## ✅ P0 Testing Results (100% COMPLETE)

### P0.1: Configuration System ✅

**Task:** Implement .env-based configuration (no system environment variables)

**Actions Taken:**
1. Added `python-dotenv>=1.0.0` to `pyproject.toml`
2. Created `compalgo/config.py` module with `AlgoConfig` class
3. Created `.env.example` template with safe placeholders
4. Updated `.gitignore` to exclude `.env` and `examples/output/*.json`
5. Modified SDK client to support `.env` loading via `from_env()` method
6. Updated CLI commands (`anchor`, `verify`) to load from `.env`

**Files Modified:**
- ✅ `pyproject.toml` - Added python-dotenv dependency
- ✅ `compalgo/config.py` - **NEW FILE** - Configuration management
- ✅ `.env.example` - **NEW FILE** - Safe template
- ✅ `compalgo/client/__init__.py` - Added `from_env()` classmethod
- ✅ `compalgo/cli/main.py` - Updated anchor/verify commands

**Test Evidence:**
```bash
# .env configuration successfully loads
✅ Config loaded: AlgoConfig(network=testnet, algod_url=https://testnet-api.algonode.cloud, 
   indexer_url=https://testnet-idx.algonode.cloud, mnemonic=***SET***)

## 🐛 Bugs Found & Fixed

### Bug #1: Mnemonic Length Validation Error (CRITICAL)

**Discovered:** December 2, 2025, 12:14 AM

**Error Message:**
```
❌ Anchoring failed: mnemonic length must be 25
```

**Root Cause:**
- User's Pera Wallet only displayed 24 words on mobile
- Possibly incomplete recovery phrase backup

**Investigation:**
- Validated Algorand requires exactly 25 words
- Checked `.env` file format
- Verified mnemonic parsing in `config.py`

**Resolution:**
- Generated new Algorand wallet with proper 25-word mnemonic
- Updated `.env` with new mnemonic:
  ```
  ALGO_MNEMONIC=slogan special lemon any acid mercy length boss concert label orange october witness danger among silly member review credit scrub inner rocket tissue about blade
  ```
- Obtained TestNet ALGO from faucet
- Verified wallet configuration

**Test After Fix:**
```
✅ Config loaded: AlgoConfig(network=testnet, algod_url=https://testnet-api.algonode.cloud, 
   indexer_url=https://testnet-idx.algonode.cloud, mnemonic=***SET***)
✅ Anchored successfully!
```

**Status:** ✅ RESOLVED

**Impact:** Critical - Blocked all anchoring operations  
**Time to Resolve:** ~15 minutes

---

### Bug #2: Verdict File Not Created on Check Failure (HIGH)

**Discovered:** December 2, 2025, 12:38 AM

**Error Message:**
```
Error: Invalid value for '--verdict': Path 'my_verdict.json' does not exist.
```

**Root Cause:**
- CLI `check` command exited with error before creating verdict file when contract failed compliance
- Logic error: `sys.exit(1)` called before verdict file generation

**Problem Code Location:**
`compalgo/cli/main.py` lines 90-120

**Original Flow (BUGGY):**
```python
# Print violations
...
if failed:
    console.print(f"[red]Failed {failed}/{total_files} file(s)[/red]")
    sys.exit(1)  # ❌ EXIT HERE - verdict never created

# Verdict generation (never reached on failure)
if verdict_out:
    verdict = build_verdict(...)
    _save_text(verdict_out, ...)
```

**Fix Applied:**
Moved verdict generation BEFORE the exit call:

```python
# Print violations
...

# Generate verdict FIRST (even on failure)
if verdict_out:
    verdict = build_verdict(...)
    _save_text(verdict_out, ...)
    console.print(f"[green]Verdict written:[/green] {verdict_out}")

# THEN exit with appropriate code
if failed:
    console.print(f"[red]Failed {failed}/{total_files} file(s)[/red]")
    sys.exit(1)
```

**Test After Fix:**
```bash
compalgo check examples/vulnerable_escrow.py --verdict-out my_verdict.json

Result:
Verdict written: my_verdict.json  ✅
Failed 1/1 file(s)                ✅ (Expected - contract is vulnerable)
```

**Status:** ✅ RESOLVED

**Impact:** High - Prevented CLI workflow for failing contracts  
**Time to Resolve:** ~5 minutes

**Why This Fix Matters:**
- Failing verdicts are MORE important to anchor than passing ones
- You need proof that a contract was audited and found non-compliant
- Now both passing and failing verdicts are properly captured

     - TV-003 through TV-010 (verification edge cases)
     - TE-001 through TE-010 (E2E scenarios)

### Documentation
4. **Update Main README** 📋 LOW PRIORITY
   - Highlight P1 features already implemented
   - Update installation instructions
   - Add badges (tests, coverage, PyPI)

---

## 🎯 Recommendations

### Immediate Actions (This Week)
1. ✅ **Push to GitHub** - Test CI workflows
