 * increasing specificity to limit queries.

/**
 * @experimental
 *
 * @description
 *
 * Execute a `getStateByRange` query of `TokenBurnCounter` entries.
 *
 * The start key will be offset by the configured `lookbackTimeOffset`
 * (derived from the `blockTimeout`) environment variable, using an inverted
 * time stamp.
 *
 * New entries are expected to be composed with a simple key
 * generated based on the inversion of the current `ctx.txUnixTime`.
 *
 * The intent is to avoid reading new entries written in the same
 * block, by choosing a start key that begins a range which
 * will not include new writes.
 *
 * @remarks
 *
 * Unlike many other fetch queries, `fetchKnownBurnCount`
 * iterate over entries extended from the `RangedChainObject`.
 * `RangedChainObject` types do not support composite key queries.
 *
 * @param ctx
 * @param token
