compact-char-tracking-o1
IN premise
Budget tracking uses a running `_char_count` integer, making per-line budget checks O(1) instead of O(n).
Summary
Budget tracking is efficient because it maintains a simple running counter rather than recounting characters each time. This means checking whether the budget has been exceeded takes constant time regardless of how large the output has grown, which keeps the system responsive even for very long outputs.
Dependents
These beliefs depend on this one:
- compact-budget-tracking-is-efficient-and-approximate — The compact module tracks token budgets efficiently through an approximate but computationally fast strategy: O(1) per-line budget checks via a running character count, with token estimation based on chars/4 — a lightweight approximation avoiding external tokenizer dependencies while maintaining accuracy sufficient for budget enforcement.
