|
| 2 |
+
|
| 3 |
+
**Date**: 2024-11-27
|
| 4 |
+
**Reviewer**: AI Agent
|
| 5 |
+
**Scope**: PRs #4, #5, #7 - Logical correctness validation (performance not evaluated)
|

|
| 8 |
+
|

## PR #5: Shared Reward Helper for Metrics
|
| 18 |
+
|
| 19 |
+
**Branch**: `codex/introduce-shared-reward-helper-for-metrics`
|
| 20 |
+
**Verdict**: ✅ **LOGICALLY CORRECT**
|
| 21 |
+
|
| 22 |
+
### What it does
|
| 23 |
+
|
| 24 |
+
Creates `EpisodeRewardHelper` class to centralize reward computation logic previously duplicated between agent and training environment.
|
| 25 |
+
|
| 26 |
+
### Correctness Analysis
|
| 27 |
+
|
| 28 |
+
#### 1. State Tracking ✅
|
| 29 |
+
```python
|
| 30 |
+
_disposed_cases: int = 0
|
| 31 |
+
_hearing_counts: Dict[str, int] = field(default_factory=lambda: defaultdict(int))
|
| 32 |
+
_urgent_latencies: list[float] = field(default_factory=list)
|
| 33 |
+
```
|
| 34 |
+
|
| 35 |
+
**Logic**: Sound. Tracks episode-level metrics incrementally as decisions are made.
|
| 36 |
+
|
| 37 |
+
**Issue**: None. Proper initialization and accumulation.
|
| 38 |
+
|
| 39 |
+
#### 2. Base Reward Computation ✅
|
| 40 |
+
```python
|
| 41 |
+
def _base_outcome_reward(self, case: Case, was_scheduled: bool, hearing_outcome: str) -> float:
|
| 42 |
+
reward = 0.0
|
| 43 |
+
if not was_scheduled:
|
| 44 |
+
return reward
|
| 45 |
+
|
| 46 |
+
reward += 0.5 # Base scheduling reward
|
| 47 |
+
|
| 48 |
+
lower_outcome = hearing_outcome.lower()
|
| 49 |
+
if "disposal" in lower_outcome or "judgment" in lower_outcome or "settlement" in lower_outcome:
|
| 50 |
+
reward += 10.0 # Major positive for disposal
|
| 51 |
+
elif "progress" in lower_outcome and "adjourn" not in lower_outcome:
|
| 52 |
+
reward += 3.0 # Progress without disposal
|
| 53 |
+
elif "adjourn" in lower_outcome:
|
| 54 |
+
reward -= 3.0 # Negative for adjournment
|
| 55 |
+
```
|
| 56 |
+
|
| 57 |
+
**Logic**: Sound. Hierarchical string matching with proper elif chain prevents double-counting.
|
| 58 |
+
|
| 59 |
+
**Issue**: None. "progress" excludes "adjourn" correctly.
|
| 60 |
+
|
| 61 |
+
#### 3. Episode-Level Components ✅
|
| 62 |
+
```python
|
| 63 |
+
disposal_rate = (self._disposed_cases / self.total_cases) if self.total_cases else 0.0
|
| 64 |
+
reward += self.disposal_weight * disposal_rate
|
| 65 |
+
```
|
| 66 |
+
|
| 67 |
+
**Logic**: Sound. Safe division with zero check. Rewards scale with system-level disposal rate.
|
| 68 |
+
|
| 69 |
+
**Issue**: None. Properly guards against division by zero.
|
| 70 |
+
|
| 71 |
+
#### 4. Gap Scoring ✅
|
| 72 |
+
```python
|
| 73 |
+
if previous_gap_days is not None:
|
| 74 |
+
gap_score = max(0.0, 1.0 - (previous_gap_days / self.target_gap_days))
|
| 75 |
+
reward += self.gap_weight * gap_score
|
| 76 |
+
```
|
| 77 |
+
|
| 78 |
+
**Logic**: Sound. Normalized to [0, 1] range, rewards shorter gaps.
|
| 79 |
+
|
| 80 |
+
**Issue**: None. Proper bounds checking with `max(0.0, ...)`.
|
| 81 |
+
|
| 82 |
+
#### 5. Fairness Score ✅
|
| 83 |
+
```python
|
| 84 |
+
def _fairness_score(self) -> float:
|
| 85 |
+
counts: Iterable[int] = self._hearing_counts.values()
|
| 86 |
+
if not counts:
|
| 87 |
+
return 0.0
|
| 88 |
+
|
| 89 |
+
counts_array = np.array(list(counts), dtype=float)
|
| 90 |
+
mean = np.mean(counts_array)
|
| 91 |
+
if mean == 0:
|
| 92 |
+
return 0.0
|
| 93 |
+
|
| 94 |
+
dispersion = np.std(counts_array) / (mean + 1e-6)
|
| 95 |
+
fairness = max(0.0, 1.0 - dispersion)
|
| 96 |
+
return fairness
|
| 97 |
+
```
|
| 98 |
+
|
| 99 |
+
**Logic**: Sound. Coefficient of variation (std/mean) as dispersion metric. Lower dispersion = better fairness.
|
| 100 |
+
|
| 101 |
+
**Issue**: None. Proper zero checks and epsilon stabilization.
|
| 102 |
+
|
| 103 |
+
#### 6. Training Integration ✅
|
| 104 |
+
```python
|
| 105 |
+
# OLD (buggy):
|
| 106 |
+
def _compute_reward(self, case: Case, outcome: str) -> float:
|
| 107 |
+
agent = TabularQAgent() # Creates fresh agent instance!
|
| 108 |
+
return agent.compute_reward(case, was_scheduled=True, hearing_outcome=outcome)
|
| 109 |
+
|
| 110 |
+
# NEW (correct):
|
| 111 |
+
self.reward_helper = EpisodeRewardHelper(total_cases=len(self.cases)) # Reused per episode
|
| 112 |
+
|
| 113 |
+
rewards[case.case_id] = self.reward_helper.compute_case_reward(
|
| 114 |
+
case,
|
| 115 |
+
was_scheduled=True,
|
| 116 |
+
hearing_outcome=outcome,
|
| 117 |
+
current_date=self.current_date,
|
| 118 |
+
previous_gap_days=previous_gap,
|
| 119 |
+
)
|
| 120 |
+
```
|
| 121 |
+
|
| 122 |
+
**Logic**: Sound. Fixes P1 bug - episode helper reused throughout episode instead of fresh agent per case.
|
| 123 |
+
|
| 124 |
+
**Issue**: None. Proper lifecycle management.
|
| 125 |
+
|
| 126 |
+
### Correctness Verdict: ✅ PASS
|
| 127 |
+
|
| 128 |
+
**No logical errors detected.**
|
| 129 |

## PR #4: RL Training Alignment with SchedulingAlgorithm
|
| 133 |
+
|
| 134 |
+
**Branch**: `codex/modify-training-for-schedulingalgorithm-integration`
|
| 135 |
+
**Verdict**: ✅ **LOGICALLY CORRECT**
|
| 136 |
+
|
| 137 |
+
### What it does
|
| 138 |
+
|
| 139 |
+
Integrates production `SchedulingAlgorithm` into RL training environment to close training-production gap.
|
| 140 |
+
|
| 141 |
+
### Correctness Analysis
|
| 142 |
+
|
| 143 |
+
#### 1. Production Components Initialization ✅
|
| 144 |
+
```python
|

self.courtrooms = [

|
| 162 |
+
)
|
| 163 |
+
```
|
| 164 |
+
|
| 165 |
+
**Logic**: Sound. Mirrors production initialization with configurable parameters.
|
| 166 |
+
|
| 167 |
+
**Issue**: None. Proper conditional logic for `min_gap_days`.
|
| 168 |
+
|
| 169 |
+
#### 2. Agent Decisions → Priority Overrides ✅
|
| 170 |
+
```python
|
| 171 |
+
overrides: List[Override] = []
|
| 172 |
+
priority_boost = 1.0
|
| 173 |
+
for case in self.cases:
|
| 174 |
+
if agent_decisions.get(case.case_id) == 1:
|
| 175 |
+
overrides.append(
|
| 176 |
+
Override(
|
| 177 |
+
override_id=f"rl-{case.case_id}-{self.current_date.isoformat()}",
|
| 178 |
+
override_type=OverrideType.PRIORITY,
|
| 179 |
+
case_id=case.case_id,
|
| 180 |
+
judge_id="RL-JUDGE",
|
| 181 |
+
timestamp=self.current_date,
|
| 182 |
+
new_priority=case.get_priority_score() + priority_boost,
|
| 183 |
+
)
|
| 184 |
+
)
|
| 185 |
+
priority_boost += 0.1 # keep relative ordering stable
|
| 186 |
+
```
|
| 187 |
+
|
| 188 |
+
**Logic**: Sound. Converts agent binary decisions (0/1) into priority overrides.
|
| 189 |
+
|
| 190 |
+
**Observation**: Incremental priority boost preserves agent's relative ordering if multiple cases selected.
|
| 191 |
+
|
| 192 |
+
**Issue**: None. Proper override construction.
|
| 193 |
+
|
| 194 |
+
#### 3. Scheduling Algorithm Invocation ✅
|
| 195 |
+
```python
|
| 196 |
+
result = self.algorithm.schedule_day(
|
| 197 |
+
cases=self.cases,
|
| 198 |
+
courtrooms=self.courtrooms,
|
| 199 |
+
current_date=self.current_date,
|
| 200 |
+
overrides=overrides or None,
|
| 201 |
+
preferences=self.preferences,
|
| 202 |
+
)
|
| 203 |
+
|
| 204 |
+
scheduled_cases = [c for cases in result.scheduled_cases.values() for c in cases]
|
| 205 |
+
```
|
| 206 |
+
|
| 207 |
+
**Logic**: Sound. Uses production algorithm with agent's overrides. Flattens scheduled cases across courtrooms.
|
| 208 |
+
|
| 209 |
+
**Issue**: None. Proper dict traversal.
|
| 210 |
+
|
| 211 |
+
#### 4. Capacity Enforcement ✅
|
| 212 |
+
```python
|
| 213 |
+
daily_cap = config.max_daily_allocations or total_capacity
|
| 214 |
+
if not config.cap_daily_allocations:
|
| 215 |
+
daily_cap = len(eligible_cases)
|
| 216 |
+
remaining_slots = min(daily_cap, total_capacity) if config.cap_daily_allocations else daily_cap
|
| 217 |
+
|
| 218 |
+
for case in eligible_cases[:daily_cap]:
|
| 219 |
+
# ... get state and action
|
| 220 |
+
|
| 221 |
+
if config.cap_daily_allocations and action == 1 and remaining_slots <= 0:
|
| 222 |
+
action = 0 # Override agent decision if capacity exhausted
|
| 223 |
+
elif action == 1 and config.cap_daily_allocations:
|
| 224 |
+
remaining_slots = max(0, remaining_slots - 1)
|
| 225 |
+
```
|
| 226 |
+
|
| 227 |
+
**Logic**: Sound. Enforces daily capacity limits. Overrides agent decisions if capacity exhausted.
|
| 228 |
+
|
| 229 |
+
**Issue**: None. Proper decrement and zero check.
|
| 230 |
+
|
| 231 |
+
#### 5. State Space Expansion ✅
|
| 232 |
+
```python
|
| 233 |
+
# OLD: 6-dimensional state
|
| 234 |
+
def to_tuple(self) -> Tuple[int, int, int, int, int, int]:
|
| 235 |
+
return (
|
| 236 |
+
self.stage_encoded,
|
| 237 |
+
min(9, int(self.age_days * 20)),
|
| 238 |
+
min(9, int(self.days_since_last * 20)),
|
| 239 |
+
self.urgency,
|
| 240 |
+
self.ripe,
|
| 241 |
+
min(9, int(self.hearing_count * 20))
|
| 242 |
+
)
|
| 243 |
+
|
| 244 |
+
# NEW: 9-dimensional state
|
| 245 |
+
def to_tuple(self) -> Tuple[int, int, int, int, int, int, int, int, int]:
|
| 246 |
+
return (
|
| 247 |
+
self.stage_encoded,
|
| 248 |
+
min(9, int(self.age_days * 20)),
|
| 249 |
+
min(9, int(self.days_since_last * 20)),
|
| 250 |
+
self.urgency,
|
| 251 |
+
self.ripe,
|
| 252 |
+
min(9, int(self.hearing_count * 20)),
|
| 253 |
+
min(9, int(self.capacity_ratio * 10)), # NEW: remaining capacity
|
| 254 |
+
min(30, self.min_gap_days), # NEW: gap enforcement
|
| 255 |
+
min(9, int(self.preference_score * 10)) # NEW: judge preference alignment
|
| 256 |
+
)
|
| 257 |
+
```
|
| 258 |
+
|
| 259 |
+
**Logic**: Sound. Adds environment context to state representation. Proper discretization and bounds.
|
| 260 |
+
|
| 261 |
+
**Observation**: State space grows from ~10^6 to ~10^9 states (3 orders of magnitude). Q-table may become sparse.
|
| 262 |
+
|
| 263 |
+
**Issue**: None logically. Performance implications exist but correctness is sound.
|
| 264 |
+
|
| 265 |
+
#### 6. Capacity Ratio Helper ✅
|
| 266 |
+
```python
|
| 267 |
+
def capacity_ratio(self, remaining_slots: int) -> float:
|
| 268 |
+
total_capacity = self.rl_config.courtrooms * self.rl_config.daily_capacity_per_courtroom
|
| 269 |
+
return max(0.0, min(1.0, remaining_slots / total_capacity)) if total_capacity else 0.0
|
| 270 |
+
```
|
| 271 |
+
|
| 272 |
+
**Logic**: Sound. Safe division with zero check. Normalized to [0, 1].
|
| 273 |
+
|
| 274 |
+
**Issue**: None.
|
| 275 |
+
|
| 276 |
+
#### 7. Preference Score Helper ✅
|
| 277 |
+
```python
|
| 278 |
+
def preference_score(self, case: Case) -> float:
|
| 279 |
+
if not self.preferences:
|
| 280 |
+
return 0.0
|
| 281 |
+
|
| 282 |
+
day_name = self.current_date.strftime("%A")
|
| 283 |
+
preferred_types = self.preferences.case_type_preferences.get(day_name, [])
|
| 284 |
+
return 1.0 if case.case_type in preferred_types else 0.0
|
| 285 |
+
```
|
| 286 |
+
|
| 287 |
+
**Logic**: Sound. Binary preference signal (1.0 if aligned, 0.0 otherwise).
|
| 288 |
+
|
| 289 |
+
**Issue**: None.
|
| 290 |
+
|
| 291 |
+
### Correctness Verdict: ✅ PASS
|
| 292 |
+
|
| 293 |
+
**No logical errors detected.** State space expansion is intentional and correctly implemented.
|
| 294 |

## PR #7: Output Manager Metadata Tracking
|
| 298 |
+
|
| 299 |
+
**Branch**: `codex/extend-output-manager-for-eda-recording`
|
| 300 |
+
**Verdict**: ✅ **LOGICALLY CORRECT**
|
| 301 |
+
|
| 302 |
+
### What it does
|
| 303 |
+
|
| 304 |
+
Adds metadata recording to `OutputManager` for EDA versioning, training KPIs, evaluation stats, and simulation metrics.
|
| 305 |
+
|
| 306 |
+
### Correctness Analysis
|
| 307 |
+
|
| 308 |
+
#### 1. Run Record Initialization ✅
|
| 309 |
+
```python
|
| 310 |
+
def create_structure(self):
|
| 311 |
+
# ... create directories
|
| 312 |
+
|
| 313 |
+
if not self.run_record_file.exists():
|
| 314 |
+
self._update_run_record("run", {
|
| 315 |
+
"run_id": self.run_id,
|
| 316 |
+
"created_at": self.created_at,
|
| 317 |
+
"base_dir": str(self.run_dir),
|
| 318 |
+
})
|
| 319 |
+
```
|
| 320 |
+
|
| 321 |
+
**Logic**: Sound. Initializes run record on first directory creation.
|
| 322 |
+
|
| 323 |
+
**Issue**: None. Idempotent check with `exists()`.
|
| 324 |
+
|
| 325 |
+
#### 2. Run Record Update Helper ✅
|
| 326 |
+
```python
|
| 327 |
+
def _update_run_record(self, section: str, payload: Dict[str, Any]):
|
| 328 |
+
record = self._load_run_record()
|
| 329 |
+
record.setdefault("sections", {})
|
| 330 |
+
record["sections"][section] = payload
|
| 331 |
+
record["updated_at"] = datetime.now().isoformat()
|
| 332 |
+
|
| 333 |
+
with open(self.run_record_file, "w", encoding="utf-8") as f:
|
| 334 |
+
json.dump(record, f, indent=2, default=str)
|
| 335 |
+
```
|
| 336 |
+
|
| 337 |
+
**Logic**: Sound. Atomic section updates with timestamp tracking. UTF-8 encoding for Windows compatibility.
|
| 338 |
+
|
| 339 |
+
**Issue**: None. Proper dictionary mutation pattern.
|
| 340 |
+
|
| 341 |
+
#### 3. EDA Metadata Recording ✅
|
| 342 |
+
```python
|
| 343 |
+
def record_eda_metadata(self, version: str, used_cached: bool, params_path: Path, figures_path: Path):
|
| 344 |
+
payload = {
|
| 345 |
+
"version": version,
|
| 346 |
+
"timestamp": datetime.now().isoformat(),
|
| 347 |
+
"used_cached": used_cached,
|
| 348 |
+
"params_path": str(params_path),
|
| 349 |
+
"figures_path": str(figures_path),
|
| 350 |
+
}
|
| 351 |
+
|
| 352 |
+
self._update_run_record("eda", payload)
|
| 353 |
+
```
|
| 354 |
+
|
| 355 |
+
**Logic**: Sound. Tracks EDA version and cache usage for reproducibility.
|
| 356 |
+
|
| 357 |
+
**Issue**: None. Clean separation of concerns.
|
| 358 |
+
|
| 359 |
+
#### 4. Training Stats Persistence ✅
|
| 360 |
+
```python
|
| 361 |
+
def save_training_stats(self, training_stats: Dict[str, Any]):
|
| 362 |
+
self.training_dir.mkdir(parents=True, exist_ok=True)
|
| 363 |
+
with open(self.training_stats_file, "w", encoding="utf-8") as f:
|
| 364 |
+
json.dump(training_stats, f, indent=2, default=str)
|
| 365 |
+
```
|
| 366 |
+
|
| 367 |
+
**Logic**: Sound. Saves raw training statistics to dedicated file.
|
| 368 |
+
|
| 369 |
+
**Issue**: None. Proper directory creation.
|
| 370 |
+
|
| 371 |
+
#### 5. Evaluation Stats Persistence ✅
|
| 372 |
+
```python
|
| 373 |
+
def save_evaluation_stats(self, evaluation_stats: Dict[str, Any]):
|
| 374 |
+
eval_path = self.training_dir / "evaluation.json"
|
| 375 |
+
with open(eval_path, "w", encoding="utf-8") as f:
|
| 376 |
+
json.dump(evaluation_stats, f, indent=2, default=str)
|
| 377 |
+
|
| 378 |
+
self._update_run_record("evaluation", {
|
| 379 |
+
"path": str(eval_path),
|
| 380 |
+
"timestamp": datetime.now().isoformat(),
|
| 381 |
+
})
|
| 382 |
+
```
|
| 383 |
+
|
| 384 |
+
**Logic**: Sound. Persists evaluation metrics and updates run record.
|
| 385 |
+
|
| 386 |
+
**Issue**: None. Consistent pattern.
|
| 387 |
+
|
| 388 |
+
#### 6. Simulation KPI Recording ✅
|
| 389 |
+
```python
|
| 390 |
+
def record_simulation_kpis(self, policy: str, kpis: Dict[str, Any]):
|
| 391 |
+
policy_dir = self.get_policy_dir(policy)
|
| 392 |
+
metrics_path = policy_dir / "metrics.json"
|
| 393 |
+
with open(metrics_path, "w", encoding="utf-8") as f:
|
| 394 |
+
json.dump(kpis, f, indent=2, default=str)
|
| 395 |
+
|
| 396 |
+
record = self._load_run_record()
|
| 397 |
+
simulation_section = record.get("simulation", {})
|
| 398 |
+
simulation_section[policy] = kpis
|
| 399 |
+
record["simulation"] = simulation_section
|
| 400 |
+
record["updated_at"] = datetime.now().isoformat()
|
| 401 |
+
|
| 402 |
+
with open(self.run_record_file, "w", encoding="utf-8") as f:
|
| 403 |
+
json.dump(record, f, indent=2, default=str)
|
| 404 |
+
```
|
| 405 |
+
|
| 406 |
+
**Logic**: Sound. Per-policy metrics storage with consolidated run record tracking.
|
| 407 |
+
|
| 408 |
+
**Issue**: None. Proper nested dictionary updates.
|
| 409 |
+
|
| 410 |
+
#### 7. Integration in Pipeline ✅
|
| 411 |
+
|
| 412 |
+
**EDA Recording**:
|
| 413 |
+
```python
|
| 414 |
+
self.output.record_eda_metadata(
|
| 415 |
+
version=eda_config.VERSION,
|
| 416 |
+
used_cached=True,
|
| 417 |
+
params_path=self.output.eda_params,
|
| 418 |
+
figures_path=self.output.eda_figures,
|
| 419 |
+
)
|
| 420 |
+
```
|
| 421 |
+
|
| 422 |
+
**Training Recording**:
|
| 423 |
+
```python
|
| 424 |
+
self.output.save_training_stats(training_stats)
|
| 425 |
+
self.output.save_evaluation_stats(evaluation_stats)
|
| 426 |
+
self.output.record_training_summary(training_summary, evaluation_stats)
|
| 427 |
+
```
|
| 428 |
+
|
| 429 |
+
**Simulation Recording**:
|
| 430 |
+
```python
|
| 431 |
+
kpis = {
|
| 432 |
+
"policy": policy,
|
| 433 |
+
"disposals": result.disposals,
|
| 434 |
+
"disposal_rate": result.disposals / len(policy_cases),
|
| 435 |
+
# ... other metrics
|
| 436 |
+
}
|
| 437 |
+
self.output.record_simulation_kpis(policy, kpis)
|
| 438 |
+
```
|
| 439 |
+
|
| 440 |
+
**Logic**: Sound. Proper integration at each pipeline stage. Captures metadata at point of generation.
|
| 441 |
+
|
| 442 |
+
**Issue**: None. Clean separation of concerns.
|
| 443 |
+
|
| 444 |
+
#### 8. Error Handling ✅
|
| 445 |
+
```python
|
| 446 |
+
try:
|
| 447 |
+
evaluation_stats = evaluate_agent(...)
|
| 448 |
+
self.output.save_evaluation_stats(evaluation_stats)
|
| 449 |
+
except Exception as eval_err:
|
| 450 |
+
console.print(f" [yellow]WARNING[/yellow] Evaluation skipped: {eval_err}")
|
| 451 |
+
```
|
| 452 |
+
|
| 453 |
+
**Logic**: Sound. Graceful degradation if evaluation fails. Warning instead of crash.
|
| 454 |
+
|
| 455 |
+
**Issue**: None. Proper exception handling.
|
| 456 |
+
|
| 457 |
+
### Correctness Verdict: ✅ PASS
|
| 458 |
+
|
| 459 |
+
**No logical errors detected.** All metadata recording is additive and safe.
|
| 460 |
+

| 464 |
+
|
| 465 |
+
### PR #4 + PR #5 Interaction ✅
|
| 466 |
+
|
| 467 |
+
**Scenario**: Both modify `rl/training.py`
|
| 468 |
+
|
| 469 |
+
**Conflict**: PR #4 adds capacity/preference context to state extraction. PR #5 replaces reward computation with helper.
|
| 470 |
+
|
| 471 |
+
**Resolution**: Compatible. Different concerns - state representation vs reward computation.
|
| 472 |
+
|
| 473 |
+
**Merge Strategy**: Either order works. No logical dependency.
|
| 474 |
+
|
| 475 |
+
### PR #7 Integration ✅
|
| 476 |
+
|
| 477 |
+
**Scenario**: PR #7 adds metadata tracking to `OutputManager` and `court_scheduler_rl.py`
|
| 478 |
+
|
| 479 |
+
**Conflict**: None. Purely additive changes.
|
| 480 |
+
|
| 481 |
+
**Resolution**: Independent of PR #4 and #5. Can merge in any order.
|
| 482 |

## Final Recommendation
|
| 486 |
+
|
| 487 |
+
### All Three PRs: ✅ APPROVE
|
| 488 |
+
|
| 489 |
+
**Logical Correctness**: All three PRs are logically sound with no errors, broken invariants, or dangerous assumptions.
|
| 490 |
+
|
| 491 |
+
**Merge Order** (any order works, but suggested sequence):
|
| 492 |
+
|
| 493 |
+
1. **PR #5** (Shared reward logic) - Low complexity, fixes P1 bug
|
| 494 |
+
2. **PR #4** (RL training alignment) - High complexity, but logically correct
|
| 495 |
+
3. **PR #7** (Output metadata) - Pure additive, no conflicts
|
| 496 |
+
|
| 497 |
+
**No blockers for merge based on logical correctness alone.**

-
|
| 34 |
-
### ✅ PR #2: Refine override validation and cleanup
|
| 35 |
-
**Branch**: `codex/refactor-override-handling-in-algorithm.py`
|
| 36 |
-
**Status**: HIGHLY RECOMMENDED
|
| 37 |
-
**Impact**: Fixes P0 critical bug (override state pollution)
|
| 38 |
-
|
| 39 |
-
**What it does**:
|
| 40 |
-
1. Validates overrides into separate `validated_overrides` list
|
| 41 |
-
2. Preserves original override list (no in-place mutation)
|
| 42 |
-
3. Adds `override_rejections` to SchedulingResult for auditability
|
| 43 |
-
4. Implements `_clear_temporary_case_flags()` to clean `_priority_override`
|
| 44 |
-
|
| 45 |
-
**Code quality**:
|
| 46 |
-
```python
|
| 47 |
-
# OLD (buggy):
|
| 48 |
-
overrides = [o for o in overrides if o != override] # Mutates input!
|
| 49 |
-
|
| 50 |
-
# NEW (correct):
|
| 51 |
-
validated_overrides.append(override) # Separate list
|
| 52 |
-
override_rejections.append({...}) # Structured tracking
|
| 53 |
-
```
|
| 54 |
-
|
| 55 |
-
**Assessment**:
|
| 56 |
-
- ✅ Solves: Override state leakage (P0 bug)
|
| 57 |
-
- ✅ Preserves: Original override list for auditing
|
| 58 |
-

| 59 |
-
- ✅ Cleans: Temporary flags after scheduling
|
| 60 |
-
- ⚠️ Missing: Tests (Codex didn't run tests)
|
| 61 |
-
|
| 62 |
-
**Risks**:
|
| 63 |
-
- LOW: Logic is sound, follows our enhancement plan exactly
|
| 64 |
-
- Need to verify `_clear_temporary_case_flags()` is called after every scheduling
|
| 65 |
-
|
| 66 |
-
**Recommendation**: **MERGE** with integration test validation
|
| 67 |
-
|
| 68 |

### ✅ PR #3: Add unknown ripeness classification
|
| 71 |
-
**Branch**: `codex/update-ripeness.py-for-unknown-state-handling`
|
| 72 |
-
**Status**: HIGHLY RECOMMENDED
|
| 73 |
-
**Impact**: Fixes P0 critical bug (ripeness defaults to RIPE)
|
| 74 |
-
|
| 75 |
-
**What it does**:
|
| 76 |
-
1. Adds `UNKNOWN` to RipenessStatus enum
|
| 77 |
-
2. Requires positive evidence (service/compliance/age thresholds)
|
| 78 |
-
3. Defaults to UNKNOWN instead of RIPE when ambiguous
|
| 79 |
-
4. Routes UNKNOWN cases to manual triage
|
| 80 |
-
|
| 81 |
-
**Assessment**:
|
| 82 |
-
- ✅ Solves: Optimistic RIPE default (P0 bug)
|
| 83 |
-
- ✅ Safe: UNKNOWN cases filtered from scheduling
|
| 84 |
-
- ✅ Conservative: Requires affirmative evidence
|
| 85 |
-
- ⚠️ Missing: Tests
|
| 86 |
-
|
| 87 |
-
**Risks**:
|
| 88 |
-
- MEDIUM: May filter too many cases initially
|
| 89 |
-
- Need to tune thresholds based on false positive rate
|
| 90 |
-
- Should track UNKNOWN distribution in metrics
|
| 91 |
-
|
| 92 |
-
**Recommendation**: **MERGE** with metric tracking
|
| 93 |
-
|
| 94 |

-
**Status**: NEEDS CAREFUL REVIEW
|
| 99 |
-
**Impact**: Refactors RL training environment (high complexity)
|
| 100 |
-
|
| 101 |
-
**What it does**:
|
| 102 |
-
1. Integrates SchedulingAlgorithm into training environment
|
| 103 |
-
2. Adds courtroom allocator and judge preferences to training
|
| 104 |
-
3. Enriches agent state with capacity/gap/preference context
|
| 105 |
-
4. Caps daily scheduling decisions to production limits
|
| 106 |
-
|
| 107 |
-
**Assessment**:
|
| 108 |
-
- ✅ Addresses: Training-production gap (P1 issue)
|
| 109 |
-
- ✅ Aligned: Uses real SchedulingAlgorithm in training
|
| 110 |
-
- ⚠️ Complexity: Major refactor of training loop
|
| 111 |
-
- ⚠️ State space: Expanding from 6D may hurt learning
|
| 112 |
-
- ⚠️ Performance: SchedulingAlgorithm slower than simplified env
|
| 113 |
-
|
| 114 |
-
**Risks**:
|
| 115 |
-
- HIGH: Could break existing trained agents
|
| 116 |
-
- HIGH: State space explosion may prevent convergence
|
| 117 |
-
- MEDIUM: Training time may increase significantly
|
| 118 |
-
|
| 119 |
-
**Recommendation**: **MERGE AFTER**:
|
| 120 |
-
1. Benchmark training time (old vs new)
|
| 121 |
-
2. Verify agent still learns (disposal rate improves)
|
| 122 |
-
3. Compare final policy performance
|
| 123 |
-
4. Consider keeping old training as fallback
|
| 124 |
-
|

| 129 |
-
**Status**: NEEDS REVIEW
|
| 130 |
-
**Impact**: Refactors reward computation
|
| 131 |
-
|
| 132 |
-
**What it does**:
|
| 133 |
-
1. Creates `EpisodeRewardHelper` class
|
| 134 |
-
2. Shapes rewards using episode-level metrics (disposal rate, fairness, gaps)
|
| 135 |
-
3. Removes agent re-instantiation in environment
|
| 136 |
-
4. Tracks hearing gaps for better reward signals
|
| 137 |
-
|
| 138 |
-
**Assessment**:
|
| 139 |
-
- ✅ Addresses: Reward computation inconsistency (P1 issue)
|
| 140 |
-
- ✅ Shared: Same logic in training and environment
|
| 141 |
-
- ⚠️ Episode-level: May dilute per-step learning signal
|
| 142 |
-
- ⚠️ Complexity: More sophisticated reward shaping
|
| 143 |
-
|
| 144 |
-
**Risks**:
|
| 145 |
-
- MEDIUM: Different reward structure may require retraining
|
| 146 |
-
- LOW: Logic appears sound
|
| 147 |
-
|
| 148 |
-
**Recommendation**: **MERGE AFTER**:
|
| 149 |
-
1. Compare reward curves (old vs new)
|
| 150 |
-
2. Verify improved convergence
|
| 151 |
-
3. Document reward weights

| 157 |
-
**Status**: RECOMMENDED
|
| 158 |
-
**Impact**: Fixes P1 issue (missing parameter fallback)
|
| 159 |
-
|
| 160 |
-
**What it does**:
|
| 161 |
-
1. Bundles baseline parameters in `scheduler/data/defaults/`
|
| 162 |
-
2. Auto-runs EDA pipeline or falls back to bundled defaults
|
| 163 |
-
3. Adds `--use-defaults` and `--regenerate` CLI flags
|
| 164 |
-
4. Clearer error messages
|
| 165 |
-
|
| 166 |
-
**Assessment**:
|
| 167 |
-
- ✅ Solves: Fresh environment blocking (P1 issue)
|
| 168 |
-
- ✅ UX: Clear error messages and automatic fallback
|
| 169 |
-
- ✅ Safe: Bundled defaults allow immediate use
|
| 170 |
-
- ⚠️ Missing: Actual default parameter files
|
| 171 |
-
|
| 172 |
-
**Risks**:
|
| 173 |
-
- LOW: Need to verify bundled defaults are reasonable
|
| 174 |
-
- Need to test auto-EDA trigger
|
| 175 |
-
|
| 176 |
-
**Recommendation**: **MERGE** after verifying:
|
| 177 |
-
1. Bundled defaults exist and are reasonable
|
| 178 |
-
2. Auto-EDA trigger works correctly
|
| 179 |
-
3. Error messages are helpful
|
| 180 |

**Status**: NICE TO HAVE
|
| 186 |
-
**Impact**: Adds metadata tracking (low priority)
|
| 187 |
-
|
| 188 |
-
**What it does**:
|
| 189 |
-
1. Captures EDA version and timestamps in OutputManager
|
| 190 |
-
2. Persists RL training/evaluation/simulation KPIs
|
| 191 |
-
3. Initializes structured run metadata for dashboard ingestion
|
| 192 |
-
|
| 193 |
-
**Assessment**:
|
| 194 |

|
| 195 |
-
- ✅ Safe: Additive changes only
|
| 196 |
-
- ⚠️ Low priority: Not critical for hackathon
|
| 197 |
-
|
| 198 |
-
**Risks**:
|
| 199 |
-
- NONE: Purely additive
|
| 200 |
-
|
| 201 |
-
**Recommendation**: **MERGE LAST** (after #1-6 validated)
|
| 202 |

# Output Directory Refactoring - Implementation Status
|
| 2 |
-
|
| 3 |
-
## Completed
|
| 4 |
-
|
| 5 |
-
### 1. Created `OutputManager` class
|
| 6 |
-
- **File**: `scheduler/utils/output_manager.py`
|
| 7 |
-
- **Features**:
|
| 8 |
-
- Single run directory with timestamp-based ID
|
| 9 |
-
- Clean hierarchy: `eda/` `training/` `simulation/` `reports/`
|
| 10 |
-
- Property-based access to all output paths
|
| 11 |
-
- Config saved to run root for reproducibility
|
| 12 |
-
|
| 13 |
-
### 2. Integrated into Pipeline
|
| 14 |
-
- **File**: `court_scheduler_rl.py`
|
| 15 |
-
- **Changes**:
|
| 16 |
-
- `PipelineConfig` no longer has `output_dir` field
|
| 17 |
-
- `InteractivePipeline` uses `OutputManager` instance
|
| 18 |
-
- All `self.output_dir` references replaced with `self.output.{property}`
|
| 19 |
-
- Pipeline compiles successfully
|
| 20 |
-
|
| 21 |
-
## Completed Tasks
|
| 22 |
-
|
| 23 |
-
### 1. Remove Duplicate Model Saving (DONE)
|
| 24 |
-
- Removed duplicate model save in court_scheduler_rl.py
|
| 25 |
-
- Implemented `OutputManager.create_model_symlink()` method
|
| 26 |
-
- Model saved once to `outputs/runs/{run_id}/training/agent.pkl`
|
| 27 |
-
- Symlink created at `models/latest.pkl`
|
| 28 |
-
|
| 29 |
-
### 2. Update EDA Output Paths (DONE)
|
| 30 |
-
- Modified `src/eda_config.py` with:
|
| 31 |
-
- `set_output_paths()` function to configure from OutputManager
|
| 32 |
-
- Private getter functions (`_get_run_dir()`, `_get_params_dir()`, etc.)
|
| 33 |
-
- Fallback to legacy paths when running standalone
|
| 34 |
-
- Updated all EDA modules (eda_load_clean.py, eda_exploration.py, eda_parameters.py)
|
| 35 |
-
- Pipeline calls `set_output_paths()` before running EDA steps
|
| 36 |
-
- EDA outputs now write to `outputs/runs/{run_id}/eda/`
|
| 37 |
-
|
| 38 |
-
### 3. Fix Import Errors (DONE)
|
| 39 |
-
- Fixed syntax errors in EDA imports (removed parentheses from function names)
|
| 40 |
-
- All modules compile without errors
|
| 41 |
-
|
| 42 |
-
### 4. Test End-to-End (DONE)
|
| 43 |
-
```bash
|
| 44 |
-
uv run python court_scheduler_rl.py quick
|
| 45 |
-
```
|
| 46 |
-
|
| 47 |
-
**Status**: SUCCESS (Exit code: 0)
|
| 48 |
-
- All outputs in `outputs/runs/run_20251126_055943/`
|
| 49 |
-
- No scattered files
|
| 50 |
-
- Models symlinked correctly at `models/latest.pkl`
|
| 51 |
-
- Pipeline runs without errors
|
| 52 |
-
- Clean directory structure verified with `tree` command
|
| 53 |
-
|
| 54 |
-
## New Directory Structure

## Benefits Achieved
|
| 82 |
-
|
| 83 |
-
1. **Single source of truth**: All run artifacts in one directory
|
| 84 |
-
2. **Reproducibility**: Config saved with outputs
|
| 85 |
-
3. **No duplication**: Files written once, not copied
|
| 86 |
-
4. **Clear hierarchy**: Logical organization by pipeline phase
|
| 87 |
-
5. **Easy cleanup**: Delete entire run directory
|
| 88 |
-
6. **Version control**: Run IDs sortable by timestamp
