<h2>Plan: Tag kg_nodes with nationality_filter via SQL</h2>

<h3>Context</h3>

All kg_nodes currently have <code>nationality_filter = NULL</code> (means &#34;show to everyone&#34;), but every node description is India-specific. We need to tag them with <code>[&#39;IN&#39;]</code> so only Indian users see them.

<h3>Approach</h3>

Run SQL directly against the local database — no Go code changes needed.

<h4>Step 1: Tag all nodes with nationality_filter = [&#39;IN&#39;]</h4>

<pre><code>UPDATE kg_nodes SET nationality_filter = ARRAY[&#39;IN&#39;];
</code></pre>

<h4>Step 2: Tag employment-type-specific nodes</h4>

<pre><code>-- Beckham Law is only for employed (not freelancers)
UPDATE kg_nodes SET employment_type_filter = ARRAY[&#39;employed&#39;]
WHERE title = &#39;Beckham Law (Tax Benefits)&#39;;

-- Company Registration is only for business owners
UPDATE kg_nodes SET employment_type_filter = ARRAY[&#39;business_owner&#39;]
WHERE title = &#39;Company Registration (Business Owners)&#39;;
</code></pre>

<h4>Step 3: Verify</h4>

<pre><code>SELECT COUNT(*) FROM kg_nodes WHERE nationality_filter IS NULL;  -- should be 0
SELECT COUNT(*) FROM kg_nodes WHERE &#39;IN&#39; = ANY(nationality_filter);  -- should be 122
SELECT title, employment_type_filter FROM kg_nodes WHERE employment_type_filter IS NOT NULL;
</code></pre>

That&#39;s it — 3 SQL statements, no code changes.

<div class="collapsible-content"><div class="text-block">Perfect! Now I have all the information needed. Let me provide you with a comprehensive report on the database migration structure.

<h3>Database Migration Structure Report</h3>

<h4><strong>Migration Location</strong></h4>
<ul><li><strong>Directory</strong>: <code>/Users/pj/go/src/github.com/73ai/borderkit/server/migrations/</code></li><li><strong>File Count</strong>: 3 migration files</li></ul>
<h4><strong>Naming Convention</strong></h4>
The project uses a <strong>numbered prefix convention</strong> with the pattern: <code>NNN_description.sql</code>

<strong>Current migrations:</strong>
1. <code>001_auth.sql</code> - Authentication tables (users, auth_state, google_tokens)
2. <code>002_knowledge_graph.sql</code> - Knowledge graph tables (visa_types, consulates, kg_nodes, kg_edges)
3. <code>003_user_state.sql</code> - User state and workflow tables (user_profiles, user_node_progress, user_documents)

<h4><strong>Migration Runner Implementation</strong></h4>

The project uses a <strong>custom built-in Go migration system</strong> (not an external tool like Flyway or Liquibase). The migration runner is implemented in:

<strong>File</strong>: <code>/Users/pj/go/src/github.com/73ai/borderkit/server/internal/db/db.go</code>

<strong>Key Features:</strong>
1. <strong>Migration Tracking</strong>: Uses a <code>schema_migrations</code> table to track which migrations have been applied
2. <strong>Automatic Ordering</strong>: Scans the migrations directory and sorts files alphabetically by name
3. <strong>Idempotent Execution</strong>: Checks if a migration was already applied before executing
4. <strong>Error Handling</strong>: Provides detailed error messages for each step

<strong>Migration Function Signature:</strong>
<pre><code>func Migrate(databaseURL string, migrationsDir string) error
</code></pre>

<h4><strong>How Migrations Are Applied</strong></h4>

<strong>1. Automatic Execution During Server Startup</strong>
In <code>/Users/pj/go/src/github.com/73ai/borderkit/server/cmd/main.go</code> (line 78):
<pre><code>if err := db.Migrate(cfg.DatabaseURL, &#34;migrations&#34;); err != nil {
    return fmt.Errorf(&#34;migration failed: %w&#34;, err)
}
</code></pre>

<strong>2. Standalone Migration Mode</strong>
Can be run independently with a command-line flag:
<pre><code>go run cmd/main.go -migrate
</code></pre>

<strong>3. Development Command</strong>
Via Makefile target (line 49-51):
<pre><code>make db-migrate
<h2>Runs: DATABASE_URL=&#34;postgresql://borderkit:borderkit@localhost:5432/borderkit?sslmode=disable&#34; go run cmd/main.go -migrate</h2>
</code></pre>

<h4><strong>Docker Integration</strong></h4>

1. <strong>Production (Dockerfile)</strong>:
<ul><li>Migrations are copied into the Docker image at <code>/app/migrations</code></li><li>Migrations run automatically when the container starts (via the application initialization)</li></ul>
2. <strong>Development (docker-compose.yml)</strong>:
<ul><li>Migrations directory is mounted to PostgreSQL&#39;s init directory: <code>/docker-entrypoint-initdb.d</code></li><li>This allows PostgreSQL to execute them during container startup</li></ul>
<h4><strong>Migration Process Details</strong></h4>

The <code>Migrate()</code> function:
1. Creates a <code>schema_migrations</code> tracking table if it doesn&#39;t exist
2. Reads all <code>.sql</code> files from the migrations directory
3. Sorts files alphabetically (ensuring correct execution order)
4. For each migration:
<ul><li>Checks if already applied (via <code>schema_migrations</code> table)</li><li>Reads the SQL file</li><li>Executes the SQL statements</li><li>Records the migration filename in the tracking table</li><li>Logs the result</li></ul>
<h4><strong>SQL File Content Pattern</strong></h4>

Each migration file contains multiple <code>CREATE TABLE IF NOT EXISTS</code> statements grouped logically by feature. Example from <code>001_auth.sql</code>:
<ul><li><code>users</code> table - Core user records</li><li><code>auth_state</code> table - OAuth state management</li><li><code>google_tokens</code> table - OAuth token storage</li></ul>
The use of <code>IF NOT EXISTS</code> makes migrations idempotent and safe for re-execution.

+## System Design: Research-Synthesize-Validate-Publish Engine
+
+### Overview
+
+The engine has five layers that transform publicly available immigration information into structured, verified knowledge graph data, which then flows to two outputs: SEO landing pages and the in-app workflow.

+### Layer 1: Research Agent (Claude Code)
+
+The research agent is Claude Code itself. No separate service to build or maintain. The workflow:
+
+1. **You prompt Claude Code** with a visa type + consulate + nationality combination
+2. **Claude Code searches the web** using its built-in tools (web search, web fetch)
+3. **Claude Code synthesizes** the information into structured JSON matching the kg_nodes schema
+4. **Claude Code generates a script** to insert/update the data in PostgreSQL
+5. **You review and approve** the output before running the insertion script
+
+This approach means:
+- Zero additional infrastructure to build
+- You control the research quality directly
+- Research happens on your schedule (batch 5-10 visa types per session)
+- No API costs beyond your existing Claude Code usage
+- The research process itself generates the playbook knowledge you need as founder
+
+**When to automate:** Once you&#39;ve researched 20-30 visa types manually and the schema is proven, build a Go CLI tool (`borderkit research spain-d7`) that calls Perplexity Sonar API ($5/1K requests) for automated research runs. But start manual.
+
+**Research output structure:**
+```json
+{

+          ]
+        }
+      ]
+    }
+  ]
+}
+```
+
+### Layer 2: Validation
+
+**Reference-based LLM-as-judge pattern** (not multi-agent debate -- cheaper and more reliable for factual verification):
+
+For each fact the research agent extracts:
+1. **Source grounding**: Re-fetch the cited URL, verify the claim actually appears in the source
+2. **Cross-reference**: Compare against existing knowledge graph data for contradictions
+3. **Official source check**: If a fact doesn&#39;t cite a government source, search for official confirmation
+4. **Confidence calculation**: Composite score based on source authority, corroboration, and recency
+
+When using Claude Code as the research agent, validation happens naturally in the conversation. You can ask: &#34;Now verify each of these facts against the official sources. Re-fetch each URL and confirm the claims.&#34;
+
+**Hallucination detection signals:**
+- Source URL doesn&#39;t exist or returns 404
+- Source exists but doesn&#39;t contain the claimed information
+- Fact contradicts existing verified data in the knowledge graph
+- Multiple research runs produce inconsistent results for the same query
+
+### Layer 3: Review Queue
+
+**Initially: a simple PostgreSQL table viewed through a basic admin page.**
+
+```sql
+CREATE TABLE research_review_queue (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    kg_node_id UUID REFERENCES kg_nodes(id),
+    visa_type_id UUID NOT NULL REFERENCES visa_types(id),
+    review_priority TEXT CHECK (review_priority IN (&#39;p0&#39;,&#39;p1&#39;,&#39;p2&#39;)),
+    review_status TEXT CHECK (review_status IN (&#39;pending&#39;,&#39;approved&#39;,&#39;rejected&#39;,&#39;edited&#39;)) DEFAULT &#39;pending&#39;,
+    ai_confidence REAL,
+    proposed_data JSONB NOT NULL,
+    source_urls TEXT[],
+    reviewer_notes TEXT,
+    reviewed_by TEXT,
+    reviewed_at TIMESTAMPTZ,
+    created_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
+);
+```
+
+**The review process:**
+- P0 items (fees, deadlines): You open the official government page and verify directly
+- P1 items (requirements, processing times): Spot-check the sources cited
+- P2 items (tips, context): Quick scan for obvious errors, approve in batches
+
+**Scale plan:**
+- 50 visa types x ~50 facts each = 2,500 facts
+- At 85% auto-approve rate: 375 items need your review
+- At 15-25 items/day: 2-3 weeks for initial population
+- Ongoing: 20-50 items/week for re-verification and new visa types
+
+### Layer 4: Knowledge Graph Extensions
+
+**New tables added to the existing schema:**
+
+#### `kg_node_sources` (Source Attribution)
+```sql
+CREATE TABLE kg_node_sources (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    kg_node_id UUID NOT NULL REFERENCES kg_nodes(id) ON DELETE CASCADE,
+    source_type TEXT NOT NULL CHECK (source_type IN
+        (&#39;official&#39;,&#39;law_firm&#39;,&#39;news&#39;,&#39;forum&#39;,&#39;ai_synthesized&#39;,&#39;user_submitted&#39;)),
+    source_url TEXT,
+    source_title TEXT,
+    excerpt TEXT,
+    source_authority REAL NOT NULL DEFAULT 0.5,
+    citation_confidence REAL NOT NULL DEFAULT 0.5,
+    collected_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+    last_verified_at TIMESTAMPTZ,
+    expires_at TIMESTAMPTZ,
+    UNIQUE(kg_node_id, source_url)
+);
+```
+
+#### `kg_node_versions` (Audit Trail)
+```sql
+CREATE TABLE kg_node_versions (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    kg_node_id UUID NOT NULL REFERENCES kg_nodes(id) ON DELETE CASCADE,
+    version_number INT NOT NULL,
+    change_type TEXT NOT NULL CHECK (change_type IN
+        (&#39;created&#39;,&#39;updated&#39;,&#39;deprecated&#39;,&#39;superseded&#39;)),
+    previous_values JSONB,
+    change_reason TEXT,
+    changed_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+    UNIQUE(kg_node_id, version_number)
+);
+```
+
+#### `kg_node_community_tips` (User Tips)
+```sql
+CREATE TABLE kg_node_community_tips (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    kg_node_id UUID NOT NULL REFERENCES kg_nodes(id) ON DELETE CASCADE,
+    user_id UUID REFERENCES users(id) ON DELETE SET NULL,
+    display_name TEXT NOT NULL DEFAULT &#39;Anonymous&#39;,
+    tip_text TEXT NOT NULL,
+    is_approved BOOLEAN DEFAULT FALSE,
+    upvotes INT DEFAULT 0,
+    downvotes INT DEFAULT 0,
+    created_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
+);
+```
+
+#### `kg_node_experiences` (Outcome Reports)
+```sql
+CREATE TABLE kg_node_experiences (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    visa_type_id UUID NOT NULL REFERENCES visa_types(id),
+    consulate_id UUID REFERENCES consulates(id),
+    user_id UUID REFERENCES users(id) ON DELETE SET NULL,
+    display_name TEXT NOT NULL DEFAULT &#39;Anonymous&#39;,
+    nationality TEXT,
+    employment_type TEXT,
+    outcome TEXT CHECK (outcome IN (&#39;approved&#39;,&#39;rejected&#39;,&#39;rfe&#39;,&#39;pending&#39;,&#39;withdrawn&#39;)),
+    processing_days INT,
+    application_date DATE,
+    decision_date DATE,
+    experience_text TEXT,
+    tips_for_others TEXT,
+    is_approved BOOLEAN DEFAULT FALSE,
+    created_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
+);
+```
+
+#### Enhanced `kg_nodes` (Temporal Validity)
+```sql
+ALTER TABLE kg_nodes ADD COLUMN valid_from TIMESTAMPTZ NOT NULL DEFAULT NOW();
+ALTER TABLE kg_nodes ADD COLUMN valid_until TIMESTAMPTZ;
+ALTER TABLE kg_nodes ADD COLUMN research_status TEXT
+    CHECK (research_status IN (&#39;draft&#39;,&#39;verified&#39;,&#39;outdated&#39;,&#39;deprecated&#39;))
+    DEFAULT &#39;verified&#39;;
+ALTER TABLE kg_nodes ADD COLUMN last_verified_at TIMESTAMPTZ;
+```
+
+### Layer 5 Path 1: SEO Landing Pages (Astro + Cloudflare Pages)
+
+#### Why Astro
+
+- **Zero JS by default**: Pages ship as pure HTML. Fastest possible load times. Best Core Web Vitals scores.
+- **Data fetching at build time**: Astro calls your Go API during build, generates static HTML. No runtime server needed.
+- **Cloudflare Pages deployment**: Free hosting, global CDN, automatic HTTPS.
+- **Built-in SEO**: Sitemap generation, canonical URLs, meta tags, structured data support.
+- **Rebuild on schedule**: Cron job (GitHub Actions or Cloudflare cron) triggers a rebuild every few days.

+
+#### URL Structure
+
+```
+/visa/{visa-slug}/                                    → Pillar page (overview)
+/visa/{visa-slug}/requirements                        → Requirements hub
+/visa/{visa-slug}/requirements/{nationality}          → Nationality-specific
+/visa/{visa-slug}/consulate/{consulate-slug}/         → Consulate page
+/visa/{visa-slug}/processing-time                     → Processing times

+```
+
+#### Per-Page Content Requirements
+
+| Element | Requirement | Why |
+|---------|------------|-----|
+| Word count | 400-800 words | Below 300 risks thin content penalty |
+| Unique data points | 5+ per page | Differentiate from template |
+| Template text | Under 40% of page | Google penalizes keyword-swapped templates |
+| FAQ entries | 3-5 with schema markup | 3.2x more likely to appear in AI Overviews |
+| Internal links | 5-12 to sibling pages | Hub-and-spoke architecture |
+| Answer capsule | 40-60 words at top | Optimized for AI Overview citation |
+| Last-updated date | Visible on page | Freshness signal |
+| Source citations | Official gov sources | E-E-A-T compliance |
+| Breadcrumb nav | Full path | Schema.org BreadcrumbList |
+
+#### Build &amp; Deploy Pipeline
+
+```
+1. Go API: GET /api/seo/pages
+   → Returns all visa+consulate+nationality combinations with:
+     - Structured data (fees, requirements, processing times)
+     - AI-synthesized narrative content
+     - Community experience summaries
+     - Source citations
+     - FAQ entries
+     - Related page links
+
+2. Astro build:
+   → Fetches data from Go API
+   → Generates HTML for each combination
+   → Generates sitemap.xml (sitemap index if &gt;50K URLs)
+   → Generates schema.org JSON-LD per page
+   → Outputs to /dist
+
+3. Deploy to Cloudflare Pages:
+   → Push /dist to Cloudflare
+   → Automatic CDN distribution
+   → $0 hosting cost
+
+4. Schedule:
+   → GitHub Actions cron: every 3 days
+   → Or trigger manually after knowledge graph updates
+```
+
+#### Scaling Plan
+
+| Phase | Pages | Timeline | Monitor |
+|-------|-------|----------|---------|
+| Pilot | 100 (pillar + top clusters) | Month 1 | Need 70%+ indexation |
+| Phase 1 | 500 pages | Month 2-3 | Engagement metrics |
+| Phase 2 | 2,000 pages | Month 4-6 | Max 30% monthly growth |
+| Phase 3 | 5,000+ pages | Month 6-12 | Prune zero-traffic pages |
+
+#### AIO (AI Overview) Optimization
+
+Pages should be structured for citation in Google AI Overviews:
+
+1. **Answer capsule** at the top: &#34;Indian nationals applying for a Spain D7 visa at the New Delhi consulate need: [5-7 key documents]. Processing typically takes 30-60 days. The visa fee is EUR X.&#34;
+2. **H2/H3 headings** matching question patterns: &#34;What documents are required?&#34;, &#34;How long does processing take?&#34;
+3. **FAQPage schema** with 3-5 questions per page
+4. **Real data and statistics** (AI Overviews favor factual content)
+5. **Fresh content** (85% of citations from content published in last 2 years)
+
+### Layer 5 Path 2: Community Intelligence
+
+#### Privacy Model: Google Auth + Optional Anonymity
+
+- Logged-in users (Google OAuth) can contribute tips and experiences
+- Contributions can be anonymous (display_name = &#34;Anonymous&#34;) or pseudonymous (user-chosen display name)
+- No real name requirement for community contributions
+- Google auth is only for the app (workflow tracking, document management)
+- SEO pages are fully public, no auth required to browse
+- User-contributed content never reveals the user&#39;s Google identity unless they choose to
+
+#### Community Contribution Flow
+
+```
+User completes a workflow stage
+    → Prompt: &#34;Add a tip for others at this step?&#34; (optional)
+    → User writes tip, chooses display name or anonymous
+    → Tip enters moderation queue (is_approved = false)
+    → Founder reviews and approves
+    → Tip appears on the workflow step for future users
+    → Tip also appears on the SEO landing page for that visa+consulate
+
+User completes entire visa journey (Decision stage)
+    → Prompt: &#34;Share your experience to help others?&#34;
+    → Structured form: outcome, processing days, tips
+    → Choose display name or anonymous
+    → Experience enters moderation queue
+    → Approved experiences contribute to aggregate statistics
+    → Statistics power SEO page data points
+```
+
+#### Give-to-Get Model (Future)
+
+Inspired by Glassdoor: users share their timeline/experience to access aggregate community data. This creates the data flywheel:
+- Every consumer becomes a contributor
+- Reduces polarization bias (extreme reviews decrease)
+- Accelerates data accumulation
+
+#### Cold Start Strategy
+
+1. **Founder seeds first 5-10 visa types** from personal experience (Spain D7, Estonia D7, Croatia D7, Thailand, etc.)
+2. **Claude Code researches** and populates knowledge graph for 20-30 more visa types
+3. **SEO pages go live** with AI-synthesized content + source citations
+4. **Early users contribute** tips and experiences through the app
+5. **Community data gradually replaces** AI-synthesized data as the primary source
+6. **Content is clearly labeled**: &#34;Based on official sources&#34; vs. &#34;Based on community reports (X data points)&#34; vs. &#34;User tip by @anonymous&#34;
+
+### Staleness Monitoring
+
+Visa information changes at different rates. The system must detect and handle stale data.
+
+#### Change Frequency Guide
+
+| Information Type | Change Frequency | Re-Research Interval |
+|-----------------|-----------------|---------------------|
+| Visa fees | Annually | Monthly check |
+| Processing times | Continuously | Weekly check |
+| Document requirements | Rarely (major policy changes) | Monthly check |
+| Eligibility criteria | Infrequently | Monthly check |
+| Country restrictions | Unpredictably (executive orders) | Daily news monitoring |
+| Form versions | Annually | Monthly check |
+| Consulate addresses/hours | Rarely | Quarterly check |
+
+#### Staleness Detection
+
+- `last_verified_at` timestamp on every kg_node
+- `valid_until` for facts with known expiration (fee schedules, fiscal year dates)
+- Confidence decay: effective_confidence decreases as time since verification increases
+- User reports: &#34;Flag as outdated&#34; button on community-facing content
+- Scheduled re-research: Claude Code session every week to verify top priority facts
+
+### Database Schema Summary
+
+**New tables (7):**
+1. `kg_node_sources` -- Source attribution with confidence scores
+2. `kg_node_versions` -- Audit trail of changes
+3. `kg_node_community_tips` -- User-contributed tips per step
+4. `kg_node_experiences` -- Structured outcome reports
+5. `research_review_queue` -- Human review pipeline
+6. `seo_pages` -- SEO page metadata and content
+7. `seo_structured_data` -- Schema.org JSON-LD per page
+
+**Enhanced tables (1):**
+- `kg_nodes` -- Added: `valid_from`, `valid_until`, `research_status`, `last_verified_at`
+
+**New API endpoints:**
+- `GET /api/seo/pages` -- Returns all page data for Astro build
+- `GET /api/seo/pages/{slug}` -- Returns single page data
+- `POST /api/profiles/{id}/workflow/nodes/{nodeId}/tips` -- Submit community tip
+- `GET /api/visa-types/{slug}/experiences` -- Get anonymized experiences
+- `POST /api/profiles/{id}/experience` -- Submit outcome report
+- `GET /api/review-queue` -- Admin: pending review items
+- `PUT /api/review-queue/{id}` -- Admin: approve/reject
+
+### Tech Stack Addition
+
+```
+Existing:
+- Frontend: React 19 + TypeScript + Vite + Tailwind CSS v4 + shadcn/ui
+- Backend: Go 1.24 with stdlib net/http
+- Database: PostgreSQL 17
+- Auth: Google OAuth 2.0 with JWT
+
+New:
+- SEO Site: Astro (static site generator)
