/sync-paper - Cross-Document Synchronization Skill

Purpose

Ensure consistency between the authoritative paper (PAPER_2_DARK_EARTHQUAKES.md) and summary documents (ANOMALY_CATALOG.md, ANOMALY_TRACKING.md, GAPS_AND_PRIORITIES.md). Prevents documentation drift.

Usage

/sync-paper [--check | --update | --region REGION]

Examples:

/sync-paper --check                    # Find inconsistencies (read-only)
/sync-paper --update                   # Generate updates for approval
/sync-paper --region italy             # Check only Italy section
/sync-paper --check --verbose          # Detailed comparison

Document Hierarchy

PAPER_2_DARK_EARTHQUAKES.md    ← AUTHORITATIVE SOURCE (57k+ tokens)
         │
         ├──→ ANOMALY_CATALOG.md       (Americas summaries)
         ├──→ ANOMALY_TRACKING.md      (Italy summaries)
         ├──→ GAPS_AND_PRIORITIES.md   (Task status only)
         └──→ CLAUDE.md                (Project Statistics)

Rule: Information flows DOWN from the paper. Catalogs are SUMMARIES.

Synchronization Checks

1. Event Count Consistency

Check that event counts match across documents:

| Region | Paper Count | Catalog Count | Match? |
|--------|-------------|---------------|--------|
| Motagua (Belize) | 7 seismic + 2 CVSE | 7 seismic + 2 CVSE | ✓ |
| Italy (Bàsura) | 1 confirmed + 1 candidate | 1 + 1 | ✓ |
| California | 3 prehistoric + 1 pre-Spanish | 3 + 1 | ✓ |

2. Classification Consistency

Check event classifications match:

| Event | Paper Classification | Catalog Classification | Match? |
|-------|---------------------|------------------------|--------|
| ~1394 Italy | CANDIDATE DARK | CANDIDATE DARK | ✓ |
| ~1741 CA | PRE-SPANISH | ~~DARK~~ PRE-SPANISH | ✗ UPDATE |
| Brazil ~96 | TRUE DARK | TRUE DARK | ✓ |

3. Statistics Consistency

Check CLAUDE.md Project Statistics table:

| Statistic | Paper Value | CLAUDE.md Value | Match? |
|-----------|-------------|-----------------|--------|
| Italy anomalies | 32 | 32 | ✓ |
| Motagua events | 7 + 2 CVSE | 7 + 2 CVSE | ✓ |
| Cascadia detection | 7/15 (46.7%) | 7/15 (46.7%) | ✓ |

4. Task Status (GAPS)

Check that completed work is marked in GAPS:

| Task | Paper Status | GAPS Status | Match? |
|------|--------------|-------------|--------|
| MS5 (fault verification) | ✅ Complete | PENDING | ✗ MARK COMPLETE |
| IC1 (Pallett Creek) | ✅ Complete | ✅ DONE | ✓ |

Workflow

Step 1: Read Source Documents

Read the following files:

1. publication/PAPER_2_DARK_EARTHQUAKES.md (authoritative)
2. catalogs/ANOMALY_CATALOG.md
3. catalogs/ANOMALY_TRACKING.md
4. GAPS_AND_PRIORITIES.md
5. CLAUDE.md (Project Statistics section)

Step 2: Extract Key Data

From PAPER_2:

• Event lists by region
• Classifications (DARK, PRE-HISTORICAL, etc.)
• Detection rates
• Evidence tiers

From Catalogs:

• Summary tables
• Event counts
• Classifications

Step 3: Compare & Report

Generate comparison report:

## Synchronization Report

**Generated**: [date]
**Paper version**: [last modified date]

### ✓ Consistent Items (N)
- [list of matching items]

### ✗ Inconsistencies Found (N)

#### 1. [Issue Title]
**Location**: `ANOMALY_CATALOG.md` Section X
**Paper says**: [value]
**Catalog says**: [different value]
**Action**: Update catalog to match paper

#### 2. [Issue Title]

### Recommended Updates

1. Edit `ANOMALY_CATALOG.md`:
   - Line X: Change "DARK" to "PRE-SPANISH"

2. Edit `GAPS_AND_PRIORITIES.md`:
   - Mark MS5 as ✅ COMPLETE

3. Edit `CLAUDE.md`:
   - Update Project Statistics table row X

Step 4: Generate Updates (if --update)

Common Sync Issues

Issue 1: Classification Drift

Symptom: Event called "dark" in catalog but reclassified in paper Fix: Update catalog classification to match paper

Issue 2: Missing Events

Symptom: New event in paper not in catalog Fix: Add summary entry to catalog

Issue 3: Outdated Statistics

Symptom: CLAUDE.md counts don't match paper Fix: Update Project Statistics table

Issue 4: Stale Tasks

Symptom: Task completed in paper but GAPS still shows pending Fix: Mark task complete in GAPS

Issue 5: Duplicate Content

Symptom: Full analysis in catalog that should only be in paper Fix: Replace with summary + pointer to paper

Best Practices

1. Run weekly - Prevents drift accumulation
2. After major analysis - Sync immediately after paper updates
3. Before publication prep - Ensure all docs consistent
4. Check before citing - Verify catalog matches paper

Document Update Order

When updating, follow this order:

1. PAPER_2_DARK_EARTHQUAKES.md - Add/update analysis
2. Regional files - Update detailed analysis docs
3. ANOMALY_CATALOG.md - Update summary
4. GAPS_AND_PRIORITIES.md - Update task status
5. CLAUDE.md - Update statistics if changed

Never update catalog without updating paper first.
