Hash Collision Risk Analysis (15,000 Items) using the SHAKE256 Algorithm

The following table illustrates the probability of at least one collision occurring within a dataset of 15,000 unique inputs based on the hexadecimal character length.

Hex Length	Total Combinations	Prob. of Collision	Risk Level	Safety Context
8	$4.29 \times 10^9$	~2.6%	🔴 High	1 in 38 chance; unsafe for production.
10	$1.09 \times 10^{12}$	~0.01%	🟡 Moderate	1 in 10,000 chance; risky for primary keys.
12	$2.81 \times 10^{14}$	~0.00004%	🟢 Low	1 in 2.5 million; very safe for most apps.
14	$7.20 \times 10^{16}$	< 0.0000001%	🔵 Safe	1 in 1 billion; negligible risk.

 * @property {number} [ttlMs] - Time-to-live in milliseconds for cached entries. If not specified, entries may be cached indefinitely.
 * @property {string[]} [cacheMethods] - Array of method names that should have their results cached. If not specified, no methods will be cached by default.
 * @property {string[]} [invalidateOn] - Array of method names that, when called, should invalidate the cache. Useful for clearing cache after data mutations.
