… exception Replace AllPathsMaskedError exception with -1 return value when all paths are masked. When no feasible paths exist, this is a normal simulation condition that contributes to blocking probability metrics, not an exceptional case. Using exceptions for control flow was an anti-pattern. Changes: - Remove AllPathsMaskedError class from base.py - Update all policy implementations (KSP-FF, 1+1, BC, IQL) to return -1 - Simplify action_masking.py fallback logic (no try/except needed) - Update all tests to check for -1 instead of catching exception - Move policy tests from rl/policies/tests/ to tests/rl/policies/ for consistency with other RL test organization 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Added comprehensive survivability-related configuration sections across all config files and templates including: - Offline RL settings for policy configuration - Dataset logging settings for training data collection - Recovery timing parameters for failure simulation - Protection settings for network resilience Updated logging configuration to support dataset logging requirements. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Implemented full integration of DatasetLogger into the simulation engine
to enable offline RL dataset collection during simulations.
Changes:
- Added DatasetLogger initialization in SimulationEngine.__init__ with
proper directory structure (data/training_data/{network}/{date}/{time}/{thread}/)
- Implemented _log_dataset_transition() to capture state-action-reward
transitions after each routing decision
- Ensured logger is properly closed on simulation completion
- Added all survivability configuration sections to schema.py:
* dataset_logging (log_offline_dataset, dataset_output_path, epsilon_mix)
* offline_rl_settings (policy_type, fallback_policy, device)
* recovery_timing (protection_switchover_ms, restoration_latency_ms, etc.)
* protection_settings (protection_mode)
* routing_settings (route_method, k_paths, path_ordering, precompute_paths)
* failure_settings (failure_type, geo settings, timing parameters)
* reporting (export_csv, csv_output_path)
- Updated .gitignore to exclude data/training_data directory
Dataset format:
Each transition includes state (src, dst, bandwidth, k_paths), action
(selected path index), reward (+1.0/-1.0), action_mask (path feasibility),
and metadata (request_id, arrival_time, decision_time_ms).

Changed sim_start format from '%m%d_%H_%M_%S_%f' to '%H_%M_%S_%f' and created separate self.date to avoid date duplication in paths.

Fixed multiple critical bugs in simulation and dataset generation:
1. Erlang loop bug: BatchRunner was ignoring erlang_start/stop/step
parameters and defaulting to erlang=300. Now properly reads config
values and makes erlang_stop inclusive.
2. CLI default override bug: --max_iters had default=3 in CLI parser,
which was overriding config file values. Changed to default=None
to respect config files.
3. Last iteration save: Made explicit check to ensure last iteration
always saves statistics regardless of save_step value.
4. Dataset file naming: Added erlang value to dataset filename
(dataset_erlang_{erlang}.jsonl) so each traffic volume gets its
own file instead of overwriting.
5. Dataset metadata: Added erlang and iteration fields to each
transition in the dataset for better tracking.
Files changed:
- fusion/cli/parameters/traffic.py: Remove default=3 from max_iters
- fusion/sim/batch_runner.py: Fix erlang parameter reading
- fusion/sim/network_simulator.py: Make erlang_stop inclusive
- fusion/core/simulation.py: Fix save logic, dataset naming, metadata
- fusion/reporting/dataset_logger.py: Revert append mode to write mode

…ture Resolve configuration duplication issues by implementing a hybrid system that supports both nested sections and flat backward-compatible access patterns.
