = ["path/to/file_a.py"]
+auto_aggregate = true
+force_full = false
+screenshots = ["path/to/shot1.png"]
+```
+
+## 6. Non-Functional Requirements
+- All changes must not break existing tests
+- New tests required for new functionality
+- Follow 1-space indentation Python code style
+- No comments unless explicitly requested
+
+## 7. Acceptance Criteria
+
+- [ ] `ui_summary_only` removed from Projects panel
+- [ ] Context Hub renamed to Project Settings
+- [ ] Session Hub window eliminated
+- [ ] Discussion Hub has 4 tabs: Discussion, Context Composition, Snapshot, Takes
+- [ ] Context Composition allows save/load of filter presets
+- [ ] Takes can be branched from any entry
+- [ ] Takes timeline shows divergence visually
+- [ ] Synthesis works with 2+ selected takes
+- [ ] All existing tests still pass
+- [ ] New tests cover new functionality
+
+## 8. Out of Scope
+- Aggregation improvements (sub-agent summarization, hash-based caching) - separate future track
+- System prompt exposure (`_SYSTEM_PROMPT` in ai_client.py) - separate future track
+- Session sophistication (Session as container for multiple discussions) - deferred

+# Specification: System Context Exposure
+
+## 1. Overview
+
+This track exposes the hidden system prompt from `ai_client.py` to users for customization.
+
+**Current Problem:**
+- `_SYSTEM_PROMPT` in `ai_client.py` (lines ~118-143) is hardcoded
+- It contains foundational instructions: "You are a helpful coding assistant with access to a PowerShell tool..."
+- Users can only see/appending their custom portion via `_custom_system_prompt`
+- The base prompt that defines core agent capabilities is invisible
+
+**Goal:**
+- Make `_SYSTEM_PROMPT` visible and editable in the UI
+- Allow users to customize the foundational agent instructions
+- Maintain sensible defaults while enabling expert customization
+
+## 2. Current State Audit
+
+### Hidden System Prompt Location
+`src/ai_client.py`:
+```python
+_SYSTEM_PROMPT: str = (
+ "You are a helpful coding assistant with access to a PowerShell tool (run_powershell) and MCP tools (file access: read_file, list_directory, search_files, get_file_summary, web access: web_search, fetch_url). "
+ "When calling file/directory tools, always use the 'path' parameter for the target path. "
+ ...
+)
+```
+
+### Related State
+- `_custom_system_prompt` - user-defined append/injection
+- `_get_combined_system_prompt()` - merges both
+- `set_custom_system_prompt()` - setter for user portion
+
+### UI Current State
+- AI Settings → System Prompts shows global and project prompts
+- These are injected as `[USER SYSTEM PROMPT]` after `_SYSTEM_PROMPT`
+- But `_SYSTEM_PROMPT` itself is never shown
+
+## 3. Functional Requirements
+
+### 3.1 Base System Prompt Visibility
+- Add "Base System Prompt" section in AI Settings
+- Display current `_SYSTEM_PROMPT` content
+- Allow editing with syntax highlighting (it's markdown text)
+
+### 3.2 Default vs Custom Base
+- Maintain default base prompt as reference
+- User can reset to default if they mess it up
+- Show diff between default and custom
+
+### 3.3 Persistence
+- Custom base prompt stored in config or project TOML
+- Loaded on app start
+- Applied before `_custom_system_prompt` in `_get_combined_system_prompt()`
+
+### 3.4 Provider Considerations
+- Some providers handle system prompts differently
+- Verify behavior across Gemini, Anthropic, DeepSeek
+- May need provider-specific base prompts
+
+## 4. Data Model
+
+### 4.1 Config Storage
+```toml
+[ai_settings]
+base_system_prompt = """..."""
+use_default_base = true
+```
+
+### 4.2 Combined Prompt Order
+1. `_SYSTEM_PROMPT` (or custom base if enabled)
+2. `[USER SYSTEM PROMPT]` (from AI Settings global/project)
+3. Tooling strategy (from bias engine)
+
+## 5. UI Design
+
+**Location:** AI Settings panel → System Prompts section
+
+```
+┌─ System Prompts ──────────────────────────────┐
+│ ☑ Use Default Base System Prompt              │
+│                                              │
+│ Base System Prompt (collapsed by default):    │
+│ ┌──────────────────────────────────────────┐ │
+│ │ You are a helpful coding assistant...     │ │
+│ └──────────────────────────────────────────┘ │
+│                                              │
+│ [Show Editor] [Reset to Default]              │
+│                                              │
+│ Global System Prompt:                         │
+│ ┌──────────────────────────────────────────┐ │
+│ │ [current global prompt content]           │ │
+│ └──────────────────────────────────────────┘ │
+└──────────────────────────────────────────────┘
+```
+
+When "Show Editor" clicked:
+- Expand to full editor for base prompt
+- Syntax highlighting for markdown
+- Character count
+
+## 6. Acceptance Criteria
+
+- [ ] `_SYSTEM_PROMPT` visible in AI Settings
+- [ ] User can edit base system prompt
+- [ ] Changes persist across app restarts
+- [ ] "Reset to Default" restores original
+- [ ] Provider APIs receive modified prompt correctly
+- [ ] No regression in agent behavior with defaults
+
+## 7. Out of Scope
+- Changes to actual agent behavior logic
+- Changes to tool definitions or availability
+- Changes to aggregation or context handling
+
+## 8. Dependencies
+- `ai_client.py` - `_SYSTEM_PROMPT` and `_get_combined_system_prompt()`
+- `gui_2.py` - AI Settings panel rendering
+- `models.py` - Config structures
