TokTier: Exact Stateful Tokenization for Agentic LLM Serving

- What happened
- TokTier is a stateful tokenization service that reuses token boundaries across agent LLM calls, avoiding full re-tokenization of long transcripts with small appends.
- Why it matters
- Matters for engineers building agentic systems where coding agents resubmit long context after each tool result, causing tokenization to consume up to 64% of time to first token.
- Watch out
- System requires per-request stable-boundary checks and falls back to full tokenization on failure; exact correctness verified against reference tokenizers across 17 families.
