merge(staging): resolve conflicts + fix 7 test regressions on top of #2061

- Merge origin/staging into fix/canvas-multilevel-layout-ux. 18 files
  auto-merged (mostly canvas/tabs/chat and workspace-server handlers
  the earlier DIRTY marker was stale relative to current staging).

- Fix 7 test failures surfaced by the merge:

  1. Canvas.pan-to-node.test.tsx — mockGetIntersectingNodes was
     inferred as vi.fn(() => never[]); mockReturnValueOnce of a node
     object failed type check. Explicit return-type annotation.

  2. Canvas.pan-to-node.test.tsx + Canvas.a11y.test.tsx — Canvas.tsx
     reads deletingIds.size (new multilevel-layout state). Both mock
     stores lacked deletingIds; added new Set<string>() to each.

  3. canvas-batch-partial-failure.test.ts — makeWS() built a wire-
     format WorkspaceData (snake_case, with x/y/uptime_seconds). The
     store's node.data is now WorkspaceNodeData (camelCase, no wire-
     only fields). Rewrote makeWS to produce WorkspaceNodeData and
     updated 5 call-site casts. No assertions changed.

  4. ConfigTab.hermes.test.tsx — two tests pinned pre-#2061 behavior
     that the PR intentionally inverts:

       a. "shows hermes-specific info banner" — RUNTIMES_WITH_OWN_CONFIG
          now contains only {"external"}, so the banner is no longer
          shown for hermes. Inverted assertion: now pins ABSENCE of
          the banner, with a comment noting the inversion.

       b. "config.yaml runtime wins over DB" — priority reversed:
          DB is now authoritative so the tier-on-node badge matches
          the form. Inverted scenario: DB=hermes + yaml=crewai →
          form shows hermes. Switched test's DB runtime off langgraph
          because the dropdown collapses langgraph into an empty-
          valued "default" option that would hide the win signal.

- No production code changed — this commit is staging merge + test
  realignment only. 953/953 canvas tests pass. tsc --noEmit clean.

+# Give Your AI Agent Browser Superpowers: Chrome DevTools MCP Integration
+
+Every AI agent platform eventually gets asked the same question: "Can it interact with a web interface?" The answer is usually some variant of "sort of — give it your credentials and hope for the best." That's not a real answer. It's a trust fall.
+
+Chrome DevTools MCP changes this. It gives your AI agent a structured, governed interface to a real Chrome browser session — with full **MCP browser automation** capability and an audit trail that actually answers the question: "which agent touched what, and what did it do?"
+
+This post covers what Chrome DevTools MCP is, how Molecule AI's governance layer makes it enterprise-safe, and how to put it to work in your agent fleet.
+
+---
+
+## What is Chrome DevTools MCP?
+
+Chrome DevTools MCP is an integration between the [MCP (Model Context Protocol)](https://modelcontextprotocol.io) and Google Chrome's DevTools Protocol. MCP is a standardized interface layer that lets AI agents connect to external tools with consistent tooling, authentication, and telemetry. The DevTools Protocol is Chrome's native debugging interface — the same interface your browser's developer tools use to inspect pages, capture network traffic, and control the browser.
+
+When you connect an AI agent to Chrome DevTools via MCP, you get:
+
+- **Full CDP access** — navigate, click, type, screenshot, evaluate JavaScript, read network logs, intercept requests, read cookies and local storage
+- **MCP protocol layer** — structured JSON-RPC instead of raw CDP, consistent tool naming, type-safe parameters
+- **Molecule AI governance layer** — org API key attribution, audit logging, session scoping, instant revocation
+
+The third item is what separates this from "use Puppeteer with an API key." It's the difference between browser automation AI agents and browser automation AI agents with a compliance story.
+
+---
+
+## The Browser Problem: Trust Falls and Black Boxes
+
+When most teams give an AI agent browser access, the workflow looks like this:
+
+1. Agent receives a task ("find our competitors' pricing pages")
+2. Agent uses browser credentials to log into Chrome
+3. Agent navigates, reads, screenshots, and reports
+4. Nobody knows exactly what the agent did, which session it used, or whether credentials were exposed
+
+This is a trust fall, not a governance model. The agent *can* do the task. But you have no audit trail if something goes wrong. No way to revoke access if the agent's behavior becomes unexpected. No attribution if you need to trace a call back to a specific integration.
+
+The **MCP governance layer** in Molecule AI addresses all three:
+
+- Every browser action is logged with the org API key prefix that initiated it
+- Chrome sessions are token-scoped — Agent A's session is never Agent B's
+- Revocation is one API call — the key stops working, the session closes, no redeploy required
+
+---
+
+## How MCP Browser Automation Works in Molecule AI
+
+The integration uses Chrome's CDP over a WebSocket connection managed by the MCP server. Molecule AI's MCP server exposes a structured set of tools that map to CDP commands. Your agent calls these tools like any other MCP tool — the same interface whether you're automating Chrome, reading memory, or querying the platform API.
+
+Here's the sequence:
+
+1. **Workspace starts with a Chrome session attached** — the session is scoped to a specific Chrome profile or fresh browser context, isolated from other agents
+2. **Agent calls MCP tools** — `cdp_navigate`, `cdp_click`, `cdp_evaluate`, `cdp_screenshot`, and others are available as structured tools with type-safe parameters
+3. **Every call is audit-attributed** — the org API key prefix (e.g., `mole_a1b2`) is logged with the tool name, parameters, and result for every CDP call
+4. **Session is revocable at any time** — revoke the org API key and the agent loses Chrome access immediately
+
+### AI Agent Browser Control: What You Can Do
+
+**Navigation and interaction:**
+- `cdp_navigate` — navigate to any URL (supports `data:` and `about:` URLs via browser UI)
+- `cdp_click` — click a DOM element by selector
+- `cdp_type` — type text into a focused element
+- `cdp_hover` — hover over a DOM element
+- `cdp_scroll` — scroll an element or the page
+
+**Inspection and debugging:**
+- `cdp_screenshot` — capture a full-page or viewport screenshot
+- `cdp_evaluate` — execute JavaScript in the page context
+- `cdp_get_cookies` / `cdp_set_cookies` — read and write cookies for authenticated sessions
+- `cdp_get_local_storage` / `cdp_set_local_storage` — read and write localStorage
+
+**Network and performance:**
+- `cdp_get_requests` — capture and filter network requests (XHR, fetch, WS)
+- `cdp_block_urls` — block specific URL patterns to simulate adblocked environments
+- `cdp_set_throttle` — throttle network conditions (3G, LTE, offline)
+
+---
+
+## Browser Automation AI Agents: Use Cases That Actually Ship
+
+The Chrome DevTools MCP integration is most useful in workflows where browser state is the source of truth — and where audit attribution matters.
+
+### Automated Lighthouse audits on every PR
+
+A research agent runs a Lighthouse audit against every pull request in your repo. It navigates to the preview URL, captures the performance score, flags regressions below your threshold, and reports to the PM agent. Every audit run is logged with the org API key — your observability team can trace which agent ran which audit and when.
+
+```bash
+# Agent calls cdp_navigate to the PR preview URL
+# Agent calls cdp_evaluate to run Lighthouse inline
+# Agent calls cdp_screenshot to capture the score
+# Agent delegates results to PM workspace
+```
+
+### Visual regression detection
+
+An agent maintains a baseline set of screenshots for your key user flows. On every code change, it navigates to each flow, captures screenshots, and diffs against the baseline. Drift beyond your threshold opens a ticket automatically. The governance layer means your QA team can review the full history of which screenshots were captured, when, and by which agent.
+
+### Auth scraping
+
+An agent reads authenticated browser state from an existing Chrome session — cookies, localStorage, session tokens — and uses that state to authenticate API calls that would otherwise require separate credential management. The session is scoped; the credentials never leave the browser context.
+
+---
+
+## MCP Governance Layer: Why It Matters
+
+The MCP protocol gives you tool connectivity. The governance layer is what makes it enterprise-ready.
+
+### Per-action audit logging
+
+Every CDP call your agent makes generates an audit log entry. The log includes:
+
+- **Org API key prefix** — which integration made the call (e.g., `mole_a1b2`)
+- **Tool name and parameters** — `cdp_navigate(url=https://...)`
+- **Result or error** — success, timeout, or CDP error code
+- **Timestamp and workspace ID** — for timeline reconstruction
+
+This is the audit trail your security team will ask for in the next compliance review. It exists because Molecule AI's MCP server generates it — not because you built a custom logging pipeline.
+
+### Token-scoped Chrome sessions
+
+Chrome sessions are isolated per org API key. When you create an org API key for a specific integration (`lighthouse-reporter`), that key's Chrome session is separate from every other key's session. No credential cross-contamination — Agent A cannot read Agent B's authenticated state because their sessions are isolated at the MCP tool layer.
+
+### Instant revocation without redeployment
+
+If you need to revoke access — the integration is compromised, the agent behavior is unexpected, the contractor relationship ended — you revoke the org API key:
+
+```bash
+curl -X DELETE https://platform.moleculesai.app/org/tokens/<token-id> \
+  -H "Authorization: Bearer <admin-session-token>"
+```
+
+The key stops working immediately. The Chrome session is closed. The agent loses browser access before the next heartbeat. No redeploy, no container restart, no waiting for DNS cache expiration.
+

+
+## Setting Up Chrome DevTools MCP
+
+Chrome DevTools MCP requires a Chrome instance running with the remote debugging port enabled, and a `chromedp` or equivalent CDP client connected through Molecule AI's MCP server.
+
+### Step 1: Enable Chrome remote debugging
+
+Start Chrome with the `--remote-debugging-port=9222` flag:
+
+```bash
+# macOS
+/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome \
+  --remote-debugging-port=9222 \
+  --user-data-dir=/tmp/chrome-debug
+
+# Linux
+google-chrome --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-debug
+```
+
+### Step 2: Configure Molecule AI
+
+In your workspace config, add the Chrome DevTools MCP server URL:
+
+```yaml
+# config.yaml
+mcpServers:
+  - name: chrome-devtools
+    url: "http://localhost:9222"  # CDP WebSocket endpoint
+    transport: cdp
+```
+
+### Step 3: Verify the connection
+
+Your agent can now call CDP tools. Test with a simple navigation:
+
+```
+Agent: navigate to https://example.com and screenshot the page
+```
+
+The audit log should show `cdp_navigate` and `cdp_screenshot` entries attributed to the workspace's org API key prefix.
+
+---
+
+## What the Security Review Looks Like
+
+When your security team asks "what does this integration actually do?", here's the answer:
+
+**What it can do:**
+- Navigate to any URL (with org API key attribution on every navigation)
+- Read and write browser state (cookies, localStorage, session tokens)
+- Screenshot pages and DOM elements
+- Execute JavaScript in the page context
+
+**What it can't do (by default):**
+- Access the host machine beyond the Chrome sandbox
+- Read files outside the browser context
+- Exfiltrate session tokens across session boundaries
+
+**What revocation looks like:**
+- Revoke org API key → immediate session close
+- No redeploy, no agent restart
+- Audit trail shows every action taken before revocation
+
+---
+
+## Browser Automation Governance: The Bigger Picture
+
+Chrome DevTools MCP is one piece of Molecule AI's broader MCP governance story. MCP is a general-purpose protocol — it connects agents to any tool that speaks CDP, stdio, or HTTP. The governance layer applies uniformly: every MCP call gets the same treatment — org API key attribution, audit logging, instant revocation.
+
+This means you can add new MCP integrations — databases, APIs, code execution environments — with the same governance posture. The MCP protocol is the connectivity layer. Molecule AI's MCP governance layer is the control plane.
+
+If you're evaluating AI agent platforms for browser automation governance, the question to ask is not "can it control a browser?" It's "can I audit every action, attribute every call, and revoke access in one step?" Chrome DevTools MCP with Molecule AI's MCP governance layer is the answer to that question.
+
+---
+
+## Get Started
+
+Chrome DevTools MCP is available on all Molecule AI deployments running Phase 30 or later.

+
+<Callout variant="info">
+Chrome DevTools MCP requires Chrome running with the remote debugging port enabled. CDP access is scoped per org API key — multiple agents can share Chrome sessions only if intentionally scoped that way via key design.

+ * Runtime profiles — per-runtime UX metadata.

+ *   3. DEFAULT_RUNTIME_PROFILE.
+ *
+ * Adding a new runtime:
+ *   - If it's fast (≤ 2min cold boot): do nothing, the default catches it.
+ *   - If it's slow: add one entry to RUNTIME_PROFILES below.
+ *   - Long-term: move runtime profiles server-side so this file can shrink.

+
+# The MCP Server List: Which Servers Work With Molecule AI?
+
+The [Model Context Protocol](/docs/guides/mcp-server-setup) (MCP) is an open standard that lets AI agents connect to external tools and data sources through a unified interface. Rather than writing custom code for every tool integration, MCP servers expose resources and tools that any compatible AI agent can discover and call. This MCP server list covers everything you need to find the right integration for your workflow.
+
+Molecule AI supports MCP out of the box. This means any MCP server in the ecosystem — from lightweight reference implementations to enterprise-grade integrations — can be added to a Molecule AI agent with a server configuration. No forks, no wrappers, no compatibility layers required. This page is your practical MCP server list for real-world AI agent workflows.
+
+This guide covers the full MCP server list that matters: reference servers from the MCP spec authors, official integrations from major vendors, server frameworks for building your own, and community-maintained registries where the broader MCP ecosystem publishes new MCP servers every week. Whether you need one MCP server or a stack of them, this MCP server list gives you the starting points for every major category.
+
+---
+
+## What Is an MCP Server?
+
+An MCP server is a process that implements the Model Context Protocol. It runs separately from your AI agent and communicates over stdio or HTTP+SSE. When a compatible AI agent connects, it receives a manifest of available **tools**, **resources**, and **prompts** — no code changes on the agent side.
+
+The MCP specification defines the transport layer and message shapes. The server implementer decides what capabilities to expose. This separation is what makes the MCP ecosystem portable: an MCP server written for one MCP-compatible platform works on any other, including Molecule AI.
+
+The key MCP concepts that every server implements:
+
+- **Tools** — functions the agent can call (e.g., `search_code`, `read_file`)
+- **Resources** — data the agent can read (e.g., repository contents, database schemas)
+- **Prompts** — reusable prompt templates the agent can load
+
+Every MCP server in this list exposes at least one of these three primitives. Most expose tools; a well-designed MCP server also exposes resources. The Model Context Protocol makes all of this possible by providing a shared vocabulary and transport — so MCP servers and the agents that call them don't need to coordinate on anything beyond the protocol itself.
+
+---
+
+## MCP Reference Servers
+
+The [modelcontextprotocol GitHub organization](https://github.com/modelcontextprotocol) maintains a set of reference server implementations. These are canonical examples maintained by the MCP spec authors and are often the best starting point for common integrations. This reference MCP server list is kept up to date with each protocol release.
+
+### Filesystem MCP Server
+
+Provides local file system access. Useful for AI agents that need to read project files, write output, or navigate a codebase.
+
+```json
+{
+  "mcpServers": {
+    "filesystem": {
+      "command": "npx",
+      "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/allowed/directory"]
+    }
+  }
+}
+```
+
+**Molecule AI note:** Configure `allowedDirectories` in the server args to scope filesystem access. Use separate server configs per workspace if you need per-project isolation.
+
+### Git MCP Server
+
+Exposes Git operations — commit history, diffs, branch listings, file contents at any ref. Useful for AI agents doing code review or changelog generation.
+
+```json
+{
+  "mcpServers": {
+    "git": {
+      "command": "uvx",
+      "args": ["mcp-server-git", "--repository", "/path/to/repo"]
+    }
+  }
+}
+```
+
+**Molecule AI note:** Pass the `--repository` flag to scope the server to a specific project. Without it, the server operates on whatever directory the process runs in.
+
+### Memory MCP Server
+
+A vector-backed memory server that persists facts across agent sessions using embeddings. The agent can store key-value facts and retrieve them semantically later.
+
+```json
+{
+  "mcpServers": {
+    "memory": {
+      "command": "node",
+      "args": ["/path/to/memory-server/dist/index.js"]
+    }
+  }
+}
+```
+
+**Molecule AI note:** Combine with Molecule AI's built-in session context for hybrid short-term + long-term memory strategies.
+
+### Brave Search MCP Server
+
+Web search via the Brave Search API. Gives the agent real-time internet access for research tasks.
+
+```json
+{
+  "mcpServers": {
+    "brave-search": {
+      "command": "npx",
+      "args": ["-y", "@modelcontextprotocol/server-brave-search"],
+      "env": {
+        "BRAVE_API_KEY": "your-api-key"
+      }
+    }
+  }
+}
+```
+
+**Molecule AI note:** Set the `BRAVE_API_KEY` as an environment variable in your Molecule AI workspace secrets, not in the server config file.
+
+---
+
+## Official MCP Integrations
+
+Beyond the reference servers, several established products ship MCP-compatible servers. These are production-grade implementations maintained by the vendors. Each MCP integration in this section ships with vendor support and backward-compatibility guarantees.
+
+### Slack MCP Integration
+
+The official Slack SDK includes an MCP server that exposes channels, messages, and thread replies as tools and resources. An agent can post updates, read channel history, or monitor for specific events.
+
+**Use cases:** Team status updates, incident channel posting, cross-team workflow automation.
+
+### GitHub MCP Integration
+
+The GitHub MCP server surfaces repositories, issues, pull requests, and discussions as structured resources. Agents can create issues, comment on PRs, or query code search.
+
+**Use cases:** Automated code review summaries, issue triaging, release note generation.
+
+### AWS KB Retrieval MCP Integration
+
+Amazon's Bedrock Knowledge Bases can be accessed via MCP. Gives agents read access to indexed enterprise documents.
+
+**Use cases:** Internal knowledge base queries, policy document retrieval, compliance checking.
+
+### Google Drive MCP Integration
+
+Read access to Google Drive files and folders. Agents can search documents, read sheet data, or pull slide content.
+
+**Use cases:** Research synthesis from Drive documents, automated reporting from Sheets.
+
+---
+
+## MCP Server Frameworks
+
+If you need a custom MCP integration not covered by existing servers, MCP server frameworks let you build one without implementing the Model Context Protocol from scratch. These frameworks handle the protocol boilerplate so you can focus on your tool's logic. Building your own MCP server is the right call when you have a proprietary data source, an internal API, or a domain-specific tool that isn't covered by the available MCP servers in the ecosystem.
+
+### Python MCP SDK
+
+The official Python implementation. Ideal for data-heavy or ML-adjacent integrations.
+
+```python
+from mcp.server import Server
+from mcp.types import Tool, TextContent
+
+server = Server("my-analytics-server")
+
+@server.list_tools()
+async def list_tools():
+    return [
+        Tool(
+            name="query_analytics",
+            description="Run a query against the analytics database",
+            inputSchema={
+                "type": "object",
+                "properties": {
+                    "sql": {"type": "string", "description": "SQL query to execute"}
+                },
+                "required": ["sql"]
+            }
+        )
+    ]
+
+@server.call_tool()
+async def call_tool(name: str, arguments: dict):
+    if name == "query_analytics":
+        result = run_query(arguments["sql"])
+        return [TextContent(type="text", text=str(result))]
+```
+
+**Molecule AI note:** Package your server as a Docker image and reference it by image URL in your Molecule AI workspace server config for one-command deployment.
+
+### TypeScript MCP SDK
+
+The official Node.js/TypeScript implementation. Best for web-service integrations, API wrappers, and real-time data sources.
+
+### Go MCP Server Framework
+
+A lightweight Go implementation for high-performance or infrastructure-level integrations.
+
+---
+
+## Community MCP Registries
+
+The MCP ecosystem grows through community contributions. These registries index servers by category and are the best places to discover new MCP servers without searching GitHub manually. Bookmark these — the community publishes new MCP servers every week, and these registries stay current.
+
+### awesome-mcp
+
+The canonical community MCP server list. Maintained on GitHub with categorized entries for tools, resources, and prompt servers. Covers everything from production-grade MCP servers to experimental community projects. Start here when you know the category you need but not the specific MCP server.
+
+### Model Context Protocol Registry (registry.mcp.so)
+
+A structured registry that categorizes servers by domain: development, productivity, data, infrastructure. Each entry links to the implementation and documents supported MCP features.
+
+### MCP Hub
+
+A community-curated directory with install commands for each server. Particularly useful for quickly spinning up a new MCP server via `npx` or `uvx`.
+
+---
+
+## How to Install an MCP Server
+
+The exact install steps depend on the server, but most MCP servers follow the same startup patterns. Most servers can be started with a single command:
+
+```bash
+# Via npx (Node.js servers)
+npx -y @modelcontextprotocol/server-filesystem /allowed/path
+
+# Via uvx (Python servers)
+uvx mcp-server-git --repository /path/to/repo
+
+# Via Docker (any server, in an isolated container)
+docker run -v /data:/data my-registry/my-mcp-server --allowed-path /data
+```
+
+Once started, add the MCP server to your Molecule AI workspace configuration:
+
+```json
+{
+  "mcpServers": {
+    "my-server": {
+      "command": "docker",
+      "args": ["run", "--rm", "-v", "/data:/data", "my-registry/my-mcp-server", "--allowed-path", "/data"]
+    }
+  }
+}
+```
+
+**Molecule AI note:** Use Docker-based servers for any MCP integration that requires credentials or filesystem access you don't want to co-locate with the agent process. Molecule AI's workspace isolation handles the container lifecycle automatically.
+
+---
+
+## Choosing the Right MCP Server: A Decision Guide
+
+Not every MCP server belongs in every project. Here's how to evaluate which MCP servers to add to your Molecule AI workspace. The best MCP server is the one that does exactly what your agent needs — nothing more. Extra MCP servers add latency, credential surface, and maintenance burden without adding value.
+
+| Need | Recommended MCP servers |
+|------|------------------------|
+| Read project files | filesystem |
+| Git operations | git |
+| Web search | brave-search |
+| Slack/Teams integration | slack, teams |
+| Cloud infrastructure queries | aws-kb, google-drive |
+| Long-term memory | memory |
+| Custom data source | Build with Python/TypeScript SDK |
+
+**Start narrow.** Add MCP servers as your agent's tasks require them. Each MCP server is a new attack surface and a new failure mode. The Model Context Protocol gives you a consistent interface to manage them all — but you still need to evaluate each MCP server's security posture before adding it to a workspace. Molecule AI's workspace-level server configuration makes it easy to add servers incrementally and revoke access at the workspace boundary.
+
+---
+
+## MCP Server Governance With Molecule AI
+
+Every MCP server your agent can access is a decision about what the agent is permitted to do. Molecule AI gives you controls at the workspace level so you can govern your MCP servers in production:
+
+- **Server allowlisting** — configure exactly which servers can run in a workspace
+- **Environment variable scoping** — API keys used by MCP servers stay in workspace secrets, not in config files
+- **Audit logging** — every tool call made through an MCP server is recorded in the workspace activity log
+- **Workspace isolation** — each workspace runs its server config independently, so one team's servers don't affect another's
+
+This is the governance layer that makes running MCP servers practical in production. A list of MCP servers is only as useful as the controls around them. Molecule AI provides those controls built in.
+
+Get started with MCP on Molecule AI in the [MCP Server Setup Guide](/docs/guides/mcp-server-setup).

+# What's New in Phase 34
+
+**April 30, 2026**
+
+Phase 34 ships four platform features: Partner API Keys (GA), SaaS Federation v2 (GA), Tool Trace observability (GA), and Platform Instructions governance (GA).
+
+---
+
+## Partner API Keys (GA)
+
+Marketplace resellers, CI/CD tooling, and automation platforms can now manage Molecule AI orgs programmatically using scoped, rate-limited, revocable `mol_pk_` API keys. Create orgs, provision workspaces, and revoke access — no browser session required.
+
+Available scopes: `orgs:create`, `orgs:list`, `orgs:delete`, `workspaces:create`, `billing:read`. Pricing tiers [coming soon](https://molecule.ai/pricing). Available on Partner and Enterprise plans.
+
+## SaaS Federation v2 (GA)
+
+Organizations can now collaborate across org boundaries using a structured, auditable trust model. Grant named federation trusts to partner orgs — scoped to specific workspaces and operations — without sharing credentials. Trust relationships are revocable at any time.
+
+Federation v2 uses A2A protocol with embedded federation claims, so cross-org agent handoffs are verifiable at the receiving end. Available on Enterprise plans.
+
+## Tool Trace Observability (GA)
+
+Every A2A response now includes a structured `tool_trace` array in `Message.metadata`. Each entry records the tool called, its inputs, an output preview, and a `run_id` that correctly groups concurrent parallel calls.
+
+Tool Trace is available on all plans. No sidecar service. No sampling. See the [A2A Protocol Reference](/docs/api-protocol/a2a-protocol) for the full schema.
+
+## Platform Instructions Governance (GA)
+
+Policy rules can now be prepended to an agent's system prompt at workspace startup — at the source, before the first token is generated. Rules are scoped to `global` (all workspaces in the org) or `workspace` (a specific workspace only). The `wsAuth`-gated resolve endpoint ensures workspaces can only read their own instructions.
+
+Platform Instructions are available on Enterprise plans. Each instruction is capped at 8KB. Resolved instruction sets are cached at startup to avoid per-turn latency.
+

+
+# Running A2A v1.0 in Production: What the Migration Actually Looks Like
+
+Most organizations writing about A2A v1.0 are writing about what it *will* enable. We're writing about what it *required* — because we've been running it in production since before the Linux Foundation ratified it, and we just completed the migration from `a2a-sdk` 0.3.x to 1.0.0 across our full agent fleet.
+
+This is a practitioner post. No pitch, no benchmark theater. Here's the real diff: four breaking changes, six files, eight smoke test scenarios, and what we learned.
+
+---
+
+## The Context: A2A at Scale in a Production Fleet
+
+Molecule AI is a multi-agent orchestration platform. Every capability in the product — PM, Dev, Research, Marketing — runs as a discrete A2A-speaking workspace. The platform itself is the coordination layer: task delegation, inter-agent communication, fleet health, and audit attribution all route through the A2A protocol.
+
+The fleet is always-on. Agents wake, accept delegations, complete tasks, and go idle — continuously. At peak, we're running concurrent delegations across six to eight active workspaces per session, with each workspace capable of spawning sub-delegations to sibling agents. The a2a-sdk sits at the center of this: every task dispatch, every `delegate_task` call, every heartbeat touches it.
+
+When `a2a-sdk` 1.0.0 shipped with breaking changes, we had no option to defer. With Phase 34 GA targeting April 30, the migration needed to land on `staging` before April 25 — giving us a five-day buffer to validate before launch.
+
+---
+
+## What Changed in a2a-sdk 1.0.0
+
+The SDK's breaking changes were intentional improvements, not incidental rewrites. Here's what actually moved.
+
+### 1. Server bootstrap: `A2AStarletteApplication` is gone
+
+In 0.3.x, you bootstrapped an A2A server with a single class:
+
+```python
+# 0.3.x
+from a2a.server.apps import A2AStarletteApplication
+app = A2AStarletteApplication(agent_executor=executor, agent_card=card)
+```
+
+In 1.0.0, this class was replaced by a Starlette route factory pattern. The `AgentCard` schema also changed — `capabilities` moved from a flat list to a structured object with typed fields:
+
+```python
+# 1.0.0
+from a2a.server.apps import create_a2a_app
+from a2a.types import AgentCard, AgentCapabilities
+
+card = AgentCard(
+    name="my-agent",
+    capabilities=AgentCapabilities(streaming=True, push_notifications=False)
+)
+app = create_a2a_app(agent_executor=executor, agent_card=card)
+```
+
+Why it's better: the factory pattern makes it easier to compose A2A apps into larger ASGI trees — useful if your agent also serves a health check endpoint or a management API on the same process.
+
+### 2. Part construction: positional constructor removed
+
+In 0.3.x, you could pass a `TextPart` positionally:
+
+```python
+# 0.3.x
+from a2a.types import Part, TextPart
+part = Part(TextPart(text="hello"))
+```
+
+In 1.0.0, `Part` uses keyword arguments only:
+
+```python
+# 1.0.0
+part = Part(text="hello")
+```
+
+This is a clean-up: the positional form was ambiguous when `Part` was extended to support `data` and `file` variants. The keyword form is unambiguous and IDE-friendly.
+
+### 3. `TaskState` enum: string constant replaced
+
+```python
+# 0.3.x
+from a2a.types import TaskState
+state = TaskState.canceled
+
+# 1.0.0
+from a2a.types import TASK_STATE_CANCELED
+state = TASK_STATE_CANCELED
+```
+
+The shift from enum member to module-level constant is a minor ergonomic change that aligns with how other A2A state constants are referenced across the SDK. The actual string value is unchanged — this is a rename, not a semantic change.
+
+### 4. `a2a.utils` → `a2a.helpers`
+
+```python
+# 0.3.x
+from a2a.utils import build_text_artifact
+
+# 1.0.0
+from a2a.helpers import build_text_artifact
+```
+
+Module rename. The function signatures are identical; only the import path changed.
+
+---
+
+## The Migration: Six Files, One PR
+
+All four breaking changes were contained in six files:
+
+| File | Changes |
+|------|---------|
+| `workspace/main.py` | `A2AStarletteApplication` → route factory + `AgentCard` restructure |
+| `workspace/a2a_executor.py` | `Part(TextPart(...))` → `Part(text=...)`, `TaskState.canceled` → `TASK_STATE_CANCELED`, `a2a.utils` → `a2a.helpers` |
+| `workspace/hermes_executor.py` | Enum rename + helpers import |
+| `workspace/google-adk/adapter.py` | Enum rename + helpers import |
+| `workspace/cli_executor.py` | `a2a.utils` → `a2a.helpers` |
+| `workspace/tests/conftest.py` | Mock stub updated to `a2a.helpers` |
+
+Total: one PR (`fix/a2a-sdk-v1-migration`), merged to `staging` as commit `35bcad92`. No test failures. No behavior regression.
+
+The migration was deliberately narrow — touching only the A2A bootstrap, part construction, enum references, and import paths. We made no structural changes to executor logic, task handling, or delegation routing in the same PR. This is the right call for a breaking-change migration: keep the semantic diff minimal so any regression is immediately attributable to the SDK change, not to coincidental refactoring.
+
+---
+
+## Validating the Migration: Eight Smoke Scenarios
+
+Before merging, we ran eight smoke scenarios (S-1 through S-8) designed to exercise each layer of the A2A stack under the new SDK:
+
+- **S-1 — Server starts and card is discoverable:** `GET /agent-card` returns a valid `AgentCard` with typed capabilities.
+- **S-2 — Task submission accepted:** `POST /tasks` with a `TextPart` payload returns a `202 Accepted` with a task ID.
+- **S-3 — Task state transitions:** Task progresses through `submitted → working → completed` without state machine errors.
+- **S-4 — Canceled task handling:** Cancellation request sets `TASK_STATE_CANCELED` correctly and is reflected in the task status response.
+- **S-5 — Helpers import resolves:** `build_text_artifact` and related helpers resolve from `a2a.helpers` with no `ImportError`.
+- **S-6 — Part keyword construction:** `Part(text=...)` constructs cleanly; `Part(data=...)` also resolves for binary payloads.
+- **S-7 — Delegation round-trip:** Full `delegate_task` cycle from a peer workspace completes end-to-end through the upgraded executor.
+- **S-8 — Concurrent delegation under load:** Five concurrent delegations across two workspaces complete without race conditions or dropped tasks.
+
+All eight passed on `staging` before the PR merge. S-7 and S-8 are the high-value tests — they're the ones that would catch a regression in the bootstrap or part construction that only surfaces under real inter-agent traffic.
+
+---
+
+## What We'd Do Differently
+
+**Pin the SDK version explicitly in every executor.**  
+We found two executor files where `a2a-sdk` was listed as a loose dependency (`>=0.3.0`). When 1.0.0 shipped with breaking changes, those executors silently picked up the new version on the next `pip install`. For a library with a breaking change boundary at 1.0, lock the version (`==0.3.x` before migration; `==1.0.0` after) and treat the upgrade as a deliberate event, not a passive update.
+
+**Test the `AgentCard` schema change separately.**  
+The `A2AStarletteApplication` removal and the `AgentCard` restructure should have been two separate test cases. We caught the `AgentCard` schema issue during S-1 — but it would have been cleaner as an explicit pre-migration test rather than a discovery during smoke.
+
+**Migrate mock stubs at the same time as production code.**  
+`workspace/tests/conftest.py` was the last file we touched because it wasn't an executor. But stubs that patch `a2a.utils` will throw `ModuleNotFoundError` the moment the production code migrates to `a2a.helpers` and tests run. Update stubs in the same PR, same commit, as the production migration.
+
+---
+
+## What's Next
+
+The `staging` branch is now on `a2a-sdk` 1.0.0. The `main` branch still carries the 0.3.x code — a `staging→main` sync PR is in progress to land the migration on `main` before Phase 34 GA on April 30.
+
+If you're running `a2a-sdk` 0.3.x and planning the 1.0.0 migration, this post is the reference. The four breaking changes are well-contained, the migration is a single PR, and the eight smoke scenarios above will tell you whether the upgrade is clean before you merge.

+# Multi-Tenant Agent Platform: SaaS Federation with Molecule AI
+
+This tutorial walks through setting up a multi-tenant AI agent platform using Molecule AI's SaaS federation layer. You'll provision workspaces for multiple customers from a single control plane, with per-tenant database isolation, credential separation, and agent fleet visualization.
+
+**What this covers:**
+
+- How the control plane provisions tenant workspaces in your AWS account
+- How to onboard a new tenant with isolated Neon database + EC2 security group
+- How to register and inspect a tenant's agent fleet via the platform API
+- How billing and quota controls work at the tenant layer
+
+**Assumptions:** You have a Molecule AI control plane deployed, an AWS account with VPC + subnets available, and a Neon account for branch-per-tenant databases.
+
+---
+
+## What is SaaS federation?
+
+Molecule AI's SaaS federation layer sits between your control plane and the tenant workspaces your customers use.
+
+```
+You (the platform operator)
+  │
+  ├── Control Plane (api.moleculesai.app)
+  │     └─ Provisions: Neon DB branches, EC2 workspaces, security groups
+  │
+  └── Tenant: acme.rocket.chat
+        ├── Workspace: acme-production-1 (EC2, T3)
+        ├── Workspace: acme-production-2 (EC2, T4)
+        └── Neon branch: acme_db → acme's Postgres
+```
+
+Each tenant is a separate organization in Molecule AI. The control plane holds credentials and provisions infrastructure — but each tenant's workspace data lives in their own isolated branch.
+
+---
+
+## Step 1: Onboard a new tenant
+
+Onboarding creates a new org in your platform, provisions a Neon database branch, and sets up an EC2 security group for the tenant's workspaces.
+
+### Via the control plane API
+
+```bash
+# Create a new tenant org
+curl -X POST https://api.moleculesai.app/cp/orgs \
+  -H "Authorization: Bearer $PROVISION_SHARED_SECRET" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "Acme Corp",
+    "slug": "acme",
+    "plan": "pro",
+    "vpc_id": "vpc-0a1b2c3d4e5f6g7h8",
+    "subnet_ids": ["subnet-abc123", "subnet-def456"]
+  }'
+```
+
+Response:
+
+```json
+{
+  "id": "org_7f2a9c",
+  "name": "Acme Corp",
+  "slug": "acme",
+  "plan": "pro",
+  "neon_branch_id": "br-shadowy-7f2a9c",
+  "security_group_id": "sg-0a1b2c3d",
+  "status": "provisioning"
+}
+```
+
+### What gets provisioned
+
+| Resource | How | Who manages |
+|---|---|---|
+| Neon branch `br-shadowy-7f2a9c` | Auto-created by control plane via Neon API | Tenant gets connection string |
+| EC2 security group `sg-0a1b2c3d` | Created with inbound :443 from platform only | Control plane manages rules |
+| Org record in platform DB | Created on first API call | Control plane |
+
+The provisioning step runs asynchronously — poll `/cp/orgs/:slug` until `status: active`.
+
+```bash
+# Poll until active
+until curl -s https://api.moleculesai.app/cp/orgs/acme \
+    -H "Authorization: Bearer $PROVISION_SHARED_SECRET" \
+    | jq -r '.status' | grep -q active; do
+  echo "Still provisioning..."; sleep 10
+done
+echo "Tenant ready"
+```
+
+---
+
+## Step 2: Provision workspaces for the tenant
+
+Once the tenant org is active, workspaces can be created via the tenant's own API — no operator involvement needed.
+
+Each workspace is provisioned as an EC2 instance in the tenant's VPC subnet, behind the tenant's security group. The security group allows inbound :443 from the platform API only.
+
+```bash
+# As the tenant (they use their own org-scoped API key)
+curl -X POST https://acme.moleculesai.app/workspaces \
+  -H "Authorization: Bearer $TENANT_ORG_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "production-agent-1",
+    "role": "Production inference worker",
+    "runtime": "hermes",
+    "tier": 3,
+    "model": "claude-sonnet-4"
+  }'
+```
+
+The control plane handles the EC2 provisioning in the background:
+
+1. Calls `aws ec2 run-instances` in the tenant's VPC subnet
+2. Waits for the instance to boot and register via A2A
+3. Returns the workspace ID and connection details
+
+The tenant sees a workspace appear in their canvas UI within ~60 seconds.
+
+---
+
+## Step 3: Inspect the tenant's agent fleet
+
+From the operator side, you can inspect any tenant's workspaces via the control plane:
+
+```bash
+# List all workspaces for a tenant
+curl https://api.moleculesai.app/cp/orgs/acme/workspaces \
+  -H "Authorization: Bearer $PROVISION_SHARED_SECRET" \
+  | jq '.'
+```
+
+Response:
+
+```json
+{
+  "org": "acme",
+  "workspaces": [
+    {
+      "id": "ws_9b3k1m",
+      "name": "production-agent-1",
+      "runtime": "hermes",
+      "tier": 3,
+      "instance_id": "i-0a1b2c3d4e5f6g7h8",
+      "status": "running",
+      "last_seen": "2026-04-22T09:30:00Z"
+    },
+    {
+      "id": "ws_2n8p4q",
+      "name": "staging-worker",
+      "runtime": "hermes",
+      "tier": 2,
+      "instance_id": "i-1a2b3c4d5e6f7g8h9",
+      "status": "stopped",
+      "last_seen": "2026-04-21T16:00:00Z"
+    }
+  ]
+}
+```
+
+### Fleet-level metrics
+
+```bash
+# Aggregate runtime stats for a tenant
+curl https://api.moleculesai.app/cp/orgs/acme/metrics \
+  -H "Authorization: Bearer $PROVISION_SHARED_SECRET" \
+  | jq '{total_workspaces, active_agents, avg_response_time_ms, total_tasks_dispatched}'
+```
+
+---
+
+## Step 4: Set quota and billing controls
+
+Quotas are enforced at the org level. Set a workspace count limit to prevent runaway provisioning:
+
+```bash
+# Set workspace limit for tenant
+curl -X PATCH https://api.moleculesai.app/cp/orgs/acme \
+  -H "Authorization: Bearer $PROVISION_SHARED_SECRET" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "max_workspaces": 10,
+    "max_tier": 3,
+    "billing_plan": "pro"
+  }'
+```
+
+When a tenant hits their workspace limit, `POST /workspaces` returns `402 Payment Required` with a message pointing them to upgrade.
+
+---
+
+## Step 5: Revoke access for a tenant
+
+If a tenant stops paying or needs to be suspended:
+
+```bash
+# Suspend tenant (revokes their org API key and freezes workspace creation)
+curl -X POST https://api.moleculesai.app/cp/orgs/acme/suspend \
+  -H "Authorization: Bearer $PROVISION_SHARED_SECRET"
+```
+
+This action:
+- Revokes all org-scoped API keys for the tenant
+- Stops new workspace provisioning
+- Keeps existing workspace data intact (you can resume or hard-delete later)
+
+To hard-delete a tenant and all their workspaces:
+
+```bash
+curl -X DELETE https://api.moleculesai.app/cp/orgs/acme \
+  -H "Authorization: Bearer $PROVISION_SHARED_SECRET"
+  -H "Content-Type: application/json" \
+  -d '{"confirm": true, "delete_workspaces": true}'
+```
+
+This terminates all EC2 instances, drops the Neon branch, and removes the org record. **This is irreversible.**
+
+---
+
+## Security model summary
+
+| Layer | Isolation mechanism | Who manages |
+|---|---|---|
+| Database | Neon branch-per-tenant | Tenant's branch, operator has no direct access |
+| Compute | EC2 in tenant's VPC | Control plane provisions, operator manages SG rules |
+| Credentials | No Fly/API tokens on tenant | All cloud credentials held by control plane |
+| API access | Org-scoped API keys | Tenant manages their own keys; operator has CP-level override |
+| Network | Security group: port 443 from platform only | Control plane manages; tenant can't modify |
+
+---
+
+## What's next
+
+- **Tenant registration UI**: expose a signup flow so customers can self-serve (roadmap: Phase 34)
+- **Scoped roles**: give different team members read-only vs admin access within a tenant org (roadmap: Phase 34)
+- **Usage-based billing**: Meter workspace runtime and forward events to Stripe for custom billing tiers
+
+For runbook-level details on the provisioning flow, see the architecture docs at `docs/architecture/saas-prod-migration-2026-04-19.md`.
+
+For the API reference, see `docs/api-reference.md` — the `/cp/orgs/*` endpoints are documented there.
