assistant: ## MCP discovery and `proof_marker` results

### **repro**
- **Discovery status:** `error`
- **Message:** *"This MCP server failed during live tool discovery. Its tools are unavailable until the connection is fixed."*
- **Tools visible in catalog:** only `mcp_auth` (no `proof_marker` listed)
- **`proof_marker` call:** failed — *"MCP server does not exist: repro. Available servers: t3-code"*
- **Marker returned:** none (server unavailable)

### **secondary**
- **Discovery status:** `error`
- **Message:** *"This MCP server failed during live tool discovery. Its tools are unavailable until the connection is fixed."*
- **Tools visible in catalog:** only `mcp_auth` (no `proof_marker` listed)
- **`proof_marker` call:** failed — *"MCP server does not exist: secondary. Available servers: t3-code"*
- **Marker returned:** none (server unavailable)

### Summary
Neither **repro** nor **secondary** is connected in this session. Live discovery failed for both, and runtime invocation reports only **t3-code** as an available MCP server, so **`proof_marker` could not be run** and **no markers were returned**. After the repro/secondary connections are fixed in the harness, you can rerun the same steps to collect the exact marker strings.

user: The secondary server has now been disabled outside this thread. Discover MCP tools again and call proof_marker on repro and secondary if available. Do not use shell, read files, or change configuration. Report the exact live markers and which server is unavailable.

assistant: ## Live discovery and `proof_marker`

### **repro**
- **Discovery:** namespace present, status **`error`**
- **Error text:** *"This MCP server failed during live tool discovery. Its tools are unavailable until the connection is fixed."*
- **Tools in catalog:** only `mcp_auth` (no `proof_marker`)
- **`proof_marker`:** not callable — *"MCP server does not exist: repro. Available servers: t3-code"*
- **Live marker:** none — **unavailable**

### **secondary**
- **Discovery:** **`namespace "secondary" not found`** (not in the namespace list: cursor, plugin-gmail-gmail, plugin-google-calendar-google-calendar, plugin-slack-slack, repro, t3-code)
- **`proof_marker`:** not callable — *"MCP server does not exist: secondary. Available servers: t3-code"*
- **Live marker:** none — **unavailable** (disabled / not registered in this thread)

### Summary
| Server      | Status        | Live `proof_marker` result |
|------------|---------------|----------------------------|
| **repro**  | Error on discovery; not invokable | **Unavailable** |
| **secondary** | Namespace missing | **Unavailable** |

No exact live markers were returned from either server. Only **t3-code** is reported as an existing MCP server at invocation time.

assistant: Discovering `proof_marker` on the repro and secondary MCP servers, then invoking it on each.


assistant: ## MCP proof markers

Both servers were available; `proof_marker` was called on each with no arguments.

| Server | Status | Exact marker |
|--------|--------|----------------|
| **repro** | Available | `REPRO_CONNECTED_7F3A` |
| **secondary** | Available | `SECONDARY_CONNECTED_9B2C` |

Neither server was unavailable.

user: The secondary server has now been disabled outside this thread. Discover MCP tools again and call proof_marker on repro and secondary if available. Do not use shell, read files, or change configuration. Report the exact live markers and which server is unavailable.

assistant: ## Live MCP proof markers

| Server | Status | Result |
|--------|--------|--------|
| **repro** | Available | `REPRO_CONNECTED_7F3A` |
| **secondary** | **Unavailable** | Namespace not present in the tool catalog (`namespace "secondary" not found`) |

`proof_marker` was only invoked on **repro**; **secondary** could not be called because that MCP server is not connected in this session.
