# Verification Report: Pipeline Logging Quality

**Date**: 2025-11-28
**Verified By**: AI Lead Coder (Opus)
**Status**: COMPLETE - All hypotheses tested

## Pre-Implementation Hypotheses & Evidence

Per teamsop.md Section 1.3 (Prime Directive), all beliefs about the codebase must be verified by reading source code before implementation.

### Hypothesis 1: Schema module prints at import time

**Hypothesis**: The `[SCHEMA] Loaded 155 tables` message is printed at module import time in `schema.py`.

**Verification**: CONFIRMED

**Evidence** (schema.py:72-73):
```python
assert len(TABLES) == 155, f"Schema contract violation: Expected 155 tables, got {len(TABLES)}"
print(f"[SCHEMA] Loaded {len(TABLES)} tables")
```

**Impact**: Every subprocess that imports `theauditor.indexer.schema` will print this message. With 25+ phases running as subprocesses, this creates 20+ duplicate messages.

---

### Hypothesis 2: readthis directory is still being created

**Hypothesis**: The zombie `readthis_dir` code from pipeline.md Phase 0 has not been cleaned up.

**Verification**: CONFIRMED

**Evidence** (pipelines.py:352-353):
```python
readthis_dir = Path(root) / ".pf" / "readthis"
readthis_dir.mkdir(parents=True, exist_ok=True)
```

**Additional Evidence** (pipelines.py:1595-1617):
```python
readthis_final = Path(root) / ".pf" / "readthis"
readthis_final.mkdir(parents=True, exist_ok=True)
# ... file moving logic (shutil.move for pipeline.log and allfiles.md) ...
```

**Impact**: Directory created but adds no value. Files moved there serve no purpose.

---

### Hypothesis 3: run_chain_async prints duplicate COMPLETED

**Hypothesis**: Both `run_chain_async` and the observer print completion messages, causing duplicates.

**Verification**: CONFIRMED

**Evidence** (pipelines.py:237):
```python
print(f"[{status}] {chain_name} ({elapsed:.1f}s)", file=sys.stderr)
```

**Evidence** (events.py:87-91):
```python
def on_parallel_track_complete(self, track_name: str, elapsed: float) -> None:
    if not self.quiet:
        try:
            print(f"[COMPLETED] {track_name} ({elapsed:.1f}s)", flush=True)
```

**Impact**: User sees `[COMPLETED] Track B` twice for each parallel track.

---

### Hypothesis 4: Taint analysis prints directly to stderr

**Hypothesis**: `run_taint_sync()` uses `print(..., file=sys.stderr)` extensively, causing output to appear after asyncio.gather() completes.

**Verification**: CONFIRMED

**Evidence** (pipelines.py:1001-1100, partial sample):
```python
# run_taint_sync() defined at line 1001
print("[STATUS] Track A (Taint Analysis): Running: Taint analysis [0/1]", file=sys.stderr)  # line 1009
print("[TAINT] Initializing security analysis infrastructure...", file=sys.stderr)  # line 1017
print(f"[TAINT]   Found {len(infra_findings)} infrastructure issues", file=sys.stderr)  # line 1032
print("[TAINT] Discovering framework-specific patterns...", file=sys.stderr)  # line 1036
print(f"[TAINT]   Registry now has {stats['total_sinks']} sinks, {stats['total_sources']} sources", file=sys.stderr)  # line 1042
# ... (~15 taint print statements total)
```

**Impact**: Because `run_taint_sync()` runs via `asyncio.to_thread()` (line 1192), its stderr buffer flushes asynchronously. The main loop may print completion messages before taint output appears.

---

### Hypothesis 5: ConsoleLogger exists in events.py

**Hypothesis**: The partial observer implementation `ConsoleLogger` exists and wraps print().

**Verification**: CONFIRMED

**Evidence** (events.py:43-93):
```python
class ConsoleLogger:
    """ASCII-safe console logger (Windows CP1252 compatible).

    This is the DEFAULT observer. It replicates the original 'print' behavior
    exactly, ensuring no visual regression.
    """

    def __init__(self, quiet: bool = False):
        self.quiet = quiet

    def on_phase_start(self, name: str, index: int, total: int) -> None:
        if not self.quiet:
            print(f"\n[Phase {index}/{total}] {name}", flush=True)
    # ... etc
```

**Impact**: `ConsoleLogger` is just print() with extra steps. No buffering, no coordination.

---

### Hypothesis 6: Parallel tracks print STATUS interleaved

**Hypothesis**: Both Track A and Track B print status to stderr while running in parallel.

**Verification**: CONFIRMED

**Evidence** (pipelines.py:189-192) in `run_chain_async`:
```python
print(
    f"[STATUS] {chain_name}: Running: {description} [{completed_count}/{total_count}]",
    file=sys.stderr,
)
```

**Evidence** (pipelines.py:1007-1010) in `run_taint_sync`:
```python
print(
    "[STATUS] Track A (Taint Analysis): Running: Taint analysis [0/1]",
    file=sys.stderr,
)
```

**Impact**: No coordination between tracks = interleaved `[STATUS]` messages.

---

### Hypothesis 7: PipelineObserver protocol exists

**Hypothesis**: A `PipelineObserver` protocol exists in `events.py` that can be extended.

**Verification**: CONFIRMED

**Evidence** (events.py:11-40):
```python
class PipelineObserver(Protocol):
    """Observer interface for pipeline events."""

    def on_phase_start(self, name: str, index: int, total: int) -> None:
        """Called when a phase begins."""
        ...

    def on_phase_complete(self, name: str, elapsed: float) -> None:
        """Called when a phase succeeds."""
        ...
    # ... etc
```

**Impact**: Good foundation. `RichRenderer` can implement this protocol.

---

### Hypothesis 8: pipelines.py has mixed print/observer usage

**Hypothesis**: `run_full_pipeline()` uses both direct print() and observer calls inconsistently.

**Verification**: CONFIRMED

**Evidence** (sample from pipelines.py):
```python
# Direct prints (no observer):
print("[INFO] Previous run archived successfully", file=sys.stderr)  # line 332
print("[INFO] Journal writer initialized for ML training", file=sys.stderr)  # line 337

# Observer calls:
if observer:
    observer.on_stage_start("FOUNDATION - Sequential Execution", 1)  # line ~614
if observer:
    observer.on_log(idx_msg)  # line ~644
```

**Count**: 37 direct `print()` calls in pipelines.py (34 with file=sys.stderr).

**Impact**: Half the output bypasses the observer pattern entirely.

---

## Discrepancies Found

| Expected | Actual | Impact |
|----------|--------|--------|
| `readthis` cleaned up per pipeline.md | Still created at lines 352-353, 1595-1617 | Zombie code |
| Single output path | 4 paths (direct print, observer, chain print, taint print) | Interleaving |
| Observer pattern complete | Only ~50% of output uses observer | Incomplete migration |

---

| 1. Schema prints at import | CONFIRMED | HIGH |
| 2. readthis still created | CONFIRMED | HIGH |
