+# Stream Reading Improvements for CI Testing
+
+## Problem Statement
+Tests fail on CI (GitHub Actions) because `stream_select` behavior differs from local environment. The REPL process outputs to stdout, but tests only capture the banner and miss command output. This is likely due to:
+- GitHub Actions TTY limitations
+- Stderr writes that unblock select
+- Different buffering behavior in CI
+
+## Core Considerations
+
+### 1. ✅ Fix the Loop Logic (DONE)
+**Problem**: Current loop exits on first timeout without a prompt, even with longer timeouts.
+**Solution**: Continue polling on timeout instead of breaking. Use overall timeout guard.
+**Status**: Implemented in `ReplOutputReader::readOutput()`
+- Changed `break` to `continue` on timeout without prompt
+- Added overall timeout tracking
+
+### 2. ✅ Environment Configuration (DONE)
+**Solution**: Use .env for local, .env.test for CI with configurable timeouts
+**Status**: Implemented
+- `.env` with 1.5s timeout (local, gitignored)
+- `.env.test` with 5.0s timeout (CI, tracked)
+- ReplOutputReader reads from environment
+
+### 3. ✅ Read from Both stdout AND stderr (DONE)
+**Problem**: GitHub Actions might write to stderr, causing stream_select to unblock, but we only read stdout.
+**Solution**:
+- Pass both `$pipes[1]` (stdout) and `$pipes[2]` (stderr) to stream_select
+- Read from whichever is ready
+- Only append stdout to output (discard stderr noise, or log it)
+**Status**: IMPLEMENTED in `ReplOutputReader::readOutput()`
+- Modified signature to accept `$stderrStream` parameter
+- Loop reads from both streams
+- stderr output logged but not included in return value
+- Updated `ReplSteps::readOutput()` to pass stderr
+
+### 4. ✅ Debug Logging for CI (DONE)
+**Problem**: Can't see what's happening in CI without visibility, but don't want noise on passing tests
+**Solution**: Add conditional debug logging to ReplOutputReader
+**Status**: IMPLEMENTED
+- Buffers log messages instead of immediately outputting
+- Only outputs logs when:
+  - `REPL_DEBUG=true` in .env (always log)
+  - Timeout occurs with no output (indicates failure)
+  - stream_select error occurs
+- Keeps local test output clean (.env has `REPL_DEBUG=false`)
+- CI gets full logs (.env.test has `REPL_DEBUG=true`)
+- Added to `ReplProcessManager::sendInput()` as well
+
+### 5. ✅ Process Management Review (DONE)
+**Current**: Using `proc_open` with pipes, streams set to non-blocking
+**Considerations**:
+- After writing to stdin (`$pipes[0]`), explicitly `fflush($pipes[0])`
+- Consider `fclose($pipes[0])` after all input to signal EOF (may not be appropriate for REPL)
+- Ensure both stdout and stderr are non-blocking
+**Status**: REVIEWED - Already doing `fflush()` after writes
+- Added logging to `sendInput()` to verify bytes written
+
+### 6. 🔮 Sentinel/Test Mode Approach (FUTURE)
+**Alternative**: Instead of guessing prompts, have REPL print a sentinel in test mode
+```php
+// In test mode, REPL prints:
+echo "COMMAND_DONE_MARKER\n";
+```
+Then look for sentinel instead of prompt patterns.
+**Status**: NOT IMPLEMENTED - Requires REPL changes
+**Priority**: LOW - Nice to have, but invasive
+
+### 7. 🔮 Phunkie Streams Solution (FUTURE)
+**Idea**: Extract this into a reusable Phunkie Streams component
+- `Stream\Process\asyncRead($stream, $predicate, $timeout)`
+- Handles non-blocking reads, multiple streams, sentinel detection
+**Status**: NOT IMPLEMENTED
+**Priority**: LOW - After we solve the immediate problem
+
+## Action Items (Prioritized)
+
+### Immediate (Baby Steps)
+1. ✅ Fix loop to continue polling instead of breaking on timeout
+2. ✅ Add .env configuration for timeouts
+3. ✅ Modify `ReplOutputReader::readOutput()` to accept stderr stream
+4. ✅ Update `ReplSteps` to pass stderr to `readOutput()`
+5. ✅ Read from both streams in the loop, only append stdout to output
+6. ✅ Add debug logging (error_log) to see what's happening in CI
+7. ✅ Review `ReplProcessManager` for proper fflush() usage
+8. ⏳ **NEXT**: Test locally to verify changes don't break existing tests
+9. ⏳ **NEXT**: Test on CI with full test suite
+
+### Long Term
+10. Review CI logs to see if stderr reading solves the issue
+11. Consider reducing timeouts if tests are passing consistently
+12. Consider sentinel-based approach for more reliable testing
+13. Extract pattern into Phunkie Streams if successful
+
+## Notes
+- **Don't just increase timeouts** - that makes CI slow and doesn't address root cause
+- **Stderr reading is likely the key** - GitHub Actions might be writing to stderr
+- **Keep local tests fast** - use .env for short timeouts locally
+- **Baby steps** - implement one thing at a time and test
+
+## Current Status
+- Loop logic fixed ✅
+- Environment config added ✅
+- Stderr reading implemented ✅
+- Debug logging implemented with buffering ✅
+- **SENTINEL APPROACH IMPLEMENTED** ✅
+- **LOCAL TESTS**: All 418 scenarios, 2056 steps PASSING in ~18s ✅
+- **NEXT**: Test on CI to verify sentinel approach works in GitHub Actions
+
+## Test Results
+- **Local (PHP 8.4)**: 418 scenarios, 2056 steps - ALL PASSED ✅
+- **CI**: Pending - need to push and test
+
+## Sentinel Approach + Blocking Read Strategy
+
+### The Problem
+GitHub Actions has different TTY/buffering behavior than local environments. The original non-blocking, short-timeout polling approach with `stream_select` would break too aggressively on timeouts, exiting the read loop before all data arrived. This caused tests to only capture the REPL banner, missing actual command output.
+
+### The Solution: Two-Part Fix
+
+#### Part 1: Sentinel Marker (Explicit Ready Signal)
+Instead of guessing when the REPL is ready by detecting prompt patterns, the REPL explicitly prints `__PHUNKIE_READY__` when ready for input.
+
+**REPL side** (`src/Repl/ReplLoop.php`):
+- Added `isTestMode()` to check `REPL_TEST_MODE` environment variable
+- Added `printTestSentinel()` that prints `__PHUNKIE_READY__\n` in test mode
+- Called before each prompt in `replLoopTrampoline()`
+
+**Test side**:
+- `ReplProcessManager` loads `.env` and passes `REPL_TEST_MODE` to child process
+- `ReplOutputReader` detects sentinel instead of prompt patterns in test mode
+- Sentinel is stripped from output before returning to tests
+- `ReplSteps.waitForPrompt()` uses `ReplOutputReader` for consistent detection
+
+#### Part 2: Blocking Read Strategy (Patience Over Speed)
+Changed from aggressive timeout-based polling to blocking reads that wait naturally for data.
+
+**Key changes in `ReplOutputReader::readOutput()`**:
+1. **Longer `stream_select` timeout**: Up to 1 second (vs 50ms) to let data arrive naturally
+2. **No early exits on timeout**: Only breaks when:
+   - Prompt/sentinel found ✅
+   - Overall timeout hit ⏱️
+   - EOF/error encountered ❌
+3. **Calculated remaining timeout**: Uses `min(1.0, remainingTimeout)` for smart waiting
+4. **Smaller read chunks**: 4096 bytes for more incremental reading
+5. **Proper error handling**: Detects EOF and read errors explicitly
+
+**Before (aggressive)**:
+```php
+// 50ms timeout on stream_select
+$result = @stream_select($read, $write, $except, 0, 50000);
+if ($result === 0) {
+    break; // ❌ Exits too early!
+}
+```
+
+**After (patient)**:
+```php
+// Up to 1 second timeout, calculated from remaining time
+$selectTimeout = min(1.0, $remainingTimeout);
+$result = @stream_select($read, $write, $except, $selectTimeoutSec, $selectTimeoutUsec);
+if ($result === 0) {
+    if (self::endsWithPrompt($output)) {
+        break; // ✅ Only exit if we have complete response
+    }
+    continue; // ✅ Keep waiting for data
+}
+```
+
+### Benefits
+- ✅ **Reliable in CI**: Doesn't break early when I/O is slow
+- ✅ **Explicit ready signal**: Sentinel removes guesswork
+- ✅ **Fast locally**: ~18 seconds for 418 scenarios
+- ✅ **Handles slow environments**: Waits patiently up to overall timeout
+- ✅ **Clean output**: Sentinel stripped automatically
+- ✅ **Proper error handling**: Detects EOF and errors gracefully
+
+### Configuration
+- `.env` (local): `REPL_TEST_MODE=true`, `REPL_OUTPUT_TIMEOUT=1.5`
+- `.env.test` (CI): `REPL_TEST_MODE=true`, `REPL_OUTPUT_TIMEOUT=5.0`
+
+### Files Modified
+- `src/Repl/ReplLoop.php` - Sentinel printing
+- `tests/Acceptance/Support/ReplProcessManager.php` - Environment passing
+- `tests/Acceptance/Support/ReplOutputReader.php` - **Blocking read strategy + sentinel detection**
+- `tests/Acceptance/ReplSteps.php` - Use ReplOutputReader in test mode
+- `.env` and `.env.test` - Configuration
