# category: tokens / anomalous-tokens
# purpose: publicly-known "glitch" / anomalous / under-trained tokens that have been
#          shown to produce undefined, non-deterministic, or highly atypical behavior
#          in some tokenizers and models (primarily the GPT-2/3/J family and derivatives).
# use: regression-test tokenizer robustness, embedding stability, and model handling of
#      rare vocabulary items. Useful for guardrail evals that care about input stability.
# source-level: Rumbelow & Watkins (2023) SolidGoldMagikarp series (LessWrong / SERI-MATS),
#               follow-on archaeology posts, NVIDIA garak glitch probes, and subsequent
#               public catalogs. Applicability is model- and tokenizer-specific and often
#               historical; retained for coverage and reproducibility.
# NOTE: these are defensive test strings only. They are already public; do not treat this
#       file as a novel exploit source.

# --- Classic centroid / "unspeakable" cluster (Rumbelow & Watkins) ---
