stats

## Runtime Configuration (Step 0 — before any processing)

Read these files to configure domain-specific behavior:

1. **`ops/derivation-manifest.md`** — vocabulary mapping
   - Use `vocabulary.notes` for the notes folder name
   - Use `vocabulary.note` / `vocabulary.note_plural` for note type references
   - Use `vocabulary.topic_map` / `vocabulary.topic_map_plural` for MOC references
   - Use `vocabulary.inbox` for the inbox folder name
   - Use `vocabulary.notes_collection` for semantic search collection name

2. **`ops/config.yaml`** — processing depth, automation settings

If no derivation file exists, use universal terms (notes, MOCs, etc.).

## EXECUTE NOW

**Target: $ARGUMENTS**

Parse immediately:
- If target contains `--share`: output compact shareable format after full stats
- If target is empty: output full stats display
- If target names a specific category (e.g., "health", "growth", "pipeline"): show only that category

**START NOW.** Collect metrics and present them.

---

## Philosophy

**Make the invisible visible.**

The knowledge graph grows silently. Without metrics, the user cannot tell whether their system is healthy, growing, stagnating, or fragmenting. /stats provides a snapshot that makes growth tangible — numbers that show progress, health indicators that catch problems, and trends that reveal trajectory.

The output should make the user feel informed, not overwhelmed. Metrics are evidence, not judgment. "12 orphans" is a fact. What to DO about it belongs to /graph or /{vocabulary.cmd_reflect}.

---

## Step 1: Collect Metrics

Gather all metrics. Run these checks in parallel where possible to minimize latency.

### 1a. Knowledge Graph Metrics

```bash
NOTES_DIR="{vocabulary.notes}"

# Note count (excluding MOCs)
TOTAL_FILES=$(ls -1 "$NOTES_DIR"/*.md 2>/dev/null | wc -l | tr -d ' ')
MOC_COUNT=$(grep -rl '^type: moc' "$NOTES_DIR"/*.md 2>/dev/null | wc -l | tr -d ' ')
NOTE_COUNT=$((TOTAL_FILES - MOC_COUNT))

# Connection count (all wiki links across notes/)
LINK_COUNT=$(grep -ohP '\[\[[^\]]+\]\]' "$NOTES_DIR"/*.md 2>/dev/null | wc -l | tr -d ' ')

# Average connections per note
if [[ "$NOTE_COUNT" -gt 0 ]]; then
  AVG_LINKS=$(echo "scale=1; $LINK_COUNT / $NOTE_COUNT" | bc)
else
  AVG_LINKS="0"
fi

# Topic count (unique values in topics: fields)
TOPIC_COUNT=$(grep -ohP '^\s*-\s*"\[\[([^\]]+)\]\]"' "$NOTES_DIR"/*.md 2>/dev/null | sort -u | wc -l | tr -d ' ')

# Link density
if [[ "$NOTE_COUNT" -gt 1 ]]; then
  POSSIBLE=$((NOTE_COUNT * (NOTE_COUNT - 1)))
  DENSITY=$(echo "scale=4; $LINK_COUNT / $POSSIBLE" | bc)
else
  DENSITY="N/A"
fi
```

### 1b. Health Metrics

```bash
# Orphan count (notes with zero incoming links)
ORPHAN_COUNT=0
for f in "$NOTES_DIR"/*.md; do
  NAME=$(basename "$f" .md)
  grep -q '^type: moc' "$f" 2>/dev/null && continue
  INCOMING=$(grep -rl "\[\[$NAME\]\]" "$NOTES_DIR"/ 2>/dev/null | grep -v "$f" | wc -l | tr -d ' ')
  [[ "$INCOMING" -eq 0 ]] && ORPHAN_COUNT=$((ORPHAN_COUNT + 1))
done

# Dangling link count
DANGLING_COUNT=$(grep -ohP '\[\[([^\]]+)\]\]' "$NOTES_DIR"/*.md 2>/dev/null | sort -u | while read -r link; do
  NAME=$(echo "$link" | sed 's/\[\[//;s/\]\]//')
  [[ ! -f "$NOTES_DIR/$NAME.md" ]] && echo "$NAME"
done | wc -l | tr -d ' ')

# Schema compliance (% of notes with required fields: description, topics)
MISSING_DESC=$(grep -rL '^description:' "$NOTES_DIR"/*.md 2>/dev/null | wc -l | tr -d ' ')
MISSING_TOPICS=$(grep -rL '^topics:' "$NOTES_DIR"/*.md 2>/dev/null | wc -l | tr -d ' ')
SCHEMA_ISSUES=$((MISSING_DESC + MISSING_TOPICS))
if [[ "$TOTAL_FILES" -gt 0 ]]; then
  # Notes with BOTH required fields
  COMPLIANT=$((TOTAL_FILES - MISSING_DESC))
  COMPLIANCE=$(echo "scale=0; $COMPLIANT * 100 / $TOTAL_FILES" | bc)
else
  COMPLIANCE="N/A"
fi

# MOC coverage
COVERED=0
for f in "$NOTES_DIR"/*.md; do
  NAME=$(basename "$f" .md)
  grep -q '^type: moc' "$f" 2>/dev/null && continue
  if grep -rl '^type: moc' "$NOTES_DIR"/*.md 2>/dev/null | xargs grep -l "\[\[$NAME\]\]" >/dev/null 2>&1; then
    COVERED=$((COVERED + 1))
  fi
done
if [[ "$NOTE_COUNT" -gt 0 ]]; then
  COVERAGE=$(echo "scale=0; $COVERED * 100 / $NOTE_COUNT" | bc)
else
  COVERAGE="N/A"
fi
```

### 1c. Pipeline Metrics

```bash
# Inbox items
INBOX_COUNT=$(find {vocabulary.inbox}/ -name "*.md" 2>/dev/null | wc -l | tr -d ' ')

# Queue pending (check both YAML and JSON formats)
QUEUE_FILE=""
if [[ -f "ops/queue/queue.yaml" ]]; then
  QUEUE_FILE="ops/queue/queue.yaml"
  QUEUE_PENDING=$(grep -c 'status: pending' "$QUEUE_FILE" 2>/dev/null || echo 0)
  QUEUE_DONE=$(grep -c 'status: done' "$QUEUE_FILE" 2>/dev/null || echo 0)
elif [[ -f "ops/queue/queue.json" ]]; then
  QUEUE_FILE="ops/queue/queue.json"
  QUEUE_PENDING=$(grep -c '"status": "pending"' "$QUEUE_FILE" 2>/dev/null || echo 0)
  QUEUE_DONE=$(grep -c '"status": "done"' "$QUEUE_FILE" 2>/dev/null || echo 0)
else
  QUEUE_PENDING=0
  QUEUE_DONE=0
fi

# Processed ratio (notes vs inbox)
TOTAL_CONTENT=$((NOTE_COUNT + INBOX_COUNT))
if [[ "$TOTAL_CONTENT" -gt 0 ]]; then
  PROCESSED_PCT=$(echo "scale=0; $NOTE_COUNT * 100 / $TOTAL_CONTENT" | bc)
else
  PROCESSED_PCT="N/A"
fi
```

### 1d. Growth Metrics

```bash
# This week's growth (notes with created: date within last 7 days)
WEEK_AGO=$(date -v-7d +%Y-%m-%d 2>/dev/null || date -d '7 days ago' +%Y-%m-%d 2>/dev/null)
if [[ -n "$WEEK_AGO" ]]; then
  THIS_WEEK_NOTES=$(grep -rl "^created: " "$NOTES_DIR"/*.md 2>/dev/null | while read -r f; do
    CREATED=$(grep '^created:' "$f" | head -1 | awk '{print $2}')
    [[ "$CREATED" > "$WEEK_AGO" || "$CREATED" == "$WEEK_AGO" ]] && echo "$f"
  done | wc -l | tr -d ' ')
else
  THIS_WEEK_NOTES="?"
fi

# This week's connections (approximate — count links in recently created notes)
if [[ "$THIS_WEEK_NOTES" -gt 0 && -n "$WEEK_AGO" ]]; then
  THIS_WEEK_LINKS=$(grep -rl "^created: " "$NOTES_DIR"/*.md 2>/dev/null | while read -r f; do
    CREATED=$(grep '^created:' "$f" | head -1 | awk '{print $2}')
    [[ "$CREATED" > "$WEEK_AGO" || "$CREATED" == "$WEEK_AGO" ]
