 # daily-board
 
-Today's salon board: appointments, tasks, and priorities.
+Today's salon board: appointments, gaps, and confirmation flags.
 
 ## Description
 
-Pulls together the day's schedule, pending tasks, and key metrics into a single board view for the salon owner.
+Builds a structured daily board from scheduling data showing:
+- **Appointments** — time, client, service, staff, status
+- **Gaps** — unbooked slots ≥30 minutes between appointments
+- **Confirmation flags** — appointments that still need client confirmation
+- **Summary** — total booked time, gap time, appointment count
+
+All data is labeled with its source. When using fixtures, output is clearly
+marked `📋 FIXTURE DATA` so the owner never sees silent fake live data.
+
+## Data sources
+
+| Source | Status | Label in output |
+|--------|--------|-----------------|
+| Fixtures (JSON) | ✅ Implemented | `📋 FIXTURE DATA` |
+| Vagaro | Not yet | `📅 LIVE DATA` (future) |
+| Square | Not yet | `📅 LIVE DATA` (future) |
 
 ## Constraints
 
-- Deterministic facts from tools; inference for ranking and wording only.
+- Deterministic facts from fixtures; no model inference for board data.
 - No silent send or publish.
+- Cancelled appointments are excluded from the board view.
+- Gaps under 30 minutes are not shown (too short for a meaningful slot).
+- Output always labels fixture/offline — never silent fake live data.
+
+## Usage
+
+### CLI
+
+```bash
+# Build board from fixtures (default demo data)
+python skills/daily-board/scripts/build_board.py
+
+# Build board for a specific fixture file
+python skills/daily-board/scripts/build_board.py \
+  --fixtures data/fixtures/scheduling/claire_bennett_2026-07-28.json
+
+# Output as JSON
+python skills/daily-board/scripts/build_board.py --format json
+
+# Specify date and salon name explicitly
+python skills/daily-board/scripts/build_board.py \
+  --date 2026-07-28 --salon "Lumina Hair Studio & Spa"
+```
+
+### Programmatic
+
+```python
+from lumina_skills.providers.scheduling.fixture_provider import load_fixtures
+from lumina_skills.board_builder import build_board, format_board_text
+
+appointments = load_fixtures("data/fixtures/scheduling/claire_bennett_2026-07-28.json")
+board = build_board(appointments, date="2026-07-28", salon_name="Lumina Hair Studio & Spa")
+print(format_board_text(board))
+```
+
+## Output format
+
+### Text (default)
+
+Structured text with sections for appointments, gaps, confirmation flags, and summary.
+
+### JSON
+
+```json
+{
+  "date": "2026-07-28",
+  "salon_name": "Lumina Hair Studio & Spa",
+  "source": "fixtures",
+  "is_offline": true,
+  "appointments": [...],
+  "gaps": [...],
+  "needs_confirmation": [...],
+  "total_booked_minutes": 420,
+  "total_gap_minutes": 120
+}
+```
