Fix Codex history persistence after daemon restart

- Modified loadPersistedHistoryFromDisk() to use sessionId or conversationId as fallback
- Added rollout path and session dir persistence in agent metadata
- Added fallback to default Codex session root when metadata path is empty
- Cleaned up create-agent-modal.tsx (removed 800+ lines of dead code)
- Updated app routing and home-footer cleanup

+# Claude Streaming Regression Investigation
+
+## Status: ROOT CAUSE IDENTIFIED
+
+## Problem
+Claude agent text is garbled/corrupted during streaming, with words cut off and merged incorrectly (e.g., "a" + "check error" instead of "a" + "type" + "check error"). This bug **ONLY appears in long-running agents** during the 2nd+ conversation turn, not during initial agent creation.
+
+## Investigation Timeline
+
+### Phase 1: App-Side Analysis (Passed)
+- Added debug logging to React Native state management
+- Verified Zustand state updates are correct
+- Confirmed FlatList rendering is correct
+- **Conclusion**: Bug is NOT in the app layer
+
+### Phase 2: Server-Side Streaming Analysis (Passed)
+- Added E2E test to verify server sends clean chunks during new agent creation
+- Test passes - server correctly forwards all text_delta chunks from Claude SDK
+- **Conclusion**: Bug is NOT in baseline streaming code
+
+### Phase 3: Long-Running Agent Analysis (IDENTIFIED ROOT CAUSE)
+- Realized the E2E test only tested NEW agents, not long-running scenarios with multiple turns
+- Examined `claude-agent.ts` state management across multiple `stream()` invocations
+- **ROOT CAUSE FOUND** in `claude-agent.ts`
+
+## Root Cause
+
+### Location
+`packages/server/src/server/agent/providers/claude-agent.ts`
+
+### The Bug: Race Condition with Shared State Flags
+
+**File**: `packages/server/src/server/agent/providers/claude-agent.ts`
+
+**Critical Lines**: 480-482 (fire-and-forget call)
+
+```typescript
+// Line 452-503: stream() method
+async *stream(
+  prompt: AgentPromptInput,
+  _options?: AgentRunOptions
+): AsyncGenerator<AgentStreamEvent> {
+  const sdkMessage = this.toSdkUserMessage(prompt);
+  const queue = new Pushable<AgentStreamEvent>();
+  this.eventQueue = queue;
+  // ...
+  
+  // BUG: forwardPromptEvents is not awaited!
+  // This is a fire-and-forget call that allows race conditions
+  this.forwardPromptEvents(sdkMessage, queue).catch((error) => {
+    console.error("[ClaudeAgentSession] Unexpected error in forwardPromptEvents:", error);
+  });
+
+  // Immediately starts consuming from queue while forwardPromptEvents
+  // is still running asynchronously
+  try {
+    for await (const event of queue) {
+      yield event;
+      if (event.type === "turn_completed" || event.type === "turn_failed") {
+        finishedNaturally = true;
+        break;
+      }
+    }
+  } finally {
+    // ...
+  }
+}
+```
+
+### The Mechanism: Shared State Across Turns
+
+In a long-running agent with multiple turns:
+
+1. **Turn 1**: User sends message
+   - `stream()` called, creates generator instance 1
+   - `forwardPromptEvents()` async method starts running (not awaited)
+   - Flags `streamedAssistantTextThisTurn` and `streamedReasoningThisTurn` reset to false (line 769-770)
+   - Stream events arrive, set flags to true
+   - Final "assistant" message arrives, uses flag to suppress duplicate (line 824)
+
+2. **Turn 2** (while Turn 1 is still processing): User sends another message
+   - `stream()` called AGAIN, creates generator instance 2
+   - Both generator instances share the **SAME ClaudeAgentSession object** with **SAME instance variables**
+   - `forwardPromptEvents()` for Turn 2 resets the flags (line 769-770)
+   - BUT if Turn 1's `forwardPromptEvents()` is still running, its stream_events are STILL coming in
+   - The flag changes are now SHARED between both stream operations
+
+### The Garbled Text Result
+
+When flags get mixed up between concurrent `forwardPromptEvents()` calls:
+
+1. Turn 2's `forwardPromptEvents()` resets `streamedAssistantTextThisTurn = false` (line 769)
+2. Turn 1 is still streaming text_deltas and setting `streamedAssistantTextThisTurn = true` (line 1138)
+3. When Turn 1's final "assistant" message arrives, it checks the flag (line 824)
+4. The flag value is UNCERTAIN - it depends on which operation modified it last
+5. If suppression logic fails, text from different chunks could be:
+   - Partially suppressed (causing words to be cut off)
+   - Duplicated (causing merging)
+   - Out of order
+
+## Affected Code Sections
+
+### 1. The Fire-and-Forget Call (Line 480-482)
+```typescript
+this.forwardPromptEvents(sdkMessage, queue).catch((error) => {
+  console.error("[ClaudeAgentSession] Unexpected error in forwardPromptEvents:", error);
+});
+```
+
+**Problem**: No await. The async function runs in the background while the queue iteration starts immediately.
+
+### 2. Shared Flags (Lines 368-369)
+```typescript
+private streamedAssistantTextThisTurn = false;
+private streamedReasoningThisTurn = false;
+```
+
+**Problem**: These are instance variables shared across ALL calls to `stream()` on the same session object.
+
+### 3. Flag Usage in Suppression Logic (Lines 823-826)
+```typescript
+case "assistant": {
+  const timelineItems = this.mapBlocksToTimeline(message.message.content, {
+    suppressAssistantText: this.streamedAssistantTextThisTurn,  // Uses shared flag!
+    suppressReasoning: this.streamedReasoningThisTurn,           // Uses shared flag!
+  });
+```
+
+**Problem**: Reads the shared flag value without synchronization.
+
+### 4. Flag Mutation During Streaming (Lines 1138, 1149)
+```typescript
+if (context === "live") {
+  this.streamedAssistantTextThisTurn = true;  // Mutates shared flag
+}
+// ...
+if (context === "live") {
+  this.streamedReasoningThisTurn = true;  // Mutates shared flag
+}
+```
+
+**Problem**: Mutates shared state without coordination between concurrent operations.
+
+## Why This Wasn't Caught by Tests
+
+The E2E test in commit `e587547` creates a NEW Claude agent and sends messages sequentially to the SAME agent. While messages are sent back-to-back, the test waits for each response to complete (the `runPrompt()` calls don't overlap).
+
+In the actual app during stress testing or rapid input, multiple `stream()` calls could overlap, causing the race condition.
+
+## Proposed Fix
+
+**Move the streaming flags from instance variables to local variables scoped to each `stream()` invocation.**
+
+Replace instance variables:
+```typescript
+// REMOVE THESE
+private streamedAssistantTextThisTurn = false;
+private streamedReasoningThisTurn = false;
+```
+
+Add as parameters to `forwardPromptEvents()` and pass them through the call chain:
+```typescript
+async *stream(...) {
+  // Local variables scoped to THIS invocation
+  let streamedAssistantTextThisTurn = false;
+  let streamedReasoningThisTurn = false;
+  
+  // Pass to forwardPromptEvents
+  this.forwardPromptEvents(sdkMessage, queue, {
+    streamedAssistantTextThisTurn,
+    streamedReasoningThisTurn,
+  }).catch(...);
+}
+
+private async forwardPromptEvents(
+  message: SDKUserMessage, 
+  queue: Pushable<AgentStreamEvent>,
+  flags: { streamedAssistantTextThisTurn: boolean; streamedReasoningThisTurn: boolean }
+) {
+  flags.streamedAssistantTextThisTurn = false;  // Reset only this operation's flags
+  flags.streamedReasoningThisTurn = false;
+  // ... rest of implementation
+}
+```
+
+This ensures each `stream()` invocation has its own isolated flags that can't interfere with concurrent operations.
+
+## Verification Needed
+
+Before this fix is applied:
+1. Write a test that reproduces the race condition (overlapping `stream()` calls)
+2. Verify the fix prevents the race condition
+3. Run existing E2E tests to ensure no regressions
+
+## Summary
+
+The bug is a **classic race condition** caused by:
+1. Non-awaited async function call (fire-and-forget)
+2. Shared mutable state (instance variables)
+3. Multiple concurrent consumers of that state (overlapping `stream()` calls)
+
+This is a threading/concurrency issue, not a text encoding or protocol problem. The fix is to isolate state per operation rather than sharing it at the instance level.

+# Codex history missing after daemon restart
+
+## Root cause
+- Codex MCP history loader only searched a single session root derived from `CODEX_SESSION_DIR` (or metadata), then stopped.
+- In practice the Codex CLI still writes rollouts under the default `~/.codex/sessions` even when a custom session dir is present in metadata, so the lookup could miss the real rollout file after a daemon restart.
+- When the lookup fails, `loadPersistedHistoryFromDisk()` returns an empty timeline, so `streamHistory()` yields nothing and the UI shows an empty conversation.
+
+## Fix
+- Prefer a persisted rollout path if present, but fall back to scanning the default Codex sessions directory when the preferred root has no rollout file.
+- Allow history lookup to use `conversationId` when `sessionId` is missing so resume still works.
+- Persist `codexSessionDir` so future resumes can try the same root first, but always fall back to the default root if it does not contain the rollout file.
+
+## Files touched

   **NOT DONE** (out of scope for layout refactor):
   - Mode selector below input area: Requires significant AgentInputArea refactoring; current mode is inside Agent dropdown which is acceptable UX
 
+- [x] **BUG (CRITICAL)**: Codex agent history not loading after daemon restart.
+
+  **SYMPTOM**: User restarts daemon, opens existing Codex agent, history is EMPTY. This is broken RIGHT NOW despite tests claiming to pass.
+
+  **YOUR JOB**: Fix it. Not write more tests. Not add logging. FIX THE ACTUAL BUG.
+
+  **RULES**:
+  1. If the E2E tests pass but the feature is broken, THE TESTS ARE WRONG. Do not trust them.
+  2. Do NOT add `.skip` or any test workarounds.
+  3. Do NOT report "investigation complete" without a working fix.
+  4. Do NOT blame "flaky tests" or "non-deterministic behavior".
+
+  **DEBUGGING APPROACH**:
+  1. Start fresh: restart daemon, create Codex agent, send messages, verify they appear
+  2. Restart daemon again
+  3. Resume the agent - does history load? If not, WHY?
+  4. Trace the ACTUAL code path:
+     - `codex-mcp-agent.ts`: `loadPersistedHistoryFromDisk()` - is it called? Does it find the file?
+     - What's in `~/.paseo/agents/{id}/history.jsonl`? Does the file exist? Is it populated?
+     - Is `conversationId` being persisted and restored correctly?
+     - Is `historyPending` flag being set correctly on resume?
+  5. Add console.logs if needed to trace execution
+  6. Find the ROOT CAUSE and fix the code
+
+  **SUCCESS CRITERIA**:
+  - Create Codex agent, send 3 messages, get responses
+  - Restart daemon
+  - Resume agent - ALL 3 messages and responses visible
+  - This must work MANUALLY, not just in tests
+
+  **FILES TO INVESTIGATE**:
+  - `packages/server/src/server/agent/providers/codex-mcp-agent.ts`: `loadPersistedHistoryFromDisk`, `recordHistory`, `flushPendingHistory`, constructor resume logic
+  - `packages/server/src/server/agent/agent-manager.ts`: how agents are resumed
+  - Check persistence file location and format
+
+  - **Done (2025-12-25 22:11)**: Fixed Codex history resume to fall back to the default Codex session root when metadata points at an empty session dir, and to accept conversationId when sessionId is missing.
+
+    **WHAT**:
+    1. `packages/server/src/server/agent/providers/codex-mcp-agent.ts:2631-2647` now loads history by sessionId or conversationId and honors metadata rollout/session hints.
+    2. `packages/server/src/server/agent/providers/codex-mcp-agent.ts:2891-2914` persists codexSessionDir alongside conversationId for resume hints.
+    3. `packages/server/src/server/agent/providers/codex-mcp-agent.ts:4184-4267` adds rollout-path loading and default-root fallback when metadata root is empty.
+    4. Reported investigation notes in `REPORT-codex-history-bug.md`.
+
+    **RESULT**:
+    - Manual restart now rehydrates Codex history (snapshot includes prior user/assistant messages).
+
+    **EVIDENCE**:
+    - Manual run: `node --import tsx /tmp/manual-codex-history.ts` → `History events after restart: 12`.
