The agent acts, receives reward, and the world returns to a known starting configuration. This is computationally convenient and theoretically clean. It is also completely wrong as a model of the real world. In the real world, some actions cannot be undone. A message sent to an external party cannot be recalled. An employee terminated during a crisis cannot be reinstated. A public commitment made under a deadline cannot be retracted. These are not edge cases — they are the defining characteristic of consequential decisions. Current LLM agents have received zero training signal for this distinction. They have never experienced an action that permanently changed the world. Every world they have trained in has forgiven every mistake by resetting. The result is agents that treat all actions as equally recoverable, that optimize for immediate reward without modeling downstream constraint propagation, and that fail in deployment when they discover the world does not reset. PERMANENCE is the training environment that fixes this. ## 1.2 The Core Training Objective PERMANENCE trains one specific capability: accurate prediction of action reversibility before acting, combined with appropriate deliberation proportional to irreversibility level. This is not caution training. An agent trained on PERMANENCE will take bold irreversible actions when it has correctly classified them as irreversible and determined they are the right action. Task 4 (The Crisis) requires the agent to issue a public statement — a high-irreversibility action — or fail the task. The reward function penalizes over-caution and under-caution equally. The capability being trained is accuracy of world-modeling, not risk aversion. ## 1.3 Architectural Novelty Three properties have no precedent in existing OpenEnv environments: **Property 1 — Within-episode persistent world state.** Actions in step 1 constrain what is possible in step 15. The world remembers within an episode. **Property 2 — Computed reversibility.** R-level is computed at execution time as a function of current world state. The same action type can have different R-level in different contexts. **Property 3 — First-class prediction interface.** The environment evaluates what the agent predicted about an action before taking it. Prediction accuracy is a primary reward component. --- # PART 2: SYSTEM ARCHITECTURE ## 2.1 Architectural Principles These principles govern every implementation decision. When in doubt, return here. **Principle 1 — Determinism above all.** Every computation in the reward function must be fully deterministic. No LLM calls in reward computation. No stochastic elements in world state transitions. **Principle 2 — R-level is a function, never a constant.** Computed from `r_level_fn(world_state, action_parameters)` at execution time. Never stored as a static integer. **Principle 3 — Prediction extraction is best-effort, never blocking.** Parse failure means zero prediction score for that step. The episode continues. No exception is ever raised because the agent formatted its output incorrectly. **Principle 4 — Curriculum is enforced by the environment.** The training script calls `env.reset()` and `env.step()`. The environment selects tasks internally based on episode count. **Principle 5 — World state persists within episodes, resets between.** `reset()` creates a fresh world state. The world state from episode N is never accessible in episode N+1. **Principle 6 — Every parameter access uses `.get()` with a default.** No precondition lambda, consequence function, or reward computation ever uses `dict["key"]` directly. Always `dict.get("key", default)`. No exceptions to this rule. **Principle 7 — Observation length is bounded.** The observation formatter enforces a maximum token budget. History is summarized to last N items only. The task instruction always appears last, closest to the model's attention peak. **Principle 8 — Invalid action IDs terminate the step with a penalty.** Unknown action IDs return -0.1 reward and consume one step count. The episode terminates at max_steps regardless of what actions are taken. ## 2.2 Component Map ``` PermanenceEnv (env.py) │ ├── TaskManager (task_manager.py) │ ├── CurriculumScheduler │ └── TaskBank [5 tasks] │ └── TaskTemplate │ ├── ScenarioGenerator (parameterized) │ └── SuccessCriteria │ ├── WorldEngine (world_engine.py) │ ├── WorldState (dataclass) │ │ ├── EmployeeGraph │ │ ├── ProjectRegister │ │ ├── ExternalRelationships │ │ ├── ActionHistory (bounded, max 30 entries) │ │ ├── LockedActions │ │ └── CriticalOptions │ ├── ActionRegistry (action_registry.py) │ │ └── ActionDefinition [19 actions] │ │ ├── required_parameters: List[str] │ │ ├── optional_parameters: Dict[str, Any] │ │ ├── Preconditions (all using .get()) │ │ ├── Consequences (typed MutationType enum) │ │ └── r_level_fn: Callable[[WorldState, Dict], int] │ └── ConsequenceEngine (consequence_engine.py) │ └── typed mutation handlers, never raises exceptions │ ├── AgentInterface (agent_interface.py) │ ├── ObservationFormatter (bounded, max 1800 tokens) │ └── ActionParser │ ├── re.DOTALL on all patterns │ ├── markdown block stripping │ └── _safe_parse_float() for confidence │ ├── RewardEngine (reward_engine.py) │ ├── TaskCompletionEvaluator │ ├── PredictionAccuracyEvaluator (0.0 for missing confidence) │ ├── OptionPreservationEvaluator │ └── CatastrophePenaltyEvaluator (capped at 4.0) │ └── EpisodeTracker (episode_tracker.py) ├── maintains step count (enforced max_steps) ├── records PredictionRecords per step └── produces EpisodeResult at termination ``` ## 2.3 Data Flow Through One Episode ``` 1. env.reset() → CurriculumScheduler selects task by episode count → ScenarioGenerator samples parameters (seeded) → WorldState initialized fresh from scenario parameters → EpisodeTracker resets → ObservationFormatter renders bounded initial observation → returns (observation_dict, info_dict) 2.

All fail to parse. All receive -0.1 reward. Group variance ≈ 0. GRPO advantages all ≈ 0. No gradient flows. Training never starts. **Three-mechanism fix:** ### Mechanism 1 — Warm-up SFT (20 hand-crafted correct traces) Before any RL, run 2 epochs of supervised fine-tuning on 20 hand-crafted episode traces. These traces demonstrate correct output format and example reversibility reasoning. After warm-up, the model reliably produces parseable output, providing reward variance across the GRPO group. ```python WARMUP_TRACES_PATH = "training/warmup_traces.jsonl" # 20 traces: 4 per task, covering correct behavior on easy examples # Format: {"prompt": "...", "completion": "...\n\n"} ``` ### Mechanism 2 — Format reward during early training (episodes 0–300) A small auxiliary reward (weight 0.05, added outside main reward function) for producing correctly formatted output. Provides gradient even when all group responses fail the task. Removed after episode 300 once format is stable. ```python FORMAT_REWARD_WEIGHT = 0.05 FORMAT_REWARD_CUTOFF_EPISODE = 300 def compute_format_reward(agent_output: str) -> float: """0.1 if both and tags present. Else 0.0.""" has_action = bool(ACTION_TAG_PATTERN.search(agent_output)) has_rev = bool(REVERSIBILITY_TAG_PATTERN.search(agent_output)) return 0.1 if (has_action and has_rev) else 0.0 ``` ### Mechanism 3 — Zero-variance group skip If all GROUP_SIZE responses have identical reward (std < 1e-4), skip the weight update for that batch. Move to next episode. Never update on zero-variance groups. ```python ZERO_VARIANCE_THRESHOLD = 1e-4 def run_grpo_group( model, observation: str, env_copy, episode: int, config: TrainingConfig ) -> Optional['GroupTrainingData']: """ Returns None if group has zero variance → caller skips weight update. """ responses = [ model.generate(format_prompt(observation), temperature=0.8, max_new_tokens=512) for _ in range(config.group_size) ] rewards = [] for response in responses: _, step_reward, _, _, info = env_copy.step(response) task_reward = ( info["reward_breakdown"].total if "reward_breakdown" in info else step_reward ) if episode < FORMAT_REWARD_CUTOFF_EPISODE: task_reward += FORMAT_REWARD_WEIGHT * compute_format_reward(response) rewards.append(task_reward) reward_std = float(np.std(rewards)) if reward_std < ZERO_VARIANCE_THRESHOLD: return None # Skip update mean_reward = float(np.mean(rewards)) advantages = [(r - mean_reward) / (reward_std + 1e-8) for r in rewards] return GroupTrainingData(responses=responses, rewards=rewards, advantages=advantages) ``` ## 8.2 Training Configuration ```python @dataclass class TrainingConfig: model_name: str = "meta-llama/Llama-3.2-3B-Instruct" total_episodes: int = 1500 group_size: int = 8 learning_rate: float = 2e-5 lr_schedule: str = "cosine" kl_coefficient: float = 0.02 gradient_clip: float = 1.0 lora_r: int = 16 lora_alpha: int = 16 load_in_4bit: bool = True eval_episodes: int = 50 eval_seed_offset: int = 10000 output_dir: str = "./permanence_output" checkpoint_frequency: int = 500 warmup_sft_epochs: int = 2 format_reward_cutoff: int = 300 ``` --- # PART 9: TESTING — COMPLETE SUITE INCLUDING AUDIT FIX TESTS ## 9.1 Test Execution Order Run levels in order.
