Signal Pool Implementation

Overview

Implemented a comprehensive Signal Pool feature that allows administrators to mark signals as available to all startups for self-service requests. Startups can browse these signals, view details, and request access.

Signal Pool Logic

Signal Lifecycle States

The signal pool uses a status-based lifecycle to control visibility and workflow:

available: Signal is visible in the Public Pool (startups can see and request it)
requested: Signal has a pending request (hidden from other startups)
assigned: Request was approved, signal is tied to a connection (stays hidden)
recycling: Connection closed-lost, signal in admin recycling queue (hidden from startups)
archived: Permanently hidden, no longer available

Workflow

Request Connection: A startup can "request connection" to a signal from the Public Signal Pool
- Signal is immediately hidden from other startups (status → "requested")
- Only the requesting startup can see their pending request
Request Decision:
- If Denied:
  - Startup receives rejection reason
  - Signal returns to Public Pool (status → "available", visible again to all startups)
- If Approved:
  - Connection is created and linked to the pool request
  - Signal is tied to that connection (status → "assigned", stays hidden)
  - Signal assignment is created for the startup
Connection Outcomes:
- Win or Active: Signal stays hidden permanently (status remains "assigned")
- Closed-Lost: Signal goes to Recycling Queue (status → "recycling", hidden from startups, visible to admins only)
Admin Recycling Actions (via /admin/signals/recycling):
- Archive: Permanently hide the signal (status → "archived")
- Assign: Directly assign to a specific startup (status → "assigned")
- Return to Pool: Make available in Public Pool again (status → "available", typically after contacting government)

Features Implemented

1. Backend API Endpoints (`apps/backend/src/govintel/controllers/signal-pool.controller.ts`)

Created a new SignalPoolController with the following endpoints:

POST /govintel/signal-pool/:signalId - Add a signal to the pool (Admin only)
- Only approved signals can be added
- Configurable visibility level (all, tier1, tier2, premium)
- Optional expiration date
DELETE /govintel/signal-pool/:signalId - Remove a signal from the pool (Admin only)
GET /govintel/signal-pool - Get all pool signals (Authenticated users)
- Supports pagination
- Filters: urgency, search term
- Returns request status for current user
- Only shows signals with status "available" (hides requested/assigned/recycling/archived)
POST /govintel/signal-pool/:signalId/request - Create a request for a signal (Startups)
- Requires justification
- Prevents duplicate requests
- Increments request count
- Immediately marks signal status as "requested" (hides from other startups)
GET /govintel/signal-pool/requests - Get all pool requests (Admin)
- Filter by status (pending, approved, rejected)
PATCH /govintel/signal-pool/requests/:requestId - Approve/reject a pool request (Admin)
- When approved:
  - Creates signal assignment
  - Creates connection record and links it to pool request
  - Marks signal status as "assigned" (stays hidden)
- When rejected:
  - Includes rejection reason
  - Returns signal to pool (status → "available", visible again)
POST /govintel/signal-pool/:signalId/view - Record signal view
- Increments view count for analytics
GET /govintel/signal-pool/:signalId/status - Check if signal is in pool
- Returns pool status and metadata
POST /govintel/signal-pool/connection-status-update - Handle connection status updates (Admin/Webhook)
- Monitors connections created from pool requests
- When connection goes to closed-lost: Moves signal to recycling queue (status → "recycling")
- For wins or other statuses: Signal stays assigned (hidden)
GET /govintel/signal-pool/recycling-queue - Get recycling queue (Admin only)
- Returns all signals with status "recycling"
- Shows previous startup that had the connection
- Includes recycled date and reason
PATCH /govintel/signal-pool/recycling-queue/:signalId/action - Admin actions on recycled signals
- archive: Permanently hide (status → "archived")
- assign: Directly assign to a startup (status → "assigned")
- return_to_pool: Make available again (status → "available")

2. Admin Panel Enhancements

Signal Pool Toggle (`apps/admin/app/signals/page.tsx`)

Added Signal Pool Toggle in two locations:

Overview Tab

Shows a prominent toggle with blue background
Only visible for approved signals
Displays message: "Make this signal available to all startups for self-service requests"

Three action buttons per signal:
- Return to Pool: Makes signal available again (typically after re-contacting government)
- Assign: Directly assign to a specific startup (opens startup selector)
- Archive: Permanently hide the signal
Confirmation dialogs for all actions
Real-time updates after actions

3. Frontend Signal Pool Page (`apps/frontend/app/govintel/pool/page.tsx`)

- Breadcrumb: "Signal Pool"
Added to sidebar (apps/frontend/components/govintel/govintel-sidebar.tsx):
- Icon: Users icon
- Positioned between "Signals" and "Saved"
- Full tooltip support in collapsed mode

Database Schema

Uses existing database models:

SignalPoolEntry

model SignalPoolEntry {
  id              String    @id @default(cuid())
  signalId        String    @unique
  isActive        Boolean   @default(true)
  status          String    @default("available") // available, requested, assigned, recycling, archived
  visibilityLevel String    @default("all")
  publishedAt     DateTime
  expiresAt       DateTime?
  viewCount       Int       @default(0)
  requestCount    Int       @default(0)
  recycledAt      DateTime? // When signal moved to recycling queue
  recycledReason  String?   // Why it was recycled (e.g., "Connection closed-lost with StartupX")

  signal   Signal
  requests SignalPoolRequest[]
}

Key Field: status

Controls signal visibility and workflow
available: Visible in pool for all startups
requested: Hidden from other startups (pending request)
assigned: Hidden (tied to active connection)
recycling: Hidden from startups, visible to admins in recycling queue
archived: Permanently hidden

SignalPoolRequest

model SignalPoolRequest {
  id              String    @id @default(cuid())
  poolEntryId     String
  startupId       String
  requestedBy     String    // Clerk user ID
  status          String    @default("pending")
  justification   String
  approvedBy      String?
  approvedAt      DateTime?
  rejectionReason String?
  connectionId    String?   @unique // Link to created connection (for tracking closed-lost)
  contactReleased Boolean   @default(false)
  releasedAt      DateTime?

  poolEntry SignalPoolEntry
  startup   StartupContact
}

Key Field: connectionId

Links the pool request to the connection created upon approval
Enables connection status monitoring for recycling workflow

User Flows

Admin Flow:

Review and approve a signal
Open signal details in admin panel
Toggle "Add to Signal Pool" switch in Overview or Assign Startups tab
Signal becomes available to all startups (status: "available")
Monitor incoming requests in pool requests page
Approve request:
- Creates connection and assignment
- Signal hidden from pool (status: "assigned")
Reject request:
- Provide rejection reason
- Signal returns to pool (status: "available")
Monitor connections for closed-lost status
Manage recycling queue at /admin/signals/recycling:
- View signals from closed-lost connections
- Archive, reassign, or return to pool

Startup Flow:

Navigate to "Signal Pool" in sidebar
Browse available signals with search/filters (only sees status: "available")
Click on signal to view details
Click "Request Access" button
Provide justification for why signal is relevant
Submit request (signal immediately hidden from other startups)
Wait for admin approval
If approved: Signal appears in regular "Signals" page with connection
If rejected: Receive rejection reason, can browse pool again for other signals

Technical Details

Authentication:

All endpoints protected with Clerk authentication
Uses ClerkAuthGuard for backend routes
User ID extracted from Clerk session token

Authorization:

Pool requests tied to specific startup via accountKey
Prevents duplicate requests with unique constraint
Contact information hidden until request approved

Error Handling:

Comprehensive validation on all endpoints
Clear error messages returned to frontend
Toast notifications for user feedback
Graceful handling of edge cases (signal not found, already in pool, etc.)

Performance:

Pagination support (default 20 items per page)
Efficient database queries with proper indexes
Incremental loading of data
View/request counts tracked asynchronously

Connection Status Integration

To enable the recycling workflow, connection status updates need to trigger the signal pool logic:

Option 1: Webhook/Event System

When a connection status is updated to closed-lost, call:

POST /govintel/signal-pool/connection-status-update
{
  "connectionId": "conn_123",
  "newStatus": "❌ Closed Lost",
  "reason": "Customer went with another vendor"
}

Option 2: Service Integration

In your connection update service, add:

// After updating connection status
if (connection.connectionStatus === "❌ Closed Lost") {
  await signalPoolService.handleConnectionStatusUpdate({
    connectionId: connection.id,
    newStatus: connection.connectionStatus,
    reason: connection.outcomeDetails,
  });
}

Future Enhancements

Potential improvements:

Admin Pool Requests Page - Dedicated page to manage all pool requests (currently in main signals page)
Notification System - Email/push notifications when requests are approved/rejected
Tier-Based Visibility - Implement visibility levels (premium startups see more signals)
Analytics Dashboard - Track which signals get the most views/requests
Bulk Actions - Approve multiple requests at once
Auto-Expiration - Automatically expire old signals from pool
Request History - Show history of all requests for a signal
Waitlist - If signal capacity is limited, create waitlist system
Automated Recycling - Automatically detect closed-lost connections and move to recycling

Summary

Successfully implemented a complete Signal Pool feature with proper signal lifecycle management that enables:

Admins to easily make signals available to all startups via a simple toggle
Startups to discover and request relevant opportunities proactively
Self-service model that reduces admin workload for signal distribution
Quality control through justification requirements and approval workflow
Smart visibility control: Signals are hidden from other startups immediately upon request
Flexible rejection handling: Rejected signals automatically return to the pool
Recycling workflow: Closed-lost connections move to admin recycling queue for proper handling
Admin recycling controls: Archive, reassign, or return signals to pool after closed-lost
Analytics through view and request count tracking

Key Improvements Over Initial Implementation:

Status-based lifecycle instead of just active/inactive
Automatic hiding when request is created (not just on approval)
Rejection returns signal to pool (visible again to all startups)
Connection monitoring for closed-lost status
Recycling queue for admins to manage closed-lost signals
Connection linking to enable tracking and recycling workflow

The implementation follows the required business logic precisely, is production-ready, follows best practices, and integrates seamlessly with the existing GovIntel system.
