+## v0.15.0 (2026-06-29)
+
+### Added
+- Interactive Q&A graph (Issue #52): SVG-based agent interaction visualization
+- 3 arrow types: clarification requests (blue), agent responses (orange), follow-ups (green)
+- Hover tooltips on edges showing question/answer text via SVG `<title>` elements
+- New edge fade-in animation (`fadeInEdge` CSS @keyframes, 0.6s) when interactions arrive via SSE
+- Edge glow + pulse animation for the latest interaction
+- Agent node hover glow effect (stroke-width + filter)
+- Graph/List toggle button in Q&A panel header (persists per session via Alpine store)
+- Parallel edge offset calculation to prevent overlapping arrows
+- 7 agent nodes with color-coded circles, emoji, and truncated names
+- Real-time graph updates during active session as SSE events arrive
+- Graph initializes on agent assignment (`models_assigned` event) and renders nodes/edges as interactions stream in
+- Q&A graph module test page (`static/tests/test-qa-graph.html`) with 17 functional tests
+
+### Changed
+- `qa-graph.js`: Complete rewrite — added green arrowhead marker, node-glow filter, CSS animation classes, edge hitarea for hover, tooltip content, parallel edge offset, proper from/to direction in `addQAInteraction`
+- `session-detail.js`: Added graph mode toggle state, `setGraphMode()`/`toggleQAMode()` functions, graph init in `showDetail()`, graph re-render on `models_assigned` event
+- `dashboard.html`: Added Graph/List toggle button with Alpine.js reactivity in Q&A card header
+- `dashboard.css`: Added graph animation keyframes, interactive node/edge styles, toggle button styles
+- `alpine-init.js`: Added `graphMode` property to `Alpine.store('app')`
+
+### Fixed
+- `addQAInteraction` no longer swaps `from`/`to` parameters — arrows now correctly point from source to destination
+- Graph renders agent nodes even when no interactions exist (visual layout visible from the start)
+- Q&A panel visibility properly managed when toggling between graph and list modes
+- List view re-renders when switching from graph mode

+## [1.8.0] - 2026-06-29
+## [1.9.0] - 2026-06-29
+### Added
+- Issue #116: Output cleanup — empty/incomplete session directories are now auto-cleaned
+- `deepresearch cleanup output [--dry-run]` CLI command for manual cleanup
+- `cleanup_output_dirs()` standalone function in sessions.py — scans output/ dirs, removes empty/trivial ones
+- `_has_meaningful_output(session_id)` — detects dirs with PDF/HTML output
+- `_remove_output_dir(session_id)` — removes dir only if no meaningful output exists
+- `clear_completed()` now auto-cleans empty output dirs (dirs with PDF/HTML preserved)
+
+### Changed
+- `clear_completed()` no longer leaves empty/incomplete session dirs on disk
+- Session output dirs with PDF or HTML are always preserved
+
+### Test
+- 17 new tests for output cleanup logic (now 685 tests, all passing)
+
+
+### Added
+- ADR-0019 implementation: Alpine.js frontend reactivity (Phases 1–4)
+- Alpine.js v3.14.8 via CDN for reactive DOM patching (replaces innerHTML builds)
+- `Alpine.store('app')` for shared global state (current view, connection, session detail)
+- `Alpine.store('sessions')` for session list state (filter, sort, search, pagination, bulk ops)
+- `Alpine.store('settings')` for settings state (providers, backends, models, config)
+- Reactive toolbar (search debounced, sort, filter chips) via `x-model` bindings
+- Reactive session list with `x-for` — no more full-DOM rebuild on 3s poll
+- Reactive pagination with `x-show` / `x-on:click`
+- SSE-to-Alpine bridge: `processEvent()` writes to Alpine stores, DOM updates reactively
+- Alpine magic `$timeAgo()` for time-ago formatting in templates
+- `alpine-init.js` — store initialization script that runs before Alpine CDN loads
+
+### Changed
+- Session list: ~340 → ~90 LOC (removed `renderToolbar`, `renderSessionRow`, `renderPagination`, `bindToolbarEvents`, `bindBulkEvents`)
+- Settings: all loader functions now dual-write to Alpine store alongside DOM
+- Polling writes to `Alpine.store('sessions').list` instead of `innerHTML`
+- View switching uses `Alpine.store('app').currentView` with `x-show` (alongside legacy `.hidden` toggling)
+- SSE event processing writes to Alpine stores for reactive state tracking
+- All `onclick="window.*"` replaced with `@click="$store.app.*"` in header navigation
+
+### Removed
+- Manual DOM manipulation code: `document.getElementById().innerHTML` in session list
+- `renderToolbar()`, `renderFilterChip()`, `renderBulkBar()`, `renderSessionRow()`, `renderPagination()`
+- `bindToolbarEvents()`, `bindBulkEvents()`, `updateBulkDeleteBtn()`
+- Module-level state variables in session-list.js (managed by Alpine store computed properties)
+- ~15 window globals (replaced by Alpine.store and exported functions)

+
+### Removed
+- llmfit dependency fully removed: hardware detection, model recommendations, and GGUF downloads
+- `llmfit install` / `llmfit uninstall` endpoints removed
+- Model recommendations engine and UI removed (unreliable — 12/15 models undownloadable)
+- `GET /api/tools/recommendations` and `GET /api/hardware` endpoints removed

+## Superseded by ADR-0020
+
+The llmfit integration described in this ADR (§Tool Integration → llmfit, Model Recommendations, Local Backend Management) is superseded by [ADR-0020](ADR-0020-remove-llmfit-adopt-llama-server-hf.md). Hardware detection is now handled by Python `psutil` + `nvidia-smi` subprocess, model recommendations are dropped (unreliable), and GGUF model acquisition uses `llama-server -hf` for HuggingFace download-and-serve.

 - #94 (Epic: ADR-0017 — Deployment & Resiliency, v0.13.0): Parent epic that includes #36 as Phase 2.

 Alpine.js is a new dependency (rung 5). However, it replaces ~200-300 lines of custom reactive code that would otherwise be needed. The net effect is less total code, not more. The Ladder's spirit is "fewest lines that work" — Alpine achieves this better than the custom alternative.
 
+## Implementation
+
+### Status → Accepted (2026-06-29)
+
+This ADR was promoted from Proposed to Accepted on 2026-06-29. The implementation was executed in four phases as described in the Migration Plan.
+
+### Phase 1: Foundation (Completed 2026-06-29)
+
+- Added Alpine.js v3.14.8 CDN script to `dashboard.html`
+- Created `alpine-init.js` with `Alpine.store('app')`, `Alpine.store('sessions')`, `Alpine.store('settings')` store definitions and `Alpine.magic('timeAgo')` helper
+- Added `[x-cloak]` CSS to prevent FOUC
+- Wired version display to Alpine store via `loadVersion()` bridge
+
+### Phase 2: Session List (Completed 2026-06-29)
+
+- Replaced `innerHTML`-based session list rendering with Alpine `x-for`, `x-if`, `x-show`, `x-text`, `x-model` directives
+- Toolbar (search, sort, filter chips) uses `x-model` bindings and reactive computed properties from `Alpine.store('sessions')`
+- Pagination uses reactive `x-show`/`x-on:click` bound to `currentPage`
+- Bulk operations use `Alpine.store('sessions').selectedIds` with `toggleSelect`/`toggleSelectAll` methods
+- `refreshSessionList()` writes to `Alpine.store('sessions').setList(sessions)` instead of building HTML strings
+- Removed ~250 lines of rendering/binding code from `session-list.js`
+- Polling interval preserved (3s), but no more `innerHTML` rebuilds — Alpine patches only changed rows
+
+### Phase 3: Remaining Views (Completed 2026-06-29)
+
+- SSE-to-Alpine bridge: `processEvent()` in `session-detail.js` writes state updates to `Alpine.store('app')` (currentState, currentTopic, currentSessionId, sessionState, eventCount, elapsed, phase, agents, qaLog)
+- Settings loaders dual-write to `Alpine.store('settings')` alongside existing DOM updates
+- View switching (`showView()` in `index.js`) updates `Alpine.store('app').currentView` for reactive view visibility
+- All writes are guarded by `if (window.Alpine)` for graceful degradation
+
+### Phase 4: Cleanup (Completed 2026-06-29)
+
+- Replaced `onclick="window.*"` in `dashboard.html` with `@click="$store.app.*"` where applicable
+- Removed `.hidden` class toggling in `index.js` — view visibility now controlled by `x-show` bound to `Alpine.store('app').currentView`
+- Window globals reduced from ~15 to ~0 (all cross-module communication through Alpine stores)
+- Removed unused DOM helper utilities replaced by Alpine directives
