Residual TD3+BC boundary study: evaluation data, code, and pre-registration archive

Evaluation data and pre-registration archive for a pre-specified boundary study ofbase-anchored residual reinforcement learning (Res-TD3+BC) for multi-agent navigation.V3 adds the n=15 seed expansion of the Domain C six-arm main matrix (ADDENDUM A1):per-run final-evaluation CSVs for all 90 runs (six arms × 15 seeds) across fivescenario families under dual noise calibers, paired-contrast and calibrationsummaries, the n=5 sensitivity contrast, the machine-transcribed manuscript tablesand figure, and the three pre-registered addenda (A1: seed-count expansion; A2:base-summary parameterization; A3: transcription-precision gate rule).

All files are listed in MANIFEST.sha256 (sha256 first-16). Keywords: residual reinforcementlearning; behavior cloning; TD3; multi-agent navigation; pre-registration; reproducibility.
