Token bucket with bounded overdraft: refill clock advances only on admission · case 01

After a denial the same interval is refilled again at the next request.

ROOT CAUSE

The refill timestamp is updated only for admitted requests.

THE FAILURE

The refill timestamp is updated only for admitted requests.

Unsuccessful approach: Holding the clock while in debt refills the debt interval repeatedly.

Case contract

Input {capacity, rate (tokens per second), max_debt, requests [[t_s, cost]]} with nondecreasing whole seconds. The bucket starts full; refill is min(capacity, tokens + elapsed*rate) and also repays debt. A request is admitted when the balance is positive and the post-charge balance stays >= -max_debt, so one expensive request may overdraw. Denials change nothing. Return [[decision, balance]].

Why this case matters

Cost-weighted APIs (query units, LLM tokens) let an expensive call overdraw the bucket and repay it from future refill; the overdraft rules decide fairness between cheap and expensive callers.

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 6 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

Verification & scope

A deterministic, bounded teaching model with stipulated constants and pre-hashed or explicitly hashed inputs; it is not a production implementation and makes no claim of conformance to any library or paper beyond the stated contract. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.

Observations recorded using Python 3.12.14 at 2026-09-29T14:48:50.250652+00:00.
