+Everything below serves three jobs: **Investigate** the failure, **Recover** the messages, **Prevent** the repeat. ServiceHub's deepest and most mature features are built natively for Azure Service Bus.

-### 💀 Dead-Letter Queue Investigation
-Select the **Dead-Letter** tab to inspect failed messages in full. Each DLQ message shows exactly why Azure moved the message, the full error text from the broker, the AI Assessment, and a one-click Replay button to resend it after fixing the root cause.
+### 💀 Dead-Letter Queue Investigation & Recovery
+Select the **Dead-Letter** tab to inspect failed messages in full. Each DLQ message shows exactly why the broker moved it, the full error text, the assessment in plain English, and one-click actions: **Replay** it back to the main queue after fixing the root cause, or **Purge** it permanently (AWS & GCP — Azure's SDK has no reliable single-message delete, so the action is disabled there rather than pretending).
 
 ### 📊 DLQ Intelligence — Persistent History & 30-Day Trends
 DLQ Intelligence automatically scans your dead-letter queues and stores every finding in a local SQLite database — so you can track failures over time, not just during the current session. Features include a 30-day trend chart, auto-categorization (Transient, MaxDelivery, Expired, DataQuality, Authorization), and CSV/JSON exports.

 ¹ Cross-Cloud Trace searches any namespace whose provider is registered in the API's dependency-injection container. Azure is always registered; AWS/GCP registration is disabled by default in this build — use Simulator mode, or register the provider, to exercise AWS/GCP trace search.
-² GCP Pub/Sub supports peeking dead-lettered messages via the subscription's configured dead-letter topic, but not manually moving a message to the DLQ on demand — Pub/Sub dead-lettering is policy-driven via `MaxDeliveryAttempts` on the subscription. Message counts are also unavailable via the Pub/Sub API and are reported as `0`.
+² GCP Pub/Sub dead-lettering is policy-driven via `MaxDeliveryAttempts`; ServiceHub reads the DLQ through the subscription's configured dead-letter topic, and its test tooling moves messages there by republishing through the subscription's dead-letter policy. Message counts are unavailable via the Pub/Sub API and are reported as `0`.
+³ Test tools (send a message, generate realistic test data, push messages to the DLQ) are available only on **DEV** namespaces with a Manage-level connection — never in UAT or production.
 
 ### 🌐 Cross-Cloud Trace
 Connect namespaces from two or more cloud providers and use **Multi-Cloud Trace** to trace a single Correlation ID or message GUID as it routes from Azure $\rightarrow$ AWS $\rightarrow$ GCP (or any combination). The result is a visual routing path diagram, a chronological hop timeline, and a namespace search-coverage panel.

 **How does AI analysis work without an API key?**
 ServiceHub uses client-side heuristic pattern detection — pure JavaScript in your browser. No GPT, no external service, no data exfiltration.
 
+**Can I delete a single message?**
+On AWS (delete by receipt handle) and GCP (acknowledge), yes — the Purge action, guarded by explicit-intent headers and blocked on production namespaces. Azure Service Bus has no reliable single-message delete in the SDK, so ServiceHub disables the action there instead of faking it.

-## Welcome Page
-ServiceHub ships with a public **landing / welcome page** at the root path (`/`) that serves as the entry point for new users. The CTA in the welcome page reads **"Open ServiceHub"** rather than "Demo" to reflect that the hosted application is a fully functional production deployment — not a restricted preview.
+## Roadmap
+
+ServiceHub is built depth-first: make one workflow excellent before adding the next surface.
+
+- **Now (MVP)** — the forensic core across Azure (GA) and AWS/GCP (preview): explore, search, DLQ investigation, replay, purge, send, auto-replay rules, simulator, live updates.
+- **Next** — operational habit: bulk replay/purge with dry-run preview, DLQ triage inbox, live tail, fleet dashboard across namespaces, Slack/Teams alert cards, Docker packaging.
+- **Later** — team & governance: SSO, role-based access, approval workflows for destructive operations, audit export.
