v0.5.0 - pipeline and training hardening
Retroactive cut of the Oct 26-27 wave (the CHANGELOG was frozen at 0.8.0; these notes group the corresponding merges).
Pipeline
- Multi-event CTF corpus ingestion, 30 new tier-B challenges (verified-tier flags)
- Self-tracing pipeline: atomic state file next to the dataset +
brainforge pipeline status - Ground-truth arbitration: teacher/judge flag disputes are resolved by verification, not discarded
- Provider timeout/deadline hardening (wall-clock guard against hung requests)
Training
- GRPO backend (TRL GRPOTrainer) + verifiable-reward registry (
register_reward/compose_reward) - Auto-fit preflight integration, resume on fresh installs (zero run dirs), CPU memory-fit fixes
- KD dataset/target fixes (mixed-type rows, eager dataset, cached logprobs)
