Cheap poll: has the spending authority over this Safe changed since you last looked? You pass the fingerprint this route gave you last time; it recomputes the current one and compares. Call it with no fingerprint to get a baseline. The fingerprint covers owners, threshold, guard, moduleGuard, the singleton implementation, and the whole module graph including the owners and threshold of modules that are themselves Safes -- a change one level down flips it, which a flat owner list would miss. It deliberately excludes the nonce, so ordinary transactions do not read as an authority change. Nothing is stored on our side: you hold the baseline, so there is no account and no subscription. No archive reads either, which is why this is cheap; when it reports changed, buy GET /safe-signer-drift for what changed and in which block. A truncated walk returns indeterminate, never unchanged. Required: chain_id and address. Optional: fingerprint.
