+This is a **standalone Laravel package** (not an application). It registers as a service provider via `Boot.php` and integrates into the Core PHP Framework's event-driven module system.
+
+### Data Flow
+
+1. **Detection** — `VendorUpdateCheckerService` polls registries (GitHub, Gitea, AltumCode) or `WebhookReceiverService` receives push notifications
+2. **Storage** — `VendorStorageService` manages vendor files locally, with S3 cold archival for older versions
+3. **Analysis** — `DiffAnalyzerService` generates file-level diffs, then `AIAnalyzerService` sends grouped diffs to Claude/OpenAI for categorisation
+4. **Task Generation** — AI analysis produces `UpstreamTodo` records with type, priority, effort, and conflict detection
+5. **Action** — `IssueGeneratorService` creates GitHub/Gitea issues; `UptelligenceDigestService` sends email summaries

-### Service Layer
+### Event-Driven Module Registration
 
-Services are registered as singletons in `Boot.php`:
-
-- `VendorStorageService` - File storage (local/S3)
-- `VendorUpdateCheckerService` - Registry polling (Packagist, npm)
-- `DiffAnalyzerService` - Version diff generation
-- `AIAnalyzerService` - Anthropic/OpenAI code analysis
-- `IssueGeneratorService` - GitHub/Gitea issue creation
-- `UptelligenceDigestService` - Email digests
-- `WebhookReceiverService` - Inbound webhook processing
-
-### Event Registration
+The package uses lazy loading — components only boot when the host fires the relevant event:

+### Service Layer
+
+All services are registered as singletons in `Boot::register()`:
+
+- `VendorStorageService` — Local + S3 cold storage with tar.gz archival and SHA256 integrity
+- `VendorUpdateCheckerService` — Registry polling (GitHub releases/tags, Gitea, AltumCode info.php)
+- `DiffAnalyzerService` — Recursive directory diff with transactional DiffCache storage
+- `AIAnalyzerService` — Anthropic Claude / OpenAI with rate limiting, retry, and API key redaction
+- `IssueGeneratorService` — GitHub/Gitea issue creation from todos
+- `UpstreamPlanGeneratorService` — Porting roadmap generation with dependency ordering
+- `AssetTrackerService` — Composer/npm package monitoring and licence tracking
+- `UptelligenceDigestService` — Filtered email digests (daily/weekly/monthly)
+- `WebhookReceiverService` — Provider-specific signature verification (GitHub, GitLab, npm, Packagist)
+
+### Key Model Relationships
+
+`Vendor` is the central entity. Each vendor has many `VersionRelease` records. Comparing two releases produces `DiffCache` entries (file-level changes). AI analysis of diffs generates `UpstreamTodo` items. All operations are logged in `AnalysisLog`.
+
+Vendors support **path mapping** (`mapToHostHub()`) to translate upstream file paths to target repository paths, and **path filtering** (`shouldIgnorePath()`, `isPriorityPath()`) via fnmatch patterns.
+
+### Webhook Architecture
+
+Webhooks use a **circuit breaker** pattern (auto-disable after 10 consecutive failures) and support **secret rotation** with a 24-hour grace period for dual-validation during transitions.
+
+### Rate Limiters
+
+Defined in `Boot.php`: `uptelligence-ai` (10/min), `uptelligence-registry` (30/min), `uptelligence-issues` (10/min), `uptelligence-webhooks` (60/min per endpoint).
