release: v3.1.9

* fix: exclude prompt/permission from plan agent config

plan agent should only inherit model settings from prometheus,
not the prompt or permission. This ensures plan agent uses
OpenCode's default behavior while only overriding the model.

* test(todo-continuation-enforcer): use FakeTimers for 15x faster tests

- Add custom FakeTimers implementation (~100 lines)
- Replace all real setTimeout waits with fakeTimers.advanceBy()
- Test time: 104.6s → 7.01s

* test(callback-server): fix race conditions with Promise.all and Bun.fetch

- Use Bun.fetch.bind(Bun) to avoid globalThis.fetch mock interference
- Use Promise.all pattern for concurrent fetch/waitForCallback
- Add Bun.sleep(10) in afterEach for port release

* test(concurrency): replace placeholder assertions with getCount checks

Replace 6 meaningless expect(true).toBe(true) assertions with
actual getCount() verifications for test quality improvement

* refactor(config-handler): simplify planDemoteConfig creation

Remove unnecessary IIFE and destructuring, use direct spread instead

* test(executor): use FakeTimeouts for faster tests

- Add custom FakeTimeouts implementation
- Replace setTimeout waits with fakeTimeouts.advanceBy()
- Test time reduced from ~26s to ~6.8s

* test: fix gemini model mock for artistry unstable mode

* test: fix model list mock payload shape

* test: mock provider models for artistry category

+## Ollama Provider
+
+**IMPORTANT**: When using Ollama as a provider, you **must** disable streaming to avoid JSON parsing errors.
+
+### Required Configuration
+
+```json
+{
+  "agents": {
+    "explore": {
+      "model": "ollama/qwen3-coder",
+      "stream": false
+    }
+  }
+}
+```
+
+### Why `stream: false` is Required
+
+Ollama returns NDJSON (newline-delimited JSON) when streaming is enabled, but Claude Code SDK expects a single JSON object. This causes `JSON Parse error: Unexpected EOF` when agents attempt tool calls.
+
+**Example of the problem**:
+```json
+// Ollama streaming response (NDJSON - multiple lines)
+{"message":{"tool_calls":[...]}, "done":false}
+{"message":{"content":""}, "done":true}
+
+// Claude Code SDK expects (single JSON object)
+{"message":{"tool_calls":[...], "content":""}, "done":true}
+```
+
+### Supported Models
+
+Common Ollama models that work with oh-my-opencode:
+
+| Model | Best For | Configuration |
+|-------|----------|---------------|
+| `ollama/qwen3-coder` | Code generation, build fixes | `{"model": "ollama/qwen3-coder", "stream": false}` |
+| `ollama/ministral-3:14b` | Exploration, codebase search | `{"model": "ollama/ministral-3:14b", "stream": false}` |
+| `ollama/lfm2.5-thinking` | Documentation, writing | `{"model": "ollama/lfm2.5-thinking", "stream": false}` |
+
+### Troubleshooting
+
+If you encounter `JSON Parse error: Unexpected EOF`:
+
+1. **Verify `stream: false` is set** in your agent configuration
+2. **Check Ollama is running**: `curl http://localhost:11434/api/tags`
+3. **Test with curl**:
+   ```bash
+   curl -s http://localhost:11434/api/chat \
+     -d '{"model": "qwen3-coder", "messages": [{"role": "user", "content": "Hello"}], "stream": false}'
+   ```
+4. **See detailed troubleshooting**: [docs/troubleshooting/ollama-streaming-issue.md](troubleshooting/ollama-streaming-issue.md)
+
+### Future SDK Fix
+
+The proper long-term fix requires Claude Code SDK to parse NDJSON responses correctly. Until then, use `stream: false` as a workaround.

+| `artistry`           | `google/gemini-3-pro-preview` (max)| Highly creative/artistic tasks, novel ideas                          |

+### ⚠️ Critical: Model Resolution Priority
+
+**Categories DO NOT use their built-in defaults unless configured.** Model resolution follows this priority:
 
 ```
-// Via delegate_task tool
-delegate_task(category="visual", prompt="Create a responsive dashboard component")
-delegate_task(category="business-logic", prompt="Design the payment processing flow")
+1. User-configured model (in oh-my-opencode.json)
+2. Category's built-in default (if you add category to config)
+3. System default model (from opencode.json)
+```
 
-// Or target a specific agent directly
+**Example Problem:**
+
+```json
+// opencode.json
+{ "model": "anthropic/claude-sonnet-4-5" }
+
+// oh-my-opencode.json (empty categories section)
+{}
+
+// Result: ALL categories use claude-sonnet-4-5 (wasteful!)
+// - quick tasks use Sonnet instead of Haiku (expensive)
+// - ultrabrain uses Sonnet instead of GPT-5.2 (inferior reasoning)
+// - visual tasks use Sonnet instead of Gemini (suboptimal for UI)
+```
+
+### Recommended Configuration
+
+**To use optimal models for each category, add them to your config:**
+
+```json
+{
+  "categories": {
+    "visual-engineering": { 
+      "model": "google/gemini-3-pro-preview"
+    },
+    "ultrabrain": {

+    },
+    "writing": { 
+      "model": "google/gemini-3-flash-preview"
+    }
+  }
+}

+**Only configure categories you have access to.** Unconfigured categories fall back to your system default model.

+# Ollama Streaming Issue - JSON Parse Error
+
+## Problem
+
+When using Ollama as a provider with oh-my-opencode agents, you may encounter:
+
+```
+JSON Parse error: Unexpected EOF
+```
+
+This occurs when agents attempt tool calls (e.g., `explore` agent using `mcp_grep_search`).
+
+## Root Cause
+
+Ollama returns **NDJSON** (newline-delimited JSON) when `stream: true` is used in API requests:
+
+```json
+{"message":{"tool_calls":[{"function":{"name":"read","arguments":{"filePath":"README.md"}}}]}, "done":false}
+{"message":{"content":""}, "done":true}
+```
+
+Claude Code SDK expects a single JSON object, not multiple NDJSON lines, causing the parse error.
+
+### Why This Happens
+
+- **Ollama API**: Returns streaming responses as NDJSON by design
+- **Claude Code SDK**: Doesn't properly handle NDJSON responses for tool calls
+- **oh-my-opencode**: Passes through the SDK's behavior (can't fix at this layer)
+
+## Solutions
+
+### Option 1: Disable Streaming (Recommended - Immediate Fix)
+
+Configure your Ollama provider to use `stream: false`:
+
+```json
+{
+  "provider": "ollama",
+  "model": "qwen3-coder",
+  "stream": false
+}
+```
+
+**Pros:**
+- Works immediately
+- No code changes needed
+- Simple configuration
+
+**Cons:**
+- Slightly slower response time (no streaming)
+- Less interactive feedback
+
+### Option 2: Use Non-Tool Agents Only
+
+If you need streaming, avoid agents that use tools:
+
+- ✅ **Safe**: Simple text generation, non-tool tasks
+- ❌ **Problematic**: Any agent with tool calls (explore, librarian, etc.)
+
+### Option 3: Wait for SDK Fix (Long-term)
+
+The proper fix requires Claude Code SDK to:
+
+1. Detect NDJSON responses
+2. Parse each line separately
+3. Merge `tool_calls` from multiple lines
+4. Return a single merged response
+
+**Tracking**: https://github.com/code-yeongyu/oh-my-opencode/issues/1124
+
+## Workaround Implementation
+
+Until the SDK is fixed, here's how to implement NDJSON parsing (for SDK maintainers):
+
+```typescript
+async function parseOllamaStreamResponse(response: string): Promise<object> {
+  const lines = response.split('\n').filter(line => line.trim());
+  const mergedMessage = { tool_calls: [] };
+
+  for (const line of lines) {
+    try {
+      const json = JSON.parse(line);
+      if (json.message?.tool_calls) {
+        mergedMessage.tool_calls.push(...json.message.tool_calls);
+      }
+      if (json.message?.content) {
+        mergedMessage.content = json.message.content;
+      }
+    } catch (e) {
+      // Skip malformed lines
+      console.warn('Skipping malformed NDJSON line:', line);
+    }
+  }
+
+  return mergedMessage;
+}
+```
+
+## Testing
+
+To verify the fix works:
+
+```bash
+# Test with curl (should work with stream: false)
+curl -s http://localhost:11434/api/chat \
+  -d '{
+    "model": "qwen3-coder",
+    "messages": [{"role": "user", "content": "Read file README.md"}],
+    "stream": false,
+    "tools": [{"type": "function", "function": {"name": "read", "description": "Read a file", "parameters": {"type": "object", "properties": {"filePath": {"type": "string"}}, "required": ["filePath"]}}}]
+  }'
+```

+> **ZERO USER INTERVENTION PRINCIPLE**: All acceptance criteria MUST be executable by agents.
+
+- MUST: Write acceptance criteria as executable commands (curl, bun test, playwright actions)
+- MUST: Include exact expected outputs, not vague descriptions
+- MUST: Specify verification tool for each deliverable type (playwright for UI, curl for API, etc.)
+- MUST NOT: Create criteria requiring "user manually tests..."
+- MUST NOT: Create criteria requiring "user visually confirms..."
+- MUST NOT: Create criteria requiring "user clicks/interacts..."
+- MUST NOT: Use placeholders without concrete examples (bad: "[endpoint]", good: "/api/users")
+
+Example of GOOD acceptance criteria:
+\`\`\`
+curl -s http://localhost:3000/api/health | jq '.status'
+# Assert: Output is "ok"
+\`\`\`
+
+Example of BAD acceptance criteria (FORBIDDEN):
+\`\`\`
+User opens browser and checks if the page loads correctly.
+User confirms the button works as expected.
