+# API and CLI Integration - Bearer Token Auth
+
+## Summary of Changes
+
+Successfully integrated Bearer token authentication between the HPL CLI and API, enabling the CLI's write operations to work with the admin endpoints.
+
+## Changes Made
+
+### API Changes (lab-api)
+
+**File: `src/routes/adminRoutes.ts`**
+
+1. **Added import** for `requireAuth` middleware:
+   ```typescript
+   import { requireAuth } from "../middleware/requireAuth.js";
+   ```
+
+2. **Updated POST /admin/notes endpoint** to accept Bearer tokens:
+   ```typescript
+   // Changed from:
+   app.post("/admin/notes", requireAdmin, ...)
+
+   // To:
+   app.post("/admin/notes", requireAuth(db), ...)
+   ```
+
+**Why this works:**
+- `requireAuth` middleware supports BOTH session auth (humans in browser) AND Bearer token auth (CLI)
+- Checks session first, then falls back to Bearer token
+- Returns 401 if neither auth method succeeds
+- No breaking changes - browser users still work with sessions
+
+### CLI Changes (the-human-pattern-lab-cli)
+
+**File: `src/types/labNotes.ts`**
+
+Changed field name in `LabNoteUpsertSchema` to match API:
+```typescript
+// Changed from:
+markdown: z.string().min(1),
+
+// To:
+content_markdown: z.string().min(1),
+```
+
+**File: `src/commands/notes/create.ts`**
+
+1. Changed payload field name:
+   ```typescript
+   content_markdown: markdown  // was: markdown: markdown
+   ```
+
+2. Changed endpoint:
+   ```typescript
+   "/admin/notes"  // was: "/lab-notes/upsert"
+   ```
+
+**File: `src/commands/notes/update.ts`**
+
+Same changes as create.ts (field name and endpoint).
+
+**File: `src/commands/notes/notesSync.ts`**
+
+Same changes (field name and endpoint) to keep sync working.
+
+## How Authentication Works Now
+
+### For CLI (Bearer Token)
+```bash
+export HPL_TOKEN="hpl_test_xxxxx"
+hpl notes create --title "Test" --slug "test" --file note.md
+```
+
+Request flow:
+1. CLI sends: `Authorization: Bearer hpl_test_xxxxx`
+2. API `requireAuth` middleware:
+   - Checks session (not present)
+   - Checks Bearer token (present!)
+   - Validates token hash in database
+   - Checks token is active and not expired
+   - Sets `req.auth = { kind: "token", ... }`
+3. Route handler executes
+
+### For Browser (Session)
+User logs in via GitHub OAuth → Session cookie is set → Works as before
+
+Both methods work on the same endpoint!
+
+## Testing the Integration
+
+### 1. Generate an API Token
+
+First, you need a valid Bearer token. This requires session auth to create:
+
+```bash
+# Via API (need to be logged in with session):
+curl -X POST http://127.0.0.1:8001/admin/tokens \
+  -H "Cookie: hpl.sid=..." \
+  -H "Content-Type: application/json" \
+  -d '{
+    "label": "CLI Testing",
+    "scopes": ["admin"],
+    "expires_at": null
+  }'
+```
+
+Or use the browser UI to mint a token.
+
+### 2. Test CLI Create
+
+```bash
+# Set token
+export HPL_TOKEN="hpl_test_YOUR_TOKEN_HERE"
+
+# Override API base to local
+export HPL_BASE_URL="http://127.0.0.1:8001"
+
+# Create a test note
+echo "# Test Note" > test.md
+npm run dev -- notes create \
+  --title "Test Note" \
+  --slug "cli-test-$(date +%s)" \
+  --file test.md \
+  --status draft
+```
+
+Expected: Success! Note created.
+
+### 3. Test CLI Update
+
+```bash
+npm run dev -- notes update cli-test-123456789 \
+  --title "Updated Title" \
+  --markdown "# Updated content"
+```
+
+### 4. Test JSON Output
+
+```bash
+npm run dev -- notes create \
+  --title "JSON Test" \
+  --slug "json-test" \
+  --markdown "# Content" \
+  --json
+```
+
+Should return valid JSON envelope.
+
+## Token Management
+
+### Creating Tokens
+
+Tokens are created via `/admin/tokens` POST endpoint (requires session auth):
+
+```json
+{
+  "label": "My CLI Token",
+  "scopes": ["admin"],
+  "expires_at": null
+}
+```
+
+Returns:
+```json
+{
+  "ok": true,
+  "data": {
+    "token": "hpl_test_xxxxx",  // Raw token (shown once!)
+    "id": "uuid"
+  }
+}
+```
+
+### Token Security
+
+- Raw tokens are never stored (only SHA-256 hash + pepper)
+- Tokens include prefix: `hpl_test_` (dev) or `hpl_live_` (prod)
+- Configurable expiration
+- Can be revoked via `/admin/tokens/:id/revoke`
+- Scoped permissions (currently just "admin")
+
+### Token Storage
+
+**In API database** (`api_tokens` table):
+- id
+- label
+- token_hash (SHA-256 of pepper:token)
+- scopes_json
+- is_active
+- expires_at
+- created_by_user
+- last_used_at
+- created_at
+
+**In CLI config** (`~/.humanpatternlab/hpl.json`):
+```json
+{
+  "apiBaseUrl": "https://api.thehumanpatternlab.com",
+  "token": "hpl_test_xxxxx"
+}
+```
+
+Or via environment variable:
+```bash
+export HPL_TOKEN="hpl_test_xxxxx"
+```
+
+## Error Handling
+
+### 401 Unauthorized
+- No token provided
+- Invalid token (not in database)
+- Expired token
+- Inactive token
+
+### 403 Forbidden  
+- Token lacks required scopes (future feature)
+
+### 400 Bad Request
+- Missing required fields (title, slug)
+- Invalid data
+
+## Benefits of This Approach
+
+✅ **No Breaking Changes**: Browser users still use sessions
+✅ **Secure**: Tokens are hashed, can be revoked, can expire
+✅ **Flexible**: Both auth methods work on same endpoint
+✅ **Clean**: No duplicate endpoints needed
+✅ **Auditable**: Tokens track `created_by_user` and `last_used_at`
+
+## Next Steps
+
+1. Test the integration end-to-end
+2. Create a token via the browser UI or API
+3. Test CLI create/update operations
+4. Verify sync still works
+5. Consider adding token management commands to CLI (`hpl tokens list`, `hpl tokens create`, etc.)
+
